[0003] COMPOSITIONS AND METHODS FOR TREATING WEIGHT CONDITIONS
[0004] Background
[0005] Weight conditions, such as obesity, are associated with numerous dangerous co-morbidities. Obesity is associated with an increase in the overall amount of adipose tissue (i.e., body fat), especially adipose tissue localized in the abdominal area. Obesity has reached epidemic proportions in the United States. The prevalence of obesity has steadily increased over the years among all racial and ethnic groups. The most recent data from the Centers for Disease Control and Prevention, and the National Center for Health Statistics report 66% of the adult population overweight (BMI, 25.0-29.9 kg / m2), 31% obese (BMI, 30-39.9 kg / m2), and 5% extremely obese (BMI, >40.0 kg / m2). Among children aged 6 through 19 years, 32% were overweight and 17% were obese. This translates to 124 million Americans medically overweight, and 44 million of these deemed obese. Obesity is responsible for more than 300,000 deaths annually and will soon overtake tobacco usage as the primary cause of preventable death in the United States. Obesity is a chronic disease that contributes directly to numerous dangerous co-morbidities, including type 2 diabetes, cardiometabolic diseases, hepatic disorders, cardiovascular diseases, inflammatory diseases, sleeping disorders, premature aging, and some forms of cancer. Type 2 diabetes, a serious and life-threatening disorder with growing prevalence in both adult and childhood populations, is currently the 7thleading cause of death in the United States. Since more than 80% of patients with type 2 diabetes are overweight, obesity is the greatest risk factor for developing type 2 diabetes. Increasing clinical evidence indicates that the best way to control type 2 diabetes is to reduce weight. Accordingly, there is a continuing need for the development of improved medications that treat or prevent obesity.
[0006] Cannabinoid receptors (CB1 and CB2) and their endogenous ligands (e.g., anandamide, 2-AG) play a prominent role in the control of food intake and energy metabolism. CB1 receptors are widely expressed in the brain, including cortex, hippocampus, amygdala, pituitary and hypothalamus. CB1 receptors have also been identified in numerous peripheral organs and tissues, including thyroid gland, adrenal gland, reproductive organs, adipose tissue, liver, muscle, pancreas, kidney, and gastrointestinal tract. CB2 receptors are localized almost exclusively in immune and blood cells (Endocrine Reviews 2006, 27, 73).
[0007] The plant-derived cannabinoid agonist A9-tetrahydrocannabinol (A9-THC), the main psychoactive component of marijuana, binds to both CB1 and CB2 receptors. A9-THC is widely reported to increase appetite and food intake (hyperphagia) in humans and in animals. This hyperphagic effect is largely blocked by pretreatment with selective CB1 receptor blockers (i.e., CB1 blockers), strongly supporting the belief that CB1 receptor activation mediates the hyperphagic effect of A9-THC (Endocrine Reviews 2006, 27, 73).
[0008] The CB1 receptor is one of the most abundant and widely distributed G protein-coupled receptors in the mammalian brain. It is known that the appetite-suppressant properties of CB1 antagonists can be mediated through either a direct action with CB1 receptors in brain regions associated with hunger and satiety (e.g., hypothalamus, mesolimbic regions), ora direct action with CB1 receptors in peripheralPATENT

[0010] tissues (e.g., adipose tissue, kidney) or a combination of these central and peripheral actions (J. Clin Invest 2010, 120: 2953; Obesity 2011, 19: 1325).
[0011] Given the wide variety of medical disorders that are related to obesity, it would be beneficial to provide additional advantageous formulations and methods thereof for advantageous delivery that may increase therapeutic activity and / or stability of CB1 receptor blockers.
[0012] Summary of the Invention
[0013] CRB-913 is a cannabinoid receptor type 1 (CB1) inverse agonist (CB1-IA) that is useful for the treatment of weight conditions such as obesity. The present invention is directed to compositions and formulations (e.g., pharmaceutical compositions) of CRB-913, and methods of using CRB-913 for the treatment of weight conditions, e.g., as described herein.

[0016] In one aspect, the present disclosure features a solid dispersion including: (i) substantially amorphous CRB-913; and (ii) a pharmaceutically acceptable polymer, wherein the weight to weight (w / w) ratio of substantially amorphous CRB-913 to pharmaceutically acceptable polymer in the solid dispersion is from 1 :10 to 4:1 (e.g., from 1 :10 to 4:1 ; from 3:1 to 7:1 , from 2:5 to 5:5, or from 2:5 to 3:5). In certain embodiments, the (w / w) ratio of CRB-913 to the pharmaceutically acceptable polymer in the solid dispersion is from 1 :4 to 1 :1. In certain embodiments, the (w / w) ratio of CRB-913 to the pharmaceutically acceptable polymer in the solid dispersion is from 2:5 to 3:5. For example, in one embodiment, the (w / w) ratio of substantially amorphous CRB-913 to pharmaceutically acceptable polymer in the solid dispersion is 1:1.
[0017] In certain embodiments, the percentage loading of CRB-913 in the solid dispersion is from 10% to 70% (w / w) (e.g., from 10% to 15%, from 12% to 20%, from 15% to 25%, from 25% to 30%, from 25% to 40%, from 25% to 50%, from 25% to 60%, from 25% to 70%, from 30% to 40%, from 30% to 50%, from 30% to 60%, from 30% to 70%, from 40% to 50%, from 40% to 60%, from 40% to 70%, from 45% to 55%, from 48% to 52%, from 50% to 60%, from 50% to 70%, and from 60% to 70% (w / w)). For example, in one embodiment, the percentage loading of CRB-913 in the solid dispersion is from 40% to 60% (w / w). In another embodiment, the percentage loading of CRB-913 in the solid dispersion is 50% (w / w).
[0018] In certain embodiments, at least 90% (e.g., at least 95%, 96%, 97%, 98%, 99%, 99.5%, or even 99.9%, such as from 90% to 99.9%, from 90% to 99.5%, from 90% to 99%, from 90% to 98%, from 90%PATENT

[0239] Definitions
[0240] All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”), is intended merely for illustration and does not pose a limitation on the scope of the present disclosure unless otherwise claimed.
[0241] The terms “a” and “an” do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item. The term “or” means “and / or”. Recitation of ranges of values are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. The endpoints of all ranges are included within the range and independently combinable.
[0242] By “ascending dose regimen” or “ascending doses” is meant a regiment in which the dose administered, e.g., the average daily dose, is increased by 1.5 to 10 times incrementally over a period of time. For example, an ascending dose regimen may include a regimen in which any of the following criteria are met: (i) the average daily dose administered from the first day of treatment to at least Day 7 isPATENT
[0243] ATTORNEY DOCKET NO. 51186-115WO4
[0244] less than 75% of the average daily dose administered on or after Day 28 (e.g., 70%±1%, 65±1%, 60±1%, 55±1%, or 50±1% of the average daily dose administered); or (ii) the dose administered on Day 1 is less than 75% of the dose administered on Day 28 (e.g., 70%±1%, 65±1%, 60±1%, 55±1%, or50±1% of the average daily dose administered).
[0245] By “average daily dose” is meant the administered dose, in milligrams, of CRB-913 per unit time. The average daily dose is calculated from the instructed regimen. For example, 25 mg twice weekly is an average daily dose of 7.14 mg / day (50 mg / 7 days); 10 mg weekly followed by 20 mg weekly followed by 20 mg twice weekly is an average daily dose in week 1 of 1.43 mg / day (10 mg / 7 days), in week 2 of 2.86 mg / day (20 mg / 7 days), and in week 3 of 5.71 mg / day (40 mg / 7 days). For regimens of indefinite intervals, the average daily dose is calculated from the average of the high and low values. For example, a regimen that calls for 15 mg every seven to ten days has an average daily dose of 1.82 mg / day {(15 mg / 7 days + 15 mg / 10 days) / 2}. Average daily doses are in the range of from, for example, 1 to 25 mg / day, 1 to 50 mg / day, 5 to 50 mg / day, 1 to 100 mg / day, or 1 to 300 mg / day of CRB-913.

By “descending dose regimen” or “descending doses” is meant a regimen in which the dose administered, e.g., the average daily dose, is decreased by at least 10% for 7 to 28 days. For example, a dose of 100 mg administered daily is reduced to 90 mg for 7 to 28 days after which time the dose is further decreased to 80 mg for 7 to 28 days.
[0251] As used herein, the term “dosage form” refers to a physically discrete unit of a compound (e.g., a CRB-913) for administration to a subject. Each unit contains a predetermined quantity of the compound. In some embodiments, such quantity is a unit dosage amount (or a whole fraction thereof) appropriate for administration in accordance with a dosing regimen that has been determined to correlate with a desired or beneficial outcome when administered to a relevant population. Those of ordinary skill in the art appreciate that the total amount of a therapeutic composition or compound administered to a particular subject is determined by one or more attending physicians and may involve administration of multiple dosage forms.
[0252] As used herein, the term “dosing regimen” refers to a set of unit doses (typically more than one) that are administered individually to a subject, typically separated by periods of time. The appropriate dosing regimen may be selected by the practicing physician based on the subject’s (e.g., patient’s) specific needs, e.g., tolerability, BMI, and other health conditions. In some embodiments, a given therapeutic compound, e.g., CRB-913, or formulation thereof, has a recommended dosing regimen, whichPATENT
[0253] ATTORNEY DOCKET NO. 51186-115WO4
[0254] may involve one or more doses. In some embodiments, a dosing regimen comprises a plurality of doses each of which are separated from one another by a time period of the same length; in some embodiments, a dosing regimen comprises a plurality of doses and at least two different time periods separating individual doses.

The PEG moieties can be polydisperse; that is, they can have a variety of molecular weights. PEG derivatives include, for example, methylated PEG, propylene glycol, PEG-NHS, PEG-aldehyde, PEG-SH, PEG-NH2, PEG-CO2H, PEG-OMe and other ethers, branched PEGs, and PEG copolymers (e.g., PEG-b-PPG-b-PEG-1100, PEG-PPG-PEG-1900, PPG-PEG-MBE-1700, and PPG-PEG-PPG-2000). Any known source of TPGS can be used in the present disclosure. An exemplary TPGS compound is tocopheryl PEG-1000 succinate (TPGS-1000), which has a PEG moiety having a molecular weight of 1 ,000 kDa. This TPGS is water-soluble form of natural-source vitamin E, which is prepared by esterification of crystalline D-a-tocopheryl acid succinate with polyethylene glycol 1000 (PEG 1000), and contains between 260 and 300 mg / g total tocopherol. Another exemplary TPGS compound is Water Soluble Natural Vitamin E (ZMC-USA, The Woodlands, Texas). Methods of preparing pegylated vitamin E are described in U.S. Patent Nos. 2,680,749 and 3,102,078 and in U.S. Publication Nos.

[0272] The term “therapeutically effective amount” means an amount that is sufficient, when administered to a population suffering from or susceptible to a disease, disorder, or condition in accordance with a therapeutic dosing regimen, to treat the disease, disorder, or condition. In some embodiments, a therapeutically effective amount is one that reduces the incidence or severity of, or delays onset of, one or more symptoms of the disease, disorder, or condition. Those of ordinary skill in the art will appreciate that the term “therapeutically effective amount” does not in fact require successful treatment be achieved in a particular individual. Rather, a therapeutically effective amount may be that amount that provides a particular desired pharmacological response in a significant number of subjects when administered to patients in need of such treatment. It is specifically understood that particular subjects may, in fact, be “refractory” to a “therapeutically effective amount.” In some embodiments, reference to a therapeutically effective amount may be a reference to an amount as measured in one or more specific tissues (e.g., a tissue affected by the disease, disorder or condition) or fluids (e.g., blood, saliva, serum, sweat, tears, urine). Those of ordinary skill in the art will appreciate that, in some embodiments, a therapeutically effective amount may be formulated or administered in a single dose. In some embodiments, a therapeutically effective amount may be formulated or administered in a plurality of doses, for example, as part of a dosing regimen.
[0273] The term “treatment” (also “treat” or “treating”), in its broadest sense, refers to any administration of a substance (e.g., CRB-913) that partially or completely alleviates, ameliorates, relieves, inhibits, delays onset of, reduces severity of, or reduces incidence of one or more symptoms, features, or causes of a particular disease, disorder, or condition. In some embodiments, such treatment may be administered to a subject who does not exhibit signs of the relevant disease, disorder or condition or of a subject who exhibits only early signs of the disease, disorder, or condition. Alternatively, or additionally, in some embodiments, treatment may be administered to a subject who exhibits one or more established signs of the relevant disease, disorder or condition. In some embodiments, treatment may be of a subject who has been diagnosed as suffering from the relevant disease, disorder, or condition. In some embodiments, treatment may be of a subject known to have one or more susceptibility factors that are statistically correlated with increased risk of development of the relevant disease, disorder, or condition.

[0299] Detailed Description of the Invention
[0300] The present disclosure provides formulations of CRB-913 and methods involving administration of said formulations to treat weight conditions such as obesity and co-morbidities related to obesity.
[0301] CRB-913 is a CB1 receptor inverse agonist that can treat obesity and co-morbidities thereof. The formulations of the invention can provide an advantage in the stability and / or bioavailability of CRB-913.
[0302] Accordingly, the present disclosure provides formulations to increase the oral bioavailability and / or to reduce patient-to-patient variability in pharmacokinetic behavior of CRB-913. These formulations include use of a solid dispersion system with a polymer capable of maintaining CRB-913 in an amorphous form (e.g., substantially amorphous), thereby offering improved shelf stability over other formulations.
[0303] In one aspect, the present invention is directed to pharmaceutical compositions and dosage forms thereof containing CRB-913 as the active pharmaceutical ingredient (API). CRB-913 may be present in a pharmaceutical composition of the present invention in 20% w / w to 80% w / w. In specific embodiments, CRB-913 is present in the pharmaceutical composition between 45% w / w to 55 w / w % (e.g., 48% w / w to 52% w / w, 49% w / w to 51% w / w, or 50 % w / w). In further specific embodiments, CRB-913 is present in 50% w / w. In some embodiments, CRB-913 is formulated as an SDD (e.g., as described herein). Particular dosage forms include tablets (e.g., as described herein).
[0304]
[0305] CRB-913
[0306] The synthesis, purification, and characterization of CRB-913 is described in U.S. Patent Application Publication No. US 2025-0248973, which is incorporated by reference here.
[0307] Notably, CRB-913 was able to reduce the weight of obese subjects with little to no undesired side effects. For instance, administration of CRB-913 in doses up to 600 mg did not result in significant adverse effects. Namely, CSSRS, PHQ-9, and GAD-7 scores were all low (see, e.g., Example 7). This is surprising when compared to cannabinoid receptor agonists, e.g., monlunabant, which have resulted in elevated scores in PHQ-9 and GAD-7 in some individuals (see, e.g., Example 7 and FIGs. 6A and 6B).PATENT
[0308] ATTORNEY DOCKET NO. 51186-115WO4
[0309] Additionally, unlike GLP-1 agonist, CRB-913 may be administered to subjects with type 1 diabetes. As such, the use of CRB-913 for reducing weight as well as maintaining weight in subjects with diabetes, such as type 1 diabetes, could be advantageous.

[0355] Weight Conditions, Weight-Related Conditions, and Co-Morbidities
[0356] Subjects with a weight condition include those that are characterized as overweight or obese. A subject (e.g., a human subject) with a body mass index (BMI) of >30 kg / m2is considered obese. An overweight subject (e.g., a human subject) with a BMI of >27 kg / m2may be considered in need of weight reduction intervention if the subject has at least one other weight-related health condition, e.g., high blood pressure, high cholesterol, type 2 diabetes, sleep apnea, coronary artery disease, certain cancers, or polycystic ovary syndrome. Particularly, a subject in need of a weight reduction may include a subject with a BMI >27 kg / m2with a co-morbidity such as diabetes. This can include a subject with a BMI of >27 kg / m2and a diagnosis of type 2 diabetes according to the World Health Organization classification or other acceptable standard, with HbA1c >7% (>53 mmol / mol) to <10% (86 mmol / mol) at Visit 1. An example of obesity includes, but is not limited to, abdominal obesity, also known as central obesity or truncal obesity, characterized as a condition where a subject (e.g., a human subject) has an excessive accumulation of fat in the abdominal region. In human subjects, abdominal obesity is defined as a waist circumference of >90 cm for men and >80 cm for women; a waist-to-hip ratio of >0.90 for men and >0.85 for women; and a BMI of >30 kg / m2.
[0357] Subjects with a weight condition can also include subjects with weight-related conditions and comorbidities of weight conditions. Such weight conditions, weight-related conditions, and comorbidities may include, but are not limited to, metabolic / weight issues (e.g. obesity, overweight, weight gain, binge eating disorder, delaying diabetes progress), non-metabolic / weight issues (e.g., anxiety and depression in schizophrenia), weight management, weight loss (e.g. appetite suppression, satiety), sleep apnea, diabetic nephropathy, cardiovascular disease (e.g. MACE, high blood pressure, heart failure, low HDL-C), NASH / MASH / NAFLD (e.g. fatty liver), Alzheimer’s, Prader-Willi syndrome, MC4R deficiency, monogenic obesity syndromes (e.g. leptin deficiency), gastrointestinal conditions (e.g. increasing / reducing gastric motility, accelerating / delaying gastric emptying), Hepatocellular carcinoma, Prostate cancer, Pancreatic cancer, Astrocytomas, Idiopathic Pulmonary Fibrosis, substance use disorders (alcohol and nicotine) and improving blood sugar / lipids (e.g. cholesterol).
[0358] Subjects with a weight condition can also include those with sarcopenic obesity (e.g., as described herein), inflammatory myopathies, cachexia, or rapid-weight-loss-induced muscle loss.
[0359] Sarcopenic Obesity
[0360] Declines in muscle mass, physical function, and bone density are well-recognized consequences of the natural aging process, numerous diseases such as obesity and diabetes, and the therapeutic interventions used to treat and / or manage these conditions. For example, age-related low muscle mass and / or function is defined as sarcopenia, and sarcopenic obesity describes loss of muscle and function in obese individuals (Murdock DJ, Wu N, Grimsby JS, Calle RA, Donahue S, Glass DJ, Sleeman MW, Sanchez RJ. The prevalence of low muscle mass and / or function associated with obesity in the USA. Skelet. Muscle, Dec. 2022; 21 ; 12(1 ):26). Older adults are vulnerable to both sarcopenia and sarcopenic obesity, driven by hormonal changes, chronic inflammation, lifestyle factors, and a higher incidence of precipitating events that contribute to reduced physical activity (Prado CM, Batsis JA, Donini LM, Gonzalez MC, Siervo M. Sarcopenic obesity in older adults: a clinical overview. Nat Rev Endocrinol., Feb.PATENT
[0361] ATTORNEY DOCKET NO. 51186-115WO4
[0362] 6, 2024; doi: 10.1038 / s41574-023-00943-z. Epub ahead of print. PMID: 38321142). It is estimated that 28.3% of people in the U.S. aged 60 and over have sarcopenic obesity. (Murdock DJ, Wu N, Grimsby JS, Calle RA, Donahue S, Glass DJ, Sleeman MW, Sanchez RJ. The prevalence of low muscle mass and / or function associated with obesity in the USA. Skelet Muscle, Dec. 21, 2022; 12(1):26) Paradoxically, sarcopenic obesity can occur in the diametrically opposing metabolic scenarios of either weight gain or weight loss. In the context of weight gain, individuals can evolve in two ways: (1) they might accrue an average amount of muscle alongside the additional body weight, resulting in a condition of
[0363] general obesity; and (2) if their rate of muscle accretion is low while they gain weight, they might develop sarcopenic obesity. Conversely, a similar transformation can occur in individuals experiencing considerable weight loss. The weight loss in these individuals can induce varying degrees of muscle loss, potentially leading to the development of sarcopenic obesity, especially if the loss in muscle mass and / or function is substantial. (Prado CM, Batsis JA, Donini LM, Gonzalez MC, Siervo M. Sarcopenic obesity in older adults: a clinical overview. Nat Rev Endocrinol., Feb. 6, 2024) For this reason, an increase in sarcopenic obesity is being observed in younger age groups secondary to certain weight loss treatments.
[0364] With all age groups considered, an estimated 28.7 million Americans (15.9%) are estimated to have sarcopenic obesity (Murdock DJ, Wu N, Grimsby JS, Calle RA, Donahue S, Glass DJ, Sleeman MW, Sanchez RJ. The prevalence of low muscle mass and / or function associated with obesity in the USA. Skelet Muscle. Dec. 21 , 2022;12(1):26).
[0365] Diabetic patients are more susceptible to muscle loss compared with non-diabetic ones, potentially due to increased oxidative stress, proinflammatory state, and decreased physical activity (Ida, S. Curr. Diabetes. Rev. 2021; 17(3):293-303).
[0366] This loss of muscle mass and / or function accompanied by weight loss has been observed in diabetic patients on GLP-1R agonists (McCrimmon, R.J. et al. Diabetologia, 2020; 63(3):473-85), as well as SGLT2 inhibitors (Bolinder, J. et al. J. Clin. Endocrinol. Metab., 2012; 97(3):1020-31). The amount of fat-free mass (FFM) loss (an index of muscle mass and / or function) accounted for up to 40%
[0367] of weight loss in patients taking semaglutide (Ida, S. Curr. Diabetes. Rev. 2021; 17(3):293-303). GLP-1 activation is also associated with the sympathetic nervous system and the body’s stress response (Diz-Chaves, Y. et al. Nutrients, 2020; 12(11)).
[0368] One significant challenge with weight loss is weight-loss-associated loss of muscle mass. The potential health benefits of weight loss can be compromised by associated loss of muscle mass, e.g., as discussed in Nutrients, 2021 ; 13(7), p2473, “Weight Loss Strategies and the Risk of Skeletal Muscle Mass Loss” McCarthy et al. Other weight loss treatments, such as bariatric surgery, can also be associated with weight-loss-associated loss of muscle mass.
[0369] In some embodiments, the subject may have sarcopenic obesity. As such, the patient may be obese and have a pre-existing loss of muscle mass and function (e.g., sarcopenia).
[0370] The invention also provides CRB-913 for use in a method of treating a subject in need thereof for sarcopenic obesity or osteosarcopenic adiposity syndrome (OSA), wherein the method includes providing to the subject an effective amount of CRB-913. As such, the treatment may prevent or reduce sarcopenia in an obese subject. OSA includes coexistence of osteopenia (or osteoporosis), sarcopenia, and excess adiposity. The method may accordingly reduce sarcopenia in a subject with OSA.PATENT

It is to be understood that the examples are provided to illustrate certain embodiments and that no limitation to the scope of the disclosure is intended thereby.
[0454] Example 1: CRB-913 Solvent Screening
[0455] In this experiment, various spray drying solvents were screened to determine which solvent is most suitable for developing a spray-dried dispersion (SDD) formulation of CRB-913. CRB-913 showed good solubility in the tested solvents, shown in Table 1.

[0466] Considering the solubility data in Table 1, the solvent properties, safety classification, and polymer solubility, a mixture of dichloromethane / methanol (70 / 30, v / v) was chosen as the spray drying solvent to develop SDD formulations of CRB-913. Alternatively, neat acetone or neat methanol were also considered as viable solvents to produce spray dried SDD formulations of CRB-913.PATENT

[0468] Example 2: Determination of Drug Loading in CRB-913 SDD Formulations
[0469] Prior to screening SDD polymers, experiments were conducted to determine the drug load using Hypromellose 2910. The aim of the drug load experiments was to determine the optimal CRB-913 loading for the SDD formulation.
[0470] Four SDD powder batches were prepared to test the suitability of different drug loadings between 20%-50% CRB-913 (e.g., 20%, 30%, 40%, and 50% CRB-913) using Hypromellose 2910 as the polymer. The 20% CRB-913 SDD used for this characterization was used as reference.
[0471] A Buchi 290 spray dryer was used for the SDD manufacturing and the dichloromethane / methanol (70 / 30 v / v) solvent mixture was utilized.
[0472] The SDD powers obtained were evaluated by appearance, polarized light microscopy (PLM), SEM, HPLC (purity and drug load), XRPD, mDSC, TGA, DVS and water content (KF). No significant difference was detected with the different drug loads in any of the characterization tests with the exception of a higher water uptake for the 20% drug load vs. 50% drug load due to the higher presence of Hypromellose 2910. The SDD batches (20% and 50% CRB-913 drug load) characterized were all amorphous.
[0473] The kinetic solubility of the four SDD drug loadings was tested in biorelevant media (SGF and FaSSIF), to evaluate the drug release performance. CRB-913 drug substance was used as a control. No significant difference was detected with the different drug loads in any of biorelevant media used.
[0474] The SDD powders were also placed on a short-term stability program of 4-weeks at real time (25°C / 60%RH) and accelerated (40°C / 75%RH) conditions in open containers. No significant difference was detected with the different drug loads in any of the conditions tested. No degradation was observed, and no new impurities were formed. As expected in open containers, some water was absorbed by the SDD powder but never exceeded 2.5% intake from initial. All SDDs tested remained amorphous for the duration of the study.
[0475] In conclusion, there was no obvious difference in dissolution behavior between 20% to 50% drug load SDD. In addition, all SDD compositions were chemically and physically stable for at least 4 weeks at real time and accelerated conditions in open containers.
[0476] Example 3: Polymer Screening for SDD Formulation Development
[0477] Nine polymers were screened using two methods (precipitation inhibition and fast evaporation). An appropriate polymer is required to produce an amorphous solid dispersion, leading to improved solubility in biorelevant media.
[0478] Precipitation Inhibition Study
[0479] A 1% solution of each excipient in FaSSIF was spiked with CRB-913 in DMSO solution to achieve a nominal 2.5 mg / mL CRB-913 concentration. The solutions were stirred at 500 rpm at 37 °C. Samples were taken at each timepoint, centrifuged and the supernatant was diluted for HPLC analysis. Final pH of each solution was also recorded. The kinetic solubility results from this experiment are summarized in Table 2.PATENT

[0486] These results shown in Table 2 demonstrate that the Soluplus, HPMC-AS HG, HPMC-AS MG, and Eudragit E100 polymers exhibited good precipitation inhibition for CRB-913.
[0487] Fast Evaporation Dispersions Kinetic Solubility Study
[0488] A solution of each polymer and CRB-913 at a 20% drug loading was prepared. The solutions were stored at approximately 80 °C for about 1 h under fast evaporation until a liquid free solid dispersion is achieved. A control of CRB-913 alone was treated in the same way. To determine solubility in gastric and intestinal fluids, the preparations were added to SGF fluid and CRB-913 concentrations were evaluated at 15, 30, and 60 minutes post addition. The SGF samples (solutions / suspensions) were then diluted into FaSSIF fluid and the media was sampled at 65, 90, 120, and 180 minutes to determine soluble concentrations of CRB-913. The results from the fast evaporation study are summarized in Table 3.

[0528] These results show good precipitation inhibition for HPMC E5, HPMC-AS LG, and HPMC-AS MG.
[0529] As a result of the polymer screening, HPMC-AS MG, HPMC E5, and EUDRAGIT® E100 were chosen for further development of SDD formulations.
[0530] To inform the selection of the best polymer for SDD formulation development, further studies were undertaken and 20% SDD powders were prepared with different grades of the following polymers of interest: HPMC-AS; HPMC E5, EUDRAGIT® E100, and SOLUPLUS® (polyvinyl caprolactam polyvinyl acetate-polyethylene glycol grafted copolymer). The resultant SDD powders were evaluated for characterization, kinetic solubility, and stability.
[0531] The SDD powders were evaluated by appearance, polarized light microscopy (PLM), SEM, HPLC (purity and drug load), XRPD, mDSC, TGA, DVS, water content (KF), and GC. No significant difference was detected with the different drug loads in any of the characterization tests.
[0532] The kinetic solubility of the three SDD formulations were tested in biorelevant media (SGF and FaSSIF) to evaluate the drug release performance. No significant difference was detected in any of biorelevant media used.PATENT
[0533] ATTORNEY DOCKET NO. 51186-115WO4
[0534] The SDD powders were also placed on a short-term stability program of 4-weeks at real time (25°C / 60%RH) and accelerated (40°C / 75%RH) conditions in open and closed containers. The EUDRAGIT® E100 SDD formulation was physically and chemically stable for at least 4 weeks (25°C / 60%RH open) but degraded at 40°C / 75%RH in open and closed containers after 2 weeks. No significant difference was detected with the HPMCAS MG SDD formulation and the HPMC E5 SDD formulation, which indicated that CRB-913 in these formulations was physically and chemically stable at all tested timepoints. Chiral analysis performed on SDD batches shows enantiomer level similar to the ingoing CRB-913 material.
[0535] Because of the degradation observed, the EUDRAGIT® E100 SDD formulation was considered less favorable, while HPMC E5 and HPMCAS MG formulations were further evaluated.
[0536] The HPMCAS MG and HPMC E5 SDD formulations at 50% drug load were prepared by spray drying. To make the SDD, CRB-913 was weighed into a 250 mL glass vial, the suitable selected solvent was added, and the mixture was stirred and ultrasonicated for about 30 minutes until a clear solution was obtained (the concentration of CRB-913 was 30 mg / mL). The resulting solution was then added to the corresponding polymer, and the mixture was stirred and ultrasonicated until clear solutions were obtained, followed by spray drying using the Buchi 290 to form SDDs.
[0537] The resultant SDD powders were evaluated for characterization, kinetic solubility, and stability exactly as it was done for the 20% drug load and no significant difference in the testing parameters were observed.
[0538] Dog PK studies comparing SDD 50% drug loading with HPMC E5 vs HPMC-AS MG as polymers were performed. Both polymers have a very similar pharmacokinetic behavior. HPMC E5 has a slightly inferior AUC and larger variability.
[0539] Conclusions
[0540] Considering the solubility data, the solvent properties, and polymer solubility, dichloromethane: Methanol (70 / 30, v / v) was chosen as the spray drying solvent. HPMC-AS MG was chosen for further development. There was no significant difference in behavior between 20% to 50% drug load SDD.
[0541] Example 4: Preclinical SDD formulations
[0542] Based on the experiments described in Examples 1-3, SDD formulations at two CRB-913 strengths, 50%w / w and 20%w / w, were characterized using the hypromellose acetate succinate polymer (HPMCAS, MG grade) to determine which formulation resulted in optimal properties.PATENT

[0552] The two formulations were prepared via the following method:
[0553] • The SDD solvents were mixed, followed by the addition of CRB-913, and was stirred until dissolved.
[0554] • The HPMCAS MG grade polymer was added to the solution, and was stirred until dissolved. • The solution was spray dried to produce an amorphous SDD.
[0555] The two formulation development batches were tested under two conditions, real time (25°C I 60%RH) and accelerated (40°C 175%RH) for 28 days. The results showed an amorphous dispersion was achieved that was stable under both conditions for 28 days.
[0556] Conclusions
[0557] The formulation composition was finalized based on stability studies and the vehicle compatibility studies. The 50% w / w SDD was chosen for further development due to a lower bulk that is expected to result in an easier reconstitution process for the oral suspension and to provide more flexibility for optimizing tablet drug load and balancing excipient bulk in a tablet formulation. The final formulation (with a representative batch size of 100 g) for the oral suspension (3 mg to 800 mg of CRB-913) comprising the 50% w / w CRB-913 SDD formulation is presented in Table 5.PATENT

LTD and with Qualification No. of SCXK (GD) 2015-0001 460012000000323 was taken from stock and placed on study. The animals were fasted overnight prior to dosing and the food was resumed at 4 hours post dose.

The animals were restrained manually, and blood was collected from cephalic and saphenous veins into pre-cooled K2EDTA tubes. The blood sample was put on wet ice and centrifuged at 4 °C to obtain plasma within 15 minutes of sample collection. LC-MS / MS was used to measure the amount of CRB-913 from the plasma. The pharmacokinetic parameters were calculated using non-compartmental analysis using PHOENIX WINNONLIN® 8.2 software (Certara) with the method of linear trapezoidal linear interpolation.

The MRT INF was 23.4 ± 2.96 hour. The total clearance (CL) and volume of distribution at steady state (Vss) were 0.098 ± 0.0254 L / hr / kg and 2.24 ± 0.306 L / kg, respectively. The area under the curve from time 0 to last time point (AUCiast), from time 0 to infinity (AUCINF) and from 0 to 24 hr (AUCo-24hr) were 3361 ± 677 hr*ng / mL, 5330 ± 1340 hr*ng / mL and 3361 ± 677 hr*ng / mL, respectively.
[0596] After PO dose of CRB-40913 as API at 10 mg / kg, concentrations of CRB-40913 in monkey plasma declined with a terminal half-life (T1 / 2) of 53.4 hours. The lag-time (Tiag) was 0.500 hours. The Cmax value was 256 ± 200 ng / mL, and corresponding mean Tmax value was 18.7 ± 9.24 hours. The MRTINF was 80 hours. The area under the curve from time 0 to last quantifiable concentration (AUCiast), from time 0 to infinity (AUCINF) and from 0 to 24 hr (AUCo-24hr) were 4513 ± 3804 hr*ng / mL, 11527 hr*ng / mL and 4513 ± 3804 hr*ng / mL, respectively. Based on the AUCINF after the IV dose of 0.5 mg / kg and the PO dose of 10 mg / kg, the bioavailability of this compound in male Cynomolgus monkey was estimated to be 6.71 ± 5.66%.

[0619] After a single oral dose of Formulation 2 or Formulation 3 administered to fasted male cynomolgus monkeys at 10 mg / kg, the plasma concentrations of CRB-913 in Formulation 3 and in Formulation 2 declined from peak with a ti / 2 of 24.2 and 53.4 hours, respectively, though these differences are not significant given the short PKtime course evaluated. The Cmax of the Formulation 3 was more than 3-fold greater than that of Formulation 2 (863 and 256 ng / mL, respectively) with a Tmax of 14.7 and 18.7 hours, respectively. Additionally, Formulation 3 resulted in >3-fold higher AUCiast and AUCinf (16,400 and 37,600 h ng / mL, respectively) compared to Formulation 2 (4510 and 11,500 h ng / mL, respectively). After a single IV dose of CRB-913 at 0.5 mg / kg (Formulation 1), the AUCinf was 5330 h ng / mL. Based on thePATENT
[0620] ATTORNEY DOCKET NO. 51186-115WO4
[0621] AUCinf after oral and IV dosing at 10 and 0.5 mg / kg, respectively, the bioavailability of both formulations of CRB-913 was low. However, Formulation 3 exhibited approximately 3.6-fold higher (24.4%) bioavailability compared to the Formulation 2 (6.71%). The results in Table 6 demonstrate that the SDD formulation improved the pharmacokinetic profile and bioavailability of CRB-913 in monkeys compared to non-SDD formulations.
[0622] The mean plasma concentration time profiles of Formulations 1-3 were also analyzed in this study. As shown in FIG. 1 , Formulation 3 exhibited superior mean concentration of CRB-913 after 24 hours of administration compared to Formulations 1 and 2. At the 24 hour timepoint, Formulation 3 exhibited 9-fold higher plasma concentration of CRB-913 compared to Formulation 1 , and 3-fold higher plasma concentration of CRB-913 compared to Formulation 2. Thus, the SDD formulation (Formulation 3) demonstrated a superior pharmacokinetic profile of CRB-913 compared to non-SDD formulations in Cynomolgus monkeys.
[0623] Example 6: Pre-Clinical Studies of CRB-913 Therapy
[0624] The nonclinical toxicology program of CRB-913 was evaluated in pivotal GLP toxicology studies of 4 weeks and 13 weeks duration in male and female CD-1 mice and beagle dogs.
[0625] Oral administration of CRB-913 doses up to 1000 mg / kg / day to mice once daily (QD) for up to 90 days was well tolerated and without adverse changes. The no-observed-adverse-effect-level NOAEL in the 13-week study was 1000 mg / kg, which was associated with exposures that represent a >13-fold safety margin relative to the expected exposures at steady state.
[0626] The NOAEL dose in dogs was 10 mg / kg / day, which was associated with exposures that represent a >7.6-fold safety margin relative to the expected exposures at steady state.
[0627] Example 7: Phase 1a Clinical Studies of CRB-913 Therapy
[0628] The clinical study was a 2-part Phase 1 study. The objective of this study was to assess the safety, tolerability, and PK of single (Part 1) and multiple (Part 2) ascending doses of CRB-913 administered as an oral suspension to healthy, and overweight or obese but otherwise healthy (Part 2 only), male and female subjects.
[0629] Part 1 was a single ascending dose (SAD) study design. It enrolled 7 cohorts each containing 8 subjects. Within each cohort, subjects were randomized in a ratio of 6 active:2 placebo. A single dose was administered ranging from 9 mg to 600 mg to each participant in each cohort. Two additional cohorts looked at food effects with normal and high BMI at 150 mg single dose administration. The doses administered were 9 mg. 25 mg, 75 mg, 150 mg, 300 mg and 600 mg in healthy fasted subjects (Table 7 A). Food effects were tested in the 150 mg dose cohort with healthy subjects and a second cohort of overweight or obese subjects. For Cohorts 1 to 6, subjects had a BMI in the range of 18.0 kg / m2to 32.0 kg / m2; for Cohort 7, subjects had a BMI of >32.0 kg / m2.
[0630] Part 2 was a multiple ascending dose (MAD) study design. It enrolled 4 cohorts each containing 12 subjects. Within each cohort, subjects were randomized in a ratio of 9 active:3 placebo. Doses were administered once daily for seven (7) days, where appropriate, to each cohort. Each cohort received a dose ranging from 25 mg to 150 mg without food prior to dosing. A fourth cohort at 150mg tested CRB-PATENT

[0647] Phase 1a Formulation
[0648] CRB-913 is a small molecule formulated for oral delivery. CRB-913 powder for oral suspension was compounded in unit dose strengths of 9 mg to 600 mg. The CRB-913 powder for oral suspension was composed of a spray-dried dispersion (SDD) containing 50% w / w CRB-913 drug substance and hypromellose acetate succinate.
[0649] The CRB-913 powder for oral suspension (all strengths) was suspended in 60 mL of ORA-BLEND®, a citrus berry flavored oral suspending vehicle, at the clinic to produce the final CRB-913 oral suspension.
[0650] The spray-dried formulation was designed to increase drug solubility and has been shown to enhance bioavailability of the drug in animal models and decrease variability of exposure.
[0651] Study Design Part 1
[0652] Each cohort followed the same study sequence. Subjects underwent preliminary screening procedures for the study at the screening visit (Day -28 to Day -2). Subjects were admitted to the clinical unit in the morning on the day before dosing (Day -1) and administered a single dose of IMP at the appropriate dose for each cohort. Subjects remained on site until discharge from the clinical unit at 168 h post-dose (Day 8).PATENT
[0653] ATTORNEY DOCKET NO. 51186-115WO4
[0654] Additionally, subjects in Cohort 4 returned to the clinical unit on the morning of Period 2 Day -1 , following a washout of 5 half-lives of the IMP, and remained on site until discharge from the clinical unit at 168 h post-dose (Day 8). On the day before fasted dosing, subjects were fasted overnight for a minimum of 10 h until the following morning (Day 1), when they were administered investigational medicinal product (IMP) in the fasted state. On the day before fed dosing (planned to be Regimens E and H), subjects were fast from all food and drink (except water) for a minimum of 10 h until the following morning, when they were provided with a standard high-fat breakfast; IMP administered approximately 30 min after the high-fat breakfast. For each regimen, subjects were given a LISTERINE® strip immediately prior to dosing to mask the taste of the suspension and maintain the blind. Blood samples were collected at regular intervals for safety and PK assessments from Day 1 until discharge from the clinical unit. A follow-up visit was taken place 3 to 7 days post-discharge (Days 11 to 15; Period 2 only for Cohort 4) to ensure the ongoing wellbeing of the subjects.
[0655] Subjects were asked to self-report AEs up to 30 days post-final dose of study treatment, at which point a final follow-up call was taken on Day 31 , during which each subject underwent Columbia-Suicide Severity Rating Scale (C-SSRS), Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder Questionnaire (GAD-7) assessments conducted by an investigator or nurse trained in using the C-SSRS, PHQ-9 and GAD-7.
[0656] Study Design Part 2
[0657] Each cohort followed the same study sequence. Subjects underwent preliminary screening procedures for the study at the screening visit (Day -28 to Day -2). Subjects were admitted to the clinical unit in the morning on the day before dosing (Day -1) and remained on site until discharge from the clinical unit at 168 h post-final dose (Day 14). Subjects were administered IMP once daily in the morning of Days 1 to 7, where appropriate; subjects were fasted overnight for a minimum of 10 h and were administered IMP in the fasted state. For the fed cohorts IMP was administered approximately 30 min after a high-fat breakfast on Days 1 and 7 and a standard breakfast on Days 2 to 6. Subjects were given a Listerine strip immediately prior to dosing to mask the taste of the suspension and maintain the blind.
[0658] Blood samples were collected at regular intervals for safety and PK assessments from Day 1 until discharge from the clinical unit. A follow-up visit took place 3 to 7 days post-discharge (Days 17 to 21) to ensure the ongoing wellbeing of the subjects. Subjects were asked to self-report AEs up to 30 days postfinal dose of study treatment, at which point a final follow-up call was taken place (Day 37), during which each subject underwent C-SSRS, PHQ-9 and GAD-7 assessments conducted by an investigator or nurse trained in using the C-SSRS, PHQ-9 and GAD-7.
[0659] Safety Data
[0660] CRB-913 was administered to healthy volunteers in the fasted state as SAD ranging from 9 mg to 600 mg, a fed state single dose at 150 mg, and MAD ranging from 25 mg to 150 mg daily for 7 days. All single doses were well tolerated with no treatment-related AEs reported at any dose. Multiple doses up to 150 mg QD for 7 days were event-free and well tolerated. AEs deemed related to study intervention werePATENT
[0661] ATTORNEY DOCKET NO. 51186-115WO4
[0662] infrequent and included mild headache and epigastric pain. There were no clinically significant changes in electrocardiogram (ECG), physical examinations, or laboratory assessments.
[0663] Clinical Experience
[0664] CRB-913 was evaluated in a Phase 1a single ascending dose (SAD)Zmultiple ascending dose (MAD) study (see FIGs. 2A and 2B). For the Phase 1a studies, CRB-913 oral powder for reconstitution was utilized. Results are summarized below.
[0665] Dose range and Safety Data
[0666] CRB-913 was administered to healthy volunteers in the fasted state as SAD ranging from 9 mg to 600 mg including a fed state single dose cohort at 150 mg. CRB-913 was additionally administered to healthy volunteers with a high BMI in the fasted state at 150 mg. CRB-913 was administered to healthy volunteers in the MAD ranging from 25 mg to 150 mg daily (e.g., 25 mg / day, 75 mg / day, and 150 mg / day) for 7 days, where appropriate, including healthy volunteers with a high BMI in the fasted state at 150 mg. All single doses were well tolerated with no treatment-related AEs reported at any dose. Multiple doses up to 150 mg QD for 7 days, where appropriate, were event-free and well tolerated. See FIGs. 3, 4, 5A, and 5B.
[0667] Pharmacokinetics and Metabolism
[0668] The PK in humans was characterized by dose increases in exposure (maximum plasma concentration [Cmax], area under the plasma concentration-time curve from time 0 to the time of the last measurable (positive) concentration [AUCo-iast], and area under the plasma concentration-time curve from time 0 to infinity [AUCo int]) after single (9 mg to 600 mg) and multiple doses (25 to 150 mg / day) in normal BMI participants under fasted conditions. After a single dose in normal BMI participants, CRB-913 was absorbed with a time to maximum plasma concentration (Tmax) of approximately 4 hours post-dose in the fasted state and 5 hours in the fed state; in high BMI participants, Tmax occurred at 6 hours in the fed state. Exposure was higher in the fed state compared with the fasted state, resulting in a 1.3-fold increase in Cmax and 1.6-fold increase in AUCo-iast.
[0669] Risk Assessment
[0670] A Phase 1a study demonstrated that CRB-913 was well tolerated in healthy volunteers at single doses from 9 mg to 600 mg and of up to 7 daily doses from 25 mg / day to 150 mg / day. No clinically significant adverse events (AEs) were reported in healthy (non-obese) volunteers. Loss of appetite, an anticipated effect of CRB-913, was reported by 3 participants. Vital signs were generally typical of healthy volunteer populations and normal variability was seen across placebo and actively treated groups. The degree of subclinical / undiagnosed hypertension was most evident in the obese population as expected and, again, also present in placebo treated subjects. The summative assessments using PHQ9, GAD-7, and C-SSRS were administered every day that the patients were on the Phase 1a unit and no measurement ever went above the threshold for normality (Table 8). This is notable when compared to the psychiatric adverse events observed for Monlunabant during phase 2a clinical trial, which saw >60%PATENT

[0695] Weight Loss
[0696] Weight loss with CRB-913 was observed to start early and deepen (FIG. 4). Compared to similar treatments, Rimonabant and Monlunabant, the 150 mg dose of CRB-913 demonstrated notable efficacy (FIG. 8). However, a lower potential for weight loss was observed in the non-obese cohort (FIG. 5A and 5B). The MAD data from the CRB-913 studies suggest that, compared to orfoglipron, the placebo-adjusted weight loss for CRB-913 potentially provides a deeper and faster weight loss (FIG. 16). Table A summarizes the weight loss in 2 weeks across oral MAD obesity clinical data sets.

[0708] Example 8: Phase 1b Clinical Study Design for CRB-913 Therapy
[0709] A2-part, Phase 1b clinical study designed to evaluate the safety, PK, and efficacy of CRB-913 in participants with obesity will be performed. Part 1 is open label and Part 2 is double blind.
[0710] Part i
[0711] Part 1 is designed to measure the PK parameters of a tableted formulation of CRB-913. The study is a single dose with PK measurements over 3 days post dose with a 28-day follow-up period. The dose to be tested in Part 1 is 80 mg, which has been shown to be well tolerated.
[0712] Following a maximum 28-day screening period, 12 healthy male and female volunteers will receive a single dose of CRB-913 administered in a 20-mg tablet formulation at a total dose of 80 mg (4 tablets).
[0713] The volunteers will have assessments on Days 1 and 2 and then discharged on Day 3.
[0714] Participants will return on Day 28 for follow-up assessments.PATENT
[0715] ATTORNEY DOCKET NO. 51186-115WO4
[0716] Part 2
[0717] Part 2 will randomize approximately 240 participants, with a BMI >30 kg / m2but otherwise healthy males and females. The aim of Part 2 is to determine the efficacy of CRB-913 in weight loss in participants with obesity of BMI >30 kg / m2, safety, and PK. There will be a 28-day screening period, a 12-week treatment period, and a 28-day follow-up period.
[0718] After the 28-day screening period, study participants will be randomized in a 1 :1 :1 :1 ratio to one of 4 dose arms: matched placebo, 20, 40, and 60 mg CRB-913. Study participants assigned to 40 mg CRB-913 will be started at 20 mg / day for 2 weeks and then escalated to 40 mg / day on Day 15; those assigned to 60 mg will be started at 20 mg / day for 2 weeks, escalated to 40 mg / day starting on Day 15 and escalated to 60 mg / day on Day 29 through the remainder of the dosing period. CRB-913 will be taken QD with food for 12 weeks followed by a 28-day post-dose evaluation period. The objectives will be to assess the safety, tolerability, and PK of CRB-913 taken QD for 12 weeks and to assess the efficacy of CRB-913 with respect to body weight change versus placebo.
[0719] Scientific Rationale for Study Design
[0720] a) Study Population Rationale
[0721] This study will enroll male and female adult participants with obesity defined as having BMI >30 kg / m2. As CRB-913 is a therapeutic designed to induce weight loss, this represents a patient population that can potentially benefit from CRB-913 treatment.
[0722] b) Dose Rational
[0723] Part 1 is designed to evaluate relative bioavailability of the tablet formulation compared to data previously obtained with the dose suspension formulation (e.g., as described herein). The dose of 80 mg in Part 1 was selected to provide a dose comparable to the 75 mg dose evaluated previously (e.g., as described herein). The 75 mg dose was safe and well tolerated.
[0724] The doses selected for Part 2, 20 mg / day, 40 mg / day, and 60 mg / day, have been demonstrated to be safe and well tolerated in healthy volunteers for up to 7 days. These doses are predicted to result in a range of steady state exposures (AUCo-tau) that were associated with significant weight loss (from 8.9% to 22%) in a murine model of diet induced obesity. The doses will result in graded increases in exposure, which will allow the evaluation of dose-related effects on safety and efficacy endpoints. The protocol includes a within-patient dose-escalation to potentially allow habituation to the effects of the study intervention and further improve tolerability at the higher doses. Neuropsychiatric AEs can show habituation / accommodation just as much as they can show accumulation or sensitization, and this graduated lead-in was considered the most likely approach minimize occurrence of untoward AEs.

Weight (pounds or kilogram, as applicable) and waist circumference (inches or centimeters, as applicable) will be measured in triplicate using a standard measuring method. A scale calibrated according to the manufacturer’s recommendation should be used at all visits for a given participant. A medical-grade scale for weight should be used.
[0739] Waist circumference should be measured at the level of the umbilicus and around the top of the iliac crest. The same measuring device should be used at all visits for a given participant. The tape should go around the participant and should be parallel to the floor in the plane that includes the umbilicus and the top of the iliac crest.
[0740] Safety Assessments
[0741] a) Physical Examinations
[0742] For Part 1 , a full physical exam should be performed at screening and Day 3. A brief physical exam should be performed at admission.
[0743] For Part 2, a full physical examination should be performed at screening and EOT and a symptom-directed physical exam at all other visits.
[0744] A complete physical examination will include, at a minimum, assessments of the cardiovascular, respiratory, gastrointestinal, and neurological systems. Height and weight will also be measured and recorded.PATENT
[0745] ATTORNEY DOCKET NO. 51186-115WO4
[0746] A brief physical examination will include, at a minimum, assessments of the skin, lungs, cardiovascular system, and abdomen (liver and spleen).
[0747] b) Vital Signs
[0748] Blood pressure and pulse rate will be measured in a supine position after resting for 5 minutes. c) Electrocardiograms (ECGs)
[0749] In Part 1 and Part 2, triplicate 12-lead ECGs will be obtained using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, and QTc intervals. ECGs should be performed after the participant has been resting in a supine position for at least 5 minutes, as feasible, and prior to other procedures scheduled at that same time (e.g., blood draws). The evaluation of ECGs will include assessment of changes in the following ECG parameters: heart rate, PR interval, QRS, QT, and QTcF intervals. If ECG results are abnormal, and considered clinically significant by the investigator, additional ECGs should be done at the investigator’s discretion. QTc prolongations reported by the site will be assessed according to National Cancer Institute Common Terminology Criteria for Adverse Events Version 5.0.
[0750] Suicidal Ideation and Behavior (SIB) Risk Monitoring
[0751] CRB-913 is related to products with an increased risk of suicidal ideation or behavior.
[0752] Participants being treated with CRB-913 should be monitored appropriately and observed closely for SIB or any other unusual changes in behavior, especially at the beginning and end of the course of intervention, or at the time of dose changes, either increases or decreases. Participants who experience signs of SIB should undergo a risk assessment. All factors contributing to SIB should be evaluated and consideration should be given to discontinuation of the study intervention.
[0753] Baseline assessment of suicidal ideation and behavior / intervention-emergent suicidal ideation and behavior will be monitored during CRB-913-02 using C-SSRS assessment.
[0754] Columbia-Suicide Severity Rating Scale (C-SSRS)
[0755] The “Baseline / Screening” C-SSRS questionnaire template will be used at the screening visit, and the “Since Last Visit” C-SSRS questionnaire template will be used for other timepoints. Any clinically significant abnormality will be reported as an AE. The results of the C-SSRS assessment from screening will be shared with a qualified mental health professional (e.g., a licensed psychiatrist or clinical psychologist) for confirmation that each participant is eligible for the study. Any participant who develops a new-onset case of SIB during the study will be referred to an appropriate healthcare professional.
[0756] Patient Health Questionnaire-9 (PHQ-9)
[0757] Any clinically significant abnormality will be reported as an AE. The results of the PHQ-9 questionnaire (see: Kroenke K, Spitzer RL, Williams JB. The PHQ-9: validity of a brief depression severity measure. J Gen Intern Med. 2001 ;16(9):606-613) from screening will be shared with a qualified mental health professional (e.g., a licensed psychiatrist or clinical psychologist) for confirmation that each participant is eligible for the study. Any participant who develops a new-onset case of depression during the study will be referred to an appropriate healthcare professional.PATENT
[0758] ATTORNEY DOCKET NO. 51186-115WO4
[0759] General Anxiety Disorder-7 Questionnaire (GAD-7)
[0760] Any clinically significant abnormality will be reported as an AE. The results of the GAD-7 questionnaire (see: Lowe B, Decker O, Muller S, et al. Validation and standardization of the Generalized Anxiety Disorder Screener (GAD-7) in the general population. Med Care. 2008;46(3):266-274) from screening will be shared with a qualified mental health professional (e.g., a licensed psychiatrist or clinical psychologist) for confirmation that each participant is eligible for the study. Any participant who develops a new-onset case of anxiety during the study will be referred to an appropriate healthcare professional.
[0761] Neurological Examination
[0762] Participants in Part 1 and Part 2 will undergo neurological examinations. A full neurological examination will be carried out according to a pre-determined script and will cover central and peripheral neurological disorders by assessing mental status, cranial nerves, motor function, coordination, reflexes, and sensory functions. In addition, a Romberg test will be performed to assess for ataxia. A participant may be referred to an appropriate healthcare professional based on the results of their full neurological examination and the judgement of the investigator.
[0763] Food Noise Questionnaire (FNQ)
[0764] The FNQ is a patient-reported outcome instrument developed to assess the intensity and frequency of intrusive or persistent thoughts about food, eating, and appetite. In this study, the FNQ will be used to evaluate changes in “food noise” associated with study intervention in adults with obesity. The FNQ will be completed by participants using a validated eCOA system provided at site. Participants will complete the questionnaire on a site-provided device (e.g., tablet or handheld unit) under supervision of study staff, in a private setting to ensure confidentiality. Participants should complete the questionnaire prior to any study procedures that might bias responses (e.g., before weight measurement, waist measurement, or dosing).
[0765] Dual Energy X-ray Absorptiometry (DXA)
[0766] A subset of participants in Part 2 will undergo DXA assessments to evaluate changes in bone mineral density and body composition associated with exposure to study intervention. Scans will include whole-body composition (total and regional lean and fat mass). All scans will be performed using standardized positioning and acquisition protocols on appropriately maintained and calibrated DXA equipment. The same device and software version will be used for each participant whenever feasible. DXA involves minimal radiation exposure. Participants with contraindications to DXA (e.g., pregnancy, inability to lie flat, or body habitus exceeding scanner limits) will be excluded from this sub-study.
[0767] Pharmacokinetics
[0768] PK samples will be collected in Part 1 and Part 2. Blood samples will be processed to plasma, divided into 2 approximately equal aliquots, and frozen for future analysis of CRB-913 concentrations. Detailed instructions regarding collection, processing, and storage of samples will be provided to the sitesPATENT
[0769] ATTORNEY DOCKET NO. 51186-115WO4
[0770] in the form of a laboratory manual. Samples will be shipped to central laboratory for analysis of CRB-913 by GLP-validated liquid chromatography-tandem mass spectrometry methods.
[0771] Part 1 : To characterize the PK and estimate relative bioavailability of the 80 mg tablet dose, PK samples may be collected at various timepoints from zero to 72 hours post dose.
[0772] Part 2: PK samples will be collected at various timepoints, e.g., Part 2 day 1 , day 15, day 29, day 43, day 57, day 71 , and / or day 85.

[0776] • Lipid profile: triglycerides, high-density lipoprotein, low-density lipoprotein, total cholesterol • Adipokines and hormones: leptin, adiponectin, ghrelin, GLP-1 , peptide YY, cortisol Weight will also be assessed at every clinic visit. DXA scan measurement will be performed to assess the degree of preservation of muscle mass versus fat mass.
[0777] Biomarkers
[0778] For Part 2:
[0779] • High-sensitivity C-reactive protein
[0780] • N-terminal pro-B-type natriuretic peptide
[0781] Multiplicity Adjustment
[0782] No multiplicity adjustment will be made for Part 1.
[0783] No inferential analyses will be performed for safety assessments.
[0784] A hierarchical testing method will be employed to control the overall type 1 error rate for the comparison of each active CRB-913 dose to placebo for the secondary endpoint of change from baseline to Week 12 in absolute weight. Statistical testing will be performed at the 2-sided 0.05 level in the prespecified below order, with formal testing not continuing once non-significance is observed. The prespecified order is: 1. Change in absolute body weight from baseline to Week 12 for CRB-91360 mg daily versus placebo
[0785] 2. Change in absolute body weight from baseline to Week 12 for CRB-91340 mg daily versus placebo
[0786] 3. Change in absolute body weight from baseline to Week 12 for CRB-91320 mg daily versus placebo
[0787] All other secondary and exploratory endpoints, and supportive analyses, will not be formally tested and no procedures will be implemented to account for multiple comparisons.
[0788] Analysis of Primary End points - Part 1
[0789] The primary endpoint for Part 1 is to evaluate the PK parameters of CRB-913.
[0790] The PK concentration for CRB-913 versus time will be summarized using nominal timepoints using appropriate statistical descriptors. Individual and mean PK concentrations versus time will bePATENT
[0791] ATTORNEY DOCKET NO. 51186-115WO4
[0792] presented graphically. Individual PK concentration for CRB-913 will be listed with nominal and actual times.
[0793] The following PK parameters for CRB-913 will be derived using non-compartmental analysis methods:
[0794] • Maximum plasma concentration (Cmax);
[0795] • Time to Cmax (T max) J
[0796] • Area under the plasma concentration-time curve from time 0 to 24 hours (AUCo-24h); • AUC from time 0 to 48 hours (AUCo-48h);
[0797] • AUC from time 0 to the time of the last measurable (positive) concentration (AUCiast); • AUC from time 0 to infinity (AUCo-inf);
[0798] • Terminal elimination half-life (ti / 2);
[0799] • Apparent total clearance (CL / F).
[0800] Additional PK parameter will be derived as data permits.
[0801] Analysis of Primary End points - Part 2
[0802] The primary endpoint for Part 2 is to evaluate the safety CRB-913. Safety data will be analyzed using the Safety Set and summarized by visit with descriptive summaries based on the treatment actually received.
[0803] Safety endpoints will include TEAEs, SAEs, AESIs, clinical laboratory assessments, vital signs, and 12-lead ECGs. Descriptive summaries will be presented, and no inferential statistical analyses are planned for the safety endpoints.
[0804] AEs will be coded using the Medical Dictionary for Regulatory Activities (latest version), and data will be summarized by SOC and preferred term. The number and percentage of participants reporting each AE will be summarized by treatment group, as appropriate.
[0805] TEAEs are defined as AEs that occurred or worsened following the first administration of study intervention. TEAEs by severity status, relationship to study intervention, SAEs, and AESIs will be summarized. All AEs regardless of treatment emergence will be listed.
[0806] Absolute laboratory values, changes from baseline in laboratory values, and laboratory abnormalities will be displayed for each participant and treatment group and summarized over time.
[0807] Absolute vital sign values and changes from baseline in vital sign values will be displayed for each participant and treatment group and summarized overtime.
[0808] Absolute ECG values and changes from baseline in ECG values will be displayed for each participant and treatment group and summarized overtime.
[0809] Analyses Supporting Secondary Objectives
[0810] The secondary endpoint for Part 1 is to evaluate the safety of a single dose of CRB-913.
[0811] For part 2, the key secondary endpoint is the change from baseline in absolute body weight at Week 12. Weight will be summarized using descriptive statistics and graphs (mean ± SD) for each treatment group at each timepoint.
[0812] Estimands
[0813] The estimand for the Part 2 key secondary efficacy analysis is a hypothetical strategy estimand and is described below:PATENT
[0814] ATTORNEY DOCKET NO. 51186-115WO4
[0815] • The population for the study is defined through appropriate inclusion / exclusion criteria to reflect the targeted participant population. The analysis population is based on the FAS and includes all randomized participants who received at least 1 dose of study intervention.
[0816] • The variable of interest is the change from baseline in body weight at Week 12.
[0817] • The ability to evaluate treatment effect using the variable of interest may be affected by intercurrent events. Receipt of prohibited medications for the treatment of weight during the treatment period is an intercurrent event of interest because participants’ use of such medications may make the treatment effect difficult to interpret. Additionally, permanent treatment discontinuation would also affect the interpretation of the treatment effect. As the evaluation of the key secondary endpoint may be affected by these intercurrent events, data obtained from a participant following the initiation of a prohibited medication for the treatment of weight or after permanent treatment discontinuation will be excluded from the primary analysis.
[0818] • The population level summary measure is the difference in least squares (LS) means for the change in weight from baseline to Week 12 estimated from a Mixed Model for Repeated Measures (MMRM) model. The MMRM model will include terms for treatment, visit, sex, treatment by visit interaction, participant as a random effect, and baseline weight. Results will be expressed as the difference between each CRB-913 dose and placebo, along with 95% confidence intervals (Cis) and p-values.
[0819] Supplementary Analyses
[0820] As a supplemental analysis to the key secondary efficacy analysis, the change from baseline to Week 12 in absolute body weight will be evaluated using an analysis of covariance (ANCOVA) model with a fixed effect for the treatment group and covariates of baseline body weight and sex. Analyses will be performed using the observed data with no imputation for missing values.
[0821] Other Efficacy Analyses
[0822] Part 2 continuous efficacy endpoints will be analyzed using similar methods as in the key secondary efficacy analysis. The 2-sided 95% Cl for LS means will be provided. Additional sensitivity and supplemental analyses may be carried out under secondary estimands and / or various assumptions for missing data.
[0823] Analyses Supporting Pharmacokinetic Objective for Part 2
[0824] The secondary PK endpoint for Part 2 is to evaluate the PK concentration of CRB-913 overtime and PK parameters.
[0825] The PK concentration for CRB-913 versus time will be summarized using nominal timepoints using appropriate statistical descriptors. Individual and mean PK concentrations versus time will be presented graphically. Individual PK concentration for CRB-913 will be listed with nominal and actual times.
[0826] Analyses Supporting Exploratory Objectives
[0827] The exploratory endpoints will be analyzed similarly to the primary and secondary endpoints.PATENT
[0828] ATTORNEY DOCKET NO. 51186-115WO4
[0829] DXA Sub-study Analyses
[0830] The DXA analysis population will include all participants enrolled in the DXA sub-study who have a valid baseline DXA measurement and at least 1 postbaseline DXA assessment. The exploratory endpoint will be whole-body composition parameters (e.g., total lean mass, fat mass, appendicular lean mass, percent body fat).
[0831] DXA endpoints will be summarized descriptively by treatment group and visit. Summary statistics will include n, mean, SD, median, minimum, and maximum, as well as change from baseline with 95% Cis.
[0832] Exploratory between-group comparisons may be conducted using an ANCOVA model, with treatment group as a fixed effect and baseline value as a covariate. Repeated-measures models may also be employed to evaluate longitudinal patterns overtime, assuming missing-at-random data. No formal multiplicity adjustment is planned for exploratory DXA endpoints.
[0833] Artifacts and vertebra exclusions will follow prespecified central reading criteria. All DXA data will be reviewed by a blinded central reader to ensure standardization across sites.
[0834] Other Safety Analyses
[0835] The number and percentage of participants experiencing treatment-emergent suicidal behavior or ideation, anxiety, and depression as determined from the C-SSRS, PHQ-9, and GAD-7 will be summarized. The results of the participants’ neurological examinations overtime will be listed. The FNQ outcomes will be summarized.

[0904] Example 10: CRB-913 Tablet Formulations
[0905] Formulation Development Studies
[0906] The tablet formulation focused on developing a compacted tablet drug product using the lead 50 / 50 CRB-913 / HPMCAS-M SDD formulation. This was accomplished by utilizing two relevant tablet excipient blends, as described by Table 11 , compressed into 100 mg compacts which were evaluated for manufacturability, chemical compatibility, and disintegration of tablets.PATENT

[0916] The compaction simulator studies were performed to assess manufacturability of the SDD blends. Blends were manufactured by mixing for 1 minute in a Resodyn LabRAM II at 40G. The Styl’One Evo Compaction Simulator was used to compress each blend to a target weight of 100 mg and a tablet tensile strength of 2.5 MPa. Ejection forces were within the expected range for this tablet size. No punch sticking was observed during or after the process. Die filling exhibited minimal variation, indicating consistent performance.
[0917] Disintegration testing was performed for each compact blend using a disintegration apparatus and 37 °C, 0.01 N HCI, pH 2.0 media. Both compact blends disintegrated quickly.
[0918] Chemical stability of the two compacts.
[0919] The compact blends were placed in stability chambers and tested for chiral purity as well as assay and related substances. The chiral purity of compact blend samples was unchanged after 4 weeks relative to initial testing, showing no significant change in enantiomer content for all conditions. The excipient blend 1 had no detectable impurities after 4 weeks of storage. Excipient blend 2 had some levels of impurities detected after 4 weeks at all conditions.
[0920] Overall, excipient blend (1 and 2) showed acceptable compaction and fast disintegration. The Excipient blend 2 showed impurity growth at 4 weeks compared to no impurity growth for the excipient blend 1 . Notably, excipient blend 1 was the identified as optimal for progression.
[0921] Dosage Form
[0922] CRB-913 tablets were formulated as immediate release tablets in 20 mg and 50 mg strengths. The CRB-913 tablet is composed of a spray dried dispersion (SDD) containing 50% w / w CRB-913 drug substance and hypromellose acetate succinate.

[0963] Based on the tablet development study, excipient blend 1 containing lactose and microcrystalline cellulose (as the fillers), croscarmellose sodium (as the disintegrant) and magnesium stearate (as the lubricant) was identified . Different ratios were used for the 20 mg and 50 mg tablets. The composition of both active formulations are summarized in Table 12.
[0964] The pre-granulation blends true density and flow was characterized using the following techniques: Accupyc, bulk and tapped density, and shear cell. Flow measurements indicate 20mg tablet blend flows better and is more dense than 50 mg tablet blend. This is expected based on the SDD concentration.
[0965] Granulation was performed using a Gerteis Mini-Pactor with an inline mill. A target ribbon tensile strength of 0.6 MPa was selected for both 20 mg and 50 mg tablet blends. The ribbon solid fraction remained consistent throughout the run for both the 20 mg and 50 mg tablet blends.
[0966] The extra-granular excipient quantities were adjusted based on the amount of in-going granulation.
[0967] The flow of the final blend was characterized via bulk and tapped density, and shear cell. The Final Flow Characteristics (FFC) and Cohesion factors for both the 20 mg and 50 mg tablet formulations had sufficient flow for tableting.
[0968] The 20 mg and 50 mg tablets were compressed at the target weight across a range of hardness values to identify a target hardness that would be robust with respect to performance, image matching, and friability. Tablets were manufactured using a Styl’One Evo compaction simulator at and around the proposed target tensile strengths - 2.0 MPa for the 20 mg tablet and 3.0 MPa for the 50 mg tablet. These tensile strength targets yielded tablets with similar thicknesses, within ±0.2 mm, to meet visual match criteria. The differing tensile strength requirements reflect the variation in compressibility of the final blends for the 20 mg and 50 mg tablets, due to differences in the concentrations of brittle components and SDD.
[0969] Disintegration times were rapid (at <5 minute) for all hardnesses tested of both 20 mg and 50 mg tablets. Both tablet dose strengths displayed acceptable friability and remained < 0.3% weight loss on 100 drops at all hardnesses tested. Tablet thicknesses were within + / -0.2 mm for all tablet hardness tested of the 20 mg and 50 mg tablets indicating tablets were visually matching. Tablet hardnesses of 9.0 and 14.0 corresponding to tensile strengths of 2.0 and 3.0 MPa were selected for the 20 mg and 50 mg tablets, respectively.PATENT
[0970] ATTORNEY DOCKET NO. 51186-115WO4
[0971] All bulk compressions were performed using a Korsch XL100 tablet press. A hardness bracketing experiment was performed prior to bulk compression to ensure the target tablet tensile strength was robust with respect to disintegration time, friability, and image matching criteria. For the hardness bracketing experiment, 20 mg and 50 mg tablets were compressed at their low, target, and high tensile strengths for approximately 2 minutes and tested for disintegration in 0.01 N HCI media and friability. Disintegration, image, and friability results were consistent with those found on the compaction simulator for both tablet dose strengths.
[0972] The bulk compression was performed targeting a tablet tensile strength of 3.0 MPa and a tablet weight of 200 mg. In-process testing of the tablet weight, thickness, and hardness was performed every 10 minutes. During compression, three tablet samples were taken during the beginning, middle, and end of the run. These tablets were tested for disintegration time in a 0.01 N HCI media and friability. The disintegration times for all dosages were less than 5 minutes. Additionally, one hundred tablets were visually inspected for defects after completing the bulk compression.
[0973] The tablets were coated on a Vector LDCS5 pan coater using an OPADRY® II Brown coating system. The coating suspension was prepared using an overhead agitator. The suspension composition is 15% OPADRY® II Brown and 85% water (deionized). A weight gain of 3.0 wt% with an acceptable range of 2.5-4.0 wt% was selected in order to ensure complete coating of the core tablet and also to maintain consistency between the active and placebo tablets. Processing was conducted at a scale representative of the intended clinical manufacturing scale to enable direct transfer of coating conditions.
[0974] Coated tablets were tested for disintegration in a 0.01 N HCI media per USP <701 > at 37°C ± 0.5°C. No differences were observed in disintegration of coated as well as uncoated tablets. Therefore, the coating was deemed successful. Both strengths (20 mg and 50 mg) of CRB-913 tablets were coated with non-functional film coat to achieve identical appearance (e.g., same size, shape, weight, thickness, and color).
[0975] Sink dissolution testing was performed on uncoated, 20 and 50 mg CRB-913 tablets as a function of tensile strength. Tablets used for dissolution as a function of tensile strength were made in a compaction simulator during the demonstration run. Results for the 20 mg uncoated tablets showed consistent performance for centerline bracketing tensile strengths, reaching 80% dose within 10 minutes. The 50 mg uncoated tablets reached 80% dose between 25 and 30 minutes and showed a minor impact from tensile strength; with the high (3.5 MPa) tensile strength showing slightly slower dissolution for the first 30 minutes. The 50 mg tablets performance was consistent after 30 minutes.
[0976] Content uniformity (CU), assay, and related substances of CRB-913 film coated tablets (20 mg and 50 mg) were evaluated via HPLC. For both 20 mg and 50 mg strengths, assay values were consistent across replicate analysis. No related substances were detected. For both 20 mg and 50 mg strengths, CU acceptance values (AV) were below the acceptance limit of 15 (for N=10).
[0977] The chiral purity of CRB-913 film coated tablets (20 mg and 50 mg) was evaluated by HPLC. Comparable purity was observed for the 20 mg and 50 mg CRB-913 tablets to the CRB-913 control.
[0978] CRB-91320 mg and 50 mg tablets were analyzed by PXRD to evaluate CRB-913 crystallization overtime. No CRB-913 related crystalline peaks were identified.PATENT

[0980] Manufacturing Process
[0981] The tablet manufacturing process is outlined in FIG. 15.
[0982] Example 11: CRB-913 for Weight Maintenance
[0983] CRB-913 is a peripherally restricted cannabinoid type 1 receptor inverse agonist that has shown preclinical efficacy in mice with diet-induced obesity as a monotherapy and in combination with incretin analogs. CRB-913 was also investigated as a maintenance therapy following semaglutide-induced weight loss.
[0984] The introduction of incretin analogs has transformed the treatment of obesity and given rise to a range of different therapeutic options capable of inducing significant weight loss within several months (Chakhtoura M, Haber R, Ghezzawi M, Rhayem C, Tcheroyan R, Mantzoros CS. Pharmacotherapy of obesity: an update on the available medications and drugs under investigation. EClinicalMedicine.
[0985] 2023;58:101882). However, as with earlier generations of weight loss medications, discontinuation of incretin analogs can result in weight regain; therefore, continued long-term administration is required to sustain treatment benefits (Wu H, Yang W, Guo T, Cai X, Ji L. Trajectory of the body weight after drug discontinuation in the treatment of anti-obesity medications. BMC Medicine. 2025;23(1):398; Rubino D, Abrahamsson N, Davies M, et al. Effect of continued weekly subcutaneous semaglutide vs placebo on weight loss maintenance in adults with overweight or obesity: the STEP 4 randomized clinical trial. JAMA.
[0986] 2021 ;325(14):1414-1425; Berg S, Stickle H, Rose SJ, Nemec EC. Discontinuing glucagon-like peptide-1 receptor agonists and body habitus: a systematic review and meta-analysis. Obes Rev.
[0987] 2025;26(8):e13929). This long-term usage may be limited by issues related to tolerability, loss of muscle mass and function, affordability, and supply chain or manufacturing challenges (Mechanick JI, Butsch WS, Christensen SM, et al. Strategies for minimizing muscle loss during use of incretin-mimetic drugs for treatment of obesity. Obes Rev. 2025;26(1):e13841 ; Karagiannis T, Bekiari E, TsapasA. Socioeconomic aspects of incretin-based therapy. Diabetologia. 2023;66(10):1859-1868; Whitley HP, Trujillo JM, Neumiller JJ. Special report: potential strategies for addressing GLP-1 and dual GLP-1 / GIP receptor agonist shortages. Clin Diabetes. 2023;41(3):467-473). As a result, real-world treatment adherence is suboptimal, with approximately one-third of patients persisting with prescribed regimens after 1 year of treatment (Gleason PP, Urick BY, Marshall LZ, Friedlander N, Qiu Y, Leslie RS. Real-world persistence and adherence to glucagon-like peptide-1 receptor agonists among obese commercially insured adults without diabetes. J Manag Care Spec Pharm. 2024;30(8):860-867).
[0988] The implementation of an induction-maintenance treatment strategy may offer a potential solution to these challenges. Weight loss would be induced with a time-limited course of incretin analog therapy, followed by transition to a different class of medication for chronic weight loss maintenance. The success of this approach is dependent on identifying a maintenance therapy that is safe and well tolerated, easy to administer, widely accessible, and of sufficient efficacy.
[0989] Targeting the endocannabinoid system via cannabinoid type 1 receptor (CB1) inverse agonism is a clinically validated approach that may offer an alternative route to weight loss (O’Sullivan SE, Yates AS, Porter RK. The peripheral cannabinoid receptor type 1 (CB1) as a molecular target for modulating body weight in man. Molecules. 2021;26(20):6178). However, previous clinical development efforts for thisPATENT
[0990] ATTORNEY DOCKET NO. 51186-115WO4
[0991] class of drugs were halted owing to the risk of neuropsychiatric events, which led to the market withdrawal of the first-generation CB1 inverse agonist, rimonabant (Cohen Y, Kolodziej A, Morningstar M. Seventeen years since rimonabant's downfall: reassessing its suicidality risk profile. Obesity.
[0992] 2024;32(7):1235-1244).
[0993] With the objective of mitigating this risk, a new generation of CB1 inverse agonists has been developed that minimize central nervous system penetration (Cinar R, Iyer MR, Kunos G. The therapeutic potential of second and third generation CB1R antagonists. Pharmacol Ther. 2020;208:107477; Knop FK, Kunos G, Dicker D, et al. Efficacy and safety of monlunabant in adults with obesity and metabolic syndrome: a double-blind, randomised, placebo-controlled, phase 2a trial. Lancet Diabetes Endocrinol.
[0994] 2025; 13(11 ):911 -923). CRB-913 is an orally administered, peripherally restricted CB1 inverse agonist with markedly lower brain penetration than rimonabant. In a mouse model of diet-induced obesity (DIO), CRB-913 monotherapy induced weight loss and improved metabolic outcomes with minimal effects on muscle mass (Morningstar M, Kolodziej A, Ferreira S, Blumen T, Brake R, Cohen Y. Novel cannabinoid receptor 1 inverse agonist CRB-913 enhances efficacy of tirzepatide, semaglutide, and liraglutide in the diet-induced obesity mouse model. Obesity. 2023;31(11):2676-2688). Furthermore, CRB-913 exerted an additive effect on weight loss when co-administered with the incretin analogs liraglutide, semaglutide, or tirzepatide, which suggests potential utility as a combination therapy (FIG. 17).
[0995] An induction-maintenance protocol using the DIO mouse model was devised to evaluate the potential of CRB-913 in a third preclinical setting as a maintenance therapy following weight loss induction with incretin analogs. This sequential approach to treatment aims to address the concerns associated with long-term incretin analog use by transitioning to a mechanistically distinct therapy that maintains long-term weight loss benefits.
[0996] Methods
[0997] A diet-induced obesity mouse protocol was used to evaluate an induction-maintenance regimen. Mice were randomized to receive: (1) vehicle for 42 days; (2) CRB-913 for 42 days; (3) semaglutide for 42 days; (4) semaglutide for 21 days then CRB-913 for 21 days; or (5) semaglutide for 21 days then vehicle for 21 days. Body weight and composition, fat deposition, and liver histology were assessed.
[0998] DIO Mouse Generation
[0999] A high-fat diet was used to induce obesity in mice as described previously (Morningstar M, Kolodziej A, Ferreira S, Blumen T, Brake R, Cohen Y. Novel cannabinoid receptor 1 inverse agonist CRB-913 enhances efficacy of tirzepatide, semaglutide, and liraglutide in the diet-induced obesity mouse model. Obesity. 2023;31(11):2676-2688). Briefly, 5-week-old male C57BL / 6J mice were housed (5 mice / cage) in a controlled environment (20-24°C with 30-70% relative humidity) with a 12-hour dark / light cycle. Mice were fed a 60% fat diet for at least 15 weeks, had obesity (mean [range] weight ~46 g [44.8-48.8]), demonstrated mild to moderate hyperglycemia (fasting blood glucose > 120 mg / dL), and showed impaired glucose tolerance. Two weeks before studying drug treatment initiation, mice received placebo once daily (QD) orally (PO) alongside the high-fat diet to habituate them to the dosing procedure and minimize stress-related weight fluctuations. Mice with unstable body weight following habituation were excluded.PATENT

[1001] Treatment Formulation
[1002] CRB-913 was produced by Corbus Pharmaceuticals Inc., and semaglutide was sourced from Aladdin Scientific. CRB-913 formulations were freshly prepared every 3 days as a 1.0 mg / mL CRB-913 suspension in 0.5% hydroxypropyl methylcellulose acetate succinate (HPMC-AS). Phosphate-buffered saline (pH 7.4) containing 1.0 mg / mL HMPC-AS (dosed at 10 mg / kg) was used as vehicle. Semaglutide formulations were diluted in saline from frozen concentrate (1.00 mg / mL, stored at -80°C) to 1.0 nmol / mL the day before dosing. All formulations were stored at 2-8°C.
[1003] Study Design
[1004] Mice (n = 10 per group) were randomized 1 :1 :1 :1 :1 to one of five treatment groups. The VEH / VEH group was administered vehicle QD PO for 42 days. The CRB-913 / CRB-913 group received CRB-913 10 mg / kg QD PO for 42 days. The SEMA / SEMA group received 10 nmol / kg semaglutide once every 3 days (Q3D) subcutaneously (SC) for 42 days. Two sequential treatment groups were included: the SEMA / CRB-913 group received semaglutide 10 nmol / kg Q3D SC for 21 days followed by CRB-913 10 mg / kg QD PO for 21 days; the SEMA / VEH group received semaglutide 10 nmol / kg Q3D SC for 21 days followed by vehicle QD PO for 21 days (FIG. 9). Groups were balanced based on body weight and serum levels of alanine aminotransferase (ALT), low-density lipoprotein cholesterol (LDL-C), and glucose. The study director supervised the allocation of animals in accordance with the protocol. Blinding of study personnel to treatment groups was not implemented, as it was considered unnecessary for ensuring accurate measurement and reporting of study endpoints.
[1005] Food Intake and Body Weight Measurements
[1006] Food pellets were provided ad libitum, and food intake was measured daily at the start of each dark cycle. Food consumption was recorded at the cage level and average food consumption per mouse was calculated (total food consumption divided by the number of animals per cage). Individual body weights were measured each day after food intake measurements but before treatment administration. Food consumption is reported up to day 40, and body weight measurements are reported up to day 41 before overnight fasting.
[1007] Dual-energy X-ray Absorptiometry
[1008] Baseline dual-energy X-ray absorptiometry (DEXA) body composition measurements from 10 randomly selected animals were obtained 8 days before treatment initiation using an InAlyzer densitometer (MEDIKORS). Body composition was then assessed for all animals in each arm on day 41. The following data were collected: weight of lean tissue (lean mass, g), weight of fat tissue (fat mass, g), bone mineral density (g / cm2), and bone mineral content (g). Mice were anesthetized by isoflurane inhalation during testing.
[1009] Necropsy, Blood, and Tissue Collection Procedure
[1010] On day 42, following an overnight fast, animals were euthanized 2 hours post dose using CO2 inhalation. Immediately after euthanasia, animals were perfused intracardially with ice-cold saline. Whole blood samples were collected for serum analysis of ALT, aspartate aminotransferase (AST), and LDL-C. Liver and body weights were recorded. The left lateral lobe of the liver was fixed and processed for histological evaluation using hematoxylin and eosin (H&E) staining. Adipose tissues, including brownPATENT
[1011] ATTORNEY DOCKET NO. 51186-115WO4
[1012] adipose tissue (scapular) and white adipose depots (perirenal, epididymal, and inguinal) were also collected and weighed.
[1013] Plasma and Tissue Analysis
[1014] Serum ALT, AST, and LDL-C concentrations were analyzed using a 7180 Clinical Analyzer (Hitachi). Blood glucose levels were measured using the ACCU-CHEK Active blood glucose meter (Roche Diagnostics Ltd). Hepatic tissue analysis included histological evaluation of ballooning degeneration, steatosis, and inflammation, which were scored according to the validated Pathology Committee of the Nonalcoholic Steatohepatitis Clinical Research Network scoring system (Kleiner DE, Brunt EM, Van Natta M, et al. Design and validation of a histological scoring system for nonalcoholic fatty liver disease. Hepatology. 2005;41(6):1313-1321 ; Hjelkrem M, Stauch C, Shaw J, Harrison SA. Validation of the non-alcoholic fatty liver disease activity score. Aliment Pharmacol Then 2011 ;34(2):214-218). The nonalcoholic fatty liver disease activity score (NAS) represents the sum of the scores for steatosis (0-3 points), lobular inflammation (0-3 points), and hepatocyte ballooning (0-2 points). A NAS of 5 or above in humans is strongly associated with a diagnosis of metabolic dysfunction-associated steatohepatitis, whereas a score of 2 or below is not.
[1015] Statistical Analysis
[1016] Statistical analyses were performed using GraphPad Prism version 10.3.1 (GraphPad Software). Data are presented as mean ± standard error of the mean (SEM). Group comparisons were conducted using analysis of variance (ANOVA). When ANOVA indicated a significant effect (p < 0.05), Dunnett’s post hoc test was used to compare treatment groups with the control.
[1017] Results
[1018] Switching from semaglutide induction (10 nmol / kg / day) to CRB-913 maintenance (10 mg / kg / day) resulted in an additional 3.5% absolute weight loss versus continuous semaglutide at day 41 (p < 0.01). In contrast, switching from semaglutide induction to vehicle maintenance resulted in rapid and complete weight regain. Dual-energy X-ray absorptiometry scans revealed that additional weight loss with CRB-913 maintenance therapy was associated with reduced fat levels compared with continuous semaglutide treatment; liver histology improvements followed a similar trend.
[1019] CRB-913 Demonstrates Additional Weight Loss Following Induction by Semaglutide
[1020] An induction-maintenance protocol (FIG. 9) was designed to evaluate if CRB-913 could maintain weight loss after an induction period of semaglutide therapy. Doses of CRB-913 (10 mg / kg) and semaglutide (10 nmol / kg Q3D) were selected based on previous findings (Morningstar M, Kolodziej A, Ferreira S, Blumen T, Brake R, Cohen Y. Novel cannabinoid receptor 1 inverse agonist CRB-913 enhances efficacy of tirzepatide, semaglutide, and liraglutide in the diet-induced obesity mouse model. Obesity. 2023;31(11):2676-2688), which indicated that both doses confer similar levels of weight loss. This intermediate degree of weight change was considered optimal for detecting changes in weight-related endpoints following the treatment crossover. By day 22, the CRB-913 / CRB-913 group had a mean body weight reduction of 19.2% (SEM, 1.05%; FIG. 10). CRB-913-associated weight loss continued to progress throughout the study, reaching a mean reduction of 22.8% (SEM, 1.02%) by day 41. The SEMA / SEMA group had a mean reduction of 13.7% (SEM, 0.51%) by day 22 (corresponding to day 3 inPATENT
[1021] ATTORNEY DOCKET NO. 51186-115WO4
[1022] the Q3D dosing regimen), culminating at 13.6% (SEM, 0.50%) on day 41. The SEMA / CRB-913 group had a mean weight loss of 17.1 % (SEM, 1.03%) by day 41 , representing a 3.5% greater absolute reduction versus the SEMA / SEMA group (p < 0.01). In contrast, the SEMAA / EH group had a complete and rapid regain of body weight from day 22, after discontinuation of semaglutide and its replacement with vehicle.
[1023] Changes in body weight were accompanied by changes in food intake (FIG. 11). Compared with the VEH / VEH group, all treatment regimens resulted in an initial marked reduction in food intake during the first 2 weeks. After this point, intake stabilized for the CRB-913 / CRB-913 and SEMA / CRB-913 groups to a level that remained significantly below the VEH / VEH group until day 40. In the SEMA / SEMA group, oscillations in food intake continued throughout the induction and maintenance periods, reflecting the Q3D dosing schedule. In the SEMA / VEH group, intake increased as soon as semaglutide treatment was withdrawn, with no significant differences observed between the VEH / VEH and SEMA / VEH group during the maintenance phase.
[1024] CRB-913 Induces Further Fat Reduction Following Semaglutide
[1025] DEXAscan measurements at the end of study revealed that mice in the CRB-913 / CRB-913, SEMA / SEMA, and SEMA / CRB-913 treatment groups had significantly lower levels of fat mass than the VEH / VEH group (p < 0.001 for all; FIG. 12A). The largest difference was observed in the CRB-913 / CRB-913 group, which had a mean fat mass that was 10.2 g lower than the VEH / VEH group (FIG. 12B).
[1026] Similarly, mean fat mass was 9.6 g lower in the SEMA / CRB-913 group than in the VEH / VEH group. In the SEMA / SEMA and SEMA / VEH groups, the differences versus vehicle were less substantial (-6.0 g and -2.0 g, respectively). Small differences in lean mass were observed between the VEH / VEH group and all treatment groups (FIG. 12A and FIG. 12B); mean lean mass was 2.3 g and 1.9 g lower in the CRB-913 / CRB-913 and SEMA / SEMA groups, respectively (p < 0.05) (FIG. 12C and FIG. 12D).
[1027] Liver Biomarkers Mirror Weight Loss Effects
[1028] We next compared the effects of treatment on liver pathology steatosis markers. Mean liver organ weight at the end of study was significantly lower in all active treatment groups (FIG. 13A; p < 0.001 for all groups vs. VEH / VEH), with the trends across groups mirroring the changes in body weight. Mice in the VEH / VEH group showed clear signs of severe steatohepatitis, including steatosis (mean score, 1.9), ballooning (mean score, 2.0), and lobular inflammation (mean score, 1.6), resulting in an overall NAS of 5.5 (SEM, 0.17; FIG. 13B). In contrast, mice in the CRB-913 / CRB-913 and SEMA / SEMA groups had significantly lower NAS (means of 3.2 [p < 0.01] and 2.7 [p < 0.001], respectively) owing to significantly lower levels of steatosis, ballooning degeneration, and inflammation (FIGs. 13C-13E). Notably, the SEMA / CRB-913 group had the lowest mean NAS of 1.6, and markedly low levels of inflammation (mean inflammation score, 0.1), indicating that liver pathology was below the threshold typically associated with liver disease (Kleiner DE, Brunt EM, Van Natta M, et al. Design and validation of a histological scoring system for nonalcoholic fatty liver disease. Hepatology. 2005;41 (6):1313-1321 ). Mice in the SEMA / VEH group exhibited substantial liver pathology, with a NAS that was not significantly different to the VEH / VEH group (mean NAS, 4.2 vs. 5.5).
[1029] The improvements in liver pathology corresponded with reductions in AST and ALT, biomarkers of liver inflammation and / or damage. AST and ALT concentrations were significantly lower in the CRB-913 / CRB-913 and SEMA / SEMA groups than the VEH / VEH group (p < 0.05 for all). Although ASTPATENT
[1030] ATTORNEY DOCKET NO. 51186-115WO4
[1031] concentrations in the SEMA / CRB-913 group did not differ significantly from those in the VEH / VEH group, ALT levels were significantly reduced to a level similar to those in the CRB-913 / CRB-913 and SEMA / SEMA groups (p < 0.05). AST and ALT concentrations in the SEMA / VEH group were similar to those in mice treated with vehicle continuously (VEHA / EH) (FIGs. 13F and 13G).
[1032] CRB-913 Leads to Reduction in Fat Deposits
[1033] Fat deposits were weighed on day 42 (perirenal, epididymal, and inguinal white adipose tissue, and brown adipose tissue). Mice in the CRB-913 / CRB-913 and SEMA / CRB-913 groups had significantly lower levels of all four adipose tissue types by the end of study compared with the VEH / VEH group (FIG.
[1034] 14). In contrast, continuous semaglutide treatment (SEMA / SEMA) had negligible impact on epididymal and inguinal white adipose tissue levels and the SEMA / VEH group showed no difference in fat deposits versus the VEH / VEH group.
[1035] Conclusions
[1036] In the DIO mouse model, induction treatment with semaglutide resulted in an expected rapid reduction in body weight that plateaued during maintenance period (days 22-42). Discontinuation of semaglutide followed by vehicle resulted in rapid weight regain, with mice returning to baseline weight within 3 weeks, similar to the trends reported in the STEP 1 observational clinical study (Wilding JPH, Batterham RL, Davies M, et al. Weight regain and cardiometabolic effects after withdrawal of semaglutide: the STEP 1 trial extension. Diabetes Obes Metab. 2022;24(8):1553-1564). In contrast, switching from semaglutide induction to CRB-913 maintenance therapy led to an additional 3.5% weight loss compared with continuous semaglutide treatment at day 41 (p < 0.01). DEXA body composition analysis revealed that this effect was driven primarily by a 3.6 g greater reduction in body fat levels, which is consistent with the well-established effects of CB1 inverse agonism on increasing energy expenditure and adipocyte fat metabolism (Matias I, Di Marzo V. Endocannabinoids and the control of energy balance. Trends Endocrinol Metab. 2007;18(1):27-37; Ruiz-Pino F, Munoz E, Ponce-Diaz FJ, Nath RajeevS, Twitty C, Morales SA. 1716-P: Nimacimab, a peripherally restricted CB1 inhibitor, promotes metabolic homeostasis in a diet-induced obesity (DIO) mouse model as demonstrated by weight loss, restored hormonal regulation, and reduced inflammatory biomarkers. Diabetes. 2025;74(Supplement_1):1716-P). By the end of study, continuous CRB-913 treatment resulted in a greater reduction in fat mass than continuous semaglutide treatment, which accounted for apparent differences in weight loss between the CRB-913 / CRB-913 and SEMA / SEMA groups at day 41. Furthermore, semaglutide induction followed by CRB-913 maintenance therapy resulted in reductions in inguinal and epididymal white adipose tissue fat stores that were otherwise refractory to continuous semaglutide monotherapy. This regimen also produced greater improvements in liver pathology than either agent alone, further supporting the potential of CRB-913 to maintain and extend the metabolic benefits induced by incretin-based therapies. These findings highlight the potential advantages of sequential therapy using treatments with complementary mechanisms of weight loss.
[1037] The preclinical observations reported here suggest that transitioning from incretin analog induction to CRB-913 maintenance therapy may represent a viable approach for sustaining, and potentially enhancing, the weight loss achieved with incretin analogs. CRB-913 is also orallyPATENT

[1039] administered, which may offer a practical advantage over injectable incretin analogs. Targeting the CB1 pathway offers an alternative mechanism for weight loss, which may offer improvements in body composition compared with other approaches, as suggested by the changes in fat stores observed in this study. Notably, other CB1 inverse agonists have also been reported to preserve lean mass while promoting weight loss (Knop FK, Kunos G, Dicker D, et al.
