AI Technical Summary
Current treatments for glioblastoma, such as surgery, radiation, and chemotherapy, are inadequate due to the tumor's localization in the brain, resistance to chemotherapies, limited brain tissue repair capacity, migration of malignant cells, disrupted tumor blood supply, tumor capillary-related edema, intracranial hypertension, and neurotoxicity, necessitating the need for additional therapeutic options that are both efficacious and tolerable by patients.
A co-administered combination of glycolysis inhibitors/modulators, such as dichloroacetate and prenyltransferase inhibitors, like perillyl alcohol, is used to prevent or treat glioblastoma multiforme, demonstrating synergistic effects when administered simultaneously.
The combination of dichloroacetate and perillyl alcohol effectively inhibits glioblastoma progression and ameliorates symptoms, offering improved therapeutic outcomes with reduced adverse events compared to individual treatments.

Abstract
Description
Reference No.: P2408WO Combinations of glycolysis inhibitors / modulators and prenyltransferase inhibitors for treating brain tumors
[0001] This application claims the priority benefits of application US 63 / 687,219 filed on August 26th, 2024. Field of the Invention
[0002] The present disclosure relates to therapeutic combinations of glycolysis inhibitors / modulators and prenyltransferase inhibitors and pharmaceutical compositions comprising them for treating brain tumors. The disclosure also provides methods for treating glioblastoma multiforme and other forms of brain cancer using the combinations and pharmaceutical compositions of the disclosure. Background Art
[0003] Glioblastoma, also known as glioblastoma multiforme (GBM) or grade IV astrocytoma, is a fast-growing and aggressive brain tumor. It invades the brain tissue but does not generally spread to distant organs. GBMs can arise in the brain de novo or evolve from lower- grade astrocytoma. In adults, GBM occurs most often in the cerebral hemispheres, especially in the frontal and temporal lobes of the brain. GBM is a devastating brain cancer that can result in death in six months or less, if untreated; hence, it is imperative to seek immediate neuro- oncological and neurosurgical care, as this can impact overall survival.
[0004] The mainstay of treatment for GBMs is surgery, followed by radiation and chemotherapy. The primary objective of surgery is to remove as much of the tumor as possible without injuring the surrounding normal brain tissue needed for normal neurological function. However, GBMs are surrounded by a zone of migrating, infiltrating tumor cells that invade surrounding tissues, making it impossible to ever remove the tumor entirely. Surgery provides the ability to reduce the amount of solid tumor tissue within the brain, remove those cells in the center of the tumor that may be resistant to radiation and / or chemotherapy and reduce intracranial pressure. Surgery, by providing a debulking of the tumor, carries the ability to prolong the lives of some patients and improve the quality of remaining life.Reference No.: P2408WO
[0005] In most cases, surgeons perform a craniotomy, opening the skull to reach the tumor site. This is done frequently with computer-assisted image-guidance and at times using intra- operative mapping techniques to determine the locations of the motor, sensory, and speech / language cortex. Intraoperative mapping often involves operating on a patient while they are awake and mapping the anatomy of their language function during the operation. The doctor then decides which portions of the tumor are safe to resect.
[0006] After surgery, when the wound is healed, radiation therapy can begin. The goal of radiation therapy is to selectively kill the remaining tumor cells that have infiltrated the surrounding normal brain tissue. In standard external beam radiation therapy, multiple sessions of standard-dose “fractions” of radiation are delivered to the tumor site as well as a margin in order to treat the zone of infiltrating tumor cells. Each treatment induces damage to both healthy and normal tissue.
[0007] By the time the next treatment is given, most of the normal cells have repaired the damage, but the tumor tissue has not. This process is repeated for a total of 10 to 60 treatments, usually given once a day, five days a week depending on the type of tumor. The use of radiation therapy provides most patients with improved outcomes and longer survival rates compared to surgery alone or the best supportive care.
[0008] Radiosurgery is a treatment method that uses specialized radiation delivery systems to focus radiation at the site of the tumor, while minimizing the radiation dose to the surrounding brain. Radiosurgery may be used in select cases for tumor recurrence, often using additional information derived from MRS or PET scans. It is rarely used in the initial treatment of GBM.
[0009] Patients undergoing chemotherapy are administered special drugs designed to kill tumor cells. Chemotherapy with the drug temozolomide is the current standard of treatment for GBM. The drug is generally administered every day during radiation therapy and then for six cycles after radiation during the maintenance phase. Each cycle lasts for 28 days, with temozolomide given the first five days of each cycle, followed by 23 days of rest. Lomustine (chemotherapy) and bevacizumab (targeted therapy) are largely used when the tumor progresses, but exhibit very poor, if any, efficacy.
[0010] Thus, GBMs present unique treatment challenges due to localization of tumors in the brain, resistance to chemotherapies, limited capacity of the brain to repair itself, migration of malignant cells to adjacent brain tissue, disrupted tumor blood supply, tumor capillary-relatedReference No.: P2408WO edema and intracranial hypertension, tumor-induced seizures, and neurotoxicity of current therapies. As such, there is a need in the art for additional therapeutic options to treat patients with glioblastoma, which are both efficacious as well as tolerated by patients. Summary of the Invention

[0041] The following detailed description is provided to assist a person having ordinary skill in the art in practicing the present invention. The skilled person could make modifications and variations to the embodiments described herein without departing from the scope of the presentReference No.: P2408WO disclosure. All publications, patent applications, patents, figures, and other references mentioned herein are expressly incorporated herein in their entirety by reference.
[0042] Presently described are compositions and methods useful in the treatment of several types of brain tumors. In particular, co-administered combinations and pharmaceutical compositions comprising a therapeutically effective amount of (a) at least one glycolysis inhibitor / modulator and (b) at least one prenyltransferase inhibitor, as described herein, are useful for (i) preventing, inhibiting the progression of or treating brain tumors or (ii) ameliorating the symptoms associated with brain tumors. More particularly, dichloroacetate and perillyl alcohol are employed as active agents of the co-administered combinations and pharmaceutical compositions of the invention. The combinations, compositions, and methods of the invention are surprisingly and unexpectedly useful for treating glioblastoma multiforme.
[0043] As described below, and as used herein, unless the context indicates otherwise, “co- administration” indicates that the two or more agents, as described herein, are present (e.g., present and / or maintained at therapeutically effective amounts) in the system of the subject at the same time. A person skilled in the art would appreciate that two or more active agents can be administered at substantially the same time or at disparate times, and that the timing of the additional administrations of each of the co-administered active agents will depend upon the particular agents employed and their dosages. For instance, as shown in the Examples below, the co-administered combinations were administered at separate times and different amounts. This is merely an exemplary administration schedule, which would be modified based on the subject, dosages, and the exact agents administered. Thus, co-administration as used herein, and discussed in greater detail below, is merely intended to mean that the co-administered agents are present in the system of the subject simultaneously, e.g., administered to maintain each of the co- administered agents at therapeutically effective amounts in the system of the subject.
[0044] The co-administered combinations and pharmaceutical compositions formulations described herein demonstrate a synergistic effect in that the said combinations and compositions achieve at least one of (a) a greater therapeutic effect (i.e., more efficacious) than the additive therapeutic effect obtained by administration of the constituent ingredients alone, (b) a greater therapeutic effect than achieved by administration of a higher dose of the constituent ingredients alone, (c) a similar or greater therapeutic effect but with a decrease in adverse events or side effects relative to that observed by administration of the constituent ingredients alone (i.e., improvedReference No.: P2408WO therapeutic window) or (d) a similar or greater therapeutic effect at a smaller dose of one or both of the constituent ingredients or a combination thereof. As such, the described combination therapy can also be referred to as, for example, synergistic combinations, synergistic compositions or combinations having synergistically effective amounts.
[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by a person of ordinary skill in the art to which the present invention belongs. The terminology used in the disclosure is for describing particular embodiments only and is not intended to limit the scope of the invention.
[0046] Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise (e.g., as in the case of a group containing a number of carbon atoms in which case each carbon atom number falling within the range is provided), between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and is also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both limits, ranges excluding both limits are also included within the scope of the invention. 1. Definitions of general terms and expressions
[0047] The following terms are used to describe the present invention. In instances where a term is not specifically defined herein, that term is given the meaning that a person having ordinary skill in the art would understand it to have considering the context to its use in describing the present invention.
[0048] 2-deoxy-D-glucose: As used herein, the terms “2-deoxy-D-glucose” and “2DDG” refer to a synthetic glucose analog that acts as a non-metabolizable inhibitor of glycolysis, the primary energy pathway for many cells (C6H12O5, CAS [154-17-6]).
[0049] 6-gingerol: As used herein, the term “6-gingerol” refers to a beta-hydroxy ketone that is 5-hydroxydecan-3-one substituted by a 4-hydroxy-3-methoxyphenyl moiety at position 1. It is believed to inhibit adipogenesis (C17H26O4, CAS [23513-14-6]).Reference No.: P2408WO
[0050] A: As used herein, the articles “a” and the related article “an” refer to one or to more than one (i.e., to at least one) of the grammatical object of the article unless the context clearly indicates otherwise. By way of example, “an element” means one element or more than one element.
[0051] About: As used herein, the term “about” should be understood to mean reasonably close when referring to a value or composition that may be within an acceptable error range for said particular value or composition as determined by one of ordinary skill in the art, which will depend in part on how the value or composition is measured or determined, i.e., the limitations of the measurement system. For example, “about” can mean within 1 or more than 1 standard deviation per the practice in the art. Alternatively, “about” can mean a range of up to 20%. Furthermore, particularly with respect to biological systems or processes, the terms can mean up to an order of magnitude or up to 5-fold of a value.
[0052] Additional active agent: As used herein, the terms “additional active agent” or “additionally active agent” refer to a compound which is used in combination with the glycolysis inhibitor / modulators and prenyltransferase inhibitors of the disclosure (“primary agents”) to assist the primary agents in effecting their intended preventive, inhibitory or treatment functions. In some embodiments, the additional active agent for use herein includes compounds which have a pharmacological activity similar to the primary agents. In some embodiments, the additional active agent is an anticancer agent (e.g., anti-glioblastoma agent), anti-excitotoxic / calcium modulator, anti-inflammatory / microglial modulator, mitochondrial protectant, neuroprotective / antioxidant agent, neurotrophic / synaptic support agent, palliative agent, other neuroprotective / metabolic modulating medication or a combination thereof.
[0053] And / or: As used herein, the term “and / or” should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and / or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and / or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and / or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in anotherReference No.: P2408WO embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

[0168] Various patients with GBM employed the combinations of invention and the methods for using them. A description of the experiences of these patients with the combinations and methods of the invention follows:
[0169] Patient-1: female, 26 years old, 3.5 cm diameter, diagnosed with occipital tumor GBM grade IV, isocitrate dehydrogenase (IDH) and O6-methylguanine-DNA methyltransferase (MGMT) promoter wild types. Patient-1 was a no-option patient with a forecast of three to twelve months of survival. When GBM appeared, Patient-1 underwent a biopsy surgery, then radiotherapy combined with low dosage temozolomide, then temozolomide high doses, with no clinical, nor MRI positive results. She had tumor growth visible at the end of temozolomide (TMZ) treatment and suffered a second partial resection surgery. Patient-1’s clinical condition was poor, suffering tonic-clonic seizures ranging from one to nearly twenty per day. Some of seizures were very severe and refractory.
[0170] Patient -1 suffered at least five different induced coma periods as the only way to stop some of the seizures. She also had a severe hemiplegia event, as well as Cushing syndrome, due to the high doses of dexamethasone applied to contain the inflammation produced by the tumor. She received up to three different antiepileptic drugs at maximum dosage at the same time, which were changed with her evolution (e.g., levetiracetam, phenytoin, valproic acid, and lacosamide). Seizures were refractory to all the treatments received. She received different sublingual or intra- anal benzodiazepines to control seizures once started, with high success. The use of benzodiazepines concomitant with seizures eliminated the need to induce coma.
[0171] Tramadol, codeine, and many other anti-pain products were used for headaches, and extreme bone pain caused by bone infarcts secondary to the excessive use of dexamethasone. Ondansetron and other antiemetics were necessary in some periods, as well as vitamin D and levothyroxine, the former because thyroid was severely affected by the radiotherapy applied.
[0172] Patient-1 initiated POH treatment after the second surgery, from month 13-15 of survival, with no other oncologic treatment, at 55 mg / dose TID (three times per day) via inhalation over a period of about 15 minutes each application.Reference No.: P2408WO
[0173] MRI tracking indicated that the tumor stopped growing at first, for a period of about 6 months, and then slowly and continuously reduced its size. The active regions of the tumor disappeared completely after 4 years of treatment with scars remaining visible by MRI in the brain tissue.
[0174] Clinic manifestations of the tumor gradually tapered off and disappeared. Patient-1 stopped taking most of the medicines mentioned above. She continued with levetiracetam only and taking sublingual lorazepam (Trapax) when seizures appeared. Seizures were the most evident clinical manifestation that stayed for the whole period from the beginning of the disease up to the death of the Patient-1, although their intensity and frequency decreased compared to the first two years. All other symptoms such as vomiting, headache, bone pain, and paralysis disappeared completely or almost completely. The patient complained of a persistent minor difficulty in the precision movements of the fingers. Quality of life (QoL) dramatically improved and maintained for many years, with a Karnofsky index of at least 90%.
[0175] In year 4 of the disease, Patient-1 became pregnant and delivered a healthy boy after a completely normal period of pregnancy.
[0176] Patient-1 developed depression in year 7 of the disease attributed to familial issues. GBM became partially resistant to POH almost simultaneously. Tumor grew very quickly and in 3 months invaded not only the left hemisphere of the brain, but part of the right hemisphere, the corpus callosum and the cerebellum, too.
[0177] Some of the former clinical manifestations returned, plus lack of parallelism in the eyes because of cerebellum invasion, which provoked double vision and equilibrium troubles. Hemiplegia appeared strongly again.
[0178] Patient-1 was declared again as a no-option patient, with a maximum of three months of survival. An additional surgery was performed to remove part of the tumor. Recovery was extremely difficult and painful.
[0179] Patient-1 started taking DCA 333 mg twice daily (BID) in conjunction with POH 55 mg three times daily (TID), by mouth. Patient-1 also used octanoic acid, 200 mg, BID, to avoid neuropathy secondary to the DCA treatment.
[0180] Unexpectedly, Patient-1 showed steady signs of improvement and experienced a dramatic improvement in QoL from year 8 to year 10 of the disease, when the tumor advanced slowly again, and caused difficulties to swallow. She had food and liquid entering in the lungsReference No.: P2408WO because of this, and by the year 10 and 2 months of the disease, contracted pneumonia because of lung aspirations. At this stage, all treatments were stopped due to the deteriorating condition of the patient.
[0181] Patient-1 passed after 10 years, 4 months and 21 days from the initial diagnosis of GBM. Significantly, the typical life span for patients with Patient-1´s genotype is 10.4 months, with a low QoL. Patient-1 survived over 10 years with particularly good QoL, most of the time. During the patient’s final years, the combined use of DCA and POH resulted in the unexpected extension of her expected survival from 3 months to 3 years and 6 months; an almost impossible result, considering the advanced stage and degree of tumor spreading by the time POH and DCA were applied contemporarily.
[0182] Patient-2: male, 60 years old, diagnosed with GBM with wild type IDHs and MGMT. He was treated with resection surgery followed by radiotherapy and chemotherapy with TMZ.
[0183] The tumor progressed by month 10 and a new resection surgery was done on month 11. MRI showed an excellent result, with no active areas of tumor visible in the image (Fig.1A). Fifteen days later the tumor was already present on all the borders of the resection area (i.e., brighter areas around periphery resected area, white arrow; Fig.1B).
[0184] Forty-five days after the surgical intervention, the active tumor had already invaded most of the resection area, with a diameter of 4.8 cm occupied in 30 days (Fig.1C). Patient-2 was given a three-month life expectancy with no viable treatment options.
[0185] Fourteen days after the 4.8 cm diameter image Patient-2 started taking POH, at 55 mg / dose TID via nasally. After several weeks, the dose was increased to 144 mg / dose and the patient started taking also DCA orally BID at 333 mg / dose. Patient-2 also began taking octanoic acid, a neuroprotector, as a palliative strategy to avoid any DCA side effects.
[0186] Sixty days after the 4.8 cm image, and 46 days after starting taking POH / DCA treatment, a new MRI was performed. Unexpectedly, the tumor was only 5.2 cm diameter (i.e., patient started taking POH / DCA 2 weeks after the previous image was taken, thus, the 4 mm increase must be attributed to time when the patient did not take POH / DCA) (Fig.1D).
[0187] Patient-2 maintained a relatively high QoL and no new clinical manifestations appeared up to the end of his life, 5.5 months after starting taking POH / DCA.
[0188] An MRI showed a small progress of the tumor. Patient-2 suffered severe depression and stopped taking any medicine, including dexamethasone, which was critical for avoiding anyReference No.: P2408WO inflammation caused by the pressure exerted by the tumor mass in the brain. He died 3 days later, likely due to high intracranial pressure.
[0189] Patient-2 had a 3-month survival forecast when he started taking POH / DCA. With the use of POH / DCA, patient survival unexpectedly increased to 5.5 months, with no clinical progression, and maintaining a good QoL.
[0190] Patient-3: 70 years old, male, diagnosed with GBM wild type IDH and MGMT, a non- surgical 3 cm diameter tumor with a ki-67 of 55 % (i.e., rapid growth). Patient-3’s tumor was biopsied and then radiotherapy plus. TMZ therapy started at a low dose and increased subsequently to a high dose. POH was given in parallel with TMZ. Sole clinical manifestation was a loss of consciousness for maximum 2 minutes once or twice a day. Had Karnofsky index of almost 100 % during the entire process. Patient-3 had a six-month survival forecast.
[0191] Three months later he started treatment with POH, TID via nasal administration, the dose was increased from 55 mg / dose up to 144 mg / dose in a few weeks. DCA was taken orally at the same time BID at a dose of 333 mg, along with octanoic acid as a neuroprotector. MRI image of the moment the treatment started is seen in Fig.2A.
[0192] Fifty-five days later another MRI was performed (Fig. 2B). The POH / DCA combination showed unexpectedly excellent results, without any progression of the disease, which had been advancing very rapidly before the treatments.
[0193] A new MRI performed three months later showed, even more unexpectedly, no signs of any disease progression. The patient maintained a high QoL during this time but complained about hearing continuous noise. Then, Patient-3 stopped taking POH / DCA and died a few days later, most likely due to brain hemorrhage provoked by the internal pressure caused by the tumor.
[0194] In summary, the co-administration of POH and DCA prolonged both the survival and QoL for the glioblastoma patients, without any relevant adverse effects. Extension of life expectancy was due to prevention of tumor evolution and growth even when the treatment was started at an advanced stage.Reference No.: P2408WO Example 2 In vitro 2-D and 3-D assays with POH-DCA combinations
[0195] Several studies were performed for evaluating the antitumor activity of LMP01, a novel therapeutic candidate combining POH and DCA, in aggressive GBM models, to lay the scientific foundations for its potential clinical translation for GBM management. The experimental objectives involved a series of 2D and 3D in vitro approaches assessing LMP01 direct cytostatic activity on different human GBM cell lines, in comparison to POH and DCA monotherapies, and TMZ as a reference standard-of-care treatment. The following materials were used:
[0196] POH (MW 152.23 g / mol, Sigma Aldrich, USA). Considering the maximum non-toxic dose for cells (1% DMSO), the compound was diluted using dimethyl sulfoxide (DMSO) to reach final working concentrations.
[0197] DCA (MW 150.92 g / mol, Curaltus Ltd, Vilnius, LT). The drug was first solubilized using sterile water to generate concentrated stocks and subsequent dilutions using sterile water were conducted to generate final working concentrations.
[0198] TMZ (MW 194.151 g / mol, Sigma Aldrich, USA). The compound was initially dissolved in DMSO to generate concentrated stocks. Subsequent dilutions using DMSO were conducted to attain final working concentrations, without reaching cytotoxic concentration for cells.
[0199] LN229 (ATCC CRL-2611) is an extremely aggressive human GBM cell model, widely used in biomedical research. It was isolated in 1979 from the right frontal parieto-occipital cortex of a white, 60-year-old, female patient with GBM. It has an epithelial-like morphology and it is tumorigenic in nude mice. It bears a mutation in p53 (TP53) and possible homozygous deletions in the p16 and p14ARF tumor suppressor genes.
[0200] LN18 (ATCC CRL-2610) is a wild-type human brain tumor glioblastoma cell line used in neuroscience research and has an epithelial-like morphology. It was isolated in 1976 from the right temporal lobe of a white, 65-year-old, male patient with glioblastoma.
[0201] T98G (ATCC CRL-1690) is a fibroblast-like cell line that was isolated from the brain of a glioblastoma multiforme white, 61-year-old, male patient. It is commonly used in research to study brain cancer and related molecular mechanisms.Reference No.: P2408WO
[0202] LN229 and LN18 were grown using Dulbecco's modified Eagle's medium (DMEM) culture medium (Gibco, USA) and T98G was grown using DMEM:F12 (1:1) medium (Gibco, USA), in all cases cells were supplied with 10% fetal bovine serum (FBS) (Natocor, Córdoba, AR), 80 μg / mL gentamicin, and 2mM glutamine, in monolayer culture, at 37˚C in a humidified atmosphere of 5% CO2. Cells were harvested using a trypsin / EDTA solution (Thermo Fisher Scientific Inc., USA) diluted in PBS and routinely assessed for mycoplasma. 1. 2D cell model determination of antitumor effect and synergism for POH and DCA
[0203] A high-density log-phase proliferation assay was used to evaluate GBM cellular growth. Briefly, LN229, LN18, and T98G cells were plated in 96 multi-well plate format at a density of 2-3 x 10^3 cells per 100 µL of complete DMEM or DMEM / F12 medium. After 24 h, cells were exposed to POH or DCA (range concentrations of 0.1-2 mM and 5-100 mM, respectively).72 h later exponentially growing cell cultures were fixed for 10 min with methanol and then stained with 0.5% crystal violet solution for another 10 min. Following a washing step, fixed cultures were dried overnight. Quantification for the crystal violet method was performed by absorbance measurement (λ=595 nm) after adding an ethanol / acetic acid 3:1 solution. Values are presented as a percentage of control.6-12 wells per experimental group per independent replicate. The tests were performed by duplicate (independent operators). High resolution photographs were taken from different representative wells from each experimental group.
[0204] To investigate a possible synergistic effect by combining both POH and DCA, different high-density cell proliferation assays were conducted in the exponential phase for 72 h. The potential cooperative effects between drug pairs were evaluated using a combinational matrix design. For this purpose, LN229 cells were seeded at a density of 2 x 10^3 cells per well, allowed to attach overnight, and then treated using optimal (IC50) and suboptimal (IC10 and IC25) concentrations of the drugs.
[0205] Outlier identification, analysis of combination indexes, dose-response curve shifts, isobolograms, dose reduction indexes, and synergy scores, the statistical packages PRISM GraphPad, Compusyn, and SynergyFinder were used for subsequent comparative statistical analysis between experimental groups.Reference No.: P2408WO 2. Tumor cell migration inhibition test
[0206] Transwell® migration assays were conducted to evaluate GBM cell chemotaxis. After overnight starvation (0% FBS), 7.5 x 10^4 LN229 cells were seeded into 8 µm-pore inserts (JetBiofil, Guangzhou, CN) in serum-free DMEM and POH (0.5 mM), DCA (30 mM) or LMP01 (POH 0.5 mM plus DCA 30 mM). Lower chambers were filled with DMEM containing FBS as chemoattractant. 3. Tumor cell migration inhibition test
[0207] After 16 h-incubation with LMP01, cells present in the upper surface of the membranes were removed with cotton swabs and cells that migrated through the insert and attached to its lower surface were fixed, stained, and washed. Migrating cells in 4 randomly selected X200-high power field (HPF) per insert were quantified using the open source QuPath Software v0.3.0, and normalized to control (QuPath, Quantitative Pathology and Bioimage Analysis, University of Edinburgh, GB, qupath.github.io). Performed by independent operators, 12-16 X200-HPF were obtained per experimental group, per independent replicate. 4. 3D cell model antitumor effect
[0208] For spheroid formation, the hanging drop method was used. Briefly, 20 µL of complete medium containing 5000 LN229 cells was seeded on the top cover of a 100mm culture plate and allowed to form a spheroid. After 72 h, the resulting cell structures were transferred to a 96-well plate coated with 50 µL of 1.5% agar to prevent cell adhesion to the plastic. Approximately 7 days after transfer, once the spheroids showed adequate sphericity and a minimum diameter of 200 µm, they were randomly separated into groups and treatment with 0.75-2 mM POH, 15-60 mM DCA or LMP01 (assessing different POH+DCA combos) started. The complete medium, with or without treatment, was renewed twice a week for 10-14 days. Spheroids were photographed twice weekly using a high-resolution optical microscope (Leica Microsystems, Wetzlar, DE) to track each individual spheroid and to calculate its volume throughout the experiment, relative to the initial day of treatment (values at day 0 were taken as 100%). Spheroid diameters were quantifiedReference No.: P2408WO using ImageJ 1.5j8 software (NIH, Maryland, USA, imagej.nih.gov and were subsequently converted to volume using the following formula: 4 / 3*3.14*(diameter / 2)^3.
[0209] Additionally, the impact of the monotherapies and the LMP01 combination therapy was also assessed on 3D LN18 cultures, following the same criteria for spheroid formation and subsequent analysis as explained above with the LN229 model. In contrast to LN229, which forms rapidly growing spheroids, 3D cultures of the human GBM cell line LN18 rapidly decline in size, losing cellular cohesion and integrity. Despite this limitation, the therapeutic impact of LMP01 was evaluated in an ancillary manner on the dynamics of LN183D culture. Combinatorial studies of LMP01 in addition to TMZ.
[0210] Once LMP01 was evaluated in both LN229 and LN18 cellular models, concomitant studies of LMP01 in addition to TMZ were conducted in 3D spheroid and chemotaxis models. For 3D spheroid growth, following the same protocol described above, once the spheroids showed adequate sphericity and diameter, they were randomly separated into groups and treatment with LMP01 (POH 0.75 mM and DCA 15 mM), TMZ 50 µM (Berte N, et al., Oncotarget 2016; 7(41):67235-67250) and its combination, for the LN229 model, and LMP01 (POH 0.5 mM and DCA 30 mM), TMZ 50 µM and its combination, for the LN18 model, was started. The complete medium, with or without treatment, was renewed twice a week for 10-14 days and spheroids were photographed twice weekly. The subsequent analysis was conducted following the same criteria mentioned above. Additionally, Transwell® migration assays were conducted, as previously described.
[0211] After overnight starvation, 7.5 x 10^4 LN229 cells were seeded into 8 µm-pore inserts in serum-free DMEM and LMP01 (POH 0.5 mM and DCA 30mM), TMZ 200 µM and its combination. Lower chambers were filled with DMEM containing FBS as chemoattractant and after 16 h treatment cells were fixed, stained and washed. Migrating cells in 4 randomly selected X200-high power field (HPF) per insert were quantified using the open source QuPath Software v0.3.0 and normalized to control. In vitro assay determinations were conducted from at least 2 or 3 independent experiments, unless stated otherwise, with a variable number of replicates per experiment type ranging from 3-12 per experimental group.
[0212] Statistical analyses were mainly performed using GraphPad Prism 8.0V software, (GraphPad Prism Software, USA). Distribution of data and descriptive statistics were first assessed. Outliers were detected and removed (Prism calculator). For comparisons among 3 orReference No.: P2408WO more experimental groups, ANOVA or its nonparametric equivalent, the Kruskal-Wallis test, were utilized. Subsequently, tests such as Dunnett's test, Tukey's test, comparison of 95% confidence intervals (CI) for the mean (ANOVA) or Dunn's test (Kruskal-Wallis) were employed. For comparisons between 2 groups, either the Student t-test or the Mann-Whitney test were used, depending on the parametric or non-parametric distribution of values, respectively. For the calculation of the half inhibitory concentration (IC50), nonlinear regressions were applied, based on optimal curve-fitting. Differences were considered statistically significant at a level of p<0.05; *p<0.05; **p<0.01; ***p<0.001; ****p<0.0001.
[0213] As a result of this experimental scenario, both POH and DCA displayed a direct and dose-dependent antiproliferative effect on rapidly-growing GBM cell cultures, obtaining IC50values of 1.01 (for LN229 cell line), 0.77 (for LN18 cell line) and 0.76 mM (for T98G cell line) were obtained for POH (Fig. 3), and 33.31 (for LN229 cell line), 32.71 (for LN18 cell line) and 17.96 mM (for T98G cell line) for DCA (Fig. 4). Significant (p<0.05) cytostatic activity was observed from 0.5-0.75 mM for POH, and 12.5-25 mM for DCA concentrations onwards, depending on tumor cell line.
[0214] To confirm synergistic effects of POH and DCA cell proliferation assays on LN229 cultures were conducted using a combinational matrix design. Treatments were conducted using optimal and suboptimal concentrations of each tested compound.
[0215] POH and DCA combination using different concentrations resulted in a marked inhibitory activity on GBM exponential growth, as evidenced in the heat map-based dose-response matrix (Fig. 5). After integrating these results, an average synergy score of 2.88 was obtained using the HSA model (Values >0 represent synergistic interaction between drug pairs) (Fig. 5). Furthermore, synergistic CI values <1 were obtained in 8 out of 9 POH+DCA combinations (Table 1).Reference No.: P2408WO Table 1 Dose POH Dose DCA Effect CI 1.0E-6 1.0E-6 1.0E-6 1.54487 sm
[0216] Representative drug combinations using specific concentrations within high synergistic areas (POH 0.5 mM plus DCA 25 mM, and POH 0.5 mM plus DCA 50 mM) are depicted in Fig. 6. In these combinatorial schemes it is highly evident that dual concomitant exposure of POH in addition to DCA results in a significant anti-GBM activity, improving the therapeutic benefits of either monotherapy alone. In this regard, LMP01 potent combined antiproliferative action may stall the progression of rapidly growing recurrent GBM lesions.
[0217] Continuing with the evaluation of the therapeutic action of LMP01, the impact of this combined therapy on the phenomenon of tumor chemotaxis of GBM cells (Fig.7) was studied. As observed in the control group, vehicle-treated cells exhibited a highly migratory and aggressive phenotype. In this scenario, POH nor DCA as monotherapies were unable to affect GBM migration after short term exposure. On the contrary, LMP01 combination therapy (0.5 mM POH plus 30 mM DCA) displayed a significant inhibitory activity on tumor cell motility of LN229 cells, down modulating chemotactic capacity by 32% in treated cells, outperforming each monotherapy. A non-significant 6% reduction in GBM chemotaxis was observed after DCA treatment at 30 mM.
[0218] The effect of LMP01 on 3D tumor spheroid growth was also evaluated using a model that mimics more closely the in vivo tumor microenvironment compared to traditional two- dimensional cultures (Manduca N, et al., Front Immunol.2023; 14:1175503). First, the effect of POH as monotherapy on LN2293D cell growth was evaluated (Fig. 8). Concentrations of 0.5, 0.75, and 1 mM POH were evaluated, revealing growth inhibition starting at 0.75 mM. The inhibitory effect reached saturation, with no enhancement upon increasing the concentration to 1Reference No.: P2408WO mM. In contrast, 0.5 mM POH showed no effect on 3D cell proliferation. This trend was confirmed by analyzing tumor volume at the end of the experiment (day 14), where both 0.75 mM and 1 mM POH induced a significant reduction in tumor volume compared to the control. Next, the efficacy of DCA as a monotherapy was assessed in the LN229 3D model (Fig. 9). Tested concentrations (15, 30, and 60 mM) demonstrated that growth inhibition was reached starting at 30 mM. This observation aligned with tumor volume measurements at the endpoint (day 14), where both 30 and 60 mM DCA induced a significant reduction compared to control. Both compounds significantly impacted on 3D tumor growth, but with distinct effects: POH induced proliferative arrest (no volume increase compared to day 0), whereas DCA produced a significant volume reduction (40-45% decrease at concentrations = or > than 30 mM). These differences reflect different mechanisms of action for both drugs evaluated.
[0219] Based on the effective concentrations identified in monotherapy assays, various drug combinations were evaluated.
[0220] The 0.5 mM POH plus 30 mM DCA combination revealed that DCA’s inhibitory effect reached saturation, significantly reducing 3D proliferation in both spheroid growth kinetics and endpoint analysis (day 14) (Fig.10). Under these conditions, POH did not exhibit any capacity to enhance DCA’s antiproliferative effect. Independent validation using 0.5 mM POH plus 30 mM DCA in LN183D spheroids showed comparable results at endpoint (day 10). The combination treatment resulted in the greatest significant inhibitory effect on 3D growth compared to the control (84% growth reduction). LMP01 demonstrated superior anti-GBM activity compared with POH at the suboptimal concentration of 0.5 mM concentration (Fig.11).
[0221] Based on these findings, a second drug combination was evaluated in the main experimental model LN229: 0.75 mM POH plus 15 mM DCA. Growth curve analysis revealed that this combination outperformed both monotherapies starting on day 7, achieving a 75% proliferation inhibition by the endpoint (day 14) compared to the control group. Under these experimental conditions, LMP01 combining 0.75 mM POH plus 15 mM DCA, was the treatment capable of significantly impairing 3D growth on day 14 in comparison to vehicle-treated spheroids (Fig.12).
[0222] Strikingly, by endpoint at day 14, LMP01 (0.75 mM POH + 15 mM DCA) therapeutic activity was comparable to that of the standard-of-care chemotherapeutic agent TMZ used at high cytotoxic concentrations (150 μM). Notably, the LMP01 combination significantly performedReference No.: P2408WO TMZ during the early phase of spheroid outgrowth (day 4) (Fig. 13). Collectively, 2D and 3D findings demonstrate that the LMP01-based therapy exhibits superior antitumor efficacy in GBM models compared to either agent alone or standard TMZ treatment at high concentrations.
[0223] To assess potential therapeutic benefits after adding LMP01 to TMZ the combinatorial impact on GBM cell migratory capacity was first evaluated. As shown in Fig.14., the concomitant treatment using LMP01 in addition to high TMZ concentrations resulted in a cooperative inhibitory effect on GBM chemotaxis (41% inhibition), significantly enhancing therapeutic benefits of reference chemotherapy alone (23.8% inhibition).
[0224] In summary, LMP01 has been evaluated in various experimental models of human GBM characterized by high proliferative capacity, invasiveness, and differing MGMT expression status. As previously stated, high proliferation rates in GBM are biologically significant as they correlate directly with tumor aggressiveness, growth dynamics, recurrence, and patient prognosis. Treatment with LMP01 induced a potent cytostatic effect in exponentially growing, extremely aggressive GBM cultures. Using multiple high-density proliferation assays, a 72-hour exposure to LMP01 demonstrated dose-dependent antiproliferative activity when the two rationally selected small molecules were combined at micromolar to low millimolar concentrations.
[0225] The combination therapy outperformed each monotherapy, with synergy confirmed at specific concentration ranges. Moreover, GBM is characterized by its highly infiltrative and migratory phenotype, a major contributor to its lethality and poor prognosis. Notably, LMP01 impaired GBM cell motility, as demonstrated by transwell migration assays. After only 16 hours of treatment, tumor cell chemotaxis was significantly inhibited compared to vehicle controls and individual treatments.
[0226] GBM cells surviving surgical resection and adjuvant therapies can form highly proliferating residual colonies, leading to recurrence and multifocal disease. To address this, LMP01’s effect on 3D GBM growth was assessed using a long-term spheroid progression assay. After two weeks of treatment, LMP01 combination therapy significantly inhibited 3D tumor growth, reducing GBM spheroid volume by up to 75% in comparison to control. This therapeutic activity was comparable to that of the standard-of-care chemotherapeutic agent TMZ used at high cytotoxic concentrations.Reference No.: P2408WO Example 3 In vivo assays with POH-DCA combinations
[0227] In this next example, the therapeutic efficacy of LMP01 was evaluated in an orthotopic glioblastoma model using LN229 cells implantation. For this purpose, LN229 human glioblastoma cells were implanted in the brain of immunocompromised mice (NLAE:NIH (S)-Fox1nu “nude” mice) and then treated with a daily dose of LMP01 using two different administration routes, compared to vehicle-treated control group. The following materials and protocols were used:
[0228] LN229 (ATCC CRL-2611) is an extremely aggressive human GBM cell model, widely used in biomedical research. It was isolated in 1979 from the right frontal parieto-occipital cortex of a white, 60-year-old, female patient with GBM. It has an epithelial-like morphology, and it is tumorigenic in nude mice. It bears a mutation in p53 (TP53) and possible homozygous deletions in the p16 and p14ARF tumor suppressor genes. LN229 cells were grown using Dulbecco's modified Eagle's medium (DMEM) culture medium (Gibco, USA) supplied with 10% fetal bovine serum (FBS) (Natocor, Córdoba, AR), 80 μg / mL gentamicin, and 2mM glutamine, in monolayer culture, at 37˚C in a humidified atmosphere of 5% CO2. Cells were harvested using a trypsin / EDTA solution (Thermo Fisher Scientific Inc., USA) diluted in PBS and routinely evaluated for mycoplasma.
[0229] The LN229 cells where then implanted in the brain of male nude mice, used to perform the in vivo experiment. All animals were 6-8 weeks old and weighed approximately 20 g. All the animals in these studies were produced in the animal facility of the Veterinary Faculty of La Plata University (Buenos Aires, AR). The animals were housed in an animal isolator and animal manipulation was performed in laminar-air-flow units. All animals were given ad libitum access to food and water.
[0230] All animals were anesthetized using i.p administration of ketamine / xylazine (80:20). Sedation was monitored using a gentle toe pinch withdraw reflex. The animal head was positioned and secured in a stereotactic frame (Stoelting, USA). The eyes were moistened with eye drop solution to prevent damage to the animal´s eye. The scalp was disinfected with povidone / iodine and an anterior / posterior incision was made with a sterile scalpel extending from the lambda to just in-between the eyes of the animal. The exposed skull surface was then cleaned using a cotton swab soaked in a 3% hydrogen peroxide solution. A burr hole was made 0.1 mm anterior to bregmaReference No.: P2408WO and 2.3 mm to the right of the midline. A 33G needle (10 µL Hamilton syringe) was inserted to a depth of 3 mm and withdrawn 0.4 mm to a depth of 2.6 mm.2x105human glioblastoma LN229 cells were delivered in 2 µL at a rate of 0.5 µL / min. After injection was completed, the needle was left in the brain for approximately 2 min and then slowly withdrawn over a period of 3-4 min. Then the ear bars were loosened, and the animal was removed from the stereotactic apparatus. To seal the wound, the edges of the incision were re-approximated, cleaned with sterile cotton swabs and veterinarian tissue glue was applied. Finally, the mouse was placed at 37°C until the animal recovered consciousness. Once the mouse was alert and responsive, it was transferred to its original cage.
[0231] Tramadol and ampicillin were administered for the next 5 days after the surgery. POH (MW 152.23 g / mol, Sigma Aldrich, USA) was added to saline and then vigorously vortexed for 5 seconds before every administration. DCA (MW 150.92 g / mol, Curaltus Ltd., Vilnius, LT) was dissolved in saline and diluted in sterile water, which was provided as drinking water ad libitum. The DCA-containing water was replaced three times per week.
[0232] The combination LMP01 i.n. was prepared by adding POH to a DCA solution in saline solution. Prior to each administration, the mixture was vigorously vortexed for 5 seconds.
[0233] All groups received a daily administration (24h±2h) of vehicle or treatment. Control group received intranasal (i.n.) administration of 12.5 µl of saline solution. LMP01 (oral+i.n.) received POH 0.3125 mg / day was administered via i.n. on average, each animal consumed ~1.5 mg / day of DCA through the drinking water. LMP01 (i.n.) received i.n. administration of POH 0.3125 mg / day and DCA 1 mg / day combined. 7 days post-surgery the animals were separated randomly into distinct groups of 4 to 5 mice each.
[0234] The treatment consisted of daily administration of the before-mentioned drugs. All mice were monitored daily, weighed twice a week and consumption of water was registered 3 times / week.
[0235] Animals were euthanized if they met any of the following criteria: weight loss (>20%), physical deterioration, cachexia, abnormal mobility, lethargy, ataxia, and / or a hunched posture. Following this procedure, animals were necropsied, and brains were formalin-fixed, paraffin- embedded, and sectioned for histological analysis. Tissue sections were mounted on glass slides and stained with hematoxylin and eosin (H&E) to assess tumor morphology, invasion patterns, and pathological features.Reference No.: P2408WO
[0236] Statistical analyses and graphs were performed using GraphPad Prism (USA) and Statas Calculator (source: https: / / astatsa.com) with significance thresholds denoted as follows: **p < 0.05 by χ² test for proportions; #0.05 ≤ p < 0.10 by Gehan-Wilcoxon test (Peto & Peto modification) for survival curves; *p < 0.05 and &0.05 ≤ p < 0.10 by one-tailed t-tests for directional hypotheses.
[0237] Histopathological confirmation at day 7 post-implantation (treatment day 0) revealed small, well demarcated tumors at the injection site, establishing consistent engraftment (Fig.15A). Tumor progression was demonstrated by evaluating the first control animal meeting euthanasia criteria. This animal exhibited classical GBM histopathology - including microvascular proliferation, and frequent mitotic activity with distinct prophase and metaphase figures (Fig. 15B).
[0238] At a 60-day interim analysis, LMP01 demonstrated significant survival extension (Mean survival: 57 days for LMP01 in and 54 days for LMP01 oral+i.n.) versus vehicle controls (Mean survival 46 days) (Table 2, Fig.16). Notably, the intranasal combination regimen showed superior efficacy over oral-intranasal co administration.

It bears a mutation in p53 (TP53) and possible homozygous deletions in the p16 and p14ARF tumor suppressor genes.Reference No.: P2408WO
[0247] LN229 cells were grown using Dulbecco's modified Eagle's medium (DMEM) culture medium (Gibco, USA). Cells were supplied with 10% fetal bovine serum (FBS) (Natocor, Córdoba, AR), 80 μg / mL gentamicin, and 2mM glutamine, in monolayer culture, at 37˚C in a humidified atmosphere of 5% CO2. Cells were harvested using a trypsin / EDTA solution (Thermo Fisher Scientific Inc., USA) diluted in PBS and routinely assessed for mycoplasma. 1. GBM log-phase proliferation
[0248] A high-density log-phase proliferation assay was used to evaluate GBM cellular growth. Briefly, LN229 cells were plated in 96 multi-well plate format at a density of 2 x 10^3 cells per 100 µL of complete DMEM medium. After 24 h, cells were exposed to POH- or DCA- analog compounds. 72 h later exponentially growing cell cultures were fixed for 10 min with methanol and then stained with 0.5% crystal violet solution for another 10 min.
[0249] Following a washing step, fixed cultures were dried overnight. Quantification for the crystal violet method was performed by absorbance measurement (λ=595 nm) after adding an ethanol / acetic acid 3:1 solution. Values are presented as a percentage of control. The tests were performed by duplicate (independent operators), employing 6-12 wells per experimental group per independent replicate. 2. Synergy assessment with selected concentrations
[0250] To assess any possible synergistic effect by combining both POH- and DCA-analogs, different high-density cell proliferation assays were carried out in the exponential phase for 72 h. The potential cooperative effects between drug pairs were evaluated using a combinational matrix design.
[0251] For this purpose, LN229 cells were seeded at a density of 2 x 10^3 cells per well, allowed to attach overnight, and then treated using optimal (IC50) and suboptimal (IC10 and IC25) concentrations of the drugs.
[0252] For subsequent comparative statistical analysis between experimental groups, outlier identification, analysis of combination indexes, dose-response curve shifts, isobolograms, doseReference No.: P2408WO reduction indexes, and synergy scores, the statistical packages PRISM GraphPad, Compusyn, and SynergyFinder were used. 3. Statistics
[0253] In vitro assay determinations were conducted from at least 2 independent experiments. Statistical analyses were mainly performed using GraphPad Prism 8.0V software, (GraphPad Prism Software, USA). Distribution of data and descriptive statistics were firstly assessed. Outliers were detected and removed (Prism calculator).
[0254] For comparisons among 3 or more experimental groups, ANOVA or its non-parametric equivalent, the Kruskal-Wallis test, were utilized, depending on the parametric or non-parametric distribution of values, respectively. Subsequently, tests such as Dunnett's test, Tukey's test, comparison of 95% confidence intervals (CI) for the mean (ANOVA), or Dunn's test (Kruskal- Wallis) were employed.
[0255] Synergy was confirmed when CI<1 or integrated HSA scores>0. For the calculation of the half inhibitory concentration (IC50), nonlinear regressions were applied, based on optimal curve-fitting. Differences were considered statistically significant at a level of p<0.05; *p<0.05; **p<0.01; ***p<0.001; ****p<0.0001.
[0256] The following particular combinations glycolysis inhibitors / modulators and prenyltransferase inhibitors were tested: (1) POH plus metformin HCL (Fig.17, Table 3), (2) POH plus 2DDG (Fig.18, Table 4), (3) DCA plus lonafarnib (Fig.19, Table 5), (4) DCA plus 6-gingerol (Fig.20, Table 6), (5) 2DDG plus lonafarnib (Fig.21, Table 7), (6) 2DDG plus 6-gingerol (Fig.22, Table 8), (7) metformin HCl plus lonafarnib (Fig.23, Table 9), and (8) metformin HCl plus 6-gingerol (Fig.24, Table 10).
[0257] The results showed high synergy (scores >>>0) and combinational indexes <1 for all the combinations of active agents tested, in a dose dependent manner.Reference No.: P2408WO Table 3 Dose POH Dose metformin Effect CI HCl C nism (Table 4 Dose POH Dose 2DDG Effect CI nism, .

[0258] In conclusion, in this interim analysis the evaluation of LMP01 in an orthotopic glioblastoma model demonstrated antitumor efficacy, significantly extending survival compared to vehicle controls. Importantly, the intranasal administration route exhibited superior efficacyReference No.: P2408WO over the oral-intranasal combination, underscoring the impact of delivery optimization on treatment success. These results not only confirm LMP01's antitumor potency but also highlight the critical role of administration route optimization in maximizing therapeutic outcomes.
