[0045] definition Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this disclosure belongs. In carrying out or testing the compositions provided, methods and materials similar or equivalent to those described herein can be used, and suitable methods and materials are described below. Each publication, patent application, patent, and other references mentioned herein are incorporated herein by reference in their entirety. In case of discrepancy, the present specification, including definitions, will take precedence. In addition, materials, methods, and examples are presented for illustrative purposes only and are not intended to be limiting.

[0046] Other features and advantages of the disclosed compositions and methods will become apparent from the following disclosure, drawings, and claims.

[0047] Whenever an embodiment is described herein with the phrase "comprising," it is understood that similar embodiments described with "containing," "consisting of," and / or "consisting essentially of" are also provided. However, when used as transitional clauses in the claims, each should be construed separately and given the appropriate legal and practical content (e.g., in the claims, the transitional clause "comprising" is considered to be more open-ended, while "consisting of" is more exclusive, with "consisting essentially of" being somewhere in between).

[0048] The singular forms "a", "an" and "the" herein include the plural unless specifically stated as singular or unless it is very clear from the context that the plural is not intended. The singular forms "a", "an" and "the" also include the statistical average composition, characteristics or size of particles in a particle population (e.g., the average diameter of liposomes, the average zeta potential of liposomes, the average number of targeting moieties on liposomes in a liposome solution, the average number of encapsulated trans-crocetin molecules). The average particle size and zeta potential of liposomes in a pharmaceutical composition can be routinely measured using methods known in the art (such as dynamic light scattering). The average amount of therapeutic agent in a nanoparticle composition may be routinely measured, for example, using absorption spectroscopy (e.g., UV-Vis spectroscopy).

[0049] When the terms "approximately" and "about" are used herein in relation to one or more target values, these terms refer to values ​​similar to the reference value referred to.In certain embodiments, the term "approximately" or "about" refers to a value range within 25%, within 20%, within 19%, within 18%, within 17%, within 16%, within 15%, within 14%, within 13%, within 12%, within 11%, within 10%, within 9%, within 8%, within 7%, within 6%, within 5%, within 4%, within 3%, within 2%, within 1% or less in either direction (greater or less) of the reference value referred to, unless otherwise stated or the context makes clear otherwise (except when such number exceeds 100% of possible values).For example, when used in relation to the amount of a given compound in the lipid component of nanoparticle composition, "about" can be the average value of the reference value + / - 10%. For example, a nanoparticle composition containing a lipid component that contains about 40% of a given compound may contain 30-50% of the compound.

[0050] As used herein, the term "and / or" in phrases such as "A and / or B" is intended to include both A and B; A or B; A (alone); and B (alone).

[0055] As used herein, the term "encapsulated" refers to the location of a biopolymeric substance (eg, trans-crocetin) surrounded by or contained entirely within a polymer, such as a liposome.

[0056] The term "liposome" refers to a closed vesicle with an internal phase (i.e., an internal space (internal solution)) surrounded by a lipid bilayer. Liposomes can be small unilamellar liposomes such as small unilamellar vesicles (SUVs), large unilamellar liposomes such as large unilamellar vesicles (LUVs), larger unilamellar liposomes such as giant unilamellar vesicles (GUVs), multilamellar liposomes with multiple concentric membranes such as multilamellar vesicles (MLVs) (e.g., bilayer, trilayer, tetralayer, pentalayer, hexalayer, octaplayer, 9layer, or 10layer), or irregular, non-concentric membranes such as multivesicular vesicles (MVVs).

The solution of the liposome's internal phase is referred to as the "internal solution." In contrast, the term "external phase of a liposome" refers to the region not surrounded by the lipid bilayer of the liposome, such as the internal phase and regions distant from the lipid bilayer when the liposome is dispersed in a liquid.

[0059] The term "counterion" refers to an anionic or cationic counterion.

[0060] "Cationic counterion" refers to a positively charged atom or group that associates with an anionic atom or group to maintain electrical neutrality. Examples of cationic counterions include inorganic cations (e.g., metal cations (e.g., alkali metal cations, alkaline earth metal cations, and transition metal cations)) and organic cations (e.g., ammonium cations, sulfonium cations, phosphonium cations, and pyridinium cations). "Anionic counterion" refers to a negatively charged atom or group that associates with a cationic atom or group to maintain electrical neutrality. Examples of anionic counterions include halide anions (e.g., F - , Cl - , Br - , and I - ), NO 3- , ClO 4- , O.H. - , H2PO4 2- , HSO 4- , sulfonate anions (e.g., methanesulfonate, trifluoromethanesulfonate, p-toluenesulfonate, benzenesulfonate, 10-camphorsulfonate, naphthalene-2-sulfonate, naphthalene-1-sulfonic acid-5-sulfonate, ethane-1-sulfonic acid-2-sulfonate, etc.), and carboxylate anions (e.g., acetate, ethanoate, propanoate, benzoate, glycerate, lactate, tartrate, and glycolate). The counter ion can be monovalent or polyvalent (e.g., divalent, trivalent, tetravalent, etc.).

[0061] The term "ionizable" refers to a compound that contains at least one functional group that (a) has a positive or negative charge (i.e., is "ionized") and is therefore associated with a counterion of opposite charge, or (b) is electrically neutral but ionizes at higher or lower pH. Thus, ionizable compounds include quaternary ammonium salts and uncharged amines, and carboxylic acid moieties and uncharged carboxyl groups.

[0062] The term "natural" refers to a compound or composition that is naturally occurring, whether isolated from a natural source or chemically synthesized. Examples of naturally occurring carotenoid mono- and dicarboxylic acids include crocetin, norbixin, azafrin, and crassa-bioxanthin.

[0063] "Effective amount" herein refers to a drug dosage sufficient to give a medically desired result. Effective amounts vary depending on the desired result, the particular disease or condition being treated or prevented, the age and physical condition of the subject being treated, the severity of the condition, the duration of treatment, the nature of concurrent or combined therapy (if implemented), the particular route of administration, and factors within the knowledge and expertise of medical health professionals. "Effective amount" can be determined empirically in the usual manner in relation to the stated purpose.

[0064] In the case of pulmonary diseases such as ARDS, COPD, sepsis or lung inflammation, an effective amount of an agent may be one that stabilizes or improves lung function, as indicated, for example, by an improvement in pAO2 / FiO2 ratio (an increase in P / F ratio, e.g., at least 15%, 20%, 25%, PaO2 / FiO2 ratio, or an increase in PaO2 / FiO2 ratio to greater than 200 mmHg within 24 hours of administration), normalization of physical exam and respiratory rate, normalization of pCO2 preventing the need for intubation and mechanical ventilation, (for those on mechanical ventilation) a reduction in the number of days on the ventilator, a reduction in the length of hospital stay, a reduction in the number of days in intensive care, or a combination thereof.

[0065] In the case of cancer, an effective amount of an agent may, for example, reduce the number of cancer cells; reduce tumor size; inhibit (i.e., slow to some extent, and preferably stop) cancer cell invasion into peripheral organs; inhibit (i.e., slow to some extent, and preferably stop) tumor metastasis; inhibit (i.e., slow to some extent, and preferably stop) tumor growth; and / or alleviate to some extent one or more of the symptoms associated with the disorder. To the extent that the agent may prevent the growth of existing cancer cells and / or kill existing cancer cells, the agent may be cytostatic and / or cytotoxic (toxic). For cancer therapy, in vivo efficacy may be evaluated, for example, by evaluating survival time, progression-free survival (PFS), response rate (RR), duration of response, and / or quality of life.

[0066] The phrase "subject in need thereof" as used herein refers to a subject (e.g., a human or non-human mammal) that exhibits one or more symptoms or signs of aging and / or a chronic disease, or that has been determined to have one or more symptoms or signs of aging and / or a chronic disease, and therefore is in need of a particular therapy. In some embodiments, the diagnosis can be any diagnostic means. In any of the methods and treatment regimens described herein, the subject can be in need thereof. In some embodiments, the term "subject in need thereof" includes patients who, for example, exhibit (or have exhibited) one or more symptoms of an age-related disease or condition, and / or patients who exhibit aging biomarkers and / or SASP, prior to treatment. In some embodiments, the term "subject in need thereof" includes patients who, for example, exhibit (or have exhibited) one or more symptoms of a chronic disease or condition, and / or patients who exhibit chronic disease biomarkers, prior to treatment.

[0067] The terms "hyperproliferative disorder", "proliferative disease" and "proliferative disorder" are used herein as synonyms relating to unwanted or uncontrolled cell proliferation of undesirable excess or abnormal cells, such as neoplastic or hypertrophic growth, whether in vitro or in vivo. In some embodiments, the proliferative disease is a cancer or neoplastic disease (including benign or cancerous) and / or any metastasis, although the cancer, tumor and / or metastasis may be located at any site. In some embodiments, the proliferative disease is a benign or malignant tumor. In some embodiments, the proliferative disease is a non-cancerous disease. In some embodiments, the proliferative disease is a hyperproliferative condition such as hyperplasia, fibrosis (particularly pulmonary, but also including other types of fibrosis, such as renal fibrosis), angiogenesis, psoriasis, atherosclerosis and proliferation of vascular smooth muscle (such as stenosis or restenosis after angioplasty).

[0068] "Cancer," "tumor," or "malignant tumor" are used synonymously to refer to a number of disorders characterized by the uncontrolled abnormal growth of cells, the ability of diseased cells to spread locally or via the bloodstream and lymphatic system to other parts of the body (metastasize), and any of a number of characteristic structural and / or molecular properties. "Tumor" herein refers to all neoplastic cell growth and spread, whether malignant or benign, and all pre-cancerous and cancerous cells and tissues. A "cancerous tumor" or "malignant cell" is understood to be a cell that is undifferentiated and has certain structural characteristics capable of invasion and metastasis. Cancers treatable with the liposomal trans-crocetin compositions and / or administration regimens provided herein include, but are not limited to, lung cancer, pancreatic cancer, breast cancer, ovarian cancer, prostate cancer, head and neck cancer, gastric cancer, cancer of the digestive tract, colorectal cancer, esophageal cancer, cervical cancer, liver cancer, kidney cancer, bile duct cancer, gallbladder cancer, bladder cancer, sarcoma (e.g., osteosarcoma), brain cancer, cancer of the central nervous system, and non-hematopoietic malignancies such as melanoma; malignant hematological diseases such as leukemia, lymphoma and other B-cell malignancies, myeloma and other plasma cell dysplasias, or cachexia. Other types of cancers and tumors that may be treated with the trans-crocetin compositions are described herein or known in the art. The terms "cancer," "cancerous," "cell proliferative disorder," "proliferative disease," and "tumor" are not mutually exclusive when referred to herein.

[0069] "Ischemia" refers to the restriction of blood supply to tissue or organ (tissue hypoperfusion), which causes a lack of oxygen required for cellular metabolism. The term "ischemic injury" herein refers to damage caused by the lack of oxygen required for cellular metabolism and to pathologies associated with ischemia, including ischemic stroke, peripheral vascular disease, cerebrovascular disease, kidney disease and renal pathology associated with ischemia, reperfusion, reperfusion injury, wound-associated ischemia, tissue hypoperfusion, ischemic reperfusion injury, transient cerebral ischemia, cerebral ischemia reperfusion, ischemic stroke, hemorrhagic stroke, traumatic brain injury, These include, but are not limited to, gastrointestinal ischemia, pulmonary embolism, acute respiratory failure, neonatal respiratory distress syndrome, obstetric emergencies to reduce perinatal comorbidities (such as conditions leading to preeclampsia and cerebral palsy), myocardial infarction, acute limb or mesenteric ischemia, coronary artery disease, cardiac cirrhosis, chronic congestive heart failure, atherosclerotic stenosis, anemia, thrombosis, embolism, or migraine (e.g., chronic migraine or severe migraine disorder).

[0070] Organ "impairment" or "failure" refers to a pathological condition in which a particular organ does not perform its expected function. When normal homeostasis cannot be maintained without external clinical intervention, organ dysfunction progresses to organ failure. Methods for determining organ dysfunction are known in the art and include, but are not limited to, monitors and scores, including sequential organ dysfunction assessment score (SOFA), multiple organ dysfunction (MOD) score, and logistic organ dysfunction (LOD) score.

[0071] The terms "treating" or "treatment" or "to treat" and the like refer to both (a) therapeutic measures that cure, slow, attenuate, alleviate symptoms of a diagnosed pathological disorder or condition, and / or halt the progression of the disorder or condition, and (b) prophylactic or preventative measures that prevent and / or slow the onset of the target disorder or condition. Desired therapeutic effects include, but are not limited to, prevention of the onset or recurrence of aging and / or chronic disease, alleviation of symptoms associated with the disorder or condition, reduction of the direct or indirect pathological effects of the disorder or condition, prevention of metastasis, slowing the rate of progression of the disorder or condition, recovery from or alleviation of aging and / or chronic disease, and / or improved or improved prognosis. Thus, subjects in need of treatment include, for example, subjects already suffering from a chronic disease, subjects at risk of a chronic disease, and subjects in whom chronic disease prevention is to be performed. A subject is determined to be "suffering or at risk of suffering from" a chronic disease, for example, using well-known medical and diagnostic techniques. In certain embodiments, a subject is successfully "treated" according to the methods provided herein, for example, if the subject shows complete, partial, or transient improvement or disappearance of symptoms associated with the disease or condition (e.g., aging and / or chronic disease). Treatment can be with the disclosed pharmaceutical composition provided herein (e.g., liposomal trans-crocetin salt) alone or in combination with additional therapeutic agents.

[0072] The terms "subject" and "patient" and "animal" are used synonymously and refer to mammals, such as human patients and non-human primates, as well as experimental animals, such as rabbits, rats, and mice, and other animals. Animals include all vertebrates, for example, mammals and non-mammals, such as chickens, amphibians, and reptiles. "Mammal" herein refers to any member of the class Mammalia, including, but not limited to, human and non-human primates, such as chimpanzees and other ape and monkey species; domestic animals, such as cows, sheep, pigs, goats, and horses; domestic mammals, such as dogs and cats; laboratory animals, including rodents, such as mice, rats, and guinea pigs, and other members of the class Mammalia known in the art. In a particular embodiment, the patient is a human.

[0073] The term "elderly" refers to an elderly subject that has passed middle age. In one embodiment, an elderly mammalian subject is a subject that has lived for more than two-thirds of the normal life span of that mammalian species. In a further embodiment, for humans, the elderly or elderly subject is over 65 years old (e.g., a subject over 70 years old, over 75 years old, over 80 years old, etc.). In yet another embodiment, for mice, the elderly mouse is about 14 months old to about 18 months old.

[0074] A "fixed" or "uniform" dose or "fixed dose administration" or "uniform dose administration" of a therapeutic agent (such as trans-crocetin and / or other therapeutic agent) refers to a dose administered to a subject, such as a human patient, regardless of the subject patient's body weight (WT) or body surface area (BSA). Thus, the fixed or uniform dose is not expressed in mg / kg dose or mg / m dose, but rather in absolute amounts of liposomal trans-crocetin and / or other therapeutic agent.

[0075] In some embodiments, the fixed dose administration regimen can be stratified into two or more fixed doses based on the patient's body weight, body mass, age, sex, frame size, height, general health, or any combination thereof, or regardless of age, height, sex, frame size, general health. For example, the fixed dose can be stratified into multiple (e.g., three) fixed doses suitable for subjects in weight categories, such as low weight, normal weight, or high weight subjects. In one embodiment, the fixed doses are stratified based on body weight: low weight (e.g., 100 pounds or less), normal weight (e.g., 100-190 pounds), and high weight (e.g., 190 pounds or more) categories. In another embodiment, the fixed doses are stratified based on age and sex categories: children under 12 years old, boys aged 10-15 years old, and women over 12 years old, and men over 15 years old. Those skilled in the art can evaluate factors related to body weight and assign subjects to specific weight categories.

[0076] "Loading dose" refers to the amount of therapeutic agent, such as trans-crocetin (e.g., liposomal trans-crocetin, free trans-crocetin, conjugated / complexed trans-crocetin, or a combination thereof), administered to a subject at an early stage of treatment. The loading dose of trans-crocetin may be fixed or non-fixed. The purpose of the loading dose is to allow the subject to reach a therapeutic level of the therapeutic agent more quickly than with maintenance dosing alone. Furthermore, the loading dose allows the therapeutic agent (e.g., trans-crocetin) to reach a sufficient level to be able to switch to maintenance dosing and maintain the therapeutic level. Furthermore, the loading dose allows the therapeutic agent to reach a relatively constant therapeutic level to reach a steady state. The steady state of the therapeutic agent can be considered as a state in which the total intake of the therapeutic agent is in dynamic equilibrium with its excretion. Once the therapeutic agent reaches a therapeutic level, the loading dose is followed by multiple fixed maintenance doses. By increasing the loading dose concentration, the time interval between loading doses can be extended.

[0077] "Maintenance dose" refers to the amount of a therapeutic agent, such as liposomal trans-crocetin, administered to a subject throughout a treatment period to maintain a therapeutic level of the therapeutic agent in the subject. Such a therapeutic level of a therapeutic agent is more quickly achieved and maintained by administering one or more loading doses, as described herein, to the subject prior to administration of the maintenance dose. Typically, the maintenance dose is administered repeatedly at spaced treatment intervals. In some embodiments, the maintenance dose of trans-crocetin is administered to the subject once a day, twice a week, once a week, four times a month, three times a month, twice a month, or once a month. In some embodiments, the maintenance dose of trans-crocetin is administered to the subject four times a month, three times a month, twice a month, or once a month.

[0078] The term "pharmaceutical acceptable carrier" refers to an ingredient other than the active ingredient in a pharmaceutical formulation that is non-toxic to a subject. Pharmaceutically acceptable carriers include, but are not limited to, buffers, carriers, additives, stabilizers, diluents, or preservatives. Pharmaceutically acceptable carriers can include, for example, one or more compatible solid or liquid fillers, diluents, or encapsulating substances that are suitable for administration to humans or other subjects.

[0079] The term "therapeutic agent" in the broadest sense herein includes any agent capable of providing a desired or beneficial effect in a subject. Thus, the term includes both preventative and therapeutic agents, as well as any other category of agents that have such a desired effect. The therapeutic agent or agents used in combination therapy with trans-crocetin according to the compositions and methods of the present disclosure may include agents intended to treat a disease state in a subject.

[0080] The term "kit" refers to a set of one or more components required to use the methods and compositions provided herein, including, but not limited to, trans-crocetin compositions, including liposomal trans-crocetin, cyclodextrin-trans-crocetin formulations, and free trans-crocetin formulations disclosed herein, reagents, buffers, containers, and / or equipment.

[0081] The term "radiosensitizer" refers to a compound that makes tumor cells more sensitive to radiation therapy. Examples of radiosensitizers include misonidazole, metronidazole, tirapazamine, and trans-crocetin.

In some embodiments, the liposomal trans-crocetin composition administered does not include a fixed dose of liposomal trans-crocetin.

[0088] In some embodiments, the present disclosure provides pharmaceutical compositions comprising trans-crocetin calcium (CTC). The CTC can exist in linear and / or cyclic forms (shown below): [ka] Also provided herein are liposomes comprising the CTC compositions and pharmaceutical compositions (e.g., liposomal compositions) comprising the liposomes. In some embodiments, the pharmaceutical composition administered according to the provided methods is a fixed dose of liposomal CTC. In some embodiments, the liposomal trans-crocetin composition administered does not include a fixed dose of liposomal CTC.

In some embodiments, the pharmaceutical composition administered according to the provided methods is a fixed dose of liposomal MTC. In some embodiments, the liposomal trans-crocetin composition administered does not include a fixed dose of liposomal MTC.

[0090] Lipids and other components of the liposomes included in the liposome composition can be any lipid, any combination and ratio of lipids, or combination of lipids and other liposome components and their respective ratios known in the art. However, one skilled in the art will understand that liposomal encapsulation of any particular agent, such as but not limited to the trans-crocetin compositions discussed herein, may involve substantial routine experimentation to create a useful and functional liposomal formulation. In general, the provided liposomes may have any liposomal structure, including structures with an interior space separated from the outside medium by one or more lipid bilayers, or any microcapsule with a semipermeable membrane with a lipophilic core that separates the membrane from the interior. The lipid bilayer can be any arrangement of amphiphilic molecules characterized by hydrophilic and hydrophobic portions. Typically, the amphiphilic molecules in the bilayer are arranged in a two-dimensional sheet with the hydrophobic portions facing inward of the sheet, while the hydrophilic portions facing outward. The amphiphilic molecules forming the provided liposomes can be any known or yet to be discovered amphiphilic molecules, such as lipids or biocompatible lipids of synthetic or natural origin. The liposomes can also be formed by amphiphilic polymers and surfactants, such as polymerosomes and niosomes. For purposes of this disclosure, but without limitation, these liposome-forming materials are also referred to as "lipids."

[0091] The liposome composition formulations provided herein may be in liquid form or in dry form, such as dry powder or dry solid. The dry powder or dry solid may be, for example, first dried under lyophilization conditions, or optionally, the dry solid or dry powder may be only first dried twice, or may be both first and second dried. In the dry form, the powder or solid may have, for example, 1% to 6% moisture (e.g., 2% to 5% moisture or 2% to 4% moisture, etc.). An example of a drying method is lyophilization (also called freeze-drying or cryodessication). Any of the compositions and methods of the present disclosure may include liposomes, lyophilized liposomes, or liposomes reconstituted from lyophilized liposomes. In some embodiments, the compositions and methods include one or more lyoprotectants or cryoprotectants. These protectants are typically sugars (monosaccharides, disaccharides, and polysaccharides), polyalcohols and their derivatives, glycerol, or polyhydroxy compounds such as polyethylene glycol, trehalose, maltose, sucrose, glucose, lactose, dextran, glycerol, or aminoglycosides. In further embodiments, the lyoprotectants or cryoprotectants comprise up to 10% or up to 20% of the solution outside the liposome, inside the liposome, or both outside and inside the liposome.

[0092] The properties of liposomes are influenced by the nature of the lipids used to prepare the liposomes. A variety of lipids have been used to prepare liposomes. Such lipids include cationic, anionic, and neutral lipids. In some embodiments, the liposomes containing the trans-crocetin compositions (e.g., CTC and MTC) are anionic or neutral. In other embodiments, the liposomes provided are cationic. The charge (e.g., anionic, neutral, or cationic) can be determined by routine methods by measuring the zeta potential of the liposomes. The zeta potential of the liposomes can be positive, zero, or negative. In some embodiments, the zeta potential of the liposomes is -150 to 150 mV, or -50 to 50 mV, or any range therebetween. In some embodiments, the zeta potential of the liposomes is equal to or less than zero. In some embodiments, the zeta potential of the liposome is -150 to 0, -50 to 0 mV, -40 to 0 mV, -30 to 0 mV, -25 to 0 mV, -20 to 0 mV, -10 to 0 mV, -9 to 0 mV, -8 to 0 mV, -7 to 0 mV, -6 to 0 mV, -5 to 0 mV, -4 to 0 mV, -3 to 0 mV, -2 to 0 mV, -1 to 0 mV, or -8 to 2 mV, or any range therebetween. In other embodiments, the zeta potential of the liposome is higher than zero. In some embodiments, the zeta potential of the liposome is 0.2 to 150 mV, 1 to 50 mV, 1 to 40 mV, 1 to 30 mV, 1 to 25 mV, 1 to 20 mV, 1 to 15 mV, 1 to 10 mV, 1 to 5 mV, 2 to 10 mV, 3 to 10 mV, 4 to 10 mV, or 5 to 10 mV, or any range therebetween.

[0093] The particle size (diameter) of the liposomes can be controlled depending on the desired application. For example, when the liposomes as an injectable product are intended to be delivered to cancerous or inflamed tissues by the enhanced vascular permeability / retention (EPR) effect, the liposome diameter is preferably in the range of 20 to 500 nm, 30 to 175 nm, or 50 to 150 nm, or any range therebetween. When the liposomes are intended to be delivered to macrophages, the liposome diameter is preferably in the range of 30 to 1000 nm, or 80 to 400 nm, or any range therebetween. When the liposome composition is intended to be used as an oral preparation or a transdermal preparation, the particle size of the liposomes can be set to several microns. It should be noted that in normal tissues, the vascular wall acts as a barrier (the reason for this is that the vascular wall is densely composed of vascular endothelial cells), and macromolecules of a certain size and microparticles such as liposomes cannot be distributed in the tissue. However, in diseased tissues, the blood vessel walls are loose (because they have gaps between the endothelial cells), which increases vascular permeability and allows macromolecules and microparticles to distribute to extravascular tissues (enhanced permeability).Furthermore, it is known that while the lymphatic system is well developed in normal tissues, in diseased tissues the lymphatic system is not developed, and once taken up, macromolecules or microparticles are not recirculated by the general system and remain in the diseased tissue (prolonged retention), which is the basis of the EPR effect (Wang et al., Ann. Rev. Med. 63:185-198 (2012); Peer et al., Nat. Nanotech. 2:751-760 (2007); Exp. Opin. Drug Deliv. 8:565-580 (2011); Huwyler et al., Int. J. Nanomed. 3:21-29 (2008); Maruyama et al., Adv. Drug Deliv. Rev. 63:161-169 (2011); Musacchio and Torchilin, Front. Biosci. 16:1388-1412). (2011); Baryshnikov, Vest. Ross. Akad. Med. Nauk. 23-31 (2012); and Torchilin, Nat. Rev. Drug Disc. 4:145-160 (2005)). Thus, it is possible to control liposome pharmacokinetics by adjusting the liposome particle size (diameter).

[0094] In some embodiments, cationic lipids are used to create cationic liposomes, which are commonly used as gene transforming agents. The positive charges on the cationic liposomes allow them to interact with the negative charges on the cell surface. After the cationic liposomes bind to the cells, the liposomes are transported into the cell interior by endocytosis.

[0095] In some preferred embodiments, neutral to anionic liposomes are used. In one preferred embodiment, anionic liposomes are used. For example, by using a mixture of neutral lipids such as HSPC and anionic lipids such as PEG-DSPE, anionic liposomes are formed that are less likely to bind nonspecifically to normal cells. Specific binding to tumor cells can be achieved by using tumor-targeting antibodies, such as folate receptor antibodies (including, for example, folate receptor alpha antibodies, folate receptor beta antibodies, and / or folate receptor delta antibodies).

[0096] As an example, at least one (or more) of the lipids are amphipathic lipids, defined as having a hydrophilic portion and a hydrophobic portion (typically a hydrophilic head and a hydrophobic tail). The hydrophobic portion typically orients toward the hydrophobic phase (e.g., within the bilayer), while the hydrophilic portion typically orients toward the aqueous phase (e.g., outside the bilayer). The hydrophilic portion may contain polar or charged groups (such as carbohydrate, phosphate, carboxyl, sulfate, amino, sulfhydryl, nitro, hydroxy, and other similar groups). The hydrophobic portion may contain non-polar groups; such groups include, but are not limited to, long chain saturated and unsaturated aliphatic hydrocarbon groups and groups substituted with one or more aromatic, alicyclic, or heterocyclic groups. Examples of amphipathic compounds include, but are not limited to, phospholipids, aminolipids, and sphingolipids.

[0097] Typically, for example, the lipids are phospholipids, including, but not limited to, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylserine, etc. It is understood that other lipid membrane components, such as cholesterol, sphingomyelin, and cardiolipin, may be used.

[0098] The lipids comprising the liposomes provided herein can be anionic and neutral (including zwitterionic and polar) lipids, including anionic and neutral phospholipids. Neutral lipids exist in uncharged or neutral zwitterionic form at selected pH. At physiological pH, such lipids include, for example, dioleoylphosphatidylglycerol (DOPG), diacylphosphatidylcholine, diacylphosphatidylethanolamine, ceramide, sphingomyelin, cephalin, cholesterol, cerebrosides and diacylglycerols. Examples of zwitterionic lipids include, but are not limited to, dioleoylphosphatidylcholine (DOPC), dimyristoylphosphatidylcholine (DMPC) and dioleoylphosphatidylserine (DOPS).

[0102] In one embodiment, the lipid may be a cleavable lipid, such as those described in International Patent Application WO2012 / 170889; this reference is incorporated herein by reference in its entirety.

[0103] The cationic lipids can be synthesized in a conventional manner using methods known in the art (see, e.g., International Patent Applications WO2012 / 040184, WO2011 / 153120, WO2011 / 149733, WO2011 / 090965, WO201 / 1043913, WO2011 / 022460, WO2012 / 061259, WO2012 / 054365, WO2012 / 044638, WO2010 / 080724, and WO2010 / 21865; each of these references is incorporated herein by reference in its entirety.

[0104] The lipid derivatives may, for example, include at least one or more steric stabilizers and / or functional groups attached (preferably covalently) to the liposome components, which should be considered as part of the liposome components after attachment. The functional groups include groups that can be used to link the liposome components to other moieties, such as proteins. Such functional groups include at least maleimide.

[0108] In some embodiments, the liposomes of the liposome composition of the present disclosure contain oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine (OxPAPC). The term "oxPAPC" herein refers to lipids produced by oxidation of 1-palmitoyl-2-arachidonyl-sn-glycero-3-phosphorylcholine (PAPC), which results in a mixture of oxidized phospholipids containing either fragmented or full-length oxygenated sn-2 residues. The oxidative fragmentation species that have been well characterized contain 5-carbon sn-2 residues with omega-aldehyde or omega-carboxyl groups. Oxidation of arachidonic acid residues also produces phospholipids containing esterified isoprostanes. Other oxidation products of oxPAPC include HOdiA-PC, KOdiA-PC, HOOA-PC and KOOA-PC species. In further embodiments, the oxPAPCs are epoxyisoprostane-containing phospholipids. In further embodiments, the oxPAPC is 1-palmitoyl-2-(5,6-epoxyisoprostane E2)-sn-glycero-3-phosphocholine (5,6-PEIPC), 1-palmitoyl-2-(epoxy-cyclopentenone)-sn-glycero-3-phosphoryl-choline (PECPC) and / or 1-palmitoyl-2-(epoxy-isoprostane E2)-sn-glycero-4-phosphocholine (PEIPC). In some embodiments, the phospholipids have unsaturated bonds. In some embodiments, the phospholipids are arachidonic acid containing phospholipids. In another embodiment, the phospholipids are in sn-2-oxygenated form. In another embodiment, the phospholipids are in unfragmented form.

In further embodiments, the liposome comprises PGPC.

[0110] In some embodiments, at least one component of the liposomal lipid bilayer is functionalized or reactive. A functionalized component herein is a component that contains a reactive group that can be used to crosslink reagents and moieties to the lipid. If the lipid is functionalized, the liposome composed of the lipid is also functionalized. In some embodiments, the reactive group is a reactive group that reacts with a crosslinker (or other moiety) to form a crosslink. The reactive group in the liposomal lipid bilayer is located at any site on the lipid that is accessible to a crosslinker and that can be crosslinked to another moiety (e.g., a steric stabilizer or a targeting moiety). In some embodiments, the reactive group is present in the head group of the lipid, including, for example, a phospholipid. In some embodiments, the reactive group is a maleimide group. Maleimide groups can be crosslinked to each other in the presence of a dithiol crosslinker; such dithiol crosslinkers include, but are not limited to, dithiothreitol (DTT).

[0111] It should be understood that the use of other functionalized lipids, other reactive groups, and other crosslinkers beyond those mentioned above is also contemplated. In addition to maleimide groups, other examples of contemplated reactive groups include, but are not limited to, amino groups, such as primary and secondary amines, carboxyl groups, hydroxyl groups, aldehyde groups, alkyne groups, azide groups, carbonyls, haloacetyl groups (e.g., iodoacetyl), imidoester groups, N-hydroxysuccinimide esters, sulfhydryl groups, and other thiol-reactive groups, such as pyridyl disulfide groups, among others.

[0112] Functionalized and non-functionalized lipids are available from several commercial sources, including Avanti Polar Lipids (Alabaster, Alabama) and Lipoid LLC (Newark, NJ).

[0113] In some embodiments, the liposomes contain steric stabilizers that extend their residence time in the blood circulation. One or more steric stabilizers, such as hydrophilic polymers (polyethylene glycol (PEG)), glycolipids (monosialoganglioside (GM1)), occupy the space immediately adjacent to the liposome surface and exclude other macromolecules from this space. This prevents the proximity and binding of plasma opsonins to the liposome surface, inhibiting such liposome-macrophage interactions and any other clearance mechanisms, thereby extending the residence time of the liposomes in the blood circulation. In some embodiments, the steric stabilizer or steric stabilizers are PEG or a combination comprising PEG. In further embodiments, the steric stabilizer is PEG or a combination comprising PEG with a number average molecular weight (Mn) of 200-5000 Daltons. These PEGs can be of any structure, such as linear, branched, star-shaped, or comb-shaped structures; and are commercially available.

[0124] The liposomes provided include an aqueous compartment surrounded by at least one type of lipid bilayer. When lipids containing hydrophilic head groups are dispersed in water, they spontaneously form a bilayer membrane called a lamella. The lamella is composed of two monolayer sheets of lipid molecules, with the sheets having a non-polar (hydrophobic) surface facing each other and a polar (hydrophilic) surface facing the aqueous medium. The term "liposome" includes unilamellar vesicles that are composed of a single lipid bilayer and generally have a diameter of about 20 to about 500 nm, about 50 to about 300 nm, about 50 to about 150 nm, about 30 to about 1000 nm, about 30 to about 175 nm, about 80 to about 400 nm, or about 80 to about 120 nm.

In some embodiments, the trans-crocetin concentration is 0.5, 1, 2, 2.5, 3, 3.5, 4, 4.5 or 5 mg / ml.

[0169] In a further embodiment, the conjugating / complexing agent is a cyclodextrin. There is no particular limitation on the cyclodextrin contained in the provided pharmaceutical composition, so long as the cyclodextrin can be complexed with trans-crocetin.

[0170] In certain embodiments, the cyclodextrin of the pharmaceutical composition is underivatized.

[0171] In other specific embodiments, the cyclodextrin is derivatized to contain ionizable (eg, weakly basic and / or weakly acidic) functional groups to facilitate complexation with trans-crocetin.

[0172] Modification of cyclodextrin hydroxyl groups, such as modification with ionizable chemical groups that orient the cyclodextrin away from the internal phase, is known to facilitate loading of cyclodextrins and therapeutic agents complexed with cyclodextrins. In some embodiments, the cyclodextrin in the pharmaceutical composition has at least 2, 3, 4, 5, 6, 6, 7, 8, 9, or 10 hydroxyl groups substituted with ionizable chemical groups. The term "charged cyclodextrin" refers to a cyclodextrin in which one or more of its hydroxyl groups have been substituted with a charged moiety. Such moieties may themselves be charged groups; or may include an organic moiety (e.g., a C1-C6 alkyl or C1-C6 alkyl ether moiety) substituted with one or more charged moieties.

[0173] In some embodiments, the "ionized" or "charged" moieties of the cyclodextrin derivatives in the pharmaceutical compositions are weakly ionizable. Weakly ionizable moieties are either weakly basic or weakly acidic moieties. The pKa of the weakly basic functional group (W) is about 6.0-9.0, 6.5-8.5, 7.0-8.0, 7.5-8.0, and any range therebetween for CH3-W. Similarly, the log dissociation constant (pKa) of the weakly acidic functional group (X) is about 3.0-7.0, 4.0-6.5, 4.5-6.5, 5.0-6.0, 5.0-5.5, and any range therebetween for CH3-X. Representative anionic moieties include, but are not limited to, carboxylate, carboxymethyl, succinyl, sulfonyl, phosphate, sulfoalkyl ether, sulfate carbonate, thiocarbonate, dithiocarbonate, phosphate, phosphonate, sulfonate, nitrate, and borate groups. Representative cationic moieties include, but are not limited to, amino, guanidine, and quaternary ammonium groups.

[0174] In another embodiment, the pharmaceutical composition comprises a derivatized cyclodextrin that is a "polyanion" or a "polycation." A polyanion is a derivatized cyclodextrin that has two or more negatively charged groups, thereby resulting in three or more units of net negative ionic charge. A polycation is a derivatized cyclodextrin that has two or more positively charged groups, thereby resulting in three or more units of net positive ionic charge.

[0175] In another embodiment, the pharmaceutical composition comprises a derivatized cyclodextrin that is a "chargeable amphiphile." "Chargeable" means that the amphiphile has a pK between pH 4 and pH 8 or 8.5. Thus, a chargeable amphiphile can be a weak acid or a weak alkali. As used herein, "amphoteric" refers to a derivatized cyclodextrin that has ionizable groups that are both anionic and cationic in nature, where: (a) at least one, and optionally both, of the cationic and anionic amphiphiles are chargeable and have at least one charged group with a pK of 4 to 8 to 8.5; (b) at pH 4 the cationic charge predominates; and (c) At pH 8 to 8.5, the anionic charge predominates.

[0176] In some embodiments, the "ionized" or "charged" derivatized cyclodextrin, whether polyionic, amphiphilic, or otherwise, is overall weakly ionizable (i.e., has a pKai of about 4.0-8.5, 4.5-8.0, 5.0-7.5, 5.5-7.0, 6.0-6.5, and any range therein).

[0177] Any one, multiple, or all of the hydroxyl groups in any one, multiple, or all of the α-D-glucopyranoside units of the cyclodextrin may be modified with an ionizable chemical group as described herein. Because each cyclodextrin hydroxyl group has a different chemical reactivity, reaction with the modifying moiety may produce an indefinite mixture of positional and optical isomers. Alternatively, the α-D-glucopyranoside units can be pre-modified with a specific chemistry in order to react to produce a homogenous product.

[0178] The total amount of substitution for the cyclodextrin derivatives in a mixture is expressed in terms of degree of substitution. For example, 6-ethylenediamino-β-cyclodextrin with a degree of substitution of 7 is composed of an isomeric distribution of 6-ethylenediamino-β-cyclodextrins in which the average number of ethylenediamino groups per 6-ethylenediamino-β-cyclodextrin molecule is 7. The degree of substitution for a mixture of cyclodextrin derivatives can be determined by conventional methods using mass spectrometry or nuclear magnetic resonance spectroscopy.

[0179] In one embodiment, at least one hydroxyl moiety oriented away from the interior of the cyclodextrin is substituted with an ionizable chemical group. For example, the C2, C3, C6, C2 and C3, C2 and C6, C3 and C6, and all three C2-C3-C6 hydroxyls of at least one α-D-glucopyranoside unit are substituted with an ionizable chemical group. Any such combination of hydroxyl groups can be combined with at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and up to all α-D-glucopyranoside units in the modified cyclodextrin, and can be combined with any degree of substitution as set forth herein. One such derivative is sulfoalkyl ether cyclodextrin (SAE-CD). Sulfobutyl ether derivatives of beta-cyclodextrin (SBE-β-CD) have been demonstrated to have significantly improved aqueous solubility compared to the parent cyclodextrin.

[0180] Further cyclodextrin derivatives that can be complexed with trans-crocetin in the provided pharmaceutical compositions include sugammadex or Org25969, in which the 6-hydroxy group of γ-CD is replaced with a carboxythioacetate ether bond and hydroxybutenyl-β-CD.

[0181] In some embodiments, a high binding constant between the cyclodextrin and trans-crocetin is preferred, and can be obtained by selecting the number of glucose units in the cyclodextrin based on the size of the therapeutic agent (see, e.g., Albers et al., Crit. Rev. Therap. Drug Carrier Syst. 12:311-337 (1995); Stella et al., Toxicol. Pathol. 36:30-42 (2008)). If the binding constant is pH-dependent, the cyclodextrin can be selected so that the binding constant is high at the pH of the composition. As a result, the solubility (nominal solubility) of the liposomal trans-crocetin in the presence of cyclodextrin can be further improved. In some embodiments, the binding constant of cyclodextrin to trans-crocetin is 100, 200, 300, 400, 500, 600, 700, 800, 900, 1,000 or more.
