Description

[Technical field]

[0001] The present disclosure relates to dosing regimens and combinations comprising N-[4-(chlorodifluoromethoxy)phenyl]-6-[(3R)-3-hydroxypyrrolidin-1-yl]-5-(1H-pyrazol-5-yl)pyridine-3-carboxamide or a pharma- ceutically acceptable salt thereof, and their use for the treatment of diseases or disorders mediated by the breakpoint cluster region-Abelson protein (BCR-ABL). [Background technology]

[0002] The tyrosine kinase activity of the ABL1 protein is normally tightly regulated, with the N-terminal cap region of the SH3 domain playing a key role. One regulatory mechanism involves the glycine-2 residue of the N-terminal cap being myristoylated and then interacting with a myristic acid-binding site in the SH1 catalytic domain. A distinctive feature of chronic myeloid leukemia (CML) is the Philadelphia chromosome (Ph), formed by a reciprocal chromosomal translocation of t(9,22) in hematopoietic stem cells. This chromosome harbors the BCR-ABL1 oncogene, encoding a chimeric BCR-ABL1 protein lacking the N-terminal cap and with a constitutively active tyrosine kinase domain.

[0003] Drugs that inhibit the tyrosine kinase activity of BCR-ABL1 through an ATP-competitive mechanism, such as Gleevec® / Glivec® (imatinib), Tasigna® (nilotinib) and Sprycel® (dasatinib), are effective in treating CML, but some patients relapse due to the emergence of drug-resistant clones that mutate the SH1 domain and impair inhibitor binding. Tasigna® and Sprycel® maintain efficacy against many Gleevec-resistant mutant forms of BCR-ABL1, but the Threonine 315 to Isoleucine (T315I) mutation remains insensitive to all three drugs, and as a result, CML patients may develop resistance to the treatment. Thus, inhibiting BCR-ABL1 mutations such as T315I remains an unmet medical need. In addition to CML, the BCR-ABL1 fusion protein is responsible for a proportion of acute lymphoblastic leukemias, and agents that target ABL kinase activity are useful in this indication.

[0004] Drugs that target the myristoyl-binding site (so-called allosteric inhibitors) have potential for treating BCR-ABL1 disorders (Zhang et.al., Targeting BCR-ABL by combining allosteric with ATP-binding-site inhibitors. Nature 2010;463:501-6). To prevent the emergence of drug resistance by the use of ATP inhibitors and / or allosteric inhibitors, combination therapies using both types of inhibitors to treat BCR-ABL1-related diseases or disorders can be developed. In particular, there is a need for small molecules or combinations thereof that inhibit the activity of BCR-ABL1 and BCR-ABL1 mutants by the ATP-binding site, the myristoyl-binding site, or by combining both sites.

[0005] Provided herein are BCR-ABL inhibitors that have activity at a site separate from the currently available ATP site of second and third generation TKIs, which may offer an alternative mechanism of inhibition and, when used in combination, may prevent the development of resistance due to acquisition of point mutations in one of the binding sites, thereby addressing unmet medical needs including treating diseases or disorders mediated by BCR-ABL, including CML, ALL, and AML. Summary of the Invention

[0006] Described herein are methods of treating a subject using a BCR-ABL inhibitor for use in treating a disease or disorder mediated by BCR-ABL, particularly Compound I. Also described herein are methods of treating a disease or disorder mediated by BCR-ABL by administering to a subject in need thereof a therapeutically effective amount of a BCR-ABL inhibitor, particularly Compound I, administered without food.

[ka]

[0008] WO 2013 / 171639 A1 describes compound I as being useful for the treatment of diseases that respond to inhibition of the tyrosine kinase enzyme activity of Abelson protein (ABL1), Abelson-related protein (ABL2) and related chimeric proteins, in particular BCR-ABL1.

[0009] Additionally, specific dosing regimens for the methods or uses of the BCR-ABL inhibitors described herein, particularly Compound I, are provided herein.

[0010] In addition, the present specification describes a pharmaceutical combination comprising a) compound I and b) at least one additional therapeutic agent, optionally in the presence of a pharma- ceutical acceptable carrier, for use in treating disease or disorder mediated by BCR-ABL, and a pharmaceutical composition comprising them.Preferably, one additional therapeutic agent is selected from imatinib, nilotinib, dasatinib, bosutinib, ponatinib and bafetinib, more preferably imatinib.In one embodiment, the pharmaceutical combination is administered with food, preferably with a low-fat meal.

[0011] Further features and advantages of the described methods and uses will become apparent from the detailed description that follows. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Compound I is currently being investigated in patients with CML as single agent, as a TKI combination regimen with established CML therapies imatinib, nilotinib or dasatinib in a Phase 1 first-in-human dose-ranging study (NCT02081378), as single agent in a Phase 3 randomized controlled study (ASCEMBL; NCT03106779), and as add-on therapy to frontline imatinib in a Phase 2 study in patients who have not achieved a deep molecular response (defined as BCR-ABL1 transcript levels ≤0.01% on the International Reporting Scale [IS] for ≥1 year of frontline imatinib (ASC4MORE; NCT03578367)).

[0014] For compound I as a single agent, the recommended phase 3 dose in CML patients has been established as 40 mg twice daily (fasted state; maximum tolerated dose was not reached in CML patients with a maximum dose of 200 mg twice daily). In the phase 3 ASCEMBL study in chronic-phase CML patients (not harboring the BCR-ABL1 T315I mutation) previously treated with at least two prior TKIs, compound I monotherapy (40 mg twice daily) demonstrated a statistically significant and clinically meaningful advantage over the ATP-competitive BCR-ABL1 inhibitor bosutinib (500 mg once daily) in terms of the primary endpoint of primary molecular response (BCR-ABL1 ≤ 0.1% at IS) at 24 weeks (25.5% vs. 13.2%; difference 12.2%; 95% CI, 2.19 to 22.3): P = 0.029) and had a favorable safety profile.

[0015] The combination of asciminib and imatinib was well tolerated and showed promising preliminary efficacy in a first-in-human Phase 1 study in patients with CML who were resistant or intolerant to other TKIs. Preliminary PK analyses in this population evaluating potential drug-drug interactions (DDIs) between asciminib and imatinib found that asciminib 40 mg once daily with food and imatinib 400 mg once daily (as imatinib is better tolerated when taken with food) provided exposures of asciminib equivalent to those achieved with the recommended asciminib monotherapy dose in the fasted state. The first-in-human study used an earlier asciminib tablet formulation, which has been shown to provide a modest reduction in asciminib bioavailability when taken with food compared to the fasted state (30-31% reduced exposure with a low-fat meal and 63-64% reduced exposure with a high-fat meal). For the commercial use of Compound I, a slightly modified tablet formulation (future marketing formulation [FMI]) was developed to ensure scalability to commercial batch sizes. Therefore, further investigations were required to better characterize the DDI between imatinib and Compound I and to confirm the food effect (FE) in the commercially available tablet formulation of Compound I.

[0016] Described herein are methods of treating a disease or disorder mediated by BCR-ABL by administering to a subject in need thereof an effective amount of Compound I, or a pharma- ceutically acceptable salt thereof.

[0017] Thus, in one embodiment, a method is provided for treating a disease or disorder mediated by BCR-ABL, comprising administering an effective amount of Compound I or a pharma- ceutically acceptable salt thereof to a subject in need thereof without food. In a further embodiment, administration of Compound I or a pharma- ceutically acceptable salt thereof with food results in a decreased bioavailability in the subject compared to administration of Compound I or a pharma- ceutically acceptable salt thereof without food. In a further embodiment, administration of Compound I or a pharma- ceutically acceptable salt thereof with food results in a 30% to 60% decrease in AUC compared to administration without food.

[0018] In another aspect, a method for treating a disease or disorder mediated by BCR-ABL is provided, comprising administering to a subject in need thereof a pharmaceutical combination comprising an effective amount of compound I or a pharma- ceutically acceptable salt thereof, and an effective amount of at least one additional therapeutic agent, optionally in the presence of a pharma- ceutically acceptable carrier, for use in treating a disease or disorder mediated by BCR-ABL and pharmaceutical compositions comprising the same.Preferably, one additional therapeutic agent is selected from imatinib, nilotinib, dasatinib, bosutinib, ponatinib and bafetinib, more preferably imatinib.In a further aspect, the pharmaceutical combination is administered with food, preferably a low-fat meal.In a further aspect, administration of the pharmaceutical combination with food results in an approximately 2-fold increase in the systemic exposure (AUCinf and AUClast) of compound I and an approximately 1.6-fold increase in the Cmax of compound I compared to compound I taken with food.

[ka]

[0044] Any chemical formulas shown herein are also intended to represent unlabeled and isotopically labeled forms of the compounds. Isotopically labeled compounds have the structure shown by the formulas shown herein, except that one or more atoms are replaced with an atom having a selected atomic mass or mass number. Isotopes that can be incorporated into the compounds of the present disclosure include, for example, 3 H, 11 C. 13 C. 14 C, and 15 These include isotopes of hydrogen, carbon, nitrogen, and oxygen, such as N. Thus, the methods of the invention can include, for example, 3 H and 14 Radioisotopes such as C, or 2 H and 13 It should be understood that compounds incorporating one or more of the above isotopes, including those in which non-radioactive isotopes such as C are present, may be included or may contain such isotopes. Such isotopically labeled compounds may be useful in drug or substrate tissue distribution assays, or for metabolic studies, including radioactive treatment of patients. 14 C), reaction kinetic studies (e.g. 2 H or 3H), detection or imaging techniques such as positron emission tomography (PET) or single photon emission computed tomography (SPECT). In general, isotopically labeled compounds can be prepared by conventional techniques known to those of skill in the art, for example by substituting an appropriate isotopically labeled reagent for a previously used non-labeled reagent.

[0045] The present invention encompasses embodiments including all pharma- ceutically acceptable salts of the compounds useful according to the invention provided herein. As used herein, "pharma- ceutically acceptable salts" refers to derivatives of the disclosed compounds, where the parent compound is modified by converting an acid or base moiety present to its salt form. Examples of pharma- ceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. Pharmaceutically acceptable salts include conventional non-toxic salts of the parent compound formed, for example, from non-toxic inorganic or organic acids.

Lists of suitable salts can be found in Remington's Pharmaceutical Sciences, 17, each of which is incorporated herein by reference in its entirety. th ed., Mack Publishing Company, Easton, Pa., 1985, p. 1418 and Journal of Pharmaceutical Science, 66, 2 (1977). For example, preferred pharma- ceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines. For example, the salt may be a hydrochloride salt.

[0046] The phrase "pharmacologically acceptable" as used herein refers to those compounds, materials, compositions and / or dosage forms which, within the scope of sound medical judgment, are suitable for use in contact with the tissues of human beings and animals without undue toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit / risk ratio.

[0047] Unless otherwise indicated, as used herein, a "dosage" or amount of a BCR-ABL inhibitor, e.g., Compound I, refers to the amount of the free base or free acid form of the compound. In the case of a salt form of a BCR-ABL inhibitor, the actual amount will be adjusted based on the salt form used.

[0048] An "effective amount" refers to an amount sufficient to produce a beneficial or desired result. For example, a therapeutic amount is an amount that achieves a desired therapeutic effect. This amount may be the same as or different from a prophylactically effective amount, which is the amount necessary to prevent the onset of a disease, condition, disorder or syndrome, or associated symptoms. An effective amount may be administered in one or more administrations, applications, or doses. A "therapeutically effective amount" (i.e., an effective dose) of a therapeutic compound will depend on the therapeutic compound selected. The composition may be administered from once or more times daily to once or more times weekly, including less frequent administrations, for example, as described herein. One of ordinary skill in the art will appreciate that certain factors, including, but not limited to, the severity of the disease, condition, disorder, or syndrome, prior treatments, the overall health and / or age of the subject, and other co-occurring diseases, conditions, disorders, or syndromes, may affect the dosage and timing required to effectively treat a subject. Furthermore, treatment of a subject with a therapeutically effective amount of a therapeutic compound described herein may include a single treatment or a series of treatments.

[0049] As used herein, the term "therapeutically effective amount" of a compound described herein refers to an amount of a compound that elicits a biological or medical response in a subject, such as ameliorating symptoms, alleviating a condition, slowing or postponing the progression of a disease, or preventing a disease, condition, disorder, symptom, or syndrome, etc. In one non-limiting embodiment, the term "therapeutically effective amount" refers to an amount of a compound described herein that, when administered to a subject, is effective to at least partially alleviate, inhibit, prevent, and / or ameliorate a disease or disorder mediated by BCR-ABL (e.g., a leukemia selected from chronic myeloid leukemia (CML), acute lymphoblastic leukemia (ALL), and acute myeloid leukemia (AML)).

[0050] As defined herein, a "combination" refers to either a fixed combination in one unit dosage form (e.g., capsule, tablet, sachet or vial), a free (i.e., non-fixed) combination, or a kit of parts for combined administration in which compound I and one or more additional therapeutic agents can be administered independently simultaneously, or separately within a time interval, particularly within such a time interval that allows the combination partners to exhibit a synergistic effect, e.g., a synergistic effect.

[0051] As used herein, "add-on" or "add-on therapy" refers to a collection of therapeutic agents used in a treatment, where a subject undergoing therapy begins a first therapeutic regimen of one or more therapeutic agents, and then begins a second therapeutic regimen of one or more different therapeutic agents in addition to the first therapeutic regimen, such that all of the therapeutic agents used in the treatment are not started at the same time. For example, a BCR-ABL inhibitor such as Compound I is added to a patient already receiving at least one additional therapeutic agent, such as imatinib, nilotinib, dasatinib, bosutinib, ponatinib, and bafetinib. Compared to imatinib and nilotinib, add-on therapy with asciminib results in higher MR at 48 weeks. 4.5 The BCR-ABL1 / ABL ratio of 0.0032% or less reduced the MR by 4.5 logs. 4.5Add-on asciminib was tested in a phase 2, multicenter, open-label, randomized trial (NCT03578367) comparing add-on asciminib to 1L imatinib with continued imatinib versus switching to nilotinib. Cumulative MR was 4.5 Rates of progression-free survival (MR) by week 48 occurred earlier and at a higher rate with add-on asciminib than with imatinib and nilotinib. 4.5 Rates were 19.0% with add-on asciminib 40 mg once daily, 28.6% with add-on asciminib 60 mg once daily, 0% with imatinib, and 14.3% with nilotinib.

[0052] Terms such as "co-administration" or "administration in combination" as used herein are meant to encompass administration of an additional therapeutic agent to a single subject (e.g., patient) in need thereof, and are intended to include treatment regimens in which Compound I and the additional therapeutic agent are not necessarily administered by the same route of administration and / or at the same time. Each of the components of the combinations described herein may be administered simultaneously or sequentially, and in any order. Co-administration includes simultaneous, sequential, overlapping, intermittent, and / or consecutive administration, and any combination thereof.

[0053] As used herein, the term "pharmaceutical combination" means a pharmaceutical composition resulting from the combination (e.g., mixture) of two or more active ingredients and includes both fixed and free combinations of the active ingredients.

[0054] The term "fixed combination" means that the active ingredients are administered simultaneously to a subject in the form of a single entity or dosage.

[0055] The term "free combination" (non-fixed combination) means that the active ingredients as defined herein are administered to a subject as separate entities, either simultaneously, in parallel, or sequentially, in any order, without being limited to a particular time, such administration providing a therapeutically effective level of the compounds in the patient's body. In particular, as used herein (e.g., in any of the embodiments or claims herein), reference to a combination comprising a) compound I and b) at least one additional therapeutic agent refers to a "non-fixed combination", which may be administered independently at the same time or separately within a time interval.

[0056] "Concurrent administration" means that the active ingredients, as defined herein, are administered on the same day.

Actual methods for preparing such dosage forms will be known or apparent to those skilled in the art and are described, for example, in Remington: The Science and Practice of Pharmacy, 22 nd Edition (Pharmaceutical Press, London, UK. 2012).

[0094] Route of Administration and Composition Components In some embodiments, the chemical entities described herein or pharmaceutical compositions thereof can be administered to a subject in need thereof by any acceptable route of administration. Acceptable routes of administration include, but are not limited to, oral, dermal, intracervical, intrasinus, intratracheal, intestinal, epidural, interstitial, intraperitoneal, intraarterial, intrabronchial, intracapsular, intracerebral, intracapsular, intracoronary, intradermal, intraductal, intraduodenal, intradural, intraepidermal, intraesophageal, intragastric, intragingival, intraileal, intralymphatic, intramedullary, intrameningeal, intramuscular, intraovarian, intraperitoneal, intraprostatic, intrapulmonary, intrasinus, intrathecal, intrasynovial, intratesticular, intraarachnoid, intraductal, intratumoral, intrauterine, intravascular, intravenous, intranasal, nasogastric, oral, parenteral, transdermal, epidural, rectal, respiratory (inhalation), subcutaneous, sublingual, submucosal, topical, transdermal, transmucosal, transtracheal, ureteral, urethral, ​​and vaginal. In certain embodiments, the preferred route of administration is parenteral (e.g., intratumoral).

[0095] The composition can be formulated for parenteral administration, for example, for injection by intravenous, intramuscular, subcutaneous, or intraperitoneal route.Generally, such compositions can be prepared as injections, either as liquid solutions or suspensions, or as solid forms suitable for use in preparing solutions or suspensions by adding liquid prior to injection, or these preparations can be emulsified.The preparation of such formulations will be known to those skilled in the art in light of the present disclosure.

[0096] Suitable pharmaceutical forms for use in injections include sterile aqueous solutions or dispersions, formulations containing sesame oil, peanut oil or aqueous propylene glycol, and sterile powders for extemporaneous preparation of sterile injectable solutions or dispersions.In all cases, the form must be sterile and fluid to the extent that it can be easily injected.It should also be stable under the conditions of manufacture and storage and preserved against the contaminating action of microorganisms such as bacteria and fungi.

[0097] The carrier can also be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, etc.), suitable mixtures thereof, and vegetable oils. Proper fluidity can be maintained, for example, by using coating materials such as lecithin, maintaining the required particle size in the case of dispersion, and by using surfactants. Prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it is preferable to include an isotonic agent, for example, sugar or sodium chloride. Prolonged absorption of the injectable composition can be brought about by using agents that delay absorption, for example, aluminum monostearate and gelatin, in the composition.

[0098] Sterile injection solution is prepared by adding the active compound in the required amount to a suitable solvent together with various other ingredients listed above, if necessary, and then sterilizing by filtration.Generally, dispersion is prepared by adding various sterilized active ingredients to a sterile vehicle that contains a basic dispersion medium and other desired ingredients from the ingredients listed above.For the case of sterile powder for preparing sterile injection solution, the preferred preparation method is vacuum drying and freeze-drying technique, which obtains powder of active ingredient and any additional desired ingredients from its previously sterile filtered solution.

[0099] Intratumoral injection is described, for example, in Lammers et al., "Effect of Intratumoral Injection on the Biodistribution and the Therapeutic Potential of HPMA Copolymer-Based Drug Delivery Systems" Neoplasia. 2006, 10, 788-795.

[0100] In certain embodiments, the chemical entities described herein or pharmaceutical compositions thereof are suitable for local administration to the digestive or GI tract, for example, rectal administration. Rectal compositions include, but are not limited to, enemas, rectal gels, rectal foams, rectal aerosols, suppositories, jelly suppositories, and enemas (e.g., retention enemas).

[0102] In certain embodiments, suppositories can be prepared by mixing the chemical entities described herein with suitable non-irritating excipients or carriers, such as cocoa butter, polyethylene glycol or a suppository wax, which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum to release the active compound. In other embodiments, the composition for rectal administration is in the form of an enema.

[0103] In other embodiments, the compounds described herein or pharmaceutical compositions thereof are suitable for localized delivery to the digestive or GI tract by oral administration (eg, in solid or liquid dosage form).

[0104] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the chemical entity is mixed with one or more pharma- ceutically acceptable excipients, such as sodium citrate or dicalcium phosphate, and / or a) fillers or extenders, such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders, such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants, such as glycerol, d) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents, such as paraffin, f) absorption accelerators, such as quaternary ammonium compounds, g) wetting agents, such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents, such as kaolin and bentonite clay, and i) lubricants, such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets, and pills, the dosage forms may also contain buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar or high molecular weight polyethylene glycols, and the like.

[0105] In one embodiment, the composition takes the form of a unit dosage form such as a pill or tablet, and thus the composition may contain a diluent such as lactose, sucrose, dibasic dicalcium phosphate, a lubricant such as magnesium stearate, and a binder such as starch, acacia gum, polyvinylpyrrolidine, gelatin, cellulose, cellulose derivatives, along with the chemical entity provided herein. In another solid dosage form, a powder, marume, solution or suspension (e.g., in propylene carbonate, vegetable oil, PEG, poloxamer 124, or triglycerides) is encapsulated in a capsule (gelatin or cellulose-based capsule). Unit dosage forms in which one or more chemical entities provided herein or additional active agents are physically separated are also contemplated, such as capsules (or tablets in capsules) containing granules of each agent, bilayer tablets, bicompartment gelcaps, and the like. Enteric coated or delayed release oral dosage forms are also contemplated.

[0106] Other physiologically acceptable compounds include wetting agents, emulsifying agents, dispersing agents, or preservatives that are particularly useful for preventing the growth or action of microorganisms. Various preservatives are well known and include, for example, phenol and ascorbic acid.

[0107] In certain embodiments, the excipients are sterile and generally free of undesirable matter. These compositions can be sterilized by conventional, well-known sterilization techniques. Sterility is not required for excipients of various oral dosage forms, such as tablets and capsules. USP / NF standards are usually sufficient.

[0108] In certain embodiments, the solid oral dosage form may further comprise one or more components that chemically and / or structurally pretreat the composition so that the chemical is delivered to the stomach or lower GI (e.g., the ascending colon and / or the transverse colon and / or the distal colon and / or the small intestine). Exemplary formulation techniques are described, for example, in Filipski, KJ, et al., Current Topics in Medicinal Chemistry, 2013, 13, 776-802, which is incorporated herein by reference in its entirety.

[0109] Examples include upper GI targeting approaches such as the Accordion Pill (Intec Pharma), floating capsules, and materials that can adhere to the mucosal wall.

[0110] Other examples include lower GI targeting approaches. Several enteric / pH-responsive coatings and excipients are available to target different regions of the intestinal tract. These materials are usually polymers designed to dissolve or erode at a specific pH range that is selected based on the GI region of desired drug release. These materials also function to protect acid-labile drugs from gastric juices or limit exposure if the active ingredient may irritate the upper GI (e.g., hydroxypropyl methylcellulose phthalate series, Coateric (polyvinyl acetate phthalate), cellulose acetate phthalate, hydroxypropyl methylcellulose acetate succinate, Eudragit series (methacrylic acid-methyl methacrylate copolymer) and Marcoat). Other approaches include dosage forms that respond to the local microflora in the GI tract, enteric pressure disintegrating colon delivery capsules and Pulsincap.

[0111] Ophthalmic compositions may include, but are not limited to, any one or more of the following: viscogens (e.g., carboxymethylcellulose, glycerin, polyvinylpyrrolidone, polyethylene glycol); stabilizers (e.g., Pluronic (triblock copolymers), cyclodextrin); preservatives (e.g., benzalkonium chloride, ETDA, SofZia (boric acid, propylene glycol, sorbitol, and zinc chloride; Alcon Laboratories, Inc.), Purite (a stabilized oxychloro complex; Allergan, Inc.)).

[0112] Topical compositions can include ointments and creams. Ointments are generally semi-solid formulations based on petrolatum or other petroleum derivatives. Creams containing selected active agents are generally viscous liquids or semi-solid emulsions, often oil-in-water or water-in-oil. Cream bases are generally water-washable and contain an oil phase, an emulsified phase, and an aqueous phase. The oil phase, sometimes called the "internal" phase, is generally composed of petrolatum and a fatty alcohol (e.g., cetyl or stearyl alcohol), and the aqueous phase usually, although not necessarily, exceeds the oil phase in volume and generally contains a humectant. Emulsifiers in cream formulations are generally nonionic, anionic, cationic, or amphoteric surfactants. As with other carriers or vehicles, ointment bases must be inert, stable, non-irritating, and non-sensitizing.

[0113] In any of the foregoing embodiments, the pharmaceutical compositions described herein may include one or more of the following: lipids, interbilayer crosslinked multilamellar vesicles, biodegradable poly(D,L-lactic-co-glycolic acid) [PLGA]-based or polyanhydride-based nanoparticles or microparticles, and nanoporous particle-supported lipid bilayers.

[0114] Dosage regimen and mode of administration The dosing regimen is adjusted to provide the optimal response (e.g., therapeutic response) desired. Depending on the compound used, the disease, condition, disorder, or syndrome targeted, and their associated stages, the dosing regimen, i.e., the dose and / or frequency of administration, of a pharmaceutical composition comprising compound I may vary. Depending on the compound used, the disease, condition, disorder, or syndrome targeted, and their associated stages, the dosing regimen, i.e., the dose and / or frequency of administration, of a pharmaceutical combination comprising a) compound I and b) at least one additional therapeutic agent may vary.

[0115] When Compound I is administered in a method for treating a disease or disorder mediated by BCR-ABL, the dosage ranges from about 0.0001 to about 100 mg / kg, more usually from about 0.01 to about 30 mg / kg of the subject's body weight. In certain embodiments, Compound I is administered in a daily dose of about 20 mg to about 400 mg, about 40 mg to about 300 mg, about 80 mg to about 240 mg, about 40 mg to about 80 mg, or about 80 mg. In certain embodiments, Compound I is administered in a daily dose of about 20 mg, about 40 mg, about 80 mg, or about 100 mg. In certain embodiments, Compound I is administered once a day. In other embodiments, Compound I is administered two, three, or four times a day. In a preferred embodiment, Compound I is administered in a total daily dose of about 80 mg, administered in one or two divided doses. In some embodiments, Compound I is administered at a daily dose of 80 mg in two divided doses. In another embodiment, Compound I is administered at a daily dose of 40 mg once daily.

[0116] kit Also included herein are kits for use in methods for treating or preventing cytokine release syndrome or cytokine storm syndrome, which may include Compound I in liquid or lyophilized form, or a pharmaceutical composition containing Compound I. In addition, such kits may include a means for administering Compound I (e.g., syringes and vials, pre-filled syringes, pre-filled pens) and instructions for use. These kits may include, for example, additional therapeutic agents (described elsewhere herein) for delivery in combination with Compound I.

[0117] The phrase "means for administering" is used to refer to any available implementation for systemically administering a drug to a patient, including, but not limited to, droppers, prefilled syringes, vials and syringes, injection pens, autoinjectors, intravenous drips and bags, pumps, etc. Such articles may allow a patient to self-administer a medication (i.e., administer the medication to themselves), a caregiver to administer the medication to a patient, or a physician or other medical professional to administer the medication.

[0118] Each component of the kit is usually enclosed within an individual container, with all the various containers being in a single package along with instructions for use.

[0119] It will be understood that each embodiment may be combined with one or more other embodiments to the extent that such combination is not inconsistent with the description of the embodiment. Further, the embodiments provided above will be understood to include all embodiments, and will be understood to include such embodiments as a result of any combination of the embodiments.

[0120] Other features, objects, and advantages of the described methods and uses will be apparent from the description and drawings, and from the claims. EXAMPLES

[0121] The following examples illustrate the methods and uses described herein. They are not, however, intended to limit the scope of the described methods and uses in any way. Other variations of the embodiments will be readily apparent to those skilled in the art and are encompassed by the appended claims.

[0122] Example 1: Flux analysis To provide further information regarding the food effect (FE) of asciminib (ABL001), experimental in vitro studies were performed to measure the effect of bile components on the dissolution of a 40 mg dose of asciminib and its permeation through an artificial lipid membrane.

[0123] method The donor compartment of a United States Pharmacopeia Method II (USP II) dissolution apparatus (Distek corporation; New Jersey, United States) was filled with 900 mL of maleic acid buffer containing low concentrations of bile salts (to mimic fasting conditions; fasted simulated intestinal fluid [FaSSIF]; 3 mM taurocholate / taurodeoxycholate, 0.2 mM phospholipids / lysophospholipids, pH 5.8), high concentrations of bile salts (to mimic sated intestinal conditions; fed simulated intestinal fluid [FeSSIF]; 10 mM taurocholate / taurodeoxycholate, 2 mM phospholipids / lysophospholipids, 0.8 / 5.0 mM oleate / glycerol monooleate, pH 6.0), or no bile salts (control; pH 6.5). FaSSIF and FeSSIF were prepared according to the manufacturer's instructions (Biorelevant, available at Biorelevant.com (accessed March 2021)). In each of the three configurations, two film-coated tablets of asciminib, 20 mg (to achieve a total dose of 40 mg) were added to the buffer and maintained at 37 °C with constant stirring (100 rpm). A receiver compartment, sealed by a 0.45 μm polyvinylidene fluoride membrane and an artificial lipid membrane and containing 12 mL of a proprietary acceptor buffer (pION, Inc; Massachusetts, USA), which facilitates solubilizing poorly soluble molecules to high concentrations, was then inserted into the donor compartment. The dissolution and flux rates of asciminib were determined by measuring the asciminib concentrations in the donor and receiver compartments using a fiber optic probe. Two replicates were performed per condition.

[0124] Observations and Results Fat uptake has been shown to be positively correlated with the levels of excreted bile acids, therefore this difference in bile composition was intended to reflect fed and fasted conditions (Trefflich et al. Associations between Dietary Patterns and Bile Acids-Results from a Cross-Sectional Study in Vegans and Omnivores. Nutrients 2019;12(1)). Asciminib dissolution rate was fastest in a buffer containing a composition of bile salts, acids, and lipids that mimicked the fed state (FeSSIF), slower in a buffer that mimicked the fasted state (FaSSIF), and slowest in a control buffer that did not contain bile components (Figure 1A). Conversely, the flux rate of asciminib, or permeation through the artificial lipid membrane, was lowest in the fed-state buffer (FeSSIF; 0.44 μg / min; 94.2% lysis), higher in the fasted-state buffer (FaSSIF; 1.45 μg / min; 93.1% lysis), and highest in the control buffer (2.66 μg / min; 82.3% lysis) (Figure 1B).

[0125] Example 2: A Phase I, Single-Center, Two-Arm, Open-Label Study Evaluating the Effect of Imatinib and Food on the Pharmacokinetics of ABL001 (Aciminib) in Healthy Volunteers The open-label, single-center, phase I study enrolled healthy volunteers in two separate groups: a drug-drug interaction (DDI) study group and a food effect (FE) study group. The two study groups were enrolled independently of each other. Figure 2 is a schematic overview of the treatment protocol.

[0126] The primary goals of this study are to: DDI Study Group To evaluate the effect of repeated once-daily dosing of imatinib 400 mg at steady state on the pharmacokinetics of a single dose of asciminib in healthy subjects under low-fat dietary conditions. FE Test Group To evaluate the FE in the oral bioavailability of a single dose of asciminib in healthy subjects under varying food conditions.

[0127] The primary objectives of the evaluation (EP) are: Primary pharmacokinetic parameters: Cmax, AUCinf, and AUClast of asciminib Secondary pharmacokinetic parameters: Tmax, Tlast, AUC0-96h, lambda_z, T1 / 2, CL / F, Vz / F of v.

[0128] Secondary objectives of this study are to: DDI Study Group To evaluate the safety and tolerability of asciminib administered concomitantly with 400 mg imatinib under low-fat meal conditions in healthy subjects. To evaluate the steady-state pharmacokinetics of imatinib 400 mg once daily when administered in combination with a single dose of asciminib under low-fat meal conditions in healthy subjects. FE Test Group To evaluate the safety and tolerability of a single oral dose of asciminib administered to healthy subjects under varying food conditions.

[0129] Secondary objectives (EPs) were: Safety parameters such as the occurrence of adverse events and serious adverse events, changes in haematology and blood chemistry values, vital signs and electrocardiograms. Secondary pharmacokinetic parameters: Tmax, Tlast, AUC0-96h, lambda_z, T1 / 2, CL / F, Vz / F of imatinib in the DDI study group.

[0130] [Table 1]

[0131] Study design This study was a phase I, single-center, open-label, two-arm design. Each subject underwent a screening period (days -22 to -2), a pretreatment period (baseline, day -1), a treatment period, an end-of-treatment visit, and a 30-day safety follow-up (phone call).

[0132] Test group 1 (DDI test group) The DDI study arm was a single-sequence, non-randomized arm evaluating the effect of repeated doses of imatinib 400 mg administered with a low-fat meal on the pharmacokinetics (PK) of asciminib. This arm consisted of a screening period of up to 21 days, a baseline period (day -1), and a 13-day treatment period (days 1 to 13), with an additional safety period of 30 days after the last dose.

[0133] The first three subjects enrolled in the DDI group were planned to undergo an additional 3-day safety phase following their end-of-treatment visit. If no safety findings were observed in the first three subjects, the study was planned to continue enrolling the remaining 20 subjects. If one of the three subjects had a meeting-criterion safety finding, three more subjects were planned to be enrolled and observed for a minimum period of 17 days before continuing with further enrollment in the study.

[0134] The treatment sequence for each subject in study group 1 is shown in Table 1. Day 1: After at least 10 hours of fasting, subjects were offered an FDA low-fat meal. A single dose of asciminib 40 mg was administered 30 minutes ± 5 minutes after the start of the meal. Days 5-8: Imatinib 400 mg was administered once daily with food and a glass of water. On day 5, blood samples for asciminib were taken before administration of imatinib. Day 9: After at least 10 hours of fasting, subjects were offered an FDA low-fat meal. A single dose of imatinib 400 mg and asciminib 40 mg was administered 30 minutes ± 5 minutes after the start of the meal. Days 10-12: Imatinib 400 mg was administered once daily with food and a glass of water.

[0135] [Table 2]

[0136] Test group 2 (FE test group) The FE study arm was a crossover randomized arm evaluating the effect of different food conditions on the PK of asciminib. The study consisted of a screening period of up to 21 days, three baseline periods (one baseline period before each treatment period), and three treatment periods (each separated by a 7-day washout), with an additional safety period of 30 days after the last dose. Each subject received three treatment periods during which asciminib was administered under fasting conditions, with a low-fat meal, or with a high-fat meal.

[0137] Subjects were randomized to one of six treatment sequences, with approximately four subjects in each treatment sequence. Each subject received three treatment periods, separated by seven days of rest, beginning on the dosing date of the previous treatment period and ending on (including) the baseline date of the next period. End-of-treatment (EOT) assessments were performed 3 days after administration of the last dose of study treatment. Safety follow-up by telephone was scheduled 30 days after the last dose.

[0138] The treatment sequence for each subject in study group 2 is shown in Table 2.

[0139] All subjects were to receive a single oral dose of asciminib tablets 40 mg under various food conditions on days 1, 8, and 15. All subjects received three doses of asciminib on days 1, 8, and 15.

[0140] [Table 3]

[0141] Dietary Requirements and Treatment Dosage During the screening process and throughout the study period, subjects were advised to avoid strenuous exercise and saunas, and were reminded to limit their intake of alcohol, poppy seed-containing foods, caffeinated foods and beverages, and fruits (e.g., grapefruit, starfruit, cranberries, pamelo, pomegranate, and Serbian oranges), which are known to inhibit CYP3A4.

[0142] Test group 1 (DDI test group) In the morning after an overnight fast of at least 10 hours, asciminib was administered with 240 mL of water, 30 ± 5 minutes after the start of an FDA low-fat breakfast. Imatinib was administered in the morning with food (standard) and approximately 200 mL of water. On day 9, imatinib and asciminib were administered 30 ± 5 minutes after the start of a low-fat breakfast with 240 mL of water, with imatinib taken first and asciminib taken immediately after. No food was permitted for at least 4 hours after administration of asciminib and asciminib + imatinib, and for at least 1 hour on days when imatinib was received alone.

[0143] Test group 2 (FE test group) In the morning after an overnight fast of at least 10 hours, asciminib was administered under fasting conditions (i.e., without breakfast) with 240 mL of water, 30 ± 5 minutes after the start of a low-fat breakfast or 30 ± 5 minutes after the start of a high-fat breakfast. In all three food conditions, participants were asked to fast for four hours after receiving asciminib.

[0144] The composition of the high-fat and low-fat diets was based on the guidance of the US Food and Drug Administration (FDA), which states that a high-fat diet is 800-1000 calories, approximately 50% fat, approximately 35% carbohydrate, and approximately 15% protein, while a low-fat diet is 400 calories or less and less than 20% fat (FDA Guidance on Food Effect Studies, Dec 2002).

[0145] Fluid intake was withheld from 1 hour before dosing until 1 hour after dosing, except for fluids consumed with breakfast before dosing and water consumed to administer study medication. Water was otherwise available on request.

[0146] Participants were required to consume the entirety of the offered food within 30 min, and any events of incomplete food intake were recorded. Asciminib and imatinib were administered as film-coated tablets.

[0147] Group Approximately 47 healthy adult male and female subjects who meet the inclusion and exclusion criteria are planned to be enrolled in the study.

[0148] Main inclusion criteria Body mass index (BMI) between 18.0 and 29.9 kg / m 2 Adult male and / or female (infertile or postmenopausal) subjects aged 18-55 years in good health, as determined by medical history, physical examination, vital signs and electrocardiogram (ECG), and laboratory tests, were enrolled in the study.

[0149] Main Exclusion Criteria History of cardiac or cardiac repolarization abnormalities, immunodeficiency disease, any surgical or medical condition that may interfere with the absorption, distribution, metabolism, or excretion of the study therapeutic agent, history of malignancy of any organ system (other than localized basal cell carcinoma of the skin or cervical carcinoma in situ), and smoking.

[0150] Pharmacokinetic sampling and evaluation In the DDI group, asciminib blood concentrations were assessed on days 1-5 and 9-13, with samples taken pre-dose and at 0.5, 1, 2, 3, 4, 6, 8, 10, and 12 hours post-dose (days 1 and 9), 24 and 36 hours post-dose (days 2 and 10), and 48, 72, and 96 hours post-dose (days 3-5 and 11-13). The PK of imatinib was assessed over days 9-10 and 12-13 with samples taken pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10 and 12 hours post-dose (days 9 and 12) and 24 hours post-dose (days 10 and 13). In the FE group, the PK of asciminib was evaluated across days 1-4 of each of the three treatment periods, with samples collected pre-dose and at 0.5, 1, 2, 3, 4, 6, 8, 10, and 12 hours post-dose (day 1), 24 and 36 hours post-dose (day 2), and 48, 72, and 96 hours post-dose (days 3-4). Plasma concentrations of asciminib and imatinib were measured using a validated liquid chromatography tandem mass spectrometry assay (LC-MS / MS) with a dynamic range of 1.00-5000 ng / mL for asciminib and 20.0-10,000 ng / mL for imatinib. The method was validated for specificity, sensitivity, matrix effect, recovery, linearity, accuracy and precision, completeness of dilution, batch size, and stability. For the analysis of asciminib, the accuracy and precision of the LLOQ (1.00ng / mL) were within ±5.0% bias and ≦8.0%CV, respectively. Based on the intraday and interday evaluations, the accuracy (% bias) of the other internal standard solution samples was in the range of -2.0~5.3%, and the precision was 2.8~6.2%CV. For the analysis of imatinib, the accuracy and precision of the LLOQ (20.0ng / mL) were within ±1.5% bias and ≦8.8%CV, respectively. Based on the intraday and interday evaluations, the accuracy (% bias) of the other internal standard solution samples was in the range of -5.0%~1.8%, and the precision was 3.4%~7.4%CV.

[0151] statistical analysis Assuming an intrasubject variability of 30% for the key PK parameters of asciminib (based on previously reported data17), a sample size of 18 participants per group was estimated to provide sufficient precision of the 90% CI for the difference between the test and reference parameters on the log scale, with margin of error for the observed mean difference of 0.170 in the DDI group and 0.166 in the FE group (based on a paired t-test with a two-sided alpha level of 0.10). Taking into account a potential discontinuation rate of 20%, it was decided to enroll 23 participants in the DDI group and 24 participants in the FE group. PK analyses were based on all participants with at least one evaluable PK profile. In the DDI group, participants were considered evaluable for their PK profile if they received all planned doses of imatinib on days 5-9 (day 9 profile), all planned doses of imatinib on days 5-9 and at least 2 planned doses of imatinib on days 10-12 (day 12 profile), received the planned doses of asciminib on the corresponding days, met pre-specified fasting requirements, did not vomit within 4 hours after administration of asciminib and / or imatinib, and provided at least one primary PK parameter of asciminib (asciminib PK profile) or at least one primary PK parameter of imatinib (imatinib PK profile). In the FE group, participants were considered evaluable for the PK profile of asciminib if they received one of the planned treatments, consumed at least 75% of the food for each feeding treatment, met prespecified treatment dosing requirements, provided at least one primary asciminib PK parameter, met prespecified fasting requirements, and did not vomit within 4 hours after asciminib administration. · The safety population for both arms consisted of all participants who received at least one dose of study treatment. PK parameters were calculated from individual plasma concentration-time profiles using noncompartmental methods with Phoenix WinNonlin® (Pharsight, Mountain View, CA) software version 6.4. PK parameters were summarized using geometric mean (Gmean), geometric coefficient of variation (GCV%), median, minimum, and maximum. Baseline characteristics are expressed as frequencies and percentages for categorical data and median, minimum, and maximum for continuous data. Missing values ​​and values ​​below the LLOQ were treated as missing in the calculation of Gmean and GCV%. Formal statistical comparisons were performed for the primary asciminib PK parameters of Cmax, AUCinf, and AUClast. Formal statistical comparisons of asciminib + imatinib (study) versus asciminib alone (reference) were evaluated in the DDI arm. Linear mixed models were fitted to the log-transformed PK parameters, including treatment as a fixed factor and participant as a random factor. Formal statistical comparisons of low-fat meal (study) versus fasted (reference) and high-fat meal (study) versus fasted (reference) were assessed in the FE group. Linear mixed models were fitted to the log-transformed PK parameters, including treatment, period, and sequence as fixed factors and participant nested within sequence as a random factor. For all comparisons, point estimates of the difference between study and reference and corresponding two-sided 90% confidence intervals (CIs) were calculated. The point estimates and CIs were antilog transformed to obtain estimates of the geometric mean (Gmean) ratios and 90% CIs on the original scale. The secondary PK parameters are only descriptive. All analyses were performed using the Statistical Analysis System (SAS) version 9.4.

[0152] safety Monitor by assessing physical examination, vital signs, height and weight, laboratory evaluations, cardiac evaluations, dietary records as well as collecting adverse events (AEs) at each visit. AEs were coded using the Medical Dictionary for Regulatory Affairs (MedDRA) version 20.1 and the Common Terminology Criteria for Adverse Events [CTCAE] version 4.03. All clinical specimen analyses (haematology, blood chemistry analyses) were performed at local laboratories.

[0153] result Participant demographics and baseline characteristics Overall, 47 participants were enrolled in the study, including 23 participants in the DDI group and 24 participants in the FE group. In the DDI group, the first three participants enrolled underwent an additional 3-day safety phase after the end-of-treatment visit (sentinel dosing). No safety findings were observed in these three participants, which led to the enrollment of the remaining 20 participants. Twenty-two participants completed the DDI study, and all 22 participants received all planned doses of asciminib on days 1 and 9, and all eight doses of imatinib on days 5–12. One participant was discontinued on day 5 due to vomiting within 4 hours of imatinib administration (grade 1 vomiting) and was removed from the imatinib PK analysis population per protocol. In the FE group, all 24 enrolled participants (4 participants per 6 sequences) completed the study and all participants received the full planned dose of asciminib. One participant did not receive asciminib within 30 ± 5 minutes after starting a meal during one of the treatment periods and was excluded from the PK analysis. In the DDI group, the median age at baseline was 47.0 years (range, 23-55 years), the median body mass index (BMI) was 25.3 (range, 19.1-29.5), 87.0% (20 / 23) participants were male, 95.7% (22 / 23) were Caucasian, and one participant was African American. In the FE group, the median age (range) was 44.5 years (21-54 years), the median BMI was 24.65 (range 19.7-29.4), 95.8% (23 / 24) of participants were male, and all participants were white. One participant in the DDI group received concomitant paracetamol (500 mg once daily) for headache on days 5 and 6. No concomitant medication was administered in the FE group.

[0154] PK analysis of DDI group The plasma concentration-time profile of asciminib revealed that asciminib administered with imatinib at steady state resulted in higher exposure compared with asciminib administered alone (Figure 3A). With both regimens, rapid absorption was followed by a biphasic decline after Cmax was reached. Descriptive PK parameters showed higher exposure with asciminib when administered in combination with imatinib than with asciminib monotherapy (Table 1). Median Tmax was similar whether asciminib was administered alone (3.00 h; range 1.01–6.00 h) or with imatinib (3.00 h; range 1.94–4.00 h). Gmean of T1 / 2 was similar between asciminib combined with imatinib (15.3 h) and asciminib without imatinib (13.7 h). Gmean of asciminib clearance was 5.19 L / h when asciminib was administered with imatinib, but was higher at 11.1 L / h when asciminib was administered alone. Statistical comparison of primary asciminib PK parameters demonstrated that asciminib + imatinib increased systemic asciminib exposure approximately 2-fold compared with asciminib alone (Gmean ratio [90% CI] comparing asciminib + imatinib vs. asciminib, AUCinf, 2.08 [1.93; 2.24]; AUClast, 2.07 [1.92; 2.23]) and Cmax, 1.6 (Gmean ratio [90% CI], 1.59 [1.45; 1.75]) (Table 3). The intersubject variability (GCV%) of AUCinf and AUClast was similar between asciminib alone and asciminib + imatinib (31.7-31.8% vs. 27.0-28.0), and Cmax was higher with asciminib alone than with asciminib + imatinib (33.4% vs. 16.1%) (Table 4).

[0155] Plasma concentration-time profiles of imatinib demonstrated slightly lower and slightly delayed exposure to imatinib when asciminib was coadministered with imatinib compared with imatinib administered alone. This effect was observed primarily during the absorption phase, with delayed absorption of imatinib in the presence of asciminib (Figure 3B). PK parameters of imatinib comparing asciminib + imatinib to imatinib alone were AUClast Gmean 29,600ng×h / mL (GCV% 27.3%) vs. 33,600ng×h / mL (GCV% 28.6%), AUC0-24h Gmean 30,100ng×h / mL (GCV% 27.4%) vs. 33,600ng×h / mL (GCV% 28.6%), and Cmax Gmean 2020ng / mL (GCV% 26.9%) vs. 2340ng / mL (GCV% 29.5%). The median Tmax of imatinib was similar whether imatinib was administered with asciminib (3.01 [range 1.95-5.00] hours) or alone (3.00 [range 0.993-5.95] hours).

[0156] [Table 4]

[0157] [Table 5]

[0158] PK analysis of the FE group Plasma concentration-time profiles of asciminib under different food conditions showed that administration with food reduced the exposure of asciminib and delayed the Tmax, especially with a high-fat meal, compared with fasting conditions (Figure 4). Similarly, descriptive PK parameters demonstrated lower exposure to asciminib when administered with a high-fat or low-fat meal compared to fasted conditions, with a greater decrease in exposure observed with a high-fat meal compared to a low-fat meal (Table 5). The median Tmax (range) of asciminib was longer when asciminib was administered with a high-fat meal (4.01 [1.00-8.00] hours) or a low-fat meal (3.00 [0.997-5.00] hours) compared with the fasted state (2.01 [1.00-5.00] hours).

[0159] These findings were confirmed by statistical comparison of asciminib PK parameters, which showed that the higher the fat content of the accompanying food, the lower the exposure to asciminib (Table 6). For example, the Gmean ratio of AUCinf was 0.700 (90% CI 0.631–0.776) under low-fat fed conditions, indicating a 30% reduction in exposure compared to fasted conditions. Under high-fat meal conditions, the Gmean ratio for AUCinf was 0.377 (90% CI 0.341-0.417), indicating a 62.3% decrease in exposure compared to the fasted state. A similar pattern was observed for AUClast and Cmax. Inter-subject variability for primary PK parameters was slightly higher when asciminib was administered with a high-fat meal (GCV% AUCinf 43.9%, AUClast 43.8%, Cmax 51.3%) compared to low-fat meal (GCV% AUCinf 29.1%, AUClast 29.0%, Cmax 39.8%) or fasted conditions (GCV% AUCinf 35.5%, AUClast 35.2%, Cmax 39.7%) (Table 5).

[0160] The observed food effects on the PK of asciminib in healthy subjects were also supported by experimental in vitro flux studies in Example 1, which assessed the effect of different bile compositions on how a 40 mg dose of asciminib dissolves and permeates an artificial lipid membrane.

[0161] [Table 6]

[0162] [Table 7]

[0163] safety A single 40 mg dose of asciminib was well tolerated in both study arms. This was also true for the sentinel asciminib + imatinib cohort in the DDI group, so enrollment and treatment were expanded to all DDI cohorts. In the DDI group, at least one AE was reported in 14 participants (60.9%). The most frequently reported AEs (≥5% of participants) were headache (n=5, 21.7%), arthralgia, erythema, fatigue, feeling hot, nasal congestion, nasopharyngitis, and vomiting (n=2 each, 8.7%). In the FE group, 11 participants (45.8%) had at least one AE, with the most frequently reported AEs being oropharyngeal pain and rhinitis (n=2 each, 8.3%). In both study arms, all AEs were CTCAE grade 1 or 2, and there were no serious AEs. There were no clinically significant abnormalities in laboratory assessments, vital signs, or ECGs. In the DDI group, one participant had grade 3 neutrophil counts and grade 2 white blood cell counts. In the FE group, one participant had a grade 3 triacylglycerol lipase elevation on day 2 of the fasting treatment period that improved to normal by day 3. Another participant in the FE group had grade 2 triglyceride elevations on days 2-6 of the low-fat treatment period and on day 9 of the fasting period to EOT, a grade 2 cholesterol elevation on day 14 of the high-fat treatment period to EOT that returned to normal by day 31, and a grade 3 lipase elevation on day 16 of the high-fat treatment period that improved to normal by day 18. There were no other hematological or biochemical abnormalities of grade 3 or higher in either the DDI or FE groups.

[0164] Consideration This Phase 1 study evaluated the effect of steady-state (low-fat meal conditions) or perturbation of food conditions of imatinib on the PK of a single 40 mg dose of asciminib (FMI tablet formulation) in healthy volunteers. Imatinib, and therefore the asciminib + imatinib combination, should be administered with food to minimize gastric discomfort. This DDI study compares asciminib with and without imatinib when taken under the same standard FDA low-fat meal conditions; therefore, any PK differences between the two settings are expected to reflect the DDI between asciminib and imatinib. Asciminib + imatinib (taken with a low-fat meal) resulted in a 2-fold increase in the systemic exposure of asciminib (AUCinf and AUClast) and a 1.6-fold increase in the Cmax of asciminib compared to asciminib alone (taken under the same food conditions). - The Tmax of asciminib was not substantially different between asciminib alone and asciminib plus imatinib. The PK parameters of imatinib observed in this study were comparable to those previously reported in a dose-ranging study of imatinib alone in patients with CML (Peng et.al.,Clinical pharmacokinetics of imatinib.Clin Pharmacokinet 2005;44(9);879-94) and to those observed with imatinib plus asciminib in patients with CML (Cortes et.al..Combination Therapy Using Asciminib Plus Imatinib in Patients With Chronic Myeloid Leukemia:Results From a Phase 1 Study.Presented at the European Hematology Association 24th Annual Congress;2019;Amsterdam,the Netherlands), indicating that asciminib is unlikely to affect the PK of imatinib.

[0165] The observed effect of imatinib on asciminib exposure may be due to the fact that imatinib inhibits multiple pathways involved in the metabolism of asciminib. Asciminib undergoes direct glucuronidation via several UDP-glucuronosyltransferases (UGTs; mainly UGT2B7 and UGT2B17) and oxidation, mainly via CYP3A4, and is also a substrate for breast cancer resistance protein (BCRP), with biliary secretion contributing to its clearance (Tran et al.,Disposition of asciminib,a potent BCR-ABL1 tyrosine kinase inhibitor,in healthy male subjects.Xenobiotica 2020;50(2);150-69). On the other hand, imatinib is an in vitro reversible moderate inhibitor of CYP3A4, 14 a highly potent inhibitor of various UGTs with UGT2B17, 23 and an inhibitor of BCRP and P-glycoprotein (D'Cunha et al., TKI combination therapy; strategy to enhance dasatinib uptake by inhibiting Pgp- and BCRP-mediated efflux. Biopharm Drug Dispos 2016;37(7);397-408).

[0166] Importantly, the maximum tolerated dose of single-agent asciminib in patients with CML was not reached at doses up to 200 mg twice daily, so the 2-fold increased asciminib exposure observed in the asciminib + imatinib trial is not expected to adversely affect the safety profile of the combination regimen (Hughes et al.,Asciminib in Chronic Myeloid Leukemia after ABL Kinase Inhibitor Failure. N Engl J Med 2019;381(24);2315-26). Indeed, the AE data from this study, including AE data from the sentinel cohort, together with available safety data for the combination in CML patients, indicate that asciminib + imatinib was well tolerated, with a safety profile consistent with that of single-agent asciminib9, and there were no new safety signals.

[0167] The results of the FE analysis showed that asciminib exposure was reduced when it was administered with food. This effect was more pronounced with a higher fat content of the food, with asciminib AUCinf and AUClast decreasing by 30% with low fat food and 62-63% with high fat food compared to fasting conditions. A delay in Tmax was also observed when asciminib was administered with food compared to fasting conditions, and as already mentioned for exposure, the shift in Tmax increased with the fat content of the food. Presumably, the observed FE of asciminib is related to its sequestration by bile acids, especially when the concentration of bile acids in the gastrointestinal tract is high, such as after a high fat meal. This notion is supported by the results of flux analysis, which showed that the higher the concentration of bile components in the buffer (i.e., the higher the fat content of the ingested meal 20), the slower the flux rate of asciminib (i.e., the longer the Tmax and the slower the rate of absorption of asciminib in vivo).

[0168] The absolute measures of AUCinf, AUClast, and Cmax of asciminib observed with the asciminib FMI tablet formulation in this study, as well as the magnitude of FE, are consistent with previous FE results with earlier asciminib formulations. With these earlier asciminib tablet formulations, asciminib exposure was reduced by approximately 30% and approximately 65% ​​with low-fat and high-fat meals, respectively, compared to the fasted state, regardless of tablet variant.15 Based on these FE findings, asciminib (FMI tablet formulation) as a single agent will be administered in the fasted state.

[0169] conclusion This study demonstrated that coadministration of asciminib (FMI tablet formulation) with imatinib resulted in a modest (2-fold) increase in asciminib exposure without changing imatinib exposure compared to asciminib alone taken under the same food conditions. Thus, when used in combination with imatinib (with food), asciminib is administered at 40 mg or 60 mg once daily compared to the recommended asciminib monotherapy dose of 40 mg twice daily in the fasted state (Saglio et al., Randomized, Open-Label, Multicenter, Phase 2 Study of Asciminib (ABL001) As an Add-on to Imatinib Versus Continued Imatinib Versus Switch to Nilotinib in Patients with Chronic Myeloid Leukemia in Chronic Phase Who Have Not Achieved a Deep Molecular Response with Frontline Imatinib. ASH;2019;2019.p.(Supplement_1);5910). Food itself, especially high-fat meals, results in a modest (30-60%) decrease in asciminib exposure depending on the fat content, possibly related to sequestration of asciminib by bile acids. Therefore, it is recommended that asciminib as a single agent be administered in the fasted state to avoid suboptimal exposure. The combination of asciminib + imatinib was well tolerated in this study in healthy volunteers, which is consistent with the preliminary clinical experience in CML patients. Overall, the findings indicate that coadministration of imatinib 400 mg once daily with asciminib 40 mg once daily under low-fat meal conditions resulted in a modest increase in asciminib exposure similar to that achieved with the recommended asciminib monotherapy dose (40 mg twice daily) under fasted conditions, with a favorable safety profile.Asciminib, at 40 mg or 60 mg once daily, is currently being further investigated as add-on therapy to imatinib in a phase 2 randomized trial (NCT03578367) in patients with chronic-phase CML who have received first-line imatinib and failed to achieve a deep molecular response.
