The MAPK pathway is an evolutionarily conserved cell signaling pathway that regulates a variety of cellular processes, including cell cycle progression, cell migration, cell survival, differentiation, metabolism, proliferation and transcription. ERK1 / 2 activity is commonly upregulated in cancer as a result of activating mutations within upstream components of the MAPK pathway. ERK1 / 2 inhibitors are useful in therapy, particularly in the treatment of cancer. Summary of the Invention [Problem to be solved by the invention]

[0013] definition The following description illustrates exemplary embodiments of the present technology, however, it should be appreciated that such description is not intended to limit the scope of the disclosure, but is instead provided as a description of exemplary embodiments.
[0014] As used herein, the following words, phrases and symbols are generally intended to have the meanings set forth below, unless the context in which they are used indicates otherwise.
[0015] A dash ("-") that is not between two letters or symbols is used to indicate the point of attachment of a substituent. For example, -C(O)NH2 is attached through a carbon atom. Dashes at the beginning or end of a chemical group are for convenience, and chemical groups may be shown with one, multiple dashes, or none, without loss of normal meaning. A drawn wavy line in a structure indicates the point of attachment of a group. No directionality is given or implied by the order in which chemical groups are written or named unless chemically or structurally necessary.
[0016] As used herein, reference to "about" a value or parameter includes (describes) embodiments directed to the value or parameter itself. In certain embodiments, the term "about" includes ±10% of the indicated amount. In other embodiments, the term "about" includes ±5% of the indicated amount. In certain other embodiments, the term "about" includes ±1% of the indicated amount. Also, the term "about X" includes a description of "X." Additionally, the singular forms "a" and "the" include plural referents unless the context clearly indicates otherwise. Thus, for example, reference to a "compound" includes a plurality of such compounds, and reference to an "assay" includes reference to one or more assays and equivalents thereof known to those of skill in the art.
[0017] "Alkyl" refers to an unbranched or branched saturated hydrocarbon chain. As used herein, alkyl has 1 to 20 carbon atoms (i.e., C1-20 alkyl), 1 to 8 carbon atoms (i.e., C1-8 alkyl), 1 to 6 carbon atoms (i.e., C1-6 alkyl), or 1 to 4 carbon atoms (i.e., C1-4 alkyl). Examples of alkyl groups include methyl, ethyl, propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, pentyl, 2-pentyl, isopentyl, neopentyl, hexyl, 2-hexyl, 3-hexyl, and 3-methylpentyl. When an alkyl residue having a particular number of carbons is indicated in a chemical name or specified by a molecular formula, all positional isomers having that number of carbons can be included, thus, for example, "butyl" includes n-butyl (i.e., -(CH2)3CH3), sec-butyl (i.e., -CH(CH3)CH2CH3), isobutyl (i.e., -CH2CH(CH3)2), and tert-butyl (i.e., -C(CH3)3), and "propyl" includes n-propyl (i.e., -(CH2)2CH3) and isopropyl (i.e., -CH(CH3)2).
[0018] "Alkenyl" refers to an alkyl group containing at least one carbon-carbon double bond and having from 2 to 20 carbon atoms (i.e., C2-20 alkenyl), from 2 to 8 carbon atoms (i.e., C2-8 alkenyl), from 2 to 6 carbon atoms (i.e., C2-6 alkenyl), or from 2 to 4 carbon atoms (i.e., C2-4 alkenyl). Examples of alkenyl groups include ethenyl, propenyl, and butadienyl (including 1,2-butadienyl and 1,3-butadienyl).
[0019] "Aryl" refers to an aromatic carbocyclic group having a single ring (e.g., monocyclic) or multiple rings, including fused systems (e.g., bicyclic or tricyclic). As used herein, an aryl has 6 to 20 ring carbon atoms (i.e., C6-20 aryl), 6 to 12 carbon ring atoms (i.e., C6-12 aryl), or 6 to 10 carbon ring atoms (i.e., C6-10 aryl). Examples of aryl groups include phenyl, naphthyl, fluorenyl, and anthryl. However, aryl does not encompass or overlap in any way with heteroaryl, as defined below. When one or more aryl groups are fused to a heteroaryl, the resulting ring system is a heteroaryl. When one or more aryl groups are fused to a heterocyclyl, the resulting ring system is a heterocyclyl.
[0020] "Cycloalkyl" refers to a saturated or partially unsaturated cyclic alkyl group having a single ring or multiple rings, including fused, bridged, and spiro ring systems. The term "cycloalkyl" includes cycloalkenyl groups (i.e., cyclic groups having at least one double bond). As used herein, cycloalkyl has 3 to 20 ring carbon atoms (i.e., C3-20 cycloalkyl), 3 to 12 ring carbon atoms (i.e., C3-12 cycloalkyl), 3 to 10 ring carbon atoms (i.e., C3-10 cycloalkyl), 3 to 8 ring carbon atoms (i.e., C3-8 cycloalkyl), or 3 to 6 ring carbon atoms (i.e., C3-6 cycloalkyl). Examples of cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl, and cyclohexyl.
[0021] As used herein, "hydroxypropyl methylcellulose acetate succinate" may be referred to interchangeably as HPMCAS or hypromellose acetate succinate (e.g., Aquasolve™, Shin-Etsu AQOAT™, or other commercially available equivalents). HPMCAS is commercially available in a variety of grades (e.g., L, M, or H) having various molecular weights (e.g., 10,000-500,000 da) and differing degrees of substitution of acetyl and succinoyl groups as well as particle size (e.g., F or G). For example, the L grade of Aquasolve™ is commercially available and comprises an acetyl content of 5-9%, a succinoyl content of 14-18%, a methoxyl content of 20-24%, and a hydroxypropoxy content of 5-9%. For example, Aquasolve™ M grade is commercially available and comprises an acetyl content of 7-11%, a succinoyl content of 10-14%, a methoxyl content of 21-25%, and a hydroxypropoxy content of 5-9%. For example, Aquasolve™ S grade is commercially available and comprises an acetyl content of 10-14%, a succinoyl content of 4-8%, a methoxyl content of 22-26%, and a hydroxypropoxy content of 6-10%. Each grade is available in fine (F) and granular (G) particle sizes. In some cases, the fine (F) type has an average particle size of 10 microns or less, and the granular (G) type has an average particle size of 20 microns or less.
[0022] The term "optionally" or "optionally" means that the next described event or circumstance may or may not occur, and the description includes cases where said event or circumstance occurs and cases where said event or circumstance does not occur. Also, the term "optionally substituted" refers to any one or more hydrogen atoms on a specified atom or group may or may not be replaced with a non-hydrogen moiety.
[0023] Some of the compounds may exist as tautomers. Tautomers are in equilibrium with each other. For example, an amide-containing compound may exist in equilibrium with an imidic acid tautomer. Regardless of which tautomer is shown, and regardless of the nature of the equilibrium between the tautomers, one skilled in the art will understand that the compound comprises both amide and imidic acid tautomers. Thus, amide-containing compounds are understood to include their imidic acid tautomers. Similarly, imidic acid-containing compounds are understood to include their amide tautomers.
[0024] Any formula or structure shown herein is also intended to represent unlabeled form of the compound as well as isotopically labeled form.Isotopically labeled compounds have the structure shown by the formula given herein, except that one or more atoms are replaced by an atom with selected atomic mass or mass number.Examples of isotopes that can be incorporated into the compounds of the present disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine and chlorine, such as, but not limited to, 2H (deuterium, D), 3H (tritium), 11C, 13C, 14C, 15N, 18F, 31P, 32P, 35S, 36Cl and 125I.Various isotopically labeled compounds of the present disclosure, such as compounds incorporating radioisotopes such as 3H and 14C. Such isotopically labeled compounds may be useful for detection or imaging techniques such as positron emission tomography (PET) or single photon emission computed tomography (SPECT) including metabolism studies, reaction kinetics studies, drug or substrate tissue distribution assays, or for radiotherapy of patients.
[0025] The present disclosure also includes "deuterated analogs" of compounds of formula I in which one to n hydrogens attached to a carbon atom are replaced with deuterium, where n is the number of hydrogens in the molecule. Such compounds exhibit increased resistance to metabolism and are therefore useful for extending the half-life of compounds of formula I when administered to mammals, particularly humans. See, e.g., Foster, "Deuterium Isotope Effects in Studies of Drug Metabolism," Trends Pharmacol. Sci. 5(12):524-527 (1984). Such compounds are synthesized by means well known in the art, e.g., using starting materials in which one or more hydrogens have been replaced with deuterium.
[0026] The deuterium-labeled or substituted therapeutic compounds of the present disclosure may have improved DMPK (drug metabolism and pharmacokinetic) properties related to distribution, metabolism and excretion (ADME). Substitution with heavy isotopes such as deuterium may provide certain therapeutic advantages resulting from higher metabolic stability, such as extended in vivo half-life, reduced dose requirements, and / or improved therapeutic index. 18F-labeled compounds may be useful for PET or SPECT studies. The isotopically-labeled compounds of the present disclosure and their prodrugs can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations below, replacing non-isotopically labeled reagents with readily available isotopically labeled reagents. It is understood that deuterium in this context is considered as a substituent in the compound of formula I.
[0027] The concentration of such heavy isotopes, specifically deuterium, can be defined by the isotopic enrichment factor. In the compounds of the present disclosure, an atom that is not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Unless otherwise noted, when a position is specifically designated as "H" or "hydrogen", that position is understood to have hydrogen at its natural abundance isotopic composition. Thus, in the compounds of the present disclosure, an atom specifically designated as deuterium (D) is meant to represent deuterium.
[0028] In many cases, the compounds of the present disclosure may form acid and / or base salts due to the presence of amino and / or carboxyl groups or groups similar thereto. "Salts" may be derived from inorganic acids, inorganic bases, organic acids, or organic bases. Salts derived from inorganic acids include salts from hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like. Salts derived from organic acids include those from acetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, malic acid, malonic acid, mandelic acid, succinic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluene-sulfonic acid, salicylic acid, tetrahydrofuran carboxylic acid, and the like. Salts derived from inorganic bases include, by way of example only, sodium, potassium, lithium, ammonium, calcium, and magnesium salts. Salts derived from organic bases include, but are not limited to, salts of primary, secondary, and tertiary amines.
[0029] Also provided are compositions comprising pharma- ceutically acceptable salts, hydrates, solvates, and tautomeric forms of Compound I, as described herein. "Pharmaceutically acceptable" or "physiologically acceptable" refers to compounds, salts, compositions, dosage forms, and other materials useful in preparing pharmaceutical compositions suitable for veterinary or human pharmaceutical use.
[0030] The term "pharmaceutical acceptable salt" of a given compound refers to a salt that retains the biological effectiveness and properties of the given compound and is not biologically or otherwise undesirable. "Pharmaceutical acceptable salt" or "physiologically acceptable salt" includes, for example, salts with inorganic acids and salts with organic acids. Furthermore, when a compound described herein is obtained as an acid addition salt, the free base can be obtained by basifying a solution of the acid salt. Conversely, when the product is a free base, an addition salt, particularly a pharmaceutical acceptable addition salt, can be produced by dissolving the free base in a suitable organic solvent and treating the solution with an acid according to conventional procedures for preparing acid addition salts from basic compounds. Those skilled in the art will recognize various synthetic methodologies that can be used to prepare non-toxic pharmaceutical acceptable addition salts. Pharmaceutically acceptable acid addition salts can be prepared from inorganic and organic acids. Salts derived from inorganic acids include those from hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like. Salts from organic acids include those from acetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, malic acid, malonic acid, succinic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluene-sulfonic acid, salicylic acid, and the like. Similarly, pharma-ceutically acceptable base addition salts can be prepared from inorganic and organic bases. Salts derived from inorganic bases include, by way of example only, sodium, potassium, lithium, ammonium, calcium, and magnesium salts.Salts derived from organic bases include, but are not limited to, primary, secondary, and tertiary amines, such as alkylamines (i.e., NH2(alkyl)), dialkylamines (i.e., HN(alkyl)2), trialkylamines (i.e., N(alkyl)3), substituted alkylamines (i.e., NH2(substituted alkyl)), di(substituted alkyl)amines (i.e., HN(substituted alkyl)2), tri(substituted alkyl)amines (i.e., N(substituted alkyl)3), alkenylamines (i.e., NH2(alkenyl)), dialkenylamines (i.e., HN(alkenyl)2), trialkenylamines (i.e., N(alkenyl)3), substituted alkenylamines (i.e., NH2(substituted alkenyl)), di(substituted alkenyl)amines (i.e., HN(alkenyl)2), tri(substituted alkenyl)amines (i.e., N(substituted alkyl)3), Specific examples of suitable amines include, by way of example only, isopropylamine, trimethylamine, diethylamine, tri(iso-propyl)amine, tri(n-propyl)amine, ethanolamine, 2-dimethylaminoethanol, piperazine, piperidine, morpholine, N-ethylpiperidine, and the like.

EXAMPLES
[0065] The following examples are included to illustrate certain embodiments of the present disclosure. Those skilled in the art should understand that the techniques disclosed in the following examples represent techniques that work well in the implementation of the present disclosure and therefore can be considered to constitute certain modes for its implementation.

Where available, reagents can be purchased commercially, for example from Sigma Aldrich or other chemical suppliers.
[0066] Example 1-1: Preparation of a solid dispersion of Compound I:HPMCAS 1:3 The amorphous solid dispersion comprises Compound I:HPMCAS (Shin-Etsu Chemical, M grade, G particle size) in a ratio of 1:3. The solid dispersion was prepared by spray drying a solution of 2 grams of Compound I free base hydrate crystalline form B and 6 grams of HPMCAS from acetone at a solid loading of 10% w / w, or optionally at a loading of about 4% w / w to about 10% w / w. Compound I free base monohydrate crystalline form B was prepared as described in WO2018 / 193410. The solid dispersion was prepared using a spray drying process. The spray drying process included three steps: preparation of the feed solution, spray drying, and secondary drying. To prepare the feed solution, 90% of the total acetone volume was added to the reactor, and then Compound I was added to the reactor. The mixture was stirred at room temperature until the solids were dissolved. HPMCAS (Shin-Etsu Chemical, M grade, G particle size) was added, and the mixture was stirred at room temperature until most of the solids were dissolved. The remaining amount of acetone was added to the reactor and stirring was continued for an additional period of time (>30 min) until the solids were dissolved. For spray drying, the spray dryer (Bend BLD-35) was stabilized with nitrogen gas, then the solution was introduced and the wet spray was collected in a bag, then the collected wet spray dried was secondary dried in a vacuum tray until the residual solvent was 1500 ppm or less. The spray dried material was an amorphous white to off-white solid with a yield of 86.8%.
[0067] Example 1-2: Preparation of a 1:1 solid dispersion of Compound I:HPMCAS The amorphous solid dispersion comprises Compound I:HPMCAS (Shin-Etsu Chemical, M grade, G particle size) in a ratio of 1:1. The solid dispersion was prepared by spray drying 4 grams of Compound I free base hydrate crystal form B and 4 grams of HPMCAS using the same procedure as in Example 1-1.
[0068] Examples 1-3: Preparation of Compound I:HPMC 1:3 solid dispersion The amorphous solid dispersion comprises Compound I:HPMC (JRS PHARMA, Grade E3) in a ratio of 1:3. The solid dispersion was prepared by spray drying 2 grams of Compound I free base hydrate crystal form B and 6 grams of HPMC using a procedure similar to that of Example 1-1, except that 90% methanol (9:1 methanol:water) was used as the solvent for the spray drying solution.
[0069] Example 2: Preparation of tablets comprising a solid dispersion Tablet dosage forms were developed using a dry granulation process using 60% w / w amorphous solid dispersion and other excipients. The amorphous solid dispersion, microcrystalline cellulose, lactose monohydrate, silicon dioxide, and croscarmellose sodium were each de-lumped and blended. Magnesium stearate was de-lumped by sieving and blended. This constituted the intragranular blend. The intragranular blend was rotary compressed and milled to form granules. The granules, microcrystalline cellulose, lactose monohydrate, silicon dioxide, and croscarmellose sodium were each de-lumped and blended. Magnesium stearate was de-lumped by sieving and blended with the blend obtained from the previous unit operation. This constituted the tablets prepared at 12 kg scale using the weight proportions shown in Table 2 below. The tablet blend was compressed on a rotary tablet press to form tablet cores of the desired dose of drug. Tablet weights were varied to obtain different doses of drug. A different size and shape die was used for each dosage strength. The tablet cores were cosmetically coated in a pan coater.
[0070] Table 1 below shows the composition of a tablet composition of Compound I comprising the solid dispersion of Example 1.
[0071] [Table 1]
[0072] Example 3-1: Dissolution test The solid dispersions described in Example 1 were evaluated in two non-immersed dissolution tests to assess various aspects of the formulations and how they can be differentiated. The two dissolution tests evaluated include the gastric-to-intestinal (G-IB) transfer microcentrifugation dissolution test and the ultracentrifugation free drug test.
[0073] The Gastrointestinal Buffer (G-IB) transfer dissolution test is used to measure the degree of supersaturation of a drug over the solubility of the bulk drug when administered as a powder, initially in a medium with a lower pH to mimic the fasted stomach. After 30 minutes of exposure in the gastric medium, the sample is transferred to a medium with a higher pH to mimic the intestine. The drug concentration measured in this test is a mixture of free drug, drug in micelles, and drug suspended in solution as a drug / polymer colloid.
[0074] Ultracentrifugation free drug analysis is used to determine the dissolved drug species present in each formulation. This test is performed at several time points during the microcentrifugation test, namely 0, 30, 60 and 90 minutes, and consists of a centrifugation step at 300,000g which removes any colloidal species present, leaving only the free drug and drug species in micellar species. In combination with the microcentrifugation data, the content of both free drug and colloids can be determined at the time they are tested.
[0075] The G-IB dissolution test is performed similarly, but with a 30 min intragastric exposure before transfer to the intestinal medium. The intestinal medium for the G-IB dissolution test is doubly concentrated with respect to buffer and bile salts, so that after the gastric transfer step, the final pH is 6.5 and the SIF concentration is 0.5 wt%.
[0076] Microcentrifuge dissolution tests separate precipitate (undissolved drug) and total solubilized drug. Total solubilized drug consists of three solubilized species: free solubilized drug, drug associated with bile salt micelles, and drug associated with polymers (drug-polymer colloids). These three species have different activities in vivo and differentiate the formulations. Free solubilized drug is the smallest species and is the most available for absorption. Free solubilized drug can cross the unstirred mucosal boundary layer and be absorbed through the epithelium into the blood. Micelle-associated drug diffuses through the unstirred mucosal boundary layer and replenishes free drug as it is absorbed. Finally, drug-polymer colloids can also replenish free drug as it is absorbed and contribute to the effective diffusion rate. These colloids can be important depending on the rate-limiting step of absorption.
[0077] In both dissolution tests, the solid dispersion formulations exceeded the dissolution of Compound I alone with higher supersaturated solubility and better persistence.
[0078] Figures 1 and 2 show the results of the dissolution test. Figure 1 shows the dissolution data of the compositions, i.e., a solid dispersion (SD) of 1:3 Compound I free base hydrate:HPMCAS by weight (indicated as 25% HPMCAS); a solid dispersion (SD) of 1:1 Compound I free base hydrate:HPMCAS by weight (indicated as 50% HPMCAS); and a solid dispersion (SD) of 1:3 Compound I free base hydrate:HPMC by weight (indicated as hydroxypropyl methylcellulose, 25% HPMC), compared to Compound I free base hydrate alone. Error bars represent standard deviation. As shown in Figure 1, the solid dispersion of Compound I (25% HPMCAS) comprising Compound I and HPMCAS in a 1:3 weight ratio had a superior dissolution profile compared to the other compositions under these test conditions.
[0079] FIG. 2 shows the speciation data from the dissolution study. The solubility of amorphous Compound I was approximately 15 μg / mL. The free drug concentration of crystalline Compound I was comparable to that of amorphous Compound I. In contrast, the free drug concentration of Compound I in the solid dispersions ranged from 133 to 142 μg / mL. For this study, the potency of all samples was analyzed so that all formulations were tested at comparable concentrations. All solid dispersion formulations had improved free drug concentrations compared to crystalline Compound I.
[0080] Unexpectedly, it was also observed that the 25% Compound I:HPMCAS solid dispersion had a much higher concentration of drug in the form of drug-polymer colloid. In particular, a disproportionately high concentration of drug-polymer colloid in 25% Compound I:HPMCAS (529 μg / mL) was observed compared to the drug-polymer colloid concentration in 50% Compound I:HPMCAS (18 μg / mL). The colloidal species increased the drug concentration to 671 μg / mL, about 500 μg / mL higher than the free drug value. As mentioned above, it is known that drug-polymer colloids can resupply free drug as they are absorbed and contribute to the effective diffusion rate, and colloids can be important in some rate-limiting steps of absorption. Thus, it is believed that the surprisingly high concentration of drug in the form of drug-polymer colloid, in addition to the drug in free drug form, contributes to the bioavailability of Compound I.
[0081] Example 3-2: Dissolution test A solid dispersion comprising Compound I:HPMCAS in a 1:2 ratio ("33.3% HPMCAS") was prepared from 2.7 grams of Compound I free base hydrate crystal form B and 5.3 grams of HPMCAS (Shin-Etsu Chemical Co., L grade, F particle size (≦10 micron particle size)) using a procedure similar to that of Example 1. Briefly, 2 mg of test compound / mL in 0.9 mL of gastric buffer was transferred to a final dose of 1 mg / mL in 1.8 mL of 0.5% SIF in PBS, pH 6.5 at room temperature, resulting in a total volume of 1.8 mL of test solution. These samples were centrifuged at 15,800 g for 1 minute. At the designated time points, 50 μL aliquot samples were diluted 6-fold with 50 / 50 acetonitrile / water and assayed by HPLC.
[0082] The solid dispersions were evaluated using the G-IB dissolution test described in Example 3-1, along with a 25% Compound I:HPMCAS solid dispersion ("25% HPMCAS") and a 95.3% Compound I (free base hydrate, "crystalline API"), and the results are shown in Table 2.
[0083] [Table 2]
[0084] The results of the dissolution test are shown in Figure 3. Again, the solid dispersion of Compound I (25% HPMCAS) comprising Compound I and HPMCAS in a 1:3 weight ratio had a superior dissolution profile under these test conditions compared to the other compositions.
[0085] Example 4: Pharmacokinetic (PK) Study Compound I was orally administered to beagle dogs (n=3) at a dose of 10 mg / kg in various amorphous spray-dried dispersion formulations. Compound I was administered by oral gavage (PO) at a concentration of 25 mg / mL in 0.5% Methocel "A" suspension vehicle at a dose volume of 0.4 mL / kg to achieve a dose level of 10 mg / kg. "0.5% Methocel "A" suspension vehicle" was prepared by heating 30 mL of deionized water to approximately 90°C with stirring. After cooling, 0.5 g of Methocel "A" (Dow Methocel A4M Premium) was added to the water and stirred until well dispersed, followed by the addition of 70 mL of deionized water and further stirring in an ice bath. The vehicles were stored under refrigerated conditions for up to one week. Suspensions of Compound I were made by placing the solid dispersion in a mortar and adding 0.5% Methocel "A" suspension vehicle in increments, mixing with a pestle between additions. The suspension was transferred to a flask and stirred for 1 minute.
[0086] Blood samples (approximately 1.3 mL) were collected from the jugular vein into tubes containing potassium EDTA at 0.25, 0.5, 1, 2, 4, 6, 8 and 24 hours after dosing. Samples were centrifuged (10 min at 3,000 × g +4°C) and the resulting plasma was separated from the red blood cell pellet and stored at -20°C until biological analysis.
[0087] Compound I was extracted using protein precipitation. Plasma samples were thawed after storage at -20°C, and 50 μL aliquots were precipitated with 150 μL acetonitrile containing a suitable internal standard (IS), such as an analog of Compound I, such as a compound described in WO2017 / 068412. Calibration standards and quality controls were prepared in plasma and similarly extracted. All samples were centrifuged at 4700 rpm at +4°C for 20 minutes. The supernatant was analyzed using reversed-phase liquid chromatography mass spectrometry (LC-MS / MS).
[0088] Noncompartmental pharmacokinetic analysis was performed using Phoenix 6.3.0.395® (Certara USA, Inc.) software. Parameters calculated included clearance, time to maximum observed concentration (Tmax), maximum concentration (Cmax), terminal half-life, area under the curve (AUC) from time of administration to the last measurable concentration (AUC0-t), and extrapolated to infinity (AUC0-∞).
[0089] FIG. 4A shows the plasma concentration of compound I in the dog PK study of this example, and FIG. 4B shows the AUC of the test composition. The following Tables 3 and 4 show the results of the dog PK study described in this example. Table 3 summarizes the mean plasma pharmacokinetic parameters of compound I after oral administration at 10 mg / kg as a spray-dried dispersion formulation. Table 4 shows the bioequivalence of compound I after oral administration at 10 mg / kg as a spray-dried dispersion formulation in various formulations. TPGS refers to D-α-tocopheryl polyethylene glycol 1000 succinate. Comparative formulation is a non-solid dispersion formulation.
[0090] [Table 3]
[0091] [Table 4]
[0092] As shown in Table 3, the maximum exposure was obtained with the 25% HPMCAS-M batch, which showed comparable exposure to the 80% propylene glycol, 10% ethanol, 10% TPGS formulation. However, the 50% HPMCAS and 25% HPMC batches showed reduced oral exposure compared to the 25% HPMCAS-M batch and the 80% propylene glycol, 10% ethanol, 10% TPGS formulation (Table 3).
[0093] This study demonstrated that solid dispersions of Compound I comprising a 1:3 weight ratio of Compound I to HPMCAS had a desirable PK profile under these study conditions as demonstrated by plasma concentrations and AUC and C. Unexpectedly, the compositions also demonstrated smaller exposure variability as shown by the smaller error bars for the 25% HPMCAS composition compared to the 50% HPMCAS composition I in Figure 4B.
[0094] As shown in Figure 4C, the 50% HPMCAS-M and 25% HPMC test samples showed reduced oral exposure compared to both the 25% HPMCAS-M batch and the 33.33% HPMCAS-L batch. Test samples were dosed at 10 mg / Kg. Do was calculated as follows:
number
[0095] Example 5: Primate studies A total of six animals were used in a three-way (2+2+2) crossover design, with two animals receiving Compound I in powder-in-bottle (PiB) suspension in reconstitution vehicle (20 mg / kg), two animals receiving Compound I solid dispersion suspension (20 mg / kg) of Example 1, and two animals receiving Compound I in tablet form (20 mg / kg) of Example 2, on each of three dosing occasions. The reconstitution vehicle comprised propylene glycol USP 80.0% w / w; ethanol USP 10.0% w / w; vitamin E TPGS USP 10.0% w / w, totaling 100.0% w / w.
[0096] The dosing in this study was performed under fasting conditions. On the second and third dosing (days 8 and 15), the compound I formulation for administering to animals was reversed, respectively, so that all six animals finally received compound I in three different formulations (PiB in reconstitution vehicle, solid dispersion suspension, or tablet) after completing three oral doses. Solid dispersion suspension refers to a 5% suspension of the solid dispersion of Example 1 above in methocel.
[0097] Animals were closely observed for the first 12 hours after each dose and once daily on non-dosing days. Body weight was measured and recorded before dosing, and blood samples for pharmacokinetic profiling were taken for all animals at the designated time points. No clinical signs were observed as a result of compound I treatment. Compound I was orally administered three times at 20 mg / kg, 7 days apart, in the form of powder-in-bottle formulation, solid dispersion suspension, or tablet, and was well tolerated by monkeys. Prior to sample analysis, partial qualification of the method for determining the concentration of compound I in monkey plasma by LC-MS / MS was successfully performed in the dynamic assay range of 1 to 2,000 ng / mL. All plasma samples obtained in this study were analyzed by this method, and the plasma concentrations of compound I were expressed in ng / mL.
[0098] FIG. 5A shows the plasma concentration (AUClast) of Compound I in the primate PK study of this embodiment, FIG. 5B shows the plasma concentration (Cmax) of Compound I, and FIG. 5C shows the AUC (estimated) of the test composition. Error bars represent standard deviation. SD refers to solid dispersion. PiB refers to powder-in-bottle. Tablet refers to the tablet composition of Example 2 above. AUClast refers to the area under the concentration-time curve from administration (time 0) to the time of the last measured concentration (24 hours).
