Description

Pharmaceutical formulations of triazoles and methods of making the same

[0001] Reference to Related Applications

[0002] This application claims priority to and the benefit of Chinese Patent Application No. 202411391209.5, filed September 30, 2024, in the State Intellectual Property Office of the People’s Republic of China, the entire contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0003] The present application relates to the field of medicine, in particular to pharmaceutical compositions comprising triazoles, formulations, methods of making the same and uses thereof. BACKGROUND

[0004] Compound 1 is a urate transporter 1 (URAT1) inhibitor, which has the chemical formula of Formula (I) below, and its chemical name is 2-((5-bromo-4-(2-chloro-4-cyclopropyl naphthalenyl-1-yl)-4H-1,2,4-triazol-3-yl)-thio)acetic acid. The structure, crystal form and preparation method of Compound 1 can be found in WO2017215589A1, WO2019114838A1, WO2021249468A1, etc.

[0005] AstraZeneca’s first targeted URAT1 inhibitor, Lesinurad, was approved by FDA in December 2015, and its 200 mg / day dose was approved to be used in combination with xanthine oxidase inhibitors XOI (such as Febuxostat, etc.) for the treatment of hyperuricemia and gouty arthritis, but the additional effect of the combination drug compared with the use of xanthine oxidase inhibitors alone is not very significant. At the same time, the 400 mg / day dose of Lesinurad was not approved due to the significant increase in side effects observed at high doses (higher incidence of kidney-related adverse events, especially kidney stones), although the combination drug at high doses showed higher additional effects. Therefore, FDA required that the Lesinurad label add a black box warning to warn medical staff that Lesinurad can cause acute kidney failure, especially more common when not used in combination with XOI, and the risk of kidney failure is higher if Lesinurad is used at an unapproved dose. At the same time, the U.S. FDA required AstraZeneca to continue to investigate the safety of the kidneys and cardiovascular system after the marketing of Lesinurad.

[0006] CN112057429A discloses a controlled-release drug composition for retinal, overcoming the serious toxic side effects of existing retinal when used at high doses; CN107281108A discloses a solid dispersion containing retinal in an amorphous form, which increases dissolution and stability; CN108324695A discloses a retinal-coated tablet, wherein the retinal content in the coated tablet is 67 mg / tablet.

[0117] For the purposes of the present application, the following terms used in the specification and claims have the meanings indicated below, unless stated otherwise.

[0118] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

[0119] The word "comprise" or "comprising" and its variations such as "comprises" or "comprising", are to be construed in an open, non-exclusive sense, i.e. in the sense of "including, but not limited to".

[0120] Unless specifically defined otherwise, all ratios (including percentages) or parts used herein are by weight.

[0121] The term "pharmaceutically acceptable" is used in reference to those compounds, materials, compositions, and / or dosage forms that are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit / risk ratio.

[0122] The term "pharmaceutical composition" refers to a mixture of one or more active ingredients of the present disclosure with a pharmaceutically acceptable excipient. The purpose of a pharmaceutical composition is to facilitate administration of a compound of the present disclosure to a subject.

[0123] In the present context, when referring to a compound of formula (I) or a pharmaceutically acceptable salt thereof, this is to be understood as meaning the amount of the compound of formula (I).

[0124] The compounds of formula (I) can be administered in the form of their free bases, but they can also be administered in the form of their salts, solvates and prodrugs, which are converted into the free base form of the compounds of formula (I) in the body. For example, pharmaceutically acceptable salts of the compounds of formula (I) are within the scope of the present application and can be obtained from different organic and inorganic acids as is known in the art.

[0125] In some embodiments, the pharmaceutically acceptable salts of the compounds of Formula (I) of the present application refer to salts of the compounds of the present application, prepared from the compounds of the present application and either an acid or a base, which are not toxic to the subjects to which the compounds of the present application are administered. When the compounds of the present application contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base to produce the salt. Pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amino, or magnesium salt, or a similar salt. When the compounds of the present application contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid to produce the salt. Examples of pharmaceutically acceptable acid addition salts include salts of mineral acids, such as hydrochloric, hydrobromic, nitric, carbonic, bicarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, hydrogensulfuric, hydroiodic, phosphorous, and the like; salts of organic acids, such as acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric, and methanesulfonic acids, and the like; salts of amino acids, such as arginine and the like; and salts of organic acids, such as glucuronic, and the like (see Berge et al., "Pharmaceutical Salts", Journal of Pharmaceutical Science 66: 1-19 (1977)). Certain specific compounds of the present application contain both basic and acidic functionalities and, as such, are capable of conversion into either base or acid addition salts.

[0126] Preferably, the salts are contacted with a base or an acid in a conventional manner to re-isolate the parent compound, thereby regenerating the neutral form of the compound. The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents.

[0127] As used herein, "pharmaceutically acceptable salts" are derivatives of the compounds of the application wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic groups such as amines, alkali or organic salts of acidic groups such as carboxylic acids, and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound which are formed, for example, from non-toxic inorganic or organic acids. The conventional non-toxic salts include, but are not limited to, those derived from inorganic and organic acids selected from 2-acetoxybenzoic acid, 2-hydroxyethanesulfonic acid, acetic acid, ascorbic acid, benzenesulfonic acid, benzoic acid, bicarbonate, carbonic acid, citric acid, edetic acid, ethane disulfonic acid, ethanesulfonic acid, fumaric acid, gluconic acid, glutamic acid, glycolic acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, hydroxynaphthoic acid, isethionic acid, lactic acid, lactose, lauryl sulfonic acid, maleic acid, malic acid, mandelic acid, methanesulfonic acid, nitric acid, oxalic acid, pamoic acid, pantothenic acid, phenylacetic acid, phosphoric acid, polygalacturonic acid, propionic acid, salicylic acid, stearic acid, subacetic acid, succinic acid, sulfamic acid, sulfanilic acid, sulfuric acid, tannic acid, tartaric acid, and p-toluenesulfonic acid.

[0128] The pharmaceutically acceptable salts of the present application can be synthesized from the parent compound that contains an acid or a base moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two. Generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile, among others, are preferred.

[0129] It is noted that the crystalline and amorphous forms of the compounds can be identified by conventional means, including X-ray diffraction spectroscopy (XRD), differential scanning calorimetry (DSC) measurements, and the like. In X-ray diffraction spectroscopy (XRD), the diffraction pattern obtained from a crystalline compound is often characteristic for a particular crystal form, where the relative intensities of the bands can vary due to preferred orientation effects resulting from differences in crystallization conditions, particle size, and other measurement conditions. Thus, the relative intensities of the diffraction peaks are not characteristic of a particular crystal form, and it is the relative positions of the peaks, rather than their relative intensities, that should be noted in comparing a crystal form with a known crystal form. Furthermore, for any given crystal form, there can be slight errors in the position of the peaks, which are well known in the art of crystallography. For example, the position of the peaks can shift due to variations in temperature during sample analysis, sample movement, or instrument calibration, and the measurement error in 2Θ is typically ±0.2°. Thus, this error should be taken into account in determining each crystal structure. In XRD patterns, the position of the peaks is usually given in terms of the 2Θ angle or the interplanar spacing d, which are related by the simple conversion: d = λ / 2 sin Θ, where d represents the interplanar spacing, λ represents the wavelength of the incident X-rays, and Θ is the diffraction angle.

[0130] Differential scanning calorimetry (DSC) measures the transition temperature when a crystal absorbs or releases heat as its crystal structure changes or the crystal melts. For the same crystalline form of the same compound, the thermal transition temperature and melting point are typically within about 5°C, usually within about 3°C, in successive analyses, and when we say that a compound has a given DSC peak or melting point, we mean the DSC peak or melting point ± 5°C. DSC provides a useful method for distinguishing between different crystalline forms. Different crystalline forms can be identified by their different transition temperature profiles. It is noted that for mixtures, the DSC peak or melting point can vary over a larger range. In addition, because decomposition can occur during melting of a substance, the melting temperature is closely related to the rate of temperature increase.

[0131] The term "administering" or "administration" means physically introducing a composition comprising an active compound into a subject or patient or subject using any of a variety of methods and delivery systems known to those skilled in the art. In certain embodiments, oral administration is used.

[0132] "Unit dosage" or "unit dose" means the preparation of a formulation packaged in a single container, e.g., "a formulation in unit dosage form" means each tablet. "A pharmaceutical composition in unit dosage form contains 25 mg of a compound of Formula (I)" means that each tablet in the final preparation contains 25 mg of a compound of Formula (I).

[0133] "Patient," "subject," or "host" means a mammal, preferably a human.

[0134] "Therapeutically effective amount" means the amount of a compound that, when administered to a human for treating a disease, is sufficient to effect treatment for that disease.

[0135] "Treatment" means any administration of a therapeutically effective amount of a compound, and includes:

[0136] (1) inhibiting the disease in an individual who is experiencing or displaying the pathology or symptomatology of the disease (i.e., arresting further development of the pathology and / or symptomatology), or

[0137] (2) effecting an improvement in the pathology and / or symptomatology of the disease in an individual who is experiencing or displaying the pathology or symptomatology of the disease (i.e., reversing the pathology and / or symptomatology).

[0138] For purposes of description and disclosure, all patents, patent applications, and other publications identified herein are expressly incorporated herein by reference. Any reference to such publications is not intended to limit the scope of the disclosure to the specific disclosure contained therein.

[0164] Table 3 Composition of prescription 1 and prescription 2

[0165] Prescription 1 and prescription 2 both use wet granulation process, and are tabletted after mixing with additional excipients. The active pharmaceutical ingredients (API) used are all sieved through 60 mesh. When prescription 1 is operated, the binder hydroxypropyl methyl cellulose E5 is dry added, and the granulation effect is loose. Prescription 2 uses the binder hydroxypropyl methyl cellulose E5 to prepare an aqueous solution before adding. The dissolution and stability of the two prescriptions are investigated.

[0166] The results of the content detected at 0 days are shown in Table 4 below:

[0167] Table 4 Research content results of prescription 1 and prescription 2

[0170] The results of the related substance test showed that there was no significant difference between the two formulations at 0 days and 7 days of acceleration. From the results of the open and closed, moisture had no effect on the impurities.

[0171] Dissolution conditions: According to the solubility of the drug in different pH buffers, pH 4.5 acetate buffer that meets the sink conditions is selected as the dissolution medium for formulation screening. The dissolution method is to maintain 37 ± 0.5°C, pH 4.5 acetate buffer 900 mL as the medium, slurry method 50 rpm, 60 min 250 rpm, and the dissolution curve of the drug within 90 min is investigated. The dissolution results of 0 days and 7 days of acceleration are as follows:

[0188] The samples of sieving, grinding and micronization of API were detected for crystal form to investigate the influence on the crystal form of API. The samples of crushed material after granulation and total mixing and the finished product after tabletting were detected for crystal form to investigate the influence of the granulation and tabletting process on the crystal form of API. The results are shown in Figures 1-3.

[0189] The results show that the processes of grinding, sieving, micronization and wet granulation and tabletting do not affect the crystal form of the drug.

[0190] The results of content detection are shown in the following table 12:

[0191] Table 12 Content detection results of prescription 4 study

[0192] The results of related substance detection of prescription 3 and prescription 4 are shown in the following table 13:

[0194] The results of related substance detection showed that there was no significant difference between the two formulations of 0 days and accelerated 7 days, and the open, sealed and sealed with desiccant conditions had no effect on the related substances.

[0195] Dissolution conditions: According to the solubility of the drug in different pH buffers, pH 4.5 acetate buffer that meets the sink conditions is selected as the dissolution medium for formulation screening. The dissolution method is to maintain 37 ± 0.5℃, pH 4.5 acetate buffer 900mL as medium, slurry method 50rpm, 60min 250rpm, to investigate the dissolution curve of the drug within 90min. The dissolution results of 0 days and 7 days accelerated are shown in the following table:

[0196] Table 14 Dissolution results of formulation research at room temperature for 0 days and 7 days accelerated

[0197] The dissolution results showed that the dissolution without desiccant was slightly decreased, and there was no difference between 0 days and desiccant samples, and there was no significant difference compared with the first three formulations, and API micronization could not improve the in vitro dissolution.

[0198] Example 4

[0199] The preparation method of prescription 5 and prescription 6 is the same as prescription 4.

[0200] Table 15 Composition of prescription 5 and prescription 6

[0201] Prescription 5 and prescription 6 are 25mg and 100mg specifications respectively. The two specifications are enlarged in equal proportion. The prescription process is wet granulation drying and then mixed with additional excipients and pressed into tablets. The content uniformity, dissolution and stability of the samples are investigated.

[0202] The detection results of content uniformity are as follows in table 16:

[0203] Table 16 Determination results of content uniformity of different formulations

[0204] The results of related substance detection of pre-stability samples are shown in the following table 17:

[0205] Table 17 Results of related substance detection

[0206] The results of related substances showed that there was no significant difference in related substances between the two formulations under the conditions of 0 days sealing and accelerated conditions.

[0207] Dissolution condition: According to the solubility of the drug in different pH buffer, pH 5.5 acetate buffer was selected as the dissolution medium for 100 mg sample to meet the sink condition. In order to unify the dissolution medium and facilitate comparison with small sample, pH 4.5 acetate buffer was selected as the medium for 25 mg sample at 0 day and pH 5.5 acetate buffer was selected as the medium. The dissolution method was as follows: 900 mL of pH 5.5 (pH 4.5) acetate buffer was used as the dissolution medium, the slurry method was used at 50 rpm, and the speed was increased to 250 rpm after 60 min. The dissolution curve of the drug within 90 min was investigated. The dissolution results are shown in the following table:

[0208] Table 18 Dissolution results of prescription 5 room temperature 0 day and accelerated sample

[0209] Table 19 Dissolution results of prescription 6 0 day and accelerated sample

[0210] The dissolution results show that when pH 5.5 acetate buffer is used as the dissolution medium, the dissolution of the 25 mg sample is significantly accelerated and completely dissolved. The dissolution of the 100 mg sample is still significantly improved after the speed is increased at 60 min, and the dissolution degree is improved. Therefore, the dissolution medium is considered to be replaced.

[0211] Dissolution condition: 900 mL of pH 6.0 phosphate buffer was selected as the medium, 37±0.5℃ was maintained, the slurry method was used at 50 rpm, and the speed was increased to 250 rpm after 60 min. The dissolution curve of the drug within 90 min was investigated. The dissolution results are shown in the following table:

[0212] Table 20 Dissolution results of prescription 6 0 day

[0213] The dissolution results show that after the dissolution medium is replaced, the dissolution rate of the 100 mg sample is significantly accelerated and completely dissolved. Therefore, the unified dissolution condition for different sizes is determined as follows: 900 mL of pH 6.0 phosphate buffer is used as the medium, 37±0.5℃ is maintained, the slurry method is used at 50 rpm, and the speed is increased to 250 rpm after 60 min. The dissolution curve of the drug within 90 min is investigated.

[0214] Based on the above results, wet granulation and boiling drying are selected. The related substances basically meet the requirements, and pH 6.0 phosphate buffer is selected as the dissolution medium, which can be completely dissolved.

[0307] 7 Results

[0308] (1) Safety and tolerability

[0309] In Part 1 study, 22 AEs occurred in 14 subjects (36.8%) of Compound 1 group, all were TEAEs, among which 17 AEs occurred in 12 subjects (31.6%) were related to study drug; 5 TEAEs occurred in 4 subjects (44.4%) of placebo group, among which 4 AEs occurred in 4 subjects (44.4%) were related to study drug. The common (incidence ≥5.0%) TEAEs in Compound 1 group included: elevated urine beta 2 microglobulin (4 subjects 4 events, 10.5%), decreased blood pressure (3 subjects 5 events, 7.9%), positive urine leukocyte (2 subjects 2 events, 5.3%), rash (2 subjects 2 events, 5.3%), mouth sores (2 subjects 2 events, 5.3%), diarrhea (2 subjects 2 events, 5.3%).

[0310] In Part 2 study, 32 AEs occurred in 18 subjects (75.0%) of Compound 1 group, all were TEAEs, among which 31 AEs occurred in 18 subjects (75.0%) were related to study drug; 2 TEAEs occurred in 2 subjects (33.3%) of placebo group, among which 2 AEs occurred in 2 subjects (33.3%) were related to study drug. The most common (incidence ≥5.0%) TEAEs in Compound 1 group included: positive urine leukocyte (5 subjects 7 events, 45.8%), elevated urine beta 2 microglobulin (3 subjects 3 events, 12.5%), elevated serum creatinine (3 subjects 3 events, 12.5%), elevated pulse in arms (3 subjects 3 events, 12.5%), mouth ulcers (3 subjects 3 events, 12.5%), diarrhea (2 subjects 2 events, 8.3%).

[0311] (2) Pharmacokinetic results

[0312] The mean plasma concentration-time curves of Compound 1 in each dose group of Part 1 study were shown in Figure 4. As can be seen from the plasma concentration-time curve, after single oral administration, Compound 1 was rapidly absorbed in human body, and the peak time was about 1.5-3.5 h, and then the plasma concentration value rapidly decreased. With the increase of the dose, the plasma drug concentration increased. Compared with fasting administration, the peak time was later and the peak concentration was higher after meal administration. The pharmacokinetic parameters were shown in Table 3.2.

[0313] Power model analysis, AUC 0-24h The 90% CI was (1.0255, 1.1885), which was out of the linear reference interval (0.9298, 1.0702), indicating that the plasma AUC was not linearly proportional to the dose in the dose range. According to the slope 1.1070, the proportion of increase in plasma exposure level was slightly higher than that of dose increase. In addition, C maxThe 90% CI of (0.9469, 1.0636) of AUC max The increase ratio was linear to the dose. The non-parametric test (Kruskal-Wallis test) showed that there was no significant difference in T max There was no significant difference.

[0314] The variance analysis of the effect of food on pharmacokinetics showed that the AUC 0-∞ , AUC 0-t , and C max of the fasting group and the postprandial group had statistical significance. It was proved that food had an effect on the plasma drug exposure level of Compound 1. The T max of the postprandial group was slightly longer than that of the fasting group, which showed that the postprandial administration might delay the peak time of the plasma drug concentration. max

[0315] In the Part 2 study, the average plasma drug concentration-time curve of each dose group is shown in the following Figure 5. After the first administration, Compound 1 was quickly absorbed in the human body, and the peak time was about 2.28-3.06 h, and then the plasma concentration value rapidly decreased. With the increase of the dose, the plasma drug concentration increased. The plasma concentration curve after the oral administration once a day for 7 consecutive days was similar to that of the first administration. After the first oral administration, the data were basically consistent with the plasma pharmacokinetic parameter data of the corresponding respective dose groups in the Part 1 study. The specific information is shown in Table 3.3.

[0316] Table 3.3 Summary of pharmacokinetic parameters (Mean ± SD) (Part 2 study)

[0317] The above data showed that the pharmacokinetic parameters of each dose group after 7 days of continuous administration were similar to those of the first day. The non-parametric test (Kruskal-Wallis test) showed that there was no significant difference in T max . The Power model analysis showed that the 90% CI of AUC 0-24h,ss , C max , ss was (1.1649, 1.5030) and (1.1147, 1.5284), respectively, both of which fell outside the linear reference interval (0.8390, 1.1610), which indicated that the C max and AUC were not in proportion to the dose in the dose range. According to the slopes 1.3340 and 1.3216, it was suggested that the increase ratio of the plasma exposure and the peak concentration level was more than the increase ratio of the dose.

[0318] 9CONCLUSION​

[0319] The severity of all TEAEs in Compound 1 group and placebo group was grade 1. No TEAEs leading to study drug discontinuation, TEAEs leading to subject withdrawal, and SAEs occurred. Compound 1 was well tolerated and safe. The plasma pharmacokinetic parameters showed that Compound 1 was rapidly absorbed after single dose, and the time to peak concentration occurred at about 1.50-3.59 h after administration. Within the dose range of 25-600 mg, the plasma drug exposure increased with the dose, and no absorption saturation occurred at the highest dose. The clearance rate of Compound 1 was moderate, and the elimination half-life was about 6.46-9.03 h. No accumulation occurred after once-daily, 7-day consecutive oral administration of Compound 1 at 100-400 mg in the fasted state. The accumulation index was about 0.99-1.10; the AUC 1 / 2 The accumulation index was about 0.99-1.10; the AUC max The accumulation index was about 0.99-1.10; the AUC 0-24h The accumulation index was about 0.99-1.10; the AUC max The accumulation index was about 0.99-1.10; the AUC
