DETAILED DESCRIPTION OF THE INVENTION
The present disclosure generally relates to a fixed-dose combination of pretomanid, moxifloxacin and pyrazinamide as active ingredients and optionally a fourth active ingredient such as, bedaquiline. The pharmaceutical composition can be prepared to provide easily measurable amounts for administration. The combinations herein may conveniently be presented as a pharmaceutical formulation in a unitary dosage form.
Fixed Dose Combinations
Fixed dose combinations (FDC) offer several advantages over monotherapy used in the art. Some advantages of FDC administration include enhancing patient compliance that ultimately improves treatment outcomes; reducing inadvertent medication errors and total tablet burden upon administered; preventing and/or slowing antimicrobial resistance by eliminating potential ineffective monotherapy administration; reducing drug shortages by not having to obtain multiple drug products from separate organizations; simplifying expiry date compliance (single products tend to have different expiry dates); simplifying procurement, management, and handling of drugs; and lowering production, packing, and shipping costs.
By combining pretomanid, moxifloxacin and pyrazinamide into a single dosage form, a desired daily regimen may be presented in a single dose or as two or more sub-doses per day. The pharmaceutically active compounds and combinations thereof herein may be referred to as "active ingredients", "API" or "pharmaceutically active agents." APIs described herein include pretomanid, bedaquiline, moxifloxacin, and pyrazinamide, and the pharmaceutically acceptable salts and/or solvates thereof.
Each of the APIs in the dosage forms may be present in any suitable polymorphic form, any pharmaceutically acceptable salt, and/or any suitable solvate thereof. Examples of pharmaceutically acceptable salts include salts derived from an appropriate base, such as an alkali metal (for example, sodium), an alkaline earth (for example, magnesium), ammonium and NX4+ (wherein X is Ci-C4alkyl), or an organic acid such as fumaric acid, acetic acid, succinic acid. Physiologically acceptable salts of a hydrogen atom or an amino group include salts of organic carboxylic acids such as acetic, benzoic, lactic, fumaric, tartaric, maleic, malonic, malic, isethionic, lactobionic and succinic acids; organic sulfonic acids, such as methanesulfonic, ethanesulfonic, benzenesulfonic and p-toluenesulfonic acids; and inorganic acids, such as hydrochloric, hydrobromic, sulfuric, phosphoric and sulfamic acids. Physiologically acceptable salts of a compound of a hydroxy group or carboxylic group include the anion of said compound in combination with a suitable cation such as Na+ and NX4+ (wherein X is independently selected from H or a C1-C4 alkyl group). "Alkyl" as used herein refers to a univalent group derived from a linear or branched alkane by removal of a hydrogen atom from any carbon atom (-CnFhn+i). Examples of alkyl groups include, but are not limited to, methyl, ethyl, isopropyl, sec-butyl, and n-butyl.
"Solvate" as used herein refers to a complex of variable, but defined, stoichiometry formed by a solute (the referenced compound) and a solvent. Solvates should be understood not to include solid forms of a reference compound containing sub-stoichiometric amounts of residual solvents. Solvents, by way of example, include water (such can be referred to as a "hydrate"), methanol, ethanol, isopropyl alcohol, ethyl acetate, ethylene glycol, propylene glycol, acetonitrile, dimethyl sulfoxide, N,N- dimethylformamide, and acetic acid, among others. The phrase "salt and/or solvate" refers to each of a salt (e.g., moxifloxacin hydrochloride), a solvate, and a solvate of a salt (e.g., moxifloxacin hydrochloride monohydrate).
Pretomanid (also known as "Pa") is a novel nitroimidazole anti-bacterial agent recently approved by the U.S. FDA as a TB therapy, and having many attractive characteristics - most notably its novel mechanism of action, its activity in vitro against all tested drug-resistant clinical isolates, and its activity as both a potent bactericidal and a sterilizing agent. In addition, the compound shows no evidence of mutagenicity in a standard battery of genotoxicity studies, no significant cytochrome P450 interactions, and no significant activity against a broad range of Gram-positive and Gram-negative bacteria. The lUPAC designation for pretomanid is (6S)-2-nitro-6-{[4-(trifluoromethoxy)benzyl]oxy}-6,7-dihydro-5H- imidazo[2,l-b][l,3]oxazine. Pretomanid is a BCS class ll/IV compound that demonstrates poor solubility but high permeability which can result in solubility-limited absorption.
Moxifloxacin (l-cyclopropyl-7-[(lS,6S)-2,8-diazabicyclo[4.3.0]nonan-8-yl]-6-fluoro-8-methoxy-4- oxoquinoline-3-carboxylic acid, also referred herein as "M") is a synthetic fluoroquinolone antibacterial agent developed by Bayer AG (initially called BAY 12-8039). It is currently marketed worldwide (as the hydrochloride salt, often as the monohydrate of the hydrochloride salt) under the brand names AVELOX, AVALOX and AVELON for oral treatment. Herein, unless otherwise noted, "moxifloxacin" refers to the free base as well as a pharmaceutically acceptable salt and/or solvate thereof, such as moxifloxacin hydrochloride and/or moxifloxacin hydrochloride monohydrate.
Pyrazinamide (pyrazine-2-carboxamide, also referred herein as "Z") is the pyrazine analogue of nicotinamide and is used as an anti-tuberculous agent. Pyrazinamide is most commonly used for treatment of active tuberculosis (TB) during the initial phase of therapy (generally the first two months of treatment), in combination with other agents. Pyrazinamide demonstrates clinically significant antibacterial activity against Mycobacterium tuberculosis and M. africanum.
Bedaquiline ((aS^R)-6-Bromo-a-[2-(dimethylamino)ethyl]-2-methoxy-a-l-naphthalenyl^- phenyl-3-quinolineethanol; also known herein as "B"). Bedaquiline is marketed as SIRTURO” and specifically inhibits mycobacterial ATP (adenosine 5'-triphosphate) synthase, by binding to subunit c of the enzyme that is essential for the generation of energy in Mycobacterium tuberculosis. Herein, unless otherwise noted, "bedaquiline" refers to the free base as well as a pharmaceutically acceptable salt and/or solvate thereof, such as bedaquiline fumarate.
The amount of each active ingredient that may produce a single dosage form may vary depending upon the host treated and the particular mode of administration. A convenient unitary dosage formulation may contain each of the active ingredients in any amount from 1 mg to 1 g each, for example but not limited to, 10 mg to 500 mg for each active ingredient. Daily dosages of the active ingredients in such an embodiment can be, for example 50-2000 mg pyrazinamide, 10 - 800 mg moxifloxacin, 10 - 400 mg pretomanid, and 10 - 400 mg bedaquiline. In certain embodiments, the daily dosages of the active ingredients can be 1500 mg pyrazinamide, 400 mg moxifloxacin, 200 mg pretomanid, and 100 or 200 mg bedaquiline, when present. Each of the preceding amounts of APIs can be understood to refer to the amount of the API free base, where an equivalent amount of a pharmaceutically acceptable salt and/or solvate may be used in place of a free base form.
In certain embodiments, a total daily dose of Pa, M and Z can be included in more than one unit dosage that could be ingested comfortably. For example, the total daily dose of each active agent may be equally divided among two or more unit dosages to facilitate daily dosing. In another embodiment, the total daily dose of each active agent is equally divided among two to six unit dosages, or two to five unit dosages, or two to four unit dosages, or two, or three, or four, or five, or six unit dosage. In each instance, the plurality of unit dosages comprising the total daily dose can be administered together simultaneously or sequentially to provide the total daily dose to the patient in need thereof. In several examples, a total daily dose of 200 mg Pa, 400 mg M, 1500 mg Z and optionally, 200 mg or 100 mg B, may be equally divided among several unit dosages according to any one of the following embodiments: The several unit doses noted above may be administered together to a person in need thereof to provide the total daily dose. In one embodiment, each of the three unit dosages can contain 80.6 mg of bedaquiline fumarate, 152 mg of moxifloxacin hydrochloride monohydrate, 66.7 mg of pretomanid and 500 mg of pyrazinamide as active ingredients to provide the total daily dose.
Pharmaceutical formulations containing the active ingredients may be in any form suitable for the intended method of administration. When used for oral use for example, tablets, troches, lozenges, aqueous or oil suspensions, dispersible powders or granules for oral suspension, sachets, emulsions, hard or soft capsules, syrups or elixirs may be prepared (see, for example, Remington's Pharmaceutical Sciences (Mack Publishing Co., Easton, Pa.)).
In certain embodiments, the FDCs described herein can encompass solid dosage forms such as monolithic tablets, multi-layer tablets, and combinations thereof. A monolithic approach may involve an intimate contact between two or more of the different APIs (active pharmaceutical ingredients), such as by blending and/or granulating the different APIs together; or may involve blending of two or more granulates, each prepared to contain one or more APIs.
In one embodiment, a formulation may be in the form of a monolithic tablet that contains Pa, M, Z, and optionally B. For example, each of the preceding APIs may be separately granulated, and the granulates of the individual APIs may be blended together with optional extragranular excipients to provide the monolithic tablet.
In another embodiment, a formulation may be in the form of a bilayer tablet, for example, that contains a first layer that contains M and Z and a second layer that contains Pa and optionally B. For example, each of the preceding APIs may be separately granulated, and the granulates of the individual APIs may be blended together with optional extragranular excipients to provide the layers of a bilayer tablet. "Bilayer" as used herein means two chemically distinct domains that are in physical contact to form a unitary dosage form. For example, bilayer includes two domains that are either vertically or horizontally arranged stacked or in a core-shell arrangement.
When granulated, each API granulate comprises the respective API and one or more intragranular excipients. Suitable intragranular excipients include, but are not limited to, one or more diluents, binders, surfactants, disintegrants, and mixtures thereof. Examples of intragranular excipients are described further below.
For the preparation of oral solid dosage forms, such as tablets, the API granulates may be combined with suitable extragranular excipients prior to tableting. Where a bilayer tablet is prepared, each layer may independently contain extragranular excipients, i.e., a first layer can contain first extragranular excipients, and a second layer can contain second extragranular excipients. Each extragranular excipient can be selected, independently, from the group consisting of a diluent, a disintegrant, a glidant, a lubricant, a coloring agent, a sweetener, a flavoring, an antioxidant, a preservative, and mixtures thereof. Examples of extragranular excipients are described further below.
In one example, for the preparation of powder for oral suspension, extragranular excipients may be include, one or more diluents (fillers), sweeteners, binders, suspending (thickening) agents, buffers, glidants, flavorings, or coloring agents. Suitable suspending agents include, for example, hydrocolloid gums such as xanthan gum, guar gum, locust bean gum, gum tragacanth, veegum, sodium alginate, and the like. Alternatively, synthetic suspending agents may be used such as sodium carboxymethylcellulose, polyvinylpyrrolidone, hydroxypropylcellulose and the like. The amount of the suspending agent used in the powder for oral suspension compositions may be in the range of from about 0.1% to about 10% w/w based on the total weight of the powder for oral suspension.
Diluents can include pharmaceutically acceptable inert fillers such as, but are not limited to, inorganic fillers such as calcium carbonate, dibasic calcium phosphate(such as anhydrous or dihydrate forms, e.g., Emcompress® Calcium Phosphates (JRS PHARMA GmbH & Co.

Formulation Process
As noted above, each of the APIs may be separately granulated with intragranular excipients, or two of the APIs may be granulated together with intragranular excipients to provide a plurality of granulates. That is, a pretomanid granulate ("Pa granulate"), a bedaquiline granulate ("B granulate"), a moxifloxacin granulate ("M granulate"), and/or a pyrazinamide granulate ("Z granulate") may be prepared. Examples of combination granulates include a pretomanid and bedaquiline granulate ("B+Pa granulate") and a moxifloxacin and pyrazinamide granulate ("M+Z granulate"). In one particular embodiment, a Pa granulate and a M+Z granulate are prepared. In another embodiment, a B granulate, a Pa granulate, and a M+Z granulate are prepared. In another embodiment, a B+Pa granulate and a M+Z granulate are prepared.
In certain embodiments, the following sets of granulates may be prepared, where individual granulates are separated by commas and combination granulates are joined by "+":
Each granulation may be according to a wet or dry granulation process in the presence of a suitable binder, as is familiar to those skilled in the art. Where a dry granulating process is utilized (e.g., blending and slugging of the dry components), the binder may comprise a dry binder such as pre gelatinized starch, anhydrous lactose, dibasic calcium phosphate, or a mixture thereof. When a wet granulation process is utilized, the APIs and intragranular excipients may be granulated together using a solution (e.g., a solution comprising a wet binder and, optionally, a surfactant). Examples of wet binders include, pre-gelatinized starch, povidone (e.g. Povidone K30), methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, hydroxypropyl methylcellulose (HPMC), and mixtures thereof. In certain embodiments, povidone (e.g. Povidone K30), hydroxypropyl methylcellulose (HPMC), or a mixture thereof may be used as a wet binder.
In either case, the prepared API granulate may be sized and/or dried to a suitable wt.% residual solvent and/or water and particle size distribution. Sizing may be through one or more reduction processes, such as sieving and/or milling to provide a sized API granulate having a desired particle size distribution. Drying and sizing can be in any suitable order depending on the properties of the granulate. For example, a granulate prepared by wet granulation may be wet milled prior to drying. In another example, a wet granulate may be dried followed by dry milling and/or sieving.

Referring to Figure 1, a process is exemplified for the preparation of the API granulates. Therein, a selected API (100) or combination of APIs and intragranular excipients (101) are sifted through a suitable sized screen (e.g., through 20 or 30 ASTM). Separately, a granulation solution (121) comprising a wet binder and an optional surfactant in a solvent (e.g., water) is prepared. The sifted materials are wet granulated (120) with the granulation solution (121), for example, by a top spray granulation process or in a rapid mixer granulator. The resulting granules are processed (130) to provide the API granulate (140) having a desired residual solvent content and/or particle size distribution. As shown in Figure 1, examples of API granulates that may be prepared include B granulates, Pa granulates, and M+Z granulates.
Processing (130) may include one or more drying and/or particle size reduction processes in a suitable order, as discussed above. For example, the granules may be dried to a desired residual solvent content, and the particle size of the dried granules may be reduced by sifting through a suitable screen (e.g., through #25 ASTM screen) followed by milling the retention through a second suitable screen (e.g., a 40G screen via a co-mill). In another example, the granules may be wet milled (e.g., in a Quadro Co mil fitted with 250 Q screen), the milled granules dried (e.g., in a fluidized bed dryer at an inlet air temperature of 50°C until loss on drying (LOD) of no more than (NMT) 2.0% w/w is achieved), and the dried granules sifted through a suitable screen (e.g., through a Quadro Co mil fitted with an 50G screen).
Such API granulates may be used to prepare a variety of oral unit dosage forms, including, but not limited to, monolayer tablets, bilayer tablets, filled hard capsules, and sachets containing powders for oral suspension. Oral unit dosage forms may be prepared by combining one or more API granulates with one or more extragranular excipients to provide a blend. In the preparation of tablets, a portion of the blend may be compressed into a tablet. Such tablets may optionally contain a coating layer over an outer surface of the tablet. Oral unit dosage forms herein may comprise about 60 - 99 w/w % API granulates (i.e., the sum of all API granulates present) and about 1 - 40 w/w % extragranular excipients; or 70 - 99 w/w % API granulates (i.e., the sum of all API granulates present) and about 1 - 30 w/w % extragranular excipients; 80 - 99 w/w % API granulates (i.e., the sum of all API granulates present) and about 1 - 20 w/w % extragranular excipients. For example, the tablets herein may comprise about 85 - 95 w/w % API granulates and about 5 - 15 w/w % extragranular excipients; or about 90 - 95 w/w % API granulates and about 5 - 10 w/w % extragranular excipients.

Following blending, an optional lubricant (231), such as magnesium stearate that has been sifted through #60 ASTM, may be added and blending (230) continued to yield a blend. A desired portion of the blend may be compressed (240) to provide tablets that may be optionally coated (250) with a coating layer (e.g., an OPADRY coating) to provide the monolayer tablets (260).
Referring to Figure 2b, a process is exemplified for the preparation of monolayer tablets from the preceding API granulates. Therein, when present, extragranular excipients (201) are sifted (210) through a suitable sized screen (e.g., through 30 # ASTM) and blended (220) with one or more additional API granulates (221, 222, and/or 225).

The optional film coating agents may, for example, comprise cellulose derivatives such as methyl cellulose (MC), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), methacrylic acid/acrylate copolymers, hydroxypropyl methylcellulose (HPMC), vinyl polymers or natural film formers, such as shellac. Examples of commercially available film formers include, but are not limited to, OPADRY (HPMC), OPADRY II (poly(vinyl alcohol)), and SURELEASE (Ethylcellulose Dispersion Type B NF) Film Coating Systems (each available from Colorcon, Inc., North Wales, Pennsylvania), and mixtures thereof.
