The present invention relates to oral tablet compositions of a GLP-1 receptor agonist, 3-[(lS,2S)-l-[5-[(4S)-2,2-dimethyloxan-4-yl]-2-[(4S)-2-(4-fl uoro-3,5- dimethylphenyl)-3-[3-(4-fluoro-l-methylindazol-5-yl)-2-oxoim idazol-l-yl]-4-methyl-6,7- dihydro-4H-pyrazolo[4,3-c]pyridine-5-carbonyl]indol-l-yl]-2- methylcyclopropyl]-4H- l,2,4-oxadiazol-5-one (herein, GLP1RA), or a pharmaceutically acceptable salt thereof. Compositions disclosed herein can be useful for the treatment of type 2 diabetes mellitus (T2D) and in weight management.

Diabetes mellitus is a chronic disorder characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. In T2D, the combined effects of impaired insulin secretion and insulin resistance are associated with elevated blood glucose levels. T2D is an increasingly prevalent disease that frequently leads to declining health and quality of life for patients. Effective oral treatments to manage T2D and/or for use in weight management are desired.

GLP1RA, that is, 3-[(lS,2S)-l-[5-[(4S)-2,2-dimethyloxan-4-yl]-2-[(4S)-2-(4- fluoro-3,5-dimethylphenyl)-3-[3-(4-fluoro-l-methylindazol-5- yl)-2-oxoimidazol-l-yl]-4- methyl-6,7-dihydro-4H-pyrazolo[4,3-c]pyridine-5-carbonyl]ind ol-l-yl]-2- methylcyclopropyl]-4H-l,2,4-oxadiazol-5-one, or a pharmaceutically acceptable salt thereof, is described and claimed in US10,858,356. The US10,858,356 patent generally describes oral compositions.

GLP1RA may be prepared as a pharmaceutically acceptable salt. One salt of GLP1RA is a hemi-calcium hydrate, 3-[(lS,2S)-l-[5-[(4S)-2,2-dimethyloxan-4-yl]-2- [(4S)-2-(4-fluoro-3,5-dimethylphenyl)-3-[3-(4-fluoro-l-methy lindazol-5-yl)-2- oxoimidazol-l-yl]-4-methyl-6,7-dihydro-4H-pyrazolo[4,3-c]pyr idine-5-carbonyl]indol-l- yl]-2-methylcyclopropyl]-4H-l,2,4-oxadiazol-5-one, 0.5 Ca hydrate, (herein “GLP1RA- Ca”) with the structure as shown below.

GLP1RA is a poorly permeable and poorly soluble weak acid with a pKa of 5.1. GLP1RA has very low aqueous solubility across the physiologic pH range as well as in simulated physiological fluids. GLP1RA and its pharmaceutically acceptable salts are observed to have a strong pH dependent solubility profile contributing to challenges such as variability in absorption and consequently in pharmacokinetic performance and potential food effects. There is a desire for GLP1RA, including but not limited to, GLPIRA-Ca, tablet compositions providing reliable PK performance in a patient friendly dosage form, with minimal potential for drug-drug interactions and reduced or no food effects. A GLP1RA composition to enhance solubility and dissolution rate of the active substance in a tablet dosage form may be desired. A pharmaceutically elegant dosage form to deliver an effective amount of active GLP1RA to the targeted portion of the gastrointestinal tract, while small enough to facilitate patient swallowing is desired.

Compositions described herein provide desired properties. In an aspect, the use of a sprayed dried dispersion (SDD) of the GLP1RA, or a pharmaceutically acceptable salt thereof, together with a pH modifier, as described herein, contributes to the desired properties. In an aspect, the specific particle sizes of the SDD and the particular compositions as described provide the desired properties. In an aspect, compositions disclosed herein provide desirable pharmacokinetic performances and deliver an effective amount of active GLP1RA to the targeted portion of the gastrointestinal tract. In an aspect, disclosed herein is an elegant dosage form that is convenient for patients to take without the limitation of food or water restrictions.

Solid oral formulations provided herein can be useful for patients in need of treatment for T2D. Solid oral formulations provided herein can be useful for patients in need of chronic weight management.

Pharmaceutical compositions using amorphous forms of an active, have been prepared using spray dried dispersions (SDD), to develop dosage forms for poorly soluble drugs. However, this SDD approach is complicated by the presence of polymeric functional excipients that may be required to maintain the drug in an amorphous state. Compositions providing acceptable pharmacokinetic performance and desired food effects profile can be especially challenging for molecules possessing strong pH dependent solubility profiles. GLP1RA and GLPIRA-Ca exhibit such pH dependent solubility profile. Weak acids can present challenges in ensuring dissolution of the active substance is achieved in the desired portion of the gastrointestinal tract, particularly the stomach, where low pH could retard dissolution of weakly acidic drugs. Certain excipients may become unstable when added to a tablet composition described herein. In an embodiment, an excipient is stable in a tablet composition with pH modifier.

As used herein, a pH modifier means an inorganic basic salt including, but not limited to, calcium carbonate, magnesium carbonate, sodium bicarbonate, sodium carbonate, magnesium hydroxide, calcium hydroxide, magnesium oxide including both anhydrous and hydrated forms of the respective salts capable of raising the micro pH during tablet disintegration and dissolution.

In an embodiment, a GLP1RA or a pharmaceutically acceptable salt composition comprises a pH modifier that is sodium carbonate. In an embodiment, a GLP1RA or a pharmaceutically acceptable salt composition comprises a pH modifier that is sodium carbonate in its anhydrous form.

In an embodiment is a composition comprising GLP1RA, or a pharmaceutically acceptable salt thereof, and a pH modifier that is selected from the group consisting of calcium carbonate, sodium bicarbonate, sodium carbonate, magnesium hydroxide, and a mixture thereof. In an embodiment is a composition comprising GLP1RA, or a pharmaceutically acceptable salt thereof, and a pH modifier selected from the group consisting of calcium carbonate, anhydrous calcium carbonate, sodium bicarbonate, anhydrous sodium bicarbonate, sodium carbonate, anhydrous sodium carbonate, magnesium hydroxide, and anhydrous magnesium hydroxide.

In an embodiment, a tablet composition comprising GLP1RA or a pharmaceutically acceptable salt thereof, and a pH modifier is uncoated.

In an embodiment, a tablet composition is prepared as an immediate release (IR) dosage form that releases GLP1RA or a pharmaceutically acceptable salt thereof in the gastric compartment. Excessive amounts of pH modifier in the tablet may affect absorption of a co-administered medicine whose absorption is pH sensitive. In an embodiment, a pH modifier is in sufficiently low amounts such that it will not raise the bulk gastric pH during dissolution but sufficient to facilitate the dissolution of the GLP1RA or a pharmaceutically acceptable salt thereof. An immediate release dosage form with sufficiently low amount of a pH modifier may be desired to minimize potential for elevated stomach pH and drug-drug interaction (DDI) with a co-administered drug.

In an embodiment, a tablet composition comprising GLP1RA or a pharmaceutically acceptable salt thereof, and a pH modifier is coated with an immediate release coating.

As used herein, the term “immediate release coating” means a coating that is intended primarily for aesthetics and is not intended to alter disintegration and/or dissolution of the tablet. As used herein, appropriate immediate release coatings may be selected from known coatings, for example, but not limited to, Opadry® Clear (03K19229) (Colorcon Inc). As is common for moisture sensitive SDD based formulations, protection from moisture may be desired, to ensure product functionality and elegance throughout shelf life. This protection may be achieved through packaging, as well as utilization of coating materials to minimize moisture uptake of the tablet. One known immediate release coating with this functionality is Opadry® ambll (Colorcon).

In an embodiment is a composition comprising GLP1RA, or a pharmaceutically acceptable salt thereof; a pH modifier; and an immediate release coating.

In an embodiment, a tablet composition comprising GLP1RA, or a pharmaceutical salt thereof, and a pH modifier is prepared as a delayed release (DR) dosage form further comprising an enteric coating. A composition further comprising an enteric coating may release in the intestine at a pH of 5.5 or greater. Release in the intestine may be desired for GLP1RA, or a pharmaceutical salt thereof, to limit risks potentially associated with the presence of a pH modifier in the tablet. A DR composition may minimize potential food effect, and may have other favorable effects to the pharmacokinetic profile, for example, but not limited to, overall exposure and modulation of Cmax.

As used herein, “enteric coating” means a functional coating that is intended to prevent tablet disintegration and/or dissolution in the gastric environment but dissolve in the intestinal environment.

Once the solution is prepared, the solution is pumped to a spray dryer where the solution atomizes upon entry. Heated drying gas enters co-current to the atomized liquid at the top of the spray drying chamber at an approximate ratio of 0.044 kg/kg of spray solution to drying gas. The inlet temperature is adjusted to provide an outlet temperature of 35 to 45 °C. The solids formed in the spray dryer are collected from a cyclone as well as a filter housing on the gas stream. The gas is passed over a condenser maintained at -3 °C to remove (to a dewpoint of -3 °C) solvent. The gas is then heated to the inlet temperature and passed back to the spray dryer.

Particle Size Measurement

Particle size of the SDD was determined by laser diffraction utilizing wet dispersion on the Malvern Mastersizer 3000 equipped with the Hydro MV (medium volume) liquid disperser (Malvern Instruments Ltd. UK.). Optical model: Mie model, obscuration limits: 5-30%, general purpose model. The volume-based distribution was measured and the (DIO, D50, D90) quantiles were reported.

The SDDs of Preparations 2 and 3 have a mean particle size of about 40 to about 65 pm, or more specifically, about 40 to about 50 pm, in diameter, as measured by the above method.

Solubility Studies

Twenty -four Hour Aqueous Solubility of Crystalline GLPIRA-Ca at 25 °C

Table 15

*Not Measured

An embodiment of the present invention is an oral tablet formulation comprising an amorphous SDD of GLPIRA-Ca. GLPIRA-Ca in its crystalline form has poor aqueous solubility as shown in Table 15. An amorphous SDD of GLPIRA-Ca using PVP-VA as the carrier polymer has been shown to provide improved hydrophilicity and solubility as compared to the crystalline GLPIRA-Ca (Table 16). Twenty -four Hour Aqueous Solubility of Preparation 3 SDD at 25 °C

Table 16

Twenty-four-hour Aqueous Solubility of the Preparation 3, SDD at 37 °C

Table 17

As seen in Tables 16 and 17, Preparation 3 has pH dependent solubility. With a pKa of 5.1, it is expected that solubility of the drug would begin to increase at pH values near the pKa and dissolution performance will improve at pH values at or above the pKa. To test this, capsules containing the SDD and sufficient amounts of sodium bicarbonate to raise the pH of an acidic dissolution media to around the pKa were evaluated in dissolution experiments compared to a tablet containing much less pH modifier. The quantitative formulations are shown in Table 11 for the tablet and Table 3 for the capsule.

Dosage Dissolution Studies

Dosage forms are evaluated in a 2-stage dissolution test consisting of an acid stage (500 mL 0.0133N HC1/ 8.12 mM NaCl) for 1 hour followed by the addition of concentrated FaSSIF (400 mL) to convert media to the same pH and composition of conventional fasted state intestinal fluid. To prepare concentrated FaSSiF for each 1 L, sodium phosphate dibasic anhydrous (5.714 g), sodium phosphate monobasic anhydrous (2.906 g), and NaCl (12.354 g) are added together with water to make 1 L and mixed well. The pH should be about 7.0. Add SIF powder (5.6 g) (FaSSIF/FeSSIF/FaSSGF powder (Biorelevant)).

The test is run at 100 rpm using a USP II dissolution apparatus. Aliquots are withdrawn, filtered through a 0.22 micron filter, diluted 1 : 1 with MeOH to prevent drug precipitation and analyzed by HPLC.

It was surprisingly found that the IR tablet performed better in the gastric stage than the capsule formulation, despite the capsule formulation raising the pH in the media to above 5 due to the large amount of sodium bicarbonate and the tablet having no effect on the media pH, which remained at a pH of 2.

Dissolution Comparisons of Example 10 Tablet and Preparation 4 Capsule.

StDev refers to standard deviation.

Capsule Preparation 4 and IR tablet composition Example 7 are also compared using alternate dissolution conditions. Conditions used are USP II paddle at 100 rpm with 50 mM pH 6.8 phosphate buffer with 2% sodium lauryl sulfate as the dissolution media. Samples are analyzed by HPLC.

Surprisingly, despite having a significant amount of sodium bicarbonate present that should facilitate dissolution of the SDD from the capsule, the IR tablet again released more rapidly than the capsule with 100% release achieved within 30 minutes, while the capsule only achieved 35% release at 30 minutes and did not achieve >90% release until about 75 minutes.

Preparation 4 Capsule Alternate Dissolution Conditions

Composition Example 7 Alternate Dissolution Conditions

Table 20

The pH modifiers in both the IR and DR tablets facilitate dissolution of the weakly acidic drug by raising the local, or micro, pH of the tablet as it disintegrates. Enteric tablets are used to discover levels of pH modifier required for enteric tablet compositions. Enteric Coated Tablets, Example 9, are tested in a 2-stage dissolution test using a USP II apparatus with paddle speed of 100 rpm. An acid challenge stage is conducted first lasting 2 hours in pH 4.5 sodium acetate buffer (500 mL) after which the tablets are removed and placed into FaSSiF (Biorelevant) (500 mL). Aliquots are withdrawn, filtered through a 0.22 micron filter, diluted 1 : 1 with MeOH to prevent drug precipitation and analyzed by HPLC.

Unexpectedly, very high levels of pH modifier (20 wt% in the tablet) resulted in poorer dissolution behavior of the DR tablets compared to lower levels. Further, an optimal level of peak and more sustained dissolution is achieved at around 10 wt% sodium carbonate.

Dissolution Studies for Delayed Release Tablet Table 21 nm = not measurec

Tablets of Example 11 and Example 12 are tested in a 2-stage dissolution test using a USP II: apparatus with paddle speed of 100 rpm. The acid challenge stage is 2 hours in pH 4.5 sodium acetate buffer (500 mL) after which the tablets are removed and placed into FaSSiF (Biorelevant) (500 mL). Aliquots are withdrawn, filtered through a 0.22 micron filter, diluted 1 : 1 with MeOH to prevent drug precipitation and analyzed by HPLC.

It was surprisingly found that croscarmellose sodium as used in Example 11 is not able to afford the desired release profile whereas crospovidone as used in Example 12 affords the desired release profile.

Two Stage Dissolution Testing of Tablets

Table 22

In a further embodiment, the rate of release from the enterically coated tablets may be controlled to affect specific aspects of the PK profile, such as Cmax or the peak to trough plasma concentrations as these may be beneficial to the patient to help with tolerability and/or efficacy.

Controlled release from tablets is often achieved using rate controlling polymers such as hypromellose as in hydrophilic sustained release matrix tablets. The challenge with hypromellose or similar polymers is that they tend to work over several hours through diffusional and/or erosional mechanisms. This time span may be too long for low permeability molecules, where not maximizing drug concentration in the intestinal lumen, if the drug is released gradually over many hours, may result in decreased flux across the intestinal epithelium and subsequently lower absorption.

It was surprising found that controlling the amount of super disintegrant in the enterically coated dosage forms enables a significant degree of control of the rate of release over the desired time of complete release within 30 minutes

Tablets T1 and T2 are evaluated in a 2-stage dissolution test substantially similar to what has already been described, except the pH 4.5 sodium acetate acid stage is set to 1 hour followed by transfer of the tablet to FaSSiF (Biorelevant). The results are shown in Table 23.

Surprisingly, simply modulating the disintegrant levels can achieve a controlled level of release in the FaSSiF.

Two stage Dissolution Study of Tablets T1 and T2 at pH 4.5

Table 23

Another lever to modulate the release of the drug from the enteric tablets is to alter the amount of sodium carbonate. The tablets are subjected to dissolution in pH 6.8 phosphate buffer with 2% sodium lauryl sulfate as described herein. Results of this study demonstrate that there is a synergy between the level of disintegrant and the amount of pH modifier that can be used to control release of drug from the tablet. Further, the release is controlled to within the desired range of within 30 minutes to not more than 3 hours to model the approximate in-vivo transit time through the small intestine where most drug absorption is expected to occur. The results are shown in Table 24.

Dissolution Time Study of Composition Tablets, Tl, T2, A, B, C, D at pH 6.8

Table 24

Clinical Trial A multiple-ascending dose study was conducted to characterize and compare the pharmacokinetics (PK) of prototype formulations of Preparation 4 (capsule), Example 1 (DR Tablet composition Tl with enteric coating prepared as in Example 9, referred to below as Tl DR Tablet), and Example 7 (IR Tablet Composition E with immediate release coating, referred to below as E IR Tablet). The study was conducted in two parts: A and B.

Part A evaluated the safety, tolerability, and PK of multiple oral doses of GLP1RA formulation prototypes T1 and E in healthy participants versus the reference capsule Preparation 4. A dose titration period was from Day 1 through Day 18, where participants received increasing doses of GLP1RA in a capsule for dose titration. Within- treatment dose escalation was every 6 days and reached a maximum dose of 16 mg of GLP1RA once daily (QD) on Day 19. On Days 19 to 24, participants received reference capsule Preparation 4 (16 mg QD) before entering the test phase, from Days 25 to 36. During test period-1, the participants were administered GLP1RA a prototype tablet (16 mg QD) formulations as per their randomization. The participants were then crossed over on Day 31 for period-2 and received the second prototype tablet (16 mg QD) through Day 36.

Cmax = maximum observed concentration; Frei AUC(0-24) = relative bioavailability based on AUC(0-24); Frei Cmax = relative bioavailability based on Cmax; h = hour; N/A = not applicable

The results of Part A indicate that the average peak and overall exposure levels (as measured by Cmax and AUC(0-24)) for 16 mg, DR Tablet T1 were approximately 67% and 50% higher, respectively, than those for 16 mg reference Preparation 4 capsule. These increases were statistically significant at the 10% significance level (p< 001 for both Cmax and AUC(0-24)).

Similarly, for 16 mg Tablet E IR tablet, the average peak and overall exposure levels (as measured by Cmax and AUC(0-24)) were approximately 47% and 41% higher, respectively, than those for 16 mg reference capsule. These increases were statistically significant at the 10% significance level (p=.007 and p< 001 for Cmax and AUC(0-24), respectively).

Part B further evaluated Tablet E IR tablet regarding food effect and DDI effect with a co-administered proton pump inhibitor (PPI). As in Part A, treatment escalation occurred every 6 days during a titration period and reached a maximum dose of 16 mg QD on Day 19. Treatment then proceeded with GLP1RA in a fasted or fed state and a fasted state with a co-administered PPI. Each option began with a 6-day reference period (16 mg QD) using Tablet E IR tablet as the reference, followed by two 6-day test periods (16 mg QD).

Cmax = maximum observed concentration; Frei AUC(0-24) = relative bioavailability based on AUC(0-24); Frei Cmax = relative bioavailability based on Cmax; h = hour; N/A = not applicable

The results of Part B indicate that the average peak and overall exposure levels (as measured by Cmax and AUC(0-24)) for 16 mg Tablet E IR tablet fed were comparable (that is, fed exposure within 11% and 4% of fasted exposure for Cmax and AUC(0-24), respectively) to those for 16 mg Tablet E IR tablet fasted (p=.39 and p=.66 for Cmax and AUC(0-24), respectively).

For 16 mg Tablet E IR tablet with PPI, the average peak and overall exposure levels (as measured by Cmax and AUC(0-24)) were also comparable (that is, 6% lower and 6% higher for Cmax and AUC(0-24), respectively) to those for 16 mg IR Tablet Composition E (p=.65 and p=.57 for Cmax and AUC(0-24), respectively).
