Patent Application

The present specification relates to a pharmaceutical formulation comprising 1-{2-[(1R)-1-aminoethyl]-4-chlorobenzyl}-2-thioxo-1,2,3,5-tetrahydro-4H-pyrrolo[3,2-d]pyrimidin-4-one (Compound 1). The specification also relates to the use of the formulation in therapy, particularly the treatment of heart failure with preserved ejection fraction (HFpEF) and chronic obstructive pulmonary disease (COPD), as well as methods of treatment involving the administration of the formulation.
Compound 1 is very adhesive and easily agglomerates into large (0.5-1 mm) particles. A suitable formulation must have good manufacturability (the extent to which a product can be manufactured with relative ease at minimum cost and maximum reliability) because a robust process is needed to deliver product for late-stage clinical trials and commercial purposes. Where the formulation is a tablet, the tablets must achieve a suitable tensile strength, without the need for the application of a high compression force, whilst maintaining an acceptable tablet porosity. These factors minimise the risk of over-compression and variable dissolution rates—a suitable formulation must release its active ingredient in a uniform and acceptable manner. Finally, a formulation for human use must employ pharmaceutically acceptable excipients that meet regulatory requirements for chronic dosing, and must be stable for a meaningful period of time, typically >1 year and ideally up to 3 years.
The present specification describes a pharmaceutical formulation of Compound 1 that satisfies these criteria and is suitable for manufacture on a commercial scale.
Many embodiments are detailed throughout the specification and will be apparent to a reader skilled in the art. The specification is not to be interpreted as being limited to any of the recited embodiments.

Compound 1 was produced by the synthesis route disclosed in WO2016/087338. The excipients used in the Example and Results sections are shown in Table 2.
Tablets of Compound 1 as described herein were manufactured using a dry process with direct compression.
The formulations described in Tables 3-A and 3-B were prepared according (or analogous) to the procedure described below at a 1 kg scale and summarized in
Compression Profile
All batches were compressed separately using a suitable rotary tablet press (e.g. Korsch XL 100) with the same punch design (round 6 mm for 2.5 mg strength; round 8 mm for 5 mg strength and oval 14 mm×7 mm for 10 mg strength) under different compression forces. Breaking force and thickness of the produced tablets were characterized using suitable hardness and thickness measurement equipment. Tensile strength was calculated in terms of breaking force and dimension of produce tablets. The results are presented in
The compression profile depicts the tablet tensile strength as a function of the applied compaction force for all batches. This profile is normalised for the punch tip face area and tablet geometry, allowing for a true comparison of formulation robustness independent of tablet size.
Dissolution Profiles
The dissolution profiles of the tablets were performed in accordance with the United States Pharmacopeia and the European Pharmacopoeia, using Apparatus II (paddle apparatus) with a stirring speed of 75 rpm in a pH 6.1 sodium phosphate (0.075 μM)/citric acid (0.025 μM) buffer. Concentration of Compound 1 is quantified by comparison of the UV response at 290 nm with a background correction at 400 nm of the dissolution sample with that of an external reference standard solution.
Dissolution profiles of the tablets were measured in pH6.1 USP medium with method 2.
Tablets with the Variant 15 formulation comprising 2.5 mg of Compound 1 and 5 mg of Compound 1 were film-coated using standard pan coating techniques as shown in
Tablets comprising 2.5 mg Compound 1(100 mg total weight, herein after “2.5 mg core tablets”) and 5 mg Compound 1 (200 mg total weight, herein after “5 mg core tablets”) having the composition of described in Table 4 were prepared according to Example 1.
The 5 mg core tablets were film-coated using standard pan coating techniques as shown in
Dissolution profiles of the tablets were measured in pH 6.1 USP medium with method 2 as described in Example 2.
The 2.5 mg core tablets were coated with Opadry 03K630008-CN Orange for a weight gain of 3.3% and the 5 mg core tablets were coated with Opadry 03K630008-CN Orange for a weight gain of 2.8%. Dissolution profiles of the tablets were measured in pH 6.1 USP medium with method 2 as described in Example 2 and the results are shown in
