Processes for the preparation of (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]-pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide and solid state forms thereof
The present disclosure relates to processes for preparing (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide, solid state forms thereof, and corresponding pharmaceutical compositions, methods of treatment (including treatment of rheumatoid arthritis and various spondyloarthritic conditions, including types of axial spondyloarthritis (axSpA)), kits, methods of synthesis, and products-by-process. In various aspects, provided are methods for treating active non-radiographic axSpA (nr-axSpA) and methods for treating active ankylosing spondylitis (AS).
1. A method of treating a human patient having a spondyloarthropathy, comprising orally administering once daily to the patient a tablet comprising a therapeutically effective amount of (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide (Compound 1), wherein the therapeutically effective amount is 15 mg.
2. The method of claim 1 , wherein the patient is an adult patient.
3. The method of claim 1 , wherein the patient has had an inadequate response or intolerance to one or more non-steroidal anti-inflammatory drugs (NSAIDs).
4. The method of claim 1 , wherein the patient has had an inadequate response or intolerance to an anti-TNF biologic agent.
5. The method of claim 1 , wherein the spondyloarthropathy is ankylosing spondylitis.
6. The method of claim 1 , wherein the therapeutically effective amount of Compound 1 is administered as 15.4 mg of Freebase Hydrate Form C, wherein Freebase Hydrate Form C has an X-ray powder diffraction pattern characterized by peaks at 13.4±0.2, 15.1±0.2, 15.5±0.2, 17.0±0.2, 20.9±0.2, and 21.7±0.2 degrees two theta when measured at about 25° C. with monochromatic Kα1 radiation.
7. The method of claim 1 , wherein the method results in an Assessment of SpondyloArthritis International Society 20 (ASAS20) response at 14 weeks after the first daily administration.
8. The method of claim 7 , wherein the patient has had an inadequate response or intolerance to one or more non-steroidal anti-inflammatory drugs (NSAIDs).
9. The method of claim 7 , wherein the patient has had an inadequate response or intolerance to an anti-TNF biologic agent.
10. A method of treating a human patient having a spondyloarthropathy, comprising orally administering once daily to the patient a tablet comprising a therapeutically effective amount of (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide (Compound 1), wherein the therapeutically effective amount is 15 mg, and wherein the method results in an Assessment of SpondyloArthritis International Society 40 (ASAS40) response at 14 weeks after the first daily administration.
11. The method of claim 10 , wherein the patient is an adult patient.
12. The method of claim 10 , wherein the patient has had an inadequate response or intolerance to one or more non-steroidal anti-inflammatory drugs (NSAIDs).
13. The method of claim 10 , wherein the patient has had an inadequate response or intolerance to an anti-TNF biologic agent.
14. The method of claim 10 , wherein the spondyloarthropathy is ankylosing spondylitis.
15. The method of claim 10 , wherein the therapeutically effective amount of Compound 1 is administered as 15.4 mg of Freebase Hydrate Form C, wherein Freebase Hydrate Form C has an X-ray powder diffraction pattern characterized by peaks at 13.4±0.2, 15.1±0.2, 15.5±0.2, 17.0±0.2, 20.9±0.2, and 21.7±0.2 degrees two theta when measured at about 25° C. with monochromatic Kα1 radiation.
