Abstract

Described herein is the Bruton's tyrosine kinase (Btk) inhibitor 1-((R)-3-(4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)piperidin-1-yl)prop-2-en-1-one, including crystalline forms, solvates and pharmaceutically acceptable salts thereof. Also disclosed are pharmaceutical compositions that include the Btk inhibitor, as well as methods of using the Btk inhibitor, alone or in combination with other therapeutic agents, for the treatment of autoimmune diseases or conditions, heteroimmune diseases or conditions, cancer, including lymphoma, and inflammatory diseases or conditions.

First claim

What is claimed is:

1. A crystalline form of 1-((R)-3-(4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)piperidin-1-yl)prop-2-en-1-one that has a differential scanning calorimetry (DSC) thermogram having an endotherm with a peak at about 137° C. to about 139° C.

2. The crystalline form of claim 1 , wherein the endotherm has an onset at about 134° C. to about 135° C.

3. The crystalline form of claim 1 , wherein the crystalline form is unsolvated.

4. The crystalline form of claim 2 , wherein the crystalline form is unsolvated.

5. The crystalline form of claim 1 , wherein the crystalline form has a thermo-gravimetric analysis (TGA) thermogram substantially similar to the one set forth in FIG. 11 .

6. The crystalline form of claim 2 , wherein the crystalline form has a TGA thermogram substantially similar to the one set forth in FIG. 11 .

7. The crystalline form of claim 3 , wherein the crystalline form has a TGA thermogram substantially similar to the one set forth in FIG. 11 .

8. The crystalline form of claim 4 , wherein the crystalline form has a TGA thermogram substantially similar to the one set forth in FIG. 11 .

9. The crystalline form of claim 1 , wherein the DSC thermogram was generated by heating the crystalline form at a rate of 10° C./min.

10. The crystalline form of claim 5 , wherein the DSC thermogram was generated by heating the crystalline form at a rate of 10° C./min.

11. A pharmaceutical formulation comprising the crystalline form of claim 1 and at least one pharmaceutically acceptable ingredient.

12. The pharmaceutical formulation of claim 11 , wherein the crystalline form is unsolvated.

13. The pharmaceutical formulation of claim 12 , wherein the crystalline form has a thermo-gravimetric analysis (TGA) thermogram substantially similar to the one set forth in FIG. 11 .

14. The pharmaceutical formulation of claim 11 , wherein the crystalline form has the DSC thermogram generated by heating the crystalline form at a rate of 10° C./min.

15. A crystalline form of 1-((R)-3-(4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)piperidin-1-yl)prop-2-en-1-one that has an X-ray powder diffraction (XRPD) pattern comprising a 2-Theta peak at about 7.0°.

16. The crystalline form of claim 15 , wherein the XRPD pattern further comprises a 2-Theta peak at about 14.0°.

17. The crystalline form of claim 15 , wherein the XRPD pattern further comprises a 2-Theta peak at about 18.2°.

18. The crystalline form of claim 15 , wherein the crystalline form is unsolvated.

19. The crystalline form of claim 16 , wherein the crystalline form is unsolvated.

20. The crystalline form of claim 17 , wherein the crystalline form is unsolvated.

21. A pharmaceutical formulation comprising the crystalline form of claim 15 and at least one pharmaceutically acceptable ingredient.

22. The pharmaceutical formulation of claim 21 , wherein the crystalline form is unsolvated.
