Application Number:16/951,796
Patent Claims: 1. A pharmaceutical composition comprising a crystalline form of ibrutinib and a pharmaceutically acceptable excipient, wherein said crystalline form of ibrutinib is produced by a process, comprising combining a solvent solution comprising alcohol with a crystalline ibrutinib having 2-theta peaks at 7.0.+-.0.1.degree., 14.0.+-.0.1.degree., 15.7.+-.0.1.degree., and 18.2.+-.0.1.degree.; and a pharmaceutically acceptable excipient.

2. The pharmaceutical composition of claim 1, wherein the alcohol is selected from the group consisting of: methanol and ethanol.

3. The pharmaceutical composition of claim 1, wherein the alcohol is ethanol.

4. The pharmaceutical composition of claim 1, wherein the alcohol is methanol.

5. The pharmaceutical composition of claim 3, wherein the crystalline form of ibrutinib has 2-theta peaks at 5.7.+-.0.1.degree., 13.6.+-.0.1.degree., 16.1.+-.0.1.degree., 18.9.+-.0.1.degree., and 21.3.+-.0.1.degree..

6. The pharmaceutical composition of claim 3, wherein the solvent solution further comprises water.

7. The pharmaceutical composition of claim 6, wherein the crystalline form of ibrutinib has 2-theta peaks at 5.2.+-.0.1.degree., 10.2.+-.0.1.degree., 16.5.+-.0.1.degree., 18.5.+-.0.1.degree., and 20.8.+-.0.1.degree..

8. The pharmaceutical composition of claim 1, wherein the crystalline form of ibrutinib is recovered from the solvent solution.

9. The pharmaceutical composition of claim 2, wherein the crystalline form of ibrutinib is recovered from the solvent solution.

10. The pharmaceutical composition of claim 3, wherein the crystalline form of ibrutinib is recovered from the solvent solution.

11. The pharmaceutical composition of claim 4, wherein the crystalline form of ibrutinib is recovered from the solvent solution.

12. The pharmaceutical composition of claim 5, wherein the crystalline form of ibrutinib is recovered from the solvent solution.

13. The pharmaceutical composition of claim 6, wherein the crystalline form of ibrutinib is recovered from the solvent solution.

14. The pharmaceutical composition of claim 7, wherein the crystalline form of ibrutinib is recovered from the solvent solution.
