Azetidinyl phenyl, pyridyl or pyrazinyl carboxamide derivatives as JAK inhibitors
The present invention provides azetidinyl phenyl, pyridyl, or pyrazinyl carboxamide derivatives, as well as their compositions and methods of use, that modulate the activity of Janus kinase (JAKs) and are useful in the treatment of diseases related to the activity of JAK including, for example, inflammatory disorders, autoimmune disorders, cancer, and other diseases.
1. A method of inhibiting or ameliorating a disorder selected from myelofibrosis, polycythemia vera (PV), essential thrombocythemia (ET), multiple myeloma, pancreatic cancer, breast cancer, lung cancer, colorectal cancer, rheumatoid arthritis, lymphoma, leukemia, cachexia, Castleman's disease, graft versus host disease and allograft rejection in a patient in need thereof, comprising administering to said patient a therapeutically effective amount of a compound, which is 5-{3-(Cyanomethyl)-3-[4-(1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}-N-isopropylpyrazine-2-carboxamide, or a pharmaceutically acceptable salt thereof.
2. The method of claim 1 , wherein the disorder is myelofibrosis.
3. The method of claim 1 , wherein the disorder is polycythemia vera (PV).

17. The method of claim 14 , wherein the leukemia is chronic myelogenous leukemia (CML).
18. The method of claim 14 , wherein the leukemia is chronic myelomonocytic leukemia (CMML).
19. The method of claim 1 , wherein the disorder is cachexia.
20. The method of claim 19 , wherein the cachexia results from or is associated with cancer.
21. The method of claim 1 , wherein the disorder is Castleman's disease.
