Application Number:12/095,114
Patent Claims: 1. A method of reversing or inhibiting the progress of abnormal cell growth in a mammal comprising, administering to said mammal a therapeutically effective amount of (R)-3-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-5-(1-piperidin-4-yl-1H-py- razol-4-yl)-pyridin-2-ylamine or a pharmaceutically acceptable salt thereof, wherein the abnormal cell growth is a cancer mediated by an anaplastic lymphoma kinase.

2. The method of claim 1, wherein the mammal is a human.

3. The method of claim 1, wherein the mammal is a dog.

4. The method of claim 1, wherein the anaplastic lymphoma kinase is a genetically altered anaplastic lymphoma kinase.

6. The method of claim 1, wherein (R)-3-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-5-(1-piperidin-4-yl-1H-py- razol-4-yl)-pyridin-2-ylamine or pharmaceutically acceptable salt thereof is administered as a pharmaceutical composition comprising (R)-3-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-5-(1-piperidin-4-yl-1H-py- razol-4-yl)-pyridin-2-ylamine or a pharmaceutically acceptable salt thereof and at least one pharmaceutically acceptable carrier.
