Application Number:	US16/678,760
Patent Claims:	1. A method of treating one or more diseases mediated by kinase insert domain-containing receptor (KDR) in a subject in need thereof, comprising: administering to said subject an effective amount for treating the one or more disease of a pharmaceutical composition comprising a crystalline form of the compound of Formula A wherein the crystalline form of the compound of Formula A has an x-ray powder diffraction pattern when measured using a CuKα radiation comprising peaks expressed in degrees 2-theta (2θ) at 5.3±0.2, 10.7±0.2, 13.9±0.2, and 14.6±0.2; and a pharmaceutically acceptable carrier; wherein the content of other crystalline forms of the compound of Formula A in said pharmaceutical composition is less than 40% by weight. 2. The method according to claim 1, wherein the content of other crystalline forms of the compound of Formula A in said pharmaceutical composition is less than 30% by weight. 3. The method according to claim 1, wherein the content of other crystalline forms of the compound of Formula A in said pharmaceutical composition is less than 20% by weight. 4. The method according to claim 1, wherein the content of other crystalline forms of the compound of Formula A in said pharmaceutical composition is less than 10% by weight. 5. The method according to claim 1, wherein the content of other crystalline forms of the compound of Formula A in said pharmaceutical composition is less than 5% by weight. 6. The method according to claim 1, wherein the content of other crystalline forms of the compound of Formula A in said pharmaceutical composition is less than 1% by weight. 7. The method according to claim 1, wherein the one or more diseases is cancer. 8. The method according to claim 7, wherein the cancer is chosen from lung cancer, head and neck cancer, pancreatic cancer, colon cancer, breast cancer, ovarian cancer, prostate cancer, stomach cancer, kidney cancer, liver cancer, brain cancer, bone cancer, sarcoma, and leukemia. 9. The method according to claim 7, wherein the cancer is lung cancer. 10. The method according to claim 7, wherein the cancer is stomach cancer. 11. A method of treating one or more diseases mediated by kinase insert domain-containing receptor (KDR) in a subject in need thereof, comprising: administering to said subject an effective amount for treating the one or more disease of a pharmaceutical composition comprising a crystalline form of the compound of Formula A wherein the crystalline form of the compound of Formula A has an x-ray powder diffraction pattern when measured using a CuKα radiation comprising peaks expressed in degrees 2-theta (2θ) at 5.3±0.2, 10.7±0.2, 13.9±0.2, and 14.6±0.2; a pharmaceutically acceptable carrier; and one or more other therapeutically active compounds; wherein the content of other crystalline forms of the compound of Formula A in said pharmaceutical composition is less than 40% by weight.
