Sunitinib Malate

Sunitinib malate was first approved by the U.S. Food and Drug Administration (FDA) on Jan 26, 2006, then approved by European Medicine Agency (EMA) on July 19, 2006, and approved by Pharmaceuticals and Medical Devices Agency of Japan (PMDA) on Apr 16, 2008. It was developed and marketed as Sutent® by Pfizer.

Sunitinib is a small molecule that inhibits multiple receptor tyrosine kinases (RTKs), some of which are implicated in tumor growth, pathologic angiogenesis, and metastatic progression of cancer. It is indicated for the treatment of gastrointestinal stromal tumor (GIST), advanced renal cell carcinoma (RCC), and pancreatic neuroendocrine tumors (pNET).

Sutent® is available as capsule for oral use, containing 12.5, 25, 37.5 or 50 mg of free Sunitinib. The recommended dose is 50 mg once daily with or without food for GIST and RCC in 4 weeks on treatment, followed by 2 weeks off. Another dose is 37.5 mg once daily with or without food for pNET, continuously without a scheduled off-treatment period.
