Sutent (sunitinib malate) is a prescription drug used to treat certain types of cancer. The drug comes as an oral capsule that’s usually taken once per day.
Specifically, Sutent is used in adults:
- to treat gastrointestinal stromal tumors (GIST). It’s used after treatment with imatinib (Gleevac) if you are not able to tolerate imatinib or your condition worsens after taking it.
- to treat advanced renal cell carcinoma (RCC) This is a type of kidney cancer that has spread outside the kidneys.
- as an adjuvant treatment of RCC in people at high risk of kidney cancer returning after nephrectomy (surgery to remove localized kidney cancer). Adjuvant means it’s an extra treatment after your first cancer treatment, used to lower your risk of the cancer from returning.
- to treat progressive pancreatic neuroendocrine tumors (PNET). For this use, Sutent is used for PNET that:
- cannot be removed by surgery
- is locally advanced (near the pancreas) or metastatic (spread to other areas of the body)
- is well differentiated (meaning the cells are slow growing and resemble natural cells)
The active ingredient in Sutent is sunitinib malate. Sutent belongs to a group of drugs called kinase inhibitors.

Your doctor will closely monitor your liver function while you’re taking Sutent. They may adjust your dose or pause or stop your treatment if you experience liver problems with this medication.
Heart problems: If you have or have had heart problems, including irregular heart rhythm, your doctor may decrease your dosage of Sutent to help prevent an arrhythmia.

If you miss a dose of Sutent and it’s been less than 12 hours, take it as soon as you remember. But if it’s been longer than 12 hours, skip the missed dose and take your next dose at its usual time. If you’re not sure whether you should take a missed dose, talk with your doctor or pharmacist.
