Svitinib Capsule

Sunitinib is a kinase inhibitor indicated for: treatment of adult patients with gastrointestinal stromal tumor (GIST) after disease progression on or intolerance to imatinib mesylate. treatment of adult patients with advanced renal cell carcinoma (RCC). adjuvant treatment of adult patients at high risk of recurrent RCC following nephrectomy. treatment of progressive, well-differentiated pancreatic neuroendocrine tumors (pNET) in adult patients with unresectable locally advanced or metastatic disease. Gastrointestinal Stromal Tumor Sunitinib capsules are indicated for the treatment of adult patients with gastrointestinal stromal tumor (GIST) after disease progression on or intolerance to imatinib mesylate. Advanced Renal Cell Carcinoma Sunitinib capsules are indicated for the treatment of adult patients with advanced renal cell carcinoma (RCC). Adjuvant Treatment of Renal Cell Carcinoma Sunitinib capsules are indicated for the adjuvant treatment of adult patients at high risk of recurrent RCC following nephrectomy. Advanced Pancreatic Neuroendocrine Tumors Sunitinib capsules are indicated for the treatment of progressive, well-differentiated pancreatic neuroendocrine tumors (pNET) in adult patients with unresectable locally advanced or metastatic disease.

Boxed warning. HEPATOTOXICITY Hepatotoxicity may be severe, and in some cases, fatal. Monitor hepatic function and interrupt, dose reduce, or discontinue Sunitinib capsules as recommended. WARNING: HEPATOTOXICITY See full prescribing information for complete boxed warning. Hepatotoxicity may be severe, and in some cases fatal. Hepatotoxicity: Fatal liver failure has been observed. Monitor liver function tests at baseline, during each cycle, and as clinically indicated. Interrupt Sunitinib for Grade 3 hepatotoxicity until resolution to Grade ≤1 or baseline and resume Sunitinib at a reduced dose; discontinue if no resolution. Discontinue Sunitinib in patients with Grade 4 hepatoxicity, in patients who have subsequent severe changes in liver function tests or other signs and symptoms of liver failure. Cardiovascular Events: Myocardial ischemia, myocardial infarction, heart failure, cardiomyopathy, and decreased left ventricular ejection fraction (LVEF) to below the lower limit of normal including death have occurred. Monitor for signs and symptoms of congestive heart failure and consider monitoring LVEF at baseline and periodically during treatment. Discontinue Sunitinib for clinical manifestations of congestive heart failure. Interrupt and/or dose reduce for decreased LVEF. QT Interval Prolongation and Torsade de Pointes: Monitor patients at higher risk for developing QT interval prolongation. Consider monitoring of electrocardiograms and electrolytes. Hypertension: Monitor blood pressure at baseline and as clinically indicated. Initiate and/or adjust antihypertensive therapy as appropriate. Interrupt Sunitinib for Grade 3 hypertension until resolution to Grade ≤1 or baseline, then resume Sunitinib at a reduced dose. Discontinue Sunitinib in patients who develop Grade 4 hypertension. Hemorrhagic Events: Tumor-related hemorrhage and viscus perforation (both with fatal events) have occurred. Perform serial complete blood counts and physical examinations. Interrupt Sunitinib for Grade 3 or 4 hemorrhagic events until resolution to Grade ≤1 or baseline, then resume at a reduced dose; discontinue if no resolution. Tumor Lysis Syndrome (TLS): TLS (some fatal) has been reported primarily in patients with RCC and GIST. Monitor these patients and treat as clinically indicated. Thrombotic microangiopathy (TMA): TMA, including thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, sometimes leading to renal failure or a fatal outcome, has been reported. Discontinue Sunitinib for TMA. Proteinuria: Renal failure or a fatal outcome has occurred. Monitor urine protein. Interrupt treatment for 24-hour urine protein of 3 or more grams.

The following clinically significant adverse reactions are described elsewhere in the labeling. Hepatotoxicity Cardiovascular Events QT Interval Prolongation and Torsade de Pointes Hypertension Hemorrhagic Events Tumor Lysis Syndrome Thrombotic Microangiopathy Proteinuria Dermatologic Toxicities Reversible Posterior Leukoencephalopathy Syndrome Thyroid Dysfunction Hypoglycemia Osteonecrosis of the Jaw Impaired Wound Healing The most common adverse reactions (≥25%) are fatigue/asthenia, diarrhea, mucositis/stomatitis, nausea, decreased appetite/anorexia, vomiting, abdominal pain, hand-foot syndrome, hypertension, bleeding events, dysgeusia/altered taste, dyspepsia, and thrombocytopenia. Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The pooled safety population described in the Warnings and Precautions reflect exposure to Sunitinib in 7,527 patients with GIST, RCC (advanced and adjuvant), or pNET. In this pooled safety population, the most common adverse reactions (≥25%) were fatigue/asthenia, diarrhea, mucositis/stomatitis, nausea, decreased appetite/anorexia, vomiting, abdominal pain, hand-foot syndrome, hypertension, bleeding events, dysgeusia/altered taste, dyspepsia, and thrombocytopenia. Gastrointestinal Stromal Tumor The safety of Sunitinib was evaluated in Study 1, a randomized, double-blind, placebo-controlled trial in which previously treated patients with GIST received Sunitinib 50 mg daily on Schedule 4/2 (n = 202) or placebo (n = 102). Median duration of blinded study treatment was 2 cycles for patients on Sunitinib (mean: 3.0; range: 1 to 9) and 1 cycle (mean; 1.8; range: 1 to 6) for patients on placebo at the time of the interim analysis. Permanent discontinuation due to an adverse reaction occurred in 7% of patients in the Sunitinib arm. Dose reductions occurred in 11% and dose interruptions occurred in 29% of patients who received Sunitinib. Table 3 summarizes the adverse reactions for Study 1. Table 3.
