6.1 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 malate in 7527 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 malate was evaluated in Study 1, a randomized, double-blind, placebo-controlled trial in which previously treated patients with GIST received sunitinib malate 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 malate (mean: 3.0; range: 1-9) and 1 cycle (mean; 1.8; range: 1-6) 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 malate arm.
Dose reductions occurred in 11% and dose interruptions occurred in 29% of patients who received sunitinib malate.

Long-Term Safety in RCC The long-term safety of sunitinib malate in patients with metastatic RCC was analyzed across 9 completed clinical studies conducted in the first-line, bevacizumab-refractory, and cytokine-refractory treatment settings.The analysis included 5739 patients, of whom 807 (14%) were treated for at least 2 years and 365 (6%) for at least 3 years.
Prolonged treatment with sunitinib malate did not appear to be associated with new types of adverse reactions.There appeared to be no increase in the yearly incidence of adverse reactions at later time points.
Hypothyroidism increased during the second year of treatment with new cases reported up to year 4.
Adjuvant Treatment of RCC The safety of sunitinib malate was evaluated in S-TRAC, a randomized, double-blind, placebo-controlled trial in which patients who had undergone nephrectomy for RCC received sunitinib malate 50 mg daily on Schedule 4/2 (n=306) or placebo (n=304).The median duration of treatment was 12.4 months (range: 0.13 to 14.9) for sunitinib malate and 12.4 months (range: 0.03 to 13.7) for placebo.
Permanent discontinuation due to an adverse reaction occurred in 28% of patients in the sunitinib malate arm.
Adverse reactions leading to permanent discontinuation in >2% of patients include hand-foot syndrome and fatigue/asthenia.
Dosing interruptions occurred in 54% and dose reductions occurred in 46% of patients who received sunitinib malate.

a Grade 4 laboratory abnormalities in patients on sunitinib malate included alkaline phosphatase (1%), lipase (2%), creatinine (1%), potassium decreased (1%), neutrophils (2%), hemoglobin (2%), and platelets (1%).
b Grade 4 laboratory abnormalities in patients on placebo included amylase (1%), lipase (1%), and hemoglobin (2%).
After an interim analysis, the study was unblinded and patients on the placebo arm were given the opportunity to receive open-label sunitinib malate [ see Clinical Studies (14.1) ].
For 241 patients randomized to the sunitinib malate arm, including 139 who received sunitinib malate in both the double-blind and open-label phases, the median duration of sunitinib malate treatment was 6 cycles (mean: 8.5; range: 1–44).
For the 255 patients who ultimately received open-label sunitinib malate treatment, median duration of treatment was 6 cycles (mean: 7.8; range: 1–37) from the time of the unblinding.
Permanent discontinuation due to an adverse reaction occurred in 20% of patients who received sunitinib malate.
Dosage interruption occurred in 46% and dose reduction occurred in 28% of patients who received sunitinib malate.

Long-Term Safety in RCC The long-term safety of sunitinib malate in patients with metastatic RCC was analyzed across 9 completed clinical studies conducted in the first-line, bevacizumab-refractory, and cytokine-refractory treatment settings.The analysis included 5739 patients, of whom 807 (14%) were treated for at least 2 years and 365 (6%) for at least 3 years.
Prolonged treatment with sunitinib malate did not appear to be associated with new types of adverse reactions.There appeared to be no increase in the yearly incidence of adverse reactions at later time points.
Hypothyroidism increased during the second year of treatment with new cases reported up to year 4.
Adjuvant Treatment of RCC The safety of sunitinib malate was evaluated in S-TRAC, a randomized, double-blind, placebo-controlled trial in which patients who had undergone nephrectomy for RCC received sunitinib malate 50 mg daily on Schedule 4/2 (n=306) or placebo (n=304).The median duration of treatment was 12.4 months (range: 0.13 to 14.9) for sunitinib malate and 12.4 months (range: 0.03 to 13.7) for placebo.
Permanent discontinuation due to an adverse reaction occurred in 28% of patients in the sunitinib malate arm.
Adverse reactions leading to permanent discontinuation in >2% of patients include hand-foot syndrome and fatigue/asthenia.
Dosing interruptions occurred in 54% and dose reductions occurred in 46% of patients who received sunitinib malate.
