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 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 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.

After an interim analysis , the study was unblinded and patients on the placebo arm were given the opportunity to receive open-label sunitinib [see Clinical Studies (14.1)] .

For 241 patients randomized to the sunitinib arm, including 139 who received sunitinib in both the double-blind and open-label phases, the median duration of sunitinib treatment was 6 cycles (mean: 8.5; range: 1 to 44).

For the 255 patients who ultimately received open-label sunitinib treatment, median duration of study treatment was 6 cycles (mean: 7.8; range: 1 to 37) from the time of the unblinding.

Permanent discontinuation due to an adverse reaction occurred in 20% of patients who received sunitinib.

Dosage interruption occurred in 46% and dose reduction occurred in 28% of patients who received sunitinib.

Long-Term Safety in RCC The long-term safety of sunitinib 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 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 was evaluated in S-TRAC, a randomized, double-blind, placebo-controlled trial in which patients who had undergone nephrectomy for RCC received sunitinib 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 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 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.
