Brief summary
This is a placebo-controlled, double-blind, multicenter, randomized study for preliminary evaluation of the efficacy and safety of combining bevacizumab with cisplatin (or carboplatin) and etoposide in patients with previously untreated extensive-stage small cell lung cancer (SCLC).
Interventions
Bevacizumab 15 mg/kg by intravenous (IV) infusion on Day 1 of each of the first four 21-day cycles during chemotherapy, followed by single agent administration until disease progression, unacceptable toxicity, discontinuation from study, or death.
Chemotherapy = cisplatin (or carboplatin) + etoposide. Cisplatin 75 mg/m² IV on Day 1 of each of the first four 21-day cycles OR carboplatin (area under the curve \[AUC\]=5 mg/mL/min, per Calvert formula) IV on Day 1 of each of the first four 21-day cycles; etoposide 100 mg/m² on Days 1-3 of each of the first four 21-day cycles.
Placebo 15 mg/kg by intravenous (IV) infusion on Day 1 of each of the first four 21-day cycles during chemotherapy, followed by single agent administration until disease progression, unacceptable toxicity, discontinuation from study, or death.
