In a late-breaker symposium on September 15, Christian Manegold, MD, Heidelberg University, Mannheim, Germany, said that progression-free survival in the Avastin in Lung Cancer (AVAIL) trial was 6.2 months in the placebo arm, 6.8 months with bevacizumab 7.5 mg/kg (P = .0003), and 6.6 months with 15 mg/kg dose of the drug (P = .0456). The trial recruited 1,050 patients with previously untreated stage IIIB or IV non-squamous-cell, non-small-cell lung cancer. Patients who had recurrent disease were also included. Dr. Manegold reported on 347 patients assigned to placebo, 345 to IV bevacizumab 7.5 mg/kg every 3 weeks, and 351 patients to IV bevacizumab 15 mg/kg every 3 weeks. He noted that overall survival was not significantly different between the placebo arm and either bevacizumab arm. He suggested that the study design, which allowed crossover to other lines of therapy after disease progression, could have diluted the possibility of finding a benefit in overall survival. "Overall survival was greater than 13 months in all arms of the study," he said "That is the longest overall survival ever reported in patients with advanced non-small-cell lung cancer," he said. After 30 months of treatment, median overall survival among patients in the bevacizumab 7.5 mg/kg arm was 13.6 months (P = .42), 13.4 months for patients on bevacizumab 15 mg/kg (P = .76), and 13.1 months for patients treated with placebo. All patients received background medication of the combination of cisplatin and gemcitabine. Funding for the AVAIL study was provided by F. Hoffman-LaRoche Ltd.
