BACKGROUND: Results of two phase 3 trials have shown first-line bevacizumab in combination with chemotherapy improves clinical outcomes in patients with advanced or recurrent non-squamous non-small-cell lung cancer (NSCLC). The SAiL (MO19390) study was undertaken to assess the safety and efficacy of first-line bevacizumab combined with standard chemotherapy regimens in clinical practice.
METHODS: Between August, 2006, and June, 2008, patients with untreated locally advanced, metastatic, or recurrent non-squamous NSCLC were recruited to this open-label, single group, phase 4 study from centres in 40 countries. Eligible patients had histologically or cytologically documented inoperable, locally advanced, metastatic, or recurrent disease (stage IIIB-IV); an Eastern Cooperative Oncology Group performance status of 0-2; and adequate haematological, hepatic, and renal function. Patients received bevacizumab (7.5 or 15 mg/kg every 3 weeks) plus standard chemotherapy for up to six cycles, followed by single-agent bevacizumab until disease progression. The primary endpoint was safety; analysis was by intention to treat (ITT). This study is registered with ClinicalTrials.gov, number NCT00451906.
FINDINGS: At the final data cutoff (July 24, 2009), an ITT population of 2212 patients was assessed. The incidence of clinically significant (grade>or = 3) adverse events of special interest was generally low; thromboembolism occurred in 172 (8%) patients, hypertension in 125 (6%), bleeding in 80 (4%), proteinuria in 67 (3%), and pulmonary haemorrhage in 15 (1%). 57 (3%) patients died because of these adverse events, with thromboembolism (26 patients, 1%) and bleeding (17, 1%) as the most common causes. The most common grade 3 or higher serious adverse events deemed by investigators to be associated with bevacizumab were pulmonary embolism (28 patients; 1%) and epistaxis, neutropenia, febrile neutropenia, and deep vein thrombosis (all of which occurred in 13 patients [1%]). Bevacizumab was temporarily interrupted after 28 (2%) of 1347 bleeding events and 72 (7%) of 1025 hypertension events, and permanently discontinued after 110 (8%) bleeding events and 40 (4%) hypertension events. No new safety signals were reported.
INTERPRETATION: Our results confirm the manageable safety profile of first-line bevacizumab in combination with various standard chemotherapy regimens for treatment of advanced non-squamous NSCLC.
