An Open-label, Randomized, Phase IIIb Trial Evaluating the Efficacy and Safety of Standard of Care +/- Continuous Bevacizumab Treatment Beyond Progression of Disease (PD) in Patients With Advanced Non-squamous Non-small Cell Lung Cancer (NSCLC) After First Line Treatment With Bevacizumab Plus a Platinum Doublet-containing Chemotherapy

This open-label, randomized, multicenter study will evaluate the efficacy and safety of bevacizumab (Avastin) in combination with standard of care (SOC) treatment in participants with advanced non-squamous NSCLC. Participants will be enrolled at documentation of progression of disease (PD) after 4-6 cycles of first-line treatment with bevacizumab plus a platinum doublet-containing therapy and a minimum of two cycles of bevacizumab maintenance treatment prior to PD. Participants will be randomly assigned to one of two treatment arms to receive either bevacizumab plus SOC treatment or SOC treatment alone.
