US Europe Japan Overall survival in randomized trials is the accepted standard for all recent approvals An intermediate position: randomized trials usually required, but other endpoints (i.e. RR, TTP and QoL) and/or methodologies (i.e. meta-analyses) utilized Objective response rate in non-randomized trials (with independent committee assessment) for all recent approvals Worldwide Endpointsfor Approval in Lung Cancer
