What was measured

Depth of Response (percent change from Baseline in tumor diameter) is defined as the relative percent change in the sum of the longest diameters of RECIST 1.1 target lesions (TL) at the nadir in the absence of new lesions or progression of non-target lesions (NTL) compared to baseline. The best percentage change in TL size is the maximum reduction from baseline or the minimum increase from baseline in the absence of a reduction. Tumor assessments of the chest and abdomen (including the entire liver and both adrenal glands) were performed using RECIST 1.1 by the investigator on images from CT (preferred) or MRI with IV contrast. Per the protocol, the safety run-in treatment arms were combined and analyzed regardless of chemotherapy received for consistency with the randomized component.

Analysis population: Safety Analysis Set, includes all participants in the Safety Run-In Treatment Arms who received at least 1 dose of study treatment (osimertinib, cisplatin, carboplatin, or pemetrexed).
