Veliparib Plus Carboplatin and Paclitaxel Versus Investigator's Choice of Standard Chemotherapy in Patients With Advanced Non-Squamous Non-Small Cell Lung Cancer.

Background: This open-label Phase III trial (NCT02264990) evaluated the PARP inhibitor, veliparib, combined with carboplatin/paclitaxel versus chemotherapy alone for first-line treatment of patients with advanced non-squamous non-small cell lung cancers (NSCLC). A 52-gene expression classifier (LP52) previously shown to identify patients more likely to respond to veliparib was evaluated as a planned correlative analysis.

Materials And Methods: Adult current or former smokers with advanced non-squamous NSCLC were randomized 1:1 to veliparib (120 mg daily for 7 days/cycle) with carboplatin and paclitaxel or to investigators' choice of platinum doublet chemotherapy (up to 6, 21-day cycles), with optional pemetrexed maintenance.
