First-line Treatment of Patients With Stage IV Nonsquamous Non-Small Cell Lung Cancer With Necitumumab (IMC-11F8) and Pemetrexed-Cisplatin

Multinational, randomized, multicenter, open-label Phase 3 study of 633 participants with advanced, nonsquamous (Stage IV) NSCLC. Participants will be randomized on a 1:1 basis to receive first-line necitumumab plus chemotherapy consisting of pemetrexed and cisplatin in study Arm A, or first-line pemetrexed-cisplatin chemotherapy alone in Arm B. Baseline radiographic assessment of disease will be performed within 21 days prior to randomization (first treatment will be administered within 7 days following randomization). Participants will undergo radiographic assessment (computed tomography or magnetic resonance imaging) of disease status every 6 weeks (± 3 days), until there is radiographic documentation of progressive disease (PD). Chemotherapy will continue for a maximum of six cycles in each arm (Or until there is radiographic documentation of PD, toxicity requiring cessation, protocol noncompliance or withdrawal of consent); participants in Arm A only will continue to receive necitumumab until there is radiographic documentation of PD, toxicity requiring cessation, protocol noncompliance, or withdrawal of consent. After the end-of-study-visit (following PD), follow-up information regarding further anticancer treatment and survival will be collected every 2 months (± 7 days). For participants who discontinue study for reasons other than PD (eg, symptomatic deterioration), information on disease progression will also be collected until PD is documented. Follow-up will continue as long as the participant is alive, or until the end of the trial.
