What was measured

Overall response rate is the best response of CR or PR as classified by the investigators according to the Response Evaluation Criteria in Solid Tumors (RECIST, v1.1) guidelines. CR is defined as the disappearance of all target and non-target lesions, normalization of tumor marker level of non-target lesions, and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 millimeter (mm). PR is an at least 30% decrease in the sum of the diameters of target lesions (taking as reference the baseline sum diameter) without progression of non-target lesions or appearance of new lesions. Overall response rate is calculated as a total number of participants with CR or PR divided by the total number of participants with at least 1 measurable lesion, multiplied by 100.

Analysis population: All randomized Phase 2 participants.

Groups in this outcome

Phase 2: Pemetrexed + Cisplatin + LY2603618

Cycles 1-4 (21-day cycle): Before 25 Oct 2012: Day 1: pemetrexed 500 mg/m\^2 + cisplatin 75 mg/m\^2 Day 2: LY2603618 dose determined from phase 1 (275 mg) After 25 Oct 2012: Day 1: pemetrexed 500 mg/m\^2 + cisplatin 75 mg/m\^2 After 4 cycles, participants may have continued on maintenance therapy until disease progression, unacceptable toxicity, or other withdrawal criterion was met. Maintenance therapy (every 21 days): Before 25 Oct 2012: Day 1: pemetrexed 500 mg/m\^2 Day 2: LY2603618 dose determined from phase 1 (275 mg) After 25 Oct 2012: Day 1: pemetrexed 500 mg/m\^2 If, as of 25 Oct 2012, the participant was in maintenance therapy and randomized to the experimental arm, the participant was eligible to continue with pemetrexed/LY2603618 therapy if the investigator deemed it was in the participant's best interest and the participant consented. Pemetrexed, cisplatin, and LY2603618 were administered IV over 10 minutes, 1 hour, and 1 hour, respectively.

Phase 2: Pemetrexed + Cisplatin

Cycles 1-4 (21-day cycle): Day 1: pemetrexed 500 mg/m\^2 + cisplatin 75 mg/m\^2 After 4 cycles, participants may have continued on maintenance therapy until disease progression, unacceptable toxicity, or other withdrawal criterion was met. Maintenance therapy (every 21 days): Day 1: pemetrexed 500 mg/m\^2 Pemetrexed was administered IV over 10 minutes, and cisplatin was administered IV over 1 hour.
