Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetic Parameter Area Under the Concentration Versus Time Curve of Geometric Means of Serum Free Form of CS-7017 (R-150033) After Administration of CS-7017 and Carboplatin/Paclitaxel in Participants With Stage IIIb/IV Non-small Cell Lung Cancer | The area under the concentration versus time curve during dosing interval (AUCtau) and up to the last quantifiable time (AUClast) of geometric means of CS-7017 are reported at selected cycles (C) and days (D). | Initial C1D1, C2D22 and additional C1D3, C2D22 predose, 0.5, 1, 2, 3, 4, 6 and 10h; initial and additional D8 predose; additional D1 predose and 3h; initial and additional D15 predose and 1-3h; C3D43 and C4D64 any time, except additional C3D43 predose | 
| Pharmacokinetic Parameter Observed Serum Concentration (Cmax) of Geometric Means of Serum Free Form of CS-7017 (R-150033) Following Administration of CS-7017 and Carboplatin/Paclitaxel in Participants With Stage IIIb/IV Non-small Cell Lung Cancer | The maximum serum concentration (including at steady state (ss) of CS-7017 are reported at selected cycles (C) and days (D). | Initial C1D1, C2D22 and additional C1D3, C2D22 predose, 0.5, 1, 2, 3, 4, 6 and 10h; initial and additional D8 predose; additional D1 predose and 3h; initial and additional D15 predose and 1-3h; C3D43 and C4D64 any time, except additional C3D43 predose |

| Treatment-Emergent Adverse Events Occurring in Participants in Any Treatment Group During Cycle 1 Following Administration of CS-7017 and Carboplatin/Paclitaxel in Participants With Stage IIIb/IV Non-small Cell Lung Cancer | Treatment-emergent adverse events (TEAEs) are defined as those adverse events that occur, having been absent before the study, or worsen in severity after the initiation of study drug. | Baseline to end of Cycle 1, with each treatment cycle being 3 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Best Overall Response and Objective Response Rate Following Administration of CS-7017 in Combination With Carboplatin/Paclitaxel in Chemotherapy-naïve Subjects With Metastatic or Unresectable Locally Advanced Non-small Cell Lung Cancer (NSCLC) | The best overall response is the best response (in the order of confirmed complete response [CR], confirmed partial response [PR], stable disease [SD], and progressive disease [PD]) among all overall responses from the start of treatment until the participant withdraws from the study. Participants who did not have a tumor assessment, the best overall response is Not Evaluable (NE). The response rate was defined as the proportion of participants with a best overall response of CR or PR, ie, [confirmed and unconfirmed, (CR + PR) / number of participants]. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions, CR was defined as the disappearance of all target lesions, PR was defined as ≥30% decrease in the sum of diameters of target lesions, PD was defined as ≥20 increase in the smallest sum of diameters, and SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. | Baseline up to Week 18 postdose | 
| CS-7017-Related Treatment-Emergent Adverse Events Occurring in Participants in Any Treatment Group After Administration of CS-7017 and Carboplatin/Paclitaxel in Chemotherapy-naïve Participants With Stage IIIb/IV Non-small Cell Lung Cancer | Treatment-emergent adverse events (TEAEs) are defined as those adverse events that occur, having been absent before the study, or worsen in severity after the initiation of study drug. CS-7017-related TEAEs are those TEAEs that are related to CS-7017 in the relationship. | Baseline to 30 days after last dose, up to approximately 1 year |
