Non-Small Cell Lung Cancer

Brief summary

The purpose of study is to compare the efficacy and safety of ONO-4538 in combination with carboplatin, paclitaxel, and bevacizumab (ONO-4538 group) to placebo in combination with carboplatin, paclitaxel, and bevacizumab (placebo group) in chemotherapy-naïve subjects with stage IIIB/IV or recurrent non-squamous non-small cell lung cancer unsuitable for radical radiation in a multicenter, randomized, double-blind study.

Interventions

360 mg solution intravenously for 30 min in every 3 weeks until RECIST 1.1 defined PD, unacceptable toxicity, or withdrawal of consent.

DRUGCarboplatin

Carboplatin at AUC 6 and Paclitaxel at 200 mg/m2 intravenously in every 3 weeks for up to 4 cycles and if deemed safe, Carboplatin and Paclitaxel may continue for up to a maximum of 6 cycles until RECIST 1.1 defined PD, unacceptable toxicity, or withdrawal of consent.

DRUGPaclitaxel

Carboplatin at AUC 6 and Paclitaxel at 200 mg/m2 intravenously in every 3 weeks for up to 4 cycles and if deemed safe, Carboplatin and Paclitaxel may continue for up to a maximum of 6 cycles until RECIST 1.1 defined PD, unacceptable toxicity, or withdrawal of consent.

DRUGBevacizumab

Bevacizumab at 15 mg/kg intravenously in every 3 weeks until RECIST 1.1 defined PD, unacceptable toxicity, or withdrawal of consent.

DRUGPlacebo

Placebo solution intravenously for 30 min in every 3 weeks until RECIST 1.1 defined PD, unacceptable toxicity, or withdrawal of consent.

Design outcomes

Primary

MeasureTime frameDescription
Progression Free Survival (PFS) as Assessed by the Independent Radiology Review Committee (IRRC)Approximately 32 monthsPFS (as assessed by the IRRC) will be calculated using the following formula : PFS (days) = date when overall response is assessed as progressive disease (PD) or date of death (for any reason), whichever comes first - date of randomization + 1. Please refer to the protocol, in this study, tumor response will be evaluated by CT, etc. according to the RECIST 1.1 criteria.

MeasureTime frameDescription
Overall Survival (OS)Approximately 32 months
Objective Response Rate (ORR [as Assessed by the IRRC])Approximately 32 monthsORR represents the proportion of subjects whose best overall response was assessed as complete response (CR) or partial response (PR). Please refer to the protocol, in this study, tumor response will be evaluated by CT, etc. according to the RECIST 1.1 criteria.

Progression Free Survival (PFS) as Assessed by the Independent Radiology Review Committee (IRRC)
