Study of BMS-936558 (Nivolumab) Compared to Docetaxel in Previously Treated Metastatic Non-squamous NSCLC

Overall survival was defined as the time from randomization to the date of death. A participant who has not died will be censored at last known date alive. OS will be followed continuously while participants are on the study drug and every 3 months via in-person or phone contact after participants discontinue the study drug. Median and hazard ratio computed using Kaplan-Meier method.

ORR was defined as the percentage of participants whose Best Overall Response (BOR) was a confirmed Complete Response (CR) or Partial Response (PR). BOR was defined as the best investigator-assessed response designation, recorded between the date of randomization and the date of objectively documented progression per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) or the date of subsequent anti-cancer therapy (excluding on-treatment palliative radiotherapy of non-target bone lesions or Central Nervous System (CNS) lesions), whichever occurred first. CR = Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm. PR = At least a 30% decrease in the sum of diameters of target lesions, taking, as reference, the baseline sum diameters. CR+PR, confidence interval based on the Clopper and Pearson method.

Time to Objective Response for participants demonstrating a response (either CR or PR) was defined as the time from the date of randomization to the date of the first confirmed response. CR = Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm.; PR = At least a 30% decrease in the sum of diameters of target lesions, taking, as reference, the baseline sum diameters.

DOR was defined as the time from the date of first confirmed response to the date of the first documented tumor progression (per RECIST v1.1), as determined by the investigator, or death due to any cause, whichever occurred first. DOR was evaluated only for confirmed responders (i.e. participants with confirmed CR or PR). CR = Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm.; PR = At least a 30% decrease in the sum of diameters of target lesions, taking, as reference, the baseline sum diameters. Participants who neither progressed nor died were censored on the date of their last evaluable tumor assessment. Median computed using Kaplan-Meier method.

PFS was defined as the time from randomization to the date of the first documented tumor progression (per RECIST 1.1) or death due to any cause. Participants who died without a reported prior progression were considered to have progressed on the date of their death. Progression will be assessed every 6 weeks (from the first on-study radiographic assessment) until disease progression is noted. Progressive disease was defined as least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered progression. Median computed using the Kaplan-Meier method.

Disease-related symptom improvement rate by Week 12 was defined as the percentage of randomized participants who had a 10 point or greater decrease from baseline in average symptom burden index score at any time between randomization and Week 12. The participant portion of the Lung Cancer Symptom Scale (LCSS) consisted of 6 symptom-specific questions that addressed cough, dyspnea, fatigue, pain, hemoptysis, and anorexia, plus 3 summary items on symptom distress, interference with activity level, and global health-related Quality of Life (QoL). The scores range from 0 to 100, with 0 representing the best possible score and 100 being the worst possible score. The average symptom burden index score at each assessment was defined as the mean of the 6 symptom-specific questions of the LCSS. 95% CIs were computed using Clopper-Pearson Method.

Overall survival was defined as the time from randomization to the date of death. A participant who has not died will be censored at last known date alive. Overall Survival time was measured in months for all randomized participants grouped by their baseline PD-L1 expression level. PD-L1 expression in participants was defined as the percent of disease tumor cells demonstrating plasma membrane PD-L1 staining of any intensity using an immunohistochemistry (IHC) assay. Median computed using the Kaplan-Meier method.

ORR was defined as the percentage of all randomized participants whose Best Overall Response (BOR) was a confirmed Complete Response (CR) or Partial Response (PR). CR = Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to < 10 mm.; PR = At least a 30% decrease in the sum of diameters of target lesions, taking, as reference, the baseline sum diameters. CR+PR, confidence interval based on the Clopper and Pearson method. ORR was reported for all randomized participants grouped by their baseline PD-L1 expression level. PD-L1 expression in participants was defined as the percent of disease tumor cells demonstrating plasma membrane PD-L1 staining of any intensity using an immunohistochemistry (IHC) assay.
