Study of BMS-936558 (Nivolumab) Compared to Docetaxel in Previously Treated Advanced or Metastatic Squamous Cell Non-small Cell Lung Cancer (NSCLC) (CheckMate 017)

Time To Response (TTR) in Months for All Confirmed Responders

Time to Response (TTR) 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.

Time frame: From the date of randomization to the date of the first confirmed response, up to approximately 12 months

Duration of Objective Response (DOR) in Months for All Confirmed Responders

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.

Time frame: From the date of first confirmed response to the date of the first documented tumor progression or death due to any cause, whichever occurred first, up to approximately 94 months

Progression Free Survival Rate (PFSR)

PFSR was defined as the percentage of participants who did not experience disease progression or death from any cause at a given time point following randomization. Progression was assessed by investigators according to RECIST v1.1. Participants who did not progress or die were censored on the date of their last evaluable tumor assessment. Participants who started any subsequent anti-cancer therapy (including on-treatment palliative radiation therapy (RT) of non-target bone lesions or CNS lesions) without a prior reported progression were to be censored at the last evaluable tumor assessment prior to or on initiation of the subsequent anti-cancer therapy.

Time frame: From randomization to specified timepoints, up to 84 months

Progression-Free Survival (PFS) Time in Months for All Randomized Participants

PFS was defined as the time from the date of randomization to the date of the first documented tumor progression as determined by the investigator per RECIST v1.1 criteria, or death due to any cause. Participants underwent radiographic tumor assessments every 6 weeks (+/- 5 days) from week 9 (+/- 5 days) for the first year on treatment, then every 12 weeks after the first year on treatment until documented disease progression. The PFS curves were estimated using KM method. Two-sided 95% CI for median PFS were computed by Brookmeyer and Crowley method (using log-log transformation). Participants who did not progress or die were censored on the date of their last evaluable tumor assessment. Participants who started any subsequent anti-cancer therapy (including on-treatment palliative RT of non-target bone lesions or CNS lesions) without a prior reported progression were to be censored at the last evaluable tumor assessment prior to or on initiation of the subsequent anti-cancer therapy.

Time frame: From randomization up to the first confirmed response to the date of the first documented tumor progression or death due to any cause, whichever occurred first, up to approximately 103 months

Percentage of Participants Experiencing Disease-related Symptom Improvement by Week 12

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.

Time frame: From randomization up to Week 12

Overall Survival (OS) Time in Months by Baseline PD-L1 Expression for All Randomized Participants

OS was measured in months for all randomized participants grouped by their baseline PD-L1 expression level. PD-L1 expression was defined as the percent of disease tumor cells demonstrating plasma membrane PD-L1 staining of any intensity using an immunohistochemistry (IHC) assay. OS was defined as the time between the date of randomization and the date of death from any cause. Participants were censored at the date they were last known to be alive. Median OS time was calculated using Kaplan-Meier (KM) method.

Time frame: From the date of randomization to the date of death from any cause, up to approximately 103 months

Objective Response Rate (ORR) by Baseline PD-L1 Expression for All Randomized Participants

ORR was reported for all randomized participants grouped by their baseline PD-L1 expression level. 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). 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. 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. CIs were computed using the Clopper and Pearson method.

Time frame: From the date of randomization up to the date of objectively documented progression, up to approximately 103 months

Progression Free Survival (PFS) Time in Months by Baseline PD-L1 Expression for All Randomized Participants

PFS time was measured for all randomized participants grouped by their baseline PD-L1 expression levels. PFS was defined as the time from the date of randomization to the date of the first documented tumor progression as determined by the investigator per RECIST v1.1 criteria, or death due to any cause. The PFS curves were estimated using KM method. Participants who did not progress or die were censored on the date of their last evaluable tumor assessment. Participants who started subsequent anti-cancer therapy (including on-treatment palliative radiotherapy of non-target bone lesions or CNS lesions) without a prior reported progression were censored at the last evaluable tumor assessment prior to subsequent anti-cancer therapy.

Time frame: From the date of first confirmed response to the date of the first documented tumor progression or death due to any cause, whichever occurred first, up to approximately 103 months
