What was measured

For participants who demonstrate CR or PR, DOR was defined as the time from first documented evidence of CR or PR until disease progression or death. The DOR per RECIST 1.1 as assessed by Investigator is presented.

Analysis population: All randomized participants based on the treatment group to which they were randomized who demonstrated CR or PR.

Groups in this outcome

Pembrolizumab+Chemotherapy

On Day 1 of each 21-day cycle, participants received an intravenous (IV) infusion of pembrolizumab 200 mg for up to 35 cycles (up to approximately 2 years) PLUS Investigator choice of chemotherapy for up to 6 cycles (paclitaxel 175 mg/m\^2 PLUS cisplatin 50 mg/m\^2 WITH or WITHOUT bevacizumab 15 mg/kg per local label OR paclitaxel 175 mg/m\^2 PLUS carboplatin Area Under the Curve (AUC) 5 for up to 6 cycles, WITH or WITHOUT bevacizumab 15 mg/kg per local label). All treatments were administered until disease progression or toxicity. Eligible participants who stopped the initial course of pembrolizumab with Stable Disease (SD) or better but progressed after discontinuation may have been able to initiate a second course of pembrolizumab for up to 17 cycles (up to approximately 1 additional year) at the investigator's discretion.

Placebo+Chemotherapy

On Day 1 of each 21-day cycle, participants received an IV infusion of placebo (Normal Saline or Dextrose solution) for up to 35 cycles (up to approximately 2 years) PLUS Investigator choice of chemotherapy for up to 6 cycles (paclitaxel 175 mg/m\^2 PLUS cisplatin 50 mg/m\^2 WITH or WITHOUT bevacizumab 15 mg/kg per local label OR paclitaxel 175 mg/m\^2 PLUS carboplatin AUC 5 for up to 6 cycles, WITH or WITHOUT bevacizumab 15 mg/kg per local label). All treatments were administered until disease progression or toxicity.
