| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Pembrolizumab | Participants received pembrolizumab 200 mg IV on Day 1 Q3W. Eligible participants who stopped pembrolizumab with Stable Disease (SD) or better but progressed after discontinuation may have been able to initiate a second course of pembrolizumab 200 mg IV Q3W for up to 17 cycles (up to approximately 1 additional year). | 28 | 266 | OG001 |
| Group 2 | Control | Participants received paclitaxel 175 mg/m\^2 intravenously (IV) or docetaxel 75 mg/m\^2 IV or vinflunine 320 mg/m\^2 IV, on Day 1 of each 3-week cycle (Q3W). Eligible participants who experienced disease progression may have been able to switch over to receive pembrolizumab 200 mg IV Q3W for up to 35 treatment administrations (up to approximately 2 years). | 36 | 255 | OG000 |

The number of participants who discontinued study treatment due to an AE was reported for each arm.
- Time frame
- Through final analysis database cut-off date of 26-Oct-2017 (Up to approximately 34 months)
- Population
