Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Cohort A - Pembrolizumab 200 mg | Participants were previously treated with standard therapies, which must include fluoropyrimidine, oxaliplatin, and irinotecan. Cohort A participants received pembrolizumab 200 mg intravenously (IV) on Day 1 of every 3-week cycle (Q3W) for up to approximately 35 cycles (up to approximately 2 years). | 60 | 61 | OG000 |
| Group 2 | Cohort B - Pembrolizumab 200 mg | Participants were previously treated with at least one line of systemic standard of care therapy: fluoropyrimidine + oxaliplatin or fluoropyrimidine + irinotecan +/ - anti vascular endothelial growth factor (VEGF)/ epidermal growth factor regulator (EGFR) monoclonal antibody. Cohort B participants received pembrolizumab 200 mg IV on Day 1 Q3W for up to approximately 35 cycles (up to approximately 2 years). | 63 | 63 | OG001 |
