For researchers submitting trial data to ClinicalTrials.gov, the Adverse Events module is one of four mandatory results sections. It requires reporting in three primary categories: All-Cause Mortality: A table tracking all deaths that occurred during the study, regardless of cause. Serious Adverse Events (SAEs): A tabular summary of events resulting in death, life-threatening conditions, hospitalization, or significant disability. Other Adverse Events: A table for non-serious events that exceed a specific frequency threshold, such as 5% within any study arm.
Adverse Events Module path is as follows:
Study -> Results Section -> Adverse Events Module -> Event Groups
Study -> Results Section -> Adverse Events Module -> Serious Events
Study -> Results Section -> Adverse Events Module -> Other Events

| Cohort A: Pembrolizumab First Course | Participants in Cohort A previously received at least one prior systemic treatment for metastatic breast cancer. Participants were administered pembrolizumab 200 mg intravenously (IV) on Day 1 of each 3-week cycle (Q3W) for up to 35 cycles (up to \~2 years). | 154 | None | 46 | 170 | 147 | 170 | View |
| Cohort A: Pembrolizumab Second Course | Qualified Cohort A participants who completed the first course of up to 35 administrations of pembrolizumab (\~2 years) but progressed after discontinuation, initiated a second course of pembrolizumab at the investigator's discretion, at the same dose and schedule at 200 mg IV on Day 1 each 3-week cycle (Q3W) for up to 17 cycles (up to \~1 year). | 0 | None | 0 | 1 | 1 | 1 | View |
| Cohort B: Pembrolizumab First Course | Participants in Cohort B previously received no prior systemic treatment for metastatic breast cancer AND had a programmed cell death-ligand 1 (PD-L1) positive tumor expression. Participants were administered pembrolizumab 200 mg IV on Day 1 of each 3-week cycle (Q3W) for up to 35 cycles (up to \~2 years). | 63 | None | 19 | 84 | 79 | 84 | View |
