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
| Title | Description | Deaths # Affected | Deaths # At Risk | Serious # Affected | Serious # At Risk | Other # Affected | Other # At Risk | View |
|---|---|---|---|---|---|---|---|---|
| Cohort A: MK-3475 (Pembrolizumab) | Resectable patients receive pembrolizumab IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 3 cycles. Patients with potentially resectable disease undergo surgery. Patients with tumor progression and unresectable disease may receive one additional cycle of pembrolizumab. | 5 | None | 1 | 29 | 23 | 29 | View |
| Cohort B: MK-3475 (Pembrolizumab) | Unresectable patients receive pembrolizumab IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 34 cycles in the absence of disease progression or toxicity. | 10 | None | 14 | 27 | 25 | 27 | View |
