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

| Arm 2, Cetuximab, Gemcitabine and Cisplatin | Gemcitabine, Cisplatin and Cetuximab: Cisplatin will be administered intravenously at a dose of 70 mg/m2 per institutional standards on Day 1 of each cycle. Gemcitabine will be administered intravenously at a dose of 800 mg/m2 on Days 1, 8 and 15 of cycle. Cetuximab will be administered intravenously at a dose of 500 mg/m2 on Days 1 and 15 of each cycle. One treatment cycle is 28 days. | None | None | 36 | 60 | 60 | 60 | View |
