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

| Chemoradiotherapy + Placebo, Followed by Placebo | Participants received radiotherapy once daily (OD), with a dose/fraction less than 2.5 Gray (Gy) to a total dose of 70 Gy (using two-dimensional \[2D\] or 3D techniques) or 65 Gy (using Intensity Modulated Radiation Therapy \[IMRT\]) to the gross site of disease. Concurrent chemotherapy of cisplatin 100 milligrams per meters squared (mg/m\^2) was administered intravenously (IV) on Days 1, 22, and 43 of the course of radiotherapy (Study Days 8, 29, and 50). Matching placebo administration commenced 1 week (or less than or equal to 3 days) prior to the concurrent administration with chemoradiation for a duration of up to 6 to 7 weeks. After the completion of chemoradiotherapy, placebo monotherapy was administered until disease progression or withdrawal. | None | None | 18 | 31 | 31 | 31 | View |
| Chemoradiotherapy + Lapatinib, Followed by Lapatinib | Participants received radiotherapy once daily (OD), with a dose/fraction less than 2.5 Gy to a total dose of 70 Gy (using 2D or 3D techniques) or 65 Gy (using IMRT) to the gross site of disease. Concurrent chemotherapy of cisplatin 100 mg/m\^2 was administered IV on Days 1, 22, and 43 of the course of radiotherapy (Study Days 8, 29, and 50). Lapatinib 1500 mg OD administration commenced 1 week (or less than or equal to 3 days) prior to the concurrent administration with chemoradiation for a duration of up to 6 to 7 weeks. After the completion of chemoradiotherapy, lapatinib 1500 mg OD monotherapy was administered until disease progression or withdrawal. | None | None | 22 | 35 | 34 | 35 | View |
