Adverse Events Module
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

| eCTR Closed-Loop Control | The two modules of the eCTR are the SSM and an enhanced range control module based on an MPC algorithm that aims to maintain glycemia in a target range. eCTR also uses insulin-on-board constraints (29) intended to prevent insulin overdose during intensified therapy. The rationale behind MPC was presented in detail in a recent review (7). Controller aggressiveness was individualized for each subject based on readily available patient characteristics (e.g., body weight, insulin-to-carbohydrate ratio, and basal insulin delivery) (30). In this application, the MPC worked using information from the individual's conventional therapy. Premeal boluses were triggered by the patient, with the carbohydrate amount measured in the CRC kitchen but automatically calculated by eCTR. | None | None | 0 | 12 | 0 | 12 | View |
| Open-Loop | This admission was to assess the subjects' level of glucose control and created a base to compare the performance of the closed-loop system. Subjects monitored their own blood glucose values and administer their basal/bolus as they would at home. Subjects use their own pump. Otherwise, the admission remained the same as in the closed-loop admission (i.e. meals, exercise, etc...). | None | None | 0 | 38 | 2 | 38 | View |
| sCTR Closed-Loop Control | The two modules of sCTR are the SSM and a standard range control module that avoids prolonged hyperglycemic excursions. Both modules use a real-time estimate of the patient 's metabolic state based on CGM and insulin infusion data. This estimate is used for prediction of the risks of hypo-and hyperglycemia 30-45 min ahead of the event. If a risk for hypoglycemia is predicted, the SSM attenuates automatically any insulin requests proportionally to the predicted risk level. How aggressively the system attenuates insulin is determined with patient characteristics (e.g., body weight, insulin-to-carbohydrate ratio, and basal insulin delivery). If a risk for hyperglycemia is predicted, the range controller gives a correction bolus using the predicted plasma glucose and the patient's CSII parameters; the system injects only half of the computed bolus and can do so once every hour. | None | None | 0 | 26 | 2 | 26 | View |
