Trial Outcomes & Findings for Typhoid Vaccine in Testing Response to Immune Stress in Patients With Stage I-IIIA Breast Cancer (NCT NCT02415387)

NCT ID: NCT02415387

Last Updated: 2024-07-24

Results Overview

AUC change refers to the 'net incremental' area, which is the area under the curve above the baseline value. Data points used in AUC change calculation include baseline, 1.5, 3, 5, 6.5, 8 hours post vaccine. This can be calculated geometrically by applying the trapezoid rule. When a value falls below the baseline, only the area above the baseline level is included.

Any adverse events (AE) occurring during any part of the protocol will be reported immediately to the PI. A written report of all adverse events will be completed within 48 hours and submitted to the OSU IRB. Annually, IRB reports will include the occurrence of (un-) anticipated adverse events, and the timely progress of the trial, e.g. listing of all serious adverse events that occurred with clinical summaries, enrollment, withdraws, completions, etc.
