Trials Terminated Early
· 2026-09-01 · 原文
What does it mean to stop a clinical trial early? In the early days of the modern randomized trial, it meant the research had not gone according to plan. Trialists were expected to adhere to the sample sizes they originally proposed based on early assumptions about underlying event rates, loss to follow-up, and variability in outcomes. When a trial was stopped prematurely, it indicated that foundational assumptions had proven incorrect, critical safety or protocol issues had emerged, or logistical challenges had grown insurmountable. Early trial termination carried an implicit presumption of failure: that the trial had been inadequately planned, poorly executed, or simply overtaken by circumstances beyond investigators’ control.
