[Correspondence] Go, no-go decision making for phase 3 clinical trials: ACT IV revisited – Authors' reply
We appreciate not only the interest of H Ian Robins and colleagues in the ACT IV trial,1 but also the thoughtful commentary by Elizbeth R Gerstner. From the perspective of several years' additional experience with clinical trial conduct in newly diagnosed glioblastoma relative to the time when ACT IV was designed, we feel that the failure to adequately estimate efficacy with a new treatment based on historical controls (even when matched for eligibility) provides a good lesson to be learned.
