Following the recent publication of their review article Adaptive Designs for Clinical Trials in the New England Journal of Medicine,  co-authors Cyrus Mehta ( President and Co-Founder of Cytel, and Adjunct Professor of Biostatistics at Harvard University) and Deepak L. Bhatt M.D C M.P.H. (Executive Director of Interventional Cardiovascular Programs, Brigham and Women’s Hospital Heart and Vascular Center) were invited to participate in a live video discussion with the journal.

Operational and regulatory considerations in a promising zone trial

Posted by Cytel

Aug 9, 2016 9:00:00 AM

At the recent JSM Meeting, Cytel’s Yannis Jemiai presented the case study of the VALOR trial which used a promising zone design. At the time of the study, existing therapy for relapsed or refractory AML was generally unsatisfactory with no approved drugs available for patients, and a very poor prognosis.  Vosaroxin was a first-in-class anticancer quinolone derivative which had previously been studied in a single arm Phase 2 study. In this blog we'll take a look at the operational and regulatory considerations in the implementation of this trial, which were highlighted during Jemiai's talk.

 Predicting the course of a clinical trial is something which people will always want to do-whether for statistical reasons, planning reasons or business reasons. In this blog we look at examples of where prediction goes off course, and how we can resolve these issues.  We also share valuable video and slidedeck resources from our VP Consulting and Software, Yannis Jemiai.
