Is there anything in the design of a valve trial that you foresee as a source of difficulty when it comes to executing?

Q&A with Thelma Bueno, Sr. Clinical Project Manager at genae Americas

Q: Is there anything in the design of a valve trial that you foresee as a source of difficulty when it comes to executing?

A: Device trial designs which compare very different types of procedures, are susceptible to imbalances in treatment adherence and follow-up because some participants may have a strong preference for one therapy and because blinding is not feasible. 

Since incomplete treatment adherence could bias results toward a conclusion of noninferiority, analyses of both the intention-to-treat cohort and the cohort restricted to participants who received the assigned therapy (the as-treated cohort) have been important for these studies.
