Designing and conducting a clinical trial in blood and marrow transplantation.

Clinical trials form the cornerstone of the science-based approach to improving patient outcomes. A trial needs to be designed and performed carefully to provide valid evidence to inform medical science and to protect the safety and well-being of its participants. The development of a clinical trial involving blood and marrow transplant (BMT) requires special considerations, including the rare disease populations involved and transplant-specific outcomes of interest that necessitate appropriate analysis techniques to evaluate. This article reviews key considerations and best practices for the design and conduct of a clinical trial in BMT, including the selection of patient population, treatment groups, objectives and endpoints, targeted sample size, statistical analysis strategy, provisions for monitoring patient safety and trial progress, and dissemination of trial results. The practical application of these principles is demonstrated using BMT CTN 1301, a recently completed clinical trial evaluating regimens for chronic graft-versus-host disease prevention in transplant patients.
