Webinar: Design of Clinical Trials To Evaluate Platelet Transfusion Efficacy and Safety
Platelet transfusion is an important supportive therapy for critically ill patients. As new methods for collecting, treating and storing platelet components are developed, how should they be evaluated in
Conducting a clinical trial for the evaluation of platelet transfusion efficacy requires that the objective be clear and that relevant endpoints are selected. Which is the best endpoint for this type of trial: count increment, hemostasis, clinical refractoriness, component utilization, transfusion interval? Also, which study design is the most appropriate; comparative, superiority, or non-inferiority?
In this presentation, Nancy Heddle, MSc. and Jeffrey McCullough, MD review a range of issues essential to the successful execution of a platelet clinical trial.
Some of the concepts addressed in this webinar are...
- A review of several trials including TRAP, SPRINT, and SToP. The study designs, data, and interpretations will be discussed
- SPRINT: conventional vs. INTERCEPT platelets (>300 pts/arm)
- SToP: standard vs. half-dose platelets (>800 pts total)
- TRAP: conventional vs. gamma-irradiated platelets (>500 pts)
- Requirements for properly statistically powering a study
- Understanding the PICOT methodology for study design
- Re-evaluating past trial data from new perspectives
