More Info

A platform trial is a type of randomized controlled trial (RCT). It is sometimes called a Master Protocol. This is because a platform trial uses Master Protocol to test the different study treatments in the same way, using the same design.

A platform trial is done to compare multiple treatments or interventions by comparing them against each other and a control.

This is a way to do research more efficiently with fewer patients to find an answer. As a platform trial progresses, the research team may add new study treatments to compare and remove ones that are not working or have too many adverse events.
