The last few years have seen a tremendous increase in the conduct of platform clinical trials, a type of randomized clinical trial that can simultaneously evaluate the effects of multiple interventions, often in combination, with the available treatments changing over time as more is learned about their effectiveness.

Lewis, MD, PhD, to discuss how clinicians should evaluate the results of platform clinical trials when considering incorporating the results into their clinical practice.
