New trial design accounts for patient behavior

“Our work indicates that clinical trials underestimate the efficacy of a drug where behavior matters. It may be the case that 50% probability isn’t high enough for people to change any of their behaviors, especially if it’s a really uncertain new treatment. Then, it’s just going to look like the drug doesn’t work, and that isn’t the case.”

Because the meta-analysis supported the team’s hypothesis—that the interaction between treatment and behavior can have an effect on health outcomes—the next step is incorporating these new ideas into an active clinical trial.

Dr Snowberg said the best fit would be a drug trial for a condition, such as a mental health disorder or an addiction, that is known to be associated with behavior. At the very least, he hopes these results will lead the medical research community to a conversation about ways to improve the DBRCT.
