Patient-driven insight and design

We know patients have the clearest view of the burden of a study. To capture their insights, we engage patient advisors to evaluate trials for undue burdens and obstacles and can employ patient preference studies to inform clinical trial design and optimize participation. We also survey hundreds of patients each year about their clinical trial participation and specific protocol requirements. Patient input empowers us to refine protocol design for optimal recruitment and retention.
