Cooperative Participant Organization (CPO) Study Support for Trials Involving Healthy Participants

Partner with 1Day Sooner to advance your research and elevate participant-focused trials involving healthy volunteers

Our Cooperative Participant Organization (CPO) embeds 1Day Sooner staff scientists directly into study teams worldwide, especially in controlled human infection trials, to provide flexible support, accelerate recruitment, and integrate the voices of healthy participants throughout the research process. By aligning with the expectations of funders and regulators for meaningful public and participant involvement (PPI), we help make trials more efficient, participant-centered, and impactful.
