Abstract: The UCSF-Stanford Center of Excellence in Regulatory Science and Innovation (CERSI) The UCSF-Stanford Center of Excellence in Regulatory Science and Innovation (CERSI) brings together a world-class team of scientists from two outstanding academic institutions, with the goal of collaboratively supporting the FDA’s mission to protect the public’s health. Launched in 2014, our CERSI focuses on mission- driven regulatory science research—generating new knowledge that helps the FDA in its regulatory decision- making. Our research informs regulatory processes, guidances and policies relevant to the evaluation and monitoring of safe and effective medical products. The major goal of this two-year competing renewal application is to advance regulatory sciences primarily through collaborative research projects between scientists at the FDA and faculty at UCSF and Stanford. A secondary goal is to provide education and training to students, postdocs and scientists in medical product development. The research strategy includes four components. The first component is focused on our infrastructure, CERSI-Core. The goal of CERSI-Core is to support activities of the CERSI through effective management and oversight of the CERSI activities, monitoring financial transactions, reporting information to the FDA and key stakeholders, and scheduling interactive meetings. The second and third components of the research strategy is focused on research. Through strategic collaborative research among academic and FDA scientists, the overall goal of our CERSI research is to address key scientific issues for advancing FDA’s mission in protecting the public health. The second component consists largely of eight one-page proposals for research projects from investigators at UCSF and Stanford that address FDA’s priority areas for the CERSI program. These research projects are proposed for funding at the initiation of the renewal period. The third component includes 20 half-page research proposals that may be funded during the course of the two-year renewal period. Areas covered by one-page and half- page proposals include data analytics, clinical trial design, and digital health, among a broad range of research proposals. The fourth component consists of a plan for leveraging the FDA investment and procuring non- federal funds from private donors, our institutions, industry, and through our educational offerings. Finally, we include a short section on educational and outreach activities of our CERSI, which includes fellowship and scholarship programs, courses, workshops, meetings and other events. Collectively, the proposed continuing renewal application of the UCSF-Stanford CERSI will advance the FDA’s regulatory science goals.
