Guardian Research Network

Accelerating Cures for Cancer

About Us


Guardian Research Network is an oncology-focused, mission-driven hospital consortium. Our mission is to bring unprecedented access to cutting-edge trials and revolutionary clinical research to under-served communities. We partner with high performing integrated hospital systems who unite to create the country’s deepest cancer data warehouse. Our priority is to enable and execute the next generation of clinical trials. Our experienced team provides GRN members and our biopharma partners with deep insight into cancer care through our data analytics platform.

  • Identifying the right patients at the right time for clinical trials placed at our member network hospitals.
  • Collaborating with industry on its development and commercialization activities around therapeutic and diagnostic trials.
  • Optimizing your study’s efficiency and quality with our proprietary technology that minimizes the need for traditional manual source data verification and data management.



Guardian Research Network collaborates with community hospitals around the U.S. to organize patient data and to match cancer patients to cancer trials with greater ease and efficiency than traditional methods. We are motivated by efficient trial launching, faster patient enrollment, and ushering in potential cancer cures that will improve and change patients’ lives.
