Radiopharmaceutical Development Initiative (RDI)

Overview/Objectives

As part of NCI’s overall drug development efforts in collaboration with the pharmaceutical industry and academic investigators, NCI has developed a specialized infrastructure, the Radiopharmaceutical Development Initiative (RDI), for the clinical evaluation of novel theranostic radiopharmaceutical cancer therapies. The focus of NCI’s efforts is to complement industry development of these agents with early phase combination studies to test tolerability and early signs of efficacy of radiopharmaceutical agents in combination with other novel agents that may add to their clinical benefit.

The objectives of the RDI are to:

  • Conduct early or late phase clinical trials in NCI-funded clinical networks, especially in the Experimental Therapeutics Clinical Trials Network, of NCI-IND radiopharmaceutical agents in combination with other agents in high priority areas of unmet medical needs
  • Study dosimetry and radiobiology findings through novel clinical biomarker analyses
  • Integrate molecular characterization, pharmacology, cancer biology, and theranostic or dosimetry imaging into radiopharmaceutical-based clinical trials.

See links above for more information on the RDI and the Experimental Therapeutics Clinical Trials Network (ETCTN) or National Clinical Trials Network (NCTN).

RDI Infrastructure

RDI radiopharmaceutical-based trials are supported by integrated centralized clinical and administrative services sponsored by NCI according to the diagram below. For early phase clinical trials of NCI-IND radiopharmaceutical agents, more details and links to services, may be found here.

RDI White Papers

NCI RDI initiatives consider radiopharmaceutical cancer treatment as any radionuclide administered by vein, injection, inhalation, or ingestion that is intended to irradiate targeted cancer cells while minimizing radiation dose to nearby normal cells. By considering these agents to be drugs from the outset, NCI contends that radiopharmaceuticals follow an easier programmatic path for development to address unmet medical needs. The NCI has published a series of white papers outlining its position on several key trial issues. More details can be found by clicking on the white paper links below.
