Clinical Research Grants Branch (CRGB)

What We Do:

The CRGB plans and supports extramural research grants to test medications for the treatment of drug abuse and dependence disorders in several key areas: controlled compound assessment clinical pharmacology studies, controlled clinical trials for new treatment agents or new indications for marketed medications and clinical studies of the pharmacological effects and interactions among experimental addiction medications and medications for associated medical conditions and psychotherapeutic agents. The Branch also supports experimental pharmacotherapy studies to enhance the efficacy of approved marketed medications, and experimental pharmacotherapy studies of psychotropic or other medications used in the treatment of mental disorders in drug dependent individuals including drug-induced or drug-related mental disorders. CRGB staff members provide technical assistance to grantees, contractors, and applicants. The CRGB provides guidance is given to investigators and manages the administrative aspects of DTMC's research and development contract portfolio.
