Clinical/Medical Branch (CMB)

What We Do:

The CMB plans, designs, and implements a comprehensive program that evaluates, in a clinical setting, investigational and marketed medications for their potential value in treating substance abuse disorders. Potential medications are studied in both inpatient and outpatient clinical settings and can be managed through all phases of clinical development (Phases 1-4). The CMB is comprised of clinicians, clinical trials specialists and a statistician. CMB staff design protocols, monitor clinical trials, analyze data, and provide consultation and collaboration to the pharmaceutical industry, academia, and other interested parties regarding projects of mutual interest, study design, and data analysis. In addition, the CMB supports research training of clinicians to expand expertise in clinical research in methods as applied to medications development. The CMB files INDs in collaboration with the Regulatory Affairs Branch.
