CCTG

The California Collaborative Treatment Group (CCTG) is a clinical trials consortium of academic institutions and community-based organizations in Southern California.


Since 1986, the CCTG has conducted high-impact, multi-center, investigator-initiated clinical trials focusing on:
  • HIV treatment and management
  • Risk reduction behavioral interventions
  • Pre-Exposure Prophylaxis (PrEP)
  • The CCTG research team includes clinicians, psychologists, behavioral scientists, biostatisticians, and pharmacology experts.
The CCTG Administrative Core is located at the UCSD AVRC. Collaborators include:

Current funding for the CCTG is provided by the California HIV/AIDS Research Program (CHRP) and backed by the California State Legislature. CHRP fosters outstanding and innovative research that responds to the needs of all people of California, especially those who are often underserved, by accelerating progress in prevention, education, care, treatment, and a cure for HIV/AIDS.

Community members interested in participating in a CCTG study should contact the Screening Coordinator at (619) 543-8080.
