ANCHOR: Hepatitis C Treatment to Prevent HIV, Initiate Opioid Substitution Therapy, and Reduce Risky Behavior
Study Details
Study Description
Brief Summary
This is an open label, non-randomized, observational pilot study to evaluate a model of care for treatment of hepatitis C in people with ongoing injection drug use. Participants will be treated with direct-acting antivirals (DAA) as per standard of care and will concomittantly be offered pre-exposure prophylaxis for HIV prevention and buprenorphine for treatment of opioid use disorder when clinically indicated.

Detailed Description
Hepatitis C (HCV) is a chronic infection with significant morbidity and mortality. The development of directly acting antivirals (DAA) has dramatically improved the cure rate of HCV treatment. However, despite the availability of effective therapy, the global epidemic of HCV infection continues to be driven by people with ongoing injection drug use (PWID), who are largely excluded from HCV therapy. Several critical barriers exist preventing high-risk patients' entry to care, including (1) lack of engagement in the traditional healthcare system by marginalized patient populations, and (2) insurance restrictions due to concerns regarding treatment adherence and HCV reinfection. Furthermore, ongoing injection drug use places these individuals at high risk of HIV acquisition. However, studies have repeatedly demonstrated that pre-exposure prophylaxis (PrEP) reduces HIV acquisition and opioid substitution therapy with buprenorphine reduces HIV and HCV acquisition in PWID.
As such, we propose a comprehensive model of care to engage individuals with ongoing injection drug use in treatment of HCV, in conjunction with collocated services to prevent HIV acquisition and HCV reinfection, including pre-exposure prophylaxis and opioid substitution therapy. This pilot trial will demonstrate whether a comprehensive model of care can simultaneously treat HCV, and prevent HCV reinfection, HIV acquisition and effectively treat opioid use disorder.
