Interventions
BEHAVIORAL
Comprehensive Tele-harm Reduction
Comprehensive Tele-Harm Reduction is on-demand services including low-barrier access to PrEP, medications for substance use disorder and hepatitis C treatment. It includes mobile phlebotomy, peer harm reduction counseling, medication management, telehealth mental health/substance use disorder services-- all delivered via an syringe services program.
BEHAVIORAL
Off-site Linkage to HIV Prevention
The community engagement team is comprised of peers and social workers and provides the wraparound support needed.The team will assist participants in scheduling appointments at community health clinics. The community engagement team provides active clinic referral- that is, a member of the team will accompany patients to the first clinic visit.
Primary outcome measures
HIV prevention via pre-exposure prophylaxis (PrEP)
Time frame: up to 12 months
Intracellular levels of tenofovir diphosphate (TFV-DP) by DBS or cabotegravir injection in previous 8 weeks or lenacapavir injection in previous 6 months by electronic health record abstraction
HIV prevention via medications for opioid use disorder
Time frame: up to 12 months
Buprenorphine/norbuprenorphine or methadone on urine drug screen; or naltrexone or buprenorphine extended-release injection in previous 4 weeks by electronic health record abstraction

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
