The objective of this study is to compare and evaluate two strategies of delivering PrEP and Hepatitis C Virus (HCV) treatment to people who inject drugs to determine the best method of providing care. Participants will be randomized to one of two treatment arms: on-site integrated care or off-site referral to specialized care.
The first strategy, the on-site integrated care model, provides opioid agonist therapy (OAT) clinics and harm reduction sites/syringe access programs (SAP) with the tools to offer HIV prevention and HCV treatment on-site. The second strategy, the off-site referrals to specialized care model, connects people who are at risk for contracting HIV with patient navigators who help them access available HIV prevention care and, if necessary, HCV treatment.

Patient navigation will provided by trained patient navigators to participants randomized to the off-site referral to specialized care arm. Patient Navigators will actively coordinate and link participants to available clinics and community resources by scheduling appointments, arranging transportation, and assisting the participant with completing any paperwork that a clinic or service agent may require. The intervention will include up to five, 30-45 minute face-to-face meetings between the patient navigator and participant. These meetings will be tailored around each participant's needs. Additionally, the patient navigator assists the participant in identifying and utilizing informal and formal sources of support to move along the PrEP and/or HCV care continuum.The patient navigator will help the participant inform off-site physicians of the trial and of the availability of PrEP and HCV medication, should the physician and patient decide to initiate one or both treatments.
Counseling for PrEP initiation and adherence and, if necessary, HCV treatment will be provided by the clinical counseling staff of the on-site integrated care arm. Adherence counseling will include, but not be limited to, the indications, advantages, and disadvantages (e.g. side effects) of PrEP and HCV treatment in order to help the participant with his/her decision. The counselor will provide any necessary information to the participants and help them to address health and social needs. If required, the counselor will help the patient and physician with insurance-related issues. Adherence counselling will be carried out in a motivational style. The intervention will include five 30-45 minute face-to-face meetings with the participant and the adherence counselor over 6 months.

Sustained PrEP adherence
Average proportion of Dried Blood Spots (DBS) with detectable levels of Tenofovir at 6 months
Time frame: 6 months post randomization
HCV cure among HCV positive strata
HCV cure among the HCV positive strata will be compared between both treatment arms at 12 months post randomization. HCV cure is defined as initiating HCV treatment within six (6) months of being randomized and achieving sustained viral response 12 weeks (SVR-12) post-treatment completion. HCV treatment initiation will be measured using self-report and by assessing medical/drug dispensation records. SVR-12 will be measured by testing HCV-RNA negative 12 weeks after end of HCV treatment. If a participant initiates treatment within six (6) months of randomization but does not achieve SVR-12, they will not be counted as a success. Likewise, if a participant who is randomized as HCV positive achieves SVR-12 but did not initiate treatment within 6-months of randomization, they will not be counted as a success.
Time frame: 6-months post treatment initiation
Long-term sustained PrEP Adherence
Proportion of participants who self-report PrEP use and achieve detectable levels of tenofovir as measured by DBS testing at 6 months and 12 months post randomization.
Time frame: Up to 12 months
Behavioral disinhibition
Proportion of participants who increase sexual or injection risk behaviors as measured by self- report questionnaires administered at each research visit.
Time frame: Up to 12 months
STI or HIV incidence
Sexually Transmitted Infections (STI) incidence will be defined as a positive test result for Neisseria gonorrhoeae, Chlamydia trachomatis, HIV or syphilis in participants who formerly tested negative for the STI(s).

Time frame: Up to 12 months
HCV Incidence
HCV status will be determined by HCV-Ab testing, and if positive, HCV-RNA testing. New incidence of HCV will be defined as an HCV-Ab positive test results in participants who were HCV-Ab negative at a previous testing visit and HCV-Ab positive/HCV-RNA positive test results in participants who had previously tested HCV-Ab positive/HCV-RNA negative
Time frame: Up to 12 months
PrEP Initiation/Uptake
Proportion of participants who initiate PrEP before 6 months post randomization and between 6 to 12 months post randomization. PrEP initiation will be defined as record of dispensation of the first dose of TDF/FTC to a participant.
Time frame: Up to 12 months
