PRe-Exposure Prophylaxis Acceptability & Readiness Assessments for Toronto gaY, Bisexual and Other Men Who Have Sex With Men-5

Phase 4
Completed
Conditions
HIV
Human Immunodeficiency Virus
Interventions
Drug: Tenofovir/emtricitabine
Registration Number
NCT02149888
Lead Sponsor
Unity Health Toronto
Brief Summary

Canada continues to see an unrelenting stream of new HIV diagnoses, with a disproportionate burden among gay, bisexual, and other MSM in major centers such as Toronto. Pre-exposure prophylaxis (PrEP) with oral, daily tenofovir/emtricitabine (TDF/FTC, Truvada®) is a novel biomedical approach to HIV prevention shown in the iPrEx trial to be safe and efficacious in reducing HIV acquisition by 44% among MSM, when provided in a comprehensive package of HIV prevention interventions including counseling, testing/treatment of sexually transmitted infections (STIs), and condoms. There is now widespread mobilization to assess the feasibility of PrEP roll-out worldwide, with urgent calls for 'demonstration projects' addressing real-world PrEP implementation issues.

PREPARATORY-5 is Canada's first PrEP demonstration project, and will examine real-world PrEP implementation issues including acceptability, effectiveness, impact on sexually transmitted infections, and strategies for supporting adherence outside the clinical trial setting. The investigators have also established a comprehensive community-based research program investigating the role of community-based organizations in PrEP implementation and delivery.

Primary Outcome Measures
NameTimeMethod
Participants' self-reported overall acceptability of PrEP12 months

Participants' self-reported overall acceptability of PrEP over the full one-year follow-up period (including the use of the medication, clinic visits, and their impact on the participant's life) will be quantified using a Likert scale.

The level of community interest in PrEP12 months

The level of community interest in PrEP will be measured by quantifying the volume, rate and HIV risk levels of patient referrals to the PrEP clinic from each key referral source

Secondary Outcome Measures
NameTimeMethod
Sexually transmitted infections12 months

Testing will be performed at each study visit to screen for gonorrhea, chlamydia and syphilis infection, including pharyngeal swab cultures, rectal swab cultures and urine NAAT tests.

Adherence to daily TDF/FTC-based PrEP12 months

Adherence will be measured by self-report, pill count, and intra-RBC tenofovir diphosphate levels.

Time required by the patient, physician and research coordinator for each type of study visit.12 months

The time required by the patient, physician and research coordinator will be measured for each type of study visit.

Percentage change in bone mineral density at the lumbar spine and total hip12 months
HIV infection12 months

HIV infection will be detected using point-of-care tests, standard serology and HIV RNA testing.

Burden of syndemic health problems12 months

The burden of specific syndemic health problems (depression, social anxiety, substance abuse, sexual addiction, childhood sexual abuse, partner violence) will be quantified using standardized, validated psychometric tools.

Pilot testing study instruments12 months

Outcomes related to pilot testing study instruments will include numbers of minutes required and participant-reported acceptability for each procedure

Change in estimated glomerular filtration rate12 months

Estimated by the Modified Diet in Renal Disease (MDRD) formula

Adverse events12 months

Adverse events will be assessed at each visit via clinical assessment and laboratory monitoring (CBC, phosphate, urinalysis).
