简要总结
Subjects preliminarily eligible who choose to receive PrEP will be included after obtaining the informed consent and confirmation of eligibility within 45 days after the screening visit.
Once included, participants will be examined in a follow-up visit performed four weeks later and evaluated for evidence of seroconversion to HIV, medication compliance and clinical toxicity. The second follow-up visit will occur at 12th week and every 12 weeks successively (quarterly). Quarterly visits include HIV testing, serum creatinine and counseling on medication compliance and risk reduction.
The study has a total of 6 visits plus 2 extra visits for those participants enrolled in the PK study. In all visits will be assessed the risks, HIV testing will be performed, monitoring of renal function and dispensing of the drug Truvada [emtricitabine 1 tablet (FTC) / tenofovir (TDF) (200/300 mg) once a day orally for 12 months].
Participants who have completed 48 weeks of follow-up or prematurely discontinue a PrEP will be encouraged to return for a follow-up visit after discontinuation of medication for monitoring of the status and evaluation of HIV as the resolution of side effects.
