|HIV Prevention HIV Infections||Drug: Raltegravir||Phase 4|
This is a single site, 72-week, prospective, open-label, non-randomized trial. One hundred and 50 (150) eligible participants will be assigned to receive RAL 400 mg BID along with tenofovir disoproxil fumarate/emtricitabine (TVD) 1 tablet once daily (3-drug NPEP) for 28-days or TVD 1 tablet once daily (2-drug NPEP) for 28-days according to established Australian guidelines for the use of 3 or 2-drug NPEP following a potential or actual sexual exposure to HIV in men who have sex with men (MSM).1 Based on hospital NPEP data over the past 2 years, it is anticipated that 100 MSM will receive 3-drug (RAL-TVD) NPEP and 50 will receive 2-drug (TVD) NPEP. Follow-up post NPEP is for 23 weeks i.e. to week 24 post exposure.
Primary study objectives:
To describe the safety of 28 days of nonoccupational post-exposure prophylaxis(NPEP) containing raltegravir (RAL) To describe the tolerability of 28 days of NPEP containing RAL To describe on-drug adherence and regimen completion rates of 28 days of NPEP containing RAL
Secondary study objectives:
To investigate whether or not receipt of NPEP decreases, increases or has no impact on HIV risk taking behaviour To describe the effects of RAL and tenofovir disoproxil fumarate/emtricitabine (TVD) on key inflammatory biomarkers in a subset of the main study population

- To describe the safety of 28 days of nonoccupational post-exposure prophylaxis containing raltegravir [ Time Frame: 28 days on drug with 5 month follow-up ]Objective AE and SAE data collection/grading utilising DAIDS data collection tool. Measurement of weight and vital signs, electrolytes, urea, creatinine, eGFR, inorganic phosphate, calcium, liver function, glucose, amylase, lipase, creatine kinase, lactate, urinalysis
- To describe the tolerability of 28 days of NPEP containing raltegravir [ Time Frame: 28 days on-drug and 5 months follow-up ]Subjective reporting of AEs with data collection/grading utilising DAIDS-AE
- To describe on-drug adherence and regimen completion rates of 28 days of NPEP containing raltegravir [ Time Frame: 28 days ]Adherence measurement by self report and pill count at 3 time points during the 28-days of NPEP
- To describe the context of the risk [ Time Frame: Baseline visit day 1 of NPEP ]Context of risk event described using directed questioning around pre determined variables
- To investigate whether or not receipt of NPEP decreases, increases or has no impact on future HIV risk taking behaviour [ Time Frame: Visit 2 (day 3-5 of study), visit 7 (day 82-84 of study) visit 9 (day 166-168 of study) ]Baseline data collection of HIV risk behaviour in 6 months preceeding NPEP. Repeat data collection at week 12 and week 24 post NPEP risk event. Data collected utilising assisted completion of HIV related behaviour questionaire.
- To describe the effects of raltegravir and truvada on key inflammatory biomarkers [ Time Frame: Day 1 and day 28 of NPEP ]Measurement of CR-P, D-Dimer, IL-6 on a subset of 50 patients receiving raltegravir/truvada NPEP and a subset of 25 patients receiving truvada alone as NPEP.
