A Pilot Study on Raltegravir, Tenofovir and Emtricitabine for Peri-exposure Prophylaxis for HIV Infection

NCT01697046 · Status: UNKNOWN · Phase: PHASE3 · Type: INTERVENTIONAL · Enrollment: 65

Summary

This will be a pilot, open label study involving 65 participants. All participants will be followed until seroconversion or until the last enrolled participant completes one year of follow-up, whichever happens first. Participant study number will be given at the screening visit, prior to inclusion in the study.

The chosen intervention and study regimen are based on the dynamics of viral infection and the pharmacokinetics of the study drugs. In order to inhibit reverse transcription nucleoside and nucleotide analogues need to be phosphorylated intracellularly. On the other hand, available data indicate that it takes approximately 10 hours between exposure and HIV viral integration, offering a window of opportunity for Raltegravir to block integration and thus prevent infection, given that this drug does not need to be metabolized to exert its effect. The intervention will be maintained for 4 weeks following exposure, in accordance with Brazilian and CDC guidelines for PEP.

Conditions

Interventions

DRUG

Truvada and Isentress

Subjects with reported high-risk behavior (and anticipated future high-risk behavior) but no exposure in the immediate past will be the focus of this study. Participants will be prescribed raltegravir 400 mg BID + Truvada once daily. All study participants will receive a 4-days starter pack. Study participants will be instructed to start study drugs if they expect or experience an exposure of any mucous membrane (oral, urethral, anal) to semen. Subjects who expect or experience these exposures will be instructed to take 1 pill of Raltegravir 400mg and one pill of truvada, followed by a second dose of Raltegravir 12 hours later. From the second day onward, participants will be instructed to take Raltegravir 400 mg BID + Truvada once daily. The first dose should be taken no more than 6 hours before or 6 hours after the expected or actual exposure and continued for 28 days.
