Phase II Safety and Acceptability of an Investigational Injectable Product, TMC278LA, for Pre-Exposure Prophylaxis

Rilpivirine (TMC278), a non-nucleoside reverse transcriptase inhibitor (NNRTI) is a substituted diaryl-pyrimidine (DAPY) derivative with potent antiviral activity against HIV. It is approved by the US FDA for once daily oral administration and is effective as part of treatment for ARV-na'ive HIV-infected patients as rilpivirine 25 mg capsules. It is also co-formulated with TDF and FTC for use as a once- daily single fixed-dose combination (Complera™).

Participants randomized to the placebo arm will receive oral placebo capsules prior to injection of saline solution (0.9%NaCI). Participants will be observed while taking the study product by site staff on approximately six occasions during the first two weeks of the oral run-in at Week 0 (Enrollment), at Week 2 (Oral Run-in Safety Visit), and on four separate DOT visits between Weeks 0 and 2. Cervicovaginal and rectal fluid will be collected for PK studies at a single follow-up visit.
