Since the existed anti-HIV compound efavirenz showed a serious of side effects including low genetic barrier to resistanc Janssen R&D Ireland has signed a licensing agreement with PATH for the early development of a long-acting depot formulation of the human immunodeficiency virus type 1 (HIV-1) drug rilpivirine. The study consists of 3 phases; a screening phase up to 27 days (Day -28 to Day -2), an in-patient phase from Day -1 to Day 3 (dosing day is Day 1), and a follow-up assessment phase from Day 4 to the last follow-up assessment scheduled on Day 15 or at the time of early withdrawal. Background: The recently approved anti-AIDS drug rilpivirine (TMC278, Edurant) is a nonnucleoside inhibitor (NNRTI) that binds to reverse transcriptase (RT) and allosterically blocks the chemical step of DNA synthesis. Rilpivirine has a half-life of 50 hours and is metabolized by CYP3A4-mediated hepatic oxidation; no inhibition or induction of cytochrome P-450 isoenzymes has been reported. Binding of an NNRTI causes structural changes that perturb the alignment of the primer terminus and polymerase active site, preventing viral DNA synthesis. Currently, recommended cART for HIV-1 treatment is a three-drug combination, whereas the pre-exposure prophylaxis (PrEP) regimens consist of one or two antivirals. A liquid chromatographic method with UV detection was developed for the assay of a tablet for HIV (human immunodeficiency virus) treatment containing three active components, which are emtricitabine, tenofovir disoproxil fumarate and rilpivirine. Rilpivirine is an antiretroviral agent belonging to the diarylpyrimidine subclass of NNRTIs, also referred to as “next-generation” or “second-generation” HIV-1 NNRTIs. This is a single center, open-label, single oral dose study in healthy Japanese adult male participants. , 213 ( 2016 ) , pp. required for DNA synthesis (2–4), although some new highly potent experimental NRTIs retain a 3-OH and inhibit RT by blocking translocation or by delayed chain termination (5, 6).
