Phase 1
Completed
Conditions
Human Immunodeficiency Virus Type 1
Interventions
Registration Number
NCT02547870
Lead Sponsor
Janssen Infectious Diseases BVBA
Brief Summary

The purpose of this study is to compare the single-dose pharmacokinetics of rilpivirine (RPV) after intramuscular (IM) injection of rilpivirine long-acting parenteral formulation (RPV-LA) and 'aged' RPV-LA, in healthy adult participants.

Detailed Description

This is a phase 1 randomized (study medication is assigned by chance), open-label (all people know the identity of the intervention), parallel-group, sequential study in healthy adult participants to investigate the effect of different storage conditions for RPV-LA on the single-dose pharmacokinetics of rilpivirine (RPV) after intramuscular injection. A total of 60 healthy adult participants will be enrolled in this study. The study will consist of 2 treatment sessions in a fixed sequential order : session 1 of up to day 8, all participants will receive a single oral dose of rilpivirine 25 milligram (mg) tablet on day 1, session 2 will consists of 2 treatment groups. The participants will be randomized in session 2 on Day 1 in a 1:1 ratio to Treatments A and B. Each treatment group will receive one IM injection of RPV LA on Day 1 of session 2. Session 1 and 2 will be separated by a washout period of at least 14 days. The total study duration for each participant will be approximately 6.5 months. Safety will be monitored throughout the study.

Area Under the Plasma Concentration-Time Curve From Time Zero to Last Quantifiable Time (AUC [0-last])In session1: Pre-dose, 0.5, 1, 2, 3, 4, 5, 6, 9, 12, 16, 24, 48, 72, 120 and 168 hours post-dose; In session 2: Pre-dose, 1, 2, 4, 8, 12, 24, 48, 72, 96, 120, 168,216, 264, 336, 408, 528, 672, 1344, 2016, 2688, 3360 and 4032 hours post-dose

The AUC (0-last) is the area under the plasma concentration-time curve for rilpivirine from time zero to last quantifiable time.

Maximum Observed Plasma Concentration (Cmax)In session1: Pre-dose, 0.5, 1, 2, 3, 4, 5, 6, 9, 12, 16, 24, 48, 72, 120 and 168 hours post-dose; In session 2: Pre-dose, 1, 2, 4, 8, 12, 24, 48, 72, 96, 120, 168,216, 264, 336, 408, 528, 672, 1344, 2016, 2688, 3360 and 4032 hours post-dose
