A Study to Evaluate Safety, Acceptability, Pharmacokinetics, and ex Vivo Pharmacodynamics of TMC278 Long Acting Formulation in HIV-1 Seronegative Participants

The purpose of this study is to evaluate the safety, acceptability, pharmacokinetics (what the body does to the medication), and ex vivo (tested outside the body) pharmacodynamics (what the medication does to the body) of TMC278 long acting (slowly effective after initial dosage and maintaining its effects over a long period of time) when administered as an intramuscular (ie, in to the muscle) injection in adult participants who are seronegative for human immunodeficiency virus type 1 (HIV-1).
