TMC649128HPC1001 - First In-human Trial to Examine Safety, Tolerability, and Pharmacokinetics (How the Drug is Absorbed Into the Bloodstream) of Increasing Single Oral Doses of TMC649128 in Healthy Volunteers

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the pharmacokinetics, safety, and tolerability of single oral doses of TMC649128 in healthy volunteers. Pharmacokinetics (PK) means how the drug is absorbed into the bloodstream, distributed in the body, and eliminated from the body.

Detailed Description
-----------------
TMC649128 will be investigated for the treatment of chronic hepatitis C infection. This is a Phase I, first in humans (no clinical studies have been performed to date), double-blind (neither the participant nor investigator knows whether they receive active or placebo), randomized (study medication is assigned by chance), placebo-controlled study to examine the safety, tolerability, and blood and plasma pharmacokinetics of increasing single oral doses of TMC649128. The single dose escalation will consist of 6 sessions (Sessions I to IV) in 6 panels (Panels 1 to 6) of 9 healthy adult volunteers each. The dose of TMC649128 will be consecutively escalated. In each session, 6 participants will receive TMC649128 and 3 participants will receive placebo, all with standard meals. Each session will have a staggered approach, ie, the first 4 participants will be dosed, followed by at least a 72-hour safety review and if no acute effects are observed, the remaining 5 participants will be dosed. The main focus of the trial is the determination of safety and tolerability of TMC649128 after single oral doses in fed conditions in healthy volunteers, but also the determination of the pharmacokinetic characteristics (level-profile of TMC649128 over time in the blood stream and urine). This evaluation requires multiple blood samples from Day 1 to Day 4. Safety assessments (blood and urine tests, blood pressure, pulse, electrocardiogram, and physical examination) will follow a different schedule and will be performed during each session, up to 4 weeks after the last administration. Safety and tolerability evaluations will be recorded at regular intervals throughout the trial. The single dose escalation will consist of 6 sessions in 6 panels of 9 healthy adult volunteers each. The dose of TMC649128 will be consecutively escalated.
