Brief Summary:
Evaluation of effect of rifampin or rifabutin on single dose PK of TMC207 in healthy volunteers

Condition or disease Intervention/treatment Phase
Tuberculosis Drug: Rifabutin Drug: Rifampin Drug: TMC207 Phase 1

Detailed Description:
32 (16 per treatment group) healthy male or female subjects, 18 - 45 years old will be enrolled.Subjects will receive two single oral doses of 400mg TMC207, first on Study Day 1 followed by a 28-day wash-out, the second on Study Day 29. On Study Day 28, any abnormal safety labs will be reviewed by study physician and be determined not to meet the exclusion criteria before administration of the second dose of TMC207. Rifabutin 300mg (Group 1) or rifampin 600mg (Group 2) will be administered once daily during Period 2 from Study Day 20 through Study Day 41. The primary endpoint for the study (pharmacokinetics, safety and tolerability of TMC207 (and its M2 metabolite) will be determined on the final study visit, Day 57 (28 days after the last TMC207 dose in Period 2).

Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

-Aged between 18 and 45 years, extremes included. -Non tobacco/nicotine using (at least 3 months prior to screening). -Body Mass Index (BMI, weight in kg divided by the square of height in meters) of 18.0 to <35.0 kg/m^2 -Informed Consent Form (ICF) signed voluntarily before the first trial-related activity. -Able to comply with protocol requirements. -Healthy on the basis of a medical evaluation or history that reveals the absence of any clinically relevant abnormality and includes a physical examination, medical history, electrocardiogram (ECG), vital signs, ophthalmologic exam, the results of blood biochemistry, and hematology tests, and a urinalysis carried out at screening (See Section 7.2). -Subjects will be enrolled in this study only if they have undergone vasectomy/complete hysterectomy, tubal ligation, or other sterilizing procedure, or the subject is a post-menopausal woman for more than two years, or if sexually active subjects agree to use two of the following forms of adequate contraception during the study and for 12 weeks after the final dose: abstinence, condoms with or without spermicide gel, diaphragm with spermicide gel, hormonal or non-hormonal intrauterine device, oral contraceptive pills, and depot progesterone injections. If a subject is usually not sexually active but becomes active, the subject and his or her partner must use two of the listed contraceptive methods.

Exclusion Criteria:

Medical History -History or evidence of current use of alcohol, barbiturate, amphetamine, recreational, or narcotic drug use, which in the investigator's opinion would compromise subject's safety and/or compliance with the trial procedures. -Any clinically significant (as deemed by the Principal Investigator) history of acute illness (resolved within 4 weeks of screening), asthma, or presence of cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal (including eating disorders), endocrine, metabolic, immunologic, dermatologic, neurologic, psychological, or psychiatric disease. -Currently significant diarrhea, gastric stasis, or constipation that in the investigator's opinion could influence drug absorption or bioavailability. -Any history of significant skin disease such as, but not limited to, rash or eruptions, drug allergies, food allergy, dermatitis, eczema, psoriasis, or urticaria.
