PK Interaction Between Rifapentine or Rifampicin and a Single Dose of TMC207 in Healthy Subjects (TMC207-CL002)

Completed · Phase 1

Conditions studied: Tuberculosis

In brief

This is a open-label study, 2-treatment, 2-period, single sequence design. Period 1 will examine the pharmacokinetics of TMC207 in the absence of rifapentine or rifampicin. Subjects will receive a single 400-mg dose of TMC207 administered alone on Study Day 1. Period 2 will examine the effects of repeated doses of either rifapentine or rifampicin on TMC207 pharmacokinetics and will begin on Study Day 20. During Period 2, subjects will receive 22 daily doses of either 600 mg rifapentine or rifampicin from Study Day 20 through Study Day 41. A single 400-mg dose of TMC207 will be administered on Study Day 29. Subjects will be confined to the clinic from Study Day-1 to Study Day 2 in the morning of Period 1, and Study Day 19 to Study Day 30 in the morning of Period 2. The study hypothesis is to determine whether Rifapentine affects the pharmacokinetics of TMC207 as measured by effects on Cmax and AUC(0-t) to a lesser degree than rifampicin.

Who can join

Age: 19 and older, up to 55. Sex: any. Healthy volunteers: accepted.

You may qualify if…

Aged between 19 and 55 years, extremes included.

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, and the results of blood biochemistry, and hematology tests and a urinalysis carried out at screening (See Section 6.1).

You may not qualify if…

Female, except if postmenopausal since more than 2 years, or post-hysterectomy, or post surgical sterilization, i.e., tubal ligation (without reversal operation) or total hysterectomy.
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 Principle Investigator) history acute illness (resolved within 4 weeks of screening), 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. Subjects with a history of skin disease may be enrolled into the study after consultation with the Sponsor Medical Monitor.
Previously demonstrated clinically significant allergy or hypersensitivity to any of the excipients of the investigational medication administered in this trial (i.e. rifapentine, rifampicin, and TMC207).
Subjects with QTcF [Fredericia correction] interval > 450 msec (based on the average of the triplicate ECGs) at screening (and confirmed by repeat ECG).
Subjects with any other clinically significant ECG abnormality at screening, such as arrhythmia, ischemia, or evidence of heart failure or with a family history of Long QT Syndrome.
Use of concomitant medication, including over-the-counter products and dietary supplements, except for ibuprofen and paracetamol up to 7 days before the first dose of trial medication and all prescribed medication must have been discontinued at least 14 days before first intake of trial medication.
Participation in an investigational drug trial within 60 days prior to the first intake of trial medication.
Donation of blood or significant loss of blood within 56 days or plasma donation within 7 days preceding the first intake of trial medication.
Having received TMC207 in a previous trial.
Positive HIV-1 or HIV-2 test at screening
Hepatitis A, B, or C infection (confirmed by hepatitis A antibody IgM, hepatitis B surface antigen, or hepatitis C virus antibody, respectively) at screening.
A positive urine drug test at screening. Urine will be tested to check the current use of alcohol, amphetamines, benzodiazepines, cocaine, cannabinoids, and opioids.
Subjects with the following laboratory abnormalities at screening as defined by the NIH, NIAID, Division of Microbiology and Infectious Diseases (DMID) Adult Toxicity Table and in accordance with the normal ranges of the clinical laboratory: Serum creatinine grade 1 or greater (> 1.0 x ULN); Pancreatic lipase grade 1 or greater (> 1.0 x ULN); Hemoglobin grade 1 or greater (≤ 10.5 g/dL); Platelet count grade 1 or greater (≤ 99000/mm3); Absolute neutrophil count grade 1 or greater (≤ 1500/mm3); Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) grade 1 or greater (> 1.0 x ULN); Total bilirubin grade 1 or greater (> 1.0 x ULN); Any other toxicity grade 2 or above, including: proteinuria (spot urine) > 1+ and gross hematuria.
