About this study
Official title: Pharmacokinetic Interaction Study of Rifampicin, Isoniazid and Moxifloxacin in Tuberculosis Patients in Bandung, Indonesia
Pharmacokinetic study in TB patients to determine the effect of rifampicin on the pharmacokinetic profile of moxifloxacin.
Read the detailed description
Tuberculosis is an infectious disease that still causes many victims in the developing world, especially in Indonesia. Rifampicin, isoniazid and ethambutol are the cornerstone of the current treatment. The disadvantage of the current treatment is the long, six-months, duration of the treatment. This long duration contributes to suboptimal adherence to the TB drugs.Thus, there is a very urgent need to evaluate drugs that may help shortening TB treatment. The fluoroquinolone moxifloxacin has shown early bactericidal activity (EBA) in patients with pulmonary TB, and has shown rapid and reliable sterilization. Rifampicin is a strong inducer of the CYP enzymes, but it also induces phase II metabolism. As moxifloxacin is metabolized by phase II metabolism, rifampicin could cause a decrease in the plasma concentrations of moxifloxacin. Therefore, a pharmacokinetic interaction study is warranted.

Where is the study taking place?
The record lists 1 site in Indonesia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pharmacokinetic (24 hrs) curves will be drawn. The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00306319, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Nov 2020.
