About this study

Official title: Evaluation of the Efficacy and Safety of a Short-course, Daily, 4-month Regimen Including Isoniazid, Pyrazinamide, Rifapentine and Moxifloxacin (2HZPM/2HPM) for the Treatment of Drug-susceptible Pulmonary Tuberculosis in Taiwan (ESCAPE-TB)

The development of efficacious, safe, and shorter treatment regimens could significantly improve TB management and treatment success rates. This prospective, 3-year, single arm study is to evaluate the efficacy and safety of a short-course, 4-month regimen including isoniazid(H), pyrazinamide(P), rifapentine (P), and moxifloxacin(M) (2HZPM/2HPM) for the treatment of drug-susceptible, pulmonary tuberculosis, and compared with a historical control group receiving the standard six-month regimen.

Read the detailed description

Shorter regimens have the potential to impact on TB control by reducing TB incidence and mortality, and improve outcomes by increasing patient adherence to treatments and decreasing duration to cure, in addition to reducing costs to the health system and the patient. The purpose of this prospective, three year, single arm study is to evaluate whether a short course, four-month regimen containing rifapentine and moxifloxacin (2HZPM/2HPM) are as effective and/or as tolerable as the standard six-month regimen for the treatment of drug-susceptible, pulmonary tuberculosis (TB). A historical group receiving the standard six-month regimen is used as control at a ratio of 1:2. The pharmacokinetic and pharmacodynamic profile of rifapentine in Asian patients. Analysis of of histocompatibility leucocyte antigen (HLA) associations with adverse events and changes in biomarkers will be done.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 12 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Taiwan. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

TB disease free survival at 12 months (time frame: 12 months after study treatment assignment). 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?
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 Jul 2024.
