About this study

Multidrug resistant tuberculosis (MDR-TB) is difficult to treat and raises a great challenge to TB control program. That pyrazinamide can shorten the course of treatment and facilitate bacilli clearance has been proved recently. In 2011, WHO recommended to use pyrazinamide throughout the course of treatment for MDR-TB. However, pyrazinamide susceptibility testing has not been widely used in clinic. And the conventional testing is time-consuming and unreliable. In contrast, the detection of pncA and rpsA mutations with molecular methods can provide rapid results of pyrazinamide susceptibility. The purpose of this study is to evaluate the efficacy of the introduce the molecular testing of pyrazinamide susceptibility in optimizing the MDR-TB treatment regimen.

Read the detailed description

This is a phase 3, open labeled, prospective cohort study to evaluate the molecular testing of pyrazinamide susceptibility in optimizing the MDR-TB treatment regimen. Approximately 100 participants will be given the molecular detection of pncA and rpsA mutations and divide into to the pyrazinamide sensitive comparator group and the pyrazinamide resistant group based on the susceptibility results. For the pyrazinamide sensitive group, the regimen contains six months of chemotherapy with pyrazinamide, amikacin, levofloxacin, plus prothionamide, followed by six months of pyrazinamide, levofloxacin, clarithromycin, plus prothionamide. For the pyrazinamide resistant group, the regimen contains six months of chemotherapy with isoniazid, amikacin, levofloxacin, plus prothionamide, followed by eighteen months of isoniazid, levofloxacin, clarithromycin, plus prothionamide.

The participants will be followed up to 24 months after the start of the treatment. The primary outcome is the sputum culture conversion and the adverse events. Safety evaluations that will be performed are the routine lab tests, blood glucose, hearing , vital signs, ECG, reporting of adverse events, physical examinations and X-rays.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Median Time to Sputum Culture Conversion

    Measured: 24 months

Secondary outcomes (1)
  1. The Percentage of treatment success

    Treatment success is defined as:

    1. During the last 12 months of treatment,participants have at least 5 sputum cultures negative taken at least 30 days apart.
    2. During the last 12 months of treatment,participants have only one sputum culture positive, followed by at least 3 consecutive sputum cultures negative taken at least 30 days apart, without symptoms progression.
    3. Participants complete the treatment, but less than 5 culture results are available.

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Pyrazinamide containing regimen and Regimen without Pyrazinamide in people with Multidrug Resistant Tuberculosis, run by Huashan Hospital at 11 sites in China.

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 8 inclusion and 14 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 23 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in China. 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?

Contact Wenhong Zhang, PhD,MD (+86 21 52889999 ext. 8123, zhangwenhong@fudan.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Median Time to Sputum Culture Conversion (time frame: 24 months). 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 23 Apr 2014.
