About this study

This trial aims to determine whether the addition of rosuvastatin to standard TB therapy in pulmonary tuberculosis results in accelerated of sputum culture conversion. The trial will also investigate potential new biomarkers of sterilising activity and immune-modulatory activity.

Read the detailed description

Rosuvastatin is an HMG Co-A reductase inhibitor which may be of value as possible adjunctive agents to standard TB therapy. Cell culture assays and animal models demonstrate that statins are bactericidal against Mtb with effects that are additive to that of anti-tuberculous therapy.

This is a Phase IIb randomised, controlled, open-label, early bactericidal activity trial. We will recruit patients between the ages of 18 and 75 with newly-diagnosed smear or Xpert positive pulmonary TB, who have had no more than 7 days of TB therapy.

Patients will be randomised to take either standard TB therapy or standard TB therapy plus rosuvastatin for the first 8 weeks of their therapy. After the first 8 weeks, patients will continue standard combination TB therapy and remain in trial follow-up until week 24. The trial will collect sputum for culture on a weekly basis for the first 8 weeks of the trial, and less frequently leading up to week 24.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Rosuvastatin 10mg, Rifampicin and Isoniazid in people with Pulmonary Tuberculosis, run by National University Hospital, Singapore at 6 sites in 4 countries.

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 9 inclusion and 27 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 7 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Philippines, Singapore, Uganda, Vietnam. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Gail Cross (+65 83280377, mdcgbc@nus.edu.sg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to culture conversion in Liquid Media (time frame: within 8 weeks after randomisation). 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 NCT04504851, which also lists 2 linked publications.

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 7 Aug 2020.
