About this study

Official title: Personalized Therapy Durations Defined by the Blood RNA-based Model for Individualizing Treatment in Multidrug-Resistant Tuberculosis

PredictEndTB signature is a non-inferiority, prospective, parallel-group open-label randomized controlled trial evaluating the efficacy of individualised antituberculous treatment durations that utilize the transcriptomic signature-based model compared to the standardised twenty months treatment in a cohort of multidrug-resistant tuberculosis patients.

Read the detailed description

This study is a non-inferiority, prospective, parallel-group open-label randomized controlled trial. Three hundred forty-two HIV-negative patients diagnosed with pulmonary tuberculosis (TB) and starting a new anti-multidrug-resistant tuberculosis (MDR-TB) treatment cycle will be included in the study. Two randomized arms of 171 patients each will be recruited over the two-year period, each patient will be followed-up over the entire course of anti-TB treatment and one year after the end of therapy. Regular study visits will include physical examination, collection of sputum, blood and urine and filling in the study questionnaire. On the collected specimens standard bacteriological and blood tests, as well as extended immunological analysis, will be performed. In the experimental group, an RNA transcriptomic analysis using RNA-Seq technology will also be performed.

In the control arm, the patients will receive a standardised World Health Organization recommended 20 months treatment while in the experimental arm the treatment duration will be guided by the transcriptomic signature-based model.

Treatment outcomes and level of TB relapse and survival within the follow-up period will be compared between the experimental and control arms. The efficacy of biomarker-guided treatment therapy will be assessed by a comparison of the proportions of favourable study outcome between two arms.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Individualised treatment duration based on RNA transcriptomic modelDiagnostic test

    Anti-MDR-TB treatment with standard drugs and individual treatment duration guided by the RNA transcriptomic model; may be shorter or longer than standard WHO-recommended treatment duration of 20 months.

What is being measured

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

  1. Proportion of patients with favourable study outcome 12 months after treatment end

    The non-inferiority of the experimental arm compared to the control arm will be established if in the Per-Protocol population the difference in proportions of patients with a favourable study outcome between study arms is greater than the lower equivalence margin of 12%. This outcome measure is assessed after up to 24 months of treatment (usually 20 months) plus 12 months of follow-up after the end of treatment.

    Measured: up to 36 months

Secondary outcomes (4)
  1. Proportion of patients who was lost to follow-up during treatment

    This outcome measure will be used in the secondary efficacy analysis in the Intention-to-Treat population

    Measured: up to 24 months

  2. Proportion of patients who had a treatment failure

    This outcome measure will be used in the secondary efficacy analysis in the Intention-to-Treat population

    Measured: up to 24 months

  3. Proportion of patients who died from TB

    This outcome measure will be used in the secondary efficacy analysis in the Intention-to-Treat population

    Measured: up to 36 months

  4. Proportion of patients who died of any cause

    This outcome measure will be used in the secondary efficacy analysis in the Intention-to-Treat population

    Measured: up to 36 months

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted5 Mar 2021
  2. Study start1 Apr 2021
  3. Primary completion1 Nov 2022
  4. Study completion1 Nov 2022

Why it stopped: Change in WHO recommendations for standard of care (control arm); availability of new shorter treatment regimens for MDR-TB; war in Ukraine where two study sites are located; key trial team members left the team.

Questions about this trial

What is this clinical trial studying?

A study testing Individualised treatment duration based on RNA transcriptomic model in people with Tuberculosis, Pulmonary and Tuberculosis, Multidrug-Resistant, run by Research Center Borstel at 5 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 6 inclusion and 6 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: stopped early, as of the sponsor's last update on 13 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Ukraine, Germany, Moldova, Romania. 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.

Are results available for this study?

The study was stopped early (reason given: Change in WHO recommendations for standard of care (control arm); availability of new shorter treatment regimens for MDR-TB; war in Ukraine where two study sites are located; key trial team members left the team.). 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?

Proportion of patients with favourable study outcome 12 months after treatment end (time frame: up to 36 months). 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 NCT04783727, 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 13 Dec 2023.
