About this study

Official title: A Phase IIB, Open-Label, Randomized Controlled Dose Ranging Multi-Center Trial to Evaluate the Safety, Tolerability, Pharmacokinetics and Exposure-Response Relationship of Different Doses of Sutezolid in Combination With Bedaquiline, Delamanid and Moxifloxacin in Adult Subjects With Newly Diagnosed, Uncomplicated, Smear-Positive, Drug-sensitive Pulmonary Tuberculosis

This study is an open-label, randomized, controlled, multi-center Phase IIB dose-finding trial to evaluate the safety, tolerability, pharmacokinetics and exposure-response-relationship of different doses of sutezolid (STZ) in combination with bedaquiline, delamanid and moxifloxacin in adults with newly diagnosed, uncomplicated, smear positive and drug sensitive pulmonary tuberculosis. Participants will be randomized to one of five arms containing bedaquiline, delamanid and moxifloxacin with different doses of STZ (0mg, 600mg once daily (OD), 1200mg OD, 600 mg twice daily (BD), 800 mg BD). Study treatment duration will be three months, followed by a follow-up period of 2 weeks.

The primary objective is to identify the optimal dose of sutezolid to be used in subsequent studies that provides the best efficacy at acceptable safety of the drug by describing the safety, tolerability and exposure toxicity relationship of sutezolid (and its main metabolite) given over three months, in combination with standard-dose bedaquiline, delamanid and moxifloxacin, compared to standard-dose bedaquiline, delamanid and moxifloxacin alone.

Read the detailed description

This open-label Phase IIB dose-finding, randomized, controlled study with a duration of three months of experimental therapy in adult patients with newly diagnosed, smear positive, uncomplicated, drug sensitive pulmonary tuberculosis (TB) will be carried out to evaluate the safety, efficacy, tolerability, pharmacokinetics and exposure/response-relationship of different doses of sutezolid in combination with bedaquiline, delamanid and moxifloxacin (BDM).

Participants will be randomized to one of five arms containing bedaquiline, delamanid and moxifloxacin with different doses of STZ (0mg, 600mg OD, 1200mg OD, 600 mg BD, 800 mg BD). Study treatment duration will be three month, followed by a follow-up period of 2 weeks.

A total of 75 male or female subjects, aged between 18 and 65 years with newly diagnosed, drug sensitive, uncomplicated, smear-positive, pulmonary TB will be included and randomized to one of five arms containing BDM with different doses of STZ:

  • Arm 1 (U0): Bedaquiline, delamanid, moxifloxacin
  • Arm 2 (U600): Bedaquiline, delamanid, moxifloxacin, sutezolid 600 mg OD
  • Arm 3 (U1200): Bedaquiline, delamanid, moxifloxacin, sutezolid 1200 mg OD
  • Arm 4 (U600BD): Bedaquiline, delamanid, moxifloxacin, sutezolid 600 mg BD
  • Arm 5 (U800BD): Bedaquiline, delamanid, moxifloxacin, sutezolid 800 mg BD

A sub-study will assess CYP P450 3A4 enzyme induction potential using the probe drug midazolam, given to participants in arm 5.

Using PK data and data from primary efficacy and safety objectives, we will develop an exposure-response and a population PK-model for sutezolid and its main metabolite to support the main objective, selection of a dose for subsequent studies.

What participants receive

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

  • SutezolidDrug

    Also called PNU-100480

    Sutezolid is not licensed yet. Current experience in humans up to Phase IIA. Dose according to randomization to dosing arms 2-5.

  • Bedaquiline, Delamanid, MoxifloxacinDrug

    Also called BDM

    These three licensed drugs form the backbone of a new regimen to which sutezolid is added in arms 2-5.

  • Midazolam oral solutionDrug

    Midazolam will be administered as per probe drug use in a single dose of 2 mg at day -1 and day 14 to assess the potential of sutezolid for CYP 459 3A4 enzyme induction, as measured by its influence on the ratio of AUCs of the CYP 3A4 probe drug

Model description
75 participants will be randomized to one of five arms (15 participants per arm) to receive study medication containing bedaquiline, delamanid, and moxifloxacin with different doses of sutezolid, ranging from 0mg sutezolid up to 800mg sutezolid twice a day. Participants will be randomised and stratified by site and HIV status. Participants will visit the study clinic on a weekly basis for sputum collection, safety monitoring and receipt of study medication. After the completion of three months of experimental treatment participants in the experimental arms will be handed over to government TB programmes to complete their course of anti-TB treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Sutezolid, Bedaquiline, Delamanid, Moxifloxacin and Midazolam oral solution in people with Pulmonary Tuberculosis and Other Specified Pulmonary Tuberculosis, run by Michael Hoelscher at 4 sites in 2 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 11 inclusion and 45 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: finished, as of the sponsor's last update on 1 May 2023. 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 Tanzania, South Africa. 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?

Primary Efficacy Endpoint: Change in sputum mycobacterial load over time (time frame: Days 01 - 84). 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 NCT03959566, 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 1 May 2023.
