About this study

Official title: Randomized, Double-Blind, Placebo-Controlled Three-Part Phase 1 Study of Safety, Tolerability, Pharmacokinetics, and Food Effect of MRX-4 Administered Orally to Healthy Volunteers in Single and Multiple Ascending Dose Cohorts to Evaluate Drug Interactions With Omeprazole

A phase one study of the safety, tolerability, and pharmacokinetics of a new oxazolidinone antibiotic. Cohorts of healthy adults (female and male) will participate in:

single dose escalation study of increasing doses of MRX-4 given by mouth others will participate in multiple dose escalation cohorts of MRX-4 given twice daily by mouth.

other cohorts of subjects will participate in the study to evaluate the impact of concomitant food or Omeprazole on safety, tolerability and pharmacokinetics of MRX-4

What is being measured

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

  1. Safety of single and multiple ascending doses of MRX-4

    Summary of number of subjects with changes in vital signs, physical examinations, clinical lab data, ECG parameters and adverse events

    Measured: Screening through end of study visit on Day 7 (Part 1), Day 17 (Part II) and Day 14 (Part III)

  2. Summary of concentration time data for MRX-4 and its metabolites

    Concentration time data for MRX-4 and its metabolites in blood and urine

    Measured: Pre-dose through 72 hours post dose

Secondary outcomes (3)
  1. Summary of the plasma concentration teim data for MRX-4 under fed or fasted conditions

    Concentration time data for MRX-4 and its metabolites in blood and urine under fed and fasted conditions

    Measured: Pre-dose through 72 hours post dose

  2. Safety of MRX-4 co-administered with omeprazole

    Summary of the number of subjects with changes in vital signs, physical examinations, clinical lab data, ecg parameters and adverse events

    Measured: Screening through end of study on Day 14

  3. Summary of the plasma concentration time data for MRX-4 co-administered with omeprazole

    Concentation time data for MRX-4 and its metabolites in blood and urine with and without omeprazole

    Measured: Pre-dose through 72 hours post dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Oral single doses of MRX-4, Oral multiple doses of MRX-4 and MRX-4 co-administered with omeprazole in people with Safety, run by MicuRx.

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 1 inclusion and 1 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 9 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Safety of single and multiple ascending doses of MRX-4 (time frame: Screening through end of study visit on Day 7 (Part 1), Day 17 (Part II) and Day 14 (Part III)). 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 9 Nov 2023.
