About this study

Official title: A Phase 1 Study to Evaluate the Effect of Rifampin on the Pharmacokinetics of MDR-001 and the Effect of Itraconazole on the Pharmacokinetics of MDR-001 in Healthy Adult Study Participants

A Phase I, open-label, fixed-sequence, two-part drug-drug interaction study in healthy Chinese adults to evaluate the effect of multiple-dose rifampin (Part A) or itraconazole (Part B) on the single-dose pharmacokinetics of MDR-001, an oral GLP-1 receptor agonist.

Read the detailed description

This phase 1, single-center, open-label, fixed-sequence drug-drug interaction study will evaluate the effect of multiple-dose rifampicin (a strong CYP3A4 inducer) and multiple-dose itraconazole (a strong CYP3A4 inhibitor) on the single-dose pharmacokinetics of MDR-001, an oral small-molecule GLP-1 receptor agonist being developed for weight management. The study plans to enroll 28 healthy Chinese adults (18-55 years, BMI 18-28 kg/m²), with 12 participants in Part A (rifampicin) and 16 in Part B (itraconazole). The primary outcomes are the effects of rifampicin and itraconazole on Cmax, AUC0-t, and AUC0-∞ of MDR-001. Secondary outcomes include safety and tolerability (adverse events, vital signs, ECG, laboratory tests) and comparison of other pharmacokinetic parameters (Tmax, t1/2, MRT, CL/F, Vd/F, λz) between MDR-001 alone and combined with the interacting drugs.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MDR-001, Rifampin and Itraconazole in people with Healthy Volunteers (HV), run by MindRank AI Ltd at 1 site 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 6 inclusion and 25 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: opening soon, as of the sponsor's last update on 24 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Guodong Li, PhD (+8618968027256, guodong.li@mindrank.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cmax of MDR-001 (time frame: Baseline (Day 1 pre-dose) and up to 48 hours post-dose on Day 1 and on co-administration (Day 10 for Part A, Day 7 for Part B).). The study lists 3 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 24 Apr 2026.
