NCT07550621

Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

  • Cmax of MDR-001

    Maximum observed plasma concentration of MDR-001 after single-dose administration alone and in combination with rifampin (Part A) or itraconazole (Part B).

    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).

  • AUC0-t of MDR-001

    Area under the plasma concentration-time curve from time zero to the last measurable concentration after single-dose administration alone and in combination.

  • AUC0-∞ of MDR-001

    Area under the plasma concentration-time curve from time zero extrapolated to infinity after single-dose administration alone and in combinatio

Intervention Model
CROSSOVER
Model Details: Fixed-sequence crossover design where each participant serves as their own control. The study consists of two independent, non-randomized, open-label parts: Part A and B. The design allows within-participant comparison of pharmacokinetic parameters (alone vs. combination) for each part independently.
