Evidence Hub

A Phase 1, Open-Label, Two-Cohort Study to Assess the Effect of a Strong CYP3A4 Inducer on the Pharmacokinetics of Atumelnant and the Effect of Atumelnant on the Pharmacokinetics of CYP3A4, P-gp, and MATE1/2-K Substrates in Healthy Participants

ClinicalTrials.gov · COMPLETED, 2026

46 participants

Abstract

This study aims to evaluate the impact of strong CYP3A4 induction on the pharmacokinetics (PK) of atumelnant, as well as the effect of atumelnant on CYP3A4, P-gp, and MATE1/2-K substrates in healthy participants.

Conditions: Healthy Volunteers.

Primary outcome: Cohort 1: Pharmacokinetics (AUC 0-last); Cohort 1: Pharmacokinetics (AUC 0-inf); Cohort 1: Pharmacokinetics (Cmax); Cohort 2: Pharmacokinetics (AUC 0-last); Cohort 2: Pharmacokinetics (AUC 0-inf); Cohort 2: Pharmacokinetics (Cmax).

Enrollment: 46 participants.

How strong is the evidence?

Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 46 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
