A Phase 1, Open-Label Evaluation of the Pharmacokinetics and Safety of a Single Dose of Apraglutide in Subjects With Normal and Impaired Hepatic Function

Phase 1

Completed

• Conditions: Hepatic Impairment
• Interventions: Drug: Apraglutide

• Registration Number: NCT05706623
• Lead Sponsor: VectivBio AG

Brief Summary

The primary objective is to assess the PK of apraglutide in subjects with hepatic impairment compared with matched control subjects with normal hepatic function following single SC dose administration.

Detailed Description

A two stage design, open label, multi-center, non-randomized trial to evaluate the the safety and tolerability of a single subcutaneous dose of 5 mg apraglutide in subjects with varying degrees of hepatic function. The hepatic function will estimated with the Child-Pugh classification.

Part 1: 8 subjects with moderate hepatic impairment (Cohort 1) and 8 subjects with normal hepatic function (Cohort 2).

Part 2: 8 subjects with mild hepatic impairment (Cohort 3) and 8 subjects with normal hepatic function (from Cohort 2 where possible and additional subject). Part 2 will be conducted only if the geometric mean ratio (GMR) of AUCinf or AUClast for the moderate hepatic impairment group compared to the control group is ≥2.
