Trial Outcomes & Findings for 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 (NCT NCT05706623)

NCT ID: NCT05706623

Last Updated: 2025-07-10

Results Overview

Apraglutide was quantified in human plasma samples using a fully validated liquid chromatography mass spectrometry-based method, with a lower limit of quantification (LLOQ) of 1 ng/mL and an upper limit of 200 ng/mL. Plasma pharmacokinetic (PK) parameters for apraglutide were estimated using non-compartmental methods from the concentration-time profiles. Actual sampling times, rather than scheduled sampling times, were used. AUCinf was calculated as: AUCinf = AUC from time zero to the last quantifiable concentration (AUClast) + (Clast/kel) where Clast was the observed concentration at the last time point with concentrations above the lower limit of quantification and kel was the terminal elimination rate constant.

Participant Flow

Participants were enrolled in 2 study sites in Slovakia and Germany and participated from February 2023 to April 2023.

In Part 1, participants with normal hepatic function were matched 1:1 for age (±10 years), body mass index (BMI; ±15%), and sex (1:1) to participants with moderate hepatic impairment. Part 2 was to be conducted dependent on the outcome of Part 1 and planned to enroll participants with mild hepatic impairment. No participants enrolled in Part 2.

Terminal elimination rate constant calculated by linear regression of the terminal log-linear portion of the concentration vs. time curve. Linear regression of at least three points and an adjusted r\^2 greater than or equal to 0.80 were required to obtain a reliable kel.

Population: The safety analysis set included all participants who received at least one dose of apraglutide.

A TEAE was any unfavorable and unintended sign, symptom, or disease temporally associated with apraglutide, whether or not related, that occurred or worsened after the dose of apraglutide. A serious TEAE was defined as any TEAE that resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect or was an important medical event. TEAEs were graded for severity based on the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 as follows from Grade 1 (mild) to Grade 5 (AE resulted in death). Clinically significant changes in physical examination findings, laboratory results, vital signs, and 12-lead electrocardiograms (ECGs) were also recorded as TEAEs.
