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

VectivBio AG16 enrolled

Overview

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

A two stage design, open label, multi-center, non-randomized trial to evaluate the the safety and tolerability of a single subcutaneous dose of 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 area under the curve extrapolated to infinity (AUCinf) or area under the curve from zero to the last measurable point (AUClast) for the moderate hepatic impairment group compared to the control group is ≥2.

Inclusion Criteria: All Participants: * Age between 18 and 75 years inclusive * Subjects who are willing and able to comply with the study procedures * Subjects able to understand and willing to sign the informed consent * Body mass index (BMI) of ≥18 to ≤35 kg/m2; and a total body weight of \>50 kg (110 lb). * Women of childbearing potential (WOCBP) on highly effective method of contraception during the trial and for 1 month after the end of trial (EOT) visit. Sterilized or infertile or postmenopausal females. * Male subjects with a female partner of childbearing potential: highly effective methods of contraception and no sperm donation during the trial and for 1 month after (EOT) visit. Participants with impaired hepatic function: * Confirmed and documented diagnosis of cirrhosis * Moderate liver disease (Child-Pugh B): clinically stable for at least 1 month prior to screening * Mild liver disease (Child-Pugh A): clinically stable for at least 1 month prior to screening Exclusion Criteria: * History of clinically significant GI, bronchopulmonary, neurological, cardiovascular, endocrine, or allergic disease * Known hypersensitivity to the investigational medicinal product (IMP), any of their excipients or drugs of the same class * If capable of reproduction, unwilling to use an effective form of contraception * If a female of child-bearing potential, a positive urine/blood pregnancy test * Breast-feeding women * Positive urine/blood test for alcohol and drugs of abuse at Screening and on Day-1 * Use of prohibited medications or herbal remedies * Known presence or history of intestinal polyps * Known presence or history of any type of cancer * Pancreatic events such as acute pancreatitis, pancreatic duct stenosis, pancreas infection, and increased blood amylase and lipase (\>2.0-5.0×upper limit of normal range) * Participation in an investigational drug or device study within 30 days prior to Screening * Donation of blood over 500 mL within 2 months prior to Screening * Heavy use of tobacco products (i.e., smokes more than 10 cigarettes per day) * Concomitant disease or condition that could interfere with, or for which the treatment of might interfere with, the conduct of the study, or that would, in the opinion of the Investigator, pose an unacceptable risk to the subject in this trial * Any intercurrent clinically significant illness in the previous 28 days before Day 1 of this study * Positive blood screen for human immunodeficiency virus (HIV) antigen/antibody combo, hepatitis A (HAV), hepatitis B surface antigen (HBsAgB), or hepatitis C virus (HCV) * Unwillingness or inability to comply with the study protocol for any other reason

Area Under the Curve to Infinity (AUCinf) of Apraglutide

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.
