First Human Dose Trial for a New Medication to Potentially Treat Liver Diseases

Study Overview
=================
Brief Summary
-----------------
This is a single-center, randomized, double-blind, sequential-group, placebo-controlled study with four sequential single ascending dose (SAD) levels in healthy adult participants. This study will assess the safety, tolerability, the pharmacokinetics from single injection (under the skin) of NNC0581 0001 and explores the pharmacodynamics in healthy participants. Participants will be randomized in a 3:1 ratio to receive a fixed single dose (1-day) of NNC0581 0001 or placebo by injections under the skin. Participants will be followed up for 52 weeks post dose.

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Female of non-childbearing potential or male aged 18-55 years (both inclusive) at the time of signing informed consent. Body Mass Index (BMI) from 18.5 to 30.0 kilogram per square meter (kg/m^2) (both inclusive) at screening. Considered to be generally healthy based on the medical history, physical examination, and the results of vital signs, electrocardiogram, and clinical laboratory tests performed during the screening visit, as judged by the investigator. Exclusion Criteria: Any disorder, which in the investigator's opinion might jeopardise participant's safety or compliance with the protocol. Any laboratory safety parameters at screening outside the below laboratory ranges, see laboratory provided reference ranges for specific values (re-screening or re-sampling is NOT allowed if the participant has failed one of the exclusion criteria related to laboratory parameters): Alanine aminotransferase (ALT) greater than upper normal limit (UNL) plus 10 percent Aspartate aminotransferase (AST) greater than UNL plus 10 percent Bilirubin greater than UNL plus 10 percent Estimated glomerular filtration rate (eGFR) below 90 milliliters per minute per 1.73 square meters (90 mL/min/1.73m^2) Glycated haemoglobin (HbA1c) greater than or equal to 5.7 percent (39 millimole per mole [mmol/mol]) at screening.
