A First-in-human Research Study on How NNC0662-0419 Works in People Living With Overweight or Obesity

September 18, 2025 updated by: Novo Nordisk A/S

A Single- and Multiple-ascending Dose Study to Investigate Safety, Tolerability and Pharmacokinetics of NNC0662-0419 in Participants Living With Overweight or Obesity

This study is testing a new study medicine which may be used to treat people living with overweight or obesity. The purpose of the study is to see if the new study medicine is safe, how it works in human body and what human body does to the study medicine. Participants will either get the study medicine NNC0662-0419 or placebo (a "dummy" medicine without any active ingredients) given by study staff as an injection under participants skin. Which treatment participants will get is decided by chance. NNC0662-0419 is a new medicine, which cannot be prescribed by doctors. This is the first time the medicine is being given to humans. The study will last for about 9 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Male or female (sex at birth)
  • Aged 19-55 years (both inclusive) at the time of signing the informed consent.
  • Body mass index (BMI) between 27.0 and 39.9 kilogram per square meter (kg/m^2) (both inclusive) at screening. Overweight should be due to excess adipose tissue, as judged by the investigator.
  • Considered eligible 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:

  • Known or suspected hypersensitivity to study intervention(s) or related products.
  • Any disorder, unwillingness or inability which in the investigator's opinion might jeopardise participant's safety or compliance with the protocol.
  • 2nd or 3rd degree atrioventricular-block, prolongation of the QRS complex over 120 milliseconds (ms), or of the corrected QT interval by Fridericia (QTcF) calculation over 450 ms (females) or 430 ms (males), or any other clinically significant abnormal ECG results as judged by the investigator, at screening.
  • Glycated haemoglobin (HbA1c) greater than or equal to (>=) 6.5 percent (%) (48 millimoles per mole [mmol/mol]) at screening.
  • Calcitonin >= 50 nanogram per liter (ng/L) at screening

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
