A Research Study to Evaluate the Safety of NNC1679-0001 When Given to Healthy Participants and Participants With T2DM

May 15, 2026 updated by: Novo Nordisk A/S

A Phase 1,Double-blinded,Placebo-controlled Study to Investigate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single Ascending Doses of NNC1679-0001 When Administered to Healthy Participants and Participants With T2DM

This study is testing a new medicine that might help treat people with type 2 diabetes. The purpose of the study is to see if the new study medicine is safe and how well is tolerated by the body. There will be two groups of participants in this study: healthy participants and participants with type 2 diabetes. Participant will either get study medicine (NNC1679-0001) or placebo (a treatment that has no active medicine in it). NNC1679-0001 is a new experimental medicine that doctors cannot prescribe yet. Which treatment the participant gets is decided by chance. Participant will get one dose which will be injected into the area around abdomen (belly) by the medical staff.

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

Yes

Description

Inclusion Criteria:

All participants

  • Glycated haemoglobin (HbA1c) lesser than or equal to (<=) 6.4 percent (%) (47 [millimoles per mole] mmol/mol) at screening.
  • Considered to be generally healthy based on the medical history, physical examination, and the results of vital signs, electrocardiograms (ECG), and clinical laboratory tests performed during the screening visit, as judged by the investigator.

Participants with Type 2 Diabetes Mellitus (T2DM)

  • BMI 20.0-34.9 kg/m^2 (both inclusive) at screening.
  • HbA1c 6.3-8.5% (45.4-69.4 mmol/mol) at screening.
  • Diagnosed with T2DM greater than or equal to (>=)180 days before screening.
  • Stable (as judged by the investigator) daily dose(s) of metformin or combination of metformin and dipeptidyl peptidase IV (DPP-4) inhibitors >= 90 days before screening.

Exclusion Criteria:

All participants

  • Screening alanine aminotransferase (ALT) values greater than (>) upper limit of normal (ULN) +10%, aspartate aminotransferase (AST) values >ULN +20%, or total bilirubin >ULN.
  • Renal impairment, defined as estimated glomerular filtration rate (eGFR) <60.0 milliliter per minute per 1.73 square meter (mL/min/1.73m^2), at screening.
  • Clinical evidence of chronic kidney disease (CKD) and/or urinary albumin: creatinine ratio (UACR) >30 milligrams per gram (mg/g).
  • Presence or history of cardiovascular disease, including stable and unstable angina pectoris, myocardial infarction, transient ischaemic attack, stroke, cardiac decompensation, clinically significant arrhythmias, or clinically significant conduction disorders.

Healthy participants

  • Any disorder that, in the investigator's opinion, might jeopardise participants' safety or compliance with the protocol.
  • Supine blood pressure at screening outside the range of 90-139 millimeters of mercury (mmHg) for systolic or 50-89 mmHg for diastolic.

Participants with T2DM

  • Any disorder except for mild conditions under stable treatment associated with T2DM, which in the investigator's opinion might jeopardise participant safety or compliance with the protocol.
  • Supine blood pressure at screening outside the range of 90-159 mmHg for systolic or 50-99 mmHg for diastolic. This exclusion criterion also pertains to those participants who are receiving antihypertensive treatment.
