Understanding the Effect of CagriSema, Cagrilintide, and Semaglutide on Muscle Health (Role of Amylin Signature in Muscle Health) (RASMUS)

May 3, 2026 updated by: Novo Nordisk A/S

Effect of CagriSema, Semaglutide and Cagrilintide on Skeletal Muscle Insulin Sensitivity, Composition and Function

The purpose of this clinical study is to look into how study medicines CagriSema (cagrilintide and semaglutide), cagrilintide, and semaglutide affects muscle health in people with excess body weight and slightly higher than normal blood sugar as they lose weight. Participants will either get CagriSema (a new study drug), cagrilintide (a new study drug), semaglutide (a drug that doctors can already prescribe to treat people with type 2 diabetes and excess body weight) or placebo (a placebo looks like the treatment being tested but doesn't have any active ingredients in it). Which treatment participants will get is decided by chance. Participants will be in this clinical study up to 15 months.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

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
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion criteria

  • Male or female.
  • Age 50-70 years (both inclusive) at the time of signing the informed consent.
  • Body Mass index (BMI) between 30.0 kilograms per square meter (kg/m^2) and 39.9 kg/m^2 (both inclusive) at screening (V1).
  • Excess body weight should be due to excess adipose tissue, as judged by the investigator.
  • Participant has a wish to lose at least 25 percentage (%) of body weight within 52 weeks of treatment.

Exclusion criteria

  • Any leg amputations.
  • Female participants who are not postmenopausal at screening.
  • Any clinically significant body weight change (greater than or equal to [>=] 5% self-reported change) or dieting attempts within 90 days before screening.
  • Treatment with any glucagon-like peptide-1 (GLP-1) receptor agonist or a medication with GLP-1 activity within 90 days before 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.
Outcome Measure
Measure Description
Time Frame
Change in insulin-stimulated fluorodeoxyglucose (FDG) uptake in skeletal muscle
Time Frame: Baseline to Week 51
Measured in micromoles per 100 grams per minute (μmol/100g/min).
Baseline to Week 51

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

Change in insulin-stimulated FDG uptake in skeletal muscle
Time Frame: Baseline to Week 20
Measured in μmol/100g/min.
