Weight Management

Cagrilintide is a long-acting acylated amylin analog developed by Novo Nordisk for the treatment of obesity and weight management. Amylin is a peptide hormone co-secreted with insulin from pancreatic beta cells that plays a role in appetite regulation, gastric emptying, and postprandial glucose control. Cagrilintide has been engineered with fatty acid acylation to extend its half-life, enabling once-weekly subcutaneous dosing.

How it works

Activates amylin receptors (calcitonin receptor plus RAMP1/2/3 complexes) in the area postrema and hypothalamus, promoting satiety and reducing food intake.

Slows gastric emptying, which contributes to prolonged feelings of fullness after meals and reduces postprandial glucose excursions.

May modulate glucagon secretion, reducing hepatic glucose output and contributing to improved glycemic control.

Weeks 1-4: Appetite changes begin during dose escalation. GI side effects most common in this period. Weight loss of 1-3% may occur.

Each reference below was re-fetched from its PubMed record, and the quoted sentence was confirmed to appear in that abstract and to support the claim it sits under. Follow any of them to read the source.

Dose/route boundary: once-weekly subcutaneous cagrilintide was studied at 0.3-4.5 mg, not the page’s 0.25 mg starting dose.

Participants were randomly assigned (6:1) to subcutaneous self-injections of once-weekly cagrilintide (0·3, 0·6, 1·2, 2·4, or 4·5 mg), once-daily liraglutide 3·0 mg, or volume-matched placebo (for six placebo groups).

Evidence scope. Human phase 2 trial in adults with overweight/obesity without diabetes; subcutaneous self-injection once weekly, with up to six weeks of dose escalation.

Mechanism/class: cagrilintide is a long-acting amylin analogue under investigation for weight management.

Evidence scope. Definitional statement from a human phase 2 trial; it does not establish every receptor-level detail on the page.

Primary safety: gastrointestinal disorders including nausea, constipation, and diarrhea, plus administration-site reactions, were the most frequent adverse events.

The most frequent adverse events were gastrointestinal disorders (eg, nausea, constipation, and diarrhoea) and administration-site reactions.

Evidence scope. Human phase 2 trial; adults with overweight/obesity without diabetes; once-weekly SubQ doses 0.3-4.5 mg for 26 weeks.

Claims we could not support

No abstract we checked supports these for this molecule at this route. That is not the same as saying they are false — it marks where the evidence is missing.

Exact starting dose: 0.25 mg SubQ weekly. The checked phase 2 abstract started its studied dose range at 0.3 mg weekly. No checked abstract verified 0.25 mg.

Interactions & stacking

Two different questions: what is documented about running these together, and what is documented about drawing them into the same syringe. A good pharmacological partner can still have to be pinned separately.

Documented together

SemaglutideCagriSema combination shows synergistic weight loss via complementary amylin + GLP-1 pathways.

Check any specific pair in the Stack & Interaction Checker, which answers both questions separately. Absence of a documented conflict is not evidence of safety.
