Cagrilintide Quick Start

Cagrilintide is a long-acting amylin analogue developed for once-weekly subcutaneous research. Randomized trials have evaluated it alone and with semaglutide, but trial parameters are not an approved regimen and vendor vials are not clinical-trial products.

Why researchers care

Appetite, weight, and metabolic research

Class

Long-acting acylated amylin analogue

Route reported

Subcutaneous once weekly in clinical trials

Cycle length

Cagrilintide Dosing Protocol and Schedule

The supplied source presents a 0.25-to-2.4 mg weekly titration. Published trials studied several weekly doses, including up to 4.5 mg in Phase 2; the exact ladder shown here is source reported and is not an approved label.

How Cagrilintide Works

Amylin analogue

Designed to activate amylin receptors involved in satiety and meal-related signaling.

Cagrilintide Human Trials and FDA Status

Current status · verified September 15, 2026

Investigational; not FDA approved

  • A 706-participant Phase 2 trial compared weekly cagrilintide doses with placebo and liraglutide over 26 weeks.
  • The 4.5 mg Phase 2 group had greater mean weight reduction than placebo, with gastrointestinal and injection-site events commonly reported.
  • Phase 3 REDEFINE programs have studied cagrilintide alone and in CagriSema over longer periods.
  • Trial formulations, eligibility criteria, titration, and oversight are integral to those results.
  • Cagrilintide is not FDA approved as a standalone medicine.

Who Should Avoid Cagrilintide?

This is an evidence-gap and precaution list, not an approved prescribing label.

Pregnancy or breastfeeding

No approved use or established safety

History of severe gastrointestinal motility disorder

Trial eligibility and amylin-class effects require clinical review

Pancreatitis or gallbladder disease

Potential class-related concerns require medical review

Insulin or sulfonylurea use

Hypoglycemia risk may differ with concomitant therapy

Known ingredient sensitivity

Potential allergic risk

Unsupervised research-vial use

Vendor material is not an approved medicine

Cagrilintide Storage and Handling

Unreconstituted vendor vial

No independently verified cagrilintide-vial stability duration was identified.

Prepared vendor vial

A 28–30 day refrigerated window is community/vendor guidance, not a published stability result.

Clinical-trial formulation

Trial handling cannot be generalized to commercial research vials.

Appearance

Visual inspection cannot establish identity, purity, or sterility.

Cagrilintide Troubleshooting

Calculator differs from another chart

Recheck vial mg, liquid mL, target mg, and U-100 conversion.

Trial and source amounts differ

Preserve each study's dose, formulation, population, and duration.

Combination data appear

Do not assign CagriSema outcomes to cagrilintide alone.

Product testing is pending

Do not describe the exact vial as batch verified until current documents are public.

A scheduled amount is missed

No approved cagrilintide missed-dose instruction exists.
