What is CagriSema?

CagriSema is a once-weekly combination therapy pairing semaglutide with cagrilintide, a novel long-acting amylin analog. By engaging both the GLP-1 and amylin appetite pathways simultaneously, it aims to achieve greater weight management efficacy than either component alone.

Research Applications

Phase 3 REDEFINE program for obesity, type 2 diabetes combination therapy, and comparative studies against semaglutide monotherapy.

Dosage Information (Research Use)

Fixed-dose combination administered once weekly subcutaneously. Titration follows semaglutide-style escalation. Investigational — research use only.

Reconstitution & Handling

Both components reconstituted together or separately depending on research protocol. Standard BAC water.

Half-Life & Pharmacokinetics

Cagrilintide: ~7 days. Semaglutide: ~7 days. Both support once-weekly dosing.

Reported Observations in Literature

GI effects consistent with GLP-1 and amylin agonism: nausea, vomiting, diarrhea. Phase 2 data suggests manageable with titration.

How CagriSema Works

CagriSema combines two distinct mechanisms: cagrilintide (a long-acting amylin analog that activates amylin and calcitonin receptors in the brainstem to reduce appetite and slow gastric emptying) with semaglutide (GLP-1 receptor agonist). The dual pathway approach targets complementary appetite centers — amylin works primarily through the area postrema and nucleus of the solitary tract, while GLP-1 acts on hypothalamic and brainstem GLP-1 receptors.

Research Findings

Phase 3 REDEFINE program ongoing. Phase 2 data showed approximately 15-17% weight loss at 32 weeks — competitive with tirzepatide on a shorter timeline. Represents Novo Nordisk's next-generation approach beyond semaglutide monotherapy. The amylin pathway adds a mechanistically distinct satiety signal.

Dosage & Administration

Fixed-dose combination administered once weekly subcutaneously. Titration follows semaglutide-style escalation. Investigational — research use only.

Safety & Side Effects

GI effects consistent with GLP-1 and amylin agonism: nausea, vomiting, diarrhea. Phase 2 data suggests manageable with titration.
