CagriSema vs Octreotide

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

CagriSema

CagriSema is a fixed-ratio combination of cagrilintide (a long-acting amylin analog) and semaglutide, developed by Novo Nordisk. By combining two distinct appetite-regulating peptide hormones, CagriSema aims to achieve greater weight loss than semaglutide alone. Phase 3 data showed 22.7% body weight reduction, and an FDA response is expected in 2026.

Octreotide

Octreotide (Sandostatin) is a synthetic somatostatin analog FDA-approved for acromegaly, carcinoid tumors, and VIPomas. It inhibits growth hormone and various GI hormones.

Side-by-Side Comparison

AspectCagriSemaOctreotide
MechanismCagriSema combines two complementary peptide mechanisms: (1) Semaglutide — GLP-1 receptor agonist providing glucose-dependent insulin secretion, glucagon suppression, delayed gastric emptying, and hypothalamic appetite suppression. (2) Cagrilintide — a long-acting analog of amylin, a peptide hormone co-secreted with insulin from pancreatic beta cells. Amylin activates amylin receptors (calcitonin receptor + RAMP complexes) in the area postrema and hypothalamus, providing additional appetite suppression via a distinct neuronal pathway from GLP-1. The combination produces additive weight loss by engaging two independent satiety signaling systems.Binds to somatostatin receptors (primarily SSTR2 and SSTR5) to inhibit GH, glucagon, insulin, and gastric secretions. Reduces blood flow to GI tract and inhibits tumor hormone secretion.
Typical DosagePhase 3 trial doses: cagrilintide 2.4 mg + semaglutide 2.4 mg weekly (fixed combination in a single injection). Dose escalation: start at cagrilintide 0.15 mg / semaglutide 0.25 mg weekly and escalate over 16 weeks to the maintenance dose. Administered as a single injection combining both peptides.Varies by indication. Acromegaly: 50-100mcg three times daily initially, up to 500mcg TID. LAR (long-acting): 20-30mg IM every 4 weeks.
AdministrationSingle subcutaneous injection once weekly, combining both peptides. Pre-filled pen device. Not yet commercially available. FDA response expected 2026.Subcutaneous injection for immediate-release (between meals). Intramuscular for LAR depot form. Requires monitoring of gallbladder, glucose, and thyroid.
Side EffectsPhase 3 data: nausea, vomiting, diarrhea, constipation (similar profile to semaglutide alone, but some reports suggest modestly higher GI rates). Decreased appetite. Injection site reactions.GI effects (diarrhea, nausea, abdominal pain), gallstones (up to 25% of long-term users), injection site reactions, and blood glucose changes.
