What is Cagrilintide?

Cagrilintide (research code AM833) is a 37-residue synthetic analogue of the human pancreatic hormone amylin (islet amyloid polypeptide, IAPP), engineered for protease resistance and albumin-binding-mediated long half-life. It is developed by Novo Nordisk as a metabolic-disease candidate, and is studied in combination with Semaglutide (the CagriSema combination) in late-stage clinical programmes.

Mechanism of action

Amylin is a 37-residue pancreatic peptide co-secreted with insulin from β-cells. It binds amylin receptors (heterodimers of the calcitonin receptor with receptor activity-modifying proteins, RAMP1/RAMP2/RAMP3) and produces glucagon suppression, slowed gastric emptying and central satiety signalling. Cagrilintide is engineered to be protease-resistant and to bind albumin via a C18 fatty-acid spacer, producing a plasma half-life of approximately 7 days suitable for once-weekly dosing.

Research context

The CagriSema combination (Cagrilintide + Semaglutide) is in late-stage clinical development for obesity and type-2 diabetes. Cagrilintide alone has progressed through phase II weight-management trials.

Analytical specifications

Every batch of Cagrilintide supplied by NMChem is characterised by reversed-phase HPLC for purity determination and by mass spectrometry for identity confirmation. Certificate of Analysis (COA) documents are issued per batch and made available on request.

Identity is confirmed by electrospray-ionisation mass spectrometry (ESI-MS); the observed mass falls within ±2 Da of the theoretical monoisotopic mass calculated from the residue sequence. Purity is determined by reversed-phase HPLC on a C18 column with a trifluoroacetic-acid-modified water/acetonitrile gradient and reported as the area-under-curve percentage of the main peak at 214 nm. NMChem specification is ≥99% main peak. Material ships as lyophilised powder and must be reconstituted in sterile water or bacteriostatic water immediately before use.

Frequently asked questions about Cagrilintide

What is the CagriSema combination?
CagriSema is the development name for a combination of Cagrilintide (amylin analogue) and Semaglutide (GLP-1 agonist), under investigation by Novo Nordisk for obesity and type-2 diabetes. The two compounds target complementary metabolic pathways and have shown additive weight-reduction effects in phase II studies.
