Cagrilintide / CagriSema
Complete Research Guide
Open each section for the available evidence. Gaps are stated rather than inferred.
Overview
Cagrilintide / CagriSema is listed as metabolic / long-acting amylin analog.
- •Obesity (investigational)
Regulatory status: Investigational (Novo Nordisk, Phase 3 REDEFINE).
Structure & Properties
Compound: Cagrilintide / CagriSema; also known as AM833, Cagrilintide + Semaglutide.
Pharmacologic class: Metabolic / Long-acting Amylin Analog.
Known delivery routes: Subcutaneous.
Sequence, molecular weight, salt form, and excipient details are formulation-specific and are not listed unless verified by a manufacturer or laboratory COA.
How It Works
Long-acting amylin receptor agonist — slows gastric emptying and suppresses postprandial glucagon; synergistic with GLP-1 (semaglutide).
- •Additive weight loss with GLP-1
- •Improved satiety
- •Glycemic control
Human Research
Evidence grade: Clinical RCT (Limited)
Clinical RCT (Limited). Phase 3 REDEFINE-1 reported ~22% weight loss.
Laboratory Research
Phase 3 REDEFINE-1 reported ~22% weight loss
Preclinical findings describe biological plausibility, not proven benefit in people. Animal and laboratory doses do not translate directly to human use.
Processing & Interactions
Timing and exposure
Once weekly, with or without food.
Potential interactions and combinations to avoid
- •Pramlintide (same amylin class)
Absorption, half-life, metabolism, and clearance can vary by formulation and route. Use prescribing information when an approved product exists.
Safety & Precautions
Known or reported risks
- •Nausea, vomiting
- •Injection-site reactions
- •Hypoglycemia (with insulin/SU)
Contraindications
- •MTC / MEN-2 (when combined with semaglutide)
- •Pregnancy
- •Personal or family history of medullary thyroid carcinoma or MEN-2 syndrome
- •History of pancreatitis or unexplained elevated lipase/amylase
- •Gastroparesis, severe GERD, or chronic gastrointestinal motility disorder
- •History of symptomatic gallstones or biliary disease
- •Active eating disorder, malnutrition, or BMI already in the underweight range
- •Type 1 diabetes as monotherapy for glycemic control
- •Planned surgery/anesthesia without pre-procedure fasting adjustment (aspiration risk)
- •Proliferative diabetic retinopathy with rapid glycemic lowering
- •Severe renal impairment with ongoing dehydration or vomiting
- •Bleeding disorders or anticoagulant therapy without physician guidance (injection-site haematoma)
- •Active skin infection, cellulitis, or lipohypertrophy at intended injection sites
- •Inability to maintain sterile technique or safe sharps disposal
- •Not FDA-approved for human therapeutic use — no verified purity, sterility, or potency standards
- •Immunocompromised or transplant patients (unverified sterility and immunogenicity risk)
- •Concurrent participation in drug-tested sport (WADA prohibited or non-cleared substance)
- •Known hypersensitivity or prior reaction to this compound or any excipient/diluent
- •Pregnancy, attempting conception, or breastfeeding unless prescribed and monitored by a physician
- •Children and adolescents with open growth plates (unless under specialist endocrine care)
- •Active or recently treated malignancy without oncology clearance
- •Use without a confirmed diagnosis, baseline labs, and licensed clinical supervision
Unknown long-term toxicity should be assumed where controlled human data are limited. Seek urgent care for a severe or unexpected reaction.
Administration & Studied Formulations
Reference range: 0.16–2.4 mg/week (mono); CagriSema 2.4/2.4 mg in trials
Frequency: Weekly
Cycling: Continuous with stepwise titration.
Subcutaneous (SubQ)
Default route for most research and therapeutic peptides — best absorption for reconstituted powder.
31G × 5/16" insulin syringe (U-100). 100 units = 1 mL. Pinch skin at abdomen (2" from navel), outer thigh, or love handle. Insert at 45–90°. Rotate sites daily to prevent lipohypertrophy. Alcohol-swab site, air-dry, inject slow, hold 5 sec.
Dosing information is educational context, not a personal recommendation. Approved products must follow their label and prescriber instructions.
Applications & Related Therapies
Potentially complementary measures
- •Semaglutide (CagriSema is the intended combination)
Clinical use should account for diagnosis, approved alternatives, nutrition, activity, sleep, rehabilitation, current medicines, and appropriate monitoring.
Cases, Considerations & Ethics
Decision framework: establish the clinical goal, confirm evidence quality and legal status, screen contraindications and interactions, compare approved alternatives, define monitoring and stopping criteria, and use shared decision-making with a licensed clinician.
Case evidence: individual reports cannot establish safety or effectiveness and should not outweigh controlled trials.
Ethics: informed consent should distinguish established care from experimental use, disclose uncertainty and cost, avoid overstated claims, and never substitute research products for medically necessary care.
Function
Dosing
Recommended Time of Day
Same day each week, any time of day — often paired with weekly semaglutide.
See “Timing & Interactions” below for full fasted/fed circumstances, what to avoid combining, and what pairs well.
Administration & Technique
Injection & Application Sites
- Abdomen — 2 in (5 cm) away from the navel, either side. Fastest, most consistent SubQ absorption.
- Flank / love handle — Lateral fat pad above the hip. Good rotation site when the abdomen is tender.
- Outer thigh — Upper outer quadrant, a hand-width below the hip. SubQ pinch at 45°.
Diagram is a general illustration, not a medical instruction. Rotate sites every injection, keep 1 in (2.5 cm) between recent sites, and avoid scars, moles, bruises and the navel area.
Cycling
Continuous with stepwise titration.
Timing & Interactions
- ·Pramlintide (same amylin class)
- ·Semaglutide (CagriSema is the intended combination)

1 mL = 100 units on a standard U-100 insulin syringe. Draw to the nearest 0.5 unit and confirm dosing with a clinician before injection.
