Cagrilintide- Summary
- Dermorphin is a naturally occurring heptapeptide opioid isolated from the skin of South American phyllomedusine frogs. It is one of the most potent endogenous mu-opioid receptor agonists known, approximately 30-40 times more potent than morphine by weight. Explored for pain management and fatigue modulation.
- Cagrilintide is a long-acting amylin analog developed by Novo Nordisk. Amylin is a peptide hormone co-secreted with insulin from pancreatic beta cells. Cagrilintide slows gastric emptying, suppresses glucagon, and reduces appetite via central amylin receptors. In combination with semaglutide (CagriSema), Phase 2 trials achieved approximately 15% body weight reduction. Phase 3 trials (REDEFINE program) are ongoing.
- Half-Life
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- ~7–10 days
- Admin Route
- Subcutaneous (research), Intrathecal (research), Intranasal (research)

- Typical Dose
- Not established for human use; research doses vary widely
- 0.16 mg → 0.3 mg → 0.6 mg → 1.2 mg → 2.4 mg
- Frequency
- Not established
- Once weekly
- Key Benefits
- Potent analgesia superior to morphine on a per-weight basis
- May reduce perception of fatigue in high-intensity activity
- Longer-lasting than endogenous opioids due to D-amino acid substitution
- Research tool for mu-opioid receptor pharmacology
- Potential therapeutic application in refractory pain
- ~15% body weight reduction in combination with semaglutide (CagriSema Phase 2)
- Synergistic appetite suppression complementing GLP-1 receptor agonists
- Reduces post-meal glucagon excursions improving glycemic control
- Slows gastric emptying contributing to prolonged satiety
- Once-weekly dosing via subcutaneous injection
- Potential for greater weight loss than semaglutide monotherapy
- Side Effects
- High addiction and dependence potential (mu-opioid agonism)
- Respiratory depression at high doses
- Nausea, vomiting, constipation
- Sedation and cognitive impairment
