PGPIPNGLP-1 / Weight Loss Agonists
Cagrilintide- Summary
- PGPIPN is a bioactive hexapeptide (Pro-Gly-Pro-Ile-Pro-Asn) derived from beta-casein during enzymatic digestion. It exhibits anti-inflammatory properties via opioid receptor modulation and cytokine suppression, making it relevant for gut health, systemic inflammation, and as a component of casein-derived functional foods.
- 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.

- Typical Dose
- 200-500 mg per day
- 0.16 mg → 0.3 mg → 0.6 mg → 1.2 mg → 2.4 mg
- Frequency
- Once or twice daily
- Once weekly
- Key Benefits
- Anti-inflammatory effects via cytokine suppression
- Gut mucosal protection and intestinal barrier support
- Opioid receptor modulation for gut motility regulation
- Potential analgesic activity via central and peripheral opioid pathways
- Explored for inflammatory bowel conditions and gut dysbiosis
- Natural origin (food-derived) with favorable safety profile
- ~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
- Generally very well-tolerated given food-derived origin
- Theoretical opioid-mediated constipation at high doses
- Rare milk protein allergy in casein-sensitive individuals
- Nausea (most common, especially during titration)
- Vomiting
- Decreased appetite
- Diarrhea
