Cagrilintide
Summary
Thymosin Alpha-1 is a naturally occurring 28-amino acid peptide derived from the thymus gland. It is a powerful immune modulator approved in many countries for treating chronic hepatitis B, hepatitis C, and as an adjunct in cancer immunotherapy.
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.

Key Benefits
  • Enhances T-cell and NK cell activity
  • Supports recovery from viral and bacterial infections
  • May reduce inflammation systemically
  • Supports healthy aging and immune resilience
  • Improves vaccine response
  • Supports liver health
  • May help with chronic fatigue syndrome and post-viral conditions
  • Approved in multiple countries for hepatitis B and C treatment
  • ~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
  • Injection site irritation
  • Mild flu-like symptoms initially (immune activation)
  • Fatigue (rare)
  • Nausea (most common, especially during titration)
  • Vomiting
  • Decreased appetite
  • Diarrhea
