FOXO4-DRI- Summary
- 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.
- FOXO4-DRI is a D-retro-inverso peptide derived from the FOXO4 protein that selectively induces apoptosis in senescent cells. By disrupting the FOXO4-p53 interaction that keeps senescent cells alive, it triggers programmed cell death specifically in these aging, pro-inflammatory cells while sparing healthy tissue.

- Typical Dose
- 0.16 mg → 0.3 mg → 0.6 mg → 1.2 mg → 2.4 mg
- 5 mg/kg in rodent studies; human equivalent approximately 0.5-1 mg/kg
- Frequency
- Once weekly
- 3 consecutive days per cycle
- Key Benefits
- ~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
- Selectively clears senescent cells (senolytics)
- Reduces senescence-associated secretory phenotype (SASP) and chronic inflammation
- Demonstrated restoration of physical fitness in aged mice
- May improve healthspan and reduce age-related tissue dysfunction
- Potential for treatment of age-related pathologies driven by cellular senescence
- Does not affect healthy non-senescent cells at therapeutic doses
- Side Effects
- Nausea (most common, especially during titration)
- Vomiting
- Decreased appetite
- Diarrhea
- +2 more
- Limited human data; largely preclinical evidence
- Possible temporary inflammatory response as senescent cells are cleared (senolytic effect)
- Weight loss observed at high doses in rodent studies
- Unknown long-term safety profile in humans
