ARA-290 vs Exenatide
Side-by-side comparison of key properties, dosing, and research.
- Summary
- ARA-290 is a synthetic 11-amino acid peptide derived from the helix B region of erythropoietin (EPO). Unlike EPO, it selectively activates the innate repair receptor (IRR) without stimulating hematopoiesis, providing tissue protection, anti-inflammation, and neuropathy relief.
- Exenatide is a GLP-1 receptor agonist derived from the Gila monster lizard peptide exendin-4, with 53% homology to human GLP-1 and natural resistance to DPP-4 degradation. Available as twice-daily (Byetta) or once-weekly (Bydureon) formulation, it is also being studied for Parkinson's disease neuroprotection.
- Half-Life
- ~2–4 hours (SC administration)
- ~2.4 hours (Byetta/twice-daily); Bydureon BCISE: weekly via microsphere release
