Summary

AMY-101 (also known as Cp40) is a second‑generation compstatin analog, a cyclic 13‑mer peptide that potently inhibits complement C3. It is being evaluated in early‑phase clinical trials for inflammatory and immune‑mediated diseases such as severe COVID‑19, age‑related macular degeneration, and transplant‑related complement activation.

Mechanism of Action

High‑affinity binding to complement component C3, blocking its cleavage and preventing downstream activation of the complement cascade.

Routes of Administration

IntravenousSubcutaneous
