How Does Avacincaptad Pegol Affect Complement C5?

Avacincaptad pegol binds to and inhibits complement protein C5. Blocking C5 reduces its cleavage into C5a and C5b and decreases formation of the membrane attack complex. Complement activity is involved in age-related macular degeneration biology, though the exact relationship between C5 inhibition and clinical outcomes in geographic atrophy is not fully established.

Who Is Treated With Avacincaptad Pegol?

Avacincaptad pegol is approved for geographic atrophy secondary to age-related macular degeneration. It is administered to each affected eye by a qualified physician. The medicine is contraindicated when an ocular or periocular infection is present or when the eye has active intraocular inflammation.

How Often Is Avacincaptad Pegol Injected?

The recommended dose is 2 mg in 0.1 mL injected into each affected eye once monthly, approximately every 28 days with a seven-day window before or after that interval. Each vial is for a single eye and single use. Intravitreal administration requires aseptic preparation and injection technique.

What Eye Risks Need Monitoring With Avacincaptad Pegol?

Intravitreal injections can cause endophthalmitis and retinal detachment. Avacincaptad pegol treatment is also linked with neovascular age-related macular degeneration and temporary increases in intraocular pressure. Common adverse reactions include conjunctival hemorrhage, increased eye pressure, blurred vision, punctate keratitis, and eye pain. New vision changes or eye pain need prompt evaluation.
