SYFOVRE (APLS) vs. IZERVAY (Astellas)

Tough month for APLS

• 1st: safety issue surfaces for SYFOVRE

⇨ Retinal Vasculitis

• Now: IZERVAY approved early

⇨ Good for AMD patients to have 2 options


Dosing differences favor SYFOVRE

• SYFOVRE once every 25-60 days

• IZERVAY once monthly


Eye injections

So maybe dosing difference is important?


SYFOVRE safety issue

will be front and center

• Rare issue that seems stable

⇨ Maybe will become minor issue?

⇨ Doesn't appear to be related to MOA


Will a similar safety issue appear for IZERVAY?
