In indolent systemic mastocytosis. It's out of view, too many mast

cells passing through. They build up fast, they overreact. Where ISM symptoms

start, that's a fact. So it's not just what you feel or see,

it starts deeper in your biology. Adding AYVAKIT AYVAKIT

it works at the source inside. Blocking the signal that tells mast cells to multiply.

It blocks symptoms before they begin. In clinical studies, many saw significant relief set in.

Treat ISM at the source bit by bit. For an ISM treatment that

just fits, it's gotta be AYVAKIT.
