How AYVAKIT may help

Discover how AYVAKIT performed in clinical trials

AYVAKIT was studied in 2 clinical trials to determine if it was safe and effective for patients with AdvSM. In the studies, 53 patients had their response to treatment with AYVAKIT evaluated.

All 3 subtypes of AdvSM were represented (ASM, SM-AHN and MCL) and doses were taken as prescribed.

57%

of Patients Responded to Treatment with AYVAKIT

  • Of the 53 patients with AdvSM treated with AYVAKIT, 30 (57%) showed improvement in their disease. Improvement was defined as a treatment response at 12 or more weeks, and the resolution of or partial recovery from damage to one or more organs affected by AdvSM. A change in the number of mast cells in bone marrow and a decrease in the level of activation of mast cells by at least 50% were also evaluated.
  • About half the patients responded to treatment within the first 2.1 months after starting therapy.

Individual results may vary. It is important to note that having a response to treatment does not mean a person’s AdvSM has been cured.

Bleeding in your brain:
