Mast Cell Connect

In December 2015, Blueprint Medicines established a Mastocytosis Patient Registry with the support of The Mastocytosis Society, Inc. This registry is for patients with any variant of cutaneous or systemic mastocytosis. Patients who participate in this registry are able to review de-identified summaries of responses from other participants.

During the December 2016 American Society of Hematology Annual Meeting, Blueprint Medicines presented the first public report on data from the Mast Cell Connect Registry in a poster titled Systemic Mastocytosis Patient Experience from Mast Cell Connect, the First Patient-Reported Registry for Mastocytosis. The poster can be viewed HERE.
