CAMBRIDGE, Mass., February 6, 2020 – Blueprint Medicines Corporation (NASDAQ: BPMC), a precision therapy company focused on genomically defined cancers, rare diseases and cancer immunotherapy, today announced that the U.S. Food and Drug Administration (FDA) has extended the Prescription Drug User Fee Act (PDUFA) date for its New Drug Application (NDA) seeking accelerated approval of avapritinib for the treatment of adults with fourth-line gastrointestinal stromal tumor (GIST). The FDA extended the PDUFA action date by three months from February 14, 2020 to May 14, 2020.
As previously announced, the FDA has requested top-line data from Blueprint Medicines’ ongoing Phase 3 VOYAGER clinical trial, which is comparing avapritinib to regorafenib in third- or fourth-line GIST, to inform the pending action on the NDA for fourth-line GIST. Blueprint Medicines expects to provide the top-line data to the FDA early in the second quarter of 2020 to enable the FDA to take action by the May 14, 2020 PDUFA date.
In addition, Blueprint Medicines today announced that the National Comprehensive Cancer Network has updated its Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Soft Tissue Sarcoma to include avapritinib as a recommended category 2A treatment for unresectable or metastatic GIST with a PDGFRA exon 18 mutation, including PDGFRA D842V mutations, as well as fourth-line GIST. This rating indicates that there is uniform NCCN consensus that the intervention is appropriate. The NCCN Guidelines are the recognized clinical standard for cancer care by U.S. healthcare providers and payers, and are maintained by a committee of expert physicians from leading U.S. cancer centers.
About AYVAKIT™ (avapritinib)
AYVAKIT (avapritinib) is a kinase inhibitor approved by the FDA for the treatment of adults with unresectable or metastatic GIST harboring a PDGFRA exon 18 mutation, including PDGFRA D842V mutations. AYVAKIT is a selective and potent inhibitor of KIT and PDGFRA mutant kinases. It is the only FDA-approved type 1 inhibitor for GIST that works by directly binding to the active kinase conformation from which mutant KIT and PDGFRA signal. AYVAKIT has demonstrated inhibition of a broad range of KIT and PDGFRA mutations associated with GIST, including potent clinical activity against activation loop mutations that are associated with resistance to currently approved therapies. For more information, visit AYVAKIT.com.
Avapritinib is not approved for the treatment of any other indication, including fourth-line GIST, in the U.S. or any other jurisdiction by the FDA or any other health authority.
Blueprint Medicines is pursuing a broad clinical development program for avapritinib across multiple lines of GIST treatment, as well as for advanced, smoldering and indolent systemic mastocytosis (SM). The FDA has granted Breakthrough Therapy Designation to avapritinib for two indications: one for the treatment of unresectable or metastatic GIST harboring the PDGFRA D842V mutation and one for the treatment of advanced SM, including the subtypes of aggressive SM, SM with an associated hematologic neoplasm and mast cell leukemia. For more information about avapritinib clinical trials, visit www.clinicaltrials.gov or www.blueprintclinicaltrials.com.

Intracranial hemorrhage (e.g., subdural hematoma, intracranial hemorrhage, and cerebral hemorrhage) occurred in 1% of 267 patients (0.7% Grade 3 or 4) with GIST and overall in 3% of 335 patients (1.2% Grade 3 or 4) who received AYVAKIT. Overall, 0.9% of patients receiving AYVAKIT required permanent discontinuation for an intracranial hemorrhage.
