Blueprint Medicines is rapidly advancing a deep pipeline of potent and selective kinase inhibitors for genomically defined subsets of patients with cancer and other debilitating diseases driven by the abnormal activation of kinases. By identifying patients most likely to respond to our therapies, we believe that we can increase the efficiency of drug development and the likelihood of success, delivering transformative medicines for patients who currently lack effective treatments.

Since starting operations in 2011, we have advanced our two lead drug candidates , BLU-285 and BLU-554, into three Phase 1 clinical trials and have multiple discovery-stage programs in our pipeline.

COMMERCIAL RIGHTS
BLU-285 FOR UNRESECTABLE, TREATMENT-RESISTANT GASTROINTESTINAL STROMAL TUMORS (GIST)
 
BLUEPRINT MEDICINES
RESEARCH
CLINICAL DEVELOPMENT
Phase 1

BLU-285 is a potent and selective inhibitor of PDGFRα D842V and KIT Exon 17 mutants, key drivers of metastatic and treatment-resistant GIST, and is being developed for these genomically defined subsets of GIST patients. GIST is the most common form of sarcoma of the gastrointestinal tract.  The PDGFRα D842V mutation is found in an estimated 5 percent of frontline unresectable or metastatic GIST patients, a patient population for which there is no approved medical therapy.  For patients with KIT-driven GIST, treatment with the currently approved therapies often leads to the emergence of KIT Exon 17 mutants and recurrence of disease. In preclinical studies, BLU-285 has demonstrated proof-of-concept and significant anti-tumor activity, including complete and sustained tumor regression, in a preclinical treatment-resistant model of GIST. We have initiated a Phase 1 clinical trial for BLU-285 for the treatment of patients with unresectable, treatment-resistant GIST, and we are currently enrolling patients.

BLU-285 FOR ADVANCED SYSTEMIC MASTOCYTOSIS (SM)
 
BLUEPRINT MEDICINES
RESEARCH
CLINICAL DEVELOPMENT
Phase 1

BLU-285 is a potent and selective inhibitor of PDGFRα D842V and KIT Exon 17 mutants and is being developed as a highly targeted therapy for SM, a disorder of the mast cells in which a KIT Exon 17 mutation is the primary driver of disease. Advanced forms of SM have significant morbidity related to symptoms from mast cell degranulation and shortened life expectancy due to multi-organ dysfunction/failure from mast cell infiltration and tissue destruction.  More than 94 percent of SM patients display the KIT Exon 17 D816V mutation in their mast cells; there is no effective approved targeted therapy for these patients. In preclinical studies, BLU-285 has demonstrated proof-of-concept and resulted in significant disease control in a mouse mast cell tumor model. We have initiated a Phase 1 clinical trial for BLU-285 for treatment of patients with advanced SM, including aggressive SM (ASM), SM with associated clonal hematological non-mast cell lineage diseases (SM-AHN), and mast cell leukemia (MCL), and we are currently enrolling patients.

BLU-554 FOR ADVANCED HEPATOCELLULAR CARCINOMA (HCC)
 
BLUEPRINT MEDICINES
RESEARCH
CLINICAL DEVELOPMENT
Phase 1

BLU-554 is an exquisitely selective and potent kinase inhibitor that we will initially develop for a genomically defined subset of HCC patients. HCC is the most prevalent form of liver cancer and is the second-leading cause of cancer-related deaths worldwide. BLU-554 targets the fibroblast growth factor receptor 4 (FGFR4), while sparing other members of the FGFR family and showing little to no inhibition of all other kinases. Aberrant signaling of FGFR4 is a key driver in up to 30 percent of HCC, and BLU-554 has shown significant anti-tumor activity, including complete and sustained tumor regression, in preclinical models of HCC. We have initiated a Phase 1 clinical trial for BLU-554 for the treatment of patients with advanced HCC, and we are currently enrolling patients.

BLU-667 FOR RET MUTATIONS,FUSIONS, AND PREDICTED RESISTANT MUTANTS
 
BLUEPRINT MEDICINES
RESEARCH
CLINICAL DEVELOPMENT
IND-Enabling Activities

Our drug candidate BLU-667 is a potent and selective inhibitor of the RET mutations, fusions, and predicted resistant mutants. RET fusions are key drivers of multiple cancers, including lung and thyroid cancer, and our research suggests that RET also plays a key role in some colon and breast cancers. By simultaneously targeting the primary driver and predicted resistant mutants that render cancer cells insensitive to treatment with currently approved drugs, our goal is to provide more lasting clinical responses and prevent or delay recurrences of the disease. In preclinical studies, our compounds demonstrated tumor regression in disease models driven by the primary RET fusion and predicted resistance mutants.
