• Raising AYVAKIT net product revenue guidance to $435 million to $450 million for 2024

CAMBRIDGE, Mass., Aug. 1, 2024 /PRNewswire/ -- Blueprint Medicines Corporation (Nasdaq: BPMC) today reported financial results, provided a business update for the second quarter ended June 30, 2024, and provided updated financial guidance.

"This quarter marks a milestone, as we celebrate one full year since the U.S. approval of AYVAKIT for indolent systemic mastocytosis. We have delivered yet another very strong quarter of revenue as we continue to build this new rare disease market, and we are well on the path to achieve more than $2 billion in potential peak sales. In addition, we have invested in our next pillars of growth, building on AYVAKIT as the cornerstone of a mast cell disease franchise. Our wild-type KIT inhibitor BLU-808 has entered a Phase 1 healthy volunteer study and we expect to initiate the registration-enabling HARBOR Part 2 study of our next-generation KIT D816V inhibitor elenestinib in indolent systemic mastocytosis later this year," said Kate Haviland, Chief Executive Officer of Blueprint Medicines. "With a significant and growing revenue base from AYVAKIT, a next wave of therapies in our pipeline that we believe can address even larger scale patient opportunities, and a financial profile anchored in sustainable topline revenue growth that enables us the flexibility to invest in the next wave of innovation, we are building Blueprint Medicines for long term value."

Second Quarter 2024 Highlights and Recent Progress

Mast cell disorders

• Achieved AYVAKIT net product revenues of $114.1 million for second quarter of 2024, representing more than 185 percent growth year-over-year.
• Achieved clearance of an Investigational New Drug application for BLU-808 by the U.S. Food and Drug Administration and initiated the healthy volunteer study. BLU-808 is a highly selective and potent investigational oral wild-type KIT inhibitor with best-in-class potential, for chronic urticaria and other mast cell disorders.
• Presented multiple datasets highlighting the long-term safety and durable clinical outcomes of AYVAKIT®/AYVAKYT® (avapritinib) across the spectrum of systemic mastocytosis (SM) at the 2024 European Academy of Allergy and Clinical Immunology (EAACI) and European Hematology Association (EHA) conferences.  Read the presentations here.

Cell cycle inhibition

• Presented data from the Phase 1 VELA study of BLU-222, an oral, potent and selective CDK2 inhibitor, at the 2024 American Society of Clinical Oncology (ASCO) meeting. This is the first positive combination safety data with signals of early clinical activity for a CDK2 inhibitor in combination with an approved CDK4/6 inhibitor, ribociclib, and fulvestrant, in patients with HR+/HER2- breast cancer. Read the presentation here.

2024 Financial Guidance

Blueprint Medicines now anticipates approximately $435 million to $450 million in global AYVAKIT net product revenues for all approved indications in 2024, an increase from the previous range of $390 million to $410 million. The company continues to expect that full-year operating expenses and cash burn will decline in 2024 as compared to 2023, and that its existing cash, cash equivalents and investments, together with anticipated product revenues, will enable the company to maintain a durable capital position to achieve a self-sustainable financial profile.

Key Upcoming Milestones

The company plans to achieve the following remaining milestones in the second half of 2024:

Mast cell disorders

• Initiate registration-enabling Part 2 of the HARBOR trial in indolent systemic mastocytosis (ISM).

Cell cycle inhibition

• Continue strategic business development discussions.
• Complete Phase 1 combination dose escalation for BLU-222 by end of year to inform registration plans.

Second Quarter 2024 Results

• Revenues: Revenues were $138.2 million for the second quarter of 2024, including $114.1 million of net product revenues from sales of AYVAKIT/AYVAKYT and $24.0 million in collaboration, license and other revenues. Revenues were $57.6 million in the second quarter of 2023, including $39.9 million of net product revenues from sales of AYVAKIT/AYVAKYT and $17.7 million in collaboration, license and other revenues. 
• Cost of Sales: Cost of sales was $7.6 million for the second quarter of 2024, as compared to $2.3 million for the second quarter of 2023. The increase was primarily due to the sale of GAVRETO® (pralsetinib) product to Rigel.
• R&D Expenses: Research and development expenses were $84.3 million for the second quarter of 2024, as compared to $110.1 million for the second quarter of 2023. This decrease was primarily due to operational efficiency across our portfolio as we execute across our top priority programs and the timing of manufacturing of clinical trial materials. Research and development expenses included $12.3 million in stock-based compensation expenses for the second quarter of 2024.
• SG&A Expenses: Selling, general and administrative expenses were $89.3 million for the second quarter of 2024, as compared to $71.9 million for the second quarter of 2023. This increase was primarily due to an increase in activities supporting the commercialization of AYVAKIT/AYVAKYT. Selling, general, and administrative expenses included $15.7 million in stock-based compensation expenses for the second quarter of 2024.
• Net Loss: Net loss was $50.0 million for the second quarter of 2024, as compared to a net loss of $132.8 million for the second quarter of 2023.
• Cash Position: As of June 30, 2024, cash, cash equivalents and investments were $868.5 million, as compared to $767.2 million as of December 31, 2023. This increase was primarily due to taking an additional draw under our 2022 debt facility with Sixth Street Partners. Blueprint Medicine's cash and investments provide a durable capital position which, together with anticipated product revenues, the company believes will enable it to reach a self-sustainable financial profile.
