CAMBRIDGE, Mass., Feb. 15, 2024 /PRNewswire/ -- Blueprint Medicines Corporation (NASDAQ: BPMC) today reported financial results and provided a business update for the fourth quarter and full year ended December 31, 2023 and provided financial guidance.

"As we enter 2024, AVAYKIT continues to be the foundation of our thriving and growing commercial business. Our 2024 guidance of $360 to $390 million sets us up to nearly double AYVAKIT product revenue this year, driven by the launch in ISM as we focus on reaching more patients in both the U.S. and Europe. AYVAKIT's compelling efficacy and safety profile, coupled with the chronic nature of ISM, make the cumulative effect of patients staying on therapy an important revenue driver this year, beyond and in addition to new patient starts. AYVAKIT is firmly on the path to becoming a multibillion-dollar product, providing Blueprint with durable revenue growth well into the next decade. Beyond AYVAKIT and ISM, we are balancing investment in our most compelling pipeline opportunities and maintaining financial discipline, strengthening our financial profile, and accelerating our path to profitability," said Kate Haviland, Chief Executive Officer of Blueprint Medicines. "We are particularly excited about our expanding portfolio targeting allergic-inflammatory diseases where mast cells play a central role, and we are looking forward to sharing more on these programs throughout this year."

Fourth Quarter 2023 Highlights and Recent Progress

Mast cell disorders

• Identified an alternate partner for GAVRETO^® (pralsetinib) in the U.S. and are working with all involved parties to enable continuity of access to GAVRETO in the U.S. The company plans to provide an update to coincide with the late February 2024 termination date of the existing collaboration agreement with Roche.
• The company continues to expect that the wind-down of the Roche collaboration for GAVRETO and the discontinuation of global development and marketing in territories outside the U.S. and Greater China will result in significantly lower year-over-year operating expenses related to GAVRETO and will have no material impact to its overall operating expense plans in 2024.

2024 Financial Guidance

Blueprint Medicines today announced it anticipates approximately $360 million to $390 million in global AYVAKIT net product revenues for all approved indications in 2024. The midpoint of this range represents more than 80 percent year-over-year revenue growth, the majority of which is expected to be driven by ISM. The company continues to expect that operating expenses and cash burn will further decline in 2024, and that its existing cash, cash equivalents and investments, together with anticipated future product revenues, will maintain a durable capital position to enable the company to achieve a self-sustainable financial profile.

Key Upcoming Milestones

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

Mast cell diseases

• Present long-term safety and efficacy data from the PIONEER trial of AYVAKIT in ISM at the 2024 American Academy of Allergy, Asthma and Immunology (AAAAI) Annual Meeting.
• Present preclinical data for BLU-808, a highly selective and potent oral inhibitor of wild-type KIT, at the 2024 AAAAI Annual Meeting.
• Submit an investigational new drug application for BLU-808 in the second quarter of 2024.

Breast cancer and other solid tumors

• Continue ongoing strategic business development discussions.
• Present data for BLU-222 in combination with ribociclib and fulvestrant in patients with HR+/HER2- breast cancer in the first half of 2024.

Fourth Quarter and Year End 2023 Results

• Revenues: Revenues were $72.0 million for the fourth quarter of 2023, including $71.0 million of net product revenues from sales of AYVAKIT/AYVAKYT and $0.9 million in collaboration revenues. Revenues for the year ended December 31, 2023 were $249.4 million, including $204.2 million of net product revenues from sales of AYVAKIT/AYVAKYT, and $45.2 million in collaboration and license revenues.

• Cost of Sales: Cost of sales was $0.3 million for the fourth quarter of 2023 and $8.5 million for the year ended December 31, 2023, as compared to $4.8 million and $17.8 million for the fourth quarter and year ended December 31, 2022, respectively. This decrease was mainly due to a decrease in inventory write-downs and the cost of collaboration-related sales.
• R&D Expenses: Research and development expenses were $97.5 million for the fourth quarter of 2023 and $427.7 million for the year ended December 31, 2023, as compared to $117.8 million and $477.4 million for the fourth quarter and year ended December 31, 2022, respectively. This decrease was primarily due to a focused approach towards optimizing operational efficiency across Blueprint Medicine's portfolio as the company executes across its top priority programs and the timing of manufacturing of clinical trial materials. Research and development expenses also included $10.0 million in stock-based compensation expenses for the fourth quarter of 2023 and $41.5 million in stock-based compensation for the year ended December 31, 2023.

This increase was primarily due to an increase in compensation and personnel related costs driven by the company's first quarter 2023 field force expansion to support the AYVAKIT launch in ISM and an increase in commercial and related activities primarily related to the commercialization of AYVAKIT/AYVAKYT. Selling, general and administrative expenses included $12.6 million in stock-based compensation expenses for the fourth quarter of 2023 and $51.1 million in stock-based compensation for the year ended December 31, 2023.
