CAMBRIDGE, Mass., Oct. 26, 2023 /PRNewswire/ -- Blueprint Medicines Corporation (NASDAQ: BPMC) today reported financial results and provided a business update for the third quarter ended September 30, 2023.

"In the first full quarter following AYVAKIT's launch in indolent systemic mastocytosis, we saw strong and steady growth in both patients treated and revenue, reflecting a highly favorable reception to AYVAKIT's unique and compelling clinical profile and the effectiveness of our ongoing efforts to bring AYVAKIT to all patients who can benefit from treatment," said Kate Haviland, Chief Executive Officer at Blueprint Medicines. "Through the end of this year and into 2024, we anticipate continued steady growth in AYVAKIT revenue driven by both existing and new prescribers as we execute a disciplined approach to managing operating expenses and allocating capital to our most important investments."

Third Quarter 2023 Results

• Revenues: Revenues were $56.6 million for the third quarter of 2023, including $54.2 million of net product revenues from sales of AYVAKIT/AYVAKYT and $2.4 million in collaboration revenues. Blueprint Medicines recorded revenues of $65.9 million in the third quarter of 2022, including $28.6 million of net product revenues from sales of AYVAKIT/AYVAKYT and $37.3 million in collaboration and license revenues.
• Cost of Sales: Cost of sales was $2.8 million for the third quarter of 2023, as compared to $3.0 million for the third quarter of 2022. The decrease was primarily due to a decrease in the cost of collaboration-related sales.
• R&D Expenses: Research and development expenses were $110.3 million for the third quarter of 2023, as compared to $128.0 million for the third quarter of 2022. This decrease was primarily due to a focused approach towards optimizing 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 $11.2 million in stock-based compensation expenses for the third quarter of 2023.
• SG&A Expenses: Selling, general and administrative expenses were $70.7 million for the third quarter of 2023, as compared to $57.6 million for the third quarter of 2022. This increase was primarily due to an increase in compensation and personnel related costs driven by our first quarter field force expansion to support the AYVAKIT launch in ISM. Selling, general, and administrative expenses included $11.9 million in stock-based compensation expenses for the third quarter of 2023.
• Net Loss: Net loss was $133.7 million for the third quarter of 2023, or a net loss per share of $2.20, as compared to a net loss of $133.2 million for the third quarter of 2022, or a net loss per share of $2.23.
