In the second quarter, we delivered strong growth in AYVAKIT revenue and patients on therapy, reinforcing our belief in the blockbuster potential for AYVAKIT in systemic mastocytosis," said Kate Haviland, Chief Executive Officer of Blueprint Medicines. "We also achieved important regulatory and operational milestones, including multiple readouts from our pipeline at ASCO and the nomination of a selective and potent inhibitor of wild-type KIT which leverages our expertise and infrastructure as we build a franchise in mast cell driven diseases. Our year-to-date achievements fortify our strong foundation for near- and long-term growth."

Second Quarter 2023 Highlights and Recent Progress

Systemic mastocytosis (SM) and other mast cell disorders

• Announced that the U.S. Food and Drug Administration (FDA) approved AYVAKIT® (avapritinib), the first and only medicine approved for the treatment of adults with indolent systemic mastocytosis (ISM) and the only treatment approved across the spectrum of indolent and advanced SM. Read the press release here.
• Published detailed results from the PIONEER study in New England Journal of Medicine (NEJM) Evidence. Key results demonstrate that AYVAKIT achieved statistically significant and clinically meaningful benefits in overall symptoms and objective measures of mast cell burden compared to placebo at 24 weeks, with improvements deepening through 48 weeks. Data also show meaningful improvements in quality-of-life measurements. AYVAKIT showed a favorable safety profile compared to placebo. Read the press release here.
• Announced nomination of BLU-808, an oral, highly potent and selective wild-type KIT inhibitor with first- and best-in-class potential, as a development candidate for the treatment of mast cell disorders, including chronic urticaria.

Cancers vulnerable to CDK2 inhibition

• Presented monotherapy dose escalation data from the Phase 1/2 VELA trial of BLU-222 in patients with cancers vulnerable to CDK2 inhibition at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting. The results showed evidence of favorable safety, cell cycle modulation and clinical response, supporting initiation of combination dose escalation of BLU-222 with ribociclib and fulvestrant in patients with hormone receptor-positive/HER2-negative breast cancer.

EGFR-driven non-small cell lung cancer (NSCLC)

BLU-945

• Presented dose escalation data from the Phase 1/2 SYMPHONY study of BLU-945 in patients with late-line EGFR-driven NSCLC at the 2023 ASCO Annual Meeting. BLU-945 monotherapy and in combination with osimertinib showed evidence of clinical activity and was generally well tolerated, with infrequent adverse events associated with wild-type EGFR inhibition, supporting continued combination dose escalation. Find the poster here.

BLU-451

• Presented dose escalation data from the Phase 1/2 CONCERTO study of BLU-451 in patients with NSCLC driven by EGFR exon 20 insertions and atypical mutations at the 2023 ASCO Annual Meeting. Results showed evidence of safety and clinical benefit, including central nervous system activity, supporting continued dose escalation. Find the poster here.

Key Upcoming Milestones

Blueprint Medicines plans to achieve the following milestones by the end of 2023:

• Present data from Part 1 of the HARBOR trial of elenestinib in indolent SM.
• Continue AYVAKIT commercial launch execution in SM.

Second Quarter 2023 Results

• Cost of Sales: Cost of sales was $2.3 million for the second quarter of 2023, as compared to $4.9 million for the second 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 $110.1 million for the second quarter of 2023, as compared to $128.5 million for the second quarter of 2022. This decrease was primarily due to continued operational efficiency gains 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 $10.2 million in stock-based compensation expenses for the second quarter of 2023.
• SG&A Expenses: Selling, general and administrative expenses were $71.9 million for the second quarter of 2023, as compared to $58.7 million for the second 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 $13.6 million in stock-based compensation expenses for the second quarter of 2023.
• Net Loss: Net loss was $132.8 million for the second quarter of 2023, or a net loss per share of $2.19, as compared to a net loss of $159.7 million for the second quarter of 2022, or a net loss per share of $2.68.
