CAMBRIDGE, Mass., Aug. 1, 2019 /PRNewswire/ -- Blueprint Medicines Corporation (NASDAQ: BPMC), a precision therapy company focused on genomically defined cancers, rare diseases and cancer immunotherapy, today reported financial results and provided a business update for the quarter ended June 30, 2019.

“The first half of 2019 was a defining period for Blueprint Medicines marked by the submission of our first marketing applications for avapritinib in the United States and Europe, just four years after we initiated clinical development,” said Jeff Albers, Chief Executive Officer of Blueprint Medicines. “As we prepare for the potential launch of avapritinib, we continue to advance our broader portfolio toward critical program milestones, including multiple planned marketing applications for avapritinib and pralsetinib in 2020. In addition, we plan to present initial clinical data from our ongoing Phase 2 PIONEER trial of avapritinib in patients with indolent systemic mastocytosis in the fourth quarter of 2019 and share an update on our research vision and portfolio strategy at our first R&D Day in November 2019.”

Second Quarter 2019 Highlights and Recent Progress:

Avapritinib: Gastrointestinal stromal tumors (GIST)

• Submitted a new drug application (NDA) to the U.S. Food and Drug Administration (FDA) for avapritinib for the treatment of adult patients with PDGFRA exon 18 mutant GIST, regardless of prior therapy, and fourth-line GIST.
• Submitted a marketing authorization application (MAA) to the European Medicines Agency (EMA) for avapritinib for the treatment of adult patients with PDGFRα D842V mutant GIST, regardless of prior therapy, and fourth-line GIST and received EMA validation of the submission. Validation of the MAA confirms that the application is sufficiently complete to begin the formal review process.
• Presented updated clinical data from the ongoing registration-enabling NAVIGATOR trial of avapritinib in patients with PDGFRA Exon 18 mutant GIST and fourth-line GIST at the American Society of Clinical Oncology (ASCO) 2019 Annual Meeting. Read the full data here.
• Dosed the first patient in China in the ongoing Phase 3 VOYAGER trial of avapritinib in patients with third-line GIST, under Blueprint Medicines’ collaboration with CStone Pharmaceuticals.

Avapritinib: Systemic mastocytosis (SM)

• Presented updated clinical data from the ongoing EXPLORER trial of avapritinib in patients with advanced systemic mastocytosis (SM) at the 24^th Congress of the European Hematology Association (EHA). Read the full data here.

Pralsetinib (formerly BLU-667): RET-altered solid tumors

• Presented updated clinical data from the ongoing registration-enabling Phase 1/2 ARROW trial of pralsetinib in patients with RET-altered non-small cell lung cancer (NSCLC), medullary thyroid cancer (MTC) and other cancers at ASCO. Read the full data here.
• Based on encouraging clinical data for pralsetinib in patients with treatment-naïve RET fusion-positive NSCLC and preliminary FDA feedback, expanded the enrollment target for the ARROW trial cohort for treatment naïve patients with RET-fusion NSCLC to enable potential expedited development in first-line NSCLC.

Fisogatinib (formerly BLU-554): Advanced hepatocellular carcinoma (HCC)

• Under Blueprint Medicines’ collaboration with CStone Pharmaceuticals, the China National Medical Products Administration granted approval to conduct a Phase 1b/2 clinical trial evaluating fisogatinib in combination with CS1001, CStone Pharmaceuticals’ anti-PD-L1 inhibitor, in patients with HCC.
• Dosed the first patient in China in the ongoing Phase 1 trial of fisogatinib in advanced HCC, under Blueprint Medicines’ collaboration with CStone Pharmaceuticals.

Key Upcoming Milestones:

The company expects to achieve the following milestones by the end of 2019:

• Complete enrollment in the Phase 3 VOYAGER trial of avapritinib in third-line GIST.
• Initiate the Phase 3 COMPASS-2L precision medicine trial evaluating avapritinib in second-line GIST.
• Present initial data from the Phase 2 PIONEER trial of avapritinib in indolent and smoldering SM.
• Complete enrollment of the Phase 2 PATHFINDER trial of avapritinib in advanced SM.
• Initiate a Phase 3 trial evaluating pralsetinib in first-line RET-fusion NSCLC.
• Initiate a Phase 2 trial evaluating pralsetinib in combination with osimertinib in EGFR-mutant NSCLC harboring an acquired RET alteration.
• Initiate a Phase 1b/2 trial in China evaluating fisogatinib in combination with CS1001, CStone Pharmaceuticals’ anti-PD-L1 inhibitor, in patients with HCC.
• Initiate a Phase 2 trial of BLU-782 in fibrodysplasia ossificans progressiva.
• Share research vision and provide portfolio strategy update at an R&D Day on November 5, 2019, including disclosure of up to two new targets.
• Nominate at least one new wholly-owned discovery program.

Second Quarter 2019 Financial Results:

• Cash Position: As of June 30, 2019, cash, cash equivalents and investments were $667.3 million, as compared to $494.0 million as of December 31, 2018. This increase reflects net proceeds of approximately $327.4 million from the company’s follow-on underwritten public offering of common stock, which closed in April 2019, partially offset by cash used in operations.
• Collaboration Revenues: Collaboration revenues were $5.1 million for the second quarter of 2019, as compared to $41.4 million for the second quarter of 2018. This decrease was primarily due to $40.0 million in revenue recognized under the CStone collaboration in the second quarter of 2018 upon execution of the collaboration agreement. During the second quarter of 2019, the company achieved and recognized a $4.0 million development and regulatory milestone payment under the CStone collaboration.
• R&D Expenses: Research and development expenses were $87.1 million for the second quarter of 2019, as compared to $58.6 million for the second quarter of 2018. This increase was primarily due to increased clinical and manufacturing expenses driven by the company’s lead programs and increased personnel expenses. Research and development expenses included $7.5 million in stock-based compensation expenses for the second quarter of 2019.
• G&A Expenses: General and administrative expenses were $21.9 million for the second quarter of 2019, as compared to $12.3 million for the second quarter of 2018. This increase was primarily due to increased personnel expenses and increased professional fees for commercial-readiness and other activities. General and administrative expenses included $6.2 million in stock-based compensation expenses for the second quarter of 2019.
• Net Loss: Net loss was $99.7 million for the second quarter of 2019, or a net loss per share of $2.04, as compared to a net loss of $27.0 million for the second quarter of 2018, or a net loss per share of $0.62.

Financial Guidance:

Based on its current plans, Blueprint Medicines expects that its existing cash, cash equivalents and investments, excluding any potential option fees and milestone payments under its existing collaborations with Roche and CStone Pharmaceuticals, will be sufficient to enable it to fund its operating expenses and capital expenditure requirements into the middle of 2021.
