CAMBRIDGE, Mass., May 9, 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 March 31, 2019.

“Based on significant clinical and regulatory progress in the first quarter, we accelerated multiple programs and advanced our ‘2020 Blueprint’ strategy to transform Blueprint Medicines into a fully-integrated precision therapy company,” said Jeff Albers, Chief Executive Officer of Blueprint Medicines. “We are especially encouraged that the FDA granted Breakthrough Therapy Designation to BLU-667 for RET-fusion-positive NSCLC, and we look forward to presenting updated data from our Phase 1 ARROW trial at the ASCO Annual Meeting next month. In addition, our follow-on public offering in April further strengthened our financial position, enabling us to continue to build the company ahead of multiple planned marketing applications for avapritinib and BLU-667 in the United States and Europe over the next 18 months.”

First Quarter 2019 Highlights and Recent Progress:

Avapritinib: Gastrointestinal stromal tumors (GIST):

Avapritinib: Systemic mastocytosis (SM):

• Announced plans to accelerate the submission of a new drug application (NDA) to the U.S. Food and Drug Administration (FDA) for avapritinib for the treatment of advanced SM in the first quarter of 2020, subject to continuing discussions with the FDA to determine the required clinical data for an NDA submission.

BLU-667: RET-altered solid tumors:

• Received FDA Breakthrough Therapy Designation for BLU-667 for the treatment of patients with RET fusion-positive non-small cell lung cancer (NSCLC) that has progressed following platinum-based chemotherapy.

• Achieved enrollment targets for registration-enabling ARROW trial cohorts for patients with previously treated RET-fusion NSCLC and previously treated RET-mutant MTC. Based on the early achievement of the enrollment target for the RET-fusion NSCLC cohort, Blueprint Medicines plans to submit an NDA to the FDA for BLU-667 for the treatment of patients with NSCLC previously treated with platinum-based chemotherapy in the first quarter of 2020. Blueprint Medicines continues to expect to submit an NDA to the FDA for BLU-667 for the treatment of patients with RET-mutant MTC previously treated with an approved multi-kinase inhibitor in the first half of 2020.

BLU-554: Advanced hepatocellular carcinoma (HCC)

• Dosed the first patient in China in the ongoing Phase 1 clinical trial of BLU-554 in patients with advanced HCC, under Blueprint Medicines’ collaboration with CStone Pharmaceuticals.

BLU-782: Fibrodysplasia ossificans progressiva (FOP):

First Quarter 2019 Financial Results:

• Cash Position: As of March 31, 2019, cash, cash equivalents and investments were $415.9 million, as compared to $494.0 million as of December 31, 2018. This decrease was primarily related to cash used in operating activities. Cash, cash equivalents and investments as of March 31, 2019 do not include the estimated net proceeds of approximately $327.2 million from the company’s follow-on underwritten public offering of common stock, which closed in April 2019.
• Collaboration Revenues: Collaboration revenues were $0.7 million for the first quarter of 2019, as compared to $1.0 million for the first quarter of 2018. This decrease was primarily due to revenue recorded under the Roche collaboration.
• R&D Expenses: Research and development expenses were $74.3 million for the first quarter of 2019, as compared to $50.0 million for the first quarter of 2018. This increase was primarily due to increased clinical and manufacturing expenses driven by our lead development candidates and increased personnel-related expenses. Research and development expenses included $5.8 million in stock-based compensation expenses for the first quarter of 2019.
• G&A Expenses: General and administrative expenses were $16.6 million for the first quarter of 2019, as compared to $9.9 million for the first quarter of 2018. This increase was primarily due to increased personnel-related expenses, commercial-readiness activities and increased other professional fees. General and administrative expenses included $4.5 million in stock-based compensation expenses for the first quarter of 2019.
• Net Loss: Net loss was $87.4 million for the first quarter of 2019, or a net loss per share of $1.98, as compared to a net loss of $56.5 million for the first quarter of 2018, or a net loss per share of $1.29.

Financial Guidance:

Based on its current plans, Blueprint Medicines expects that its existing cash, cash equivalents and investments, including the estimated net proceeds of approximately $327.2 million from its April 2019 follow-on public offering but 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.
