CAMBRIDGE, Mass.--(BUSINESS WIRE)--Nov. 8, 2018-- Magenta Therapeutics (NASDAQ: MGTA), a clinical-stage biotechnology company developing novel medicines to bring the curative power of bone marrow transplant to more patients, today reported financial results and business highlights for the third quarter ended September 30, 2018.

“Over the third quarter of 2018, Magenta has continued its progress across the portfolio and remains well funded and on track for our 2020 vision of three programs moving forward in the clinic in multiple indications,” said Jason Gardner, D.Phil., chief executive officer and president, Magenta Therapeutics. “We look forward to sharing important data updates on our stem cell expansion, mobilization and targeted conditioning programs at ASH this year as we work to build a fully integrated company with the singular goal of allowing more patients to receive curative cell therapies.”

Recent Business Highlights:

Nine Clinical and Preclinical Abstracts Accepted for Presentation at the ASH Annual Meeting: Magenta announced on November 1st, 2018 that nine abstracts from the Company and its collaborators were accepted for presentation at the ASH annual meeting in December 2018. The abstracts cover the breadth of Magenta’s integrated portfolio of programs and include preliminary clinical data from the Company’s Phase 2 study of cell therapy MGTA-456 in patients with inherited metabolic disorders.

Continued to Strengthen Robust Intellectual Property Position: Magenta’s first U.S. patent, directed to dosage regimens of mobilization therapy MGTA-145 and plerixafor, was issued in August 2018. The Company’s second U.S. patent was issued for the C200 conditioning program in October 2018, with claims directed to methods of treatment using an anti-CD117-amatoxin antibody-drug conjugate (ADC). For the C100 targeted patient preparation program, an Australian patent application was allowed with claims directed to methods of treatment using an anti-CD45-amatoxin ADC.

Financial Results:

Cash Position: Cash and cash equivalents as of September 30, 2018, were $159.7 million compared to $51.4 million on December 31, 2017. The increase is primarily driven by net proceeds from the $52.2 million Series C preferred stock financing completed in April 2018, and net proceeds of $89.9 million from Magenta’s IPO completed in June 2018. Magenta anticipates that its cash and cash equivalents will be sufficient to fund operations and capital expenditures through at least the first quarter of 2020 on the Company’s current business plan.

Research and Development Expenses: Research and development (R&D) expenses were $11.4 million in the third quarter of 2018, compared to $5.2 million for the same period in 2017. The increase was largely due to increased preclinical costs, toxicology studies and manufacturing to support our mobilization program, the advancement of the MGTA-456 Phase 2 clinical trial, continued progression of the Company’s pipeline and increased costs associated with the growth of the Company.

General and Administrative Expenses: General and administrative (G&A) expenses were $5.3 million for the third quarter of 2018, compared to $1.8 million for the same period in 2017. The increase was largely due to increased G&A personnel and facility costs associated with the growth of the Company.

Net Loss: Net loss was $16 million for the third quarter of 2018, compared to net loss of $6.9 million for the same period in 2017.
