RESEARCH TRIANGLE PARK, N.C., May 09, 2019 (GLOBE NEWSWIRE) — G1 Therapeutics, Inc. (Nasdaq: GTHX), a clinical-stage oncology company, today provided a corporate and financial update for the first quarter ended March 31, 2019.

“Following meetings with regulatory authorities, we have clarity on a path to submitting marketing applications in the U.S. and Europe for trilaciclib based on existing data from our three trials in small cell lung cancer patients,” said Mark Velleca, M.D., Ph.D., Chief Executive Officer. “Our goal is to make trilaciclib available to patients across the globe as quickly as possible and we are encouraged with regulators’ understanding of this new approach to protecting patients from the damaging effects of chemotherapy.”

Raj Malik, M.D., Chief Medical Officer added, “Trilaciclib is the first in a deep pipeline of clinical-stage programs with near-term data readouts expected. We anticipate presenting new data on our next two programs – lerociclib and G1T48 – later this year. Based on promising early results in our Phase 1 clinical trial of G1T48 in ER+ breast cancer, we plan to present proof-of-concept data in the third quarter.”

Clinical, Operational and Executive Team Updates

  • Plan to submit U.S. and European regulatory filings for trilaciclib: The company announced plans to submit marketing applications in the U.S. and Europe for trilaciclib for myelopreservation in small cell lung cancer (SCLC) based on written feedback from its end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) and discussions with European regulatory authorities. G1 intends to file a New Drug Application (NDA) with the FDA in 2020 and submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) subsequent to an NDA filing. Full press release available here.
  • Executive team change: Jennifer Moses, who has been with the company for four years and most recently served as Vice President, Finance, has been appointed Chief Financial Officer. Barclay “Buck” Phillips, who had served as CFO and Senior Vice President, Corporate Development since 2017, departed the company to pursue other interests and opportunities.
  • First investor day presentation: The G1 management team provided a comprehensive overview of the company’s three clinical development programs and outlined the commercialization strategy for trilaciclib. External experts Jeffrey Crawford, M.D., Co-director, Solid Tumor Therapeutics Program, Duke Cancer Institute, and Lowell Hart, M.D., Scientific Director of Research, Florida Cancer Specialists and trilaciclib clinical trial investigator, discussed chemotherapy-induced myelosuppression and trilaciclib’s potential to protect the bone marrow from damage by chemotherapy and improve patient outcomes. The webcast is available on the G1 website here.

First Quarter 2019 Financial Highlights

  • Cash Position: Cash, cash equivalents and short-term investments totaled $347.8 million as of March 31, 2019, compared to $369.3 million as of December 31, 2018.
  • Operating Expenses: Operating expenses were $25.9 million for the first quarter of 2019, compared to $20.7 million for the first quarter of 2018.

  • Research and Development Expenses: Research and development (R&D) expenses for the first quarter of 2019 were $18.1 million, compared to $17.3 million for the first quarter of 2018.

  • General and Administrative Expenses: General and administrative (G&A) expenses for the first quarter of 2019 were $7.8 million, compared to $3.4 million for the first quarter of 2018. The increase in expense was largely due to an increase in compensation due to headcount increase, increase in pre-commercialization activities and an increase in professional fees and other administrative costs necessary to support our operations as a public company.
