RESEARCH TRIANGLE PARK, N.C., Nov. 04, 2020 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq: ), a clinical-stage oncology company, today provided a corporate and financial update for the third quarter ended September 30, 2020.

“Since I joined G1 in 2014, the company has made tremendous progress in advancing trilaciclib from the lab to receiving Priority Review for our NDA and a PDUFA action date of February 15, 2021. We have built exceptional commercial and medical teams that are prepared for the potential approval of trilaciclib in the first quarter of next year. In addition, we have developed a comprehensive clinical and regulatory strategy to evaluate the use of trilaciclib in other solid tumors, including a registrational trial in metastatic colorectal cancer that is on track to start this quarter,” said Mark Velleca, M.D., Ph.D., Chief Executive Officer. “It has been a privilege to work with the talented team at G1 to accomplish these goals, and I am equally fortunate to be handing the reins to Jack Bailey, our board member and incoming CEO. Jack is a superb leader with extensive experience launching novel therapeutics and managing product development to maximize benefit to patients.”

Regulatory, Clinical and Corporate Highlights

• NDA for trilaciclib in small cell lung cancer (SCLC) accepted by FDA and assigned Priority Review in August 2020. The application was supported by positive data from three randomized clinical trials showing the myelopreservation benefits of trilaciclib in patients with SCLC being treated with chemotherapy. The FDA assigned a Prescription Drug User Fee Act (PDUFA) action date of February 15, 2021 (press release ). Trilaciclib has also received Breakthrough Therapy Designation by the FDA.
• Additional analyses of trilaciclib SCLC trial results presented at North America Conference on Lung Cancer (NACLC). A mini-oral session highlighted analysis of three randomized trials in patients with small cell lung cancer that showed trilaciclib significantly reduced hospitalizations caused by chemotherapy-induced myelosuppression or sepsis.
• Completed enrollment in rintodestrant/palbociclib combination trial in October 2020. The company expects preliminary safety, tolerability and efficacy data from 40 patients enrolled in this Phase 2 trial to be presented in the second quarter of 2021. The trial is comparing a treatment regimen of rintodestrant plus palbociclib (known commercially as Ibrance^®) to fulvestrant plus palbociclib in patients with ER+, HER2- breast cancer.
• CEO succession plan announced in September 2020. Effective January 1, 2021, Mark Velleca, M.D., Ph.D., will transition to the role of senior advisor and continue to serve as a member of the G1 Board of Directors. John (“Jack”) Bailey, a member of the company’s board, has been named as CEO (press release ).

“I’m excited to have the opportunity to lead G1 through its next chapter as a commercial company,” said Jack Bailey, incoming CEO. “Our top priorities remain the successful execution of our launch strategy for trilaciclib in small cell lung cancer and advancing the clinical development of trilaciclib in other tumor types. I’ve gotten to know the team at G1 since joining the board earlier this year, and have been struck by their desire to help patients. It’s a privilege to join this group that shares a common passion for delivering better treatment options to people living with cancer.”

Third Quarter 2020 Financial Highlights and 2020 Guidance

• Cash Position: Cash and cash equivalents totaled $238.3 million as of September 30, 2020, compared to $269.2 million as of December 31, 2019.
• License Revenue: License revenues were $26.6 million for the third quarter of 2020, mostly related to the upfront cash payments from license agreements of $20.0 million and $6.0 million from EQRx, Inc. and Genor Biopharma, Inc., respectively.

• Research and Development Expenses: Research and development (R&D) expenses for the third quarter of 2020 were $17.9 million, compared to $22.9 million for the third quarter of 2019. The decrease in R&D expenses was primarily due to a decrease of $4.6 million in costs for manufacturing active pharmaceutical ingredients, as well as a decrease of $1.6 million in external costs related to discovery and pre-clinical costs development. The decrease is partially offset by an increase of $1.2 million in spend for clinical trials.
• General and Administrative Expenses: General and administrative (G&A) expenses for the third quarter of 2020 were $18.4 million, compared to $11.1 million for the third quarter of 2019. The increase in G&A expenses was largely due to an increase in compensation due to additional headcount, increase in pre-commercialization activities, and an increase in professional fees and other administrative costs necessary to support our commercial operations.
• Net Loss: G1 reported a net loss of $11.7 million for the third quarter of 2020, compared to $32.4 million for the third quarter of 2019.
