RESEARCH TRIANGLE PARK, N.C. (GLOBE NEWSWIRE) — G1 Therapeutics, Inc. (Nasdaq: GTHX), a clinical-stage oncology company, today provided a corporate and financial update for the third quarter ended September 30, 2019. Review the full filling here.

“Based on written feedback from the FDA following our pre-NDA meeting in September, we will submit a New Drug Application for myelopreservation in small cell lung cancer. We expect to complete the submission in the second quarter of 2020. Our vision is for trilaciclib to become a new standard of care to mitigate myelosuppression in patients receiving chemotherapy. We are committed to making trilaciclib available to small cell lung cancer patients as quickly as possible, and are executing on a regulatory and development strategy to evaluate the myelopreservation benefits of trilaciclib in the most commonly used chemotherapy regimens. We expect to initiate a Phase 3 trial in colorectal cancer in the second half of 2020. In addition, we will continue to explore trilaciclib in triple-negative breast cancer, where preliminary data has demonstrated a survival benefit.”

– Mark Velleca, M.D., Ph.D., Chief Executive Officer

Third Quarter Regulatory and Clinical Highlights

  • The company plans to submit an NDA for trilaciclib in small cell lung cancer (SCLC) based on written feedback from FDA. Based on written feedback from its pre-NDA meeting with the U.S. Food and Drug Administration (FDA) in September, the company will file an NDA for trilaciclib in SCLC. The company expects to complete the NDA submission in the second quarter of 2020. Earlier this year, trilaciclib received Breakthrough Therapy Designation (BTD) from the FDA based on positive myelopreservation data in SCLC patients from three randomized Phase 2 clinical trials. The BTD program is designed to expedite the development and review of drugs intended for serious or life-threatening conditions. 
  • ESMO presentations: data from Phase 2 clinical trials of trilaciclib in metastatic triple-negative breast cancer (mTNBC) and SCLC and data from Phase 1 clinical trial of G1T48 in ER+, HER2- breast cancer. In an oral presentation on data from a randomized Phase 2 trial of trilaciclib, preliminary overall survival (OS) results demonstrated that women with mTNBC lived significantly longer when receiving trilaciclib and chemotherapy compared with women receiving chemotherapy alone. Data were published simultaneously in The Lancet Oncology. The company also presented updated Phase 2 results in SCLC patients receiving trilaciclib and chemotherapy in combination with Tecentriq® (atezolizumab) (press release here) and the first clinical data on its oral selective estrogen receptor degrader (SERD), G1T48. Preliminary results from the ongoing Phase 1/2a dose-escalation trial of G1T48 in patients with estrogen receptor-positive, HER2-negative (ER+, HER2-) breast cancer showed G1T48 was well tolerated and demonstrated evidence of anti-tumor activity in heavily pre-treated patients. Based on safety and tolerability findings in the Phase 1b portion of this trial, the company selected the 600 mg and 1,000 mg doses of G1T48 for evaluation in the ongoing Phase 2a portion.

Third Quarter 2019 Financial Highlights

  • Cash Position: Cash, cash equivalents and short-term investments totaled $299.9 million as of September 30, 2019, compared to $369.3 million as of December 31, 2018.
  • Operating Expenses: Operating expenses were $34.0 million for the third quarter of 2019, compared to $20.8 million for the third quarter of 2018. GAAP operating expenses include stock-based compensation expense of $4.4 million for the third quarter of 2019, compared to $3.3 million for the third quarter of 2018.
  • Research and Development Expenses: Research and development (R&D) expenses for the third quarter of 2019 were $22.9 million, compared to $15.9 million for the third quarter of 2018. The increase in R&D expense was primarily due to an increase in clinical program costs, costs for manufacturing pharmaceutical active ingredients, and personnel costs due to additional headcount.
  • General and Administrative Expenses: General and administrative (G&A) expenses for the third quarter of 2019 were $11.1 million, compared to $4.9 million for the third quarter of 2018. The increase in G&A expense was largely due to an increase in compensation due to additional headcount, an increase in pre-commercialization activities, an increase in medical affairs costs, and an increase in professional fees and other administrative costs necessary to support our operations.
  • Net Loss: G1 reported a net loss of $32.4 million for the third quarter of 2019, compared to $19.9 million for the third quarter of 2018.
  • 2019 Guidance: The company expects to end the year with $265-$270 million in cash and cash equivalents.

Anticipated Milestones

  • Begin rolling NDA submission for trilaciclib in SCLC in 4Q19, which the company expects to complete in 2Q20; submit Marketing Authorization Application to the European Medicines Agency in 2H20.
  • Initiate clinical trials of trilaciclib in colorectal cancer and TNBC in 2020.
  • Present additional data from the Phase 1b/2a clinical trial of lerociclib + Faslodex® (fulvestrant) at the 2019 San Antonio Breast Cancer Symposium (SABCS) on December 11, 2019.
