RESEARCH TRIANGLE PARK, N.C., Feb. 28, 2019 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq: GTHX), a clinical-stage oncology company, today reported financial results for the fourth quarter and full-year ended December 31, 2018. The company also highlighted 2018 operational results and upcoming 2019 milestones.
“Data from four randomized Phase 2 trials showed the benefits of trilaciclib across different indications, lines of therapy and chemotherapy regimens,” said Raj Malik, M.D., Chief Medical Officer and Senior Vice President, R&D. “We have scheduled meetings with U.S. and European regulatory authorities in the first half of 2019 to discuss the totality of data and next steps for the development of trilaciclib. We will provide an update on these meetings in the second quarter.”
“We made substantial progress across our three clinical-stage product candidates in 2018. We reported positive results from all four Phase 2 trilaciclib trials, presented proof-of-concept data on lerociclib in breast cancer, initiated a trial of lerociclib in non-small cell lung cancer, and brought our oral selective estrogen receptor degrader G1T48 into the clinic,” said Mark Velleca, M.D., Ph.D., Chief Executive Officer. “These accomplishments will drive a number of important clinical and regulatory milestones in 2019 in the advancement of our pipeline.”
Corporate Highlights
- Reported positive multi-lineage myelopreservation data from three randomized, double-blind, placebo-controlled Phase 2 trials of trilaciclib in small cell lung cancer (SCLC): In the fourth quarter, the company presented additional data from its Phase 2 trial of trilaciclib in combination with chemotherapy in first-line SCLC at the European Society for Medical Oncology (ESMO) 2018 Congress, and reported preliminary data from Phase 2 trials in first-line SCLC in combination with chemotherapy/Tecentriq® (atezolizumab) and second/third-line SCLC in combination with chemotherapy. In these trials, patients receiving trilaciclib showed statistically significant improvements in duration and occurrence of severe neutropenia (primary endpoints) and clinically meaningful reductions in G-CSF administrations and red blood cell transfusions. Treatment was well tolerated and the safety profile of trilaciclib was consistent across the three trials.
- Presented preliminary improved progression-free survival data from randomized Phase 2 trial of trilaciclib in combination with chemotherapy in patients with metastatic triple-negative breast cancer (mTNBC): In December, the company presented data from its Phase 2 trial of trilaciclib in patients with mTNBC at the 2018 San Antonio Breast Cancer Symposium. Preliminary median progression-free survival (PFS) was 5.4 months in the chemotherapy arm, 8.8 months in the chemotherapy and trilaciclib (dosed the day of chemotherapy) arm (hazard ratio 0.52, p=0.0669), and 7.3 months in the chemotherapy and trilaciclib (dosed the day prior to and day of chemotherapy) arm (hazard ratio 0.49; p=0.0546). A combined analysis of trilaciclib-treated patients showed PFS of 5.4 months for the chemotherapy arm and 7.9 months for chemotherapy and trilaciclib (hazard ratio 0.50, p=0.0189). Patients on trilaciclib received more chemotherapy cycles than those in the control arm. The safety profile of trilaciclib was consistent with previously reported trials; no trilaciclib-related serious adverse events were reported.
Anticipated Milestones for 2019
- Meet with U.S. and European regulatory authorities in the first half of 2019 and announce the next steps for trilaciclib development in the second quarter of 2019.
- Initiate additional randomized trials for trilaciclib in the second half of 2019, pending feedback from regulatory authorities.
- Report additional data from all four randomized Phase 2 trilaciclib clinical trials.
- Present additional data from the Phase 1b clinical trial of lerociclib/Faslodex® (fulvestrant) in ER+, HER2- breast cancer in the second half of 2019.
- Present preliminary dose-escalation data from the Phase 1b clinical trial of lerociclib/Tagrisso® (osimertinib) in non-small cell lung cancer in the second half of 2019.
- Present preliminary dose-escalation data from the Phase 1 clinical trial of G1T48, an oral selective estrogen receptor degrader (SERD), in ER+ breast cancer in the second half of 2019.
