G1 Therapeutics to Present Additional Data from Randomized Phase 2 Trial of Trilaciclib in Combination with Etoposide/Carboplatin at European Society for Medical Oncology (ESMO) 2018 Congress
New data analyses demonstrate multi-lineage benefits of trilaciclib on neutrophils, red blood cells and lymphocytes in treatment of first-line small cell lung cancer
RESEARCH TRIANGLE PARK, N.C., Oct. 09, 2018 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq: GTHX), a clinical-stage oncology company, today announced that new data from its randomized Phase 2 clinical trial of trilaciclib in combination with etoposide/carboplatin for treatment of first-line small cell lung cancer (SCLC) will be presented at the European Society for Medical Oncology (ESMO) 2018 Congress, being held in Munich, Germany. The company reported topline data from this trial in March 2018 showing robust myelopreservation benefits. Additional data from this trial have been selected for a poster discussion session on October 21. A second poster with new data focused specifically on the impact of trilaciclib on immune system function, including preservation of T cell subsets such as activated CD8+ T cells and an increased CD8+/regulatory T cell ratio in peripheral blood compared to placebo, will be presented on October 20.
"These Phase 2 trial data are consistent with previously reported topline findings and demonstrate the multi-lineage myelopreservation benefits of trilaciclib across neutrophils, red blood cells and lymphocytes for patients receiving chemotherapy," said Raj Malik, M.D., Chief Medical Officer and Senior Vice President, R&D. "Our analyses of trilaciclib-related immune response supports the hypothesis that trilaciclib has the potential to improve efficacy of chemotherapy/immune checkpoint inhibitor combinations. Chemotherapy/checkpoint combinations are emerging as standard of care in multiple tumor types, and trilaciclib may offer both myelopreservation and survival benefits when added to these regimens. We expect preliminary myelopreservation data from our Phase 2 clinical trial combining trilaciclib with chemotherapy and the checkpoint inhibitor Tecentriq® (atezolizumab) for the treatment of first-line small cell lung cancer later this year."
Details on the presentations are listed below. Both presentations will be available on the Publications page of the company’s website following their presentation at ESMO.

Trilaciclib is a first-in-class myelopreservation therapy designed to preserve hematopoietic stem and progenitor cell function, as well as immune system function, during chemotherapy. Trilaciclib is a short-acting intravenous CDK4/6 inhibitor administered prior to chemotherapy and has the potential to significantly improve treatment outcomes.
Trilaciclib is being evaluated in four randomized Phase 2 clinical trials. In March 2018, G1 announced positive Phase 2 data showing myelopreservation benefits in newly diagnosed, treatment-naive small cell lung cancer (SCLC) patients (NCT02499770). Additional results from this trial will be reported at the European Society for Medical Oncology (ESMO) 2018 Congress being held October 19-23. The company plans to report data from three other randomized Phase 2 trials in 2018: a trial in combination with chemotherapy and Tecentriq® in first-line SCLC, (NCT03041311), a trial in combination with chemotherapy in previously treated SCLC (NCT02514447), and a trial in combination with chemotherapy in triple-negative breast cancer (NCT02978716).
