G1 Therapeutics, Inc. (Nasdaq: GTHX), a clinical-stage oncology company, today announced that additional findings from a Phase 2 clinical trial demonstrating the myelopreservation benefits of trilaciclib in 2nd/3rd-line small cell lung cancer (SCLC) patients will be featured as an oral presentation at the upcoming 2019 American Society of Clinical Oncology (ASCO) Annual Meeting. The presentation will take place on June 1, 2019 at 3:00 p.m. CT at the McCormick Place Convention Center in Chicago, Illinois.

Trilaciclib is a first-in-class myelopreservation agent designed to protect the bone marrow from damage by chemotherapy and improve patient outcomes.

“Chemotherapy remains an important treatment in the fight against cancer, however it has serious side effects, including damaging the patient’s bone marrow. We are pleased to present further findings that show the addition of trilaciclib to chemotherapy can protect the bone marrow from damage in those undergoing treatment for SCLC,” said Raj Malik, M.D., Chief Medical Officer and Senior Vice President, R&D. “We look forward to our pre-NDA and pre-MAA meetings later this year with U.S. and European regulatory authorities as we work to bring trilaciclib to market for SCLC patients and continue to explore how trilaciclib may help those with other types of cancer.”

Details on the presentation are listed below and are also available on the 2019 ASCO Annual Meeting website: http://abstracts.asco.org/.
