G1 Therapeutics to Present Patient-Reported Outcomes (PRO) Data on Trilaciclib At Multinational Association of Supportive Care in Cancer (MASCC) And International Society of Oral Oncology (ISCOO) 2019 Annual Meeting

RESEARCH TRIANGLE PARK, N.C., June 14, 2019 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq: GTHX), a clinical-stage oncology company, today announced that an analysis of patient-reported outcomes (PRO) data from three Phase 2 trials of trilaciclib in small cell lung cancer patients will be featured as an oral presentation at the upcoming Multinational Association of Supportive Care in Cancer (MASCC) and International Society of Oral Oncology (ISCOO) 2019 Annual Meeting. The presentation session will take place on June 21, 2019 at 3:40 p.m. PT in San Francisco.

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

“Chemotherapy is an important tool in fighting cancer, but negatively impacts patients’ quality of life. PRO evaluations in our three small cell lung cancer trials showed that treatment with trilaciclib improved multiple measures of wellbeing for patients receiving chemotherapy compared to placebo,” said Raj Malik, M.D., Chief Medical Officer and Senior Vice President, R&D. “These data provide valuable insight into how the myelopreservation effects of trilaciclib improve the chemotherapy experience for patients, in addition to making chemo safer by reducing side effects and the need for rescue therapies like growth factors and transfusions.”

Details on the presentation are listed below and are also available on the 2019 MASCC/ISCOO 2019 Annual Meeting website: https://masccmeeting.org/2019

About Chemotherapy and Trilaciclib
Chemotherapy is an effective and important treatment against cancer. However, chemotherapy does not differentiate between healthy cells and cancer cells, killing both, including important stem cells in the bone marrow that produce white blood cells (WBCs), red blood cells (RBCs) and platelets. This chemotherapy-induced bone marrow damage is known as myelosuppression. When WBCs, RBCs and platelets become depleted, chemotherapy patients are at increased risk of infection, experience anemia and fatigue, and are at increased risk of bleeding. Myelosuppression often requires the administration of rescue interventions such as growth factors and blood or platelet transfusions, and may also result in chemotherapy dose delays and reductions.

Trilaciclib is a first-in-class myelopreservation agent designed to protect the bone marrow from damage by chemotherapy and improve patient outcomes. G1 expects to submit marketing applications in the U.S. and Europe for trilaciclib for myelopreservation in small cell lung cancer in 2020, and plans to initiate new label expansion trials in 2020.
