Research Triangle Park, N.C., April 29, 2019 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq: GTHX), a clinical-stage oncology company, today provided a regulatory update on trilaciclib, a first-in-class myelopreservation agent designed to protect the bone marrow from damage by chemotherapy and improve patient outcomes.
Based on written feedback from its end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) and discussions with European regulatory authorities, the company plans to submit marketing applications in the U.S. and Europe for trilaciclib for myelopreservation in small cell lung cancer (SCLC). These submissions will be based on currently available data from three randomized, double-blind, placebo-controlled SCLC clinical trials, as well as safety data collected across all completed and ongoing clinical trials.
“We are pleased with the feedback from our recent meetings with regulatory authorities. We look forward to continuing a collaborative dialogue regarding the marketing applications, as well as discussing further clinical development of trilaciclib,” said Raj Malik, M.D., Chief Medical Officer. “We believe trilaciclib represents an important advance in the care of SCLC patients. We will also move forward with a robust development program to evaluate trilaciclib in multiple tumor types and chemotherapy regimens.”
G1 will request a pre-New Drug Application (NDA) meeting with the FDA and anticipates it will be scheduled later this year. The company will provide further details regarding the NDA submission and timeline following that meeting. The company plans to submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) subsequent to an NDA filing.
Chemotherapy is an effective and important weapon against cancer. However, chemotherapy does not differentiate between healthy cells and cancer cells and kills both, including important stem cells in the bone marrow that produce white blood cells, red blood cells and platelets. This chemotherapy-induced bone marrow damage is known as myelosuppression. When white blood cells, red blood cells 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.
“In clinical trials, trilaciclib demonstrated the ability to protect bone marrow from chemotherapy damage and meaningfully reduced the need for supportive care interventions, such as G-CSF and transfusions,” said Jared Weiss, M.D., Associate Professor, University of North Carolina Lineberger Comprehensive Cancer Center, and trilaciclib clinical trial investigator. “By providing a proactive approach to reduce myelosuppression, trilaciclib improves the patient experience during chemotherapy treatment, reducing side effects and the need for associated interventions commonly given to treat them.”
Trilaciclib is a first-in-class myelopreservation agent designed to protect the bone marrow from damage by chemotherapy and improve patient outcomes. Trilaciclib is being evaluated in four randomized Phase 2 clinical trials; G1 reported positive results from all these trials in 2018.
