    G1 Therapeutics Presents Two Posters at ISPOR Describing the Estimated Economic Impact of Treating Myelosuppression Among Patients with Extensive-Stage Small Cell Lung Cancer May 17, 2021 - A Cost-Benefit Model of Administration of COSELATM (trilaciclib) Prior to Chemotherapy Estimates Measurable Per-Patient Cost Savings - - Myelosuppression Poses a Substantial Burden on the Health Care System Among Patients with Small Cell Lung Cancer, According to an Analysis of SEER-Medicare Data - RESEARCH TRIANGLE PARK, N.C., May 17, 2021 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq: GTHX), a commercial-stage oncology company, today presented two scientific posters at the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) describing the estimated economic impact of treating myelosuppression among patients with extensive-stage small cell lung cancer. The posters are available in the scientific publications section of the G1’s website. COSELA was approved by the U.S. Food and Drug Administration on February 12, 2021 to decrease the incidence of chemotherapy-induced myelosuppression in adult patients when administered prior to a platinum/etoposide-containing regimen or topotecan-containing regimen for ES-SCLC. Cost-Benefit Analysis of Trilaciclib for the Prevention of Chemotherapy-Induced Myelosuppression in Extensive-Stage Small Cell Lung Cancer (Deniz, B. et al.) (poster) The first poster details a cost-benefit model estimating the economic value from a U.S. commercial payer perspective of using COSELA™ (trilaciclib) prior to chemotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC). According to the model, the estimated potential total cost savings per patient is $15,006 – savings that are based on a projected reduction in myelosuppressive adverse events (AEs) and their associated treatment costs.

(Nasdaq: GTHX), a commercial-stage oncology company, today announced that the Company has initiated PRESERVE 3, a Phase 2, randomized, open-label study of COSELA™ (trilaciclib) administered with first-line platinum-based chemotherapy and the immune checkpoint inhibitor avelumab maintenance therapy in patients with untreated, locally advanced or metastatic urothelial carcinoma (mUC). Myeloprotection and anti-tumor efficacy endpoints are being assessed in this study. Initial results of this study are expected in the second half of 2022. “Bladder cancer is unfortunately common and the five-year survival rate for metastatic urothelial carcinoma has not changed in the last 25 years, highlighting the need for new and well tolerated therapies specifically tailored for immune sensitive tumors like this,” said Raj Malik, M.D., Chief Medical Officer at G1 Therapeutics. “While chemotherapy followed by avelumab maintenance therapy has proven to be a meaningful step forward for the 1L treatment of patients with mUC, patients may not receive the maximal benefit for a variety of reasons. These Phase 2 data will be instructional and important to evaluate the benefit of adding COSELA to this regimen, and if positive, would be quickly followed by a Phase 3 registrational trial.” Patient recruitment in Preserve 3 is now underway.

  • G1 Therapeutics Announces Initiation of Phase 1B/2 Clinical Trial of G1T38 in Combination with Tagrisso for EGFR-Mutant Non-Small Cell Lung Cancer
    G1 Therapeutics Announces Initiation of Phase 1b/2 Clinical Trial of G1T38 in Combination with Tagrisso for EGFR-Mutant Non-Small Cell Lung Cancer April 16, 2018 RESEARCH TRIANGLE PARK, N.C., April 16, 2018 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq:GTHX), a clinical-stage oncology company, today announced that it has initiated a Phase 1b/2 clinical trial assessing G1T38, its oral CDK4/6 inhibitor, in combination with Tagrisso® (osimertinib) in people with EGFR-mutant (EGFRm) non-small cell lung cancer (NSCLC). AstraZeneca (LON: AZN) is providing Tagrisso for this trial under a non-exclusive clinical trial collaboration agreement. “G1T38 inhibits tumor cell growth, providing a rationale for combining it with other targeted therapies, including EGFR-TKI inhibitors such as Tagrisso. In a prior Phase 1a trial, G1T38 had no dose-limiting toxicities and was well tolerated with no impact on liver or cardiovascular function, presenting evidence of a favorable safety and tolerability profile for combination therapy,” said Raj Malik, M.D., Chief Medical Officer and Senior Vice President, R&D of G1 Therapeutics. “Despite advances in care, lung cancer remains the leading cause of cancer death globally. Non-small cell lung cancer represents the majority of lung cancers, and there is a significant need for new treatment options that improve outcomes for people with this disease.” The open-label trial is expected to enroll approximately 145 participants in two parts: a safety, pharmacokinetic and dose-finding portion (Part 1); and a subsequent randomized portion (Part 2). Primary outcome measures include safety and tolerability, identifying a recommended Phase 2 dose and progression-free survival (PFS).

  • Myeloprotection
    For people with small cell lung cancer who are receiving certain types of chemotherapy MYELOPROTECTION: (my-low-proh-TEK-shun) A big word that means: helping protect the blood-forming cells in your bone marrow from a harmful side effect of chemotherapy called “bone marrow suppression.” COSELA™ (trilaciclib) can help protect these cells and lower your risk of bone marrow suppression. INDICATION COSELA is a prescription medicine used to help reduce the occurrence of low blood cell counts caused by damage to bone marrow from chemotherapy. COSELA is used to treat adults taking certain chemotherapies (platinum/etoposide or topotecan) for extensive-stage small cell lung cancer.
