G1 Therapeutics Presents Two Posters at ISPOR Describing the Estimated Economic Impact of Treating Myelosuppression Among Patients with Extensive-Stage Small Cell Lung Cancer

– A Cost-Benefit Model of Administration of COSELA^TM (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. The authors attributed this cost saving, in part, to data from previous trials indicating that use of COSELA prior to chemotherapy was associated with fewer myelosuppressive AEs: 0.6 AEs per patient with COSELA compared to 2.7 myelosuppressive AEs per patient without COSELA.  

Overall, the authors suggested that the model indicates that COSELA could be an economically favorable innovation when addressing the incidence of myelosuppression in patients with ES-SCLC receiving a platinum/etoposide-containing chemotherapy regimen.

Trends in Prevalence, Treatment Patterns, Myelosuppression, and Burden on the Health Care System Among Patients with Small Cell Lung Cancer: A SEER-Medicare Analysis (Epstein, R. et al.) (poster)

The second poster quantifies the impact of treatment-induced myelosuppression among Medicare patients diagnosed with SCLC, thereby contributing to the growing body of scientific evidence demonstrating the significant health burden, economic toll, and health-related quality-of-life effects of chemotherapy-induced myelosuppression. The presented findings — among the first to evaluate healthcare utilization in a SEER Medicare-linked data set of SCLC patients — provided an epidemiologic assessment quantifying the real-world prevalence, treatment patterns and healthcare burden of myelosuppression prior to the availability of COSELA.

Among the findings of this SEER Medicare epidemiologic study:

• Nearly three-quarters of chemotherapy-treated patients experienced anemia during the timeframe studied (2012 to 2015);
• Neutropenia was reported in 45.2% of chemotherapy-treated patients overall;
• Thrombocytopenia was reported in 27.0% of chemotherapy-treated patients overall;
• Pancytopenia was reported in 24.4% of patients overall; and
• During the same period, 74.3% of chemotherapy-treated patients experienced at least one inpatient admission associated with myelosuppression.

“Chemotherapy remains a cornerstone of treatment for SCLC, and chemotherapy-induced myelosuppression is a frequent complication that may manifest as neutropenia, anemia, and/or thrombocytopenia,” said Marc Chioda, PharmD, G1’s Vice President of Medical Affairs and co-author of both posters. “These analyses add to the data that help clarify the potential positive financial impact of COSELA usage and the projected real-world economic value of COSELA. Together, these data suggest that use of COSELA should be a favorable economic strategy in the first line of therapy compared with standard care.”

About Small Cell Lung Cancer

In the United States, approximately 30,000 small cell lung cancer patients are treated annually. SCLC, one of the two main types of lung cancer, accounts for about 10% to 15% of all lung cancers. SCLC is an aggressive disease and tends to grow and spread faster than NSCLC. It is usually asymptomatic; once symptoms do appear, it often indicates that the cancer has spread to other parts of the body. About 70% of people with SCLC will have cancer that has metastasized at the time they are diagnosed. The severity of symptoms usually increases with increased cancer growth and spread. From the time of diagnosis, the general 5-year survival rate for people with SCLC is 6%. The five-year survival rates for limited-stage (the cancer is confined to one side of the chest) SCLC is 12% to 15%, and for extensive stage (cancer has spread to the other lung and beyond), survival rates are less than 2%. Chemotherapy is the most common treatment for ES-SCLC.

About COSELA (trilaciclib) for Injection

Indication
COSELA (trilaciclib) was approved by the U.S. Food and Drug Administration on February 12, 2021. COSELA (trilaciclib) is indicated 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 extensive-stage small cell lung cancer.

Important Safety Information
COSELA is contraindicated in patients with a history of serious hypersensitivity reactions to trilaciclib.

Warnings and precautions include injection-site reactions (including phlebitis and thrombophlebitis), acute drug hypersensitivity reactions, interstitial lung disease (pneumonitis), and embryo-fetal toxicity.

The most common adverse reactions (>10%) were fatigue, hypocalcemia, hypokalemia, hypophosphatemia, aspartate aminotransferase increased, headache, and pneumonia.
