FDA Approves G1 Therapeutics COSELATM (trilaciclib): The First and Only Myeloprotection Therapy to Decrease the Incidence of Chemotherapy-Induced Myelosuppression
- COSELA is the only FDA-approved therapy that helps proactively deliver multilineage myeloprotection to patients with extensive-stage small cell lung cancer being treated with chemotherapy -
- Myeloprotective efficacy of COSELA resulted in reductions in the incidence and duration of severe neutropenia, and impacted anemia and the need for rescue interventions such as growth factors and red blood cell transfusions -
- G1 will host conference call Tuesday, February 16, 2021 at 8:00 a.m. ET -
RESEARCH TRIANGLE PARK, N.C., February 12, 2021 G1 Therapeutics, Inc. (Nasdaq: GTHX), a commercial-stage oncology company, today announced that the U.S. Food and Drug Administration (FDA) has approved COSELATM (trilaciclib) for injection 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 (ES-SCLC). It is the first and only therapy designed to help protect bone marrow (myeloprotection) when administered prior to treatment with chemotherapy. COSELA is expected to be commercially available through G1s specialty distributor partner network in early March.
The approval of trilaciclib (COSELA) is an important advance in the treatment of patients with extensive-stage small cell lung cancer receiving chemotherapy, said Dr. Jeffrey Crawford, Geller Professor for Research in Cancer in the Department of Medicine and Duke Cancer Institute. The most serious and life-threatening side effect of chemotherapy is myelosuppression, or damage to the bone marrow, resulting in reduced white blood cells, red blood cells and platelets. Chemotherapy-induced myelosuppression may lead to increased risks of infection, severe anemia, and/or bleeding. These complications impact patients quality of life and may also result in chemotherapy dose reductions and delays. To date, approaches have included the use of growth factor agents to accelerate blood cell recovery after the bone marrow injury has occurred, along with antibiotics and transfusions as needed. By contrast, trilaciclib provides the first proactive approach to myelosuppression through a unique mechanism of action that helps protect the bone marrow from damage by chemotherapy. In clinical trials, the addition of trilaciclib to extensive-stage small cell lung cancer chemotherapy treatment regimens reduced myelosuppression and improved clinical outcomes. The good news is that these benefits of trilaciclib will now be available for our patients in clinical practice.
Chemotherapy is an effective and important weapon against cancer. However, chemotherapy does not differentiate between healthy cells and cancer cells. It kills both, including important hematopoietic stem and progenitor cells (HSPCs) in the bone marrow that produce white blood cells (immune cells that help fight infection), red blood cells (cells that carry oxygen from the lungs to the tissues), and platelets (cells that prevent bleeding from cancer, surgeries, chronic diseases, and injuries). This chemotherapy-induced bone marrow damage, known as myelosuppression, can lead to increased risk of infection, anemia, thrombocytopenia, and other complications. Myeloprotection is a novel approach of protecting HSPCs
1
in the bone marrow from chemotherapy-induced damage. This approach can help reduce some chemotherapy-related toxicity, making chemotherapy safer and more tolerable, while also reducing the need for reactive rescue interventions.
Chemotherapy is the most effective and widely used approach to treating people diagnosed with extensive-stage small cell lung cancer; however, standard of care chemotherapy regimens are highly myelosuppressive and can lead to costly hospitalizations and rescue interventions, said Jack Bailey, Chief Executive Officer at G1 Therapeutics. COSELA will help change the chemotherapy experience for people who are battling ES-SCLC. G1 is proud to deliver COSELA to patients and their families as the first and only therapy to help protect against chemotherapy-induced myelosuppression.
COSELA is administered intravenously as a 30-minute infusion within four hours prior to the start of chemotherapy and is the first FDA-approved therapy that helps provide proactive, multilineage protection from chemotherapy-induced myelosuppression. The approval of COSELA is based on data from three randomized, placebo-controlled trials that showed patients receiving COSELA prior to the start of chemotherapy had clinically meaningful and statistically significant reduction in the duration and severity of neutropenia. Data also showed a positive impact on red blood cell transfusions and other myeloprotective measures. The trials evaluated COSELA in combination with carboplatin/etoposide (+/- the immunotherapy atezolizumab) and topotecan chemotherapy regimens. Approximately 90% of all patients with ES-SCLC will receive at least one of these regimens during the course of their treatment.
The majority of adverse reactions reported with COSELA were mild to moderate in severity. The most common adverse reactions (³10%) were fatigue, hypocalcemia, hypokalemia, hypophosphatemia, aspartate aminotransferase increased, headache, and pneumonia. Serious adverse reactions occurred in 30% of patients receiving COSELA. Serious adverse reactions reported in >3% of patients who received COSELA included respiratory failure, hemorrhage, and thrombosis. Grade 3/4 hematological adverse reactions occurring in patients treated with COSELA and placebo included neutropenia (32% and 69%), febrile neutropenia (3% and 9%), anemia (16% and 34%), thrombocytopenia (18% and 33%), and leukopenia (4% and 17%), respectively.
Quite often, people diagnosed with extensive-stage small cell lung cancer rely on chemotherapy to not only extend their lives, but also to acutely alleviate their symptoms, said Bonnie J. Addario, lung cancer survivor, co-founder and board chair of the Go2 Foundation for Lung Cancer. Unfortunately, the vast majority will experience chemotherapy-induced side effects, resulting in dose delays and reductions, and increased utilization of healthcare services. G1 shares our organizations goal to improve the quality of life of those diagnosed with lung cancer and to transform survivorship among people living with this insidious disease. We are thrilled to see new advancements that can help improve the lives of those living with small cell lung cancer.
Approximately 30,000 small cell lung cancer patients are treated in the United States annually. G1 is committed to helping patients with extensive-stage small cell lung cancer in the U.S. gain access to treatment with COSELA. For more information on access and affordability programs, patients and providers should call the G1toOne support center at 833-G1toONE (833-418-6663) from 8:00 a.m. to 8:00 p.m. Eastern time.

G1 received Breakthrough Therapy Designation from the FDA in 2019 based on positive data in small cell lung cancer patients from three randomized Phase 2 clinical trials. As is common with breakthrough-designated products that receive priority review, G1 will conduct certain post-marketing activities, including in vitro drug-drug interaction and metabolism studies, and a clinical trial to assess impact of trilaciclib on disease progression or survival in patients with ES-SCLC with chemotherapy-induced myelosuppression treated with a platinum/etoposide-containing or topotecan-containing regimen with at least a two year follow up. G1 intends to initiate the post-approval clinical trial in 2022.
Webcast and Conference Call
The management team will host a webcast and conference call at 8:00 a.m. ET on Tuesday, February 16, 2021 to discuss the FDA approval of COSELA (trilaciclib). The live call may be accessed by dialing 866-763-6020 (domestic) or (210) 874-7713 (international) and entering the conference code: 6195528.

COSELA (trilaciclib) Co-Promotion Agreement with Boehringer Ingelheim
In June 2020, G1 announced a three-year co-promotion agreement with Boehringer Ingelheim for COSELA in small cell lung cancer in the U.S. and Puerto Rico. G1 will lead marketing, market access and medical engagement initiatives for COSELA. The Boehringer Ingelheim oncology commercial team, well-established in lung cancer, will lead sales force engagement initiatives. G1 will book revenue and retain development and commercialization rights to COSELA and pay Boehringer Ingelheim a promotional fee based on net sales. The three-year agreement does not extend to additional indications that G1 is evaluating for trilaciclib. Press release details of the G1/ Boehringer Ingelheim agreement can be found here.
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.

The Burden of Chemotherapy Myelosuppression can have a significant negative impact on clinical outcomes, healthcare costs, and overall patient quality of life An unavoidable consequence of chemo that impacts patient safety, healthcare system costs and QoL MYELOSUPPRESSION Hospitalizations and unscheduled patient care Chemotherapy dose reductions and delays THROMBOCYTOPENIA Risk of bleeding Platelet transfusions ANEMIA Fatigue RBC transfusions and ESA rescue NEUTROPENIA Risk of infection G-CSF use (associated bone pain) Increased healthcare costs HEMATOLOGIC EVENT: CONSEQUENCE: RESPONSE:
Reduced Incidence of Multi-lineage Myelosuppression in 1L‒3L ES-SCLC1 (pooled data across our 3 randomized placebo-controlled double-blind trials) Clinical Results: COSELA consistently demonstrated meaningful reductions in hematologic adverse events across multiple randomized ES-SCLC studies P<0.0001 P=0.089 P=0.028 P=0.0067 1. Weiss et al., 2020 American Society of Clinical Oncology (ASCO), Abstract #384. COSELA Meaningfully Reduces Myelosuppression in ES-SCLC
COSELA Can Drive Payor/Hospital Savings Average total annual cost per patient without a grade 3/4 hematologic event: Average Total Annual Cost Per Patient with a Grade 3/4 Hematologic Event (Jan 2016 – Dec 2019)1 Neutropenia $131,047 Anemia $95,954 Thrombocytopenia $90,053 Payor Impact: COSELA’s ability to reduce the severe hematologic consequences of chemotherapy expected to result in a budget-neutral to savings-positive impact $67,802 Cost savings from less hematologic events largely driven by: Reduced interventions (e.g., G-CSF, ESA) Fewer required transfusions Fewer complications and hospitalizations 1.
