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.
In the study, the researchers assessed the impact of trilaciclib versus placebo on subsequent use of supportive therapies-including granulocyte colony stimulating factor (G-CSF), erythropoiesis-stimulating agents (ESAs), and red blood cell transfusions-following chemotherapy treatments for ES-SCLC. The results showed that trilaciclib significantly reduced the duration and occurrence of chemotherapy-induced severe neutropenia and the occurrence of grade 3 or greater chemotherapy-induced anemia, with a corresponding reduction in the use of supportive care therapies to manage these adverse events.
The publication titled, 'Trilaciclib Prior to Chemotherapy Reduces the Usage of Supportive Care Interventions for Chemotherapy-Induced Myelosuppression in Patients with Small Cell
Specifically, the analysis showed that administering trilaciclib prior to chemotherapy: Significantly reduced the occurrence of severe neutropenia-11.4% in the trilaciclib group versus 52.9% in the placebo group (p < 0.0001). with a corresponding reduction in G-CSF use by approximately half in the trilaciclib group compared with placebo
Consistency of treatment effects on occurrence of severe neutropenia with or without concomitant G-CSF use was tested and results indicated that the effect of trilaciclib was consistent regardless of whether or not a G-CSF was administered.
Significantly reduced the occurrence of grade 3/4 anemia compared with placebo-20.3% in the trilaciclib group versus 31.9% in the placebo group (p = 0.0279) with a corresponding reduction of
In a separate analysis, the use of trilaciclib significantly reduced patient hospitalizations due to chemotherapy induced myelosuppression (CIM) or sepsis, with 4.1% of patients hospitalized in the trilaciclib arm versus 13.6% of patients hospitalized in the placebo arm
The findings were derived from a retrospective analysis of pooled data obtained from three randomized, Phase 2 clinical trials of trilaciclib or placebo administered prior to chemotherapy in 242 patients with ES-SCLC. The authors suggest that the pooled data indicate that the administration of trilaciclib prior to chemotherapy has the potential to reduce the burden of CIM on health care systems.
'The results from our analysis show clear myeloprotection benefits associated with the administration of trilaciclib prior to chemotherapy in patients with ES-SCLC,' said
Chemotherapy-induced myelosuppression (CIM) is one of the most common, dose-limiting complications of cancer treatment, and is associated with a range of symptoms that can significantly impact patients' quality of life. The researchers concluded that 'trilaciclib may help to reduce the burden of chemotherapy-induced myelosuppression on patients, caregivers, and health care systems.'

Select Important Safety Information
CONTRAINDICATION
COSELA is contraindicated in patients with a history of serious hypersensitivity reactions to trilaciclib.
WARNINGS AND PRECAUTIONS
Injection-Site Reactions, Including Phlebitis and Thrombophlebitis
COSELA administration can cause injection-site reactions, including phlebitis and thrombophlebitis, which occurred in 56 (21%) of 272 patients receiving COSELA in clinical trials, including Grade 2 (10%) and Grade 3 (0.4%) adverse reactions. Injection-site reactions led to discontinuation of treatment in 3 (1%) of the 272 patients.
Acute Drug Hypersensitivity Reactions
COSELA administration can cause acute drug hypersensitivity reactions, which occurred in 16 (6%) of 272 patients receiving COSELA in clinical trials, including Grade 2 reactions (2%).
Interstitial Lung Disease/Pneumonitis
Severe, life-threatening, or fatal interstitial lung disease (ILD) and/or pneumonitis can occur in patients treated with cyclin-dependent kinases (CDK)4/6 inhibitors, including COSELA, with which it occurred in 1 (0.4%) of 272 patients receiving COSELA in clinical trials.
Embryo-Fetal Toxicity
Based on its mechanism of action, COSELA can cause fetal harm when administered to a pregnant woman. Females of reproductive potential should use an effective method of contraception during treatment with COSELA and for at least 3 weeks after the final dose.
ADVERSE REACTIONS
The most common adverse reactions (?10%) 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. Fatal adverse reactions were observed in 5% of patients receiving COSELA. Fatal adverse reactions for patients receiving COSELA included pneumonia (2%), respiratory failure (2%), acute respiratory failure (
