Real-world evidence for COSELA

REAL-WORLD STUDY OF COSELA EVALUATING DOSE REDUCTIONS/DELAYS AND HOSPITALIZATIONS

Real-world outcomes of trilaciclib among patients with extensive-stage small cell lung cancer receiving chemotherapy2

A retrospective, observational synthesis of real-world data of COSELA use in patients with ES-SCLC receiving chemotherapy2,a,b

Real-world evidence is observational and may be subject to limitations, including lack of randomization.

Small sample size of the cohort receiving COSELA was a study limitation. COSELA was approved by the FDA in February 2021. Some data were collected before approval, when COSELA was not included in the standard of care. Comparisons between the cohorts that received COSELA and those that did not may therefore reflect evolving treatment practices and access to supportive care over time.

ES-SCLC=extensive-stage small cell lung cancer; LOT1=COSELA initiation before or during first line of therapy; RWD=real-world data.

a This real-world evidence review of COSELA should be interpreted in the context of the limitations of the underlying studies, with the most important ones being lack of comparative effectiveness studies and small sample size.2
b The real-world outcomes associated with COSELA were generally consistent with clinical trials, despite a higher proportion of elderly population, poorer performance status, and variation in timing of initiation of COSELA in real-world studies.2

IMPORTANT SAFETY INFORMATION

CONTRAINDICATION

  • COSELA is contraindicated in patients with a history of serious hypersensitivity reactions to trilaciclib.

To report suspected adverse reactions, contact Pharmacosmos Therapeutics at 1-888-828-0655 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

INDICATION

COSELA 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 (ES-SCLC).

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. Monitor patients for signs and symptoms of injection-site reactions, including infusion-site pain and erythema during infusion. For mild (Grade 1) to moderate (Grade 2) injection-site reactions, flush line/cannula with at least 20 mL of sterile 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP after end of infusion. For severe (Grade 3) or life-threatening (Grade 4) injection-site reactions, stop infusion and permanently discontinue COSELA. 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%). Monitor patients for signs and symptoms of acute drug hypersensitivity reactions. For moderate (Grade 2) acute drug hypersensitivity reactions, stop infusion and hold COSELA until the adverse reaction recovers to Grade ≤1. For severe (Grade 3) or life-threatening (Grade 4) acute drug hypersensitivity reactions, stop infusion and permanently discontinue COSELA.

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. Monitor patients for pulmonary symptoms of ILD/pneumonitis. For recurrent moderate (Grade 2) ILD/pneumonitis, and severe (Grade 3) or life-threatening (Grade 4) ILD/pneumonitis, permanently discontinue COSELA.

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

  • 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 (<1%), hemoptysis (<1%), and cerebrovascular accident (<1%).
  • Permanent discontinuation due to an adverse reaction occurred in 9% of patients who received COSELA. Adverse reactions leading to permanent discontinuation of any study treatment for patients receiving COSELA included pneumonia (2%), asthenia (2%), injection-site reaction, thrombocytopenia, cerebrovascular accident, ischemic stroke, infusion-related reaction, respiratory failure, and myositis (<1% each).
  • Infusion interruptions due to an adverse reaction occurred in 4.1% of patients who received COSELA.
  • The most common adverse reactions (≥10%) were fatigue, hypocalcemia, hypokalemia, hypophosphatemia, aspartate aminotransferase increased, headache, and pneumonia.

DRUG INTERACTIONS

  • COSELA is an inhibitor of OCT2, MATE1, and MATE-2K. Co-administration of COSELA may increase the concentration or net accumulation of OCT2, MATE1, and MATE-2K substrates in the kidney (e.g., dofetilide, dalfampridine, and cisplatin).
