• Trabectedin (Yondelis) is indicated for the treatment of patients with unresectable or metastatic liposarcoma or leiomyosarcoma who received a prior anthracycline-containing regimen. It offers comparable therapeutic efficacy to pazopanib in treating previously treated metastatic synovial sarcoma, with marginal differences in survival outcomes.
• The information was derived from two studies that focused on trabectedin's effectiveness and safety profile compared to another agent, pazopanib.
• In terms of overall survival rates and response rate, there were negligible differences between treatments involving trabectedin and pazopanib. However, a slightly better performance by pazopanib was observed in the overall response rate.
• A crucial safety concern associated with trabectedin therapy is cardiac toxicity. An estimated incidence of cardiac toxicity at 3.4% has been reported, indicating an increase in heart failure cases linked to this drug than previously acknowledged.
• Patients who have had previous exposure to anthracyclines are potentially at elevated risk for developing trabectedin-induced heart failure; hence, meticulous patient selection and monitoring are essential, especially for those with a history of anthracycline treatment.
• Proactive measures such as the implementation of NT-pro-BNP assays have been suggested for early detection and intervention against the potential development of heart failures related to the use of trabectedin (Yondelis).
