Before the FDA approved lurbinectedin for SCLC that progressed on or after platinum-based chemotherapy in 2020, topotecan was the sole second-line option associated with hematological toxicities and modest efficacy. Lurbinectedin received conditional approval in Korea in September 2022 for metastatic SCLC progression, with the same indications. Real-world data on its efficacy remains scarce owing to its recent implementation.Patients and Methods: Patients with metastatic SCLC who progressed on or after first-line therapy (n = 51) at Yonsei Cancer Center, Seoul, received lurbinectedin at 3.2 mg/m². Efficacy data, including tumor response, progression, survival, and demographics, were recorded.Results: A total of fifty-one patients received lurbinectedin between April 2023 and March 2024, with thirty-four patients being eligible for the assessment. At diagnosis, approximately one-third of the patients were female, 3% had a poor performance status with an Eastern Cooperative Oncology Group Performance Score (ECOG PS ≥ 2), and the median age was 68. Most patients (80%) had extensive disease. Overall objective response rate (ORR) and disease control rate (DCR) were 20% and 47%, respectively. The median progression-free survival (PFS) was 2.8 months, and the median overall survival (OS) was 3.3 months. Never smokers showed prolonged OS compared with current/former smokers (Smokers; 3.0 vs 7.3 months). Common adverse effects were nausea (53%), loss of appetite (24%), general weakness (18%), anemia (29%), neutropenia (12%), dizziness (6%), alopecia (6%), thrombocytopenia (3%), and pneumonia (3%). Overall, 24% of the patients experienced grade ≥ 3 adverse events (AEs), with the most common being anemia (9%) and neutropenia (9%).Conclusion: Real-world data suggest that lurbinectedin is a viable option for patients with SCLC who have progressed on or after platinum-based chemotherapy.Keywords: SCLC, lurbinectedin, real-world evidence, second line
