• Lurbinectedin (Zepzelca) is indicated for the treatment of adult patients with metastatic small cell lung cancer (SCLC) who have experienced disease progression on or after platinum-based chemotherapy.
• Two studies were reviewed to gather information about this medication. The first study evaluated various treatments for relapsed SCLC, while the second compared lurbinectedin to other second-line treatments specifically in platinum-sensitive patients.
• According to these studies, many current treatments show uncertain clinical potential due to issues such as lack of randomization and small sample sizes. This observation highlights a significant unmet need within the field of relapsed SCLC treatment.
• Lurbinectedin demonstrates significant survival benefits over oral and IV topotecan and platinum re-challenge in treating metastatic SCLC. It also has a favorable safety profile according to hazard ratios indicating a reduced risk of death compared to these treatments.
• Specifically among platinum-sensitive patients, lurbinectedin appears superior based on its effectiveness and safety profile. This suggests that it may fill a critical gap for this subgroup within the challenging therapeutic area of relapsed SCLC treatment.
• Despite promising results from phase 2 data regarding certain medications like tyrosine kinase inhibitors (TKIs), more phase 3 trials are needed, especially comparing lurbinectedin with standard treatments, in order to better define its position in the treatment paradigm for SCLC.
