Approximately 705 Adult SCLC patients with Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≤ 2 who have failed one prior platinum-containing line with CTFI ≥ 30 days and controlled asymptomatic Central Nervous System metastases will be enrolled and assigned to each treatment arm.~Central randomization will be implemented; patients will be assigned to each treatment arm at a 1:1:1 ratio.~An Independent Data Monitoring Committee (IDMC) will oversee the conduct of the study. The IDMC should have access to unblinded efficacy and safety data throughout the trial to enable timely and informed judgments about risks and benefits.
Multicenter, open-label, randomized, controlled phase III clinical trial to evaluate and compare the activity and safety of two experimental arms consisting of lurbinectedin as single agent (Group A) or the combination of lurbinectedin with irinotecan (Group B) versus Investigator's Choice (topotecan or irinotecan) as control arm (Group C), in Small-cell Lung Cancer (SCLC) patients who failed one prior platinum-containing line.
