Clinical Trial of Lurbinectedin as Single-agent or in Combination With Irinotecan Versus Topotecan or Irinotecan in Patients With Relapsed Small-cell Lung Cancer (LAGOON)

PHASE3RECRUITING

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.

Study details:

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 and pretreated 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.

What is the study measuring?

Primary outcome

Primary Outcome Measure	Primary Outcome Description	Primary Outcome Time Frame
Overall survival	Overall survival (OS) will be calculated from the date of randomization to the date of death or last contact (in this case, survival will be censored on that date).	From the date of randomization to the date of death or last contact, up to 39 months

Secondary outcome

Secondary Outcome Measure	Secondary Outcome Description	Secondary Outcome Time Frame
Progression-free survival by IRC (Independent Review Committee)	Progression-free survival (PFS) will be calculated from the date of randomization to the date of documented progression per RECIST v.1.1 (Progressive disease is declared when there is an increase in sum of target disease ≥ 20%) or death (regardless of the cause of death). If the patient receives further antitumor therapy, withdraws from the study, or is lost to follow-up before progressive disease (PD), PFS will be censored at the date of last evaluable tumor assessment before the date of subsequent antitumor therapy.	From the date of randomization to the date of progressive disease, death or last tumor assessment or further anticancer treatment, up to 39 months
Progression-free survival by IA (Investigator Assessment)	Progression-free survival (PFS) will be calculated from the date of randomization to the date of documented progression per RECIST v.1.1 (Progressive disease is declared when there is an increase in sum of target disease ≥ 20%) or death (regardless of the cause of death). If the patient receives further antitumor therapy, withdraws from the study, or is lost to follow-up before progressive disease (PD), PFS will be censored at the date of last evaluable tumor assessment before the date of subsequent antitumor therapy.

Overall response rate by IRC	Overall response rate (ORR) will be the percentage of patients with complete or partial response as the best response obtained in any evaluation according to RECIST v.1.1.

Duration of response by IRC	Duration of response (DoR) will be calculated from the date of first documentation of response per RECIST v.1.1 (complete or partial response, whichever occurs first) to the date of documented PD or death. Progressive disease is declared when there is an increase in sum of target disease ≥ 20%, stable disease when the change is \> -30% and ≤ 20%, partial response when there is a decrease in sum of target disease ≥ 30%, and complete response when all lesions have disappeared or all lesions have disappeared and all nodal disease is \< 10 mm each.	From the date of first documentation of complete or partial response to the date of documented progression disease, death or last contact, up to 39 months
