Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Experimental Arm A: treatment by lurbinectedin and durvalumab; Patients with with platinum sensitive extensive stage small-cell lung cancer (SCLC) which failed one prior platinum-containing regimen will be treated by the association of lurbinectedin and durvalumab	Drug: Association of lurbinectedin and durvalumab; A treatment cycles consists of 3 weeks (i.e. 21 days). Lurbinectedin will be administered by intravenous infusion on Day 1 every 3 weeks. Durvalumab will be administered by intravenous infusion on Day 1 every 3 weeks.
Other: Standard Arm B: treatment by carboplatin and etoposide; Patients with with platinum sensitive extensive stage small-cell lung cancer (SCLC) which failed one prior platinum-containing regimen will be treated by the association of carboplatin and etoposide	Drug: Association of carboplatin and etoposide; Treatment will be administered on a 21-days cycle basis up to a maximum of 6 cycles. Carboplatin will be administered by intravenous infusion on Day 1 every 3 weeks. Etoposide will be administered by intravenous infusion on Day 1-3 every 3 weeks

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Assessment of the antitumor activity of lurbinectedin combined with durvalumab	Antitumor activity will be assessed in terms of of 6-month progression-free rate (rate of complete or partial responses or stable disease more than 24 weeks, as per RECIST v1.1 criteria) after blinded centralized radiological review	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
