A Phase III, Open-Label Study of Maintenance Lurbinectedin in Combination With Atezolizumab Compared With Atezolizumab in Participants With Extensive-Stage Small-Cell Lung Cancer

NCT05091567

Active Not RecruitingPhase 3

Sponsor: Hoffmann-La Roche

Conditions: Small-Cell Lung Cancer

Interventions: Atezolizumab, Lurbinectedin, Carboplatin, Etoposide

Countries: United States, Belgium, Germany, Greece, Hungary, Italy, Mexico, Poland

Study GO43104 is a Phase III, randomized, open-label, multicenter study of lurbinectedin in combination with atezolizumab compared with atezolizumab alone administered as maintenance therapy in participants with extensive-stage small-cell lung cancer (ES-SCLC) after first-line induction therapy with carboplatin, etoposide, and atezolizumab. The study consists of 2 phases: an induction phase and a maintenance phase. Participants need to have an ongoing response or stable disease per the Response Evaluation Criteria in Solid Tumor (RECIST) v1.1 criteria after completion of 4 cycles of carboplatin, etoposide, and atezolizumab induction treatment in order to be considered for eligibility screening for the maintenance phase. Eligible participants will be randomized in a 1:1 ratio to receive either lurbinectedin plus atezolizumab or atezolizumab in the maintenance phase.

* Histologically or cytologically confirmed ES-SCLC
* Adequate hematologic and end-organ function to receive 4 cycles of induction treatment with carboplatin, etoposide and atezolizumab
* Measurable disease, as defined by RECIST v1.1

* History of idiopathic pulmonary fibrosis, organizing pneumonia, drug induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computed tomography (CT) scan
* Treatment with investigational therapy within 28 days prior to enrollment

Inclusion Criteria for the Maintenance Phase:

* ECOG PS of 0 or 1
* Ongoing response or stable disease per RECIST 1.1 after 4 cycles of induction therapy

Exclusion Criteria for the Maintenance Phase:

* Presence or history of CNS metastases
* Receiving consolidative chest radiation
* Severe infection within 2 weeks prior to randomization into the maintenance
* Treatment with therapeutic oral or IV antibiotics at the time of randomization
