Description

Inclusion Criteria:

• Histologically or cytologically confirmed ES-SCLC per the Veterans Administration Lung Study Group (VALG) staging system

• Life expectancy > 12 weeks
• No prior systemic treatment for ES-SCLC
• Patients who have received prior chemoradiotherapy for limited-stage SCLC must have been treated with curative intent and experienced a treatment-free interval of at least 6 months since last chemotherapy, radiotherapy, or chemoradiotherapy cycle from diagnosis of ES-SCLC
• Patients where thoracic radiotherapy (consolidation RT) is clinically indicated could be enrolled providing they receive RT between the completion of induction phase and the beginning of maintenance phase
• Patients with Paraneoplastic syndromes can be enrolled if an autoimmune origin can be excluded
• Adequate hematologic and end organ function
• Negative human immunodeficiency virus (HIV) test at screening
• Negative hepatitis B surface antigen (HBsAg) test at screening
• Negative total hepatitis B core antibody (HBcAb) test at screening, or positive total HBcAb test followed by a negative hepatitis B virus (HBV) DNA test at screening
• Negative hepatitis C virus (HCV) antibody test at screening, or positive HCV antibody test followed by a negative HCV RNA test at screening. The HCV RNA test will be performed only for patients who have a positive HCV antibody test.

(4) Patient has no ongoing requirement for corticosteroids as therapy for CNS disease. Anticonvulsant therapy at a stable dose is permitted. Metastases are limited to the cerebellum or the supratentorial region. (5) There is no evidence of interim progression between completion of CNS directed therapy and initiation of study treatment.

• Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures. Patients with indwelling catheters are allowed regardless of drainage frequency.
• Uncontrolled or symptomatic hypercalcemia
• History of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computerized tomography (CT) scan. History of radiation pneumonitis in the radiation field (fibrosis) is permitted.
• Active tuberculosis
• Significant cardiovascular disease within 3 months prior to initiation of study treatment, unstable arrhythmia, or unstable angina
• Major surgical procedure other than for diagnosis within 4 weeks prior to initiation of study treatment, or anticipation of need for a major surgical procedure during the study
• History of malignancy other than SCLC within 5 years prior to screening, with the exception of malignancies with a negligible risk of metastasis or death, such as adequately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, localized prostate cancer, ductal carcinoma in situ, or Stage I uterine cancer
• Prior allogeneic stem cell or solid organ transplantation treatment, or anticipation of need for such a vaccine during atezolizumab treatment or within 5 months after the final dose of atezolizumab
• Current treatment with anti-viral therapy for HBV
• Treatment with investigational therapy within 28 days prior to initiation of study treatment

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Atezolizumab + Carboplatin + Etoposide; Participants will receive intravenous infusions of atezolizumab 1200 milligrams (mg) in combination with carboplatin to achieve an initial target area under the concentration-time curve (AUC) of 5 milligrams per milliliter per minute (mg/mL/min), followed by intravenous infusion of etoposide 100 milligrams per square meter (mg/m^2) on days 1 through 3 of each cycle during the induction phase (21-day cycle for four/six cycles). On Days 2 and 3, participants will receive etoposide alone. After the induction phase, participants will begin maintenance therapy with atezolizumab every 3 weeks until PD, unacceptable toxicity, loss of clinical benefit or study termination by the Sponsor.

Drug: Atezolizumab; Atezolizumab will be administered by IV infusion at a fixed dose of 1200 mg on Day 1 of each 21-day cycle until unacceptable toxicity or loss of clinical benefit as determined by the investigator. After the induction phase, participants will begin maintenance therapy with atezolizumab every 3 weeks.; Other Names: MPDL3280A, RO5541267, Tecentriq; Drug: Carboplatin; Carboplatin will be administered after completion of atezolizumab by IV infusion over 30-60 minutes to achieve an initial target AUC of 5 mg/mL/min (Calvert formula dosing) with standard anti-emetics per local practice guidelines.; Drug: Etoposide; Etoposide will be administered by IV infusion over 60 minutes following carboplatin administration, during the induction phase on Day 1 through 3 of each cycle. On Days 2 and 3, patients will receive etoposide alone.
