Summary

This is a Phase II, single arm, multicenter study designed to evaluate the safety and efficacy of low-dose radiotherapy (LDRT) concurrent cisplatin/carboplatin plus etoposide with atezolizumab in participants who have extensive-stage small cell lung cancer (ES-SCLC) and are chemotherapy-navïe for their extensive-stage disease.

Conditions

• Carcinoma, Small Cell Lung

Interventions

Type	Name	Description
DRUG	Atezolizumab	Atezolizumab will be administered by intravenous 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 an integrated assessment of radiographic and biochemical data, and clinical status.
DRUG	Cisplatin	Cisplatin will be administered as intravenous infusion at a dose of 75 mg per meter squared (75 mg/m\^2) after completion of atezolizumab on Day 1 of each 21-day cycle during the induction phase (Cycles 1-4).
DRUG	Carboplatin	Carboplatin will be administered as intravenous infusion at a dose of area under the concentration-time curve (AUC) of 5 mg/mL/min on Day 1 of each 21-day cycle during the induction phase (Cycles 1-4).
DRUG	Etoposide	Etoposide will be administered intravenously at a dose of 100 mg/m\^2 on Days 1, 2 and 3 of each 21-day cycle during the induction phase (Cycles 1-4).
RADIATION	Thoracic radiation therapy (TRT)	Participants will receive concurrent thoracic radiation therapy (TRT) treatment, in once daily fractions, 3 Gy per fraction, to a target dose of 15 Gy in 5 fractions from Day 1-Day 5 in the first cycle.
