National Cancer Institute (NCI)·interventional·Posted Jan 22, 2019·Updated Jun 26, 2026

In Brief

A Phase 3 clinical trial evaluating 3-Dimensional Conformal Radiation Therapy, Atezolizumab, and 7 other interventions for Limited Stage Lung Small Cell Carcinoma and 3 related conditions. Active but no longer recruiting, targeting 544 participants across 543 sites in 2 countries.

Detailed Summary

This phase III trial studies how well chemotherapy and radiation therapy (chemoradiation) with or without atezolizumab works in treating patients with limited stage small cell lung cancer. Drugs used in chemotherapy, such as etoposide, cisplatin, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving chemoradiation with or without atezolizumab may work better in treating patients with limited stage small cell lung cancer.

Arms & Interventions

Arm I (chemotherapy, radiation therapy)active_comparator

Patients receive etoposide IV on days 1-3 and cisplatin IV or carboplatin IV on day 1. Cycles repeat every 21 days for 3 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo 3D-CRT or IMRT BID for approximately 3 weeks or QD for approximately 6-7 weeks in the absence of disease progression or unacceptable toxicity. Patients undergo blood specimen collection throughout the trial.

Arm II (chemotherapy, radiation therapy, atezolizumab)experimental

Patients receive treatment as in Arm I. Patients also receive atezolizumab IV over 30-60 minutes on day 1 or 2 of each chemotherapy cycle. Cycles repeat every 3 weeks for 17 cycles (1 year) in the absence of disease progression or unacceptable toxicity. Patients undergo blood specimen collection throughout the trial.
