A Study of Chemoradiation With or Without Experimental Atezolizumab For Limited Stage Small Cell Lung Cancer
This phase II/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.
Limited Stage Small Cell Lung Cancer (LS-SCLC): A Phase II/III Randomized Study of Chemoradiation Versus Chemoradiation Plus Atezolizumab
- To compare progression free survival (PFS) for patients with limited stage small cell lung cancer (LS-SCLC) treated with chemoradiation +/- atezolizumab. (Phase II) II. To compare overall survival (OS) for patients with LS-SCLC treated with chemoradiation +/- atezolizumab. (Phase III)
- To compare progression free survival (PFS) for patients with limited stage small cell lung cancer (LS-SCLC) treated with chemoradiation +/- atezolizumab. (Phase III) II. To determine overall response rate (ORR), rates of local control, and distant metastases free survival with chemoradiation +/- atezolizumab.
III. To characterize immune mediated and non-immune mediated toxicity from chemoradiotherapy plus atezolizumab.
IV. To compare quality of life, as measured by the Functional Assessment of Cancer Therapy-Trial Outcome Index (FACT-TOI), for patients undergoing chemoradiation +/- atezolizumab.
- To evaluate the quality-adjusted survival, using scores from the 5-level EuroQol 5-dimensional questionnaire (EQ-5D-5L), of chemoradiation +/- atezolizumab for patients with LS-SCLC.
VI. To characterize fatigue, as measured by the Patient-Reported Outcomes Measurement Information System (PROMIS), following chemoradiation +/- atezolizumab.
VII. To determine the association of blood based tumor mutational burden (bTMB) and tissue-based tumor mutational burden (tTMB) with clinical outcome.
- To collect biospecimens at baseline, Day 1 and 3 months after the end of chemoradiotherapy, to allow for future analyses.
II. To characterize patient-reported symptomatic toxicities measured by the Patient-Reported Outcomes - Common Terminology Criteria for Adverse Evens (PRO-CTCAE).
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive etoposide intravenously (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 three-dimensional conformal radiation therapy (3D-CRT) or intensity-modulated radiation therapy (IMRT) twice daily (BID) for approximately 3 weeks or once daily (QD) for approximately 6-7 weeks in the absence of disease progression or unacceptable toxicity.
ARM II: 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.
After completion of study treatment, patients are followed up every 3 months for 2 years, then every 6 months for 3 years.

Open to people ages 18 years and up
- Pathologically (histologically or cytologically) proven diagnosis of limited stage small cell lung cancer (Stage Tx, T1-T4, N0-3, M0, American Joint Committee on Cancer [AJCC] staging, 8th edition [Ed.]), within 60 days prior to registration
- Patients must have received one pre-registration cycle of platinum/etoposide chemotherapy prior to study entry, with study registration required within 21 days from day 1 of the pre-registration cycle of chemotherapy and protocol treatment designed to begin 21 days after. If patient has not recovered from pre-registration cycle chemotherapy toxicities, then an additional 14 days is permitted
- Patients must have had measurable disease (per Response Evaluation Criteria in Solid Tumors [RECIST], version 1.1) prior to the required cycle of platinum/etoposide chemotherapy
- Minimal staging requirements include:
- History/physical examination within 30 days prior to registration
- Positron emission tomography (PET)/computed tomography (CT) scan for staging within 45 days prior to registration
- CT chest/abdomen with IV contrast (unless contraindicated based on kidney function) within 45 days prior to registration - this can be obtained as part of PET/CT if CT imaging is of diagnostic quality
- Note: If contrast allergy exists, premedication per institutional guidelines should be performed prior to obtaining CT with contrast. The only exception to this is a documented life-threatening allergy
