Summary
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.
Objectives
PRIMARY OBJECTIVE:
I. To compare overall survival (OS) for patients with LS-SCLC treated with chemoradiation +/- atezolizumab.
SECONDARY OBJECTIVES:
I. To compare progression free survival (PFS) for patients with limited stage small cell lung cancer (LS-SCLC) treated with chemoradiation +/- atezolizumab.
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.
V. 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.
EXPLORATORY OBJECTIVES:
I. 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 Events (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. Patients undergo blood specimen collection throughout the trial.
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. Patients undergo blood specimen collection throughout the trial.
After completion of study treatment, patients are followed up every 3 months for 2 years, then every 6 months for 3 years, then annually thereafter.
Eligibility
- 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 cycle of platinum/etoposide chemotherapy pre-registration (prior to study entry). Study registration must be within 21 days from day 1 of the pre-registration cycle of chemotherapy.
- Patients must have had measurable disease (per Response Evaluation Criteria in Solid Tumors [RECIST], version 1.1) prior to the required pre-registration 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 60 days prior to registration
* CT chest and CT abdomen with IV contrast (unless contraindicated based on kidney function) within 60 days prior to registration; magnetic resonance imaging (MRI) abdomen with IV contrast allowed in place of CT abdomen
** 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
* MRI scan of the brain with contrast (preferred) or CT scan of the brain with contrast (allowable if there is a contraindication with MRI with contrast) within 30 days prior to registration
- Age >= 18
- Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 within 30 days prior to registration
- Absolute neutrophil count (ANC) >= 1,500/cells/mm^3 (prior to pre-registration cycle)
- Platelet count >= 100,000 cells/mm^3 (prior to pre-registration cycle)
- Hemoglobin >= 9 g/dL (prior to pre-registration cycle)
- Total bilirubin =< 1.5 x upper limit of normal (ULN) (prior to pre-registration cycle)
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.0 x ULN (prior to pre-registration cycle)
- Adequate renal function within 30 days prior to registration defined as follows: Creatinine clearance >= 30 mL/min by the Cockcroft-Gault (C-G) equation
- Patients presenting with a pleural effusion will be eligible if thoracentesis is cytologically negative and non-bloody or if pleural fluid is too small a volume to effectively sample by thoracentesis and does not show increased metabolic activity on CT/PET imaging
- Negative serum pregnancy test within 14 days of registration for pre-menopausal women of childbearing potential
- The patient or a legally authorized representative must provide study-specific informed consent prior to study entry
- Hepatitis B/C testing prior to enrollment for patients that have not been tested before. Note: This is required even if the patient has never shown or had symptoms of hepatitis
- Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
