About
This phase II trial studies the side effects of radiation therapy followed by atezolizumab in treating patients with stage II or III non-small cell lung cancer. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more cancer cells and have fewer side effects. 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. The purpose of this study is to test the safety and effectiveness of radiation therapy followed by atezolizumab and find out what side effects, if any, it has on patient's non-small cell lung cancer.
Full description
PRIMARY OBJECTIVE:
I. To evaluate the rate of grade 3-5 treatment-related adverse events (TRAEs) in patients who are not candidates for surgery or concurrent chemoradiation and who have either performance status 0-2 and stage II or performance status 2 and stage III non-small cell lung cancer (NSCLC), treated with hypofractionated thoracic radiotherapy followed by atezolizumab.
SECONDARY OBJECTIVES:
I. To evaluate response rate (confirmed and unconfirmed, complete and partial by Response Evaluation Criteria in Solid Tumors [RECIST] 1.1) from Registration Step 2 in the subset of patients with measurable disease.
II. To evaluate response rate (confirmed and unconfirmed, complete and partial by RECIST 1.1) during radiation therapy in the subset of patients with measurable disease.
III. To evaluate progression free survival (PFS) from Registration Step 2 by RECIST 1.1.
IV. To evaluate overall survival (OS) from Registration Step 2. V. To evaluate the frequency and severity of toxicities.
ADDITIONAL OBJECTIVE:
I. To bank blood and archival tissue for future research.
OUTLINE:
RADIATION THERAPY: Patients undergo hypofractionated radiation therapy 5 days per week over 3 weeks for 15 fractions in the absence of disease progression or unacceptable toxicity.
CONSOLIDATION: Patients receive atezolizumab intravenously (IV) over 30-60 minutes on day 1 of each cycle. Cycles repeat every 21 days for up to 12 months (maximum of 17 cycles) in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) scan and may undergo magnetic resonance imaging (MRI) throughout the study, as well as blood sample collection on study.
After completion of study treatment, patients are followed up at 6 weeks, every 12 months for the 1 year, then every 6 months until 3 years after study start.

Inclusion and exclusion criteria
Inclusion Criteria:
- REGISTRATION STEP 1: Participants must have pathologic (cytological or histological) proof of non-small cell lung cancer (NSCLC)
- REGISTRATION STEP 1: Participants must have stage III NSCLC with Zubrod performance status of 2 or stage II NSCLC with Zubrod performance status of 0-2
- REGISTRATION STEP 1: Participants must not be candidates for surgical resection in the opinion of the treating investigator. Participants whose disease was previously resected must have experienced local or regional recurrence at least 12 months after resection
- REGISTRATION STEP 1: Participants must not be candidates for concurrent chemoradiation in the opinion of the treating investigator
- REGISTRATION STEP 1: Participants must have measurable or non-measurable disease documented by CT or MRI. Measurable disease must be assessed within 28 days prior to Registration Step 1. Non-measurable disease must be assessed within 42 days prior to Step 1 registration. The CT from a combined positron emission tomography (PET)/CT may be used only if it is of diagnostic quality. All known sites of disease must be assessed and documented on the Baseline Tumor Assessment Form (RECIST 1.1)
- REGISTRATION STEP 1: Participants must have an MRI or CT scan of the brain with contrast within 28 days prior to Registration Step 1
- REGISTRATION STEP 1: Participants' disease must fit within the radiation constraints in the opinion of a local radiation oncologist
- REGISTRATION STEP 1: Participants may have received prior treatment for their lung cancer, including surgery, chemotherapy, targeted agents, and/or radiation treatment. At least 12 months must have elapsed since last treatment
- REGISTRATION STEP 1: Participants may have had prior radiation therapy as long as the irradiated area does not overlap with the radiation field targeted for this study
- REGISTRATION STEP 1: Participants must have recovered from any adverse effects of prior major surgery to the satisfaction of the treating physician. Biopsies and central IV access placement are not considered major surgery
- REGISTRATION STEP 1: Absolute neutrophil count (ANC) >= 1500/mcl (obtained within 28 days prior to Registration Step 1)
- REGISTRATION STEP 1: Platelet count >= 100,000/mcl (obtained within 28 days prior to Registration Step 1)
- REGISTRATION STEP 1: Hemoglobin >= 9 grams/dL (obtained within 28 days prior to Registration Step 1)
- REGISTRATION STEP 1: Total bilirubin =< 1.5 x institutional upper limit of normal (IULN) (obtained within 28 days prior to Registration Step 1)
- REGISTRATION STEP 1: Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x IULN (obtained within 28 days prior to Registration Step 1)
- REGISTRATION STEP 1: Serum creatinine =< 1.5 x IULN OR measured or calculated creatinine clearance >= 40 mL/min (obtained within 28 days prior to Registration Step 1)
- REGISTRATION STEP 1: Participants must have percent predicted diffusing capacity of the lungs for carbon monoxide (DLCO) of at least 40% documented within 90 days prior to Registration Step 1
- REGISTRATION STEP 1: Patient must not have had a prior history of interstitial lung disease or > grade 2 (Common Terminology Criteria for Adverse Events [CTCAE] version 5) pneumonitis
- REGISTRATION STEP 1: Participants must not have active autoimmune disease requiring therapy within the past 6 months
- REGISTRATION STEP 1: Participants must not have an active infection requiring therapy
- REGISTRATION STEP 1: Participants must be ≥ 18 years old
- REGISTRATION STEP 1: Participants must not be pregnant or nursing because atezolizumab has not been studied in pregnant or nursing women and the mechanism of action is expected to cause fetal harm. Women/men of reproductive potential must have agreed to use an effective contraceptive method while on protocol treatment and for five months after last dose of atezolizumab. A woman is considered to be of "reproductive potential" if she has had menses at any time in the preceding 12 consecutive months. In addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation. However, if at any point a previously celibate patient chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures
