Testing the Addition of an Immunotherapy Drug, Atezolizumab, to the Usual Chemotherapy Treatment During Radiation Therapy for Superior Sulcus Non-small Cell Lung Cancer
This phase II trial studies the effect of atezolizumab given with usual chemotherapy during
radiation therapy in treating patients with superior sulcus non-small cell lung cancer.
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. Chemotherapy drugs, such as cisplatin, carboplatin, etoposide, paclitaxel and
pemetrexed, 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 beams to kill tumor cells and shrink tumors. Giving atezolizumab with usual
chemotherapy and radiation therapy may lower the chance of the tumor from growing or
spreading.
Description
PRIMARY OBJECTIVE:
I. To compare the pathologic complete response (pCR) by local review between participants
randomized to conventional trimodality therapy, with or without atezolizumab.
SECONDARY OBJECTIVES:
I. To compare event-free survival (EFS) between the arms. II. To compare overall survival
(OS) between the arms. III. To compare surgical resection rate and complete resection (R0)
rate between the arms.
IV. To evaluate progression-free survival (PFS) per Response Evaluation Criteria in Solid
Tumors (RECIST) 1.1 among participants who do not undergo surgical resection, by treatment
arm.
V. To compare the frequency and severity of toxicities between the arms.
ADDITIONAL OBJECTIVES:
I. To bank blood and tissue for future research. II. To evaluate the association between
major pathologic response (MPR), as defined by the International Association for the Study of
Lung Cancer (IASLC), and survival outcomes (OS, PFS).
III. To evaluate the association between pCR by centralized review and survival outcomes (OS,
PFS).
IV. Evaluate the changes in fludeoxyglucose F-18 (FDG)-positron emission tomography (PET)
metrics (e.g., standardized uptake value [SUV] maximum [max], SUVpeak, SUVmax tumor-to-liver,
SUVpeak tumor-to-liver, metabolic tumor volume, total lesion glycolysis, etc.) in
participants randomized to receive trimodality therapy alone or in combination with
atezolizumab and to evaluate the association with pCR.
V. Evaluate the extent to which the changes in diffusion weighted imaging (DWI)-magnetic
resonance imagining (MRI) metrics (e.g., mean apparent diffusion coefficient or apparent
diffusion coefficient [ADC] for the primary tumor, etc.) are associated with pCR in
participants randomized to receive trimodality therapy alone or in combination with
atezolizumab.
VI. Evaluate the extent to which changes in computed tomography (CT) tumor volume,
unidimensional lesion changes per RECIST 1.1 and bidimensional lesion changes per World
Health Organization (WHO) criteria are associated with pCR in participants randomized to
receive trimodality therapy alone or in combination with atezolizumab.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive atezolizumab intravenously (IV) over 30-60 minutes on day 1. Patients
also receive one of the chemotherapy combinations below depending on their previous therapy
and disease. Beginning on the first day of chemotherapy and the first day of cycle 2 of
chemotherapy, patients undergo external beam radiation therapy 5 days per week. Treatment
repeats every 21 days for up to 4 cycles in the absence of disease progression or
unacceptable toxicity. Beginning 21 and 90 days after treatment, patients undergo surgery.
Within 42 days after completion of surgery, patients then receive atezolizumab IV over 30-60
minutes on day 1. Treatment repeats every 21 days for up to 17 cycles in the absence of
disease progression or unacceptable toxicity.
ARM II: Patients receive one of the chemotherapy combinations below depending on their
previous therapy and disease. Beginning on the first day of chemotherapy and the first day of
cycle 2 of chemotherapy, patients also undergo external beam radiation therapy 5 days per
week. Treatment repeats every 21 days for up to 4 cycles in the absence of disease
progression or unacceptable toxicity. Beginning 21 and 90 days after treatment, patients
undergo surgery.
Patients receive one of the chemotherapy combinations:
Cisplatin IV over 2 hours on day 1 and etoposide IV over 30-60 minutes on days 1-3.
Carboplatin IV over 60 minutes on day 1 and etoposide IV over 30-60 minutes on days 1-3.
Paclitaxel IV over 3 hours and carboplatin IV over 60 minutes on day 1.
Patients with non-squamous NSCLC may receive one of the following combinations:
4. Pemetrexed IV over 10 minutes and carboplatin IV over 60 minutes on day 1.
5. Pemetrexed IV over 10 minutes and cisplatin IV over 2 hours on day 1.
After completion of the study treatment, patients are followed up every 6 months for 3 years,
then annually until 6 years from date of Step 1 Randomization.
