Lung Cancer Clinical Trial
Adaptive Radiation Planning for the Reduction of Radiation-Induced Toxicity in Patients With Stage II-IV Non-small Cell Lung Cancer
Summary
This phase II trial studies the effect of adaptive radiation planning in reducing side effects associated with radiation treatment and immunotherapy in patients with stage II-IV non-small cell lung cancer. Prior to radiation, patients undergo simulation, where they are positioned on the treatment table in a manner that can be reproduced each time they receive treatment in order to reach the tumor exactly at the same spot each time. However, a patient's tumor may shrink as they receive radiation, exposing healthy tissue to radiation as well. Adaptive radiation planning involves re-designing a treatment plan at set intervals. The purpose of this study is to see whether establishing set time points through adaptive radiation planning, regardless of whether the doctor notices a significant decrease in tumor size, will reduce some of the side effects associated with radiation treatment and immunotherapy.
Full Description
PRIMARY OBJECTIVE:
I. To evaluate whether implementing set intervals for radiation replanning reduces cardiopulmonary toxicity and preserves healthy lung and heart tissue, with the intention of establishing a new standard treatment modality.
OUTLINE:
Patients undergo computed tomography (CT) stimulation with or without intravenous (IV) contrast over 1.5 hours on days -15 to -1, then undergo standard of care (SOC) chemoradiation on days 1-40. Patients also undergo additional CT scan simulations without IV contrast over 20 minutes each on days 15 and 29.
After completion of study, patients are followed up at 3-12 weeks, and then every 6 months for approximately 2 years.
Eligibility Criteria
Inclusion Criteria:
Written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization for release of personal health information
Histologically or cytological evidence of locally advanced, biopsy-proven, stage II (inoperable), III-or oligometastatic stage IV NSCLC planned to be treated with chemoradiation with concurrent or adjuvant immunotherapy
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Adequate organ and marrow laboratory values for radiation therapy deemed by appropriate the investigator obtained within 14 days prior to registration for protocol therapy
Women of childbearing potential (WOCBP) must obtain a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [HCG]) at day -30 to day 0
Women of childbearing potential must be willing to abstain from heterosexual activity or use an effective method of contraception during the time of the study period
Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year
Exclusion Criteria:
History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the site investigator
Pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial
Active central nervous system (CNS) metastases (if symptomatic or without prior brain imaging, subjects must undergo a head computed tomography [CT] scan or brain magnetic resonance imaging [MRI] within 28 days prior to registration for protocol therapy to exclude brain metastases)
Treatment with any investigational agent within 28 days prior to registration for protocol therapy
Prior chemotherapy, adjuvant therapy, or radiotherapy for lung cancer other than standard concurrent chemoradiation or up to 2 cycles of consolidation therapy
Active second cancers
History of psychiatric illness or social situations that would limit compliance with study requirements
