Non Hodgkin Lymphoma Clinical Trial
Low Dose Radiation as Bridging Therapy in Relapsed B-Cell Non-Hodgkin Lymphoma
The goal of this clinical trial is to learn about treatment for people with B-cell lymphoma that did not respond to treatment or that has gotten worse after treatment. The aim of this trial is to answer the following questions:
If it is realistic to give people radiation treatment before they receive a chimeric antigen receptor (CAR) T-cell treatment for their cancer
If it is safe to give people radiation treatment before they receive a CAR T-cell treatment for their cancer
This is a pilot study to evaluate the feasibility of low-dose radiation therapy in the bridging period between chimeric antigen receptor (CAR) T-cell collection, manufacturing, and infusion (vein-to-vein) in patients with relapsed and refractory aggressive B-cell lymphoma.
Emerging cellular immunotherapies including CAR T-cell therapy have produced remarkable outcomes for this population. The Food and Drug Administration (FDA) has recently approved lisocabtagene maraleucel (liso-cel) for the management of people with relapsed and refractory B-cell lymphoma. Unfortunately, many patients undergoing liso-cel infusion will suffer progression or relapse with devastating consequences. The object of this study is to identify a novel means to enhance liso-cel activity to improve overall outcomes. The investigators hypothesize that the addition of radiation therapy targeting selected sites as bridging therapy prior to lymphodepleting chemotherapy and liso-cel infusion will be effective at improving responses for patients with relapsed and refractory B-cell lymphoma.
Results from this study will provide key justification to expand this therapeutic approach into a larger phase II clinical trial powered to examine the efficacy of this approach.
Biopsy-proven relapsed or progressive diffuse large B-cell lymphoma (DLBCL), high-grade B-cell lymphoma, primary mediastinal B-cell lymphoma, grade 3B follicular lymphoma, or DLBCL arising from indolent lymphoma meeting an FDA-approved (Food and Drug Administration-approved) indication for liso-cel infusion
Presence of disease on imaging including at least one disease site safe for radiation as determined by treating radiation oncologist
Willingness to participate in clinical trial and provide informed consent
Adequate organ function as assessed by standard institution protocols and United States (US) prescribing information label for comorbidities, heart, and lung function to undergo FDA-approved CAR T-cell therapy as determined by institution
Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
Age 19 years or older, there is no upper limit to the age
Subject is unsafe for radiation therapy as determined by investigator and/or radiation oncologist
Diagnosis is primary central nervous system (CNS) lymphoma (secondary CNS lymphoma with additional systemic site is allowed)
Requirement for concurrent high dose methotrexate
Secondary active malignancy that has not been in remission for at least 2 years. This excludes non-melanoma skin cancer, definitively treated stage 1 solid tumor with low risk or recurrence, and curatively treated localized prostate cancer.
