Phase 2 Trial of Nivolumab in Epstein-Barr Virus (EBV)-Positive Lymphoproliferative Disorders and EBV-Positive Non-Hodgkin Lymphomas
National Cancer Institute (NCI)
Summary
Background: The drug Nivolumab has been approved to treat some cancers. Researchers want to see if it can slow the growth of other cancers. They want to study its effects on cancers that may have not responded to chemotherapy or other treatments. Objectives: To see if Nivolumab slows the growth of some types of cancer or stops them from getting worse. To test the safety of the drug. Eligibility: People 12 and older who have Epstein-Barr Virus (EBV)-positive lymphoproliferative disorders or EBV-positive non-Hodgkin lymphomas with no standard therapy Design: Participants will be screened with: Medical history Physical exam Blood and urine tests CAT scan of the chest, abdomen, and pelvis Tumor and bone marrow biopsies (sample taken) Magnetic resonance imaging scan of the brain Lumbar puncture (also known as spinal tap) Positron emission tomography/computed tomography scan with a radioactive tracer Every 2 weeks, participants will get Nivolumab by vein over about 1 hour. They will also have: Physical exam Blood and pregnancy tests Review of side effects and medications During the study, participants will repeat most of the screening tests. They may also have other biopsies. After stopping treatment, participants will have a visit every 3 months for 1 year. Then they will have a visit every 6 months for years 2-5, and then once a year. They will have a physical exam and blood tests. ...
Description
BACKGROUND: * Epstein-Barr virus (EBV) is a chronic viral infection associated with a heterogeneous group of lymphoproliferative disorders (LPD) and non-Hodgkin lymphomas (NHL). * The shared pathobiology of EBV-positive LPDs and NHLs includes a defect in host mechanisms of immune tolerance and immunosurveillance. * Programmed death-1 (PD-1) is a surface protein present on T cells, B cells, and macrophages that serves a co-inhibitory role to negatively regulate immune responses * PD-1 and its ligands, PD-L1 and PD-L2, are overexpressed in EBV-positive lymphoproliferative disorders and are mark…
