Intravenous Vesicular Stomatitis Virus in Patients With Peripheral T-cell Lymphoma

May 26, 2026 updated by: Mayo Clinic

MC1684 Phase I Trial of Systemic Administration of Vesicular Stomatitis Virus Genetically Engineered to Express NIS and Human Interferon, in Patients With Relapsed or Refractory Multiple Myeloma, Acute Myeloid Leukemia, Lymphomas, or Histiocytic/Dendritic Cell Neoplasms

This phase I trial studies the best dose and side effects of recombinant vesicular stomatitis virus (VSV) carrying the human (h) sodium iodide symporter (NIS) and Interferon (IFN) beta (β) genes (VSV-hIFNβ-NIS) in combination with cemiplimab in patients with T-cell lymphoma. A virus, called VSV-hIFNβ-NIS, which has been changed in a certain way, may be able to kill cancer cells without damaging normal cells. Immunotherapy with ipilmumab and cemiplimab may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread.

Study Overview

Detailed Description

PRIMARY OBJECTIVE: To determine the maximum tolerated dose (MTD) of VSV-hIFNβ-NIS in combination with cemiplimab in patients with T-cell lymphoma [Group E].

Patients undergo computed tomography (CT) scan, position emission tomography (PET) scan throughout the study. Patients may undergo tumor biopsy, bone marrow biopsy and blood sample collection throughout the study.

After completion of study treatment, patients are followed up for 28 days, and then every 3 months for up to 1 year or until progressive disease, then every 6 months for 1 year.
