About This Trial

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 ipilimumab and 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.

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Peripheral T Cell Lymphoma, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 21 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
