What this trial studies

This phase I trial investigates the safety and optimal dosage of a modified vesicular stomatitis virus (VSV-hIFNβ-NIS) combined with immunotherapy agents ipilimumab and cemiplimab in patients with various forms of T-cell lymphoma. The study aims to determine the maximum tolerated dose while monitoring side effects and assessing the virus's ability to selectively target and kill cancer cells. Patients will undergo imaging scans and may have biopsies to evaluate treatment response throughout the study. Follow-up will occur for up to one year after treatment completion to monitor for disease progression.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with relapsed peripheral T-cell lymphoma or specific histologies such as anaplastic large cell lymphoma and mycosis fungoides.

Not a fit: Patients with active liver disease beyond Child Pugh class A or those with other significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel and effective treatment option for patients with relapsed or refractory T-cell lymphoma.

How similar studies have performed: While the use of oncolytic viruses in cancer treatment is an emerging field, this specific combination of VSV with immunotherapy is novel and has not been extensively tested in prior studies.

Exclusion Criteria:

* Availability of and patient acceptance of curative therapy
* Uncontrolled infection
* Active tuberculosis or hepatitis, or chronic hepatitis
* Any of the following prior therapies:

  * Chemotherapy (IMIDs, alkylating agents, proteosome inhibitors) =\< 2 weeks prior to registration
  * Immunotherapy (monoclonal antibodies) =\< 4 weeks prior to registration
