What's the purpose of this trial?

This phase I trial studies the best dose and side effects of the VSV-hIFNβ-NIS vaccine with or without cyclophosphamide and combinations of ipilimumab, nivolumab, and cemiplimab in treating patients with multiple myeloma, acute myeloid leukemia or lymphoma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory).

This trial is currently open and accepting patients.

What will happen during the trial?

VSV-IFNβ-NIS is a modified version of the vesicular stomatitis virus (also called VSV). This virus can cause infection and when it does it typically infects pigs, cattle, or horses but not humans. The VSV used in this study has been altered by having two extra genes (pieces of DNA) added. The first gene makes a protein called NIS that is inserted into the VSV. NIS is normally found in the thyroid gland (a small gland in the neck) and helps the body concentrate iodine. Having this additional gene will make it possible to track where the virus goes in the body (which organs). The second addition is a gene for human interferon beta (β) or hIFNβ. Interferon is a natural anti-viral protein, intended to protect normal healthy cells from becoming infected with the virus. VSV is very sensitive to the effect of interferon. Many tumor cells have lost the capacity to either produce or respond to interferon. Thus, interferon production by tumor cells infected with VSV-IFNβ-NIS will protect normal cells but not the tumor cells. The VSV with these two extra pieces is referred to as VSV-IFNβ-NIS. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill cancer cells. It may also lower the body's immune response. Immunotherapy with monoclonal antibodies, such as ipilimumab, nivolumab, and cemiplimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving VSV-IFNβ-NIS with or without cyclophosphamide and combinations of ipilimumab, nivolumab, and cemiplimab may be safe and effective in treating patients with recurrent peripheral T-cell lymphoma.

PRIMARY OBJECTIVE:

I. To determine the maximum tolerated dose (MTD) of recombinant vesicular stomatitis virus-expressing human interferon beta and sodium-iodide symporter (VSV-hIFNβ-NIS) in different treatment regimens (alone [Group A, F, G] in combination with ruxolitinib [Group B] and in combination with cyclophosphamide [Group C]) in patients with relapsed/refractory multiple myeloma, acute myeloid leukemia, T and B-cell lymphoma, or histiocytic/dendritic cell neoplasms; in combination with ipilimumab and nivolumab in patients with multiple myeloma [Group D] and in combination with ipilimumab and cemiplimab in patients with T-cell lymphoma [Group E].

SECONDARY OBJECTIVES:

I. To determine the safety profile of VSV-hIFNβ-NIS (alone and in combination).

II. To estimate clinical response rate of VSV-hIFNβ-NIS (alone and in combination) in patients with relapsed/refractory multiple myeloma, acute myeloid leukemia, T and B-cell lymphoma, or histiocytic/dendritic cell neoplasms overall and by disease type.

III. To estimate progression-free and overall survival of VSV-hIFNβ-NIS (alone and in combination) in patients with relapsed/refractory multiple myeloma, acute myeloid leukemia, T and B-cell lymphoma, or histiocytic/dendritic cell neoplasms overall and by disease type.

CORRELATIVE OBJECTIVES:

I. To determine the time course of viral gene expression and virus elimination, and the biodistribution of virally infected cells at various times points after infection with VSV-hIFNβ-NIS using planar and single photon emission computed tomography (SPECT)/computed tomography (CT) or fluorine F 18 tetrafluoroborate (TFB)-positron emission tomography (PET) imaging.

II. To assess virus replication, viremia, viral shedding in urine and respiratory secretions, and virus persistence after systemic administration of VSV-hIFNβ-NIS.

III. To characterize the pharmacodynamics (PD) of VSV-IFNβ-NIS by way of measuring serum interferon-β and also vesicular stomatitis virus (VSV)-real time (RT)-polymerase chain reaction (PCR) of VSV-IFNβ-NIS.

IV. Assess CD8+ T cell (both general and VSV-IFNβ-NIS specific) and natural killer (NK) cell responses.

V. Gene expression analysis pre- and post-virotherapy. VI. Assess presence of VSV in tumor and normal tissues subsequent to administration of intravenous (IV) VSV-IFNβ-NIS.

VII. To identify the best dose of VSV-hIFNβ-NIS in the regimen being evaluated based on activity observed in the correlative measures described above in those dose levels identified as tolerable.

OUTLINE: This is a dose escalation study of VSV-hIFNβ-NIS followed by a dose-expansion study. Patients are assigned to 1 of 7 groups.

GROUP A: Patients receive VSV-hIFNβ-NIS IV over 30 minutes on day 1 and ruxolitinib PO on days 2-6 in the absence of disease progression or unacceptable toxicity. Patients also undergo PET/CT during screening and as clinically indicated thereafter, bone marrow aspiration and biopsy, tumor or lymph node biopsy, and collection of blood, buccal cells, and urine throughout the study. Patients may also receive optional TFB IV and undergo optional PET scan, as well as optional biopsy of imaging positive area on study.

GROUP B: Patients receive ruxolitinib PO on days -1 to 9 and VSV-hIFNβ-NIS IV over 30 minutes on day 1 in the absence of disease progression or unacceptable toxicity. Patients also undergo PET/CT during screening and as clinically indicated thereafter, bone marrow aspiration and biopsy, tumor or lymph node biopsy, and collection of blood, buccal cells, and urine throughout the study. Patients may also receive optional TFB IV and undergo optional PET scan, as well as optional biopsy of imaging positive area on study.

GROUP C: Patients receive ruxolitinib PO on days -1 to 9, VSV-hIFNβ-NIS IV over 30 minutes on day 1, and cyclophosphamide IV over 2 hours on day 2 in the absence of disease progression or unacceptable toxicity. Patients also undergo PET/CT during screening and as clinically indicated thereafter, bone marrow aspiration and biopsy, tumor or lymph node biopsy, and collection of blood, buccal cells, and urine throughout the study.

After completion of VSV-hIFNβ-NIS, patients are followed up on days 15 and 29, at 6 weeks, and then every 3 months until 1 year or until disease progression, whichever is longer, followed by every 6 months until a total of 2 years after registration.
