Phase I Trial to Evaluate the Safety and Efficacy of Intratumoral and Intravenous Injection of Vesicular Stomatitis Virus Expressing Human Interferon Beta, and Tyrosinase Related Protein 1 (VSV-IFNb-TYRP1) in Patients With Metastatic Ocular Melanoma and Previously Treated Patients With Unresectable Stage III/IV Cutaneous Melanoma

This phase I trial studies the side effects and best dose of a modified virus called
VSV-IFNbetaTYRP1 in treating patients with stage III-IV melanoma. The vesicular stomatitis
virus (VSV) has been altered to include two extra genes: human interferon beta (hIFNbeta),
which may protect normal healthy cells from becoming infected with the virus, and TYRP1,
which is expressed mainly in melanocytes (specialized skin cell that produces the protective
skin-darkening pigment melanin) and melanoma tumor cells, and may trigger a strong immune
response to kill the melanoma tumor cells.

PRIMARY OBJECTIVES:

I. To determine the safety profile and maximum tolerated dose (MTD) of recombinant vesicular
stomatitis virus-expressing interferon-beta and tyrosinase related protein 1
(VSV-IFNbeta-TYRP1) therapy when administered by intravenous (IV) and intratumoral (IT)
injection in patients with previously treated metastatic melanoma.

SECONDARY OBJECTIVES:

I. To gather preliminary data on tumor response rate and progression-free survival time of
VSV-IFNbeta-TYRP1 intravenous and intratumoral therapy among patients with metastatic
malignant melanoma.

CORRELATIVE OBJECTIVES:

I. To determine the pharmacokinetic (PK) profile of VSV-IFNbeta-TYRP1 in patients by
measurement of viremia in the blood using reverse transcriptase polymerase chain reaction
(RT-PCR) for VSV-N ribonucleic acid (RNA).

II. To characterize the pharmacodynamics (PD) of VSV-IFNbeta-TYRP1 by measuring serum
interferon-beta.

III. To determine if there is viral shedding (mouthwash, buccal swab, and urine) before and
after viral treatment at different time points.

IV. Assess fresh pre- and post-treatment tumor biopsy samples for viral RNA, viral protein by
immunohistochemistry (IHC), infectious virus recovery, infiltrating immune cells.

V. Assess transcriptome of fresh pre- and post-treatment tumor biopsy samples. VI. Assess
exome of fresh peripheral blood lymphocytes (PBL) and fresh tumor samples pre-VSV treatment
for neoantigen profiling.

VII. Assess changes in cytokine levels and immune cell profile in peripheral blood and tumor
samples, pre and post viral treatment.

VIII. Assess if there is an increase in the amount of VSV and melanoma antigen, specifically
TYRP1, reactive IFN-gamma secreting T cells by intracellular staining intracellular cytokine
(ICS) and enzyme-linked immunosorbent spot (ELISpot) assays.

OUTLINE: This is a dose-escalation study. Patients are assigned to 1 of 2 groups.

GROUP A: Patients receive recombinant vesicular stomatitis virus-expressing interferon-beta
and tyrosinase related protein 1 intratumorally (IM) and intravenously (IV) over 30-60
minutes 2-4 hours later on day 1.

GROUP B: Patients receive recombinant vesicular stomatitis virus-expressing interferon-beta
and tyrosinase related protein 1 IM and IV over 30-60 minutes 2-4 hours later on day 1. Cycle
1 continues for 28 days, with subsequent cycles repeating every 21 days in the absence of
disease progression or unacceptable toxicity.

After completion of study treatment, patients in Group A are followed up at 42 days. Patients
in Group B are followed up at 28 days, every 3 months until progressive disease, and then
every 6 months for a maximum of 5 years after study registration.
