Summary

The purpose of this study is to determine: 1. The highest dose of the trial intervention that targets neuroendocrine tumors and is tolerated by patients. 2. The highest frequency of dosing of the trial intervention that targets neuroendocrine tumors and is tolerated by patients. 3. The highest dose and frequency of dosing of the trial intervention that targets neuroendocrine tumors with at least the same degree of effectiveness and tolerability as currently available (standard of care) treatments for patients with neuroendocrine tumors.

Interventions

BIOLOGICALSeneca Valley Virus-001 (SVV-001)

SVV-001 will be administered intratumorally as a single dose on Day 1; or as multiple doses on Days 1, 15, 29, 43, 57, and 71. The virus dose levels per SVV-001 treatment are as follows: * 2.2 × 10\^8 Viral Genomes (VG) (starting dose) * 2.2 × 10\^9 VG * 2.2 × 10\^10 VG

DRUGNivolumab

Nivolumab will be administered via intravenous (IV) injection at a dose of 240 mg, once every two weeks starting on Day 15 until Day 85 during SVV-001 therapy. Nivolumab will be administered once every four weeks during the maintenance period for up to 2 years.

DRUGIpilimumab

Ipilimumab will be administered via intravenous (IV) injection at a dose of 1 mg/kg, once every six weeks starting on Day 15 until Day 85 during SVV-001 therapy. Participants will continue on 1 mg/kg ipilimumab IV every 6 weeks for two additional doses or unacceptable toxicity and/or participant withdrawal.
