Ph1 Administration of VSV-IFNβ-NIS Monotherapy and in Combination With Avelumab in Pts With Refractory Solid Tumors

Summary

This is a three-part open label phase 1 study designed to determine the safety profile, MTD, PK and tumor and biomarker response after IT or IV administration of a single dose of VSV-IFNβ-NIS, or combined IT followed by IV VSV-IFNβ-NIS, with or without IV avelumab every two weeks, in patients with refractory advanced/metastatic solid tumors.

Detailed description

The study consists of three parts: a single ascending dose escalation of IT VSV-IFNβ-NIS monotherapy, a monotherapy IV regimen selection phase and an expansion phase, designed to explore the safety and efficacy of the chosen monotherapy regimen alone or in combination with avelumab in patients with metastatic colorectal cancer. Monotherapy will also be explored in patients with pheochromocytoma and NET. Patients are required to have at least 1 measurable lesion per RECIST 1.1, and in the IT-containing arms this lesion should be amenable for a one-time IT injection of VSV-IFNβ-NIS. At least one patient per IT cohort is required to have at least 2 measurable lesions per RECIST 1.1, one for a one-time IT injection of VSV-IFNβ-NIS and one to be used as a control. Priority enrollment in the IT-containing arms will be granted to patients with 2 measurable lesions per RECIST 1.1. At least one patient per dose level should have metastatic colorectal cancer. In order to fulfil these requirements, at least 3 or 4 patients will be required per escalation dose cohort. Other tumor types of particular interest based on prior experience with VSV or oncolytic viruses include malignant melanoma and endometrial cancer. When more than one cohort is open simultaneously, slot assignment will be determined by the sponsor in consultation with the PIs.
