VG-201

This is a Phase 1, open-label, dose-escalation trial using standard 3+3 dose-escalation design in patients with advanced malignant solid tumors. All patients within a given dose level cohort will be treated with the same dose schedule of VG2025, administered as intratumoral injections at Day 1 and Day 15 biweekly at each treatment cycle (monotherapy cohorts 1-4 and combination cohort 1) and on day 1 and either day 2 or day 3 at the first 2 cycles followed by day 1 only at subsequent cycles (combination cohort 2). Dose limiting toxicity (DLT) evaluation period is for 4 weeks, from the start of treatment, Day 1, through Day 28.
There are two parts to this study a monotherapy arm and a combination therapy arm. In the monotherapy arm the patients will receive VG2025 only. In the combination therapy arm the patients will receive VG2025 and Nivolumab

VG2025 is a Recombinant Human IL12/15 Dual-Regulated Oncolytic HSV-1 Injection. This Phase I study will be conducted in herpes simplex virus (HSV) -seropositive subjects with advanced malignant solid tumors that are refractory to conventional therapies. This is an open label study to determine the safety and tolerability of VG2025, and recommended dose of VG2025 for Phase II trials.
