VSV-02 for advanced solid tumors

A Single-Arm, Open-Label, Compassionate Use Study of VSV-02 Administered Intravenously and Intratumorally in Patients With Advanced Solid Tumors

Phase 1 Interventional The First Affiliated Hospital of Xinxiang Medical College · NCT07260591

This treatment will try VSV-02 given into a vein and directly into tumors to see if it helps people with advanced solid tumors who have limited treatment options.

What this trial studies

VSV-02 is an engineered vesicular stomatitis virus designed to infect and lyse tumor cells and locally produce a CD3/PD-L1 bispecific antibody to recruit and activate T cells. This open-label, single-arm Phase 1 study gives VSV-02 intravenously and by intratumoral injection on day 1 of each 3-week cycle for up to six cycles using a dose-escalation design. Researchers will measure tumor responses (ORR, DCR, DoR), progression-free and overall survival per RECIST 1.1, and closely monitor safety and tolerability. Eligible patients must have advanced solid tumors with at least one measurable and injectable lesion and limited or no standard treatment options.

Who should consider this trial

Good fit: Adults (≥18) with histologically confirmed advanced solid tumors who progressed after at least two prior standard therapies or have no suitable standard options, with at least one measurable and intratumorally accessible lesion, ECOG 0–2, and adequate organ function.

Not a fit: Patients with symptomatic or untreated brain metastases, poor performance status, no lesions accessible for intratumoral injection, or who are pregnant/breastfeeding are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, VSV-02 could directly destroy injected tumors and stimulate a localized immune response that helps control metastatic disease and overcome PD‑1/PD‑L1 resistance.

How similar studies have performed: Oncolytic virus therapy (for example T‑VEC) has shown benefit in melanoma, but VSV-based vectors delivering a CD3/PD-L1 bispecific antibody are a novel approach with limited clinical data so far.
