VG2025: a targeted therapy for advanced solid tumors

Official title: An Open-label, Multicenter Phase I/IIa Clinical Study Evaluating the Safety, Tolerability, Pharmacokinetic Profile, and Preliminary Efficacy of VG2025 Intravenous Treatment in Subjects With Advanced Solid Tumors

Run by Virogin Biotech Ltd. · NCT07682870 · Data updated 2026-11-12

This trial tests VG2025, an oncolytic HSV-1 therapy, in adults with advanced solid tumors that have stopped responding to standard treatments to see if it is safe and tolerable and to find a potential starting dose for future studies.

Is this trial a fit for you?

Likely a good fit

Adults aged 18-75 with advanced solid tumors refractory to standard therapy and positive for HSV-1 antibodies.

Probably not a fit

Patients whose tumors do not respond to VG2025 or who experience unacceptable toxicity may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an open-label, early-phase study enrolling adults with advanced solid tumors who have exhausted standard therapies. Participants must be HSV-1 seropositive and eligible for intravenous VG2025, which is a recombinant oncolytic HSV-1 engineered to express IL-12/15. The study will assess safety, tolerability, pharmacokinetics, and preliminary efficacy, with the goal of determining a recommended dose for Phase II. It is conducted in a single institution setting under the lead sponsorship of Virogin Biotech Ltd. and aims to establish a safe dosing framework for future trials.

Why it matters

Potential benefit: If successful, VG2025 could offer a new treatment option for patients with limited alternatives and help identify a dose for subsequent trials.

How similar studies have gone: Previous trials of oncolytic HSV-1 therapies have shown variable safety and signals of activity in solid tumors; this study tests a dual-regulated IL-12/15 design in a similar setting.
