A Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of VG2025 Intravenous Injection in Subjects With Advanced Solid Tumors

June 30, 2026 updated by: Virogin Biotech Ltd.

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

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Age 18 to 75 years (inclusive); Open to all genders.
  2. Phase I: Participants with advanced solid tumors who have failed standard therapy (due to intolerance or disease progression following treatment) as confirmed by histopathology and/or cytology, or for whom no standard therapy is currently approved.
  3. Participants must test positive for Herpes Simplex Virus Type 1 (HSV-1) antibodies (HSV-1 IgG or HSV-1 IgM).
  4. Within 7 days prior to the first administration of the study drug, female participants of childbearing potential must confirm a negative serum pregnancy test. Participants of childbearing potential and their partners must agree to use effective contraception during the study drug administration period and for 90 days after the last dose.

Exclusion Criteria:

  1. Participants experiencing an active herpes simplex virus (HSV) recurrence with corresponding clinical manifestations, such as cold sores, herpetic keratitis, herpetic dermatitis, or genital herpes; or those requiring anti-HSV treatment.
  2. Participants who have received anticancer therapy or radiation therapy within 4 weeks or 5 half-lives (whichever is shorter) prior to enrollment.
  3. Underwent major surgery (excluding needle biopsy or intravenous catheterization) or interventional/ablation therapy within 4 weeks prior to the first dose.
  4. Individuals with addiction to alcohol, drugs, or other substances; participants who have been abstinent for more than 2 years are eligible for en.
  5. Any other serious underlying medical conditions, or mental or psychological disorders, hereditary diseases, etc., that, in the investigator's judgment, may interfere with disease staging, treatment, or follow-up; affect the participant's compliance; or place the participant at high risk.
  6. Any other circumstances that, in the investigator's judgment, render the participant unsuitable for participation in the clinical trial.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
