A Clinical Study to Evaluate the Efficacy and Safety of VG2025 in Intrahepatic Cholangiocarcinoma

April 7, 2026 updated by: Virogin Biotech Ltd.

An Open-label Phase IIa Clinical Trial to Evaluate the Efficacy and Safety of VG2025 in the Treatment of Advanced Intrahepatic Cholangiocarcinoma

VG2025 is a Recombinant Human IL12/15 Dual-Regulated Oncolytic HSV-1 Injection. Currently, one phase I dose escalation safety study has been completed in China and the United States respectively, both demonstrating excellent safety profiles with no dose-limiting toxicities (DLTs) observed and no maximum tolerated dose (MTD) identified. Moreover, it has shown preliminary efficacy in treating advanced tumors. Considering the actual clinical needs and the volume of intratumoral administration, a more appropriate recommended phase 2 dose (RP2D) level has been selected for the phase II clinical trial.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

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
