NCT05223816 · View on ClinicalTrials.gov ↗
Study Summary
Safety Run-in Cohort (cohort 1): 10 patients will be treated with IT injection of VG161 in the cohort 1 at dose level of 1.0x10E8 PFU x 3 days. Monotherapy Cohorts (Cohort 2 and 3) Cohort 2 (HCC) This part is a single-agent, single one-dose level and single-arm design. Approximately 39 subjects will be enrolled in the study to receive VG161. In the first stage, 21 subjects will be enrolled. If there is only 1 or fewer subjects has been observed with objective response and no more than 12 (\<13) subjects have PFS longer than 3 months, the trial will be stopped. Otherwise, this study will continue to enter the second stage, and 18 additional subjects will be added, and the total number of trial subjects will reach 39. Cohort 3 (ICC) This part is a single-agent, single one-dose level and single-arm design. The trial will be carried out in two periods. In the first period, a total of 20 subjects will be enrolled. If there is only 1 or fewer response case in the 20 subjects, the trial will be stopped to investigate the efficacy of the IP, otherwise, subjects will continue to enter the second period, and 13 additional subjects will be added, and the total number of trial cases will reach 33. Cohort 4 (ICC and HCC) Combination with Nivolumab Combination cohort and subjects will receive VG161 at the same schedule as the monotherapy cohorts and 240 mg of intravenous Nivolumab on days 8 and 15 of each treatment cycle. The Nivolumab dose can be changed to 480 mg every 4 weeks after cycle one based on investigator's discretion.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05223816
The ClinicalTrials.gov registry entry for NCT05223816 describes a study currently listed as recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 97 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Virogin Biotech Canada, which has 2 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Hepatocellular Carcinoma appearing as the primary indexed condition, and to 2 interventions — of which Nivolumab Injection [Opdivo] is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05223816 reports 3 study locations spanning 3 distinct geographic areas — top geographies include Arizona, Florida, Minnesota. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
