ClinConnect Summary

This clinical trial is investigating a treatment called WGI-0301 in combination with another medication named Sorafenib for adults with advanced liver cancer, specifically a type called hepatocellular carcinoma (HCC). The main goals of the study are to find the highest safe dose of WGI-0301 and to evaluate how well it works for patients who have already tried other immune therapies. The trial is currently not recruiting participants, but it will be open to adults aged 18 and older who have confirmed HCC and have not responded to first-line treatments.

To be eligible for this study, participants must have measurable cancer that is not suitable for surgery and have experienced disease progression after previous treatments. They should also be in relatively good health, with a life expectancy of at least 12 weeks and good liver function. Participants can expect regular check-ups and tests to monitor their condition and the effects of the treatment. It's important to note that this trial will not accept patients who are pregnant or breastfeeding, have certain other medical conditions, or have received specific previous treatments.

• • 3. Histologically or cytologically confirmed diagnosis of HCC. Diagnosis of HCC can be made without a biopsy if radiographic hallmarks of arterial hypervascularity and venous/ late phase washout are present by either dynamic contrast enhanced MRI or helical multidetector CT scan using contrast for a lesion \> 2 cm, or by both modalities for a lesion 1\~2 cm.
