ClinConnect Summary

This clinical trial is studying a new treatment for patients with hepatocellular carcinoma, a type of primary liver cancer. The researchers want to see how safe and effective a combination of two medications, MB07133 and Sintilimab, is for people with this condition. The trial is currently recruiting participants aged 18 to 70 who have been diagnosed with liver cancer that cannot be surgically removed and have at least one measurable tumor in the liver. To be eligible, patients should have stable liver function, expected survival of at least 12 weeks, and should not have used certain other cancer treatments recently.

Participants in the trial will receive the combination treatment and will be monitored closely for any side effects and how well the treatment works. It's important to know that there are specific health criteria that must be met to join the study, and individuals with certain medical conditions or those currently taking specific medications may not be eligible. If you or someone you know is interested in participating, it’s essential to discuss it with a healthcare provider to see if it’s the right choice.
