Conditions: Hepatocellular Carcinoma

Summary: to determine the maximum tolerated dose (mtd), and the recommended phase 2 dose of hia ipilimumab in combination with iv nivolumab by monitoring the dose limiting toxicity (dlt) within 1 month after ia ipilimumab administration in dose-escalation phase.

eligible. 17. resolved acute effects of any prior therapy to baseline severity or nci ctcae v5 grade ≤1 except for aes not constituting a safety risk by investigator judgment. 18. patients must be

be eligible. 2. patients with any active autoimmune disease or history of known or suspected autoimmune disease with the exception of patients with vitiligo, resolved/controlled asthma/atopy, controlled hypoadrenalism or hypopituitarism, and euthyroid patients with a history of grave-basedow"s disease (patients with controlled hyperthyroidism must be negative for thyroglobulin and thyroid peroxidase antibodies and thyroid stimulating immunoglobulin prior to inclusion). 3. a known or underlying medical condition that, in the opinion of the investigator, could make the administration of study drug hazardous to the subject or could adversely affect the ability of the subject to comply with or tolerate study. 4. requirement for daily supplemental oxygen 5. any of the following within

investigator if the patient fulfills the other inclusion/exclusion criteria. 8. evidence of active infection that requires systemic antibacterial, antiviral, or antifungal therapy ≤ 7 days prior to inclusion. 9. any other significant acute or chronic medical illness. any other sound medical, psychiatric, and/or social reason as determined by the investigator. 10. subjects who are unable to
