The goal of this investigator-initiated, a single-arm, open-label, pilot study is to investigate the safety, tolerability, and efficacy of Intravenous CD-801 treatment in subjects with advanced hepatocellular carcinoma(HCC).
Condition of disease: advanced hepatocellular carcinoma.
Intervention： CD-801 will be administered intravenously for the treatment of HCC. The dosing regimen is planned for a second dose 14 ± 3 days post-initial treatment, followed by subsequent treatments every 28 ± 7 days, with adjustments made based on patient tolerance and therapeutic response. The trial is structured in two phases: dose escalation and dose expansion.
Dose Escalation Phase:
The study employs a i3+3 design to assess escalating CD-801 dosages: 25 μg, 50 μg, and 100 μg. Post-initial dose, a 14-day DLT observation will evaluate tolerability and safety, guiding dose adjustments or selection of the Recommended Dose (RD) for the expansion phase. Cohorts may include up to 9 participants, adjusted for safety.
Dose Expansion Phase:
The expansion phase will use the safe dosage and regimen from the escalation phase, with treatments starting 14 ± 3 days after the initial dose, then every 28 ± 7 days, adjusted as needed. It ends upon complete response, disease progression, toxicity, withdrawal, loss to follow-up, new oncological treatments, or investigator termination, with a final assessment 14 days post-last dose. The phase plans to enroll about 10 participants to further assess CD-801's safety, tolerability, and antitumor effects using mRECIST.
Drug: CD-801, a drug specifically designed to target liver cancer cells and facilitate the expression of HNF4α.
