Summary

The purpose of this study is to learn how well a combination of iparomlimab and tuvonralimab (QL1706), lenvatinib, radiotherapy, and hepatic arterial infusion chemotherapy (HAIC) works and how safe it is for people with hepatocellular carcinoma (HCC) that has grown into the portal vein, forming a portal vein tumor thrombus (PVTT).

Participants will receive iparomlimab and tuvonralimab together with lenvatinib, radiotherapy directed at the portal vein tumor thrombus, and HAIC, which delivers chemotherapy directly through the hepatic artery. Researchers will evaluate how long the cancer remains controlled without getting worse, how much the tumors shrink, how long participants survive, and whether the treatment makes surgery possible for some participants. Treatment-related side effects will also be assessed.

The study will also explore whether features in tumor tissue and blood are associated with treatment response and may help identify patients who are more likely to benefit from this treatment strategy.

Conditions

  • HCC - Hepatocellular Carcinoma

Interventions

DRUG

Iparomlimab and Tuvonralimab (QL1706)

Iparomlimab and tuvonralimab (QL1706) will be administered intravenously at 7.5 mg/kg on Day 1 of each 3-week cycle. Each infusion will be administered over 30-60 minutes. Treatment will continue for up to 2 years or until disease progression, unacceptable toxicity, or another protocol-defined reason for discontinuation.

DRUG

Lenvatinib

Lenvatinib will be administered orally once daily at 8 mg for participants weighing \<60 kg and 12 mg for participants weighing ≥60 kg. During HAIC treatment, lenvatinib will be withheld for 3 days before HAIC and for 7 days after HAIC. The interruption period may be extended at the investigator's discretion based on the participant's clinical condition and laboratory findings. Lenvatinib will continue for up to 2 years or until disease progression, unacceptable toxicity, or another protocol-defined reason for discontinuation.

RADIATION

Radiotherapy

External beam radiotherapy directed at the portal vein tumor thrombus (PVTT) will be initiated within 7 days after the first administration of QL1706. The radiation target will include the PVTT. Gross tumor volume will be delineated based on the venous or delayed phase of contrast-enhanced imaging, and a planning target volume margin of approximately 5-15 mm will be applied according to the protocol. SBRT will be delivered at a total dose of 18-40 Gy with 3-6 Gy per fraction.

PROCEDURE

hepatic arterial infusion chemotherapy (HAIC)

HAIC will be initiated during Cycle 2 of systemic therapy. Using a modified Seldinger technique, a catheter will be selectively placed in the main tumor-feeding hepatic artery for administration of FOLFOX chemotherapy. HAIC will be repeated every 3 weeks for up to 4 cycles, with the number of cycles adjusted according to the participant's clinical condition
