About this study

Official title: A Clinical Study of Iparomlimab and Tuvonralimab Combined With Lenvatinib, Radiotherapy, and Hepatic Arterial Infusion Chemotherapy as First-Line Treatment for Hepatocellular Carcinoma With Portal Vein Tumor Thrombus

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.

Read the detailed description

This is a prospective, single-center, single-arm Phase II study designed to evaluate the efficacy and safety of a multimodal first-line treatment strategy consisting of iparomlimab and tuvonralimab (QL1706), lenvatinib, radiotherapy, and hepatic arterial infusion chemotherapy (HAIC) in patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT). A total of 35 participants are planned to be enrolled.

Treatment will be administered according to the following sequence. Iparomlimab and tuvonralimab (QL1706) will be administered intravenously at a dose of 7.5 mg/kg on Day 1 of each 3-week cycle, with each infusion given over 30-60 minutes. Lenvatinib will be administered orally once daily at 8 mg for participants weighing <60 kg and 12 mg for those weighing ≥60 kg.

PVTT-directed external beam radiotherapy 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. A planning target volume margin of approximately 5-15 mm will be added according to the protocol. Stereotactic body radiotherapy will be delivered at a total dose of 18-40 Gy, with a dose of 3-6 Gy per fraction.

HAIC will be initiated in combination with the second cycle of QL1706. 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 according to the participant's clinical condition and laboratory findings. HAIC will be performed using a FOLFOX-based regimen through a catheter selectively placed in the main tumor-feeding hepatic artery. Oxaliplatin will be administered at 85 mg/m² by hepatic arterial infusion over 3 hours, followed by leucovorin calcium at 200 mg/m² over 3-5 hours. Fluorouracil will then be administered at 400 mg/m² by hepatic arterial injection, followed by 2400 mg/m² as a continuous hepatic arterial infusion over 46 hours. 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.

QL1706 and lenvatinib will be continued for up to 2 years or until disease progression, unacceptable toxicity, or another protocol-defined reason for treatment discontinuation. Tumor response will be assessed every 2 treatment cycles, corresponding to approximately every 6 weeks, according to modified Response Evaluation Criteria in Solid Tumors (mRECIST). Participants who achieve sufficient tumor regression will be reviewed by a multidisciplinary team, and those considered suitable for curative resection may undergo conversion surgery.

The primary objective of the study is to evaluate progression-free survival. Secondary assessments include objective response rate, disease control rate, duration of response, overall survival, conversion-to-surgery rate, pathological complete response in participants undergoing surgery, and treatment safety.
