Cryoablation Combined With Lenvatinib Plus QL1706 (Iparomlimab/Tuvonralimab) in Patients With Advanced Intrahepatic Cholangiocarcinoma

QL1706 will be administered by IV, 5 mg/kg on day 1 of each 21 day cycle until documented disease progression, development of unacceptable toxicity, participant request, or withdrawal of consent.

Lenvatinib will be administered (bodyweight ≥ 60 kg, 12 mg; \< 60 kg, 8 mg) orally daily until documented disease progression, development of unacceptable toxicity, participant request, or withdrawal of consent.

Cryoablation will be performed with a two-cycle freeze-thaw phase protocol; US or non-contrast CT images will be obtained to visualize the evolving ablation zone. Lenvatinib plus QL1706 will be administered 1-3 days after cryoablation.
