             and PT prolongation time no more than 6s of ULN
          -  Appropriate renal function: Creatinine ≤ 1.5 × ULN, or creatinine clearance (CCr) >50
             mL/min (using the Cockcroft-Gault formula):
        Female: CrCl = ((140 - age) × body weight (kg) × 0.85) / 72 × serum creatinine (mg/dL)
        Male: CrCl = ((140 - age) × body weight (kg) × 1.00) / 72 × serum creatinine (mg/dL)
        • Women of childbearing potential: must agree to abstain from sexual activity or use a
        contraceptive method with a failure rate of less than 1% for at least 6 months during the
        treatment period and after the last dose.
        If a female patient has menstruated and has not yet reached postmenopausal status (no
        menstrual periods for ≥12 months continuously, and no other causes for menopause except
        surgical sterilization), and has not undergone sterilization surgery (removal of the
        ovaries and/or uterus), she is considered to be of childbearing potential.

          -  Pregnant (positive pregnancy test before medication) or lactating women. Known allergy
             or intolerance to recombinant humanized PD-1 monoclonal antibody drugs or lenvatinib
             and its components (or any excipient).
          -  Received local anti-tumor treatment within 4 weeks before the first study drug
             treatment, including but not limited to surgery, radiotherapy, hepatic artery
             embolization, TACE, hepatic artery infusion, radiofrequency ablation, cryoablation, or
             percutaneous ethanol injection (palliative radiotherapy for bone metastases at least 2
             weeks before study drug treatment is allowed);
          -  Past or current grade 3 or above digestive fistula or non-digestive fistula (such as
             skin) according to the CTCAE 5.0 standard.

             significantly affect drug intake and absorption.
