Efficacy and Safety of Intratumoral Injection of Recombinant Human Adenovirus Type 5 Combined With Tislelizumab and Lenvatinib in the Treatment of Advanced Hepatocellular Carcinoma

Recombinant Human Adenovirus Type 5( H101 )was administered intratumorally on day 1 and 5 of cycle 1 and cycle 2. If the sum of the maximum diameters of the lesions was less than or equal to 10 cm, the total dose was 1.0×10\^12 vp . If the sum of the maximum diameters of the lesions was more than 10 cm, the total dose was 1.5×10\^12 vp. Recombinant Human Adenovirus Type 5 was diluted to 30% of the total tumor volume with normal saline before administration. Under the guidance of ultrasound, percutaneous puncture was performed to the center of the tumor, and the solution was uniformly injected into the tumor. If there are multiple lesions, the distribution of each lesion should be proportional to the size of the tumor. No more than 5 lesions.

Lenvatinib was administered orally once daily started on day 1 of cycle 1 of the study until disease progression or unacceptable toxicity occurred or meet the end point of the study. For patients weighing less than 60 kg, the recommended daily dose was 8 mg once daily. For patients weighing ≥60 kg, the recommended daily dose was 12 mg once daily

Tislelizumab 200mg was administered intravenously every 3 week started on day 1 of cycle 3 until disease progression or unacceptable toxicity occurred or meet the end point of the study.
