Clinical Trial Summary

This is a randomized, controlled, phase 2 study to assess the efficacy and safety of ablation followed by tislelizumab versus ablation alone in patients with early recurrent hepatocellular carcinoma.

Description:

Ablation is one of the main treatments for early recurrent HCC, and its immune stimulation is expected to improve the efficacy of anti-PD-1 immune checkpoint inhibitor therapy. Tislelizumab is a new immunotherapy agent with independent intellectual property rights in China, which is highly efficient and safe. It is of great value to combine Tislelizumab with ablation to reduce the risk of recurrence in HCC patients. In this study, early-stage HCC patients with high risk of recurrence would be included and randomly assigned to receive ablation plus Tislelizumab or ablation alone. The tumor recurrence, overall survival and safety would be observed and recorded to analyze whether Tislelizumab can reduce the recurrence rate.

2. Prior organ allograft or allogeneic bone marrow transplantation

3. All toxicities attributed to prior anti-cancer therapy other than neuropathy, alopecia and fatigue must have resolved to Grade 1 (NCI CTCAE version 5.0) or baseline before administration of study drug. Subjects with toxicities attributed to prior anti-cancer therapy which are not expected to resolve and result in long lasting sequelae are permitted to enroll. Neuropathy must have resolved to Grade 2 (NCI CTCAE version 5.0).

4. Active bacterial or fungal infections requiring systemic treatment within 7 days

5. Use of other investigational drugs (drugs not marketed for any indication) within 28 days or at least 5 half-lives (whichever is longer) before study drug administration

6. Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease.

Related Conditions & MeSH terms

• Carcinoma
• Carcinoma, Hepatocellular
• Recurrence
• Recurrent Hepatocellular Carcinoma

Intervention

Drug:
• Tislelizumab
200mg, iv. drip, Q3W. Tislelizumab will start within 3-7 days after ablation treatment. The longest course of treatment is 12 months.

Procedure:
• Ablation
After local anesthesia and intravenous sedative injection, the unipolar needle would be gradually inserted into the lesion and placed on the deepest edge of the lesion. The ablation electrode is a unipolar needle with a bare end of 2 or 3 cm (adjusted to tumor size). The ablation power is 150 watts (range from 100 to 200 watts). In general, the average ablation time for each lesion is about 12 minutes (ranging from 10 to 15 minutes).
