A Prospective, Randomized, Two-Cohort, Exploratory Clinical Study of Dalpiciclib Combined With Camrelizumab in Patients With Unresectable Hepatocellular Carcinoma Previously Treated With Immune Checkpoint Inhibitors
While immune-based therapies (including targeted-immune or dual-immune regimens) have become first-line standard for advanced hepatocellular carcinoma (HCC), there is a lack of high-level evidence to guide second-line treatment after progression on immune checkpoint inhibitors (ICIs). Preclinical studies suggest synergistic antitumor activity between CDK4/6 inhibitors and PD-1/PD-L1 blockade. However, no clinical studies have yet evaluated the combination of dalpiciclib and camrelizumab in this setting. To address this unmet need and explore novel second-line strategies for advanced HCC, we plan to conduct an exploratory clinical trial investigating the efficacy and safety of dalpiciclib plus camrelizumab in patients with unresectable HCC previously treated with ICIs.
• The diagnosis of HCC was based on the diagnostic criteria for HCC used by the European Association for the Study of the Liver (EASL)
• Patients must have at least one tumor lesion that can be accurately measured according to EASL criteria.
• Barcelona clinic liver cancer-stage C
• Patients who have previously received first-line treatment with ICI treatments (including PD-1/PD-L1/CTLA-4) and who have shown tumor progression as confirmed by imaging studies.
• Eastern Cooperative Oncology Group performance status of 0 to 1
• No Cirrhosis or cirrhotic status of Child-Pugh class A only
• Not amendable to surgical resection ,local ablative therapy and any other cured treatment.
• The following laboratory parameters:
⁃ Hemoglobin ≥ 8.5 g/dL Total bilirubin ≤ 30mmol/L Serum albumin ≥ 30 g/L ASL and AST ≤ 5 x upper limit of normal Serum creatinine ≤ 1.5 x upper limit of normal INR ≤ 1.5 or PT/APTT within normal limits Absolute neutrophil count (ANC) \>1,500/mm3
⁃ • Ability to understand the protocol and to agree to and sign a written informed consent document
