Efficacy and Safety Comparison Between PD-1 Inhibitor Combined With Lenvatinib or With Regorafenib For UHCC After Failure of First-line Treatment

There is no definitive evidence regarding the therapeutic efficacy of PD-1 inhibitors combined with tyrosine kinase inhibitors (TKIs) after disease progression following first-line treatment with bevacizumab plus sintilimab for unresectable hepatocellular carcinoma (HCC). There is insufficient evidence to support which TKI should be combined with PD-1 inhibitors as the optimal second-line treatment option after first-line therapy failure. Data on the application of lenvatinib as a second-line treatment are limited, whereas the efficacy and safety of regorafenib combined with PD-1 inhibitors have been preliminarily validated \[9\]. Therefore, this study aims to compare the efficacy and safety of PD-1 inhibitors combined with either lenvatinib or regorafenib after disease progression following first-line bevacizumab plus sintilimab treatment for unresectable HCC, providing evidence-based guidance for the selection of second-line treatment regimens in clinical practice.

Efficacy and Safety Comparison Between Intensified Therapy and Conversion Therapy For Advanced HCC After Failure of First-line

Although immunotherapy-based therapies (including targeted-immunotherapy or dual-immunotherapy protocols) have become the first-line standard treatment for advanced hepatocellular carcinoma (HCC), there remains a lack of high-level evidence to guide the selection of second-line therapies following progression in immune checkpoint inhibitors (ICIs). Additionally, direct comparative data are scarce for combination treatment modalities such as "continuation of the original first-line regimen with added agents" or "switching to agents with different mechanisms". To address this clinical need and explore novel second-line treatment strategies for advanced HCC, we plan to conduct an exploratory clinical trial to investigate the efficacy and safety comparison between intensified therapy (plus lenvatinib) and conversion therapy (regorafenib combined with PD-1 inhibitor) for advanced hepatocellular carcinoma after failure of fFirst-line bevacizumab plus sintilimab.

Dalpiciclib Plus Camrelizumab for HCC Patients Who Have Previously Received ICI Treatment

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.
