Tace With Icaritin in First-line Treatment of Middle and Advanced HCC in Child Grade B Patients

Prospective Single-arm, Single-center Exploratory Clinical Study on Efficacy and Safety of Interventional Therapy Combined With Icaritin in First-line Treatment of Middle and Advanced HCC in Child Grade B Patients

Icaritin is a drug that has been approved by the National Medical Products Administration (NMPA) based on a multicenter, randomized, double-blind, parallel-controlled Phase III clinical trial - SNG1705 ICR-1. It is used for patients with unresectable hepatocellular carcinoma who are not suitable for or refuse standard treatment and have not previously received systemic therapy. According to numerous studies, in tumor cells, Icaritin can downregulate the expression of TNF-α, IL-6, PD-L1 and exert anti-tumor effects. At the same time, it regulates the tumor immune microenvironment by reducing the secretion of TNFa and IL-6 as well as inhibiting PD-L1 expression through decreasing MDSC cell proportion. Importantly, Icaritin has excellent safety profile and greatly ensure patients' quality of life clinically. Rare grade 3-4 TRAEs were observed in clinical trials which is uncommon among existing standard drugs. Good safety is a prerequisite for combination therapy; therefore, further exploration of optimal drug combinations is worth considering. Thus, TACE+Icaritin may potentially optimize treatment strategies for patients with poor liver function reserve.

Child B patients have a lower tolerance to targeted immunotherapy, and combining interventional therapy with targeted immunotherapy can result in an accumulation of toxic side effects leading to disease progression. Additionally, repeated local interventions can further deteriorate liver function. These patients currently face limited treatment choices. Apatinib has minimal adverse reactions and has been recommended by experts as a level I option for Child B patients in the HCC 2022 CSCO guidelines. Therefore, combining interventional therapy with apatinib holds promise in improving survival outcomes for Child B patients.
