This is an open-label, multicenter, phase Ib/II study, which includes a Part I (phase Ib) and a Cohort Expansion part (Part II; phase II). Part I of the study is designed to assess the safety, tolerability, PK profiles, efficacy, and PD biomarkers of the study medications in patients with HCC. Part II of the study is designed to assess the efficacy, safety, and PD biomarkers.
This open-label, phase Ib/II, multicenter study evaluated the safety, tolerability, efficacy, and PK of chidamide in combination with regorafenib in patients with HCC. Chidamide, a histone deacetylase inhibitor, functions as a tumor inhibitor. Regorafenib, a receptor tyrosine kinase inhibitor, was approved as second-line systemic treatment for HCC patients.
