42TiP A multicenter, randomized, double-blind phase III study of HBI-8000 combined with nivolumab versus placebo with nivolumab in patients with unresectable or metastatic melanoma not previously treated with PD-1 or PD-L1 inhibitors

Abstract

HBI-8000 also known as tucidinostat is an orally bioavailable, low-nanomolar inhibitor of cancer-associated histone deacetylase enzymes. HBI-8000 is a histone deacetylase inhibitor (HDACi), and as an epigenetic regulator modulating the gene expression, without changing the DNA sequence. HBI-8000 is being developed as a monotherapy for the treatment of hematological malignancies and in combinations for the treatment of solid tumors such as melanoma, breast, kidney, and lung cancers.
