About remetinostat
Remetinostat is a topical histone deacetylase (HDAC) inhibitor. Three clinical phase II studies, demonstrating remetinostat efficacy and safety, have been completed. The phase II study in mycosis-fungoides cutaneous T-cell lymphoma (MF-CTCL) showed reduced severity of CTCL skin lesions with an objective response rate (ORR) of 40% and a clinically significant reduction in the severity of pruritus (itching) in 80% of the patients. In addition, two investigator-initiated phase II studies have been conducted at Stanford University in the USA, demonstrating efficacy in cutaneous Squamous Cell Carcinoma (SCC), and showing 70% ORR and >50% complete histologic resolution in Basal Cell Carcinoma (BCC).
