METHYLPARABEN SUBEROHYDROXAMIC ACID PHENYL ESTER (more known as Remetinostat), a histone deacetylase (HDAC) inhibitor, was developed for the treatment of cutaneous T cell lymphoma (CTCL). This drug is participating in phase II clinical trial to evaluate the efficacy, safety, and tolerability to skin lesions in patients with early-stage cutaneous T-cell lymphoma. In May 2019 was announced the positive results from phase II trial of remetinostat in basal cell carcinoma (BCC) patients. Initial results suggest that remetinostat gel offers a potentially effective and well-tolerated, non-surgical intervention for the treatment of localized BCCs. The unique design of remetinostat enables topical application, making it active only in the skin. As soon as it reaches the blood stream, it is degraded, avoiding the side effects associated with other HDAC inhibitors. Besides, remetinostat was studied as the treatment of plaque psoriasis; however, this study was discontinued.
