The recently approved Zolinza (vorinostat), the first anticancer drug to be developed by Merck & Co. in 20 years, targets a little-known malignancy that's often mistaken for eczema or psoriasis. Vorinostat, also known as suberoylanilide hydroxamic acid (SAHA), is indicated for the treatment of cutaneous manifestations in patients with cutaneous T-cell lymphoma (CTCL), a rare form of non-Hodgkin's lymphoma, who have progressive, persistent, or recurrent disease on or following two systemic therapies.
