CAMBRIDGE, Mass.--(BUSINESS WIRE)--Gloucester Pharmaceuticals announced today the presentation of positive data from an analysis of ISTODAX® (romidepsin) in a subset of patients from Gloucester’s registration study in cutaneous T-cell lymphoma (CTCL) at the 51st American Society of Hematology (ASH) Annual Meeting being held in New Orleans, LA. This analysis is an assessment of patients with CTCL who—in addition to skin disease and potential lymph node and visceral involvement—also had blood involvement. Blood involvement is characterized as having greater than five percent circulating Sézary (malignant) cells and is typically associated with advanced stage, aggressive disease. ISTODAX is a member of a new class of cancer drugs known as histone deacetylase (HDAC) inhibitors and was recently approved by the U.S. Food and Drug Administration for the treatment of cutaneous T-cell lymphoma in patients who have received at least one prior systemic therapy.
