Ceptaris Announces Publication in JAMA Dermatology of Positive Clinical Results for Mechlorethamine Gel in Early Stage Mycosis Fungoides, the Most Common Type of Cutaneous T-Cell Lymphoma

MALVERN, Pa.--(BUSINESS WIRE)--Ceptaris Therapeutics, Inc., a privately held specialty pharmaceutical company, announced today that the results of a pivotal trial comparing its proprietary gel formulation of mechlorethamine hydrochloride 0.02% to pharmacy-compounded mechlorethamine ointment for the treatment of early stage mycosis fungoides (MF), the most common form of cutaneous T-cell lymphoma (CTCL), have been published in JAMA Dermatology (formerly Archives of Dermatology).¹

Topical mechlorethamine preparations are currently recommended as first line-treatment for early stage CTCL by the National Comprehensive Cancer Network (NCCN). However, there are no FDA approved topical mechlorethamine products, limiting availability to non-standardized, pharmacy-compounded preparations.

The pivotal trial was a randomized, observer-blinded clinical study designed to determine if mechlorethamine gel was non-inferior to a pharmacy-compounded ointment in patients with MF. The study enrolled 260 patients at 13 U.S. centers and is the largest randomized trial ever conducted in patients with stages IA, IB and IIA MF.

The study met or exceeded the pre-specified criteria for non-inferiority. Most adverse events related to mechlorethamine gel were characterized as local skin irritation. Approximately 20 percent of mechlorethamine gel-treated patients withdrew from the study because of these events.

The Company is planning a US resubmission in early 2013 and a MAA submission in the EU for mid-2013.
