FDA Says More Studies Needed for Cipher Pharmaceuticals's Acne Drug

MISSISSAUGA, ON, Aug. 13 - Cipher Pharmaceuticals today announced that the U.S. Food and Drug Administration (FDA) has responded to the Company's request for formal dispute resolution of the decision to issue an approvable action for Cipher's CIP-ISOTRETINOIN New Drug Application (NDA). In the letter to Cipher, the representative from the FDA agreed with the Division of Dermatology and Dental Products's view that an additional clinical study is needed to further demonstrate the safety of CIP-ISOTRETINOIN.

 

"While we continue to believe that the clinical question raised was adequately addressed in the NDA, we are reviewing their response to determine the most appropriate path forward to achieve approval," said Larry Andrews, President and CEO of Cipher.

About Cipher Pharmaceuticals Inc.

Cipher Pharmaceuticals is a drug development company focused on commercializing novel formulations of successful, currently marketed molecules using advanced drug delivery technologies. Cipher's strategy is to in-license products that incorporate proven drug delivery technologies and advance them through the clinical development and regulatory approval stages, after which the products are out-licensed to international partners. Because Cipher's products are based on proven technology platforms applied to currently marketed drugs, they are expected to have lower approval risk, shorter development timelines and significantly lower development costs. The Company's lead compound, CIP-FENOFIBRATE, received final approval from the U.S. Food and Drug Administration and Health Canada in the first quarter of 2006. Beginning in the fourth quarter of 2007, the product will be marketed in the United States by ProEthic Pharmaceuticals under the label Lipofen(TM). In addition, Cipher is developing formulations of the pain reliever tramadol and the acne treatment isotretinoin.

Cipher is listed on the Toronto Stock Exchange under the symbol 'DND' and has approximately 24 million shares outstanding. For more information, please visit www.cipherpharma.com.
