Cipher provides regulatory update for CIP-TRAMADOL ER

MISSISSAUGA, ON, May 13 (HSMN NewsFeed) - Cipher Pharmaceuticals Inc. (TSX: DND ) today announced that a revised New Drug Application (NDA) has been submitted to the U.S. Food and Drug Administration (FDA) for CIP-TRAMADOL ER, its extended-release formulation of tramadol. In May 2007, the Company received an approvable letter from the FDA pertaining to its NDA for CIP-TRAMADOL ER.

Cipher's revised NDA includes data from additional pharmacokinetic studies conducted by the Company comparing CIP-TRAMADOL ER to UltramŽ ER.

After considering feedback from the FDA appeal process and the results of the additional statistical sensitivity analysis of existing data suggested by the FDA, Cipher and its advisors concluded that submitting the revised NDA provided the most expeditious path to final regulatory approval.

Subject to FDA acceptance for filing, Cipher expects the review to be completed by October 2008. It is possible that the submission could trigger patent infringement litigation and a stay of up to 30 months under the Hatch-Waxman Act.

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. The product is being marketed in the United States by ProEthic Pharmaceuticals under the label LipofenŽ. In addition, Cipher is developing formulations of the pain reliever tramadol (FDA approvable letter in May 2007) and the acne treatment isotretinoin (FDA approvable letter in April 2007).

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.
