Toronto Stock Exchange Symbol: DND

MISSISSAUGA, ON, May 13 /PRNewswire-FirstCall/ - 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 Ultram(R) 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.
