Cipher's revised NDA for CIP-TRAMADOL ER accepted for review by FDA



    Toronto Stock Exchange Symbol: DND

    MISSISSAUGA, ON, June 17 /CNW/ - Cipher Pharmaceuticals Inc. (TSX: DND)
today announced that its revised New Drug Application (NDA) for CIP-TRAMADOL
ER, its extended-release formulation of tramadol, has been accepted for review
by the U.S. Food and Drug Administration (FDA). Cipher expects the review to
be completed by October 2008.
    In May 2007, the Company received an approvable letter from the FDA
pertaining to its original 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. 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 Lipofen(R). 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
