Cipher provides CIP-ISOTRETINOIN regulatory update

    Toronto Stock Exchange Symbol: DND

    MISSISSAUGA, ON, Aug. 13 /CNW/ - Cipher Pharmaceuticals Inc. (TSX: DND)
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
