About Cipher Pharmaceuticals Inc.

Cipher Pharmaceuticals is a commercial-stage 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 is being marketed in the United States by Kowa Pharmaceuticals America under the label Lipofen®. Cipher's second product, an extended-release version of the pain reliever tramadol, received FDA approval in May 2010 and the Company's third product, a novel formulation of the acne treatment isotretinoin, is in its final Phase III safety study.

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.
