DEERFIELD, IL--(Marketwired - August 27, 2014) - Horizon Pharma, Inc. (NASDAQ: HZNP) today announced that the United States Patent and Trademark Office (USPTO) has issued Horizon a Notice of Allowance for U.S. patent application number 13/860,015 entitled "Delayed-Release Glucocorticoid Treatment of Rheumatoid Disease" that covers Horizon's U.S. approved product RAYOS® (prednisone) delayed release tablets.
"This patent allowance by the USPTO is not only another important milestone in protecting the commercial potential of RAYOS, but along with other recent allowances, demonstrates our strong overall commitment to protecting the innovation and commercial opportunity of our entire product portfolio," said Timothy P. Walbert, chairman, president and chief executive officer, Horizon Pharma.
This Notice of Allowance concludes the substantive examination of the patent application and will result in the issuance of a U.S. patent after administrative processes are completed. The U.S. patent scheduled to issue from this application will expire in 2027. After issuance, Horizon plans to list the U.S. patent in the FDA's Approved Drug Products with Therapeutic Equivalence Evaluations, or Orange Book. This will be the sixth U.S. patent to be listed in the Orange Book for RAYOS.
RAYOS, known as LODOTRA® in Europe, is a proprietary delayed-release formulation of low-dose prednisone. The pharmacokinetic profile of RAYOS is different with an approximately four-hour lag time from that of immediate-release prednisone formulations. In clinical trials studying use of RAYOS in rheumatoid arthritis (RA), patients were administered RAYOS at 10 p.m. with food. The delayed-release profile of RAYOS helps to achieve therapeutic prednisone blood levels at a time point when cytokine levels start rising during the middle of the night. While the pharmacokinetic profile of RAYOS differs in terms of lag time from immediate-release prednisone, its absorption, distribution and elimination processes are comparable.

RAYOS utilizes Skyepharma's proprietary Geoclock™ technology.
Outside the United States, LODOTRA is approved for the treatment of moderate to severe active RA when accompanied by morning stiffness in over thirty-five countries. Horizon has granted commercialization rights for LODOTRA in Europe, Asia (excluding Japan) and Latin America to its distribution partner Mundipharma International Corporation Limited. Horizon has an exclusive license from Skyepharma for RAYOS/LODOTRA.
