Horizon Pharma Announces Receipt of Two Additional U.S. Patent Allowances for DUEXIS®

September 28, 2012

DEERFIELD, Ill., Sept. 28, 2012 /PRNewswire/ — Horizon Pharma, Inc. (NASDAQ: HZNP), announced today that it has received Notices of Allowance from the United States Patent and Trademark Office (USPTO) for U.S. Patent Application Serial No. 13/403,930 and U.S. Application Serial No. 13/403,923 both entitled “Stable Compositions of Famotidine and Ibuprofen” with claims that cover DUEXIS(®) (ibuprofen and famotidine) tablets. DUEXIS is indicated for the relief of signs and symptoms of rheumatoid arthritis and osteoarthritis and to decrease the risk of developing upper gastrointestinal ulcers.

The Notices of Allowance conclude the substantive examination of these patent applications and will result in the issuance of U.S. patents after administrative processes are completed. The patents scheduled to issue from these applications will expire in 2028 for the U.S. patents. After issuance, Horizon plans to list the U.S. patents in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations, or Orange Book.

“These recent Notices of Allowance in the U.S. represent an important expansion of the patent estate for DUEXIS,” said Timothy P. Walbert, chairman, president and chief executive officer, Horizon Pharma. “Horizon’s goal is to protect the commercial potential of DUEXIS to 2028 and these Notices of Allowance are a significant step toward achieving this goal.”

About DUEXIS
DUEXIS, a proprietary single-tablet combination of the NSAID ibuprofen and the histamine H2-receptor antagonist famotidine, is indicated for the relief of signs and symptoms of rheumatoid arthritis and osteoarthritis and to decrease the risk of developing upper gastrointestinal ulcers, which in the clinical trials was defined as a gastric and/or duodenal ulcer, in patients who are taking ibuprofen for those indications. The clinical trials primarily enrolled patients less than 65 years of age without a prior history of gastrointestinal ulcer. Controlled trials do not extend beyond 6 months.

Important Safety Information About DUEXIS
DUEXIS is not right for everyone. People who have had asthma, hives, or an allergic reaction to aspirin or other NSAIDs should not take DUEXIS. Women in the late stages of pregnancy should not take DUEXIS. People who have had allergic reactions to medications like famotidine (histamine H2?receptor antagonists) should not take DUEXIS.

Tell your health care provider right away if you have signs of active bleeding (persistent and unexplained) while you are taking DUEXIS.

NSAID?containing medications like DUEXIS can cause high blood pressure or make existing high blood pressure worse, either of which can increase the chance of a heart attack or stroke. Your health care provider should check your blood pressure while you are taking DUEXIS.

Before you start taking DUEXIS, tell your health care provider if you have heart problems, kidney problems, or liver problems, or if you are taking medications for high blood pressure. DUEXIS can increase the chance of potentially significant liver injury and/or kidney injury, which may be fatal. Stop taking DUEXIS immediately and contact your health care provider if you experience any signs and/or symptoms of liver or kidney injury.

Serious allergic reactions, including skin reactions, can happen without warning and can be life threatening. Stop taking DUEXIS and consult your doctor immediately if you get a skin rash or if you start to have problems breathing or swallowing or if you develop swelling of your face or throat.

The most common side effects of DUEXIS include nausea, diarrhea, constipation, upper abdominal pain and headache.
