DUBLIN, Ireland, Aug. 18, 2016 (GLOBE NEWSWIRE) -- Horizon Pharma plc (NASDAQ:HZNP), a biopharmaceutical company focused on improving patients’ lives by identifying, developing, acquiring and commercializing differentiated and accessible medicines that address unmet medical needs, today announced that the United States Patent and Trademark Office (USPTO) has granted a Notice of Allowance for U.S. patent application number 14/563,000 (U.S. publication number 2015-0141388), entitled "Delayed-Release Glucocorticoid Treatment of Rheumatoid Disease" that covers Horizon’s U.S. approved medicine RAYOS (prednisone) delayed-release tablets.
The 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 August 3, 2027. After issuance, Horizon plans to list the patent in the FDA's Approved Drug Products with Therapeutic Equivalence Evaluations, or Orange Book. This will be the eighth 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 more than 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 (a division of Vectura) for RAYOS/LODOTRA.
Important Safety Information
RAYOS is a corticosteroid indicated:
- As an anti-inflammatory or immunosuppressive agent for certain allergic, dermatologic, gastrointestinal, hematologic, ophthalmologic, nervous system, renal, respiratory, rheumatologic, specific infectious diseases or conditions and organ transplantation
- For the treatment of certain endocrine conditions
- For palliation of certain neoplastic conditions
- Known hypersensitivity to prednisone or any excipients in the formulation
WARNINGS AND PRECAUTIONS
- Corticosteroids can cause hypothalamic-pituitary-adrenal (HPA) axis suppression, Cushing's syndrome and hyperglycemia. Monitor patients for these conditions with chronic use. Taper doses gradually for withdrawal after chronic use.
- RAYOS may increase susceptibility to new infection and increase risk of exacerbation, dissemination or reactivation of latent infection. RAYOS may mask signs and symptoms of infection. The rate of infectious complications increases with increasing doses of corticosteroids.
- Corticosteroids can cause elevated blood pressure, salt and water retention and hypokalemia. Monitor blood pressure and sodium, potassium serum levels. RAYOS should be used with caution in patients with a history of recent myocardial infarction, congestive heart failure, hypertension or renal insufficiency.
- There is an increased risk of gastrointestinal (GI) perforation in patients with certain GI disorders. RAYOS may mask signs and symptoms of GI perforation.
- Corticosteroid use may be associated with behavioral and mood disturbances, including euphoria, insomnia, mood swings, personality changes, severe depression and psychosis. Existing conditions may be aggravated.
- Corticosteroid use may lead to inhibition of bone growth in children and adolescents and the development of osteoporosis at any age. Give special consideration to patients at increased risk of osteoporosis (e.g., postmenopausal women) before initiating corticosteroid therapy, and bone density should be monitored in patients on long-term corticosteroid therapy.
- Prolonged use of corticosteroids may result in cataracts, infections and glaucoma. Monitor intraocular pressure if corticosteroid therapy is continued for more
than 6 weeks.
- Do not administer live or attenuated vaccines to patients receiving immunosuppressive doses of corticosteroids.
- Long‐term use of corticosteroids can have negative effects on growth and development in children. Monitor pediatric patients on long‐term corticosteroid therapy.
- Fetal harm can occur with first trimester use of corticosteroids. Apprise women of potential harm to the fetus.
- Common adverse reactions for corticosteroids include fluid retention, alteration in glucose tolerance, elevation in blood pressure, behavioral and mood changes, increased appetite and weight gain.
