WAYNE, Pa., Nov. 17, 2016 /PRNewswire/ -- Egalet Corporation (Nasdaq: EGLT) ("Egalet"), a fully integrated specialty pharmaceutical company focused on developing, manufacturing and marketing innovative treatments for pain and other conditions, today announced the issuance of a United States patent covering OXAYDO® (oxycodone HCI, USP) tablets for oral use only–CII. Egalet licensed OXAYDO from Acura Pharmaceuticals and launched the product in the United States in September 2015.
The United States Patent and Trademark Office (USPTO) issued patent 9,492,443 broadly covering immediate-release pharmaceutical compositions comprising an opioid formulated with Acura Pharmaceutical's proprietary Aversion® Technology intended to discourage common routes of abuse, including snorting. The patent offers protection through 2024.
"This newly issued patent strengthens the overall protection for OXAYDO and will be listed in the Orange Book alongside five other patents covering OXAYDO," said Bob Radie, president and chief executive officer of Egalet. "Issuance of this patent further highlights the uniqueness of the OXAYDO formulation, the only approved immediate-release oxycodone designed to discourage abuse via one of the most common routes of oxycodone abuse—snorting."
OXAYDO is indicated for the management of acute and chronic moderate to severe pain where the use of an opioid analgesic is appropriate. OXAYDO is the first and only immediate release oxycodone product designed to discourage abuse via snorting because of an inactive ingredient that may cause nasal burning if OXAYDO is manipulated. In an intranasal human abuse potential double-blind, crossover study, six times more recreational users reported they would not take OXAYDO again compared to subjects exposed to immediate-release oxycodone (30 percent of subjects exposed to OXAYDO responded they would not take the drug again compared to five percent of subjects exposed to IR oxycodone). The clinical significance of the difference in drug liking and difference in response to taking the drug again reported in this study has not yet been established. There is no evidence that OXAYDO has reduced abuse liability compared to immediate-release oxycodone.
Egalet, a fully integrated specialty pharmaceutical company, is focused on developing, manufacturing and commercializing innovative treatments for pain and other conditions. Egalet has two approved products: OXAYDO® (oxycodone HCI, USP) tablets for oral use only –CII and SPRIX® (ketorolac tromethamine) Nasal Spray. In addition, using its proprietary Guardian™ Technology, Egalet is developing a pipeline of clinical-stage, product candidates that are specifically designed to deter abuse by physical and chemical manipulation. The lead programs, ARYMO™ ER, an abuse-deterrent, extended-release, oral morphine formulation, and Egalet-002, an abuse-deterrent, extended-release, oral oxycodone formulation, are being developed for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Egalet's Guardian Technology can be applied broadly across different classes of pharmaceutical products and can be used to develop combination products that include multiple active pharmaceutical ingredients with similar or different release profiles.

Important Safety Information for OXAYDO® (oxycodone HCI, USP) tablets for oral use only –CII
Indications and Usage
OXAYDO (oxycodone HCl, USP) is an immediate-release oral formulation of oxycodone HCl indicated for the management of acute and chronic moderate to severe pain where the use of an opioid analgesic is appropriate.
OXAYDO is contraindicated in patients with respiratory depression, paralytic ileus, acute or severe bronchial asthma or hypercarbia, or known hypersensitivity to oxycodone or any components of the product, or in any situation where opioids are contraindicated.
Warnings and PRECAUTIONS
Respiratory depression is a risk of OXAYDO, especially in elderly or debilitated patients, in those suffering from conditions accompanied by hypoxia, hypercapnia, or upper airway obstruction, or following large initial doses of opioids given to non-tolerant patients, or when given in conjunction with other agents that depress respiration. Use with extreme caution in patients with chronic obstructive pulmonary disease or cor pulmonale.
OXAYDO is a Schedule II controlled substance with an abuse liability similar to other opioids. OXAYDO may be abused by crushing, chewing, snorting or injecting the product and these practices pose a significant risk to the abuser that could result in overdose and death.
Patients receiving central nervous system depressants concomitantly with OXAYDO may exhibit an additive central nervous system depression, which may result in respiratory depression, hypotension, profound sedation, or coma. Patients should not consume alcoholic beverages, or any medications containing alcohol while taking OXAYDO.
In the presence of a head injury or other intracranial lesions, OXAYDO may cause markedly exaggerated elevation of intracranial pressure.
OXAYDO may cause severe hypotension in patients whose ability to maintain blood pressure has been compromised, may produce orthostatic hypotension in ambulatory patients and must be administered with caution in patients in circulatory shock.
Do not administer OXAYDO to patients with gastrointestinal obstruction. Use OXAYDO with caution in patients with biliary tract disease, including pancreatitis.
Use with caution and in reduced dosages in patients with severe renal or hepatic impairment, Addison's disease, hypothyroidism, prostatic hypertrophy, or urethral stricture, and in elderly or debilitated patients. Use with caution when administering to patients with CNS depression, toxic psychosis, acute alcoholism and delirium tremens; may aggravate convulsions in patients with convulsive disorders and may induce or aggravate seizures in some clinical settings.
Keep OXAYDO out of the reach of children.
OXAYDO may impair mental and/or physical abilities; use with caution with potentially hazardous activities.
Concomitant use of CYP3A4 inhibitors may increase opioid effects and of CYP3A4 inducers may decrease effects or possibly cause development of an abstinence syndrome in a patient who had developed physical dependence to oxycodone.
Serious adverse reactions that may be associated with OXAYDO include: respiratory depression, respiratory arrest, circulatory depression, cardiac arrest, hypotension, and/or shock.
The most common adverse reactions are nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia and somnolence.
Additional Drug Interactions
Muscle relaxants: enhances the neuromuscular blocking action of skeletal muscle relaxants and produces an increased degree of respiratory depression.
Mixed agonist/antagonist analgesics: may reduce the analgesic effects and/or may precipitate withdrawal symptoms.
Monoamine Oxidase Inhibitors (MAOIs): use not recommended with or within 14 days of stopping MAOIs.
Anticholinergics: increased risk for urinary retention and severe constipation.
