SANTA MONICA, Calif., March 09, 2017 (GLOBE NEWSWIRE) -- Opiant Pharmaceuticals, Inc. (“Opiant”) (OTCQB:OPNT), a specialty pharmaceutical company developing pharmacological treatments for addictions, today announced that its most recently issued U.S. patents, numbers 9,480,644 and 9,561,177 covering methods of use for NARCAN® Nasal Spray (“NARCAN”), are now listed in the U.S. Food and Drug Administration (FDA) publication, Approved Drug Products with Therapeutic Equivalence Evaluations , commonly known as the Orange Book.
“We are pleased with these new patent issuances and subsequent Orange Book listings. We now have four Orange Book-listed patents for NARCAN Nasal Spray,” said Roger Crystal, M.D., Chief Executive Officer of Opiant. “These latest patents reinforce our commitment to our commercialization partner, Adapt Pharma, as we further solidify the IP estate covering NARCAN. Additionally, these patents have broader implications for our proprietary development-stage pipeline as we continue to evaluate nasally-delivered naloxone and other pharmacological compounds for the treatment of a broad range of addictive behaviors with significant unmet medical needs.”
Patent 9,480,644 claims nasal spray formulations, devices, and methods of treatment covering the two-milligram dose of NARCAN, which was approved in January 2017. The patent provides for drug products adapted for nasal delivery via a pre-primed device filled with a pharmaceutical composition containing an opioid receptor antagonist. The patent also provides for methods of treating opioid overdose or its symptoms with the two-milligram formulation of NARCAN.
Patent, 9,561,177 claims nasal spray formulations and methods of treatment and covering the four-milligram dose of NARCAN® Nasal Spray. The patent provides for formulations with particular spray plume characteristics and geometry, and for methods of treating opioid overdose or narcotic-induced respiratory depression with the four-milligram formulation of NARCAN.
An Orange Book listing requires an Abbreviated New Drug Application (ANDA) applicant seeking FDA approval of a generic version of NARCAN Nasal Spray to notify the Company and its partner Adapt Pharma before it can obtain FDA approval. This would be subject to a 30-month stay of marketing approval and potentially longer if notification occurs and a patent infringement suit is successful.
