SANTA MONICA, Calif., Oct. 27, 2016 (GLOBE NEWSWIRE) -- Opiant Pharmaceuticals, Inc. (“Opiant”) (OTCQB:OPNT), a specialty pharmaceutical company developing pharmacological treatments for substance use, addictive and eating disorders, announced today that its patent for NARCAN® Nasal Spray (“NARCAN”) is 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, patent number 9468747.
The patent for naloxone hydrochloride metered 4 milligram nasal spray, N208411, offers product exclusivity for NARCAN until 2035.
“The issuance of this patent and subsequent Orange Book listing significantly strengthens our intellectual property,” said Roger Crystal, M.D., Chief Executive Officer of Opiant. “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 us and our 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.”
Opiant successfully developed NARCAN, marketed by its partner and licensee, Adapt Pharma Limited (“Adapt”). In November 2015, NARCAN was approved by the FDA for emergency reversal of opioid overdose.
“There are now two Orange Book listed patents that cover NARCAN® Nasal Spray. This recent one also has broader applicability across Opiant’s portfolio,” said Dr. Crystal. “We expect to continue generating more intellectual property relevant for both NARCAN® Nasal Spray and our development pipeline.”
In December 2014, Opiant announced a licensing deal with respect to NARCAN with Adapt. Pursuant to the terms of the agreement, Opiant could receive total potential milestone payments of more than $55 million, plus up to double-digit percentage royalties on net sales.
