Opiant Pharmaceuticals, Inc. Announces FDA Orange Book Listing for New NARCAN® Nasal Spray Patent

SANTA MONICA, Calif., Aug. 04, 2017 -- Opiant Pharmaceuticals, Inc. (“Opiant”) (OTCQB:OPNT), a specialty pharmaceutical company developing pharmacological treatments for addictions and eating disorders, today announced that its most recently issued U.S. Patent, No. 9,707,226, covering methods of use for the two-milligram (2mg) formulation of 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.

“We are pleased with this new patent issuance and subsequent Orange Book listing. We now have six Orange Book-listed patents for NARCAN, and remain encouraged by our solid intellectual property position and enhanced product exclusivity,” said Roger Crystal, M.D., Chief Executive Officer of Opiant. “This latest patent also has the potential to be relevant to other products in development by Opiant.” 

U.S. Patent No. 9,707,226 claims nasal spray formulations and methods of treatment covering the 2mg dose of NARCAN, which was approved by the FDA 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 2mg formulation of NARCAN. An Orange Book listing requires an Abbreviated New Drug Application (ANDA) applicant seeking FDA approval of a generic version of NARCAN to notify the Company and its partner, Adapt Pharma Limited, before it can obtain FDA approval. This would be subject to a 30-month stay of marketing approval and potentially longer if such notification occurs and a patent infringement suit is successful.
