Adamis Pharmaceuticals Announces Patent Litigation Regarding Its Higher Dose Naloxone Injection Product

SAN DIEGO, May 21, 2019 — Adamis Pharmaceuticals Corporation (NASDAQ: ADMP) today announced that on May 20, 2019, it received notice that it had been named and served as a defendant in a lawsuit filed by kaléo Inc. in the United States District Court for the District of Delaware regarding Adamis’ higher dose naloxone injection product candidate for the treatment of opioid overdose, for which Adamis has previously submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) that is being reviewed by the agency. The complaint alleges, among other things, that the company’s product candidate infringes patents purportedly held by kaléo relating to its naloxone auto-injector product. The action was filed under the provisions of the Hatch-Waxman Act in response to Adamis’ Paragraph IV certification regarding the kaléo patents as part of the company’s NDA process, and results in an automatic stay of any final approval by the FDA of Adamis’ NDA. Adamis does not anticipate this stay would interrupt or delay the FDA’s ongoing review of the NDA; however, if the patent dispute is unresolved by the time the FDA was prepared to grant an approval, the company believes that the agency would grant conditional approval until the sooner of October 4, 2021 or until final resolution of the matter before the court, whichever occurs sooner.

Adamis believes that its naloxone injection product, which combines a generic formulation of naloxone with Adamis’ proprietary injection device, does not infringe any valid and enforceable patent held by kaléo and that kaléo’s complaint is without merit. Adamis intends to defend against kaléo claims and pursue all available legal remedies available to the company against kaléo and, if appropriate, its outside counsel.


In December 2018, Adamis filed an NDA relating to its higher dose naloxone injection product. In March 2019, Adamis received a notice from the FDA that the NDA was sufficiently complete to permit a substantive review with a target action date of October 31, 2019. As is part of this kind of application, Adamis’ NDA included Paragraph IV certification with respect to certain patents listed in the FDA’s Orange Book for kaléo, Inc.’s EVZIO® product. As contemplated under the applicable federal laws and procedures, Adamis certified that each was invalid, unenforceable, or will not be infringed by the Adamis naloxone injection product and sent a notice letter to kaléo informing kaléo of the Paragraph IV certification.

About Naloxone Injection

Naloxone is an opioid antagonist used to treat narcotic overdoses. Naloxone, which is generally considered the drug of choice for immediate administration for opioid overdose, blocks or reverses the effects of the opioid, including extreme drowsiness, slowed breathing, or loss of consciousness. Common opioids include morphine, heroin, tramadol, oxycodone, hydrocodone and fentanyl. According to statistics published by the Centers for Disease Control and Prevention, in 2017, drug overdoses resulted in approximately 72,000 deaths in the United States – nearly 200 deaths per day. Drug overdoses are now the leading cause of death for Americans under 50, and the proliferation of more powerful synthetic opioids, such as fentanyl and its analogues, could result in future increases in the number of deaths resulting from opioid overdoses. Based on the current opioid epidemic, particularly involving the more potent fentanyl narcotics, the company and others have published reports supporting the need for a higher dose naloxone product.

In December 2018, the joint meeting of the Anesthetic and Analgesic Products Advisory Committee and the Drug Safety and Risk Management Advisory Committee voted in favor of adding labeling language that recommends co-prescription of naloxone for all or some patients prescribed opioids. Medicare (HHS) has also recommended co-prescribing naloxone with opioids under certain conditions. These recommendations could significantly increase the naloxone market.
