• Agreement combines Opiant’s opioid antagonist OPNT003 nasal nalmefene, with Aptar's FDA-approved Unit Dose System delivery device

• Reinforces Opiant’s continued commitment to innovative overdose treatment options as America’s opioid epidemic worsens
  
  
• OPNT003 nasal nalmefene remains on track for NDA submission by the end of 2021
  

SANTA MONICA, Calif., Oct. 29, 2020 (GLOBE NEWSWIRE) -- Opiant Pharmaceuticals, Inc. (“Opiant”) (NASDAQ: OPNT) today announced it has entered into an agreement with drug delivery specialist Aptar Pharma (“Aptar”), for the development of OPNT003 nasal nalmefene for use in conjunction with Aptar’s Unit Dose System (UDS) for the treatment of opioid overdose.

The Aptar UDS has been approved by the U.S. Food and Drug Administration (FDA) with multiple drug products marketed in the United States, including our internally developed and licensed NARCAN^® Nasal Spray. 

“We believe our decision to partner with Aptar’s proven nasal delivery system represents a timely and strategic step forward for Opiant as we continue to advance OPNT003 as a potentially life-saving treatment for opioid overdose in the face of America’s worsening opioid epidemic,” said Roger Crystal, MD, President and Chief Executive Officer of Opiant.

Opioids were involved in 51,574 overdose deaths in 2019 (71% of all drug overdose deaths) according to provisional data by the Centers for Disease Control and Prevention (CDC). Three out of four opioid-involved overdose deaths involve synthetic opioids, such as fentanyl, which is 50 times more potent than heroin. The COVID-19 coronavirus has worsened the outlook for 2020. The American Medical Association (AMA) recenty cited that more than 40 states have reported rising opioid overdose-related fatalities amid the pandemic.

OPNT003, nasal nalmefene, is being investigated to treat opioid overdose, which, if proven and ultimately approved, may be particularly useful in treating overdoses stemming from use of synthetic opioids, such as fentanyl. The development of OPNT003 is supported by a grant from the National Institutes of Health (NIH) and a contract from the Biological Advance Research and Development Agency (BARDA), who are interested in its potential as an antidote for use in a civilian mass casualty event. Opiant continues to anticipate filing a New Drug Application (NDA) in the United States for OPNT003 under a 505(b)(2) filing strategy by the end of 2021.

In parallel, Opiant terminated an agreement with Aesica Queenborough Limited (which was ultimately acquired by Recipharm upon its acquisition of Consort Medical plc, and its Bespak Division, in 2019) to use its Unidose^® Xtra device for OPNT003.
