Alongside over-the-counter NARCAN® Nasal Spray 4 mg, prescription KLOXXADO® (naloxone HCl) Nasal Spray 8 mg will expand Emergent’s ability to distribute multiple life-saving opioid overdose emergency treatments to patients, customers and communities in needFocus remains on increasing access, raising awareness and ensuring strong supply to meet the ongoing demand of naloxone nasal spray GAITHERSBURG, Md., Jan. 14, 2025 (GLOBE NEWSWIRE) -- Emergent BioSolutions Inc. (NYSE: EBS) announced today that it has entered into an agreement to obtain exclusive commercial rights in the U.S. and Canada to Hikma Pharmaceuticals’ KLOXXADO® (naloxone HCl) Nasal Spray, an 8 mg naloxone agent that is approved for the emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system depression.1 This six-year agreement complements and strengthens Emergent’s mission to protect, enhance, and save lives by helping to reduce opioid overdose deaths —providing compelling product options, combined with a commitment to increasing naloxone access, awareness, and education. There have been great strides in the fight against the opioid epidemic since 2018 when Emergent first acquired its flagship product, NARCAN® Nasal Spray, which is designed to rapidly reverse the effects of a life-threatening opioid emergency.2 A recent report from the Centers for Disease Control and Prevention confirms the number of opioid overdose deaths in the U.S. decreased last year – the first meaningful decline since 2018.3 There are a variety of factors that contributed to this decline; and such progress reinforces the positive impact of Emergent’s comprehensive national strategy and ongoing efforts to increase access to and awareness of available naloxone nasal spray. “The initial signs of progress toward stemming the tide of lives lost to opioid overdose are promising. Emergent’s relentless dedication to working with those on the frontlines of the epidemic, speaking with families and caregivers, and engaging with advocates and other critical stakeholders in the fight, underscores that even one death is too many and our commitment to doing what we can to help remains steadfast,” said Joe Papa, president and chief executive officer, Emergent. “Meeting the needs of our patients and customers by now offering two nasal naloxone products at different strengths – NARCAN® Nasal Spray 4 mg and KLOXXADO® Nasal Spray 8 mg – allows Emergent to do its part to help save lives from this devastating crisis.” Distributing both NARCAN® Nasal Spray 4 mg and KLOXXADO® Nasal Spray 8 mg through Emergent’s expansive distribution networks will provide federal and state leaders, community-based organizations, harm reduction groups, law enforcement and first responders with the flexibility to tailor their approach to opioid overdose reversal treatment for specific patients and communities. NARCAN® Nasal Spray is widely available nationwide over the counter and will continue to be a trusted 4 mg naloxone standard of care in the community setting. With its 8 mg dosage, KLOXXADO® Nasal Spray is a prescription option for those who choose to administer a higher dose of naloxone. “In the midst of responding to an opioid overdose, having access to safe and effective naloxone treatment is paramount, and NARCAN® Nasal Spray 4 mg and KLOXXADO® Nasal Spray 8 mg are proven tools to help reverse the effects of an opioid overdose,” said Dr. Simon Lowry, chief medical officer, Emergent. “Broadening public awareness and expanding access to life-saving naloxone, the current standard of care for opioid overdose reversal, is critical for anyone who may be impacted by the opioid epidemic.” Under the terms of the agreement, Hikma will continue to manufacture KLOXXADO® Nasal Spray 8 mg to maintain distribution and availability. KLOXXADO® Nasal Spray will soon be integrated into Emergent’s proprietary NARCANDirect™ online distribution network where qualified direct purchasers, such as emergency medical services, law enforcement, fire departments, government agencies, schools/universities, and community-based naloxone distribution programs, can purchase and ship bulk quantities.
