Emergent BioSolutions Reinforces Commitment to Opioid Emergency Preparedness Efforts in Canada Through Multi-Year Contract with Ontario Ministry of Health

WINNIPEG, Manitoba, May 01, 2025 (GLOBE NEWSWIRE) -- Today, Emergent BioSolutions Inc. (NYSE: EBS) announced a maximum three-year agreement with a value of approximately $65 million to supply the Ontario Ministry of Health with NARCAN^® Nasal Spray for the Ontario Naloxone Program (ONP). Since 2018, Emergent has supported the Ontario Ministry of Health to provide access to NARCAN^® Nasal Spray across the province. NARCAN^® Nasal Spray is designed to reverse the effects of an opioid poisoning in minutes and is the only 4 mg, intranasal naloxone spray in Canada with a shelf life of four years (48 months).

From January through March 2025, there were 653 suspect drug-related fatalities in Ontario, which is an average of 7 lives lost per day.¹ Data show a promising 30 per cent decrease in overdose deaths from the same period last year.² Opioid poisonings continue to be a significant threat, and therefore, greater access to life-saving medications, such as NARCAN^® Nasal Spray, remain critically important.

"This agreement marks another important step in Emergent's ongoing commitment to addressing opioid poisoning deaths in Canada," said Paul Williams, SVP and products business head, Emergent. "We applaud the Ontario Ministry of Health for their commitment to continuing to ensure access to intranasal naloxone to meet demand. By providing Ontario with NARCAN^® Nasal Spray, we continue to put this life-saving tool in the hands of more people who will now be ready to act in an opioid emergency when every minute counts."

As part of the contract, Emergent will supply the ONP with NARCAN^® Nasal Spray to distribute across the province to individuals at risk of opioid overdose, and their friends and family via participating community-based organizations, including public health units, outreach programs, hospital emergency departments, urgent care and inpatient units, first responders, community health centers and more.

"Our government is helping more people get the treatment and support they need, when and where they need it,” said Sylvia Jones, Ontario Deputy Premier and Minister of Health. “The Ontario Naloxone Program provides people at risk of opioid overdose with access to lifesaving naloxone. We’re pleased to continue working with Emergent to provide intranasal naloxone to those at risk of opioid poisoning and to community members who may have a loved one at risk."

• The signs and symptoms of an opioid overdose emergency can return after KLOXXADO^® is given. If this happens, give another dose after 2 to 3 minutes, using a new KLOXXADO^® device, in the other nostril, and watch the person closely until emergency medical help arrives.
• Do not use KLOXXADO^® if you are allergic to naloxone hydrochloride or any of the ingredients in KLOXXADO^®.
• KLOXXADO^® can cause sudden and severe opioid withdrawal, the symptoms of which may include body aches, diarrhea, rapid heartbeat, fever, runny nose, sneezing, goosebumps, sweating, yawning, nausea or vomiting, nervousness, restlessness or irritability, shivering or trembling, stomach cramps, weakness and high blood pressure.
• KLOXXADO^® is not indicated for pediatric use. In an emergency, if KLOXXADO^® is administered to an infant because no other options are available, they may experience additional withdrawal symptoms such as: seizures, crying more than usual and overactive reflexes. These symptoms may be life-threatening if not treated right away. If KLOXXADO^® is given to an infant, seek immediate medical help.
• Tell your doctor about all of your medical conditions before using KLOXXADO^®, including if you have heart disease or any other heart problems, are pregnant or think you are pregnant, or are breastfeeding or plan to breastfeed.
