`
`Amphastar Announces the Receipt of a CRL for Intranasal Naloxone for the Emergency
`Treatment of Opioid Overdose
`
`RANCHO CUCAMONGA, Calif., Feb. 21, 2017 (GLOBE NEWSWIRE) -- Amphastar Pharmaceuticals, Inc., (NASDAQ:AMPH)
`announced today that the U.S. Food and Drug Administration ("FDA") issued a Complete Response Letter ("CRL") for its
`New Drug Application ("NDA") for Naloxone Hydrochloride 2mg/0.5mL Nasal Spray ("Intranasal Naloxone"), indicated for the
`emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system
`depression.
`
`The CRL identifies issues including user human factors study, device evaluation, and other items that need to be addressed
`before the NDA can be approved.
`
`Amphastar's CEO, Dr. Jack Zhang, stated: "While we are disappointed to have not received approval at this time, we intend
`to continue to work with the FDA to address their concerns in the CRL and hope to bring Intranasal Naloxone to the market
`as soon as possible."
`
`Deaths from prescription opioids have more than quadrupled since 1999. From 2000 to 2015 more than half a million
`people died from drug overdoses. 91 Americans die every day from an opioid overdose.
`
`Amphastar will continue to offer naloxone in pre-filled syringes while we pursue the NDA for Intranasal Naloxone.
