Amphastar Announces the Receipt of a CRL for Intranasal Naloxone for the Emergency Treatment of Opioid Overdose

RANCHO CUCAMONGA, Calif., Feb. 21, 2017 -- 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.
