The third time proved the charm for Adamis Pharmaceuticals Corp.’s high-dose naloxone injection, Zimhi, which gained FDA approval for use in treating opioid overdose, nearly three years after the San Diego-based company first submitted an NDA.
Shares of San Diego-based Adamis Pharmaceuticals Corp. (NASDAQ:ADMP) fell 51% to close Monday at 62 cents after the FDA issued a complete response letter regarding its high-dose naloxone injection candidate, Zimhi, for the treatment of opioid overdose. The agency raised questions about chemistry, manufacturing and controls (CMC), but not the candidate's safety or efficacy, the company said.
