Nicox S.A. announced that it has received a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) regarding the New Drug Application (NDA) for AC-170, its novel, proprietary, cetirizine eye drop formulation, for the treatment of ocular itching associated with allergic conjunctivitis.
The FDA’s stated reason for the CRL pertains solely to a Good Manufacturing Practice (GMP) inspection at a third party facility producing the active pharmaceutical ingredient (API) cetirizine and supplying it to the manufacturer of the finished product.
Since the receipt of the CRL, Nicox has been contacting its suppliers to assess the timeline for the API manufacturer to address the FDA’s concerns. Once these have been addressed, Nicox will then resubmit the AC-170 NDA.
