CRL for AbbVie’s Parkinson’s disease drug
AbbVie Inc has received a complete response letter (CRL) from the US Food and Drug Administration requesting additional information on a pump that is used to deliver its candidate treatment for Parkinson’s disease, the company announced on 22 March. A CRL is a formal notice from the FDA to a company outlining deficiencies in a new drug application (NDA). The agency did not request additional safety or efficacy studies. AbbVie said it plans to resubmit its regulatory application as soon as possible.
