The US Food and Drug Administration has issued a complete response letter (CRL) to Eli Lilly and Company for its application for an accelerated approval of the investigative treatment for Alzheimer’s disease donanemab. A CRL is a formal notice to a company in which the agency explains why it cannot accept an application for a drug approval, usually citing deficiencies in the application itself. Donanemab is a monoclonal antibody that targets beta amyloid plaque in the brain for the treatment of patients with early symptomatic Alzheimer’s disease.
