With two complete response letters in the rearview mirror, Abbvie Inc.’s Vyalev (foscarbidopa/foslevodopa) has been approved by the U.S. FDA for treating Parkinson’s disease. The drug is the first subcutaneous 24-hour infusion of levodopa-based therapy for treating motor fluctuations in adults with advanced disease.
After receiving a complete response letter (CRL) in 2023 related to device issues, North Chicago-based Abbvie Inc. received another CRL for ABBV-951 (foscarbidopa/foslevodopa) for treating motor fluctuations in advanced Parkinson’s disease, this time for issues at a third-party manufacturer.
