AbbVie NDA for Parkinson’s Drug Approved
FDA has approved an AbbVie NDA for Vyalev (foscarbidopa and foslevodopa), which is described as the first subcutaneous 24-hour infusion of levodopa-based therapy for treating motor fluctuations in adults with advanced Parkinson's disease.
In June, the agency had issued a second complete response letter (CRL) on the NDA and cited observations that were identified during an inspection of a third-party manufacturer listed in the submission, the company says, adding that the inspection at the facility did not involve ABBV-951 or any other AbbVie drug. The first CRL was issued 3/23 and it requested additional information about the product’s device (pump), the company said at the time, adding that there were no requests to conduct additional efficacy and safety trials related to the drug (see earlier story).
The approval was supported by data from the company’s Phase 3, head-to-head, controlled clinical trial demonstrating statistically significant improvement in “on” time without troublesome dyskinesia compared to oral immediate-release carbidopa/levodopa, AbbVie says.
Regarding safety, the company says the majority of adverse reactions (ARs) were non-serious and mild or moderate in severity. The most frequent ARs were infusion site events, hallucinations, and dyskinesia.
ABBV-951 is designed to provide 24-hour, continuous subcutaneous delivery of carbidopa/levodopa prodrugs. “Compared to oral CD/LD, it offers the potential for improvement in motor fluctuations in patients with advanced Parkinson's disease, a progressive and chronic neurological disorder resulting from the loss of dopamine-producing brain cells, which primarily manifests with tremor, muscle rigidity, slowness of movement and difficulty with balance,” AbbVie says.
