Complete Response for regulatory review of Ultomiris in the treatment of adult patients with neuromyelitis optica spectrum disorder
The FDA has issued a complete response letter (CRL) regarding the supplemental Biologics License Application (sBLA) for long-acting C5 complement inhibitor Ultomiris (ravulizumab-cwvz) for the treatment of adult patients with neuromyelitis optica spectrum disorder (NMOSD) who are anti-aquaporin-4 (AQP4) antibody positive (Ab+)
The CRL did not request additional analysis or reanalysis of the Phase III CHAMPION-NMOSD trial data included in the sBLA submission and did not raise concerns about the efficacy or safety data from the trial. The FDA requested modifications to enhance the Ultomiris Risk Evaluation and Mitigation Strategy (REMS) to further validate patients’ meningococcal vaccination status or prophylactic administration of antibiotics prior to treatment.
Alexion, AstraZeneca Rare Disease is working closely with the FDA regarding next steps for the REMS modifications and remains committed to bringing Ultomiris to people living with NMOSD in the US as quickly as possible.
