FDA Delays Clinical Hold Review on Neurizon ALS Drug
FDA has extended until 10/3 its review of a clinical hold response from Neurizon Therapeutics’ NUZ-001, its lead experimental treatment for amyotrophic lateral sclerosis (ALS). The agency’s standard review period for such responses is 30 days, but Neurizon said the delay stems from FDA-wide staffing cuts and restructuring under recent administrative reforms. Those changes have created review backlogs across multiple divisions, affecting other ALS programs as well, the company says , adding that earlier this year Coya Therapeutics also faced an FDA IND delay on its ALS drug COYA-302 due to internal workload pressures.
“This delay is extremely disappointing — particularly given the straightforward nature of the information provided in our response,” said Neurizon CEO Michael Thurn. “We remain confident in the potential of NUZ-001 as a transformative therapy for ALS and are working with U.S. experts and patient groups to advocate for an expedited review.”
