FDA Extends Treosulfan NDA Review by 3 Months
Medexus Pharmaceuticals says FDA has extended by three months the review of its Medac licensor’s resubmitted NDA for treosulfan, indicated for combination use with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation. The agency notified Medac that it requires additional time to review supplemental analyses of previously submitted data that had been provided in response to routine information requests, Medexus says. FDA reportedly determined that the additional information constitutes a major amendment, which allows up to three additional months to complete the review, it says, adding that no new clinical data had been requested.
The NDA is seeking treosulfan’s approval for use in adult and pediatric patients with acute myeloid leukemia and myelodysplastic syndromes, Medexus says.
