Medexus Pharmaceuticals Announces Resubmission of Treosulfan NDA
Additional data collection and analysis reconfirms confidence in New Drug Application for Treosulfan
NDA resubmission date consistent with previously announced timeline
FDA decision still expected within six months of resubmission
TORONTO and CHICAGO, April 22, 2022 (GLOBE NEWSWIRE) -- Medexus Pharmaceuticals (Medexus) (TSX: MDP) (OTCQX: MEDXF) and medac, a strategic partner of Medexus, are pleased to announce that medac has resubmitted its New Drug Application for Treosulfan (NDA) with the U.S. Food and Drug Administration (FDA). The NDA requests approval of Treosulfan in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT). The resubmission includes additional clinical data and statistical analysis relating to the previously-completed phase 3 clinical trial of Treosulfan as well as an update of the integrated summary of safety, which the FDA had requested in their July 2021 Complete Response Letter to medac.
“medac’s comprehensive data collection and analysis reconfirmed our confidence in the results of the phase 3 study, and we are pleased that the FDA will have an opportunity to review this additional information,” commented Ken d’Entremont, Medexus’s Chief Executive Officer. “Within 30 days of resubmission, the FDA will communicate the timeline for their review. We and our partners at medac look forward to an FDA decision within six months from resubmission. An FDA approval would then pave the way for a commercial launch of Treosulfan in the United States within Medexus’s fiscal year 2023.”
Michael Adelman, Medexus’s General Manager, U.S. Operations, commented further: “Treosulfan is orphan drug designated and, if approved, would be the first in a new conditioning treatment class for allo-HSCT Reduced Toxicity Conditioning – providing patients and their physicians with a unique combination of improved survival outcomes compared to reduced-intensity regimens and decreased toxicity compared to standard myeloablative regimens.”
Mr. Adelman continued, “During the extended registration period, we have continued to work diligently with our partners at medac to further prepare for the launch of Treosulfan in the United States. We stand ready to execute our comprehensive launch plan upon approval. We are very hopeful for a favorable FDA decision and believe that, if approved, Treosulfan will become the new standard of care for patients with acute myeloid leukemia and myelodysplastic syndrome undergoing allo-HSCT in North America.”
