Complete Response Letter Received from FDA for Treosulfan

Complete Response Letter Received from FDA for Treosulfan

TORONTO and CHICAGO and WEDEL, Germany, Aug. 03, 2021 (GLOBE NEWSWIRE) — Medexus Pharmaceuticals Inc. (“Medexus” or the “Company”) (TSX: MDP) (OTCQX: MEDXF) and medac GmbH (“medac”) announced today that medac, Medexus’ licensor for treosulfan, has received a Complete Response Letter (CRL) from the Food and Drug Administration (FDA) in response to its New Drug Application (NDA) for treosulfan.

As previously disclosed, the NDA was submitted for use of treosulfan in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT), and both Medexus and medac had been optimistic that a positive decision from the FDA in connection with a planned Prescription Drug User Fee Act (“PDUFA”) date on August 11th would allow for a commercial launch of treosulfan in U.S. later this year.

However, as expressed in the CRL, the FDA has determined that it cannot approve the NDA in its present form and has provided recommendations specific to additional clinical/statistical data and analyses pertaining to the primary and secondary endpoints of the completed pivotal Phase III study. Medexus and medac are reviewing the letter to determine the appropriate course of action. Medexus and medac will work closely with the FDA to understand and address their comments.

Ken d’Entremont, CEO, commented, “Given the recent Health Canada approval, European Medicines Agency approval in 2019, as well as supporting data from more than 100 publications, we were all surprised by the FDA’s response. That being said, Medexus and medac look forward to continuing to work with the FDA to address their requests in a timely manner, and we remain optimistic for a future, albeit delayed, approval of treosulfan in the United States, complete with Orphan Drug Designation. The current standard of care is not suitable for numerous at-risk groups, due to the high toxicity effects, and treosulfan has demonstrated excellent survival data among those groups. We are hopeful that our future communications with the FDA will result in a positive outcome, and we look forward to providing further updates in due course.”

Michael Adelman, General Manager of U.S. Operations, commented, “We have been working diligently with medac to prepare for the approval of treosulfan and launch shortly thereafter. We are disappointed with the immediate result, but are encouraged by an incredible amount of support from key opinion leaders and the medical community for use of treosulfan in the United States. With the extensive launch preparations we have taken to date, we are well positioned to meet the expected strong demand for treosulfan. While we work to address all of the FDA’s requests, we stand poised to execute our comprehensive launch plan for treosulfan upon approval.”
