TORONTO and CHICAGO, Sept. 19, 2022 (GLOBE NEWSWIRE) -- On Friday, September 16, Medexus Pharmaceuticals (Medexus) (TSX: MDP) (OTCQX: MEDXF) was informed by medac, licensor of Medexus’s commercialization rights to treosulfan, that the U.S. Food and Drug Administration (FDA) has delivered to medac a second notice of incomplete response regarding medac’s new drug application resubmission for treosulfan (NDA). The FDA’s notice requests further supporting information from medac to complete medac’s NDA resubmission but does not require submission of new clinical data. Medexus will provide an update to its shareholders and stakeholders once management knows whether the resubmission has been accepted and is better able to assess the impact of this delay.

“While we recognize that the FDA’s response timeline has proven longer than anticipated, we are encouraged to see that the Agency remains engaged with medac to find a path towards resubmission,” commented Ken d’Entremont, Chief Executive Officer of Medexus. “We continue to seek opportunities to collaborate with medac to the extent permitted by our license agreement in order to support medac in satisfying the FDA’s requests and in upholding their responsibility for treosulfan regulatory matters. We are evaluating the potential impact of this delay, including on the timing of a commercial launch in the United States, and we are working with our regulatory and legal advisors to plan accordingly. We firmly believe that treosulfan would make a substantial difference for U.S. patients, as it has in Europe and Canada, and we remain optimistic about the prospect of a treosulfan approval in the United States.”

Mr d’Entremont continued: “We remain focused on delivering strong revenue growth and improved overall performance in our current portfolio of products in both the United States and Canada. We were pleased to announce the strongest fiscal Q1 in our company’s history by delivering a record US$23.0 million of revenue and improved operating performance. Overall, our monthly results so far suggest that we are heading towards another strong quarter.”

Gleolan U.S. sales update

Medexus has now assumed full responsibility for commercializing Gleolan in the United States and has begun shipping Medexus-labeled product to customers across the country. Gleolan sales since March 2022, when Medexus acquired exclusive U.S. commercialization rights, have been in line with Medexus’s expectations, and the company expects to continue that strong performance over the coming months. Medexus previously estimated that Gleolan had generated US$3 million to US$4 million in revenue in the last full quarter before Medexus acquired the exclusive right to commercialize Gleolan in the United States. During the now-completed transition period, Medexus had recognized a portion of total net sales in its revenue, net of an estimated royalty amount. September 2022 will be the first full month in which Medexus recognizes 100% of Gleolan net sales, on which Medexus will pay a tiered annual royalty.

Michael Adelman, General Manager—U.S. Operations, commented: “Completing this seamless transition to full commercialization responsibility is an important accomplishment for patients and customers. We and our partners have worked hard to ensure uninterrupted access to Gleolan and related support programs, and we remain focused on realizing Gleolan’s full potential to improve neurosurgeons’ ability to help high grade glioma patients across the United States and Canada, where Medexus launched Gleolan in February 2021. The institutional sales infrastructure we have built in our U.S. business will serve as a foundation for additional products with similar target accounts.”
