Medexus Successfully Completes Agreement for Public Reimbursement of Trecondyv (treosulfan for injection) in Quebec, Canada

Toronto, Ontario and Chicago, Illinois--(Newsfile Corp. - April 17, 2025) - Medexus Pharmaceuticals (TSX: MDP) (OTCQX: MEDXF) recently completed a listing agreement with the provincial government of Quebec for Trecondyv® (treosulfan for injection). The Public Prescription Drug Insurance Plan of the Régie de l’Assurance Maladie du Québec, or RAMQ, will now reimburse eligible claims made for Trecondyv®.*

“This development is another important reimbursement milestone for Trecondyv® because we have now achieved public reimbursement of Trecondyv® in Canada’s three most populous provinces, representing around three quarters of Canadians,” said Richard Labelle, Medexus’s Chief Operating Officer. “It further demonstrates our commitment to seeking and quickly achieving public reimbursement across Canada, and is yet another important indicator of the prospects and potential of our treosulfan products – both Trecondyv® in the Canadian market and, in the US market, GRAFAPEX™ (treosulfan) for Injection.”

The next step in the Trecondyv® public reimbursement process will be for other remaining government organizations to make their respective final decisions on public reimbursement for their regions or jurisdictions. Medexus is committed to continuing to work with these other participating provincial, territorial, and federal government organizations to make Trecondyv® available as soon as possible through public drug plans for the patients who need it.

About Trecondyv® (treosulfan for injection)

Trecondyv® (treosulfan for injection) is part of a preparative regimen for allogeneic hematopoietic stem cell transplantation, to be used in combination with fludarabine, used in treating eligible patients with acute myeloid leukemia and myelodysplastic syndromes.

Final study results and analysis of the pivotal phase 3 clinical trial of treosulfan conducted by medac GmbH, which was published in the American Journal of Hematology, concluded that the study demonstrates clinically relevant superiority of treosulfan over a widely applied “reduced-intensity conditioning” busulfan regimen with regard to its primary endpoint, event-free survival. The publication also includes favorable conclusions on two key secondary endpoints, finding that overall survival with treosulfan was superior compared to busulfan and that non-relapse mortality for patients in the treosulfan arm was lower than for patients in the busulfan arm. For more information about the study and the publication, including a link to the full publication, see Medexus’s June 6, 2022 press release, available via the Investors section of Medexus’s corporate website.

During the phase 3 clinical trial of treosulfan, treatment emergent adverse events (TEAEs) were most commonly reported in the system organ classes, or SOCs, of “Gastrointestinal disorders”, “General disorders and administration site conditions”, and “Musculoskeletal and connective tissue disorders”. TEAEs of at least CTCAE Grade III were reported by 54.8% of patients in the treosulfan treatment group. Severe adverse events were reported by 8.5% of patients in the treosulfan treatment group. Overall, TEAEs were reported by 92.6% of patients in the treosulfan treatment group.

In addition, specific risks and uncertainties relevant to the content of this news release include, among other things: the uncertainties inherent in research initiatives (including the possibility of unfavorable new data and further analyses of existing data); the risk that data are subject to differing interpretations and assessments by relevant third parties; and whether relevant third parties will be satisfied with the design and methodology of and results from the relevant study, which will depend on many factors, including determinations as to whether the product’s benefits outweigh its known risks and determinations of the product’s efficacy and cost-effectiveness in the context of a given facility (which varies by facility type). Further such risks and uncertainties include, among other things, risks and uncertainties associated with the legislative, regulatory, and policy environment in the markets and jurisdictions in which the company does business, and, in general, the evolving international trade situation in respect of tariffs or restrictions on or otherwise affecting pharmaceutical or biologic products, including the company’s products or components of those products.
