Medexus Strengthens Medical Affairs Team in Preparation for Planned Treosulfan Launch

TORONTO, CHICAGO and MONTREAL, June 10, 2021 (GLOBE NEWSWIRE) -- Medexus Pharmaceuticals Inc. (the “Company” or “Medexus”) (TSXV: MDP) (OTCQX: MEDXF) (Frankfurt: P731) today announced that it has expanded its medical affairs team in preparation for the planned launch of treosulfan, a bifunctional alkylating agent, in the United States.

Treosulfan is an innovative, orphan-designated agent developed for use as part of a conditioning treatment for patients undergoing allogeneic hematopoietic stem cell transplantation (“allo-HSCT”). With more than 100 publications supporting its safety and efficacy, management believes treosulfan is ideally positioned to become the new standard of care in the U.S. As such, pro-actively putting in place the right people and resources ahead of the scheduled Prescription Drug User Fee Act (“PDUFA”) date, which is set for August 2021, is critical to both the successful and timely launch of this innovative product for the benefit of patients and maximizing the value of the seven and a half years of exclusivity the Company expects to receive upon FDA approval. The hires announced today of Keith Steward, MD, MBA, Senior Vice President of Medical Affairs, J. Lynn Bass, B.S, PharmD, Senior Director of Medical Sciences and Mark Fosdal, DHSc, PA-C, Director, Scientific Communications are all part of that pro-active plan.

Ken d’Entremont, CEO, commented, “We expect the launch of treosulfan to be a major milestone for Medexus as it is a truly innovative, best-in-class product that addresses a substantial and underserved market. Before it was genericized in 2016, the current market leading product reached peak annual sales of U.S.$126 million in the United States despite lacking indications for use in patients with AML or MDS.1 Treosulfan is expected to be approved for these indications. For treosulfan, the confirmatory interim analysis of the Phase III Study achieved two-year event-free survival of 64.0% (95% CI 56.0–70.9). This was a marked and statistically significant improvement compared to the busulfan group survival rate of 50.4% (95% CI 42.8–57.5) (HR 0.65 [95% CI 0.47–0.90]); p=0.0000164 (adjusted p-value for testing non-inferiority of treosulfan compared to busulfan)2. To support our expected launch later in 2021, we have put together an exceptional team in all areas of the business. The newly hired Medical Affairs leadership team will immediately be focused on building a field-based Medical Science Liaison team, kicking off our data generation and communication plans, and establishing Medexus as a truly vested partner through extensive outreach with key opinion leaders at transplant Centers of Excellence across the country.”

Keith Steward, MD, MBA, will lead the team as Senior Vice President of Medical Affairs. Mr. Steward has over 20 years of global pharmaceutical and biotech industry experience. Most recently, he served as Global Head of Medical Affairs at QED Therapeutics. He has held several executive and senior level positions throughout his career at companies like EMD (Merck KGaA), Pharmacia and Sanofi-Aventis as well as President/GM for a CME accredited global medical education company. Mr. Steward has significant NDA filing and launch experience for several first-in-class drugs across various therapeutic areas, including oncology and other rare diseases. He also has extensive experience leading multi-departmental organizations focusing on clinical development and medical affairs across multiple therapeutic areas. Dr. Steward received his Medical Degree from Eastern Virginia Medical School in Norfolk, Virginia and completed a Masters in Health Administration from the University of Tennessee, Knoxville.

J. Lynn Bass, B.S, PharmD, joins Medexus as Senior Director of Medical Sciences with over 20 years of experience in field Medical Affairs leadership roles at various pharmaceutical companies, including Eli Lilly, Amgen, Baxter, and Jazz, where her roles included building and managing field medical teams. Her industry career has spanned several therapeutic areas, including Hematology and Stem Cell Transplantation. Most recently Lynn served as Senior Director and Head of Medical Science Liaisons at Mesoblast. Lynn previously worked at Kaiser Permanente and the Department of Defense’s Pharmacoeconomic Center as a Clinical Pharmacist following a career as a clinical microbiologist. Dr. Bass serves as the Chairperson for the global MSL community of the Drug Information Association (DIA) and is a frequent invited speaker on MSL and Medical Affairs related topics.

Mark Fosdal, DHSc, PA-C was hired as Director, Scientific Communications. Dr. Fosdal began his clinical career working as a Physician Assistant at the Fred Hutchinson Cancer Research Center in Seattle while caring for patients undergoing both autologous and allogeneic stem cell transplants. He also participated in running their clinical trials, training visiting physicians, fellows and oncoming staff in managing this population of patients. He has exceptional experience working with indications within hematological malignancies as an MSL and more recently as a Disease Area Lead at Pharmacyclics where he led medical affairs in the cross functional effort in launching of Imbruvica as the first approved drug in treating chronic graft versus host disease. Most recently, Mark served as Executive Medical Science Liaison at Atara Biotherapeutics. Mark received his doctorate in Health Science from Nova Southeastern University and Masters in Hematology/Oncology from the University of Nebraska Medical Center. He also has a bachelor’s degree as a Physician Assistant.
