Medexus Pharmaceuticals Announces Clear Path to FDA Decision Following medac’s Type A Meeting with FDA on Treosulfan

NDA resubmission expected in second calendar quarter 2022 (previously anticipated timeline)
Final FDA decision expected 2 to 6 months after NDA resubmission
No additional Phase III study is required

TORONTO and CHICAGO, Dec. 02, 2021 (GLOBE NEWSWIRE) -- Medexus Pharmaceuticals Inc. (“Medexus” or the “Company”) (TSX: MDP) (OTCQX: MEDXF) and medac GmbH (“medac”) announced that medac clarified with FDA details with regard to the projected NDA resubmission of treosulfan, an alkylating agent licensed from medac to Medexus, following its Type A Meeting with the U.S. Food and Drug Administration (“FDA”).

medac requested and was granted a Type A Meeting with the FDA, held on November 23, 2021, to review medac’s resubmission plan for its new drug application (“NDA”) for treosulfan and to receive the FDA’s guidance. Resubmission is required because the FDA previously issued a Complete Response Letter following their review of medac’s original treosulfan NDA.

Medexus and medac have reviewed the meeting minutes and the proposed pathway for resubmission. The requirements for marketing authorization were discussed and the companies are diligently working to fulfill those requirements.

Ken d’Entremont, CEO, stated, “We are pleased with the outcome of medac’s productive Type A Meeting with the FDA. We believe this meeting provided medac with the information needed to allow it to resubmit the NDA for treosulfan within our previously anticipated timeframe. Based on the discussions, it is our conclusion that there is a path towards approval that does not involve completing another Phase III study. As a result, we believe that medac will be positioned to resubmit the NDA to the FDA in the second quarter of calendar year 2022. The FDA encouraged medac to maintain open lines of communication and active discussions regarding medac’s resubmission activities.”

Medexus expects the FDA to make a decision regarding approval of treosulfan within two to six months following the resubmission of the NDA. medac will continue to fund the regulatory costs until approval.
