Mendus AB announced that it has received Fast Track Designation from the U.S. Food and Drug Administration (FDA) for the Company's lead program, vididencel, for the treatment of Acute Myeloid Leukemia (AML) in complete remission with residual disease. Advantages of the Fast Track Designation include close and early interactions with the FDA to support accelerated approval, as well as the possibility of a "rolling review" for a subsequent market application. The FDA's decision was based on the previously communicated results from the ADVANCE II clinical trial, which delivered promising survival read-outs and underpinned the safety of vididencel as a monotherapy in AML.

Vididencel had already been assigned Orphan Drug Designation for treatment of AML in the US and Europe. Additionally, Mendus had recently been granted an Advanced Therapy Medicinal Product (ATMP) certificate by the European Medicines Agency (EMA) following a review of manufacturing quality and non-clinical data for its lead pipeline program vididencel.ididencel is currently being evaluated in AML and ovarian cancer as a potential maintenance therapy to reduce or prevent tumor recurrence. Vididencel is an off-the-shelf, intradermal vaccine derived from the Company's proprietary DCOne leukemic cell line.

In December 2022, the Company presented positive results from the ADVANCE II study in AML at the American Society of Hematology (ASH) Annual Meeting. The analysis demonstrated the potential of vididencel to control measurable residual disease (MRD) and induce durable relapse-free survival in the majority of patients. Mendus expects to present a next survival update in the fourth quarter of 2023.

Additionally, Mendus anticipates to start a new Phase 2 clinical trial evaluating a combination of vididencel with oral azacitidine (Onureg®, the current standard of care in AML maintenance) in H2 2023, as a step-up to pivotal-stage development.
