Press Release

Stockholm, Sweden, November 8, 2024

“In the third quarter of 2024, Mendus has focused on expanding the clinical development for vididencel in acute myeloid leukemia (AML) and progressing the program toward pivotal-stage readiness. We have worked closely with the Australasian Leukaemia and Lymphoma Group (ALLG) to open the first clinical centers for the AMLM22-CADENCE trial, which will evaluate vididencel in combination with oral azacitidine as a maintenance therapy for AML patients. In parallel, we are preparing vididencel for pivotal-stage development, the final development stage before market registration. Next to more extensive interactions with regulatory agencies, these preparations involve the implementation of large-scale manufacturing and our manufacturing collaboration with NorthX Biologics has remained on track in Q3. In July, Mendus closed an alliance with Institut Bergonié to study the intratumoral immune primer ilixadencel in soft tissue sarcoma, a hard-to-treat solid tumor, as part of the REGOMUNE combination trial with avelumab and regorafenib. The preparations for the trial are ongoing and to be completed in Q4. Our preclinical research continues to focus on supporting the clinical programs, with multiple abstracts related to vididencel and ilixadencel to be presented at the upcoming SITC and ASH conferences. Also in Q4, we expect topline safety and feasibility data from all patients treated in the ALISON Ph 1 trial studying vididencel in ovarian cancer. Finally, updated survival data from the ongoing ADVANCE II trial with vididencel in AML will be presented on December 8, during the ASH conference. Mendus will publish a press release summarizing the data on Monday morning, December 9 at 8am CET.”
