“The first quarter of 2026 reflects both strong execution and important strategic progress for Cantargia. We have delivered promising early clinical data in MDS, advanced our pipeline, and taken decisive steps to position the Company for increased long-term value creation in a rapidly evolving treatment landscape.”, said Hilde Steineger, CEO of Cantargia.

Significant events in the first quarter

• New preclinical data on anti-tumor effects of nadunolimab in metastatic colorectal cancer were presented at the Keystone Cancer Immunotherapy conference.

Significant events after the end of the period

• The study design and scientific rationale for the investigator-initiated Phase 1b/2a study of nadunolimab in combination with checkpoint inhibitors in microsatellite-stable (MSS) colorectal cancer were presented at AACR 2026.
• Early but highly encouraging data were presented from the ongoing investigator-initiated Phase 1b/2a study evaluating nadunolimab in higher-risk myelodysplastic syndrome (HR-MDS) and acute myeloid leukemia (AML), including complete remission in all HR-MDS patients evaluated to date, leading to initiation of a formal hematological malignancies program.
• In view of exciting new Phase 3 data in PDAC from Revolution Medicine’s RAS inhibitor, we see a clear opportunity to enhance value by rethinking the timing and structure of the planned Phase 2b/3 PDAC study for nadunolimab so that a future pivotal program is taking full advantage of the new RAS inhibitor driven treatment landscape.
• Dr. Wolfram Dempke will transition from the role of Chief Medical Officer and continue to support Cantargia as Chair of our PDAC Scientific Advisory Board
