“2025 was a transformational year for Cantargia. We secured commercial validation of our IL1RAP platform through a major partnership with Otsuka Pharmaceutical, achieved FDA Fast Track Designation for nadunolimab in our lead PDAC indication, strengthened our leadership team with world-class expertise, and continued to advance our precision medicine strategy on the basis of robust biological and clinical evidence. As I write this first annual letter to you as CEO, I do so with pride in what we have accomplished and confidence in what lies ahead.”, said Hilde Steineger, CEO of Cantargia AB.

About Cantargia
Cantargia AB (publ), reg. no. 556791-6019, is a biotechnology company that develops antibody-based treatments for life-threatening diseases and has established a platform based on the protein IL1RAP, involved in a number of cancer forms and inflammatory diseases. Cantargia’s oncology program, the antibody nadunolimab (CAN04), is being studied clinically, primarily in combination with chemotherapy with a focus on pancreatic cancer and non-small cell lung cancer. Positive data for the combinations indicate stronger efficacy than would be expected from chemotherapy alone. Cantargia’s second development program, the antibody CAN10, blocks signaling via IL1RAP in a different manner than nadunolimab and addresses treatment of serious autoimmune/inflammatory diseases. In September 2025, the acquisition of CAN10 by Otsuka Pharmaceutical was completed.

Cantargia is listed on Nasdaq Stockholm (ticker: CANTA). More information about Cantargia is available at www.cantargia.com.
