Hansa Biopharma Reports Fourth Quarter and Full-Year 2025 Financial Results

• Strong Q4 with 76.0 MSEK in revenue, up 135% from Q4 2024.
• Submission of Biologics License Application (BLA) for imlifidase for highly sensitized patients awaiting kidney transplantation.
• Successfully completed a directed share issue raising 671.5 MSEK (~ $71.3M).

LUND, Sweden, Feb. 11, 2026 /PRNewswire/ — Hansa Biopharma AB, “Hansa” (Nasdaq Stockholm: HNSA), today announced its Q4 2025 and full-year financial results.

Renée Aguiar-Lucander, CEO, Hansa Biopharma, said, “Q4 capped a strong year for Hansa Biopharma. Filing our BLA with the FDA just three months after announcing Phase 3 results highlights the strength of our team and execution focus. We delivered solid growth in Europe, advanced market access efforts, and made the strategic decision to progress our next–generation enzyme HNSA–5487 in Guillain–Barré syndrome, with FDA interactions planned for the first half of 2026. As we enter 2026, our focus is clear: secure FDA approval, ensure a successful U.S. launch of imlifidase, and progress commercial adoption across Europe.”

Financial Performance

Fourth–quarter IDEFIRIX product sales reached 61.1 MSEK, a 139% increase from 25.6 MSEK in Q4 2024. Revenue totalled 76.0 MSEK, representing a 135% increase compared to 32.3 MSEK in Q4 2024.

Full–year 2025 IDEFIRIX product sales amounted to 204.7 MSEK for the full year, a 46% increase from 140.1 MSEK in the previous year. Revenue totalled 222.3 MSEK, representing a 30% increase compared to 171.3 MSEK in 2024. This growth reflects continued adoption across major European markets and underscores both the clinical value of IDEFIRIX, and the momentum Hansa is building in the treatment of highly sensitized patients undergoing kidney transplantation

Pipeline Progress

Imlifidase in Kidney transplantation: In December, Hansa submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for imlifidase in the desensitization of highly sensitized adult patients undergoing deceased kidney donor transplantation. The FDA is currently reviewing the BLA for acceptability and evaluating Hansa’s request for Priority Review, which—if granted—would result in a PDUFA target date in August 2026.

Imlifidase in Gene therapy: Initial data from the first patient in the GNT-018-IDES trial, presented at the European Society of Gene and Cell Therapy, showed that imlifidase rapidly and effectively removed AAV antibodies and can potentially serve as a pre-treatment to enable gene therapy in patients with Crigler–Najjar syndrome who have pre-formed antibodies to the AAV vector. No severe side effects were reported.

HNSA-5487: Hansa is advancing the next-generation enzyme, HNSA-5487, in Guillain-Barré syndrome (GBS). The company is planning for FDA interactions in the first half of 2026, to reach agreement on the clinical development program.
