Unlocking Transplant Opportunities with Hansa Biopharma's Imlifidase Breakthrough at ATC 2024
LUND, Sweden, May 21, 2024 -- Hansa Biopharma ("Hansa"), a trailblazing biopharmaceutical entity, has declared an exciting line-up of presentations covering imlifidase to occur during the prestigious American Transplant Congress (ATC). The ATC serves as a converging venue for experts from the American Society of Transplant Surgeons (ASTS) and the American Society of Transplantation (ATS). Imlifidase, Hansa's signature antibody-cleaving enzyme, meticulously targets the IgG antibodies to curtail IgG-mediated immune responses.
Søren Tulstrup, the CEO and President of Hansa Biopharma, voices the company's anticipation of ATC as an excellent stage for unveiling vital scientific data and for spotlighting imlifidase's potential in expediting transplant possibilities for hypersensitized patients. The company's participation in the ATC underscores its unwavering dedication to pioneering novel approaches in the realm of transplant care, with the aim of bringing transformative treatments to the fore.
Currently, imlifidase holds a conditional marketing authorization in Europe under the commercial name IDEFIRIX®, designated for the desensitization treatment of hypersensitized adults in need of a kidney transplant from a deceased donor with whom they have a positive crossmatch. Hansa is actively engaging in a Phase 3 trial in the US, with the strategic plan to request approval for a Biologic License Application (BLA) from the US Food and Drug Administration (FDA) in 2025. Furthermore, its utility is also being explored in the context of pre-treatment for gene therapy in patients with rare diseases who harbor pre-existing antibodies, and also in several autoimmune disorders, such as anti-GBM and Guillain-Barre Syndrome (GBS).
At the core of the ATC meetings are key abstracts that embody the innovative strides Hansa Biopharma is taking:
Restoration of COVID-Specific IgG Antibodies Post-Imlifidase Treatment: Discovering immunity regain post-therapy.
Probing a Phase II Study on DSA Reappearance in Hypersensitized Living Donor Kidney Recipients Post-Imlifidase Treatment: Unraveling the dynamics of antibody surge following treatment.

Highly sensitized patients, burdened by pre-formed antibodies known as donor-specific antibodies (DSAs) against human leukocyte antigens (HLAs), often face the dire risk of tissue damage and potential transplant rejections. The complex immunological profiles these patients possess result in prolonged periods on transplant waiting lists and a correlating increase in mortality risk. In Europe and the United States, approximately 10-15% of individuals on transplant waiting lists fall into this hypersensitized category.
Originating from Streptococcus pyogenes, imlifidase is a revolutionary antibody-cleaving enzyme capable of selectively targeting and breaking down IgG antibodies, thus impeding the IgG-mediated immune responses. With a swiftly efficient mechanism, imlifidase commences its antibody-cleaving capabilities shortly after administration. In Europe, IDEFIRIX® is granted conditional marketing consent for desensitizing highly sensitized adult kidney transplant candidates facing positive crossmatches with available deceased donors. Its strategic use is prioritized for patients who otherwise have bleak chances of transplantation under existing kidney allocation systems, even after considering prioritization programs for hypersensitized individuals. Reviewed under the European Medicines Agency's PRIME program, IDEFIRIX® has been identified to potentially confer a significant therapeutic advantage or serve patients without alternative treatments.
This antibody-cleaving enzyme has emerged as an innovative strategy for the desensitization of transplant candidates, who have preformed anti-HLA donor-specific antibodies (DSAs); these antibodies, if left unchecked, can bind and damage the transplanted organ. By inactivating these, imlifidase opens a critical timeframe in which transplants can be carried out—just before the body begins producing new IgG antibodies, at which point post-transplant immunosuppression is in effect to help stave off organ rejection. The potent efficacy of imlifidase as a pre-transplant treatment to diminish IgG was examined across four phase 2 clinical trials. Hansa is determined to supply additional clinical evidence, including data from an observational follow-up study and a post-approval efficacy study.

Progressing nephropathy culminating in kidney failure, or End-Stage Renal Disease (ESRD), manifests when a patient's renal function deteriorates to below 15%. The toll it takes on health is substantial, with close to 2.5 million individuals globally affected. Opting for a kidney transplant generally results in improved survival rates, enhances quality of life, and is more economical compared to prolonged dialysis treatments. In the European Union and the United Kingdom alone, an estimated 80,000 patients with kidney ailments are on the waiting list for a transplant.
At the frontier of clinical-stage biopharmaceutical innovation, Hansa Biopharma is dedicated to developing and commercializing life-changing therapies for individuals grappling with rare immunological afflictions. Hansa's leading-edge IgG antibody-cleaving enzyme therapy has been pivotal in making kidney transplantation a reality for hypersensitized patients. With an extensive and burgeoning R&D platform grounded on proprietary IgG-cleaving enzyme technology, the company is earnestly addressing the critical medical needs in transplantation, autoimmune diseases, gene therapy, and cancer. Headquartered in Lund, Sweden, with activities spanning across Europe and the United States, Hansa Biopharma proudly trades on Nasdaq Stockholm under the ticker HNSA.
