LUND, Sweden I October 7, 2024 I Hansa Biopharma AB, (“Hansa” or the “Company”) (NASDAQ STOCKHOLM: HNSA), today announced positive results from a 12-month follow up analysis from the NICE-01 trial of HNSA-5487, the Company’s next generation immunoglobulin G (IgG)-cleaving molecule, assessing IgG recovery, immunogenicity and redosing potential. In the NICE-01 trial, HNSA-5487 demonstrated rapid and highly robust reduction of IgG levels by more than 95 percent within a few hours post treatment. In a 12-month follow up analysis IgG levels returned to normal range six months after initial dosing. This confirms that HNSA-5487 mirrors the extremely high efficacy of imlifidase, the Company’s first-generation IgG-cleaving enzyme, in reducing total IgG levels. No serious adverse events were observed and as previously communicated HNSA-5487 is safe and well tolerated. Importantly, HNSA-5487 demonstrated lower pre-treatment anti-drug antibody (ADA) levels and significantly reduced ADA responses when compared to imlifidase, confirming an attractive immunogenicity profile with a clear redosing potential. HNSA-5487 also demonstrated highly robust reduction in IgG levels with similar efficacy in nearly 100 percent of serum samples collected in the trial and analyzed at six- and 12-months after the initial dose. Søren Tulstrup, President and CEO, Hansa Biopharma said, “There is mounting clinical evidence that faster and more robust IgG reduction is directly linked to more successful therapeutic outcomes in autoimmune and other diseases. We are very encouraged by these results that demonstrate HNSA-5487 can robustly and very rapidly reduce IgG levels, has redosing potential, and a favorable safety and tolerability profile. We believe HNSA-5487 has a highly differentiated profile compared to published data from studies with other IgG-targeted therapies. These results underscore the transformational potential of HNSA-5487 to address significant unmet need across a spectrum of IgG driven diseases and conditions, including autoimmune where there is a clear need for better management of initial and repeat immune system attacks.” The Company will focus clinical development of HNSA-5487 in chronic autoimmune diseases where IgG plays a role in disease pathology and acute phases. Initial clinical development of HNSA-5487 will focus in myelin oligodendrocyte glycoprotein antibody disease (MOGAD), neuromyelitis optica (NMO) and myasthenia gravis (MG). MOGAD affects 2 – 3.4 in every 100,000 people worldwide and approximately 30 percent of all cases are in children. 1 NMO affects approximately seven in every 100,000 people in the US and approximately 22,000 people in the US are living with the condition. 2 Globally, approximately 150 to 200 out of every million people have MG. 3 These conditions have a common underlying cause: misguided IgG antibodies. Despite the serious nature of these diseases, unmet medical need remains high with few advanced therapies available, and no treatments approved for the acute phases. HNSA-5487 can effectively and quickly reduce IgG levels, potentially addressing a diverse range of debilitating symptoms caused by these conditions. NICE-01 is a double blind, randomized, placebo-controlled trial evaluating safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of single ascending doses of HNSA-5487 administered as a single intravenous (IV) infusion. The trial included a total of 36 healthy male and female adult participants. There were no serious adverse events and as previously communicated HNSA-5487 was safe and well tolerated. Notes to editors About HNSA-5487 and the Novel IgG Cleaving Enzyme for Repeat Dosing (NiceR) Program HNSA-5487 is Hansa Biopharma’s next-generation IgG-cleaving enzyme with the potential to prolong the IgG-low window. In 2023, Hansa conducted the first-in-human trial of HNSA-5487 (NICE-01) reporting positive high-level results on safety and tolerability and observing complete depletion of IgG antibodies at increasing doses. NiceR is Hansa Biopharma’s next generation IgG-cleaving enzyme program. It is in preclinical development and is designed to enable expansion into a large spectrum of potential indications, including relapsing autoimmune diseases and gene therapy, as well as oncology indications. The lead molecule in the NiceR program is HNSA-5487. About imlifidase Imlifidase is an antibody-cleaving enzyme originating from Streptococcus pyogenes that specifically targets and cleaves immunoglobulin G (IgG) antibodies and inhibits IgG-mediated immune response. 4 It has a rapid onset of action, cleaving IgG-antibodies and inhibiting their activity within hours after administration. Imlifidase has conditional marketing approval in Europe and is marketed under the trade name IDEFIRIX ® for the desensitization treatment of highly sensitized adult kidney transplant patients with a positive crossmatch against an available deceased donor. The use of IDEFIRIX should be reserved for patients who are unlikely to be transplanted under the available kidney allocation system, including prioritization programs for highly sensitized patients. 4 IDEFIRIX was reviewed as part of the European Medicines Agency’s (EMA) Priority Medicines (PRIME) program, which supports medicines that may offer a major therapeutic advantage over existing treatments or benefit patients without treatment options. 4 The efficacy and safety of imlifidase as a pre-transplant treatment to reduce donor-specific IgG was studied in four phase 2 open-label, single-arm, six-month clinical trials. 5,6,7 Hansa is collecting further clinical evidence and will submit additional efficacy and safety data based on one observational follow-up study and one post-approval efficacy study. Full product information can be accessed via the initial Summary of Product Characteristics found here . About Myelin Oligodendrocyte Glycoprotein Antibody Disease (MOGAD) MOGAD is an inflammatory disorder of the central nervous system characterized by attacks of immune-mediated demyelination predominantly targeting the optic nerves, brain, and spinal cord. 8 It is associated with the presence of antibodies directed against myelin oligodendrocyte glycoprotein (MOG). MOG is found in the myelin that insulates the nerves of the central nervous system, which consists of the brain, spinal cord and optic nerves. The antibody attack on MOG disrupts the transmission of nerve signals in the body and causes a variety of symptoms including changes in vision, weakness and numbness of the limbs, and paralysis. 9 MOGAD affects 2 – 3.4 in every 100,000 people worldwide and approximately 30 percent of all cases are in children. 1 About Neuromylelitis Optica (NMO) NMO is a rare autoimmune disease of the central nervous system (CNS) that mainly affects the optic nerves and spinal cord. It is sometimes referred to as NMO spectrum disorder or NMOSD. In NMO, the body’s immune system mistakenly attacks healthy cells and proteins in the body, most often those in the spinal cord and eyes. Symptoms include eye pain and vision loss, weakness or paralysis of arms and legs, and severe vomiting and nausea. There is no cure for NMO, and relapses and attacks are often treated with corticosteroid drugs and plasma exchange. 10 NMO affects approximately seven in every 100,000 people in the US. About 22,000 people in the US are living with the condition. 2 About Myasthenia Gravis (MG) MG is a rare, chronic autoimmune neuromuscular disorder that is characterized by fluctuating weakness of the voluntary muscle groups. Approximately half of all people with MG will experience weakness in the eye (ocular) muscles first, which can include double vision, blurred vision and drooping eyelids. Eight out of 10 people with MG will develop more widespread weakness including in the neck, face, arms or legs. 11,12 Current immunomodulatory treatments do not achieve sufficient improvement or resolution of symptoms and more targeted therapies are needed. 13 Globally, approximately 150 to 200 out of every million people have MG. In the US it is estimated that 37 out of every 100,000 people have MG. 3 About Hansa Biopharma Hansa Biopharma is a pioneering commercial-stage biopharmaceutical company on a mission to develop and commercialize innovative, lifesaving and life-altering treatments for patients with rare immunological conditions. Hansa Biopharma has developed a first-in-class immunoglobulin G (IgG) antibody-cleaving enzyme therapy, which has been shown to enable kidney transplantation in highly sensitized patients. Hansa Biopharma has a rich and expanding research and development program based on the Company’s proprietary IgG-cleaving enzyme technology platform, to address serious unmet medical needs in transplantation, autoimmune diseases, gene therapy and cancer. Hansa Biopharma is based in Lund, Sweden, and has operations in Europe and the U.S. The company is listed on Nasdaq Stockholm under the ticker HNSA.

LIEGE, BELGIUM / ACCESSWIRE / September 13, 2023 / Imcyse a clinical-stage biopharmaceutical company pioneering the development of a new class of active and specific immunotherapies for the treatment of severe autoimmune diseases, today announced completion of enrollment and initial dosing in the Phase 1 portion of its adaptive Phase 1/2 clinical trial, IMCY-MS-001. The Phase 1 open-label, dose escalation part of the study is assessing the safety of three doses of Imotope™ IMCY-0141 in patients with relapsing-remitting multiple sclerosis (RRMS). "Completing enrollment in the Phase 1 trial with IMCY-0141 is an important step towards bringing this therapy to patients suffering from RRMS, a disease with devastating and often unpredictable symptoms," said Denis Bedoret, CEO of Imcyse . "IMCY-0141 is now the second Imotope™ from Imcyse's proprietary platform to progress to the next clinical stage, demonstrating our commitment to finding new therapies for patients suffering from severe, chronic autoimmune diseases." Jean Van Rampelbergh, CCDO of Imcyse , added: "The pre-specified Independent Data Monitoring Committee analyses to date have found no safety concerns, and we expect the final outcome of the IDMC's review of the data from the third and highest dose level from our Phase 1 trial by the end of this year. The results from the Phase 1 portion of the trial will allow further refining of the Phase 2 protocol design and selection of the most appropriate doses to be evaluated. We look forward to continuing to explore the role of IMCY-0141 in the treatment of multiple sclerosis, which, if applied early-on in the course of disease, could slow down or even halt its progression, leading to a potentially curative approach." IMCY-0141 is being evaluated in an ongoing Phase 1/2 trial, IMCY-MS-001, in adult patients with RRMS. Following the Phase 1 dose escalation portion, the Phase 2 expansion arm of the trial will be designed to assess immune responses, while continuing to evaluate disease marker activity. In addition, it will allow for dose optimization in preparation for registration studies. For more information on this clinical trial, please visit: , NCT05417269. ABOUT IMCY-0141 IMCY-0141 is the Company's second clinical-stage compound. This Imotope™ is designed based on MOG (Myelin Oligodendrocyte Glycoprotein) with the aim to halt the progression of multiple sclerosis (MS) by stopping the body's immune system from attacking the central nervous system and disrupting undesirable autoimmune responses that drive the destruction of the myelin sheath protecting the nerves. IMCY-0141 has shown promising results in several MS preclinical models, demonstrating an immune response that supports the proposed mode of action and inducing a memory response so that the treatment effect is long-lasting and requires less frequent dosing regimens. Also, if treatment is begun early enough, it has the potential to allow patients to live with minimal impact from the disease. ABOUT MULTIPLE SCLEROSIS (MS) Multiple sclerosis (MS) induces damage to the proteins protecting the nerves, also called nerve sheath demyelination, which exposes the underlying nerves and can lead to paralysis. Symptoms include muscle weakness, weak reflexes, tremors, and muscle spasms. More than three million people globally have been diagnosed with MS. The disease can affect people as young as 15 years old, and women are twice as likely as men to contract MS. The true cause of the disease is unknown; however, a combination of hereditary and environmental factors is believed to enable the autoimmune attack. There is no cure for MS. MS treatments typically focus on speeding recovery from attacks, slowing disease progression and managing symptoms. Although current medications are effective in reducing the frequency of disease relapse, they are also associated with significant side effects and compliance challenges. Thus, there remains a major need for new treatments with a more favourable safety pro can slow or even stop disease progression. ABOUT IMCYSE Imcyse is a clinical-stage biopharmaceutical company pioneering the development of a new class of active specific immunotherapies for the treatment of severe chronic autoimmune diseases. The Company's unique technology platform allows the local targeting of immune cells involved in the destruction of the diseased organ. This platform is based on the administration of Imotopes™, which are synthetic peptides encompassing a T-cell epitope and an active thioredox motif. Imotopes™ generate cytolytic CD4 T-cells that specifically eliminate autoantigen-presenting cells and autoantigen-specific lymphocytes involved in the disease pathways. Imcyse's approach, sustained over time, may help to prevent and treat diseases with no current therapeutic options and to potentially cure patients without impairing their immune defenses. The Company has established proof of concept in several indications, has completed its first clinical trial in type 1 diabetes with promising results and is expecting top-line data from the fully enrolled Phase 2 study in this indication in 2024. A Phase 1/2 clinical trial in multiple sclerosis (MS) was initiated in April 2022. Beyond type 1 diabetes and MS, Imcyse is developing a pipeline of Imotopes™ for the treatment of several autoimmune diseases in large and rare disease indications. Imcyse was founded as a spin-off from the Catholic University of Leuven and is headquartered in Liège, Belgium. CONTACT: Imcyse S.A.
