Hansa Biopharma's HNSA-5487 Shows Promising IgG Reduction Results

Hansa Biopharma Reports Positive Results for HNSA-5487

Hansa Biopharma AB is thrilled to share significant findings from the NICE-01 trial of HNSA-5487, a pioneering immunoglobulin G (IgG)-cleaving molecule. This study evaluated the effectiveness of HNSA-5487 with an extended follow-up, revealing remarkable insights into the reduction of IgG levels.

Outstanding IgG Reduction Achieved

During the NICE-01 trial, HNSA-5487 achieved a rapid reduction of IgG levels by more than 95% just hours after administration. A twelve-month follow-up demonstrated that IgG levels normalized within six months post-treatment. This outcome highlights the exceptional efficacy of HNSA-5487, comparable to the results seen with imlifidase, Hansa's previous IgG-cleaving enzyme, all while maintaining a commendable safety profile with no serious adverse effects recorded.

Immunogenicity Profile and Redosing Capabilities

Further analyses indicated that HNSA-5487 exhibited lower anti-drug antibody (ADA) levels prior to treatment, suggesting a markedly lower immunogenicity compared to imlifidase. The strong reduction in ADA responses enhances confidence in HNSA-5487, demonstrating significant potential for safe redosing, which is essential in chronic treatment settings. Nearly all serum samples collected at six and twelve months post-initial dosing confirmed the robust reduction of IgG levels, signifying broad efficacy.

Addressing Chronic Autoimmune Diseases

Søren Tulstrup, President and CEO of Hansa Biopharma, emphasized the connection between rapid IgG reduction and improved therapeutic responses in autoimmune conditions. He noted, "These results reinforce our belief that HNSA-5487 is poised to significantly address the unmet medical needs in autoimmune diseases, including myelin oligodendrocyte glycoprotein antibody disease (MOGAD), neuromyelitis optica (NMO), and myasthenia gravis (MG)."

MOGAD impacts approximately 2 to 3.4 out of every 100,000 individuals worldwide, with a notable prevalence in the pediatric population. In contrast, NMO affects roughly seven out of every 100,000 people, totaling around 22,000 cases in the U.S. Moreover, myasthenia gravis has an estimated global incidence of 150 to 200 per million.

Understanding the Conditions

All the aforementioned conditions are underpinned by wrongfully directed IgG antibodies, and despite their serious nature, current treatment options are limited. HNSA-5487's capability to effectively and promptly reduce IgG levels could alleviate numerous debilitating symptoms associated with these diseases.

Clinical Trial Overview

The NICE-01 trial was a randomized, placebo-controlled study designed to probe the safety, tolerability, pharmacokinetics, and pharmacodynamics of HNSA-5487. It comprised 36 adult participants and has yielded promising results regarding safety and tolerability, establishing a solid foundation for future studies.

Looking Ahead

Hansa Biopharma is set to continue its clinical development of HNSA-5487, focusing primarily on chronic autoimmune diseases where the intervention of IgG is critical. As research evolves, the company aims to explore additional applications of this innovative drug across various autoimmune disorders and conditions involving IgG elevation.
