The once-monthly injectable treatment promises to reduce the risk of debilitating swelling attacks.
Tokyo, Japan – In a significant step forward for the treatment of a rare and perhaps life-threatening genetic condition, Japan’s Ministry of Health, Labor and Welfare (MHLW) has approved Andembry (garadacimab) for hereditary angioedema (HAE). Developed by CSL behring, this innovative therapy aims to reduce the frequency and severity of swelling attacks in individuals living with HAE, offering a new avenue for long-term prevention and improved quality of life.
Hereditary angioedema is characterized by recurrent episodes of severe swelling, frequently affecting the face, throat, limbs, and abdomen. These attacks can be unpredictable and debilitating, substantially impacting a patient’s quality of life. The approval of Andembry offers a new avenue for long-term prevention,providing patients with a more convenient and effective way to manage their condition. The condition stems from a genetic defect that leads to an overproduction of a protein called bradykinin, which causes fluid to leak from blood vessels into surrounding tissues, resulting in swelling.
Andembry stands out as the frist long-term preventive treatment in Japan to be available in a prefilled pen, administered once a month via subcutaneous injection. This user-kind approach aims to improve patient adherence and overall treatment outcomes. The convenience of a monthly injection,self-administered under the skin,represents an significant betterment over previous treatment options,which frequently enough required more frequent or complex administration. This ease of use is expected to significantly improve patient compliance and reduce the burden of managing this chronic condition.
Bill Mezzanotte, MD, executive vice president and head of research and advancement at CSL, emphasized the importance of this approval, stating, Andembry represents a major advancement in the management of hereditary angioedema, offering people living with this life-threatening condition long-term disease control through a patient-centric and convenient administration method.
The approval in Japan follows closely on the heels of similar decisions in other regions. andembry has recently been approved for HAE treatment in the U.K., Australia, and the European Union.Moreover, its approval is currently under consideration in the U.S., signaling a growing global recognition of its potential benefits for HAE patients. This widespread interest underscores the unmet need for effective and convenient HAE treatments worldwide.
Mezzanotte further added, This milestone is the result of decades of dedication, and we extend our gratitude to the colleagues, physicians, and patients who made this possible for HAE patients and CSL.
The development of Andembry represents a significant investment in research and development, reflecting CSL Behring‘s commitment to addressing the needs of patients with rare and serious diseases.
How andembry Works: Targeting the Root Cause of HAE Attacks
HAE is driven by an overproduction of bradykinin,a signaling molecule that triggers swelling attacks. Andembry, an antibody-based therapy, works by inhibiting factor XII (FXII), a protein involved in the chain of events leading to bradykinin production. By blocking FXII, Andembry effectively reduces bradykinin levels, thereby decreasing the risk of swelling attacks. This targeted approach addresses the underlying cause of HAE, rather than simply managing the symptoms.
Rose Fida, PhD, executive director and regional lead of CSL research and development in japan and China, described Andembry as a breakthrough therapy as the first and only treatment targeting activated Factor XII, the key initiator of HAE attacks.
She further noted, With its novel mechanism, once-monthly subcutaneous dosing and easy-to-use prefilled pen, Andembry is set to transform the way HAE is managed in Japan.
This novel mechanism of action sets Andembry apart from other HAE treatments, offering a new and potentially more effective approach to preventing swelling attacks.
Clinical Trial Results: Demonstrating Efficacy and Safety
The applications for Andembry’s approval were primarily based on data from the VANGUARD (NCT04656418) Phase 3 clinical trial. This trial involved 64 participants with HAE, aged 12 and older, who were randomly assigned to receive monthly injections of either Andembry or a placebo for approximately six months.The VANGUARD trial was a randomized, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of Andembry in preventing HAE attacks.
The results of the VANGUARD trial demonstrated a significant reduction in the rate of swelling attacks among patients treated with Andembry. Specifically, the rate of attacks was reduced by more than 85% compared to those receiving the placebo. Notably, approximately two-thirds of the patients in the Andembry group experienced complete freedom from swelling attacks throughout the duration of the trial. These findings provide strong evidence of Andembry’s effectiveness in preventing HAE attacks.
Following the completion of the VANGUARD trial, most participants enrolled in an open-label extension study (NCT04739059), where all participants are receiving Andembry and are being monitored for long-term safety and efficacy. Available data from this ongoing extension study continue to support the treatment’s ability to prevent swelling attacks over an extended period. This long-term data is crucial for understanding the durability of Andembry’s effects and its potential impact on the long-term management of HAE.
Further research is underway to evaluate the safety and efficacy of Andembry in younger patients.A separate Phase 3 trial (NCT05819775) is currently testing Andembry in children with HAE aged 2-11, with an expected completion date in late 2026. This study will provide valuable information about the use of Andembry in pediatric patients,potentially expanding the treatment options available to this vulnerable population.
