Human normal immunoglobulin(Takeda)

OSAKA, Japan & CAMBRIDGE, Mass.--( BUSINESS WIRE )--Takeda (TSE:4502/NYSE:TAK) today announced that the Japanese Ministry of Health, Labour and Welfare has approved the use of HYQVIA ® [Immune Globulin Infusion 10% (Human) with Recombinant Human Hyaluronidase] in patients with agammaglobulinemia or hypogammaglobulinemia 1 , disorders characterized by very low or absent levels of antibodies and an increased risk of serious recurring infection caused by primary immunodeficiency (PID) or secondary immunodeficiency (SID) 2 . The approval marks availability of the first and only facilitated subcutaneous immunoglobulin (fSCIG) therapy as a treatment option for appropriate patients in Japan. HYQVIA is the first plasma-derived therapy for subcutaneous injection in Japan that consists of a combination of one vial of Immunoglobulin 10% and one vial of Recombinant Human Hyaluronidase PH20 (rHuPH20). The administration of rHuPH20 increases the dispersion and absorption of immunoglobulin (IG) in the subcutaneous tissue, allowing larger volumes to be infused in the infusion site. This allows for less frequent dosing compared to other subcutaneous IG products, while avoiding the need for venous access. The ability to infuse a larger infusion volume is expected to increase administration flexibility for patients with agammaglobulinemia or hypogammaglobulinemia by decreasing the dosing frequency to once every 3 or 4 weeks, as compared to weekly or bi-weekly with conventional SCIG treatments. The approval is based on data from two pivotal Phase 3, open-label, non-controlled studies evaluating the efficacy, safety, tolerability and pharmacokinetics in Japanese subjects with PID ( NCT05150340 , NCT05513586 ). In these studies, the efficacy and safety profile of HYQVIA in 16 patients aged 2 years or older in Japan were evaluated based on the results of the clinical trials. The Geo Mean of IgG trough level at the last 3 visits was 9.494g/L and was maintained at level comparable to treatment with intravenous or subcutaneous immunoglobulin (Geo Mean of IgG trough level 9.624g/L). The major adverse reactions were pyrexia 5 patients (31.3%) and infusion site erythema, injection site erythema, infusion site swelling, infusion site pain, and headache (12.5%) 1 . Data from two Phase 3 clinical trials conducted in patients with PID in North America ( NCT00814320 , NCT01175213 ) was also included in the submission. “ We are delighted that HYQVIA, approved in more than 40 countries worldwide, has now been approved in Japan,” said Naoyoshi Hirota, Regional Head of Research & Development for Takeda’s Plasma-Derived Therapies Business Unit in Japan. “ The subcutaneous IG therapies currently available in Japan for patients with agammaglobulinemia or hypogammaglobulinemia require infusion once every week or every 2 weeks. We are proud to offer Japanese patients the first and only facilitated subcutaneous treatment option that offers a reduced dosing frequency of every 3 or 4 weeks.” “ There is a high unmet need for plasma-derived therapies (PDTs) in patients in Japan, which is anticipated to increase as education and timely diagnosis rates continue to improve,” said Kristina Allikmets, head of research & development for Takeda’s Plasma-Derived Therapies Business Unit. “ The approval of HYQVIA, the first and only facilitated SCIG treatment, is further evidence of Takeda’s commitment to add to the standard of care for patients in Japan. We look forward to continuing to bring new therapeutic options that support and enhance the experience of patients in our home country throughout the next decade.” With this approval, Takeda is now able to offer a range of SCIG therapies to patients based on their individual administrative needs, reflecting the company’s commitment to offer patients in Japan a broader choice of treatment options. It also follows the announcement of a significant investment to build a new manufacturing facility for plasma-derived therapies (PDTs) in Osaka, Japan. HYQVIA is also currently under review in Japan for additional indications. About Agammaglobulinemia or Hypogammaglobulinemia Agammaglobulinemia is an inherited disorder caused by a gene defect that blocks the growth of normal, mature immune cells called B lymphocytes 3 . Hypogammaglobulinemia is a condition in which patients have low levels of antibodies due either to inherited genetic conditions (PID) or secondary effects (SID) – like chemotherapy, certain comorbid disorders, or immunosuppressants 2 . Individuals with any form of antibody deficiency frequently experience recurring and/or severe infections, and immunoglobulin replacement therapy can increase the level of antibodies in the body. About Primary Immunodeficiency and Secondary Immunodeficiency Primary immunodeficiency describes a heterogeneous group of more than 480 rare genetic diseases wherein part of the immune system is missing or not functioning properly 4 . Secondary immunodeficiency is defined as an acquired impairment of the immune response resulting from an underlying condition or factors extrinsic to the immune system. SID may occur as a consequence of malnutrition, metabolic disorders, use of immunosuppressive medications, chronic infections, malignancies, or severe trauma 5 . Due to their impaired immune system, patients with PID and SID may be more susceptible to infection, and it may take longer to recover from it. In patients with antibody deficiency and increased susceptibility and/or persistent infections, substitution with functional antibodies (immunoglobulin replacement therapy) is the standard of care to support the immune system's functioning 5 . About HYQVIA ® HYQVIA is the combination product for subcutaneous injection containing one each vial of Subcutaneous Immunoglobulin 10% (SCIG10%) and Recombinant Human Hyaluronidase PH20 (rHuPH20). As of May 2024, HYQVIA has been approved in more than 40 countries worldwide.

SHANGHAI & CAMBRIDGE, Mass.--( BUSINESS WIRE )--Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688) and argenx (Euronext & Nasdaq: ARGX) today announced that China’s National Medical Products Administration (NMPA) approved the supplemental Biologics License Application (sBLA) for VYVGART Hytrulo 1,000mg (5.6ml)/vial [Efgartigimod Alfa Injection (Subcutaneous Injection)] for the treatment of adult patients with chronic inflammatory demyelinating polyneuropathy (CIDP). VYVGART Hytrulo is approved for CIDP as a once weekly 30-to-90 second subcutaneous injection. It is the first and only therapy approved in China for the treatment of CIDP, a debilitating, often progressive, immune-mediated neuromuscular disorder of the peripheral nervous system. “We are pleased to receive NMPA approval for VYVGART Hytrulo, marking a groundbreaking milestone for CIDP patients in China,” said Rafael G. Amado, M.D., President, Head of Global Research and Development at Zai Lab. “This approval brings a much-needed treatment option to patients who have been suffering from CIDP for far too long. We appreciate the NMPA for their thorough assessment and recognition of the therapy’s differentiated profile and the large unmet patient medical need in China. We will continue to work with argenx to explore the potential in other Immunoglobulin G (IgG)-mediated autoimmune indications.” “VYVGART Hytrulo is a precision therapy for patients living with CIDP, many of whom have been waiting for a new treatment innovation,” said Tim Van Hauwermeiren, Chief Executive Officer of argenx. “We are grateful to our partners at Zai Lab for collaborating with argenx to reach CIDP patients in China, and to the NMPA for approving VYVGART Hytrulo for CIDP. Zai has a strong record of impeccable execution and a shared value of doing all that we can, together, for patients in need. We look forward to continuing our partnership with Zai as argenx continues to reach more patients in one of the world’s fastest growing markets.” “CIDP is a serious and debilitating disease with approximately 50,000 diagnosed patients in China 1 , with only a small fraction of patients able to achieve remission on corticosteroids and plasma-derived therapies, the current standard of care.” said Prof. Ting Chang, M.D., Deputy Chief Physician and Associate Professor, Department of Neurology, Tangdu Hospital. “In addition, existing treatment options are problematic and challenging for some patients. VYVGART Hytrulo provides a new, safe and effective treatment option that can meaningfully improve and stabilize disease symptoms and potentially lessen the burden of treatment for these patients. This is an important advancement for the patient community, and we are grateful to Zai Lab for their work supporting patients who have been devastated by this disease for so long.” The NMPA approval is supported by the positive results from the ADHERE (NCT04281472) study, a multicenter, randomized, double-blind, placebo-controlled trial evaluating VYVGART Hytrulo for the treatment of CIDP. The ADHERE study included an open-label period to identify responders who then entered a randomized-withdrawal, double-blinded period. Zai Lab enrolled patients into the ADHERE trial in Greater China and treatment response in these participants was consistent with global study outcomes. Subgroup analysis of Chinese participants demonstrated a 69% reduction in the risk of relapse with VYVGART Hytrulo compared to placebo. In addition, 78% of Chinese participants treated in the open-label period of the study demonstrated evidence of clinical improvement, further confirming the role IgG autoantibodies play in the underlying biology of CIDP. The favorable safety and tolerability profile of VYVGART Hytrulo dosed weekly in the Chinese patient cohort was consistent with what was shown in global trial participants. In May 2024, Zai Lab announced that the Centre for Drug Evaluation (CDE) accepted the sBLA with priority review designation for VYVGART Hytrulo for CIDP in China. The CDE granted the Breakthrough Therapy Designation for the treatment of patients with CIDP in September 2023. About VYVGART Hytrulo VYVGART Hytrulo is a subcutaneous product that consists of efgartigimod alfa, a human IgG1 antibody fragment, and recombinant human hyaluronidase PH20 (rHuPH20), Halozyme’s ENHANZE ® drug delivery technology to facilitate subcutaneous delivery of biologics. The product is a single subcutaneous injection (1,000 mg fixed dose) delivered over 30-to-90 seconds and given weekly. VYVGART Hytrulo can be administered by a healthcare professional or at home by the patient or caregiver after adequate training in the subcutaneous injection technique. It is approved in the United States (marketed as VYVGART ® Hytrulo for generalized myasthenia gravis (gMG) and CIDP), EU (marketed as VYVGART ® SC for gMG), Japan (marketed as VYVDURA ® for gMG) and China (marketed as VYVGART Hytrulo ® for gMG and CIDP). Zai Lab has an exclusive license agreement with argenx to develop and commercialize efgartigimod in mainland China, Hong Kong, Macau, and Taiwan (collectively, Greater China). About CIDP in China There are an estimated 50,000 patients diagnosed with CIDP in mainland China. 1 Current treatment options are primarily corticosteroids and intravenous immunoglobulin (IVIg), with plasma exchange (PLEX) generally reserved for refractory patients. There is limited access to PLEX or IVIg in many parts of the world, including China. Because most patients require treatment for an extended period, there remains a significant unmet need for alternative treatment options that are effective, well-tolerated, and convenient for patients with CIDP in China. 1 Chronic inflammatory demyelinating polyneuropathy and diabetes, 2020.
