Better Health, Brighter Future
CAMBRIDGE, Massachusetts, April 11, 2023 – Takeda (TSE:4502/NYSE:TAK) today announced that the U.S. Food and Drug Administration (FDA) has approved a supplemental biologics license application (sBLA) to expand the use of HYQVIA to treat primary immunodeficiency (PI) in children 2-16 years old. HYQVIA is the only subcutaneous immune globulin (ScIG) infusion that can be administered once a month – every three or four weeks – and was first approved in the U.S. in 2014 for the treatment of PI in adults.
PI is an umbrella term to describe a group of more than 400 disorders that affect the body's immune system, increasing susceptibility to infection.1 Children living with PI and their families face distinct challenges as they are more likely to get frequent and serious infections that can impact their school attendance and ability to participate in social activities.2 While immune globulin (IG) infusions can be effective at protecting against infections associated with a PI diagnosis, some therapy options may not be optimal for all children and their families. For example, intravenous route of administration may be difficult for some children and the frequency of some subcutaneous therapies may be challenging for some families’ schedules.2
“Families of children living with primary immunodeficiency may feel overwhelmed by their child’s chronic medical needs. When it comes to treatment, having choices can mean a great deal to families,” said Jorey Berry, president and chief executive officer of the Immune Deficiency Foundation. “The approval of this new PI treatment for children 2 to 16 years old offers an alternative for health care providers and families who might prefer a less frequent treatment option that can be administered subcutaneously at home, after appropriate training, or in an infusion center.”
The FDA approval of HYQVIA for the treatment of PI in pediatric patients was based on evidence from a pivotal, prospective, open-label, non-controlled Phase 3 clinical trial that included 44 PI patients between the ages of 2 and 16. Data were analyzed when all subjects completed 12 months of participation (one year of observation) in the trial. The data showed no clinically meaningful differences in trough Immunoglobulin G (IgG) levels across age groups. During the 12-month trial period, HYQVIA was shown to be efficacious with respect to the occurrence of acute serious bacterial infections (aSBIs), a primary endpoint. The mean aSBI rate per year was 0.04 and was statistically significantly lower (with an upper 1-sided 99% confidence interval of 0.21, p<0.001) than the predefined success rate of less than one aSBI per subject per year, favoring efficacy of HYQVIA treatment in pediatric subjects with PI diseases. The efficacy of HYQVIA in this study was further demonstrated by the overall rate of infections per subject, which is consistent with results obtained in the pivotal clinical study. The mean rate of all infections per subject-year was 3.20, with an upper limit of the 95% confidence interval of 4.05.3 Results from the interim data analysis, where all subjects completed 12 months of participation (one year of observation period) in the study, indicated similar safety profiles to adults.3
"This expanded HYQVIA indication exemplifies our ongoing commitment to providing plasma-derived therapies with proven efficacy. HYQVIA is now available to a broader community impacted by PI, including children and their families with distinct needs, who may prefer flexible treatment options in the management of these disorders," said Brandon Monk, head of Takeda’s U.S. Plasma-Derived Therapies Business Unit.
HYQVIA® is a liquid medicine containing Recombinant Human Hyaluronidase and immunoglobulins (Ig) and approved in the United States to treat adults and children two years of age and older with primary immunodeficiency (PI). It is also approved in the European Union as a replacement therapy in adults, children and adolescents with PI and with secondary immunodeficiency (SID) who suffer from severe or recurrent infections, ineffective antimicrobial treatment, and either proven specific antibody failure (PSAF) or serum IgG level of <4 g/L. HYQVIA is infused under the skin into the fatty subcutaneous tissue. HYQVIA contains immunoglobulins collected from human plasma. Immunoglobulins are antibodies that maintain the body’s immune system. The hyaluronidase part of HYQVIA helps more of the Ig get absorbed into the body. HYQVIA is infused up to once a month (every three or four weeks).

HYQVIA is indicated for the treatment of primary immunodeficiency (PI) in adults and pediatric patients two years of age and older. HYQVIA is for subcutaneous use only. Safety and efficacy of chronic use of Recombinant Human Hyaluronidase in HYQVIA have not been established in conditions other than PI.
WARNING: THROMBOSIS
The most common adverse reactions observed in >5% of patients in the clinical trials were: local adverse reactions including pain, erythema, edema, and pruritus, and systemic adverse reactions including, headache, antibody formation against Recombinant Human Hyaluronidase (rHuPH20), fatigue, nausea, pyrexia, and vomiting.
Passive transfer of antibodies may transiently interfere with the immune responses to live attenuated virus vaccines (e.g., measles, mumps, rubella, and varicella).
Pregnancy: Limited human data are available on the use of HYQVIA during pregnancy. The effects of antibodies to the Recombinant Human Hyaluronidase on the human embryo or fetal development are unknown. It is not known whether HYQVIA can cause fetal harm when administered to a pregnant woman or if it can affect reproductive capacity. HYQVIA should be given to a pregnant woman only if clearly needed.

Primary immunodeficiency is not a single condition; it’s a group of more than 400 rare, chronic disorders that disrupt the body’s immune system from functioning properly.1 These conditions are often inherited; however, some of the disorders are also caused by genetic and environmental factors.1 In the United States, PI affects about 1 in 1,200 people.1 People with PI often face increased susceptibility to infections, repeated infections, and infections that are difficult to treat.1
