Takeda gets Japenese nod for Hyqvia 10% SC injection set for Agammaglobulinemia
Osaka: Takeda has 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, 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).
The approval marks availability of a facilitated subcutaneous immunoglobulin (fSCIG) therapy as a treatment option for appropriate patients in Japan.
HYQVIA is a 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. 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).Data from two Phase 3 clinical trials conducted in patients with PID in North America 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.”
HYQVIA is also currently under review in Japan for additional indications.
