CAMBRIDGE, Massachusetts , February 9, 2022 (press release) –

Takeda (TSE:4502/NYSE:TAK) today announced the U.S. Food and Drug Administration (FDA) approval of the TAKHZYRO® (lanadelumab-flyo) injection single-dose prefilled syringe (PFS) to prevent attacks of hereditary angioedema (HAE) in adult and pediatric patients 12 years of age and older. The PFS is ready to use and requires fewer preparation steps than the current TAKHZYRO vial injection, while also reducing supplies and waste.1

“Today’s announcement is an important innovation for TAKHZYRO, offering people living with HAE and their caregivers an enhanced treatment administration experience with proven sustained reduction of attacks,” said Cheryl Schwartz, Senior Vice President, Rare Disease Business Unit at Takeda Pharmaceutical Company Limited. “This product delivery enhancement is intended to improve the overall patient experience and reflects Takeda’s continued commitment to the HAE community; we look forward to introducing this new option to patients later this year.”

TAKHZYRO is supported by a robust clinical development program, which includes one of the largest prevention studies in HAE with the longest active treatment duration.1,2 TAKHZYRO is currently approved and available in more than 30 countries around the world.

It is often under-recognized, under-diagnosed and under-treated.3,6
