Takeda Pharmaceutical Company Limited (TSE%3A+4502/NYSE:TAK) (“Takeda”) today announced the publication of the final results from the Phase 3 HELP (Hereditary Angioedema Long-term Prophylaxis) Study™ Open-label Extension (OLE) designed to evaluate the long-term safety (primary endpoint) and efficacy of TAKHZYRO® (lanadelumab) 300mg every two weeks for up to 2.5 years. The study results show that preventative treatment with TAKHZYRO markedly reduced the frequency of hereditary angioedema (HAE) attacks in patients 12 years of age and older who received treatment for a mean duration of almost 2.5 years (29.6 months; 8.2 standard deviation).1 The data were published online this month in the journal Allergy.
