Takeda Pharmaceutical Company Limited (TSE%3A4502%2FNYSE%3ATAK) (“Takeda”) today announced the final results from the Phase 3 HELP (Hereditary Angioedema Long-term Prophylaxis) Study Open-label Extension (OLE) showing that TAKHZYRO® (lanadelumab-flyo) helped prevent and reduce the frequency of hereditary angioedema (HAE) attacks long term in patients 12 years of age and older who received treatment for a mean (standard deviation) duration of 29.6 (8.2) months.1 Results were consistent with the safety and efficacy of TAKHZYRO in the pivotal trial. The mean (min, max) HAE attack rate was reduced by 87.4% (-100; 852.8) overall versus baseline (N=212) and in a pre-specified exploratory endpoint, nearly 70% (68.9%) of patients treated with TAKHZYRO 300 mg every two weeks experienced an attack-free period of more than 12 months (n=209).1, 2 The data are being presented at the 2020 American College of Allergy, Asthma and Immunology (ACAAI) Virtual Annual Scientific Meeting and will also be published in the November issue of ACAAI’s journal Annals of Allergy, Asthma & Immunology.
