Abstract
Subcutaneous asfotase alfa (Strensiq™), a first-in-class bone-targeted human recombinant tissue-nonspecific alkaline phosphatase (TNSALP) replacement therapy, is approved in the USA for the treatment of patients with perinatal/infantile- or juvenile-onset hypophosphatasia (HPP). In clinical trials, asfotase alfa was an effective and generally well tolerated treatment for perinatal/infantile- and juvenile onset-HPP through at least 3 and 5 years' treatment, respectively. Relative to untreated age-matched, juvenile-onset-HPP historical control cohorts, survival and ventilation-free survival were significantly prolonged in asfotase alfa-treated patients, consequent to preceding improvements in bone mineralization.
