Several studies have investigated replacement therapy with recombinant human parathyroid hormone [rhPTH(1-84)] for patients affected by chronic hypoparathyroidism who are not adequately controlled with standard treatment. In 2015, the Food and Drug Administration (FDA) in the USA approved rhPTH(1-84), named Natpara®, for the pharmacological management of hypoparathyroidism. In Europe, in February 2017, the European Medicines Agency (EMA) recommended granting a conditional marketing authorization in the European Union for rhPTH(1-84). Here we review the studies conducted with rhPTH(1-84) and PTH(1-34) in patients with chronic hypoparathyroidism. The research done in this field has shown that replacement treatment with rhPTH(1-84) is an important therapeutic option for subjects with chronic hypoparathyroidism who are not well controlled with conventional treatment. However, further long-term investigations are needed.
