About Hypoparathyroidism

Hypoparathyroidism is a rare disorder in which the body produces insufficient levels of parathyroid hormone, the principal regulator of calcium and phosphorus. When the body has too little parathyroid hormone, blood calcium levels drop and phosphorus levels increase, which can cause physical and neurological symptoms, as well as bone impairments. There is no approved treatment for hypoparathyroidism. It is currently managed with large doses of oral calcium and active vitamin D supplementation to raise the calcium levels in the body and reduce the severity of symptoms. Over time, calcium may build up in the body and result in serious health risks, including calcifications in the kidneys, heart or brain.

The estimated U.S. prevalence of hypoparathyroidism is 80,000 to 100,000.

About Natpara™ (recombinant human parathyroid hormone 1-84 [rDNA origin] injection)

Natpara™ is a bioengineered replica of human parathyroid hormone 1-84 that is being developed as the first hormone replacement therapy for the underlying cause of hypoparathyroidism. NPS reported positive findings from a Phase 3 registration study, known as REPLACE, which met the primary efficacy endpoint with a statistically higher responder rate versus placebo. A responder was defined as a 50 percent or greater reduction in oral calcium supplementation and active vitamin D therapy and a total serum calcium concentration that was maintained compared to baseline.
