Prescription Drug User Fee Act (PDUFA) Goal Date of October 24, 2014
BEDMINSTER, NJ, USA I December 7, 2014 I NPS Pharmaceuticals, Inc. (NPSP), a global biopharmaceutical company pioneering and delivering therapies that transform the lives of patients with rare diseases worldwide, today announced that the U.S. Food and Drug Administration (FDA) has accepted and filed for review the company’s Biologics License Application (BLA) for Natpara® (recombinant human parathyroid hormone 1-84, (rhPTH[1-84])) for the treatment of hypoparathyroidism. Under the Prescription Drug User Fee Act (PDUFA), the goal date for a decision by the FDA is October 24, 2014.
Natpara is a bioengineered replacement for endogenous parathyroid hormone (PTH) that NPS has developed for the treatment of hypoparathyroidism, a rare endocrine disorder characterized by insufficient levels of parathyroid hormone, a principal regulator of the body’s mineral homeostasis.
“We are pleased that the FDA accepted our BLA filing for Natpara and are looking forward to continuing our collaboration with the Agency as we move towards delivering the first replacement therapy to patients with hypoparathyroidism,” said Roger Garceau, MD, FAAP, executive vice president and chief medical officer of NPS Pharmaceuticals.
The company’s clinical development program for Natpara includes 12 pharmacology studies, five efficacy and safety studies in hypoparathyroidism, and a supporting development program consisting of seven studies in osteoporosis. The pivotal Phase 3 study known as REPLACE, was a randomized, double-blind, placebo controlled study of 134 patients with hypoparathyroidism.
The FDA and European Medicines Agency have granted orphan drug status for Natpara for the treatment of hypoparathyroidism.
About Hypoparathyroidism
PTH plays a central role in a variety of critical physiological functions, including closely modulating serum calcium and phosphate, regulating renal excretion of calcium and phosphate, activating vitamin D, and maintaining normal bone turnover. In patients with hypoparathyroidism, insufficient levels of PTH lead to low serum calcium, high serum phosphate, increased urinary calcium excretion, and decreased urinary phosphorus excretion. PTH deficiency can also disrupt skeletal homeostasis, leading to bone abnormalities. In addition, patients with insufficient levels of PTH are unable to convert native vitamin D into its active state to properly absorb dietary calcium.
Acute symptoms of hypoparathyroidism are largely due to hypocalcemia and include fatigue, muscle spasms and cramps, tingling, tetany, seizures, brain fog/mental lethargy, anxiety, and depression. In the absence of an approved parathyroid replacement therapy, the standard approach focuses on using high doses of calcium and active vitamin D to increase calcium levels in the blood and reduce the severity of hypocalcemic symptoms. However, balancing the administration of supplements is challenging due to calcium fluctuations and the long-term use of high doses of calcium and vitamin D may lead to serious complications, including long-term renal damage. In addition, because serum phosphate levels are elevated when PTH is missing, increasing serum calcium may lead to irreversible calcium-phosphate deposits in the kidneys, arteries or brain. Further, supplements do not correct the abnormal bone metabolism due to PTH deficiency or enable the activation of vitamin D.
About NPS Pharmaceuticals
NPS Pharmaceuticals is a global biopharmaceutical company pioneering and delivering therapies that transform the lives of patients with rare diseases worldwide. The company’s lead product, Gattex® (teduglutide [rDNA origin]) for injection is approved in the US for adult patients with Short Bowel Syndrome (SBS) who are dependent on parenteral support. In the EU, teduglutide (trade name: Revestive®) is approved for the treatment of adult patients with SBS; patients should be stable following a period of intestinal adaptation after surgery. Teduglutide is not approved for the treatment of pediatric SBS patients. The safety and efficacy of teduglutide in this population is currently being evaluated in a global registration trial.
NPS has also developed Natpara® (rhPTH [1-84]) for the treatment of hypoparathyroidism and submitted a Biologics License Application to the US Food and Drug Administration in October 2013.
NPS’ earlier stage pipeline includes NPSP795, a calcilytic compound with potential application in rare disorders involving increased calcium sensing receptor activity, such as autosomal dominant hypocalcemia (ADH). NPS complements its proprietary programs with a royalty-based portfolio of products and product candidates that includes agreements with Amgen, GlaxoSmithKline, Janssen Pharmaceuticals, and Kyowa Hakko Kirin.
