Shire to Highlight Advancements in Chronic Hypoparathyroidism Research at the Endocrine Society’s 2018 Annual Meeting

Posted on: 13 Mar 18


-       Clinical and real-world insights on recombinant human parathyroid hormone (1-84) (rhPTH[1-84]) and the management of chronic hypoparathyroidism to be presented

-       Hypoparathyroidism is a rare endocrine disease that can have a significant impact on patients

-       New data highlight Shire’s commitment to making a meaningful difference for patients living with this rare disease.


Dublin, Ireland – March 12, 2018 – Shire plc (LSE: SHP, NASDAQ: SHPG), the global biotechnology leader in rare diseases, today announced that it will share new data on recombinant human parathyroid hormone (1-84) (rhPTH[1-84]) and on the management of chronic hypoparathyroidism at the upcoming Endocrine Society’s 100th Annual Meeting and Exposition (ENDO), on March 17–20 in Chicago, Illinois.


Hypoparathyroidism is a rare endocrine disease that occurs when inadequate levels of parathyroid hormone (PTH) are secreted by the parathyroid glands, resulting in a mineral imbalance in the body expressed by a low concentration of calcium (hypocalcemia) and a high concentration of phosphate (hyperphosphatemia) in the blood.1 It is estimated that the total number of people with hypoparathyroidism in the United States is about 77,000.2 Hypoparathyroidism can have a significant impact on patients through physical and cognitive symptoms.3,4


“Patients with hypoparathyroidism can experience multiple symptoms and a reduced health-related quality of life,” said Howard Mayer M.D., Senior Vice President and Chief Medical Officer, Shire. “With our continuing program of clinical and real-world insights on the chronic form of this rare endocrine disease, we are committed to expand the understanding of the long-term burden of the disease for patients. At ENDO we will be sharing new data in chronic hypoparathyroidism to help healthcare professionals improve the management of their patients.”


The latest data will reveal clinical and real-world insights into chronic hypoparathyroidism, including effects on renal parameters,5 impact on health-related quality-of-life scores,6 and an analysis of the latest five-year results from the ongoing RACE study.7 These data demonstrate Shire’s long-term commitment to advancing understanding of this rare condition in order to further meet the needs of people living with chronic hypoparathyroidism.


Shire will have two poster presentations and one oral presentation on chronic hypoparathyroidism and will be hosting an exhibit at Booth #4220.

Oral presentation #OR20-3


All abstracts are available on the ENDO website at!/4482.


About Hypoparathyroidism

Chronic hypoparathyroidism is diagnosed in patients with a low concentration of calcium in the blood and inappropriately low PTH levels; for postsurgical hypoparathyroidism, the features of hypoparathyroidism must persist for at least 6 months after surgery to be considered chronic.3,8  


About NATPARA® (parathyroid hormone) for Injection

NATPARA, available as 25, 50, 75, and 100 mcg per dose strength, is a parathyroid hormone indicated as an adjunct to calcium and vitamin D to control hypocalcemia in patients with hypoparathyroidism. Because of the potential risk of osteosarcoma, NATPARA is recommended only for patients who cannot be well-controlled on calcium supplements and active forms of vitamin D alone. NATPARA was not studied in patients with hypoparathyroidism caused by calcium-sensing receptor mutations. NATPARA was not studied in patients with acute post-surgical hypoparathyroidism.


Select Important Safety Information

WARNING: POTENTIAL RISK OF OSTEOSARCOMA: In male and female rats, parathyroid hormone caused an increase in the incidence of osteosarcoma (a malignant bone tumor) that was dependent on dose and treatment duration. A risk to humans could not be excluded. Because of the potential risk of osteosarcoma, prescribe NATPARA only to patients who cannot be well-controlled on calcium and active forms of vitamin D and for whom the potential benefits are considered to outweigh the potential risk.


Avoid use of NATPARA in patients who are at increased baseline risk for osteosarcoma (including those with Paget’s disease of bone or unexplained elevations of alkaline phosphatase, pediatric and young adult patients with open epiphyses, patients with hereditary disorders predisposing to osteosarcoma or patients with a history of prior external beam or implant radiation therapy involving the skeleton). NATPARA is available only through a restricted program called the NATPARA REMS Program.


NATPARA Warnings and Precautions include: Severe Hypercalcemia -- monitor serum calcium when starting or adjusting NATPARA dose and when making changes to coadministered drugs known to raise serum calcium. Severe Hypocalcemia can occur with interruption or discontinuation of NATPARA treatment -- Monitor serum calcium and replace calcium and vitamin D. Hypercalcemia increases the risk of digoxin toxicity -- in patients using NATPARA concomitantly with digoxin, monitor serum calcium more frequently and increase monitoring when initiating or adjusting NATPARA dose.


The most common adverse reactions associated with NATPARA and occurring in greater than 10% of individuals were: paresthesia, hypocalcemia, headache, hypercalcemia, nausea, hypoaesthesia, diarrhea, vomiting, arthralgia, hypercalciuria and pain in extremity.
