Clinical Trials/Research

The Association has always advocated participation in patient studies and other investigative medical initiatives.  Medical research and patient participation is necessary if medical science is to be advanced, and patient’s quality of life improved.

There are several clinical trials taking place on hypoparathyroidism at this time; too many to list here so we recommend you check out the  website or CenterWatch (see information below) for the complete list of current and upcoming research protocols.

We were asked by some of our Medical Advisors to post info on their resesarch protocols for your consideration and they are listed below.


We are looking for adults who have chronic hypoparathyroidism to participate in a 1-hour telephone interview to discuss their experiences living with hypoparathyroidism in order to understand the symptoms that patients consider important and to give input on two fatigue questionnaires. The interview will be scheduled at a convenient time for the participant.

If you are interested and meet ALL of the following qualifications, we would like to talk to you:

-          An adult (aged 18 years or older) with a diagnosis of chronic hypoparathyroidism  

-          Must reside in the United States

-          Must not have CASR gene mutation or an impaired responsiveness to parathyroid hormone (PTH)

-          Must not have taken in the past or currently be taking Natpara (parathyroid hormone)

-          Must not have taken in the past or currently be taking Forteo (teriparatide)

-          Currently taking oral calcium and vitamin D for the treatment of hypoparathyroidism  

-          Still experiencing symptoms due to chronic hypoparathyroidism, despite ongoing treatment

-          Willing and able to participate in a 1-hour telephone interview

-          Able to read, speak, and understand English

-          Willing and able to provide verbal informed consent for participation in a research study

If you are interested, please contact Nimanee Harris, RTI Health Solutions Project Manager, by phone at (803) 804-1215 or e-mail at Monday - Friday between 9:00 am and 5:00 pm EST.


Has your medicine cabinet started to look like a pharmacy with all the pills and supplements you have for treating your hypoparathyroidism?

We invite you to learn more about the PARALLAX Study, a clinical research study measuring the safety and tolerability of an injectable study drug and its effects on calcium levels in the blood and the amount of calcium passed in the urine, in adults with hypoparathyroidism, when given once a day versus twice a day. The long-term goal of this continuing research is to improve calcium control and potentially to reduce patients’ daily doses and frequency of calcium and vitamin D supplements.

The PARALLAX Study is still actively recruiting. Several sites are now accepting patients and are in the process of adding more in the coming months. The sites that are active on our study website where patients who pass the online pre-screener can be referred are:

  • Columbia University – New York, NY
  • Providence Clinical Research – North Hollywood, CA
  • University of Chicago Medical Center – Chicago, IL
  • Diabetes & Metabolism Associates – Metarie, LA
  • Ohio State University – Columbus, OH
  • Thomas Jefferson University Diabetes Research Center – Philadelphia, PA
  • NOCCR – Knoxville, TN


Columbia Study



The divisions of Pediatric Endocrinology and Pediatric Nephrology at Mass General Hospital for Children (MGHfC) are pleased to announce the Pediatric Bone and Mineral Metabolism Disorders (BAMM) Clinic. The BAMM Clinic is a virtual, multidisciplinary clinic that provides care to infants, children and adolescents with conditions such as low bone density, osteoporosis, vitamin D deficiency, rickets and osteomalacia, hypoparathyroidism and other disorders that affect bone health and mineral metabolism.

Our providers work collaboratively with each child’s primary care provider, appropriate specialists and, most importantly, the child and family to ensure the highest quality of care. For older adolescents, our providers can facilitate a seamless transition from pediatric to adult care to ensure ongoing care for their bone health.

To learn more about the BAMM Clinic at MGHfC, including how to schedule an appointment and members of the care team, please visit  or call the Access and New Appointment Center at 888-644-3248.
