Hereditary hypoparathyroidism

This study tests a new drug called encaleret against usual treatments for people with a rare genetic condition called autosomal dominant hypocalcemia type 1 (ADH1), which causes low blood calcium and high urine calcium. About 67 participants will receive either encaleret or stand…

This phase 2 trial tests whether theophylline, a drug used for asthma, can help people with pseudohypoparathyroidism lose weight and improve blood sugar control. The study includes 29 obese participants aged 13 and older. Researchers will measure changes in body mass index and gl…

This study tests whether theophylline, a drug used for asthma, can help children and young adults with pseudohypoparathyroidism—a rare genetic condition causing early obesity, hormone problems, and short stature. Researchers will check for weight loss, better blood sugar control,…

This phase 2 trial tests theophylline, a drug used for asthma, in 34 children aged 2 to 12 with pseudohypoparathyroidism, a genetic condition causing obesity, short stature, and hormone resistance. The study aims to see if theophylline can help with weight loss, slow bone growth …

This study was designed to see if giving calcium right away to trauma patients who need large blood transfusions could help their blood clot better, reduce the need for more transfusions, and improve survival. The trial was withdrawn before enrolling any participants, so no resul…

This study tests whether placing a placental-based allograft called Amnioeffect on the surgical wound improves scar appearance, pain, and swallowing after thyroid or parathyroid surgery. About 334 adults will be enrolled, with half receiving the graft and half getting standard ca…

This study compares two methods of monitoring the nerve that controls the vocal cords during thyroid and parathyroid surgery. The standard method uses a breathing tube with electrodes, while the new method uses tiny needles placed directly into the voice box cartilage. Researcher…

This study follows 600 people with Albright hereditary osteodystrophy, a rare genetic condition affecting bones and hormones. Researchers are looking at how growth hormone treatment affects height and weight in those with a related hormone problem, and also studying thinking and …

This study is for people with autosomal dominant hypocalcemia types 1 or 2, rare genetic conditions that cause low blood calcium. Researchers will collect past and future health data from 95 participants to learn how the disease changes over time. The goal is to better understand…

This study watches 200 people with lung, gut, or hormone diseases over time using special brain scans (PET). It aims to see how these diseases change brain activity and whether those changes can predict tumor return, spread, or survival. No new treatment is tested—just observatio…
