Theophylline for Treatment of Pseudohypoparathyroidism

Pseudohypoparathyroidism is a genetic disorder with limited treatment options, characterized by early-onset obesity, short stature, hormone resistance and cognitive impairment. This phase 2 clinical trial will test the efficacy of theophylline, a phosphodiesterase inhibitor, in pseudohypoparathyroidism. We hypothesize that theophylline will cause weight loss, improve glucose tolerance and decrease hormone resistance in children and young adults.

Theophylline Treatment for Pseudohypoparathyroidism - Children 2-12 Years Old

Pseudohypoparathyroidism is a genetic disorder with limited treatment options, characterized by early-onset obesity, short stature and resistance to multiple hormones. This phase 2 clinical trial and open-label extension study will test the efficacy of theophylline, a phosphodiesterase inhibitor, in pseudohypoparathyroidism. We hypothesize that theophylline will cause weight loss, slow the rate of growth plate closure and decrease hormone resistance in children.

Theophylline Treatment for Pseudohypoparathyroidism

Pseudohypoparathyroidism is a genetic disorder with limited treatment options. Patients have early-onset obesity, short stature and increased risk of type 2 diabetes. This phase 2 clinical trial will test the efficacy of theophylline, a phosphodiesterase inhibitor, in pseudohypoparathyroidism. The investigators hypothesize that theophylline will cause weight loss, improve glucose tolerance and slow growth plate closure in children and young adults.

Albright Hereditary Osteodystrophy: Natural History, Growth, and Cognitive/Behavioral Assessments

We, the researchers, are following the natural history of Albright hereditary osteodystrophy. We have found that growth hormone deficiency is very common in patients with pseudohypoparathyroidism type 1A, which falls under the broader condition termed Albright hereditary osteodystrophy. Patients with pseudohypoparathyroidism type 1A typically are short and obese. Some of these patients are not short during childhood, but due to a combination of factors, they end up short as adults. We are evaluating the effect of growth hormone treatment in those patients with pseudohypoparathyroidism type 1A who are found to be growth hormone deficient (under R01 FD002568, IND 67148, which ended); those who are growth hormone sufficient and were found to have a positive clinical response to growth hormone in a prior clinical trial (under R01 FD00FD003409, IND 67148, which ended); or those who meet the criteria of idiopathic short stature or SGA. We are also evaluating neurocognitive and psychosocial functioning in participants with AHO in order to determine the specific impairments that are most common in the condition and to determine the best approach toward management.
