Using Theophylline to Treat Pseudohypoparathyroidism

Phase 2 Study of Theophylline for the Treatment of Psuedohypoparathyroidism

['FUNDING_R01'] · VANDERBILT UNIVERSITY MEDICAL CENTER · NIH-11003699

This study is looking at whether the medication theophylline can help kids with pseudohypoparathyroidism by improving how their hormones work, which might help them grow better and manage their weight.

What this research studies

This research investigates the use of theophylline, a phosphodiesterase inhibitor, to improve hormonal signaling in children with pseudohypoparathyroidism (PHP). PHP is a rare genetic disorder that leads to hormone deficiencies and associated issues like obesity and short stature. The study aims to enhance the function of Gsα-dependent receptors by increasing cyclic adenosine monophosphate (cAMP) levels, which may help reduce body mass index (BMI) and improve overall health outcomes. Participants will be monitored for changes in BMI, growth rates, and hormone resistance during the treatment period.

Who could benefit from this research

Good fit: Ideal candidates for this research are children diagnosed with pseudohypoparathyroidism who are experiencing early-onset obesity and short stature.

Not a fit: Patients without a diagnosis of pseudohypoparathyroidism or those who do not exhibit obesity or growth issues may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a new treatment option for managing obesity and growth issues in children with pseudohypoparathyroidism.

How similar studies have performed: While the use of theophylline in this context is novel, similar approaches targeting hormonal signaling pathways have shown promise in other conditions.
