Treatment for abnormal calcium buildup in a rare genetic condition

Therapy for ectopic calcification in pseudoxanthoma elasticum

['FUNDING_SBIR_1'] · LARIX BIOSCIENCE, LLC · NIH-10763057

This study is testing a new oral treatment for people with pseudoxanthoma elasticum (PXE) that aims to help reduce harmful calcification in the body by using a special form of a substance called inorganic pyrophosphate, which could make a positive difference for those living with this rare condition.

What this research studies

This research focuses on developing a new oral therapy for patients with pseudoxanthoma elasticum (PXE), a rare genetic disorder that causes abnormal calcification in various tissues, including the eyes and blood vessels. The approach involves using a specially formulated version of inorganic pyrophosphate (PPi) that can be taken orally, which aims to restore normal levels of PPi in the body. By increasing PPi levels, the therapy seeks to inhibit the harmful calcification process associated with PXE. The research will include pharmacokinetic and toxicology studies, followed by evaluations in animal models to assess the effectiveness of the treatment.

Who could benefit from this research

Good fit: Ideal candidates for this research are adults diagnosed with pseudoxanthoma elasticum who experience symptoms related to ectopic calcification.

Not a fit: Patients without a diagnosis of pseudoxanthoma elasticum or those with other unrelated conditions may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a novel oral treatment option that significantly reduces ectopic calcification in patients with pseudoxanthoma elasticum.

How similar studies have performed: While the approach of using oral PPi for treatment is innovative, similar strategies targeting ectopic calcification have shown promise in preliminary studies.
