Repurposing existing drugs for treating Leigh syndrome using patient-derived cells

Using iPSC Derived Human Basal Ganglia Neurons From Patients With Leigh Syndrome for Metabolic Studies, Assay Development, and Drug Repurposing.

Observational Charite University, Berlin, Germany · NCT06967831

This study is testing if existing approved drugs can help improve brain cells made from patients with Leigh syndrome to find new treatment options for them.

What this trial studies

This project focuses on using induced pluripotent stem cells (iPSCs) derived from patients with Leigh syndrome to create neural progenitor cells and dopaminergic neurons. The researchers will screen FDA and EMA approved drugs to identify any positive effects on these patient-derived neuronal cells, utilizing various biochemical, optical, and morphological measures. If successful, confirmed positive drug candidates may be used for compassionate off-label treatment in Leigh syndrome patients who lack standard treatment options.

Who should consider this trial

Good fit: Ideal candidates for this study are patients diagnosed with Leigh syndrome who have specific disease-causing mutations.

Not a fit: Patients without a confirmed mutation causing Leigh syndrome or those with bleeding disorders that prevent skin biopsies may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide new treatment options for patients suffering from Leigh syndrome.

How similar studies have performed: While drug repurposing has shown promise in other studies, this specific approach using iPSCs for Leigh syndrome is relatively novel and untested.
