FA mouse model with 800 GAA repeats better at capturing disease

A recent mouse model of Friedreich’s ataxia (FA), called YG8-800, better mimics the disease’s symptoms and mechanisms in people than earlier models, making it a useful tool for testing treatments aiming to slow or stop disease progression, a study reports. Specially, YG8-800 mice carry a mutation that causes repeats…

FA cell therapy PPL-001 granted orphan drug status by FDA

The U.S. Food and Drug Administration (FDA) has granted orphan drug status to PPL-001, Papillon Therapeutics‘ cell therapy for Friedreich’s ataxia (FA). According to Papillon, PPL-001 uses a “unique multi-systemic approach to treat patients” with FA. The cell-based therapy “offers the potential to modify and reverse disease progression,”…

Eye movement abnormalities may help detect, track FA progression

People with Friedreich’s ataxia often show abnormalities in their eye movements and looking for characteristic changes there may help diagnose the disease and track its progression, a review study finds. “Quantitative oculomotor [eye movement] testing in [Friedreich’s ataxia] may facilitate early diagnosis and provide value in monitoring disease…
