Neurogene Faces Setback with Rett Syndrome Gene Therapy Despite Promising Low Dose Results
Neurogene's NGN-401 gene therapy trial for Rett syndrome initially showed promise, with Phase I/II data indicating significant and durable symptom improvements at low doses[1]. This lower dosage regimen resulted in clinically meaningful enhancements in motor skills, language, and communication for pediatric patients aged 4 to 7, without leading to serious adverse events or seizures[2]. However, the trial experienced a setback when a serious adverse event was reported in a patient under a higher dosage, causing a significant drop in Neurogene's share value. Despite this, analysts have largely interpreted the risk as linked to known AAV vector toxicities, and the low-dose data supports Neurogene's standing as a leader in this field[1][2].
