UniQure has dosed the first patient in its phase 1/2 EPISOD1 trial, evaluating AMT-162, an AAV vector-based gene therapy for SOD1-ALS. AMT-162 uses a miRNA to silence the disease-causing SOD1 gene, delivered via an AAVrh10 vector. The open-label, multicenter study in the US focuses on safety and efficacy, with 4 active sites and plans to activate 7 more by Q1 next year. UniQure also develops AMT-260 for temporal lobe epilepsy, with preclinical data showing potential for a good risk-benefit ratio.
