Clinical Trial of the Dual Vector Base Editor for the Treatment of the CHD3-R1025W Mutation

The base editor is delivered using a dual vector adeno-associated virus (AAV) system and introduced into the child via intrathecal injection to correct the mutated CHD3 gene. The vital signs of the child will be closely monitored during treatment to assess possible acute adverse effects. The child will be followed up regularly after treatment to monitor the success of gene editing and the neurodevelopmental improvement of the child. Possible long-term adverse events will be closely monitored to assess the safety of the treatment.
