AADC deficiency is an inherited disorder that affects how signals are passed between certain cells in the nervous system. Signs and symptoms of AADC deficiency generally appear in the first year of life.
The CHMP opinion is based on clinical studies conducted in Taiwan. In addition, data from the compassionate use treatment of patients in Europe were included in the application.
Price Action: PTCT shares are down 1.69% at $31.95 during the market session on the last check Friday.
