(Nasdaq: APTX), a clinical-stage biopharmaceutical company developing transformative therapies for the treatment of brain and nervous system disorders, today reported financial results for the third quarter of 2021 and provided key business updates across the company’s clinical-stage pipeline of novel NMDA receptor modulators.
