The relationship between dissociation and antidepressant effects of esketamine nasal spray in patients with treatment-resistant depression
This posthoc analysis further analyzes the results of the TRANSFORM studies using esketamine for patients with treatment-resistant depression. In TRANSFORM-2 the percentage of responders (>50% reduction in MADRS) at day-2 and day-28 did not differ significantly between patients who did versus did not manifest significant dissociation. The mean peak dissociation (CADSS) scores significantly decreased across consecutive doses and fewer patients experienced significant dissociation after the last esketamine dose compared to the first.
