BACKGROUND: Participants who received ketamine at the NIMH were among the first to receive ketamine for depression in controlled clinical trials, providing a unique opportunity to assess long-term outcomes. This analysis evaluated the relationship between participating in a ketamine clinical trial and subsequent ketamine/esketamine use after leaving the research setting.
METHODS: Participants seen within the NIMH Experimental Therapeutics and Pathophysiology Branch from 2002 to 2022 (n = 1000) were contacted for follow-up assessment. Participants reported whether they had used ketamine/esketamine, sought non-prescribed ketamine, attempted suicide, or been psychiatrically hospitalized since discharge. Information regarding their recent depressive symptoms, dissociative symptoms, and hallucinations was also collected.
RESULTS: Of the 203 participants in follow-up assessments (55 % female, average time since leaving NIMH = 9.04 years), 52 (25.6 %) had originally received ketamine at the NIMH, and the rest had participated in non-ketamine studies. Individuals who had received ketamine at the NIMH were more likely to have received ketamine/esketamine post-discharge than those who did not receive ketamine at the NIMH (OR = 0.25, p < .001). Participants who reported using ketamine/esketamine post-discharge reported more depressive symptoms than those who had not (p < .001). Receiving ketamine at the NIMH was not associated with differences in suicide attempts, psychiatric hospitalizations, dissociation, hallucinations, or attempt to obtain non-prescribed ketamine.
LIMITATIONS: Low follow-up study participation rate; varying time since discharge.
CONCLUSIONS: Participants who received ketamine in an NIMH clinical trial were more likely to receive ketamine/esketamine post-discharge, but none reported symptoms indicating abuse. Results underscore the critical need for long-term follow-up of individuals receiving these and other rapid-acting antidepressants.
