Ketamine Treatment of Youth Suicide Attempters
Sponsor: Tatiana Falcone, MD
Summary
Ketamine, an NMDA antagonist, has been shown to have rapid anti- suicidal effects. However, its safety and efficacy and special populations has not been investigated and documented. Several reports in adults suggest rapid decrease of suicidal ideation. In the last decade there is an alarming increase of the number of suicide attempts in patients ages 14-30. Suicide is the second leading cause of death in this population. Patients with previous history of suicide attempt, are even in a higher risk category. The present study focus in this high risk group of suicide attempters. This will be a randomized controlled trial enrolling 60 youth between the ages 14-30 after a suicide attempt; patients will be randomized to receive Ketamine 0.5 mg/kg over 40 minutes or normal saline. Patients will receive all Ketamine or placebo infusions while admitted in the Inpatient Psychiatry Service. Patients will receive up to 6 ketamine or placebo infusions until, for 3 consecutive sessions, they have a clinician rated Scale for Suicidal Ideation (SSI) score of\<4, and \>50% decrease from baseline, and clinical assessment of patient not being suicidal, or they have been discharged from the inpatient unit. Patients will participate in weekly sessions of Collaborative Assessment for the management of Suicidality (CAMS), from the first week of the study while admitted to the hospital and will continue it on a weekly basis post-discharge until the patient has three consecutive outpatient CAMS sessions with an overall risk \< 2 (# 6 on the SSF Core Assessment) along with a positive response regarding their thoughts/feelings and clinician indicating behavioral stability (suicidal behavior).

Interventions
Ketamine Hydrochloride
Ketamine hydrochloride will be given as an intravenous infusion using a standard regimen given in most studies conducted: 0.5 mg/kg over 40 minutes. Ketamine infusions will be given every other day until either the subject reports clinician rated Scale for Suicidal Ideation (SSI) score of\<4, and \>50% decrease from baseline, and clinical assessment of patient not being suicidal for three consecutive pre-infusion ratings, or a maximum of six infusions have been given over the course of 2 weeks, or they have been discharged from the inpatient unit.
Saline
Subjects randomized to placebo will be administered a saline (0.9% sodium chloride) drip for 40 minutes. Saline placebo infusions will be given every other day until either the subject reports clinician rated Scale for Suicidal Ideation (SSI) score of\<4, and \>50% decrease from baseline, and clinical assessment of patient not being suicidal for three consecutive pre-infusion ratings, or a maximum of six infusions have been given over the course of 2 weeks, or they have been discharged from the inpatient unit.
CAMS Therapy
CAMS weekly sessions will also be started immediately as an inpatient at the start of the study while receiving ketamine or saline. CAMS will be continued weekly after the patient is discharged and followed up as an outpatient. Weekly CAMS sessions will be terminated after the subject, as an outpatient, has three consecutive outpatient CAMS sessions with an overall risk \< 2 (# 6 on the SSF Core Assessment) along with a positive response regarding their thoughts/feelings and clinician indicating behavioral stability (suicidal behavior).
