4 papers and 2 clinical trials exploring ketamine as a treatment for personality disorders.

CompoundArylcyclohexylamine

Ketamine

A dissociative anesthetic with rapid-acting antidepressant properties, widely used in clinical settings for mood and pain disorders.

Full Ketamine profile
IndicationApproximately 9% of adults globally.

Personality Disorders

Personality disorders, characterised by enduring patterns of behaviour, cognition, and inner experience, present substantial challenges in treatment. Emerging research into psychedelics such as psilocybin, MDMA, and ketamine indicates that they may offer novel therapeutic avenues for addressing these complex conditions.

Real world effectiveness of repeated ketamine infusions for treatment-resistant depression with comorbid borderline personality disorder

In a real‑world observational cohort of 66 patients with treatment‑resistant bipolar I/II depression, four sub‑anaesthetic intravenous ketamine infusions over two weeks produced statistically and clinically significant, progressive reductions in depressive symptoms, suicidality and anxiety (mean QIDS‑SR16 reduction 6.08; p<0.0001). Response and remission rates were 35% and 20% respectively, with generally good tolerability (4.5% treatment‑emergent hypomania, no mania or psychosis).

A pilot randomized controlled trial of ketamine in Borderline Personality Disorder

This randomised controlled trial (n=22) is the first to study ketamine (35mg/70kg) in Borderline (BPD) in a placebo-controlled study. The study didn't report statistically significant differences between the ketamine and midazolam (active placebo) groups, though it did show a positive trend.

Real-world effectiveness of repeated ketamine infusions for treatment resistant depression during the COVID-19 pandemic

This retrospective analysis (n=100) of the effectiveness of ketamine (35mg/70kg) for borderline personality disorder (BPD) in those with treatment-resistant depression (TRD) finds that intravenous ketamine significantly reduces symptoms of depression, borderline personality, suicidality, and anxiety in patients with comorbid BPD and TRD. Both BPD-positive and BPD-negative groups showed significant improvements in the primary outcome measures, with no significant difference between groups.

A Randomized Add-on Trial of an N-methyl-D-aspartate Antagonist in Treatment-Resistant Bipolar Depression

This double-blind, placebo-controlled, randomised study (n=18) with those suffering from bipolar depression (BD; treatment-resistant) found that ketamine (35mg/70kg; 2x 2w apart) produced anti-depressant effects as measured on the MADRS scale. The effects were found immediately (40 minutes) and lasted up to three days.

Ketamine With Dialectical Behavioural Therapy (DBT) for Suicidality in Individuals With Treatment-Resistant Depression and Borderline Personality Disorder (KET-DBT)

This Phase II randomised, quadruple-masked trial (n=120) will study adults aged 18 to 70 years with borderline personality disorder, treatment-resistant major depressive disorder or bipolar disorder, and suicidal ideation, evaluating whether intravenous ketamine plus dialectical behavioural therapy (DBT) reduces suicidal ideation more rapidly and robustly than midazolam plus DBT. The main purpose is to assess change in suicidal ideation severity from baseline to Day 35 using the Modified Scale for Suicidal Ideation (MSSI). All participants will receive DBT for 6 months, starting before the infusions, with weekly individual sessions and the addition of weekly group sessions from Week 5. The experimental arm will receive six intravenous ketamine infusions over 1 month: the first two at 0.5 mg/kg over 40 minutes, infusions 3 and 4 flexibly dosed at 0.5 mg/kg to 0.75 mg/kg, and infusions 5 and 6 flexibly dosed at 0.5 mg/kg to 0.85 mg/kg. The comparator arm will receive six intravenous midazolam infusions over the same period: the first two at 0.02 mg/kg over 40 minutes, infusions 3 and 4 at 0.02 mg/kg to 0.03 mg/kg, and infusions 5 and 6 at 0.2 mg/kg to 0.035 mg/kg. Participants will also complete hospital visits, remote follow-up by call or videocall, and a range of mood, cognitive and behavioural assessments.
