What this phase means
Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Ketamine Hydrochloride, Midazolam Hydrochloride, or Dialectical Behavioral Therapy (DBT). The registry lists allocation as randomized. The goal of this clinical trial is to learn if intravenous (IV) ketamine with Dialectical Behavioural Therapy (DBT) reduces suicidal ideation in individuals with suicidality who have been diagnosed with Borderline Personality Disorder and either Major Depressive Disorder or Bipolar Disorder.
They plan to enroll about 120 people at Toronto. Taking part typically means taking a study drug (or dummy pill), following a program (exercise, therapy, diet, or an app) plus check-ins.
