Ketamine for Methamphetamine Use Disorder (KMD)

March 30, 2026 updated by: Madhukar H. Trivedi, MD, University of Texas Southwestern Medical Center

NIDA CTN-0132 Randomized, Double-Blind, Active Placebo-Controlled Trial of Ketamine for Methamphetamine Use Disorder (KMD)

This study aims to determine whether treatment response with IV ketamine is superior to treatment response with IV midazolam in adults with moderate to severe MUD.

The study design is a 12-week randomized, double-blind, controlled trial comparing intravenous (IV) ketamine against IV midazolam, delivered over six weeks in 120 adults with moderate to severe methamphetamine use disorder (MUD).

Study Overview

Detailed Description

Effective management for methamphetamine use disorder (MUD) remains elusive, despite widespread misuse of this stimulant. Psychological interventions have demonstrated modest benefits, and relapse rates are high. There are currently no Food and Drug Administration (FDA)-approved pharmacotherapies for MUD. This study explores the efficacy, safety, and feasibility for intravenous (IV) ketamine as a treatment for MUD and will help to determine the effect size for a larger, multi-site trial of intravenous (IV) ketamine in MUD.

Participants will receive either IV ketamine (0.50mg/kg) or IV midazolam (0.02mg/kg) over 45 minutes per infusion for a total of eight (8) infusions over six (6) weeks. Medical management sessions with a study clinician will be provided to all participants once weekly (from Weeks 1 through 6).

The use of IV ketamine in this trial is consistent in dose (0.5 mg/kg) and duration of infusion (45-minute-long) to other studies of ketamine for psychiatric disorders (such as major depressive disorder and post-traumatic stress disorder, both of which are often comorbid in individuals with MUD) and substance use disorder. However, IV ketamine has not been directly evaluated as mono-pharmacotherapy in those with MUD yet.

Additionally, participants will be asked to participate in cognitive behavioral therapy (CBT) sessions once weekly (from Weeks 1 through 12) on a non-infusion day.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Ketamine
Participants will receive IV ketamine (0.50mg/kg) dissolved in 0.9% sodium chloride in a total volume of 100mL and administered with an infusion pump at a constant rate over 40 minutes. IV ketamine will be administered 8 times over 6 weeks.
Participants will receive IV ketamine (0.50mg/kg) dissolved in 0.9% sodium chloride in a total volume of 100mL and administered with an infusion pump over 45 minutes. Duration of each infusion may be extended by the Study Clinician supervising study medication infusion if slower infusion rate is better tolerated.
Other Names:
  • Ketelar
Active Comparator: Midazolam
Participants will receive IV midazolam (0.02mg/kg) dissolved in 0.9% sodium chloride in a total volume of 100mL and administered with an infusion pump at a constant rate over 40 minutes. IV midazolam will be administered 8 times over 6 weeks.
