About this trial
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).

Treatments tested in this trial
Ketamine Hydrochloride
DrugParticipants 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.
Midazolam Hydrochloride
DrugParticipants 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 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.
Treatment groups
Trial outcomes
Primary outcomes
Treatment Response
Defined as having at least three methamphetamine-negative urine samples out of four samples obtained during Weeks 3 and 4.
Secondary outcomes
Non-serious adverse outcomes associated with IV ketamine treatment for methamphetamine use
Defined by non-serious adverse events (associated with the IV ketamine treatment) reported during the study intervention phase (weeks 1 to 6). Participants will be assessed for adverse events at each study visit.
Adherence to treatment
Defined by completion of at least five out of eight IV ketamine or IV midazolam infusions.
Total abstinence
Defined as four out of four methamphetamine-negative urine samples obtained during Weeks 3 and 4 (since missing urine drug screens will be counted as positive).
Abstinence from methamphetamine use
Defined by the self-reported days of methamphetamine use as reported on the Timeline Followback (TLFB) from Week 1 to Week 4, Week 5 to Week 6, and Week 7 to Week 12.
