Recruiting PHASE2 Methamphetamine Abuse

New treatment option for Methamphetamine Abuse

Official title Feasibility of Long-term, High-dose Stimulant for Methamphetamine Use Disorder

ClinicalTrials.gov ID: NCT06788587

What this study is testing

What is LDX-01 plus TAU?

LDX-01 plus TAU is an investigational medicine, given as an once-weekly, being studied as a potential treatment for methamphetamine abuse.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
Methamphetamine use disorder (MUD) is becoming an increasing public health concern in Canada. While the evidence on the efficacy and safety of prescription psychostimulants for the treatment of MUD is promising, the knowledge on the maintenance therapy using stimulant agonist therapy is scarce and needs further investigation, especially in terms of long-term retention in treatment.
  • Phase 2: a mid-size study of how well it works
  • You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
