Naltrexone for Nonsuicidal Self-Injury

8. Juni 2026 aktualisiert von: Yong Min Ahn, Seoul National University Hospital

A Randomized, Double-Blinded Clinical Trial to Evaluate the Effectiveness of Naltrexone in Improving Nonsuicidal Self-Injurious Behavior

This randomized, double-blinded, placebo-controlled clinical trial aims to evaluate the efficacy and safety of naltrexone in reducing nonsuicidal self-injurious behavior among individuals with nonsuicidal self-injury. Participants will be randomly assigned to receive either naltrexone plus treatment as usual or placebo plus treatment as usual for 6 weeks.

The primary objective is to determine whether naltrexone reduces the frequency of nonsuicidal self-injurious behavior compared with placebo. Secondary objectives include evaluating changes in clinical severity, suicidal ideation, self-injury-related urges, ecological momentary assessment measures, and safety outcomes.

Detaillierte Beschreibung

Nonsuicidal self-injury is defined as the intentional destruction of one's own body tissue without suicidal intent. It is clinically important because it is associated with emotional dysregulation, impulsivity, psychiatric comorbidity, and increased risk of future suicidal behavior. However, evidence-based pharmacological treatments specifically targeting nonsuicidal self-injurious behavior remain limited.

Naltrexone is an opioid receptor antagonist that has been suggested to reduce repetitive self-injurious behaviors by modulating endogenous opioid-related reinforcement mechanisms. This study will investigate whether naltrexone is effective in reducing nonsuicidal self-injurious behavior in a randomized, double-blinded, placebo-controlled design.

A total of 150 participants will be enrolled across multiple study sites. Eligible participants will be randomly assigned in a 1:1 ratio to either the naltrexone group or the placebo group. The intervention period will last 6 weeks, with clinical evaluations conducted at baseline and every 2 weeks thereafter. Smartphone-based ecological momentary assessment will also be used to monitor self-injurious urges, mood states, and related behavioral variables during the study period.

Safety will be assessed throughout the study through adverse event monitoring, assessment of suicidal ideation and behavior, laboratory testing, urine testing, and electrocardiography according to the study schedule.

    2. Current opioid use, opioid dependence, or use of opioid-containing medications.
    3. Current use of opioid antagonists or medications that may interact with naltrexone, including methadone or buprenorphine.
    4. Use of naltrexone within 1 week before screening.
