Brief summary

This is a pilot randomized cross-over trial to examine the effects of tirzepatide on cue-reactivity among individuals with cannabis use disorder.

Detailed description

This is a pilot randomized cross-over trial to examine the effects of tirzepatide on cue-reactivity among individuals with cannabis use disorder. Eligible participants will be scheduled in random order to receive either tirzepatide or placebo injection in double-blind fashion and cross-over design. Outcomes will be assessed at the following study visit. Washout period of at least 4 weeks will be required between tirzepatide or placebo injections. Primary outcome of interest is cue-induced craving to cannabis-related visual cues.

Design outcomes

Primary

MeasureTime frameDescription
Cue-Induced Craving5 weeksCraving scores will be assessed using a cue-reactivity paradigm in which participants are exposed to cannabis\]-related cues. Scores range from 0 to 30, with higher scores indicating greater craving intensity.

Secondary

MeasureTime frameDescription
Cravings5 weeksCannabis craving scale using the 12-item questionnaire, each item scored on a 1-7 sale. Higher scores (either average or summed) indicates stronger cravings.
Abstinence5 weeksPercent days abstinent from cannabis
Weight5 weeksWeight
Blood sugar5 weeksBlood glucose
Serious adverse event5 weeksIncidence of serious adverse events
Depression severity as measured by the Patient Health Questionnaire-8 (PHQ-8)5 weeksDepression severity as measured by the Patient Health Questionnaire-8 (PHQ-8). The PHQ-8 assesses depression severity over the past two weeks. Total scores range from 0 to 24, with higher scores indicating greater depression severity (worse outcome). Score interpretation: 0-4 (none), 5-9 (mild), 10-14 (moderate), 15-19 (moderately severe), 20-24 (severe depression).
Anxiety severity as measured by the Generalized Anxiety Disorder-7 scale (GAD-7)5 weeksThe GAD-7 assesses anxiety symptom severity over the past two weeks. Total scores range from 0 to 21, with higher scores indicating greater anxiety severity (worse outcome). Score interpretation: 0-4 (minimal anxiety), 5-9 (mild), 10-14 (moderate), 15-21 (severe anxiety).
Suicidality as measured by the C-SSRS (Columbia-Suicide Severity Rating Scale)5 weeksThe C-SSRS assesses the presence and severity of suicidal ideation and behavior. Suicidal ideation severity scores range from 0 to 5 (0=no ideation, 1=wish to be dead, 2=non-specific active suicidal thoughts, 3=active suicidal ideation with methods, 4=suicidal intent, 5=suicidal intent with plan), with higher scores indicating greater severity (worse outcome). The scale also captures suicidal behavior as binary yes/no responses.
