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
| Measure | Time frame | Description |
|---|---|---|
| Cue-Induced Craving | 5 weeks | Craving 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
| Measure | Time frame | Description |
|---|---|---|
| Cravings | 5 weeks | Cannabis craving scale using the 12-item questionnaire, each item scored on a 1-7 sale. Higher scores (either average or summed) indicates stronger cravings. |
| Abstinence | 5 weeks | Percent days abstinent from cannabis |
| Weight | 5 weeks | Weight |
| Blood sugar | 5 weeks | Blood glucose |
| Serious adverse event | 5 weeks | Incidence of serious adverse events |
| Depression severity as measured by the Patient Health Questionnaire-8 (PHQ-8) | 5 weeks | Depression 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 weeks | The 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 weeks | The 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. |
