Trial Outcomes & Findings for The Effects of Suvorexant on Sleep, Stress, and Cue-reactivity in Methamphetamine Use Disorder (NCT NCT05711862)

NCT ID: NCT05711862

Last Updated: 2025-04-29

Results Overview

Each component score of the PSQI ranges from 0 to 3, with 3 indicating the greatest dysfunction or disturbance. The seven component scores are then summed to obtain a global PSQI score, which ranges from 0 to 21, higher score indicating a worse outcome. The global PSQI score is reported.

PRIMARY outcome

Timeframe: 7 days

EEG will be used to assess electrical activity in the brain, specifically, to assess alpha power, which is the level of activity in the 8-12Hz frequency range. Resting state EEG means that EEG will be assessed during wakeful rest. Alpha power will be assessed in each of the 4 brain lobes (frontal, central, parietal, and occipital) for 3 minutes during eyes closed wakeful rest and also for 3 minutes during eyes open wakeful rest. Alpha Power will be reported in microvolts squared (μV²). Higher alpha power indicates more sleepiness and lower alpha power indicates less sleepiness

PRIMARY outcome

Timeframe: 7 days

The Picture Viewing Task will be used to elicit the late positive potential (LPP), reflecting the motivational salience of a stimulus. During this task, participants are asked to view a slideshow of images including pleasant, unpleasant, neutral, and Methamphetamine-related images. The amplitude of the LPP in microvolts in response to visual stimuli is reported.

Timeframe: baseline, about 32 minutes after the start of the cold pressor task

During the cold pressor task (CPT), participants will submerge their dominant arm in an ice-water bath for up to 2 minutes. Saliva samples will be collected before and after the CPT, and cortisol levels in the saliva samples will be assessed. The change in cortisol level will be reported as \[(cortisol level at post cold pressor task) - (cortisol level pre cold pressor task)\].
