About this trial

This research is being done to evaluate whether suvorexant may reduce the use of, subjective liking, and demand for various drugs.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Age between 18 and 65 years old

Meets Diagnostic and Statistical Manual-5 criteria for Opioid Use Disorder (OUD) (moderate or severe)

Lifetime substance use history criterion [blinded]

Medically cleared to take suvorexant and blinded study medications

Disqualifiers

Pregnant or breast feeding

Seeking opioid use treatment

Significant mental health or physical disorder that is expected to interfere with study participation as assessed by the study physicians or medical staff

Known contraindications or allergies to suvorexant and/or the blinded study medications

Treatments tested in this trial

  • Drug A (Blinded Drug)

    Drug

    Participants will receive a double-blinded oral study medication as part of their daily sessions and will provide feedback regarding the effects of the medication on various measures. Though the study medications are FDA approved, they are being used here for a non-FDA approved purpose (though the FDA has provided permission to use these drugs in this study).

  • Drug B (Blinded Drug)

    Drug

    Participants will receive a double-blinded oral study medication as part of their daily sessions and will provide feedback regarding the effects of the medication on various measures. Though the study medications are FDA approved, they are being used here for a non-FDA approved purpose (though the FDA has provided permission to use these drugs in this study).

  • Drug C (Blinded Drug)

    Drug

    Participants will receive a double-blinded oral study medication as part of their daily sessions and will provide feedback regarding the effects of the medication on various measures. Though the study medications are FDA approved, they are being used here for a non-FDA approved purpose (though the FDA has provided permission to use these drugs in this study).

  • Drug D (Blinded Drug)

    Drug

    Participants will receive a double-blinded oral study medication as part of their daily sessions and will provide feedback regarding the effects of the medication on various measures. Though the study medications are FDA approved, they are being used here for a non-FDA approved purpose (though the FDA has provided permission to use these drugs in this study).

  • Suvorexant (20mg/day)

    Drug

    Double blind administration of suvorexant once per day during residential stay until discharge.

  • Placebo

    Drug

    Double blind administration of placebo once per day during residential stay until discharge.

Treatment groups

75 Participants
are divided into 2 treatment groups
Group A: Suvorexant (20mg/day)Experimental treatment 5 interventions
Group B: PlaceboPlacebo comparator 5 interventions

Trial outcomes

Primary outcomes

1

Demand Intensity

Consumption of blinded drug at unconstrained price as measured by an incentivized demand task. Minimum value is 0, maximum value is not constrained. Higher scores indicate more drug consumption at unconstrained price (a worse outcome).

Time frame
Upon completion of experimental session (~8 hours post drug administration)
2

Demand Elasticity

Changes in blinded drug consumption with changes in price as measured by an incentivized demand task. There is no minimum or maximum value. Higher scores indicate greater drug price sensitivity (a better outcome).

Time frame
Upon completion of experimental session (~8 hours post drug administration)
3

Cross-Price Elasticity

Change in consumption of price-fixed good based on change in price of price varying good. Positive values indicate a substitute, negative values indicate a complement, and zero values indicate an independent commodity.

Time frame
After Experimental Session 4

Secondary outcomes

1

Total Mean Sleep Time

Mean total number of minutes slept per night as measured by actigraphy and self-reported sleep diary. Mean total sleep time will be collected daily.

Time frame
Through study completion, up to two weeks
