Intervention / Treatment
Detailed Description
Subjects will be randomized to 1 of 10 treatment sequences according to a two 5 x 5 William squares design. To maintain blinding, subjects will be required to ingest eight capsules with approximately 240 mL water on each study drug administration day.
Serial pharmacodynamic (PD) evaluations will be conducted up to 24 hours after each study drug administration. Pharmacokinetic (PK) samples will be obtained to confirm exposure to EB-1020. Safety monitoring will include recording of adverse events (AEs), regular assessments of vital signs measurements, 12-lead electrocardiogram (ECG) findings, and continuous telemetry monitoring for at least 3 hours after study drug administration.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Maximum effect (Emax) on Drug Liking visual analog scale (VAS)
Time Frame: within 24 hours post-dose
|
Drug liking VAS is one of the measures of balance of effects that assesses the degree that a participant likes a drug effect at the time the question is being asked (that is, at the moment).
It is scored using a 100 millimeter (mm) bipolar visual analogue scale (VAS) anchored in the center with a neutral anchor of "neither like nor dislike" (score of 50 mm), on the left with "strong disliking" (score of 0 mm) and on the right with "strong liking" (score of 100 mm).
|
within 24 hours post-dose
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Drug Liking VAS (minimum effect [Emin] and time-averaged area under the effect curve to 12 hours after study drug administration [TA_AUE])
Time Frame: within 24 hours post-dose
|
Drug liking VAS is one of the measures of balance of effects that assesses the degree that a participant likes a drug effect at the time the question is being asked (that is, at the moment).
It is scored using a 100 millimeter (mm) bipolar visual analogue scale (VAS) anchored in the center with a neutral anchor of "neither like nor dislike" (score of 50 mm), on the left with "strong disliking" (score of 0 mm) and on the right with "strong liking" (score of 100 mm).
|
within 24 hours post-dose
|
Overall Drug Liking VAS (Emax/Emin)
Time Frame: within 24 hours post-dose
|
Overall drug liking VAS is one of the measures of balance of effects that assesses the participant's global perception of drug liking (that is, effects over the whole course of the drug experience including any carryover effects).
A 100 mm bipolar VAS is used to assess response based on a score ranging from 0 mm to 100 mm (0 mm = "strong disliking", 50 mm= "neither like nor dislike", and 100 mm= "strong liking").
|
within 24 hours post-dose
|
Take Drug Again VAS (Emax)
Time Frame: within 24 hours post-dose
|
Take drug again VAS is one of the measures of balance of effects.
It is a subjective assessment of the degree to which a participant would desire to take the drug again if given the opportunity.
It is presented on a 100 mm bipolar VAS with score ranging from 0 mm to 100 mm (score of 0 mm = "definitely not", 50 mm = "do not care", and 100 mm = "definitely so").
|
within 24 hours post-dose
|
High VAS (Emax and TA_AUE)
Time Frame: within 24 hours post-dose

ARCI-A scale (Emax and TA_AUE)
Time Frame: within 24 hours post-dose
|
ARCI-A is measure of other stimulant effects.
It is a set of 13 questions in which each question contributes to total score.
Participants select 'False' / 'True' for response.
One point given for each response that agrees with scoring direction, true items receive score of 1 if answer 'True', false items receive score of 1 if answer 'False'.
No points if answer is opposite to scoring direction.
Score range: 0 to 13, higher score indicated higher other subjective effects.
|
within 24 hours post-dose
|
ARCI-BG scale (Emax and TA_AUE)
Time Frame: within 24 hours post-dose
|
ARCI-BG is measure of other subjective effects.
It is a set of 13 questions in which each question contributes to total score.
Participants select 'False' / 'True' for response.
One point given for each response that agrees with scoring direction, true items receive score of 1 if answer 'True', false items receive score of 1 if answer 'False'.
No points if answer is opposite to scoring direction.
Score range: 0 to 13, higher score indicated higher other subjective effects.
|
within 24 hours post-dose
|
Alertness/Drowsiness VAS (Emax and TA_AUE)
Time Frame: within 24 hours post-dose
|
Alertness/Drowsiness VAS is one of the measures of sedative effects.
It is scored using a 100 mm bipolar VAS anchored in the center with a neutral anchor of "neither drowsy nor alert" (score of 50 mm), on the left with "very drowsy" (score of 0 mm) and on the right with "very alert" (score of 100 mm).

|
Drug similarity VAS is one of the measures of other subjective effects.
It assesses the similarity of the drug recently received by the participant on a 100 mm unipolar VAS, where responses are unidirectional and range from a response of 'none' (score of 0 mm= not at all similar) to 'extremely' (score of 100 mm= very similar).
Recently received drugs were compared with placebo, benzodiazepines, codeine/morphine, Tetrahydrocannabinol (THC), pseudoephedrine.
