What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Time Frame: Baseline up to 7-10 days after last dose of study drug, up to 26 days
An adverse event (AE) was any untoward medical occurrence in a clinical investigation participant administered a product or medical device; the event need not necessarily have a causal. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; life threatening (immediate risk of death); initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect. Any events occurring following start of treatment or increasing in severity were counted as treatment emergent. AEs included both serious and non-serious AEs.
Baseline up to 7-10 days after last dose of study drug, up to 26 days
Number of Participants With Supine and Standing Vital Signs Meeting Categorical Summarization Criteria
Time Frame: Baseline up to 7-10 days after last dose of study drug, up to 26 days
Vital Signs tests included systolic and diastolic blood pressure (BP) and pulse rate of seated supine and standing . Vital signs categorical summarization criteria were 1), supine and standing BP: systolic (SBP) greater than or equal to (>=) 30 millimeters of mercury (mm Hg) change from baseline, systolic less than (<) 90 mm Hg; diastolic BP (DBP) >=20 mm Hg change from baseline, diastolic <50 mm Hg; 2), supine and standing pulse rate <40 or greater than (>) 120 beats per minute (bpm).
Baseline up to 7-10 days after last dose of study drug, up to 26 days
Number of Participants With Electrocardiogram (ECG) (Standard 12-Lead) Data Meeting Categorical Summarization Criteria
Time Frame: Baseline up to 7-10 days after last dose of study drug, up to 26 days
ECG categorical summarization criteria were 1), time from ECG Q wave to the end of the S wave corresponding to ventricle depolarization (QRS interval): more than or equal to (>=) 200 milliseconds (msec); for percent change(PChg), >=25 percent (%) increase when baseline (b)>100 msec; or increase >=50% when b less than or equal to (<=)100 msec; 2), the interval between the start of the P wave and the start of the QRS complex, corresponding to the time between the onset of the atrial depolarization and onset of ventricular depolarization (PR interval): >=300 msec; >=25percent (%) increase when b >200 msec; or increase >=50% when b <=200 msec; 3), time from ECG Q wave to the end of the T wave corresponding to electrical systole corrected for heart rate using Fridericia's formula (QTcF interval): absolute value >=450 - <480 msec, >=480-<500 msec and >=500 msec; increase from b >=30 - <60 and >=60 msec
Baseline up to 7-10 days after last dose of study drug, up to 26 days
Number of Participants With Blood and Urine Safety Laboratory Test Abnormalities
Time Frame: Baseline up to Day 15
The total number of participants with blood and urine laboratory test abnormalities (without regard to baseline abnormality) was assessed. Clinical laboratory tests included hematology, chemistry, urinalysis, and some other tests.
Baseline up to Day 15
Number of Participants With New Onset and Worsening of Post Baseline Suicidality in Columbia Suicide Severity Rating Scale (C-SSRS) on Day 1, Day 7 and Follow-up.
Time Frame: Baseline, Days 1,7 and follow-up (7-10 days after last dose of study drug, up to 26 days)
The C-SSRS was an interview based rating scale to systematically assess suicidal ideation and suicidal behavior. Versions were available for Screening/Baseline and follow-up visits. Post-baseline suicidality was displayed without regard to baseline and as new onset or worsening relative to baseline. A participant was considered to have a new onset of suicidality if the participant reported no ideation and no behavior at the baseline assessment. A participant was considered to have a worsening of suicidality if the participant moved to a lower numbered Columbia Classification Algorithm of Suicide Assessment (C-CASA) category (observed in categories 1-4) than was reported at baseline.
Baseline, Days 1,7 and follow-up (7-10 days after last dose of study drug, up to 26 days)
Change From Baseline to Day 13 of Wechsler Memory Scale (WMS III) Spatial Span + Letter Number Span Composite Score (Working Memory Domain)
Time Frame: Baseline, Day 13
MCCB measures cognitive function across cognitive domains and is comprised of 10 independent tests assessing 7 cognitive domains (speed of processing, attention/vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition). A subset of the MCCB cognitive domain was used to assess working memory of participants. Total score range of this subset ranges from 40 (minimum score) to 60 (maximum score), with higher scores indicating better cognitive function.
Baseline, Day 13
Change From Baseline in Blood Oxygen Level Dependent (BOLD) fMRI Activation Parameter Estimates (Z-scores) in Anterior Ventral Striatum Region of Interest (ROI) for the Contrast of Cue Gain > Cue No Gain in Monetary Incentive Delay (MID) Task on Day 15
Time Frame: Baseline, Day 15
MRI parameter estimates refer to the 90th percentile Z-statistics across all voxels within the Region of Interest (ROI). This task provided a measure of reward anticipation and reward consummation. One of 3 shapes was presented on the screen (each uniquely associated with gain, loss and neutral) as a cue, and participants were instructed to respond to each cue, using their dominant hand, by pressing in response to a subsequent target that appeared for a variable length of time. Baseline was defined as Day 0 assessment. To be included in analysis participants must have complete Monetary Incentive Delay (MID) data at both Baseline and post-baseline, without excessive head motion. Participants with MID <40% at baseline were excluded from the analysis and summary statistics. Scores were not bounded by a minimum or maximum range, higher z-score implies a greater motivation of the participant by the prospect of monetary gain than no monetary gain.
Baseline, Day 15

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
