Trial Overview

Trial Outcomes

Intensity of Suicidal Ideation

"Intensity of Suicidal Ideation was monitored over the course of the trial by the second section of the Columbia Suicide Severity Rating Scale (CSSRS). This section is only administered if the patient answers yes to the first section. The section consists of 5 questions that refer to the most severe level of ideation endorsed in the first section of the CSSRS. The total score ranges from 2 to 25, with a higher number indicating more intense ideation and greater risk.~Only lifetime intensity of suicidal ideation was explored as the patient had no suicidal ideation from the month prior to beginning the study to the completion of the study" (NCT01917318)
Timeframe: Baseline

Aggression

Aggression was measured by the Modified Overt Aggression Scale (MOAS).This assessment measures four types of aggressive behavior (verbal, aggression against property, autoaggression, and physical aggression) . Total scores on the MOAS range from 0-40, with a higher score indicating more aggressive behavior. (NCT01917318)
Timeframe: Randomization and 8 weeks of treatment, during both treatment periods

Change in Clinician Administered PTSD Scale (CAPS) Part B and D

"The Clinician-Administered PTSD Scale (CAPS) is a structured interview used to diagnose and assess PTSD. Part B of CAPS evaluates symptoms of re-experiencing. Part D evaluates avoidance and numbing.~CAPS-B scores range from 0 to 40 where higher scores indicate more symptoms. A score 0 means no re-experiencing symptoms.~CAPS-D scores range form 0 to 56 and higher scores indicate more symptoms. A score 0 means no avoidance or numbing symptoms.~The primary endpoint was changes in CAPS part B and D after 8 weeks of treatment." (NCT01917318)
Timeframe: Randomization and at the end of each treatment period. Placebo treatment lasted 8 weeks. Iloperidone treatment lasted 2 weeks.

Suicidal Behavior

The presence and severity os suicidal behavior was monitored over the course of the trial by the third section of the Columbia Suicide Severity Rating Scale (CSSRS). This sections consists of questions about 5 suicidal behaviors and non-suicidal self injurious behavior and it can be answered yes or no. The number of participants who experienced suicidal behavior is reported. (NCT01917318)
Timeframe: Total course of the study. CSSRS was administered during each study visit. Suicidal ideation during lifetime and during the month prior to screening were also explored

Suicidal Ideation

The presence of suicidal ideation was monitored over the course of the trial by the first section of the Columbia Suicide Severity Rating Scale (CSSRS). This first section of the scale consists of 5 questions that can be answered yes or no. The number of participants who reported experiencing suicidal ideation is reported. (NCT01917318)
Timeframe: Total course of the study. CSSRS was administered during each study visit. Suicidal ideation during lifetime and during the month prior to screening were also explored

Decrease in Bulimia Symptoms

EDI-3 (Eating Disorder Inventory 3 Scale) is a pencil and paper test consisting of 91 items and 12 sub-scales. The main scales are the drive for thinness and the bulimia scales, the remaining sub-scales are: low self-esteem, body dissatisfaction, maturity fears, personal alienation, interpersonal alienation, interpersonal insecurity, perfectionism, interoceptive deficits, emotional dysregulation, and asceticism. The response options are based on a 6-point Likert-type scale are: Always, Usually, Often, Sometimes, Rarely, and Never. There are six composite scores, 12 primary scores, and three response style validity indicators. Software is used to calculate the raw scores, composite scores, validity scale scores and the T-scores. The t-score for the Bulimia scale will be used for this analysis with a range of 22-66. Higher scores indicate the likelihood of an eating disorder. A higher t-score on the bulimia scale indicates a worse outcome. (NCT02382848)
Timeframe: 3 weeks

Decrease in Depressed Mood as Measured by the HDRS (Hamilton Depression Rating Scale) and Subject Interview

Rating scales and subject interview will be used to determine if there is a decrease in depressed mood among participants undergoing drug intervention. The HDRS (Hamilton Depression Rating Scale) consists of 17 items, some scored on a 5-point scale (0-4) and others scored on a 3-point scale (0-2). Items from the scale can be summed to give a total score ranging from 0 to 50, with higher scores indicating a worse outcome. This analysis is based on a single item from the scale (Depressed Mood, measured on a 5-point scale) where a higher score again indicates a worse outcome. (NCT02382848)
Timeframe: 3 weeks

Decrease in Frequency of Nightmares Using the Sleep-50 Questionnaire

"The individual question about frightening dreams from the Nightmares Subscale of a self-administered questionnaire (Sleep-50 Questionnaire), will be used to determine if there is a decrease in frequency of nightmares in patients undergoing drug intervention. For each question, respondents are provided with a scale ranging from 1 (not at all) to 4 (very much) and are asked to indicate the extent to which the statement has matched their experience over the study time frame. The scale values range from 1-4, where a lower value indicates lower frequency of nightmares. A higher score is a worse outcome." (NCT02382848)
Timeframe: 3 weeks

Decrease in Self Harm Thoughts as Measured by the HDRS and Subject Interview

Rating scales and subject interview will be used to determine if there is a decrease in self harm among participants undergoing drug intervention. The HDRS (Hamilton Depression Rating Scale) consists of 17 items, some scored on a 5-point scale (0-4) and others scored on a 3-point scale (0-2). Items from the scale can be summed to give a total score ranging from 0 to 50, with higher scores indicating a worse outcome. This analysis is based on a single item from the scale (Self Harm, measured on a 5-point scale) where a higher score again indicates a worse outcome. (NCT02382848)
Timeframe: 3 weeks

Decrease in Total CAPS Score (PTSD)

The CAPS (Clinician administered PTSD) rating scale consists of 30 questions rated on a 0-4 point scoring system and patient interview will be used to determine if there is a decrease in PTSD Symptoms among participants undergoing drug intervention. 17 of these questions are used to calculate the total severity score used in this analysis. This is done by summing the frequency and intensity ratings (each ranging from 0-4) for each of the 17 questions. The total severity score can have a range of 0-136. A higher score on this scale indicates a worse outcome. (NCT02382848)
Timeframe: 3 weeks

Change in Recurring Distressing Dreams and Difficulty Falling and Staying Asleep Items of the CAPS

"Item B-2 recurrent distressing dreams of the event is a single item from teh Clinician Administered PTSD Scale (CAPS). The rating consists of two parts: Frequency plus Intensity. Symptom frequency rated 0 to 4. Symptom intensity rated 0 to 4. Frequency plus Intensity ratings equal the total score. The total minimum score = zero. The total maximum score = 8. A higher score is worse; a lower score is better. This outcome measure evaluates the change in score from Baseline to Week 8." (NCT00183430)
Timeframe: Baseline to Week 8

Change in Sleep Assessed by the Pittsburgh Sleep Quality Index

Pittsburgh Sleep Quality Index is a self-report questionnaire assessing sleep quality and disturbances over a 1-month time interval. A global score is obtained by summing the seven component subscales (total score range: 0-21). A score of 5 or less indicates good sleep quality. A score of more than 5 indicates poor sleep quality. Change is measured from Baseline to Week 8. (NCT00183430)
Timeframe: Baseline to Week 8

Clinical Global Impression of Change

The Clinical Global Impression of Change is a 7-point scale that rates global change compared to baseline (1=markedly improved, 2=moderately improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=moderately worse, 7=markedly worse). The Clinical Global Impression of Change is used to determine the impact of treatment effects on meaningful and distinct change in overall sense of well-being and functioning. This outcome measure evaluates change from Baseline to Week 8. (NCT00183430)
Timeframe: Baseline to Week 8
