Trial Overview

Trial Outcomes

Change in Clinician Administered PTSD Scale for DSM-IV (CAPS) Recurrent Distressing Dreams Item

"Item B-2 recurrent distressing dreams of the event is a single item from the Clinician Administered PTSD Scale. The rating consists of two parts: Frequency and Intensity. Symptom frequency rated 0 to 4. Symptom intensity rated 0 to 4. Frequency plus Intensity ratings equal the total score. A higher score is worse; a lower score is better. This outcome measure evaluates the change in score from Baseline to Week 15." (NCT00990106)
Timeframe: Baseline to Week 15

Change in Pittsburgh Sleep Quality Index (PSQI)

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 15. (NCT00990106)
Timeframe: Baseline to Week 15

Clinical Global Impression of Change (CGIC)

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 CGIC is used to determine the impact of treat effects on meaningful and distinct change in overall sense of well-being and functioning. This outcome measures the proportion of responders who were rated markedly or moderately improved at Week 15 compared to Baseline. (NCT00990106)
Timeframe: Change from Baseline to Week 15

ADCS-ADL-Severe

"The ADCS-ADL-Severe questionnaire is a secondary outcome measure aimed at detecting functional decline in people with severe AD. This scale is best suited for evaluating people with MMSE scores below 15/30, or equivalent. Questions are administered to a qualified caregiver informant about a set of 19 basic and instrumental ADL. Instrumental ADL are selected to be relevant to this level of severity of dementia, e.g., obtaining a beverage, turning lights on and off, turning a faucet on and off. Performance of each of these activities during the past 4 weeks, as well as the level of performance, are rated. A total score is derived by summing scores across items, and ranges from 0 (maximal impairment) to 54 (maximally independent function).~This outcome is the change from baseline to week 12." (NCT03710642)
Timeframe: 12 weeks

ADCS-Clinical Global Impression of Change in Agitation (ADCS-CGIC-A)

"The ADCS-CGIC-A is the primary outcome measure. It will be anchored to disruptive agitation, the target behaviors in this study. It measures whether the effects of active treatment are substantial enough to be detected by a skilled and experienced clinician on the basis of a direct examination of the participant and an interview of the participant's primary caregiver and other LTC facility staff. The baseline assessment is qualitative therefore there is no score at baseline; post-baseline scores represent a change score compared to baseline.~The ADCS-CGIC-A is a 7-point scale that is structured as the clinician's assessment of change from baseline compared to the ADCS-CGIC-A Baseline Worksheet. There is no baseline score; post-baseline scores range from 1 (improvement) to 7 (worsening). A score of 1-2 indicates clinically meaningful improvement; a score of 3-5 indicates no clinically meaningful change; a score of 6-7 indicates clinically meaningful worsening." (NCT03710642)
Timeframe: From Baseline through Week 12.

Caregiver Distress on NPI/NPI-NH

"Comparison of effects on caregiver distress/occupational disruptiveness scores on the NPI/NPI-NH. Minimum score is 0 and maximum score is 60. A higher score is a worse outcome.~This outcome is the change from baseline to week 12." (NCT03710642)
Timeframe: 12 weeks

Neuropsychiatric Inventory (NPI)/Neuropsychiatry Inventory-Nursing Home Version (NPI-NH)

"The NPI was designed to characterize the neuropsychiatric symptoms and psychopathology of patients with AD and other dementias residing in the community about which information was obtained from family caregivers. The content of the questions and their scoring in the NPI-NH are identical to those of the NPI except for some slight rephrasing to be consistent with the LTC environment where information is gathered from professional caregivers. Assessment of the impact of behavioral disturbances on family and professional caregivers, is assessed by a caregiver distress scale in the NPI and an occupational disruptiveness scale in the NPI-NH; scoring of this component remains identical. Minimum score is 0 and highest score is 144. A higher score means a worse outcome.~This outcome is the change from baseline to week 12." (NCT03710642)
Timeframe: 12 weeks

Rescue Medication: Total mg Lorazepam Administered

Cumulative total dose of Lorazepam rescue medication administered during the trial. Information on the total mg rescue lorazepam administered will be collected as additional secondary outcome measures. If prazosin is more effective than placebo, it is predicted that participants randomized to prazosin will be prescribed lower cumulative mg of rescue lorazepam for management of persistent or worsening disruptive agitation. (NCT03710642)
Timeframe: 12 weeks

Responder Analysis on CGIC-A

Comparison of proportions of responders versus non responders on the ADCS-CGIC-A. Responders are defined as those with moderate or marked improvement in agitation symptoms compared to baseline assessment. (NCT03710642)
Timeframe: 12 weeks

Study Discontinuations

Timeframe: 12 weeks

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)
