Trial Outcomes & Findings for A Randomised, Double-Blind, Placebo-Controlled Study Evaluating the Efficacy and Safety of Orvepitant in Subjects With Major Depressive Disorder (NCT NCT00880048)

NCT ID: NCT00880048

Last Updated: 2017-10-13

Results Overview

HAM-D was use to measure the severity of depressive symptoms in participants with primary depressive illness. It was a checklist of items that were ranked on a scale of 0-4 or 0-2. Items with quantifiable severity were scored 0 (lowest severity) to 4 (greatest severity); The HAM-D total score was calculated by summing the individual response scores. The lowest possible score was 0 (absence of depression) and the highest possible score was 52 (most severe measure of depression). For the last observation carried forward analyses, the most recent post randomization total score (as opposed to individual responses) was "carried forward" and used in the calculation of the change from randomization (Baseline) value. If the responses to more than 1 question were missing for a participant at a particular time point, the total score was not calculated. Change from Baseline in total score was the difference between HAM-D total score at the time point being analyzed and randomization.

The start of the 'maintained antidepressant response' was the time at which a participant demonstrates a 50% reduction from randomization in their HAM-D total score and where this response was maintained until the end of the treatment phase (week 6). Participants who met the 50% reduction at week 6 without having met it at week 4 were considered to have reached a maintained response, and therefore were censored at week 6. Where a participant met the criteria for maintained antidepressant response, the "time (in days) to maintained antidepressant response" was calculated as: (Date of assessment at which the maintained response commences minus Date of randomization) plus 1. Where a participant did not met the criteria for maintained antidepressant response, their time to response was censored at the last on-treatment assessment they undertake, up to and including the week 6 assessment.

The BECH scale was extracted from the HAMD-17 and comprised the 6 items (sum of items 1, 2, 7, 8, 10, and 13 of the 17-item HAM-D scale): Depressed Mood, Feelings of Guilt, Work and Activities, Retardation, Anxiety Psychic and Somatic Symptoms General. The BECH Total Score was calculated by summing the individual response scores. It was a checklist of items that were ranked on a scale of 0-4 or 0-2. The lowest possible score was 0 (absence of depression) and the highest possible score was 22 (most severe measure of depression). Due to the small number of items , missing data was not imputed for the BECH Total Score. If any of the 6 items above were missing, the total score was not calculated at that visit. Value at randomization was the Baseline value. Change from Baseline in BECH Total Score was the difference between BECH Total Score at the time point being analyzed to randomization.

QIDS-SR assessed symptoms severity of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnostic criterion for major depressive disorder. It consisted of 16 separate items, defining 9 DSM-IV symptom criterion domains. A total score was obtained by summing scores on each domain. The lowest possible score was 0, which represented an absence of depression; the highest possible score was 27, which represented the most severe measure of depression. Due to the small number of items, missing data was not imputed for the QIDS-SR total score. If any of the 9 domains above were missing, the total score was not calculated at that visit. Value at randomization was the Baseline value. Change from Baseline in total score was the difference between QIDS total score at the time point being analyzed to randomization. If no post- randomization scores were available, change from Baseline was set to missing.

The anxiety score was extracted from the HAM-D-17 and comprises of items 10, 11, 12, 13 and 15 from the HAM-D scale. The anxiety score was calculated by summing the individual response scores to these questions. It was a checklist of items that were ranked on a scale of 0-4 or 0-2. The lowest possible score was 0 (absence of depression) and the highest possible score was 18 (most severe measure of depression). Due to the small number of items, missing data was not imputed for the anxiety score. If either of the anxiety items was missing, the total score was not calculated at that visit. Value at randomization was the Baseline value. Change from Baseline in anxiety score was the difference between the anxiety score at the time point being analyzed to randomization. If no post- randomization scores were available, change from Baseline was set to missing.

CPFQ was a brief self-report scale which was designed to measure cognitive and executive dysfunction in mood and anxiety disorders. The CPFQ comprised of 7 questions assessing each of the most common complaints of depressed participants reporting fatigue or cognitive/executive problems. Each question was rated on a scale of 1 to 6, with 1 indicating greater than normal functioning, 2, indicating normal functioning, and with higher numbers indicating poorer functioning. Two versions of the CPFQ were utilized during the study. The Baseline CPFQ requested the participant reflect back over the past month. For the treatment period, the CPFQ requested the participant reflect back over the past week. Value at randomization was the Baseline value. Change from Baseline in Total Score was the difference between CPFQ Score at the time point being analyzed to randomization. If no post- randomization scores were available, change from Baseline was set to missing.

The following variables were assessed in order to determine effects on sleep: total sleep time, sleep onset latency, number of nocturnal awakenings, wake time after sleep onset and sleep quality (from poor, assigned a score of 1, to excellent, assigned a score of 10). The refreshing value of the sleep was also determined (poor assigned a score of 1, to excellent, assigned a score of 10). Value at randomization was the Baseline value. Change from Baseline was calculated for each domain separately. Change from Baseline was the difference between score at the time point being analyzed to randomization. If no post- randomization scores were available, change from Baseline was set to missing.
