| Purpose: |
|
This is a 6-week, randomised, multicenter, double-blind, placebo controlled, fixed dose
parallel group study to assess the efficacy and safety of orvepitant (30 and 60 mg/day)
versus placebo in subjects with a diagnosis of a Major Depressive Disorder, whose symptoms
are considered moderate or severe.
Following an initial screening visit, subjects fulfilling the study inclusion and exclusion
criteria will enter a pre-treatment screening phase to permit evaluation of the laboratory
and ECG assessments and to confirm eligibility for inclusion into the study. This screening
phase will be a minimum of 7 days, but no longer than 21 days. At the completion of the
screening period, eligible subjects will be randomised at the baseline visit to receive
either orvepitant 30mg/day, orvepitant 60mg/day or placebo (equal chance of receiving any of
the three possible treatments, i.e., a 1:1:1 ratio) for a six-week double-blind treatment
phase. Those subjects randomised to receive placebo will receive study medication identical
in appearance to that received by subjects assigned to receive orvepitant 30 or 60mg/day.
Efficacy will be assessed via standard depression symptom and severity rating scales or
questionaires. The Hamilton Depression Rating Scale (HAM-D) will be used as the primary
measure. Secondary efficacy endpoints include the Quick Inventory of Depressive
Symptomatology (QIDS-SR) and the Clinical Global Impression- Global Improvement and Severity
of Illness Scale (CGI-I and CGI-S, respectively).
Safety will be assessed by monitoring for adverse events (side effects) and through periodic
laboratory evaluations (blood tests), vital signs assessments (e.g., blood pressure, heart
rate, temperature) and heart function measurements (electrocardiograms, or ECGs).

| Study summary: |
|
The purpose of the current study is to test the safety and the anti-depressant effects of
orvepitant, an investigational antidepressant. Efficacy will be assessed using standard
depression symptom and severity rating scales (questionaires). The Hamilton Depression
Rating Scale (HAM-D) will serve as the primary measure of efficacy, and . Secondary efficacy
endpoints include the Bech Melancholia Scale (sum of items 1, 2, 7, 8, 10, and 13 of the
17-item HAM-D scale), the Quick Inventory of Depressive Symptomatology (QIDS-SR), the
Clinical Global Impression- Global Improvement and Severity of Illness Scale (CGI-I and
CGI-S, respectively), the HAM-D anxiety factor score (sum of items 10, 11, 12, 13, 15 and
17), the Cognitive and Physical Function Questionnaire (CPFQ) and a morning sleep
questionnaire.
Safety and tolerability will be assessed by monitoring adverse events (AEs or side effects),
physical examinations (including vital signs such as blood pressure and heart rate),
clinical laboratory assessments (blood tests), electrical recordings of the heart
(electrocardiograms or ECG's), the Columbia Suicidality Severity Rating Scale (CSSRS),
Sexual Function Questionnaire (SFQ), and weight change.
Blood samples will be taken at different time points to assess blood levels of orvepitant in
patients, allowing the relationship between amount of orvepitant in the body and efficacy to
be studied.
The primary objective of the study is to evaluate the antidepressant efficacy of orvepitant
(30 and 60mg/day) versus placebo (a "sugar pill", with no active ingredients). The
secondary objectives include assessing the safety and tolerability of orvepitant, assessing
the profile of appearance and disappearance of orvepitant in the body (blood) following
administration (i.e., assessing how long the drug remains in the body), and lastly to
examine the relationship between blood levels of the drug and efficacy (i..e, the change in
HAM-D total score relative to what it was before starting the study medication.
Following an initial screening visit, subjects fulfilling the study entrance criteria will
enter a pre-treatment screening phase to permit evaluation of the laboratory and
electrocardiogram assessments and to confirm eligibility for inclusion into the study. This
screening phase will be a minimum of 7 days, but no longer than 21 days. During the
screening period, subjects may undergo up to three different assessments of their depressive
symptoms, this may occur via a face-to-face interview or via an interview over the
telephone. Upon completion of the screening period, eligible subjects will be randomly
assigned at the baseline visit to one of three treatment regimens: orvepitant 30mg/day,
orvepitant 60mg/day or placebo for a six-week treatment phase. The chances of receiving each
of the three possible treatments will be equal. Orvepitant will be administered as tablets.
Those subjects randomised to receive placebo will receive study medication identical in
appearance to that received by subjects assigned to receive orvepitant.
During the treatment phase, subjects will be required to return to the clinic at the end of
Weeks 1, 2, 4 and 6. In addition, all subjects will be required to return for a follow-up
visit 14 days after the last dose of study medication. In addition, all subjects with
ongoing adverse events at the 14-day follow-up visit will be required to return for a
further follow-up visit 28 days after the last dose of study medication.
Male and female outpatients between the ages of 18 to 64 years inclusive with a primary
diagnosis of Major Depressive Disorder will be enrolled into this study. A total of
approximately 350 subjects are expected to be enrolled at approximately 20 different study
sites in the U.S. and Canada. |

met depression criteria for at least 8 weeks prior to the Screening Visit.
- Subjects with symptom severity considered to be at least moderate to severe by the
investigator.
- Women of childbearing potential are only eligible IF they commit to consistent and
correct use of an acceptable method of birth control that must be documentation at
