A Randomized, Double-Blind, Parallel-Group, Placebo-Controlled, Fixed Dose Study Evaluating the Efficacy and Safety of Orvepitant in Subjects With Major Depressive Disorder

Stopped early · Phase 2 · Has a placebo group

Conditions studied: Depressive Disorder, Major

In brief

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).

Who can join

Age: 18 and older, up to 64. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Subjects must have the ability to comprehend the Informed Consent Form.
Male or female outpatients, aged 18-64, inclusive.
A primary diagnosis of major depressive disorder, single episode or recurrent
Subjects must, in the investigator's opinion and based on the subject's history, have 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 each visit

You may not qualify if…

Subjects whose mood-related symptoms are better accounted for by a diagnosis other than depression; subjects diagnosed with Alzheimer's Disease or other form of dementia; subjects diagnosed with a current/recent eating disorder such as anorexia nervosa or bulimia; subjects with a diagnosed history of schizophrenia, schizoaffective disorder, or Bipolar Disorder.
Subjects with any history of a significant abnormality of the neurological system (including dementia and other cognitive disorders or significant head injury) or any history of seizures (convulsions).
Subjects have a positive urine test at screening for illegal drug use and/or who have a history of substance abuse or dependence (alcohol or drugs) within the past 12 months.
Subjects who are currently receiving regularly scheduled psychotherapy (individual or group), plan to start psychotherapy during the trial or have received regularly scheduled psychotherapy during the 12 week period prior to the Screening Visit.
Subjects who have a history of failing to respond to adequate treatment with an antidepressant, i..e, failure to improve following administration of at least two other antidepressants, each given for at least 4 weeks.
Subjects who, in the investigator's judgement, pose a homicidal or serious suicidal risk, have made a suicide attempt within the 6 months preceding screening or who have ever been homicidal.
Subjects who have received the following treatments for depression in the past: electroconvulsive therapy (ECT), vagal stimulation, or transcranial magnetic stimulation (TMS) within the 6 months prior to the Screening Visit.
Subjects with an unstable medical disorder; or with a disorder that otherwise would likely interfere with the activity of the study medication (orvepitant).
Subjects have any screening laboratory abnormality that in the investigator's judgement is considered to be clinically significant.
Subjects with an abnormal thyroid test at the Screening Visit. Subjects maintained on thyroid medication must have normal thyroid levels for a period of at least six months prior to the Screening Visit.
Subjects have any screening electrocardiography (ECG) finding that in the investigator's judgement is considered to be clinically significant.
Women who have a positive pregnancy test at the Screening Visit, a positive urine dipstick test at the Baseline (Randomization) Visit, or who are lactating or planning to become pregnant within the 4 months following the Screen Visit.
Subjects who have taken other psychoactive drugs within two weeks prior to the Baseline Visit i.e. at any time during the Screening period. This includes "over-the-counter" psychoactive medications such as St. John's Wort and SAM-e.
Subjects who have taken other drugs within 2 weeks prior to the Baseline visit which the investigator feels may interact with the study medication.
Subjects who are currently participating in another clinical trial in which the subject is or will be exposed to an investigational or non-investigational drug or device, or has done so within the preceding month for studies unrelated to depression, or 6 months for studies related to depression.
Subjects who have no contact with an adult on a daily basis. This would exclude subjects who are not living with at least one other adult or subjects who do not have an adult who contacts them on a daily basis.
