Arm Label

Oxytocin

Placebo

Arm Description

20 IU of intranasal oxytocin twice per day for the first week, 40 IU of intranasal oxytocin twice per day for the following 3 weeks, one week wash out, 4 week placebo trial.

Outcomes

Primary Outcome Measures

Total Score on Montgomery-Asberg Depression Rating Score (MADRS)
The MADRS is a clinician-rated assessment used to measure the severity of depressive episodes in patients with mood disorders. The measure contains 10 items and each item is scored in a range of 0 to 6 points, with higher score indicating increased depressive symptoms.

Secondary Outcome Measures

Global Assessment of Functioning (GAF)
The GAF considers psychological, social, and occupational functioning on a hypothetical continuum of mental health illness. Scores on the GAF range from 1 (extremely severe) to 100 (superior functioning).
Clinical Global Impression-Severity of Illness (CGI-S)
The CGI-S is used to evaluate changes in overall severity of illness. Scores on the CGI-S range from 1 (not at all) to 7(among the most extremely ill).
Clinical Global Impression-Global Improvement (CGI-I)
The CGI-I is a global assessment to evaluate the subjects' improvement or worsening from baseline. Scores on the CGI-I scale range from 1 (very much improved) to 7 (very much worse).
Young Mania Rating Scale (YMRS)
The YMRS is an 11-item assessment used to assess the severity of mania in patients with a diagnosis of bipolar disorder. Ratings are based on patient self-reporting, combined with clinician observed.
Hamilton-Anxiety Scale (HAM-A)
The HAM-A is a clinician administered scale for the evaluation of anxiety symptoms. The HAM-A consists of 14 items of which each item is scored 0 (not present) to 4 (very severe).
Reading Trust in the Mind's Eye Test
The subject will view approximately 16 faces and asked to rate trustfulness of the person in the picture.
Profile of Mood States (POMS)
The POMS is a self-rated scale to assess current mood states. The POMS consists of 65 words that the subject will rate from 1 (not at all) to 5 (extremely) based on how he/she feels at the time.
Arizona Sexual Experience Scale (ASEX)
The ASEX is a self-rated scale to assess sexual functioning. The ASEX consists of 5 items that the subject will rate from 1 (Extremely strong, easily, or satisfying) to 6 (Absent or never) based on how he/she feels at the time.
Peabody Picture Vocabulary Test
The subject is read a series of words and is shown line drawings and is asked to match the word to the drawing.
California Verbal Learning Test
The subject is read a list of words and asked to repeat them back first after the list is read and again 20 minutes later.
Letter Number Sequencing Memory Test
The examinee is read a combination of numbers and letters and is asked to recall the numbers first in ascending order and then the letters in alphabetical order. Each item consists of three trials, and each trial is a different combination of numbers and letters.
Continuous Performance Test (CPT)
Patients are told that they will see a series of letters presented on a screen. They are told to click a computer mouse only when they see the "target" stimulus, for instance the letter "X", and must refrain from clicking if they see any other letter presented.

5. Study Description

Brief Summary
The objective of the study is to compare the efficacy of intranasal oxytocin versus intranasal placebo to improve depression symptoms in patients with Major Depressive Disorder (MDD) or Dysthymia Disorder.
Detailed Description
Depression patients treated with even the best currently available antidepressant drugs continue to experience significant symptoms. There is a strong need for better treatments including treatments that can safely be given adjunctively with concurrent antidepressants in order to improve overall efficacy of treatment. Oxytocin is a neurohypophyseal peptide best known for its role as a neurohormone involved in parturition and lactation. In addition to these well established peripheral effects, there is a compelling body of converging evidence indicating that oxytocin plays a critical role in the regulation of a number of diverse centrally-mediated behavioral and cognitive processes that are highly relevant to mood regulation and mood disorders, including social attachment (Argiolas and Gessa 1990; McCarthy and Aaltemus 1997). Each subject will be enrolled for a 8 week treatment period after a screening phase. Study procedure involves weekly clinic visits as an outpatient. Twenty patients will be randomly assigned to either 40 IU oxytocin twice daily or vehicle placebo. After 4 weeks, treatments will be crossed over such that subjects that received oxytocin will receive placebo and vice versa. The study ratio is 1:1. Dose of oxytocin is based upon previous studies in humans showing improvement in psychiatric populations related changes in behavior and brain function (Kosfeld et al, 2005; Kirsch 2005; Heinrich M 2003). The total study duration for each individual subject will be approximately 9 weeks, which includes up to 31-day screening period, a baseline (randomization) visit, four week treatment period, 1 week washout, baseline 2 visit, and four weeks cross over treatment.
