Arms Assigned Interventions
Active Comparator: Oxytocin Drug: Oxytocin
20 IU of intranasal oxytocin twice per day for 8 weeks, and a placebo (oral) for the 8 week trial
Active Comparator: Oxytocin and Tibolone Drug: Oxytocin and Tibolone
20 IU of intranasal oxytocin twice per day for 8 weeks, and 2.5mg oral tibolone for the 8 week trial
Other Name: Livial (tibolone)
Placebo Comparator: Placebo Drug: Placebo

Detailed Description:

We are examining the efficacy and safety of oxytocin or oxytocin and tibolone with an antidepressant (SSRIs) in treatment resistant depression in a double-blind randomized clinical trial.

A secondary objective is the evaluation of neurobiological factors contributing to drug efficacy in treatment resistant depression.


Ages Eligible for Study:   18 Years to 45 Years   (Adult)

Inclusion Criteria:

  • Women
  • 18-45 years

  • Active malignancy, or treatment for malignancy in the preceding 6 months (excluding non-melanotic skin cancer)
  • Alcohol consumption in excess of 3 standard drinks per day
  • Lactose intolerance
  • An abnormal thyroid stimulating hormone (TSH) value at screening confirmed by a Free T4 outside the normal laboratory range (patients with an abnormal TSH, normal Free T4 and no clinical signs or symptoms of thyroid disease, with or without replacement treatment, may be admitted to the study).
  • A history of allergic reactions to androgens (oral or patch)
