Primary Outcome Measures:
  • Y-BOCS Scores at 1st and Last Visit [ Time Frame: Week 0 to 17 ]
    OCD symptom change. This is the intention-to-treat analyses (with all 20 subjects included) rather than just the subjects who completed the treatment.

Secondary Outcome Measures:
  • BDI (Beck Depression Inventory) - First and Last Visit (Week 0 and Week 17). [ Time Frame: Week 0 to 17 ]

    Depression severity, such that higher scores on the BDI are reflective of more severe depression.

    BDI minimum score: 0 MDI maximum score: 63

  • BAI (Beck Anxiety Inventory) - First and Last Visit (Week 0 and Week 17) [ Time Frame: Week 0 to 17 ]

    Anxiety severity, such that a higher score on the BAI reflects more severe anxiety.

    Minimum value: 0 Maximum value: 63

  • QLESQ (Quality of Life, Enjoyment, and Satisfaction Questionnaire) - First and Last Visit (Week 0 and Week 17) [ Time Frame: Week 0 to 17 ]

    Quality of life, such that lower score reflects poorer quality of life

    Minimum score: 16 Maximum score: 80

  • Clinical Global Impressions Scale at Week 3 and Week 17 [ Time Frame: Week 3 to 17 ]

    Global severity of illness, such that a higher score reflects worse global severity

    Minimum score: 2 Maximum score: 14

Other Name: Cymbalta

Detailed Description:

Obsessive compulsive disorder affects approximately 3% of the population. Treatment options include the selective serotonin reuptake inhibitors (SSRIs), dual serotonin and norepinephrine reuptake inhibitors (SNRIs), and behavioral therapy. Duloxetine is a new SNRI. This study aims to assess the efficacy of duloxetine for the treatment of OCD.

Before subjects give written informed consent, they are made aware of alternatives to participation in this study, which can include independently seeking pharmacotherapy or cognitive behavioral treatment for OCD. Patients will then begin open-label treatment with duloxetine at 30 mg/day and will be seen again in one week (Visit 2). At Visit 2, patients will be assessed and, if they are not experiencing any significant side effects, the dose will be increased to 60 mg/day. Patients who are experiencing significant side effects at 30 mg/day will be discontinued from the study and offered standard treatment in our clinic. Patients taking 60 mg/day will then return for assessment in four weeks (Visit 3). At this time, if they are not experiencing any significant side effects, the dose will then be increased to 120 mg/day. Patients who are unable to tolerate 120 mg/day will have their dose decreased back down to 60 mg/day and will continue the trial. End of study final statistical analyses will be conducted both including and excluding these patients. Remaining assessments will be every 4 weeks (Visits 4, 5, 6). Thus, in total this is a 17-week study with 12 weeks at the high dose believed to be necessary for response.

At each visit following the initial visit, patients will be assessed using the Y-BOCS, BDI, BAI, and CGI. The Q-LES-Q will only be administered at the initial and last visit.

The study procedure is similar to standard medical treatment for OCD at MGH. Like standard care, participants start on the lowest dose of the medication and then increase that dose to the maximally tolerated level. Barring any significant side effects, the patient remains on that dose for 4-8 weeks to provide the medication with an adequate trial period. At the end of that period, efficacy would be assessed and other alternatives would be discussed.

One difference between the study and standard care is that the study will provide more assessment through verbal and written scales. This additional assessment could greatly benefit the patient as they decide between other treatment options. Another difference is that participants cannot be involved in current behavior therapy throughout the study. Many patients choose to pursue medical treatment without behavior therapy in standard care; however, in standard care, they have the option of pursuing both concurrently or pursuing just behavior therapy. If a patient wishes to pursue just behavior therapy or receive medication and therapy concurrently, then other forms of treatment at MGH might be more appropriate. If they only want medical treatment, the study is similar to standard care at a lower cost.


Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of OCD by DSM-IV
  • Age 18-65
  • Y-BOCS greater than 20
  • Written informed consent
  • Females of childbearing potential must have a negative serum or urinary beta-HCG test.

Exclusion Criteria:

  • Pregnant women or women of childbearing potential who are not using a medically accepted means of contraception.
  • Patients who, in the investigator's judgment, pose a serious suicidal or homicidal risk.
  • Serious or unstable medical illness including cardiovascular (including hypertension), hepatic, renal, respiratory, endocrine, neurologic, or hematologic disease. Patients on anticoagulant therapy.
  • History of seizure disorder
  • Comorbid bipolar disorder, psychosis, organic mental disorder, or developmental disorder
  • If there is a history of substance abuse, patients in remission at least 6 months.
  • Currently being treated with behavioral therapy, specifically exposure and response prevention, for OCD.
  • Other medications for medical disorders that may interfere with duloxetine
  • Current major depression or prescribed an antidepressant for major depression within the past 12 months. We will assess depressive symptoms with the BDI throughout the course of the study in order to assess subsyndromal depressive symptoms and to assess for the emergence of depressive symptoms.
  • Taken other psychotropic medication within 2 weeks of beginning the study (4 weeks for fluoxetine).
  • More than 1 adequate trial (at least 10 weeks at maximally tolerated dose) with another SSRI in the past.
  • Known hypersensitivity to duloxetine or any of the inactive ingredients.
  • Treatment with a monoamine oxidase inhibitor (MAOI) within 14 days of randomization or potential need to use an MAOI drug during the study or within 5 days of discontinuation of study drug.
  • Patients with uncontrolled narrow-angle glaucoma.
