The purpose of this study is to determine whether creatine will be helpful as an adjunctive treatment for treatment-resistant major depressive disorder (MDD) in female and male Veterans. We hypothesize that Veterans receiving creatine will show decreased depressive symptoms as measured by the Montgomery-Asberg Depression Rating Scale (MADRS). We will also use 31-Phosphorus Magnetic Resonance Spectroscopy (31-P MRS) brain scans to compare levels of neurochemicals related to energy metabolism in the brain, before-and-after treatment with creatine, and between healthy controls and MDD participants.

Further study details as provided by University of Utah:

Primary Outcome Measures:
  • Change in Montgomery-Asberg Depression Rating Scale (MADRS) Score [ Time Frame: screening; baseline; weeks 1, 2, 4, 5, 8, and 10 ] [ Designated as safety issue: No ]
    The primary clinical outcome measure will be the change in MADRS; response will be defined as a 50% or greater decrease in MADRS score from baseline and a Clinical Global Impression Scale (CGI) improvement score of 1 or 2

Secondary Outcome Measures:
  • Changes in 3T 31Phosphorus Magnetic Resonance Spectroscopy metabolites [ Time Frame: Baseline and 8 weeks ] [ Designated as safety issue: No ]
    The primary neuroimaging outcome measures will be changes in 3T 31P-MRS metabolites (PCr and β-NTP) globally and in the anterior cingulate cortex

Estimated Enrollment: 40

Study Completion Date: April 2014
Primary Completion Date: April 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Healthy Control
20 adult male veterans free from psychiatric disorders or uncontrolled medical illnesses will be recruited as healthy controls. They will not receive creatine treatment.
Experimental: Creatine
20 adult male veterans with SSRI-resistant major depression will be treated with Creatine 5 grams per day for eight weeks.
Drug: Creatine
Creatine will be given at a dose of 5 grams per day to adult male veterans with SSRI-resistant depression for eight weeks. Creatine is dispensed as a powder.
Other Name: Creapure

  • Inability to give informed consent
  • Any medications which are likely to affect the results of MRS imaging as determined by the PI
  • Contraindication to MRI (e.g., pacemaker, ferromagnetic implants in the body, claustrophobia)
