Dose-Ranging Trial of Creatine Augmentation for Adolescent Females With Treatment-Resistant Major Depressive Disorder

Completed · Early Phase 1 · Has a placebo group

Conditions studied: Major Depressive Disorder

In brief

The purpose of this study is to see if creatine, which is a naturally occurring chemical in the body, is effective for treating Major Depressive Disorder (MDD) in female teenagers. The primary hypothesis is that compared to placebo, 2g, 4g, and 10g of creatine monohydrate for eight weeks will be associated with a significant increase in brain phosphocreatine (PCr) concentrations.

• Participants may be enrolled in individual and/or group psychotherapy, if it has been ongoing for at least 8 weeks.
• Participants must have been in treatment with an SSRI for at least 8 weeks, the last 4 of which were at a dosage of > or equal to 20 mg per day of fluoxetine or its equivalent, e.g. 20 mg per day of paroxetine, 20 mg citalopram, 10 mg escitalopram, or 100 mg sertraline. If the participant attempted, but could not tolerate, a dose comparable to 20 mg fluoxetine, they will be considered eligible.
