Official title
31P-MRS and Resting State Functional Connectivity Analysis of the Effects of 5-hydroxytryptophan and Creatine for Antidepressant Augmentation in Patients With SSRI/SNRI-resistant Major Depressive Disorder
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a three-armed clinical trial examining the effect of 5-hydroxytryptophan and creatine monohydrate as augmenting agents for the treatment of depression. Subjects will be randomized between 5-HTP + placebo, creatine + placebo, and 5-HTP + creatine, for 8 weeks. The ability of the interventions to affect biomarkers associated with depression will be assessed using brain phosphorus magnetic resonance spectroscopy, functional connectivity imaging, and plasma serotonin levels.
