New treatment option for Depression
Official title Evaluation of a Keto-Like Supplement on Brain Responses to Emotional Stimuli in Depression
ClinicalTrials.gov ID: NCT06263660
What this study is testing
- What it's testing
- This study aims to determine whether a keto-like supplement relative to placebo results in functional brain changes during fMRI tasks evaluating positive and negative valence in individuals with moderate to severe depression. In this double-blind randomized placebo-controlled trial, 75 individuals with a Patient Health Questionnaire (PHQ-9) scale score ≥ 10 (MDD) will be enrolled to participate in an 8-week treatment study to obtain 60 completers.
- Phase 2: a mid-size study of how well it works
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
