NCT06263660

Brief Summary

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. Participants will be randomized with a 1-1 ratio to receive the keto-like supplement (n= 30 completers) or placebo (n=30 completers) taken orally three times per day for 8 weeks. Participants will undergo a 10.5-hour screening/baseline evaluation visit split over 2 days at week 0 including questionnaires, neuroimaging before and after supplement or placebo administration and blood draws, office visits at week 2 (1.5 hours), week 4 (3 hours), week 6 (0.5 hours), week 8 (6 hours), a follow-up visit at week 10 (1.5 hours) and two phone calls between visits (weeks 1 and 3) during which a brief clinical assessment will be obtained (10 minutes each). The total time involved in the study is approximately 23.5 hours.

  • Medically stable based on clinical laboratory tests, medical history and vital signs
  • No intention to become pregnant during the study
  • A woman of childbearing potential must have a negative serum pregnancy test at screening
  • Consent that possible random finding is reported (e.g. brain abnormality during imaging)

You may not qualify if:

  • Has a current or recent history of clinically significant suicidality
  • Has a history of moderate or severe substance or alcohol use disorder according to DSM-5 criteria, except nicotine or caffeine, within 12 months before screening

  • Change in medication dose and/or frequency within the last 6 weeks. Participants must be on stable medications for 6 weeks prior to enrollment.
  • Plans to change medication dose/frequency during the course of the study. Must plan to remain on stable dose for the duration of the study, unless otherwise indicated by their provider during the course of the study.

  • Has received an investigational drug/vaccines, used an invasive investigational medical device within 60 days before the planned first dose of the keto-like supplement or has participated in 2 or more interventional clinical studies in the previous 1 year, or is currently enrolled in any drug or non-drug interventional study.
  • Has had major surgery, (i.e. requiring general anesthesia) within 12 weeks before screening, or will not have fully recovered from surgery, or has surgery planned during the time they are expected to participate in the study.
  • Intake of Omega 3 fatty acids (DHA, EPA, fish oil supplements)
  • Significant cognitive impairment, clinically relevant or progressive disease (e.g., liver, kidney, cardiovascular system, respiratory tract, vascular system, brain, metabolism, thyroid) that could affect the course of the study
