Ketogen diett og nevromodulering ved behandlingsresistent depresjon (ALIGN)

4. august 2026 oppdatert av: Dr. Sean Michael Nestor, Sunnybrook Health Sciences Centre

Adjuvant lavkarbo ketogen diett for å forbedre bildeveiledet nevromodulasjon ved behandlingsresistent depresjon

Målet med denne kliniske studien er å teste om kombinasjonen av en ketogen diett (KD) med personlig tilpasset, akselerert intermitterende theta burst-stimulering (iTBS) gir større reduksjon i depressive symptomer enn iTBS kombinert med en standard sunn diett hos voksne med behandlingsresistent depresjon. Studien har også som mål å avgjøre om deltakerne kan følge en ketogen diett gjennomførbart under en akselerert iTBS-behandlingsperiode og om dietten gir målbare endringer i ketonnivåer.

Spesifikt har studien som mål å avgjøre om den kombinerte intervensjonen:

  1. Reduserer depressive symptomer
  2. Øker sirkulerende ketonnivåer
  3. Er gjennomførbar og tolerabel under akselerert iTBS-behandling

Deltakerne vil starte enten en KD eller en diett i tråd med Canadas matveileder (CFGD) med en 3-ukers innføringsperiode for dietten, deretter vil de gjennomgå en periode med personlig tilpasset, akselerert iTBS mens de fortsetter den tildelte dietten. Før og etter iTBS-behandlingsperioden vil deltakerne fullføre kliniske vurderinger, gi blodprøver for metabolsk testing og gjennomgå MR-undersøkelser for å vurdere hjernekoblinger. Ketonnivåer vil bli målt daglig gjennom hele den 15-ukers die​ttintervensjonen. Innenfor-gruppe- og mellom-gruppe-forskjeller vil bli sammenlignet for å karakterisere endringer i kliniske utfall, metabolisme og hjernefunksjon.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Ketogenic Diet
Participants in this arm will follow a well-formulated ketogenic diet (low carbohydrate, moderate protein, high fat) for a 3-week dietary lead-in period prior to neuromodulation, and will continue the diet for a total of 12 weeks. The diet is designed to achieve and maintain nutritional ketosis (blood ketone levels of 0.5 to 3 mmol/L). Dietitian support will be provided through scheduled counseling and ongoing monitoring of finger-stick ketone and glucose testing.
Enhet: Accelerated Intermittent Theta Burst Stimulation (iTBS)
Intermittent theta burst stimulation (iTBS), a form of repetitive transcranial magnetic stimulation (rTMS), is a non-invasive brain stimulation technique approved by the FDA and Health Canada for the treatment of TRD. In this study, participants will receive an accelerated course of imaging-guided, neuronavigated left dorsolateral prefrontal cortex (DLPFC) iTBS targeted based on functional connectivity with the subgenual anterior cingulate cortex (sgACC). Stimulation protocol consists of 1800 pulses per session, delivered at 110% of resting motor threshold, with 50-minute inter-session intervals, for 8 sessions per day over 5 consecutive days.

Atferdsmessig: Ketogenic Diet
A well-formulated ketogenic diet consisting of low carbohydrate, moderate protein, and high fat intake, designed to achieve and maintain nutritional ketosis (blood ketone levels of 0.5 to 3 mmol/L). Delivered with dietitian-led counseling and monitored via finger-stick ketone and glucose testing.
Aktiv komparator: Canadian Food Guide-Aligned Diet
Participants in this arm will follow a Canadian Food Guide-aligned diet for a 3-week dietary lead-in period prior to neuromodulation and will continue the diet for a total of 12 weeks. The diet will emphasize balanced intake of vegetables, fruits, whole grains, and protein foods, without specific macronutrient restrictions. Dietitian counseling will be approximately matched in frequency and duration to the ketogenic diet arm. Nutritional monitoring will include dietary logs and metabolic assessments without targeted induction of ketosis. Participants will perform finger-stick glucose testing.

Plan for individuelle deltakerdata (IPD)

Planlegger du å dele individuelle deltakerdata (IPD)?

JA

IPD-planbeskrivelse

Deidentifiserte individuelle deltakerdata (IPD) og relevant støttedokumentasjon (inkludert studieprotokollen, statistisk analyseplan og datatordbok) vil bli delt for å muliggjøre sekundærforskning. Data vil bli delt med kvalifiserte forskere for vitenskapelig forsvarlige analyser, underlagt godkjenning og signering av en dataavtale i henhold til Sunnybrook Research Institutes retningslinjer. Forespørsler om tilgang vil bli vurdert for å sikre vitenskapelig verdi, gjennomførbarhet og beskyttelse av deltakernes konfidensialitet.

IPD-delingstidsramme

Studieprotokollen og informert samtykkeskjema vil bli publisert før studieoppstart. Studieresultater vil bli formidlet så snart som mulig etter studieavslutning. Anonymiserte individuelle pasientdata vil være tilgjengelige fra 12 måneder etter publisering av primærresultatene (eller 12 måneder etter studieavslutning dersom ingen publisering finner sted).

Tilgangskriterier for IPD-deling

Delt data vil inkludere avidentifisert IPD og støttedokumenter (studieprotokoll, statistisk analyseplan og databok).

Tilgang vil være begrenset til forskere med passende institusjonell tilknytning og dokumentert etisk godkjenning, som sender inn et metodisk fornuftig forslag. Forespørsler vil bli vurdert av studiens hovedansvarlige forsker (eller utpekt datatilgangskomité).

Godkjente brukere vil få tilgang gjennom sikre, institusjonelt godkjente datadelingssystemer. Alle brukere må signere en dataavtale som forbyr re-identifisering, videre deling og enhver bruk utenfor det godkjente forslaget.
