Study summary

The goal of this clinical trial is to learn if the time an individual eats each day impacts neurological health in people with multiple sclerosis. The main questions the investigators are asking are:

  1. Does meal timing affect biomarkers of neuronal health (neurofilament light chain [NfL] and BDNF) and inflammation (IL-6, IL-17, TNF-ɑ) in adults with MS.
  2. Does meal timing affect expression of circadian clock genes and genes associated with autophagy in adults with MS.

Participants will be instructed to start and stop eating at specific times each day based on their group assignment and their personal schedule. They will respond to prompts sent to them on their smartphone to record the times they start and stop eating each day.

As a secondary goal, the study will also explore the feasibility of including translocator protein (TSPO)-PET imaging of neuroinflammation in future clinical trials of TRE in people with MS. To accomplish this, imaging will be completed in a subset of 8 participants at the beginning and end of the study.

Read the detailed description

The mechanisms underlying the relationship between diet and MS are not well understood. A leading theory is that diet affects disease progression and symptoms through modulation of neuroinflammation. Previous studies in participants with other conditions suggest that time restricted eating (TRE) may reduce inflammation by improving circadian rhythms. If this holds true in people with MS, it may explain how TRE improves clinical outcomes of cognitive and physical function as seen in a previous trial. It may also explain diurnal fluctuations in pain and fatigue experienced by people within MS.

Although a previous study measured the effect of TRE on physical and cognitive function, as well as pain and fatigue, it was a single arm study and did not measure the hypothesized mechanisms of action. Therefore, the purpose of this pilot study is to examine the effects of TRE on neurological, inflammatory, and circadian markers in adults with MS.

Adults with relapsing forms of MS (relapsing remitting [RRMS] or secondary progressive [SPMS], n = 22) will be randomly assigned to either a TRE group that will eat all food within an 8-hour window each day (treatment group) or a group that will eat over 12 or more hours each day for 12 weeks.

Further, investigators will assess the feasibility of using Positron Emission Tomography (PET) imaging to measure changes in neuroinflammation with TRE. This exploratory aim will be completed in a subset of participants (n=8), and will be used to finalize imaging protocols and determine feasibility of including translocator protein (TSPO)-PET imaging of neuroinflammation in future clinical trials of TRE in people with MS.

Exclusion criteria

Exclusion Criteria:

  • Relapse within previous 30 days
  • Actively engaged in a weight loss program or unwilling to follow assigned eating schedule
  • Current use of GLP-1 or use within previous 3 months
  • Regularly fasts > 12 hours/day
  • Employed in night shift or rotating shift work
  • Unable to walk 25 feet with or without assistive device (EDSS > 6.5).
  • Current use of insulin or sulfonylurea agents
  • Pregnant or breastfeeding
  • Currently enrolled in another trial that would confound results (e.g., exercise studies or other diet studies)
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Aug 2026 (actual). Primary completion is estimated for Sep 2027, 13 months after the start.

Of 847 non-industry interventional studies with no phase under Multiple Sclerosis, half reached primary completion within 22 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 43. This study's planned 13 months is below that.

Counting every sponsor, half of 869 studies reached it within 21 months; a quarter within 9 and three quarters within 43.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
