  Purpose

Background/Rationale: Cognitive problems are a common symptom in individuals with Multiple Sclerosis (MS). Treatment options are limited, and there is a pressing need for new interventions to treat MS-related cognitive impairment. Glucose (a type of sugar) is used to fuel the cells of the healthy brain. For people with neurological conditions such as MS, glucose is not converted into energy as efficiently as it would be in a healthy brain, which can lead to a decrease in cognitive function. Caprylic Triglyceride may work to bypass this problem by providing an alternative energy source that is metabolized in the liver and used by the brain.

Objective: To evaluate the therapeutic effects of 90 days of caprylic triglyceride on cognitive impairment in multiple sclerosis.

Design: Randomized, double blinded, placebo controlled trial of 158 subjects.

Outcome: Change in Total Learning (Trials 1-5) on the California Verbal Learning Test-2nd Edition-(CVLT-II) AND Change in Symbol Digit Modalities Test (SDMT) (at day 90


Condition Intervention
Relapsing Remitting MS Secondary Progressive MS Primary Progressive MS Dietary Supplement: Caprylic Triglyceride Dietary Supplement: Placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized Double-Blind Placebo-Controlled Study of Caprylic Triglyceride for Cognitive Impairment in Subjects With Multiple Sclerosis.

Primary Outcome Measures:
  • Change in Total Learning (Trials 1-5) on the California Verbal Learning Test-2nd Edition (CVLT-II) (range from 0 to 80) [ Time Frame: Baseline and 90 days ]
    measure of verbal learning and memory

  • Change in Symbol Digit Modalities Test (SDMT) (range from 0-110) [ Time Frame: Baseline and 90 days ]
    measure of processing speed and attention

  • Number of participants reporting adverse events [ Time Frame: Baseline and 90 days ]
    The number of participants experiencing adverse events in the active treatment and placebo group will be examined.


Secondary Outcome Measures:
  • Change in EDSS [ Time Frame: Baseline and 90 days ]
    measure of disease severity

  • Change in Beck Depression Inventory -2nd edition (BDI-II) [ Time Frame: Baseline and 90 days ]
    Self-report depression scale

  • Change in Multiple Sclerosis Quality of Life Inventory (MSQOL-54) [ Time Frame: Baseline and 90 days ]
    Quality of life inventory

  • Change in Modified Fatigue Impact Scale (MFIS) [ Time Frame: Baseline and 90 days ]
    Self-report Fatigue scale


Estimated Enrollment: 158

Arms Assigned Interventions
Experimental: Caprylic Triglyceride
Caprylic Triglyceride (40 gram packet orally once a day for 90 days)
Dietary Supplement: Caprylic Triglyceride
Caprylic Triglyceride is a medical food that is used for the dietary management of the metabolic processes associated with mild to moderate Alzheimer's disease.
Other Name: Axona
Placebo Comparator: Placebo
Placebo (40 gram packet orally once a day for 90 days)
Dietary Supplement: Placebo
Placebo (40 gram packet orally once a day for 90 days)

Detailed Description:

Patients with all types of MS (Relapsing Remitting, Secondary Progressive, or Primary Progressive) are eligible to participate. Participants will undergo detailed cognitive assessment before initiating treatment and again after 90 days of treatment, to determine whether Caprylic Triglyceride demonstrates a benefit over placebo.

Dosage: 40 gram packet orally once a day Duration of Treatment: 90 days

Analyses: Interim analyses will be conducted after 72 subjects have completed the trial and objective STOP criteria for efficacy and futility have been defined in the protocol. Final analyses will be an intent-to-treat (ITT) analysis to evaluate each of the primary aims.
