Fatigue is one of the most prevalent and disabling symptoms of multiple sclerosis. Current treatments, including pharmacological, physical therapy, sleep regulation and psychological interventions are of marginal benefit. Pharmacological treatments have inconsistent evidence. Recent studies show that non-deceptive open-label placebos (OLP) have moderate-to-large effects on symptoms, including fatigue, in adults with a variety of medical conditions. Hence, this is a pilot and feasibility study to obtain data on the feasibility and effects of OLP for multiple sclerosis related fatigue and its impact to provide the basis for a competitive NIH application. This pilot study will be the first study to evaluate whether OLP, that garners full consent and engages patients in their wellness, may offer a safe, effective treatment for multiple sclerosis related fatigue.
The purpose of this pilot study is to evaluate the feasibility of recruiting, enrolling and retaining participants in a study on the acceptability and effects of a non-deceptive (open-label) administration of placebo pills for treating MS related fatigue. Specific Aim 1 will assess the feasibility endpoints including accrual (enroll 44 participants), retention (80% of the sample) and placebo adherence (90%). Specific Aim 2 will evaluate the between-group changes in fatigue, quality of life, cognitive functioning and self-efficacy. Specific Aim 3 will evaluate participant acceptability, satisfaction and experience. Design: This pilot study is a randomized control trial consisting of three arms: open label placebo arm, expectancy arm, and usual care arm. The clinical coordinator will review medical records, enroll and consent participants based on the following inclusion criteria: diagnosis of MS, 19 years or older, report of moderate to severe fatigue, PDDS score of \< 7, and stable dose of DMTs for 90 days. Exclusion criteria consists of: major comorbid conditions and use of off label medications or exercise programs in the past 30 days, and if one is confined to a wheelchair. Baseline and 21 day tele assessments will involve objective measures performed by a physical therapist, Single Digit Modality Test (SDMT) and Five Time Sit to Stand (FTSST) and subjective questionnaires sent to participant's email including Modified Fatigue Impact Scale (MFIS), Functional Systems Score (FSS), Patient Reported Outcomes Measurement Information System (PROMIS), Perceived Deficits Questionnaire, Epworth Sleepiness Scale, and the SF-36 assess of quality of life. Participants will be randomized by the clinical coordinator after baseline testing. The open label placebo and expectancy arm will meet with the care provider who will follow a scripted orientation that mimics a typical patient-provider interaction when prescribing a medication, including the rationale for effectiveness. The provider will emphasize the importance of adherence to the medication for the open label placebo arm and the breathing exercises for the expectancy arm for the next 21 days. A tracking sheet will be provided to both arms to document adherence. The usual care arm will meet with the care provider who will follow a scripted orientation on fatigue and heat management strategies. All participants will receive educational materials on fatigue and heat management. A day 11 check in call will be made to gauge progress and answer questions. After the 21 day tele assessment is performed, the participant will complete subjective questionnaires via email for 28 day and 35 day follow up.

Change from baseline fatigue at 21 days using the Fatigue Severity Scale (FSS).
This scale is used to measure fatigue and the scale has a range from 9-63 with 9 being the best possible score and 63 being the worst score.
Time frame: Participants will complete this scale at baseline and 21 days later, the participant will spend 10 minutes each assessment completing this scale.
Change from baseline impact of fatigue at 21 days using the Modified Fatigue Impact Scale (MFIS).
This scale is used to measure fatigue and the scale has a range from 0 to 84 with 0 being the best possible score and 84 being the worst score.
Time frame: Participants will complete this scale at baseline and 21 days later, the participant will spend 15 minutes each assessment completing this scale.
Change from baseline quality of life at 21 days using the 36-item Short Form survey (SF-36).
The scores for this survey range from 0-100 with 0 being the worst possible score and 100 being the best possible score.
Time frame: Participants will complete this scale at baseline and 21 days later, the participant will spend 15 minutes each assessment completing this scale.
Change from baseline sleepiness at 21 days using the Epworth Sleepiness Scale (ESS).
This scale is used to measure sleepiness and the scale has a range from 0-24 with 0 being the best possible score and 24 being the worst.
Time frame: Participants will complete this scale at baseline and 21 days later, the participant will spend 15 minutes each assessment completing this scale.
Change from baseline neurological functioning at 21 days using the Perceived Deficit Questionnaire 5-Item Version (PDQ-5).
The scores for this questionnaire range from 5-25 with 5 being the best possible score and 25 being the worst possible score.
Time frame: Participants will complete this scale at baseline and 21 days later, the participant will spend 15 minutes each assessment completing this scale.
