SECONDARY outcome

Timeframe: Baseline, Month 3, Month 6 and Every 26 weeks for up to 160 weeks

Population: All participants for whom EQ-5D-5L was measured. Trial was terminated early.

EuroQol 5 dimensions 5 levels (EQ-5D-5L) by visit. Count of participants per arm, or severity level of dimension. Measures 5 dimensions: mobility, self-care, usual activities, pain/discomfort, anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. Score ranges from 5-25 with lower score=better outcome, and higher score means a worse outcome.

SECONDARY outcome

Timeframe: Baseline, Month 3, Month 6 and Every 26 weeks for up to 160 weeks

Population: All participants for whom EQ VAS was measured. Trial was terminated early.

Euroquol Visual Analog Scale (EQ VAS): A patient-reported measure. The visual scale is numbered from 0 to 100, participants are directed as follows: "100 means the best health you can imagine, 0 means the worst health you can imagine. Mark an X on the scale to indicate how your health is TODAY." Higher scores mean better outcome, lower scores mean worse outcome.

Timeframe: Baseline, Month 3, Month 6 and Every 26 weeks for up to 160 weeks

Population: All participants for whom Neuro-Qol Fatigue was measured. Trial was terminated early.

Change from baseline in NeuroQOL Fatigue Questionnaire by visit. Questionnaire is comprised of 8 questions measuring participants incidence of fatigue affecting activities of daily living. Participants respond by choosing one of the following: 1=never, 2=rarely, 3=sometimes, 4=often, 5=always, with a lower score meaning a better outcome with fatigue affecting participant less, and high score meaning a worse outcome, with fatigue affecting the participant more. Total raw scores range from 8-40. Scores were converted to percentages: range0-100%. Change from baseline score: negative number means improved from baseline, positive number means worsened compared to baseline.

SECONDARY outcome

Timeframe: Baseline, Month 3, Month 6 and Every 26 weeks for up to 160 weeks

Population: All individuals for whom Work Limitations was measured. Trial was terminated early.

Work Limitations Questionnaire by visit. Comprised of 25 items, in 4 categories, or demands: Mental/Interpersonal, Output Tasks, Physical Tasks, and Time Management, measuring the degree to which employed individuals are experiencing limitations on-the-job due to their health problems, and health-related productivity loss. 1= All of the time (100%), 2= most of the time, 3=some of the time (about 50%), 4=slight bit of time, 5=none of the time (0%), 6=does not apply to my job. (Presenteeism). The WLQ items ask respondents to rate their level of difficulty or ability to perform specific job demands. Scale score range from 0 (limited none of the time=better outcome) to 100 (limited all of the time= worse outcome) and represent the reported amount of time in the prior two weeks respondents were limited on-the-job.

SECONDARY outcome

Timeframe: Baseline, Month 3, Month 6 and Every 26 weeks for up to 160 weeks

Population: All participants for whom PhGA was measured. Trial was terminated early.

Physician Global Assessment- Mean Score by visit. PGA Scale asks physician to rate participant's current health status as follows: 1=Excellent, 2=Very good, 3=Good, 4=Fair, and 5=Poor. Total score ranges from 1-5. Higher score means lower health status, worse outcome; lower score means better health status, better outcome.

SECONDARY outcome

Timeframe: Baseline, Week 13, 26, 52, 104, 156, End of Study (Week 160)

Population: All participants for which PMMSA was measured. Trial was terminated early.

The PMMSA is a patient-reported outcome measure, assessing a participant's "worst feeling" of 10 symptoms during the last 24 hours: tiredness at rest, tiredness during activities, muscle weakness at rest, muscle weakness during activities, balance, vision, abdominal discomfort, muscle pain, numbness, and headache using a 4-point scale: 1=Not at all, 2=Mild, 3=Moderate, and 4=Severe. Max Score =40= worse outcome, Min score= 10= better outcome on scale. PMMSA Individual Items shows number or participants with mild, moderate, severe or no symptoms at all.

SECONDARY outcome

Timeframe: Baseline, Month 3, Month 6 and Every 26 weeks for up to 160 weeks

Population: All participants for whom PMMSA was measured. Study terminated early.

Change from baseline in the Total Fatigue score Primary Mitochondrial Myopathy Symptom Assessment (PMMSA) where participants report their "worst feeling" of 4 symptoms: Tiredness at rest, Tiredness during activities, Muscle weakness at rest, Muscle weakness during activities, at the end of each treatment period. Total fatigue score is sum of Q1 to Q4 only of PMMSA) and is scored as follows: 1=Not at all, 2=Mild, 3=Moderate, and 4=Severe. Total score range is 4-16; lower score means less fatigue and better outcome, higher score means more fatigue and worse outcome. Raw scores were transformed into percentages: 0-100%. Change from baseline: the lower the score, the better the outcome,=less fatigue; the higher the score, means worse outcome= more fatigue.
