Primary Outcome Measures

Name	Time	Method
EuroQol 5-Dimension 5-Level (EQ-5D-5L) Visual Analogue Scale	at Screening, Day 60, Day 90, and Day 180	The EQ-5D-5L is a standardized measure of health status that consists of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) each with 5 levels of severity, and a visual analogue scale (VAS) where individuals rate their overall health from 0 (worst imaginable health) to 100 (best imaginable health).

Secondary Outcome Measures

Name	Time	Method
The EuroQol Five-Dimensional Health Questionnaire (EQ-5D-5L)	at Screening, Day 60, Day 90, and Day 180	The EQ-5D-5L is a validated, standardized, generic instrument that is a preference-based health- related quality of life questionnaire. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate their health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. Full scale from 5 to 25, with higher score indicating poorer health outcomes.
Patient-Reported Outcomes Measurement Information System 29 (PROMIS-29)	at Screening, Day 60, Day 90, and Day 180	The PROMIS-29 v2.0 profile assesses pain intensity using a single 0-10 numeric rating item and seven health domains (physical function, fatigue, pain interference, depressive symptoms, anxiety, ability to participate in social roles and activities, and sleep disturbance) using four items per domain. The values of all item responses are averaged to generate subscores for each dimension. From these subscores, a global physical health score and a global mental health score are generated. The scores are translated into T-scores according to a reference population with a mean of 50 and a standard deviation of 10.
General Symptom Questionnaire (GSQ-30)	at Screening, Day 60, Day 90, and Day 180	The General Symptom Questionnaire-30 (GSQ-30) is a valid and reliable instrument to assess symptom burden among patients with acute and post-treatment. The GSQ-30 total score ranges from 0 to 120, with higher scores indicating a greater symptom burden.
Fatigue Visual Analogue Scale (F-VAS)	at Screening, Day 60, Day 90, and Day 180	The F-VAS consists of 18 items related to fatigue and energy in a visual analogue scale from 0 to 100. A higher score indicates more fatigue.
DePaul Post-Exertional Malaise Questionnaire (DSQ)	at Screening, Day 60, Day 90, and Day 180	The DSQ is designed to evaluate 54 classic ME/CFS symptoms, including fatigue, post-exertional malaise, sleep, pain, neurological/cognitive impairments, and autonomic, neuroendocrine, and immune symptoms. Each symptom's frequency and intensity are rated on a 5-point scale (0-4). Frequency and severity scores are multiplied by 25, added together, and then divided by 2 to create a composite frequency/severity score for each symptom. These scores range from 0 to 100, with higher scores indicating a greater symptom burden.
Composite Autonomic Symptom Score 31(COMPASS-31)	at Screening, Day 60, Day 90, and Day 180	The COMPASS-31 is a 31-question self-assessment instrument of autonomic symptoms and function that is up-to-date, broadly applicable, easy to administer in a short amount of time, and based on a scientific approach. The total score ranges from 0 to 100, with higher scores indicating greater autonomic dysfunction.
Patient Health Questionnaire (PHQ-9)	at Screening, Day 60, Day 90, and Day 180	The PHQ-9 is a series of questions assessing presence and severity of depression symptoms. It evaluates each of the DSM-IV depression criteria and scores the responses from 0 ("Not at all") to 3 ("Nearly every day"). PHQ-9 scores of 5, 10, 15, and 20 represented mild, moderate, moderately severe, and severe depression, respectively. Full scale from 0-27, with higher score indicating more severe symptoms.
Generalized Anxiety Disorder (GAD-7)	at Screening, Day 60, Day 90, and Day 180	The GAD-7 is a 7-item scale developed and validated to identify generalized anxiety disorder and its severity. It assesses the frequency of 7 anxiety symptoms and scores the responses from 0 ("Not at all") to 3 ("Nearly every day"). Total scores of 5, 10, and 15 correspond to mild, moderate, and severe generalized anxiety disorder, respectively. Full scale from 0-21, with higher score indicating more symptoms.
Neuro-QoL™ v2.0 Cognitive Function-Short Form	at Screening, Day 60, Day 90, and Day 180	The Neuro-QoL Cognitive Function v2.0 short form assesses perceived difficulties in cognitive abilities, including memory, attention, decision making, planning, organizing, calculating, remembering, and learning. The short form consists of 8 questions assessed on a 5-point Likert scale, resulting in a raw score range of 8 to 40. A raw score is then converted to a T-score using conversion tables. Scores 0.5 - 1.0 SD worse than the mean (T-score 40-45) = mild symptoms/impairment. Scores 1.0 - 2.0 SD worse than the mean (T-score 30-40) = moderate symptoms/impairment. Scores 2.0 SD or more worse than the mean (T-score below 30) = severe symptoms/impairment.
Single-item Sleep Quality Scale (SQS)	at Screening, Day 60, Day 90, and Day 180	The SQS is a visual analog scale that instructs respondents to rate their overall quality of sleep over a 7-day recall period from 0 to 10. Scores of 0, 1, 4, 7, and 10 correspond to terrible, poor, fair, good, and excellent, respectively. Higher scores indicate better sleep quality.
Fatigue Severity Scale (FSS)	at Screening, Day 60, Day 90, and Day 180	The Fatigue Severity Scale (FSS) uses a 7-point scale (1-7) to assess fatigue, with higher scores indicating greater severity, and a total score ranging from 9 to 63. Higher scores indicate more severe fatigue.
Pain Visual Analogue Scale (P-VAS)	at Screening, Day 60, Day 90, and Day 180	Using a visual analogue scale, patients mark a point on a line representing a continuum from "no pain" to "worst pain," with scores ranging from 0 to 100, where higher scores indicate greater pain.
