- •Subject meets the criteria of fatigue per the 1994 CDC Case Definition for Chronic Fatigue Syndrome (CFS): Unexplained persistent or relapsing chronic fatigue that is of new or definite onset (i.e., not lifelong), is not the result of ongoing exertion, is not substantially alleviated by rest, and results in substantial reduction in previous levels of occupational, educational, social, or personal activities. The fatigue must have persisted or recurred during 3 or more consecutive months of illness and must not have preceded the onset of the COVID-19 symptoms.

- •Current symptoms of coronary insufficiency (i.e. - angina pectoris and/or ST segment depression on EKG).
- •Evidence of uncontrolled atrial or frequent or complex ventricular ectopy, or myocardial conduction defect which would increase the risk of syncope (for example, second degree or higher A-V block).
- •Subject (or legally authorized representative) provides written informed consent prior to initiation of any study procedures.
- •Men and women of childbearing potential and their partner must agree to use two medically accepted methods of contraception (e.g., barrier contraceptives [male condom, female condom, or diaphragm with a spermicidal gel], hormonal contraceptives [implants, injectables, combination oral contraceptives, transdermal patches, or contraceptive rings], or one of the following methods of birth control (intrauterine devices, bilateral tubal occlusion, or vasectomy) or must practice complete sexual abstinence for the duration of the study (excluding women who are not of childbearing potential and men who have been sterilized).
- •Females of child-bearing potential must have a negative urine pregnancy test at Screening Visit and prior to receiving the first dose of study drug; and Male participants must agree to use contraception and refrain from donating sperm for at least 90 days after the last dose of study intervention.
- •Subject is willing and able to comply with scheduled visits, drug administration plan, laboratory tests, other study procedures and study restrictions.
排除标准

- •History of splenectomy.
- •Known hypercoagulable state or at increased risk of thrombosis (e.g., due to immobility)
- •Liver cirrhosis or patient showing signs of clinical jaundice at the time of screening.
- •Transaminase (ALT or AST) >3X ULN or total bilirubin >2X ULN at screening
- •Chronic kidney disease stage 4 or requiring dialysis at the time of screening.
- •Estimated GFR <60 mL/min/1.73 m2 at the time of screening
- •NYHA Class III or IV congestive heart failure (CHF).
- •Exhibiting signs of uncontrolled hypo-or hyper-thyroidism at the time of Screening.
- •Diagnosis of autoimmune disease (e.g., SLE, rheumatoid arthritis, psoriasis) at the time of screening
- •Uncontrolled rheumatologic disorders at the time of screening.
- •Diagnosis of sleep apnea (central or obstructive) at the time of screening.
- •History of organ transplantation or are candidates for organ transplantation at the time of screening.
- •History of Chronic Fatigue Syndrome prior to COVID-19 infection.
- •History of fibromyalgia prior to COVID-19 infection.
- •History of major psychiatric disorder including psychotic or melancholic features, bipolar disorders, schizophrenia of any subtype, schizoaffective disorder, major depression delusional disorders of any subtype, dementias of any subtype, anorexia nervosa or bulimia nervosa.
- •Any malignancy within the past 5 years, excluding successfully treated basal cell carcinoma or squamous cell carcinoma without evidence of metastases.
- •Any other clinically significant serious systemic diseases, chronic or intercurrent active medical disorder and other reasons which would interfere with study conduct or study results interpretation per the Investigator.
- •Chronic or intercurrent acute medical disorder or disease making implementation or interpretation of the protocol or results difficult or unsafe per the investigator.
- •Therapy with interferons, interleukins, or other cytokines or investigational drugs within 6 weeks of beginning study medication. Subjects must give written informed consent prior to discontinuation of investigational drugs.
- •Treatment with any of the following therapies within the eight (8) weeks immediately preceding the start of study baseline or during baseline: systemic glucocorticoids (i.e., hydrocortisone, prednisone, etc.) or mineralocorticoids (i.e., fludrocortisone (Florinef), etc.), interferons, interleukin-2, systemic antivirals, gamma globulin or investigational drugs or experimental agents not yet approved for use in the United States.
- •Prior participation in an Ampligen® study.
- •Medical necessity, as determined by the patient's primary doctor or the principal investigator, to continue aspirin (ASA) or non-steroidal anti-inflammatory (NSAID) drugs for 20 consecutive days or for more than 10% of the study duration.

- •Pregnant or breast feeding.
- •Participation in another study for an investigational treatment.

结局指标
主要结局
Change From Baseline to Week 13 in PROMIS Fatigue Score (T-Score)
时间窗: Baseline and Week 13
Change in mean fatigue T-score as measured by PROMIS® (Patient-Reported Outcomes Measurement Information System) Fatigue short form 7a that assess a range of self-reported symptoms, from mild subjective feelings of tiredness to extreme exhaustion. The lowest possible raw score is 7; the highest possible raw score is 35. Raw summed scores are converted to T-score values that are standardized such that 50 represents the average (mean) for the US general population, with a standard deviation of 10 points. The lowest possible T-score is 29.4; the highest possible T-score is 83.2. A higher T-score represents more of the concept being measured, meaning the higher the T-Score, the worse the fatigue of the individual. Scores \<55 are within normal limits, 55-60 mild, 61-70 moderate, and \>70 severe fatigue.
次要结局
- Change From Baseline to Week 6 in PROMIS Fatigue Score (T-Score)(Baseline to Week 6)
- Change From Baseline to Week 13 in PROMIS Fatigue Score (T-Score), Excluding Response to Item Seven(Baseline to Week 6 and 13)
- Change From Baseline to Week 6 and Week 13 in Distance Traveled During 6-minute Walk Test (6MWT)(Baseline to week 6 and week 13)
- Percentage of Subjects With Minimal Clinically Important Difference (MCID)(End of 12 week treatment phase)
- Change From Baseline to Week 6 and 13 in PROMIS Cognitive Function Converted Score (T-Score).(Baseline to Week 6 and 13)
- Change From Baseline to Week 6 and 13 in PROMIS Sleep Disturbance Score (T-Score)(Baseline to Week 6 and 13)
