Original description

This study is a prospective, randomized controlled, basket trial. Patients diagnosed with Post-Acute Sequelae of SARS-CoV-2 Infection who meet the inclusion and exclusion criteria are recruited and divided into three symptom clusters: Inflammatory Cardiac involvement symptoms cluster, cough symptoms cluster and fatigue symptoms cluster. Each symptom cluster is randomly divided into an experimental group and a control group, Patients who do not accept treatment can be included in the observational cohort. Subjects in the experimental group receive immunomodulatory interventions plus conventional treatment, while subjects in the control group receive conventional treatment only. Subjects in each symptom cluster undergo clinical medical record data collection, laboratory tests, and imaging examinations at specified time points, as well as records of adverse events.Read full original descriptionShow less

A Randomized Controlled Basket Study for Evaluating Immunomodulatory Interventions in Post-Acute Sequelae of SARS-CoV-2 InfEction (RISE)

This study is a prospective, randomized controlled, basket trial. Patients diagnosed with Post-Acute Sequelae of SARS-CoV-2 Infection who meet the inclusion and exclusion criteria are recruited and divided into three symptom clusters: Inflammatory Cardiac involvement symptoms cluster, cough symptoms cluster and fatigue symptoms cluster. Each symptom cluster is randomly divided into an experimental group and a control group, Patients who do not accept treatment can be included in the observational cohort. Subjects in the experimental group receive immunomodulatory interventions plus conventional treatment, while subjects in the control group receive conventional treatment only. Subjects in each symptom cluster undergo clinical medical record data collection, laboratory tests, and imaging examinations at specified time points, as well as records of adverse events.

Inclusion: 1. Age ≥18 years; 2. Post-infection with SARS-CoV-2 for more than 3 months and meets the World Health Organization (WHO) definition of Long COVID; 3. Symptom criteria: Meet the inclusion and exclusion criteria for each symptom cluster; 4. Fertile female subjects are not breastfeeding or pregnant at the time of enrollment (negative urine pregnancy test); 5. Willing and able to provide informed consent, complete surveys, clinical assessments, and all necessary follow-up visits; Symptom Cluster Inclusion Criteria:; Inflammatory Cardiac Involvement Symptom Cluster; 1) Age: 18-75 years old; 2) Presence of cardiac symptoms at the time of enrollment (e.g., Chest tightness after physical activity, chest pain, difficulty breathing, palpitations, fatigue, etc.); 3) CMR shows the following abnormal findings based on any of the following criteria:; a) Native T1 increase ≥ 1130 milliseconds at 3.0 T (or an increase of 1030 milliseconds at 1.5 T) and/or; b) Native T2 ≥ 39.5 milliseconds at 3.0 T (or 49.5 milliseconds at 1.5 T) and/or; c) Presence of non-ischemic myocardial and pericardial late gadolinium enhancement and/or; d) Left ventricular ejection fraction ≥ 40% and ≤50%; Cough Symptom Cluster; 1) Clinical assessment of cough according to ACCP guidelines indicates no cough caused by other diseases such as COPD, asthma, chronic bronchitis, gastroesophageal reflux, bronchiectasis, etc; 2) Chest X-ray or CT scan shows no abnormalities that could lead to cough or other serious lung diseases; 3) FENO ≥25 ppb, or the proportion of eosinophils in sputum cytology ≥2.5%; or the blood eosinophil count >0.3×10⁹/L; Fatigue Symptom Cluster; 1) Fatigue Severity Scale (FSS) average score ≥ 4; 2) Any inflammatory marker (CRP, ESR, PCT, ferritin, IL-6, TNFα) is above the upper limit of normal.

Exclusion: 1. Known SARS-CoV-2 infection within 3 months prior to the date of informed consent signature; 8. Known alcohol, drug, or chemical abuse; g) Specific cardio myopathies (hypertrophic, hypertensive heart disease, amyloidosis, previous myocarditis, non-ischemic dilated cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, non-compacted cardiomyopathy, etc.); 5) Currently taking or having used angiotensin-converting enzyme inhibitors (ACEI) within the past 3 months of screening; 6) Received any relevant traditional Chinese or Western medical treatment within the last month; 1) Received any relevant traditional Chinese or Western medical treatment within the last month, taking sedatives, hypnotics, melatonin, or antidepressants; 2) Known previous diagnosis of myalgic encephalomyelitis/chronic fatigue syndrome unrelated to SARS-CoV-2 infection; 3) Known previous autonomic dysfunction unrelated to SARS-CoV-2 infection; 2. Systemic fungal infection and active infections that cannot be controlled by anti-infective agents; 4. Known allergy/sensitivity or any hypersensitivity reaction to the study intervention or control components; 6. Any persistent central nervous system disorders, psychiatric illnesses, chronic respiratory or cardiac diseases, Underlying diseases (poorly controlled diabetes, poorly controlled hypertension, peripheral edema, cataracts or glaucoma, peptic ulcer disease, femoral head necrosis, low bone density, or osteoporosis); Inflammatory Cardiac Involvement Symptom Cluster; 1) Past medical history or cardiac magnetic resonance (CMR) evidence indicating significant cardiac disease, including:; b) Congestive heart failure (New York Heart Association Class III-IV); c) Ongoing treatment for heart failure (including HFrEF and HFpEF); d) Confirmed ischemic heart disease, peripheral artery disease, and/or cerebrovascular disease; e) Persistent or permanent atrial fibrillation or significant arrhythmias; f) Congenital or clinically relevant valvular heart disease (moderate or severe); 2) Contraindications for contrast-enhanced cardiac magnetic resonance (CMR) imaging, such as: use of implanted devices not compatible with MRI; known allergy to gadolinium-based contrast agents (CBGA); 3) Patients with structural heart disease or incidental arrhythmias detected on cardiac magnetic resonance imaging will be advised to consult their physicians; 3) Chest CT showing acute pulmonary infection-related diseases; 4) Fatigue caused by metabolism-related diseases (such as hyperthyroidism or hypothyroidism, malnutrition) that developed following SARS-CoV-2 infection; a) Known left ventricular ejection fraction (LVEF) <40% indicating cardiac dysfunction; 7. For female participants: pregnant or breastfeeding at screening, or expecting to become pregnant during the study period; women of childbearing age who are unwilling to use effective contraceptive measures (defined as PEARL index <1, such as birth control pills, intrauterine devices); 3. Current or recent (within the last 10 weeks) use of glucocorticoids, other immunosuppressants, or biologic agents; 5. Known contraindications to the study intervention; 9. Currently participating in another clinical trial; 10. Deemed ineligible to participate in this study by the investigator's assessment; Symptom Cluster Exclusion Criteria:; Cough Symptom Cluster; 1) Current smoker or having quit smoking for less than 6 months; 2) Intolerance to pulmonary function testing and/or FeNO; 4) Forced expiratory volume in 1 second (FEV1) / Forced vital capacity (FVC) ratio less than 60%; Fatigue Symptom Cluster.
