They include post-COVID-19 syndrome and similar illnesses following other infections. Some people with PAIS develop myalgic encephalomyelitis\u002Fchronic fatigue syndrome (ME\u002FCFS), a serious and disabling illness that can greatly limit everyday activities. People with ME\u002FCFS may experience severe fatigue, reduced physical and mental function, pain, sleep problems, and problems with the regulation of heart rate and blood pressure. A key feature is post-exertional malaise (PEM), in which symptoms become worse after physical or mental activity. The biological causes of PAIS and ME\u002FCFS are not fully understood, and there is currently no established treatment that targets the underlying disease process.\n\nResearch suggests that changes in the immune system may contribute to PAIS and ME\u002FCFS in some patients. In particular, B cells (a type of immune cell) and autoantibodies (antibodies that react with the body's own structures) may play a role. Previous studies of immunoadsorption, a procedure that removes antibodies from the blood, have shown improvements in some patients with ME\u002FCFS. These findings support further investigation of treatments that target B cells in selected patients.\n\nThe PIONEER\\_PAIS study will investigate whether inebilizumab can improve physical function in adults with PAIS who meet the diagnostic criteria for ME\u002FCFS. The study includes a selected group of patients with evidence of autoantibodies and immune activation who previously improved after immunoadsorption but later experienced worsening of their symptoms. Inebilizumab is a monoclonal antibody that targets CD19, a protein found on B cells, and leads to the depletion of these cells.\n\nParticipants will be randomly assigned to receive either inebilizumab or placebo (saline solution) as an infusion into a vein. Inebilizumab will be given at a dose of 300 mg on Day 1, Day 15, and Week 24. The study is double-blind, meaning that neither the participants nor the study team assessing them will know which treatment they receive.\n\nThe main research question is whether treatment with inebilizumab leads to a greater improvement in physical function (PF) than placebo. PF will be measured using the PF scale of the SF-36 health questionnaire, comparing the change from the start of the study to Month 9 (Week 36).\n\nThe study will also examine other aspects of health and daily functioning, including fatigue, post-exertional malaise, pain and headache, disability, symptoms related to the autonomic nervous system, muscle strength and fatigability, heart rate and blood pressure responses during standing, daily step count, and cognitive function. Adverse events will be monitored to assess the safety of the treatment. In addition, the study includes biomarker research focusing on B cells, autoantibodies, and other markers in the blood.\n\nThis research aims to explore biological characteristics that may be associated with response to treatment and may help inform future studies of B-cell-targeted treatment in PAIS and ME\u002FCFS.",[28,29,30],"Post-acute Infectious Syndrome (PAIS)","Post-COVID 19 Condition (PCC or Long COVID)","Myalgic Encephalomyelitis\u002FChronic Fatigue Syndrome (ME\u002FCFS)",[32,33,34,35],"PAIS","Long COVID","ME\u002FCFS","Fatigue","NOT_YET_RECRUITING","2026-07-21",{"date":39,"type":40},"2026-07-24","ACTUAL",{"date":42,"type":22},"2026-12-01",{"date":44,"type":22},"2029-03-01",{"name":46,"class":47},"Charite University, Berlin, Germany","OTHER",1,{"id":50,"slug":51,"hasResults":11,"nctId":52,"briefTitle":53,"officialTitle":54,"acronym":55,"eligibilityCriteria":56,"healthyVolunteers":11,"sex":17,"minAge":18,"maxAge":19,"enrollmentInfo":57,"targetDuration":4,"studyType":59,"phases":4,"briefSummary":60,"conditions":61,"keywords":63,"overallStatus":67,"whyStopped":4,"lastUpdateSubmitDate":68,"lastUpdatePostDateStruct":69,"startDateStruct":71,"completionDateStruct":73,"leadSponsor":75,"locationsCount":48},"100633631","observational-study-on-immunoadsorption-ia-in-patients-with-autoantibody-positive-post-infectious-mecfs-100633631","NCT07529197","Observational Study on Immunoadsorption (IA) in Patients With Autoantibody-Positive Post-Infectious ME\u002FCFS","Observational Study on Immunoadsorption (IA) in Patients With Autoantibody-Positive Post-Infectious Myalgic Encephalomyelitis\u002FChronic Fatigue Syndrome (ME\u002FCFS)","IMPACT","Inclusion Criteria:\n\n* Patients aged 18-65 years who are able to give informed consent and have: i) ME\u002FCFS diagnosed according to the CCC, with exertion intolerance and symptom worsening (post exertional malaise = PEM) lasting at least 14 hours and ii) Significant functional impairment with a Bell Disability Score \\\u003C 60\n* Presence of autoantibodies (adrenergic or antineuronal antibodies)\n* Undergoing IA with the TheraSorb® column over 5 days\n* Written informed consent provided by the patient\n* Health insurance coverage\n\nExclusion Criteria:\n\n* Lack of willingness to store pseudonymized disease data as part of the study\n* Pregnancy\n* Presence of other conditions that prevent a definite ME\u002FCFS diagnosis (e.g., heart failure, lung disease, severe depression, cancer)\n* Acute infection (COVID, HIV, hepatitis)\n* Severe fatigue disease with bedriddenness (Bell Disability Score \\\u003C 30)",{"count":58,"type":22},50,"OBSERVATIONAL","Myalgic Encephalomyelitis\u002FChronic Fatigue Syndrome (ME\u002FCFS) is a severe, often infection-triggered disease characterized by debilitating fatigue and post-exertional malaise lasting over 14 hours, along with pain, cognitive impairment, autonomic dysfunction, and sleep disturbances.
