Long COVID clinical trials — recruiting now

Long COVID (persistent COVID) represents a major global health challenge due to its high prevalence (approximately 7%), significant impact on quality of life, and socioeconomic burden. Despite extensive research, diagnostic tools to objectively identify or predict long COVID evolution are still lacking. The BioICOPER Follow-up Study aims to analyze the influence of biomarker evolution on clinical symptomatology (particularly chronic fatigue) and vascular health after four years of follow-up among 400 participants previously included in the original BioICOPER cohort. Advanced proteomic analysis, vascular function assessment, and machine-learning-based predictive modeling will be used to identify biomarkers associated with disease progression, stratified by sex. This project will contribute to personalized clinical management of long COVID and improved diagnostic and therapeutic strategies in primary care.

The investigators are studying the pathophysiologic links between obesity, insulin resistance (IR), adipose tissue infection, and post-acute sequelae of COVID-19 (PASC). This study looks at whether adipose (fat) tissue contributes to PASC by driving chronic inflammation or by serving as a reservoir for SARS-CoV-2 persistence. The results will not only determine whether obesity and IR are risk factors for PASC, but will also define fundamental biology that sets the stage for the investigation of novel or existing therapies that target the causal pathways identified.

By the end of 2019 a new coronavirus, named SARS-CoV-2, was discovered in patients with pneumonia in Wuhan, China. In the following weeks and months the virus spread globally, having a tremendous impact on global health and economy. To date, no vaccine or therapy is available. Severe courses of the infection not only affect the lungs, but also other organs like the heart, kidney, or liver. The lack of preexisting immunity might at least partially explain the affection of extra pulmonary organs not yet seen in infections due to other respiratory viruses. In this observational investigation the study group will follow up on patients that have been hospitalized due to a SARS-CoV-2 infection, and monitor sequelae in various organs, with an emphasis on the pulmo-cardiovascular system. Our that in some patients, organ damage will persist and require long-term medical care.

The goal of this observational study is to deepen our understanding of long COVID by determining the prevalence of the main complications and medium- to long-term sequelae of COVID-19 in Navarre. Sociodemographic variables such as age, sex, ethnicity, smoking history, and comorbidities will be collected, as well as clinical and disease management variables such as persistent COVID-19 symptoms at 3 months, all with the aim of characterizing patients with long COVID. All patient data will be collected in a single visit.

The purpose of this study is to investigate the safety, tolerability, and pharmacokinetics (PK) of single- and multiple-dose administration of S-892216-LAI in healthy adults.

Fatigue, cognitive problems, post-exertional malaise (PEM) and postural orthostatic tachycardia syndrome (POTS) are common and debilitating symptoms after COVID-19. The pathophysiology of post-COVID is not well understood and there is no established biomedical treatment. Treatment options for post-COVID are thus much needed. A promising candidate intervention is fluvoxamine, a selective serotonin reuptake inhibitor (SSRI), that may reduce post-COVID symptoms because of its regulatory effect on the (neuro) immune system, the hypothalamic-pituitary-adrenal (HPA) axis and the tryptophan system. The investigators will randomize 160 participants to either fluvoxamine or placebo for 12 weeks. The investigators will use advanced functional neuroimaging techniques during cognitive challenge (optional substudy) and plasma biomarkers (inflammatory markers, cortisol, serotonin, IDO-2 activity), to facilitate identifying potential mechanistic pathways of post -COVID treatment.

The evidence-based Concordant Care approach involves engaging in processes that: 1) validate the patient's experience, 2) develop a shared understanding of the condition, and 3) create a patient-centered, whole health-oriented action plan to manage the condition. This is consistent with published expert opinion that Concordant Care underlies patients' (and clinicians') positive experiences of care for poorly understood conditions. Despite strong evidence supporting this care approach, there are no interventions to train clinicians on practices to provide Concordant Care for Veterans with poorly understood conditions such as Long-COVID. Part 1 of the study will optimize and test if a Concordant Care training improves VA clinicians' engagement in recommended practices to provide Concordant Care (i.e., validate, shared understanding, action plan) for Veterans with Long-COVID. This study will adapt and refine Concordant Care training for Long-COVID. Part 2 of this study will determine if Concordant Care training increases clinicians' engagement in recommended practices to provide Concordant Care and will explore the effectiveness of Concordant Care on care outcomes including satisfaction, adherence to care, \& disability for Veterans with Long-COVID. Veterans treated by clinicians receiving Concordant Care training will report their clinician more frequently engaged in recommended conversations (i.e., ask about Long-COVID, validate experience with Long-COVID, create a shared understanding and action plan), and Veterans will perceive greater shared understanding of Long-COVID with their clinicians than Veterans treated by clinicians in the control arm.

This single-center, randomized, controlled, single-blind clinical trial evaluates whether a stellate ganglion block (SGB) using bupivacaine can improve persistent symptoms in adults with long COVID. Participants are assigned in a 1:1 ratio to receive either an ultrasound-guided right-sided SGB or a placebo saline injection delivered to the sternocleidomastoid muscle. After the intervention, participants are followed for 26 weeks with scheduled evaluations that include symptom questionnaires and functional tests. The study assesses changes in functional status, fatigue, cognitive complaints, quality of life, dyspnea, lower-limb endurance, and orthostatic tolerance over time. Safety is monitored throughout all follow-up visits. Approximately 40 participants meeting predefined eligibility criteria will be enrolled. This trial seeks to determine whether a single stellate ganglion block has an effect on persistent long-COVID symptoms compared with placebo.The results will help determine the therapeutic value of SGB in the management of long COVID and inform future research and clinical practice.

The trial will test if two repurposed HIV antivirals can reduce symptom burden in adult participants with Long Covid compared to placebo. Viral infection and viral reactivation have been documented in Long Covid. Participants will be randomly allocated to receive antivirals, Truvada (tenofovir disoproxil/emtricitabine, TDF/FTC, Group 1) or Selzentry (Group 2), or a placebo (pill) (Group 3), taken daily for 90 days.

Magnetic properties of myocardial tissue change in the presence of disease. This is detectable in the change of rate of magnetic relaxation, and measurable by T1 and T2 mapping using cardiovascular magnetic resonance (CMR). These markers provide novel quantifiable imaging measures for myocardial tissue characterisation. Despite similar principles, the measurements differ considerably between different sequences, vendors and field strengths, yielding a necessity to establish robust sequence-specific normal ranges, diagnostic accuracy, relationships with clinical characteristics, cardiovascular risk factors, routine cardiac imaging parameters, and prognosis. A further unknown relates to separation between healthy myocardium and subclinical disease in subgroups of patients with suspected cardiac involvement. Examples include patients with possible inflammation, such as in patients with a recent COVID-19 infection or vaccination. Anticipated recruitment of a total of 3000 subjects, with 1500 subjects per field strength (1.5 and 3.0 Tesla).

Millions have developed Long COVID (LC), and recent findings show an association between taurine deficiency (an amino acid) and symptoms in LC. Cost-effective and accessible interventions are needed to improve welfare and reduce healthcare costs. We will investigate the efficacy of 12-weeks of taurine supplementation (self-administered), on vascular function and the cardio/cerebrovascular responses to upright posture. We will measure resting vascular function with an EndoPAT device, resting heart rate variability, and the blood pressure, heart rate, and brain blood flow responses to 5 minutes of head-up tilt before and after weeks of taurine supplementation in LC. We hypothesize that the 12 weeks of supplementation will improve both resting vascular function and the responses to upright tilt. In turn, we hypothesize that symptoms will also improve (as measured by questionnaires).

The COVID-19 pandemic has swept across the globe, affecting millions of individuals with varying degrees of severity. While many individuals recover from the acute phase of the infection, a significant proportion continue to experience persistent and debilitating symptoms long after the initial SARS-CoV-2 infection. This condition, known as Long COVID (LC) or sometimes referred to as Post-COVID Condition (PCC) or post-acute sequelae of COVID-19, has emerged as a complex multisystemic condition and challenging health issue, affecting approximately 10% of COVID-19 patients. Various symptoms characterize LC, including fatigue, sleep disturbances, cognitive impairment, and mood disturbances. Some of the symptoms are shared with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) - a condition marked by debilitating fatigue and a host of other symptoms without precise biomarkers or objective tests for diagnosis. Effective LC treatments remain elusive and LC patients continue to grapple with persistent symptoms that significantly impact their quality of life. Given the lack of effective treatments, it is imperative to explore novel therapeutic approaches that may alleviate the suffering of this patient population.

Considering the compelling amount of studies focused on patients in the active phase of COVID-19 disease and the scarcity of studies focused on patient cured from disease aimed at evaluating the sequelae of SARS-CoV-2 infection, the purpose of the study is to investigate whether in patients recovered from COVID-19 disease, SARS-CoV-2 infection has induced: 1) endocrine-metabolic function damage; 2) neuro-psychiatric damage; 3) muscle damage; 4) pulmonary damage; 5) cardiological damage; 6) venous vascular damage; 7) dermatological damage. Patients will be evaluated at baseline (at discharge from infectious and/or pneumology unit) and after 3- 12 months. A better definition of the prevalence and type of sequelae after recovery from COVID-19 disease could significantly improve the therapeutic management and long-term follow-up of these patients, with a relevant impact in terms of health resources and public health.

With more than 246 million people diagnosed with coronavirus 2019 (COVID-19) around the world, many of whom have required medical attention for past 23 months, greater emphasis is being placed on post-acute care of COVID-19 survivors. According to recent data, millions of patients who have recovered from acute COVID-19 are experiencing persistent symptoms, which lead to disability and impaired activities of daily living. Various terms have been used to describe the condition of patients who do not return to their initial health status to include post-acute sequelae of COVID-19, such as post-acute COVID syndrome (PACS) and Long COVID. The growing global burden of COVID-19 suggests that the potential effects of Long COVID in public health are vast even if Long COVID is experienced by a small proportion of patients recovering from acute infection. The ability to identify patients at high risk for Long COVID and forecasting medical resource requirements is of important clinical utility in the present. In view of the large number of people surviving after infection with COVID-19 and that should require follow-up, determine which patients are at risk of have Long COVID and who require close monitoring is crucial. In this study, therefore, we set out to analyze what type of patient profile with COVID-19 who, after 12 weeks of having suffered the infection, experiences the signs and symptoms described by current literature.

Prospective cohort study to evaluate the utility of quantitative CT analysis to assess ventilation and perfusion defects in patients with Post-acute Sequelae of SARS-CoV-2 (PASC) and functional limitations

Post-acute sequelae of SARS-CoV-2 infection (PASC) is becoming a major risk factor for chronic diseases, with older adults and those with underlying health conditions at risk of developing persistent mobility limitations and disabilities. Although exercise intervention is a common strategy to restore functional capacity, it may not be feasible or enticing to many people with PASC. This clinical trial seeks to establish the tolerability and efficacy of at home lower-body heat therapy for improving functional capacity along with metabolic and vascular health in late-middle aged and older adults with PASC, also known as "long COVID".

This study will test the safety and tolerability of Anktiva in patients with Long Covid. Eligible patients will receive up to 2 doses of Anktiva and have follow-up exams and tests.

This study is investigating the effects of using an Osteopathic Manipulative Therapy (OMT) treatment protocol that was shown to statistically improve smell in individuals suffering from Long-COVID olfactory (smell) dysfunction in a small single-blinded pilot trial conducted during 2021. The questions this study is trying to answer are: 1. Does this OMT protocol improve other non-smell related Long-COVID symptoms 2. Do 2 OMT treatments improve Long-COVID symptoms more than 1 OMT treatment Participants will: 1. Week 1: Take an digital survey regarding their Long-COVID symptoms undergo Long-COVID OMT treatment or a placebo treatment 2. Week 2: Take an digital survey regarding their Long-COVID symptoms then all will undergo Long-COVID OMT treatment 3. Week 3: Take an digital survey regarding their Long-COVID symptoms 4. Week 8: Take an digital survey regarding their Long-COVID symptoms

Post-COVID-19 syndrome is associated with persistent symptoms such as fatigue, reduced physical activity, and impaired respiratory function. Circadian rhythm differences (chronotype) may influence lifestyle behaviors including physical activity, nutrition, and sleep patterns. This observational cross-sectional study aims to compare respiratory muscle strength, physical activity levels, and nutritional habits among individuals with post-COVID-19 syndrome according to their chronotype (morning, intermediate, and evening types). Additionally, genetic analysis of the CLOCK gene polymorphism will be performed to support objective evaluation of circadian rhythm differences. The findings of this study may help to better understand the role of circadian rhythm in post-COVID-19 syndrome and contribute to the development of individualized rehabilitation and lifestyle interventions.

The Coronavirus Disease 2019 (COVID-19) pandemic has resulted in persistent health problems in a significant proportion of individuals after recovery from the acute infection. These long-term manifestations, commonly referred to as post-COVID-19 condition or long COVID, may involve respiratory, cardiovascular, neurological, psychological, and general health domains. Understanding these sequelae is particularly important in patients undergoing preoperative anesthesia evaluation, as residual symptoms may influence perioperative risk assessment and clinical decision-making. This cross-sectional observational study aims to evaluate the long-term clinical and health effects of previous COVID-19 infection in adult patients presenting to the preoperative anesthesia clinic. Patients aged 18 years and older who report a history of confirmed COVID-19 infection will be included. Clinical data related to the acute infection period (disease severity, hospitalization, intensive care unit (ICU) admission, oxygen therapy, and radiological findings) will be retrospectively obtained from hospital records. At the time of preoperative assessment, participants will complete a structured post-COVID-19 clinical questionnaire to evaluate persistent symptoms across multiple organ systems. The study seeks to determine the prevalence and characteristics of long-term post-COVID-19 symptoms and to explore potential associations between acute disease severity and ongoing health complaints. No additional medical intervention will be performed as part of this research.
