Filter by:An International Multi-Centre Randomised Adaptive Platform Clinical Trial to Assess the Clinical, Virological and Immunological Outcomes in Patients with SARS-CoV-2 Infection (COVID-19).
The study is to investigate the antibody response in the blood and saliva of people with a known COVID-19 infection in the canton of Baselland.
Problem: The COVID- 19 pandemic has not only affected our healthcare system, but the impact on the worldwide financial systems and our "normal" way of life is still to be determined. Although the percentage of patients infected with COVID-19 that need hospital care is low, Its high rate of contagiousness makes the total number of patients in need of hospital care cripple any healthcare system, limiting the space available for other patients in need of critical care, who cannot be admitted or even prefer not to attend the hospital in fear of infection. Early investigations report an Increase risk of thromboembolic complications, and a systemic inflammatory response not clearly understood. There is a possible vascular endothelial dysfunction due to chronic comorbidities (Hypertension, diabetes, obesity, chronic kidney disease, lung disease) as a risk factor for a more severe presentation. Justification: Sulodexide is a two-compound drug, each of them with different endothelial action that can be beneficial in COVID-19 patients. Glycosaminoglycans: Can help restore venous and arterial endothelial glycocalyx which can downregulate or limit the response to inflammatory molecules, by maintaining the integrity lost in certain chronic diseases (high blood pressure, diabetes). Heparin compound: It has an antithrombotic effect that could help reduce the incidence of thromboembolic complications, and also add to the anti-inflammatory response due to it anti-thrombin action (similar or a bit less to that of low molecular weight heparin) with less risk of major bleeding. It's a medication that can be used orally with minimal adverse effects and is less expensive than low molecular weight heparin. Hypothesis: We hypothesize that sulodexide instituted early in populations at significant risk and symptomatic patients affected with COVID-19 (shortness of breath, fever, weakness, diarrhoea) and risk factors of diabetes, hypertension, COPD, atherosclerosis, chronic kidney disease, will provide improvement in endothelial integrity, decrease inflammatory responses, and improved clinical outcomes with decreased hospital admission, decrease VTE and arterial complications, morbidity, and mortality. Objective: To use sulodexide in patients that have early onset of COVID-19 symptoms to mitigate the progression of the disease process that can allow them to recover at home, and limit the need of hospital care and a more severe clinical manifestation
In this 16-week randomized control study, health care workers will receive a bolus dose followed by a weekly dose of vitamin D or a placebo bolus and weekly dose. This study will test whether high-dose of vitamin D supplementation decreases the incidence of laboratory-confirmed COVID19 infection (primary outcome), reduces illness severity, duration, as well as work absenteeism among health care workers (HCW) in setting at high-risk of contact with COVID-19 cases in high COVID-19 incidence areas.
The objective of this study is to detect the evidence on the immune response following acute SARS-CoV-2 infections. the study will report the profile of IgG specific antibodies levels to SARS-CoV-2 infection found in recovered coronavirus disease (COVID-19) patients after infection for both symptomatic and asymptomatic patients.
The purpose of this study is to evaluate the tolerability, safety, pharmacokinetics of SCTA01(anti-SARS-CoV-2 monoclonal antibody) in Healthy Chinese Subjects.
The first-in-human Phase 1 study component will evaluate two dose levels of RAPA-501-ALLO off the shelf cells in patients with COVID-19-related ARDS, with key endpoints of safety, biologic and potential disease-modifying effects. The randomized, double-blind, placebo-controlled Phase 2b study component will evaluate infusion of RAPA-501 ALLO off the shelf cells or a control infusion, with the primary endpoint assessing whether RAPA-501 cells reduce 30-day mortality. The COVID-19 pandemic is a disaster playing out with progressive morbidity and mortality. As of April 6th, 2021, an estimated 132.1 million people have contracted the virus and 2,866,000 deaths have resulted globally. The United States has the highest totals with an estimated 30.8 million people diagnosed and 556,000 deaths. In stages 1 and 2 of COVID-19, viral propagation within the patient is predominant. As such, therapeutic interventions focus on immune molecules (convalescent serum, monoclonal antibodies) and anti-viral medications (remdesivir). In marked contrast, the most severe and deadly form of COVID-19, stage 3, is driven not by viral propagation, but by an out-of-control immune response (hyperinflammation) caused by increases in immune molecules known as cytokines and chemokines. As such, therapeutic interventions for stage 3 disease focus on anti-inflammatory medications such as anti-cytokine therapy (anti-IL-6 drugs) or corticosteroid therapy. Unfortunately, such interventions do not address the full pathogenesis of stage 3 COVID-19, which includes hyperinflammation due to "cytokine storm" and "chemokine storm," tissue damage, hypercoagulation, and multi-organ failure (including lung, heart, kidney and brain). The pulmonary component of stage 3 disease includes acute respiratory distress syndrome (ARDS), which is a final-common-pathway of patient death due to a myriad of conditions, including pneumonia, sepsis, and trauma. There is a dire need for novel cellular treatments that can deliver both a broad-based immune modulation effect and a tissue regenerative effect, such as RAPA-501-ALLO off-the-shelf allogeneic hybrid TREG/Th2 Cells. Stage 3 COVID-19 carries an estimated 30-day mortality of over 50% in spite of ICU utilization, mechanical ventilation, and supportive care therapies to manage ARDS and multiorgan failure. Narrowly acting targeted anti-inflammatory approaches such as anti-IL-6 therapeutics have not been particularly effective in stage 3 COVID-19 and the broad anti-inflammatory pharmaceutical approach of corticosteroid therapy, has only modestly tempered stage 3 disease in some studies. Cell therapy is also being evaluated in stage 3 COVID-19, in particular, mesenchymal stromal cells (MSC) and now, with the current RAPA-501-ALLO protocol, regulatory T (TREG) cells. TREG therapy has a mechanism of action that includes a multi-faceted anti-inflammatory effect, which puts TREG therapy at the forefront of future curative therapy of a wide range of autoimmune and neurodegenerative diseases, plus transplant complications, such as graft-versus-host disease (GVHD) and graft rejection. In addition, TREG therapy can provide a tissue regenerative effect, which places TREG cell therapy at the lead of novel regenerative medicine efforts to repair a myriad of tissue-based diseases, such as diseases of the skin, muscle, lung, liver, intestine, heart (myocardial infarction) and brain (stroke). RAPA-501-ALLO off-the-shelf cell therapy offers this potential dual threat mechanism of action that incorporates both anti-inflammatory and tissue repair effects for effective treatment of COVID-19 and multiple lethal conditions. RAPA-501-ALLO cells are generated from healthy volunteers, cryopreserved, banked, and are then available for off-the-shelf therapy anytime. During manufacturing, T cells are "reprogrammed" ex vivo using a novel, patented 7-day two-step process that involves T cell de-differentiation and subsequent re-differentiation towards the two key anti-inflammatory programs, the TREG and Th2 pathways, thus creating a "hybrid" product. The hybrid phenotype inhibits inflammatory pathways operational in COVID-19, including modulation of multiple cytokines and chemokines, which attract inflammatory cells into tissue for initiation of multi-organ damage. The hybrid TREG and Th2 phenotype of RAPA-501-ALLO cells cross-regulates Th1 and Th17 populations that initiate hyperinflammation of COVID-19. RAPA-501 immune modulation occurs in a T cell receptor independent manner, thus permitting off-the-shelf cell therapy. Finally, in experimental models of viral pneumonia and ARDS, TREG cells mediate a protective effect on the lung alveolar tissue. Because of this unique mechanism of action that involves both anti-inflammatory and tissue protective effects, the allogeneic RAPA-501 T cell product is particularly suited for evaluation in the setting of COVID-19-related ARDS.
In this trial patients will be treated with either a combination of therapies to treat COVID-19 or a placebo. Treatment will last 10 days, and patients will be followed for 6 months.
The purpose of this study is to evaluate how useful vitamin D supplementation is in reducing the severity of COVID-19 symptoms and the body's inflammatory and infection-fighting response to COVID-19. Individuals ≥50 years of age and older who are tested for COVID-19 and negative will be randomized (like flipping a coin) to either daily high dose vitamin D supplementation (6000 IU vitamin D3/day) vs. standard of care. Those individuals ≥50 years of age or older who test positive for COVID-19 at baseline will be randomized to bolus vitamin D (20,000 IU/day for 3 days) followed by high dose (6000 IU vitamin D/day) vs. standard of care for 12 months. All participants will receive a multivitamin containing vitamin D.
