COVID-19 Clinical Trials and Expanded Access

Investigating the role of 13cis retinoic acid in the treatment of COVID-19 and enhancement of Its spike protein based vaccine efficacy and safety.

This study investigates the possible adverse effects and effectiveness of convalescent plasma for patients infected with SARS-CoV-2. Following provision of informed consent, patients will be randomized into three groups: High-titre convalescent plasma, low-titre convalescent plasma or placebo. Primary outcomes of the study will cover safety and either intubation or initiation of systemic corticosteroids. Safety information collected will include serious adverse events judged to be related to administration of convalescent plasma. Microbiological and other laboratory parameters will be followed up.

A Study of the relation of COVID-19 infection and its severity to upper and lower airway nitric oxide, upper airway viral load and lung function.

COVID-19 is a severe disease with poor prognosis in patients receiving in-center haemodialysis (HD). A population-based registry of >4,000 patients with a diagnosis of COVID-19 receiving kidney replacement therapy (either haemodialysis or kidney transplant recipient) highlighted a 21.1 fold higher 28-day mortality risk among patients on dialysis (n = 3,285), than the expected 1.2% mortality of propensity-score matched historical controls. Vulnerability in uraemic patients is a combination of intrinsic frailty, increased risk of infection and a high burden of comorbidities. In patients on HD, abnormalities in the immune response may contribute to relative hyporesponsiveness to vaccines. However, patients on HD appear to seroconvert at a similar rate compared to the general population after SARS-CoV-2 infection, suggesting a likelihood of vaccine efficacy but this population has been excluded from vaccine trials. The primary aim of this study is to evaluate antibody synthesis induced after Covid-19 vaccination in a French adult multicentric cohort of in-center haemodialysis patients. The second aim of this study is to identify vaccine non-responders among HD patients and to assess the clinical and biological risk factors associated with non-response.

This is a phase Ib trial with SAR439459, a TGF-beta inhibitor, in combination with cemiplimab, a PD-L1 inhibitor, in patients with solid tumors that have spread to other places in the body (advanced) or cannot be removed by surgery (unresectable). Inhibiting TGF-beta may interfere with the ability of cancer cells to grow and spread and may sensitize cancers to immune checkpoint inhibitor therapy. The objective of this study is to determine whether this drug combination is effective in shrinking cancers, keeping them from growing, helping patients live longer, and to see if the drug combination is safe.

COVID-19 can cause myocarditis, which can cause myocardial fibrosis. This has been shown to increase mortality and morbidity among athletes. Several efforts have been made to guide sports participation after COVID-19, but not much scientific evidence is present to back-up those guidelines. The current initiative aims gain a heightened insight in this matter.To identify the presence of fibrosis athletes who recovered from COVID-19 will undergo CMR (Cardiac MRI). All athletes will also undergo echocardiography, 5-day Holtermonitoring among others. This will allow to determine whether differences between those with and those without fibrosis are present. If fibrosis is present, athletes will be offered an implantation of a very small monitoring device that will be able to detect arrhythmias with a much higher sensitivity. Also an exercise echocardiography will be performed, to determine the safety of continuation of athletic efforts. Amendment: Recently myocarditis and pericarditis have also been observed after the administration of mRNA-vaccines, specifically after the second dose. The effect of vaccination on exercise capacity is less clear. To investigate this we propose to amend the inclusion criteria for COVIDEX with "athletes undergoing or having undergone COVID vaccination"

This is a prospective single-center study for the follow-up of SARS-CoV-2 positive patients in the district of Konstanz (LKN). As part of the coronavirus pandemic, patients with SARS-CoV-2 infection are currently being treated in the clinics of the LKN's health network at the Singen (Hegau-Bodensee Clinic) and Konstanz (Konstanz Clinic) locations. So far, there is little data on the long-term effects of SARS-CoV-2 infection. As part of this study, the disease progression of these patients will be monitored. Study objective: Prospective, controlled follow-up observation of SARS-CoV-2 positive patients regarding their secondary diseases and quality of life.

Acute treatment of COVID-ARDS with direct topical lung instilled T3 therapy for patients on mechanical ventilation.

The overall objective of this study is to evaluate the clinical efficacy of oral famotidine in symptomatic non-hospitalized patients with confirmed COVID-19. This study is expected to enroll up to 84 patients with mild to moderate symptoms divided into each of the two study arms. Clinical outcomes of the two treatment arms will be compared. This study will be conducted virtually/remotely.

The purpose of this study is to test the effectiveness of prophylactic mouth rinses in reducing the amount of viruses, specifically SARS-CoV-2 in the oral cavity. This research will guide dental and medical providers on best practices to be performed prior to dental and medical procedures involving the oral cavity.
