Active clinical trials for "Virus Diseases"

This community-based mixed methods study intends to identify, explore, and assess the determinants of community preparedness for outbreak situations, including acceptance for Ebola vaccines.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the most frequent complications of the COVID-19 pandemic. In these conditions, hypoxemia may result from : i) a pulmonary vascular dilatation resulting from an impaired hypoxic pulmonary vasoconstriction and leading to ventilation-perfusion mismatching within the lungs and ii) thrombosis-mediated perfusion defects. Pulmonary vascular dilation might be due to a relative failure of the physiological acute hypoxic pulmonary vasoconstriction, in the context of an over-activation of a regional vasodilatation cascade, as part of a dysfunctional inflammatory process. Perfusion abnormalities associated with pulmonary vascular dilation are suggestive of intrapulmonary shunting toward areas where gas exchange is impaired, ultimately leading to a worsening ventilation-perfusion mismatch, a regional hypoxia and a profound hypoxemia. Increased plasma levels of VEGF have been reported in moderate to severe COVID-19 pneumonia, highlighting the role of VEGF in the pathophysiology of the disease. A better prognosis has been reported in critically ill patients with lower levels of growth factors, HGF and VEGF-A at the time of ICU admission. Recent data of the study NCT 04275414 by Pang J et al have suggested that patients receiving a single-dose of bevacizumab have improved their oxygen support status in 92% of cases during a 28-day follow-up period, as compared with 62% of cases in an external cohort receiving standard care. Correcting endothelial permeability and vasodilatation with VEGF-targeted therapy could allow repair damaged vascular endothelium, have an indirect anti-inflammatory effect (limiting alveolar exudation of circulating inflammatory and procoagulant mediators) and improve oxygenation and therefore reduce the proportion of patients with severe forms requiring ICU referral and finally patient death. This clinical trial will therefore focus on the specific efficacy of bevacizumab in COVID-19 patients with severe hypoxemia.

The purpose of this study is to evaluate the efficacy in terms of hepatitis B surface antigen (HBsAg) levels of the study intervention (that is, JNJ-73763989 + JNJ-56136379 + nucleos[t]ide analog [NA] and pegylated interferon alpha-2a [PegIFN-alpha2a]).

Coronavirus Disease 2019 (COVID-19) was first isolated in Wuhan, China in December 2019. It is rapidly spreading worldwide, posing a severe threat to global health. Many therapeutics have been investigated for the treatment of this disease with inconclusive outcomes. Anakinra - an interleukin (IL)-1 receptor antagonist - had showed survival benefits in patients with macrophage activation syndrome (MAS) and sepsis and was investigated for the use in COVID-19 infection with promising outcomes.

Molecular techniques for respiratory virus detection have already shown benefits in terms of sensitivity gained in comparison to conventional techniques. Recent progress has made it possible to shorten turnaround time (TAT) and to allow delivery of results in a timely manner, especially in comparison to cell culture and direct fluorescence assays (DFA). However, the cost of these molecular assays is usually not taken in charge by public health insurance system. This could be partly explained by the fact that molecular techniques have not clearly shown cost-effectiveness. Results of molecular tests for influenza viruses and RSV, if delivered rapidly, in the emergency room (ER), would most likely help avoid antibiotic use and ancillary test prescription, improve antiviral prescription and shorten length of stay in the ward by facilitating discharge or cohorting of hospitalized patients. The goal of this study is to assess the performances of Roche Cobas® Liat Influenza A/B & RSV assay, to appraise its clinical impact and to evaluate its cost effectiveness.

A Phase I dose-escalation study to test a new monoclonal antibody (called MAD0004J08) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19 disease. The study aims to evaluate the safety and pharmacokinetics (distribution and elimination) of anti-SARSCoV-2 monoclonal antibody in healthy adults. The primary objective of the study is to evaluate the safety of anti-SARSCoV-2 monoclonal antibody (that is the appearance of adverse events), the pharmacokinetics (how MAD0004J08 is distributed and eliminated by human body), the generation of anti-drug antibodies (ADAs) (that is the possible production of antibodies against the drug, which could invalidate it efficacy) and finally the ability of MAD0004J08 to neutralize SARSCoV-2. Furthermore a blood sample would be used to evaluate a kit (DIESSE kit), developed by Toscana Life Sciences, able to detect the administered drug. This kit is not used to evaluate study paramethers. 30 subjects, that should respect the Inclusion/Exclusion criteria, will be enrolled. About 12 visits will be performed during the study, study duration will be about 6 months. Subjects will be distributed into 3 Cohorts, each of them divided into 2 groups that would receive MAD0004J08 (Dose 1 = 48 mg, Dose 2 = 100 mg or Dose 3 = 400 mg) or placebo. Administration occurs as intramuscular injection (single injection for Cohort 1 and Cohort 2 and, two injections for Cohort 3) .

Reduxium is a dietary supplement that provides immune support. This natural compound is orally-ingested in the form of droplets in water to boost the immune system and control inflammation. There is not enough data on the mechanism associated with the action of Reduxium or the extent of the immune response increase it produces. In this study, the investigators propose treating a group of healthy volunteers with Reduxium and investigate the utility of this approach in boosting the native and adaptive immune responses that correlate with immune protection. This may form the basis for a future study employing the product in infectious disease patients.

Human Papillomavirus (HPV) 16 and HPV 18 (the two virus genotypes targeted by the ProCervix vaccine) are the most common HPV genotypes associated with at least 70% of squamous cell carcinomas and 82% of adenocarcinomas of the cervix The strategy of therapeutic vaccination with ProCervix is to activate and enhance the patient's cellular immune response to HPV . The therapeutic vaccine will be used for women infected by HPV 16, HPV 18, or both. The vaccine targets these HPV infected women with normal or mild cervical cellular dyskaryosis as detectable infections with oncogenic potential. This will be a double-blind, randomised, placebo-controlled, parallel group study assessing the efficacy of ProCervix or placebo (concomitantly administered with imiquimod cream). ProCervix will be delivered with a topical agent, imiquimod, applied to the injection sites as a vaccine adjuvant. The population proposed for this study represents an otherwise healthy female population who are infected with HPV 16 and/or HPV 18. The safety and tolerability of this therapeutic vaccine has been shown in the ongoing Phase I study, and the proposed population may in theory derive benefit from this vaccine.

This study is examining the safety and efficacy of converting anti-rejection therapy from mycophenolic acid (MPA) to Zortress (everolimus) in renal transplant recipients with BK virus infection. The study will also determine if immune monitoring tests can detect an association between BK virus infection and transplant rejection episodes, based on the specific BKV infection treatment regimen. The investigators hypothesize that an anti-rejection regimen with Zortress (everolimus) and tacrolimus + prednisone will be superior to a standard regimen of reduced dose MPA and tacrolimus + prednisone in patients who have undergone renal transplantation and have active BKV infections.

This clinical study is looking at a vaccine called MVA-EBNA1/LMP2. This is a new vaccine that has already been studied in small number of cancer patients. The vaccine is designed to boost a patient's immunity against a common virus. The virus is called Epstein Barr virus or EBV. EBV is sometimes found inside cancer cells and is commonly found in nasopharyngeal cancer cells.
