COVID-19 Clinical Trials and Expanded Access

Estimation of the prevalence and contagiousness of undocumented novel coronavirus infections is critical for understanding the overall prevalence and pandemic potential of this disease. It is estimated that 86% of all infections were undocumented [95% credible interval (CI): 82-90%] before the 23 January 2020 travel restrictions. The transmission rate of undocumented infections per person was 55% the transmission rate of documented infections (95% CI: 46-62%), yet, because of their greater numbers, undocumented infections were the source of 79% of the documented cases. Ivermectin + Carrageenan, taking advantage of their virucidal effects, are aimed at reducing the contagion.

The epidemic of covid-19 has spread all over the world and has a great impact on people's health and life. It is necessary to study the treatment of STEMI patients in the real world under the influence of the epidemic,which provide effective suggestions and strategies for emergency and severe treatment.

The aim of the study is to explore the psychological effects of the COVID-19 pandemic among Hungarian adults with the use of an anonymous online questionnaire that consists of 65 items. With these results it will possible to identify coping strategies that can help Hungarian adults to deal with the difficulties arising from the pandemic.

SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), has negatively impacted global health and requires more research to develop better tests and to improve disease treatment. The purpose of this research is to aid in the testing effort by collecting samples from people who have been diagnosed with COVID-19 or are suspected of having COVID-19. Samples you provide will be used investigationally by INanoBio to develop a test to determine when antibodies against various SARS-CoV-2 proteins are detectable. Up to approximately 80 subjects of all ages with either a suspected or lab-confirmed diagnosis of COVID-19 will take part in this research.

In January 2020, the new SARS-CoV-2 coronavirus was identified in China. The disease caused by this coronavirus was named COVID-19 by the World Health Organization (WHO). Since March 11, 2020, the WHO has described the global situation of COVID-19 as a pandemic. In Côte d'Ivoire, as in other African countries, the number of cases is increasing exponentially. Coronaviruses are a family of viruses that cause illnesses ranging from the common cold to more severe pathologies. COVID-19 can result in fever or a feeling of fever (chills, hot-cold), cough, headache, aches and pains, unusual tiredness, sudden loss of smell, total disappearance of taste, or diarrhea. In severe forms, respiratory difficulties can lead to hospitalization in intensive care or even death. Numerous studies are currently being conducted around the world to seek effective treatment, but few of them have started specifically in Africa. Moreover, most of these studies are using a single drug to control the infection, whether these are repositioned drugs, i.e. already being used for other diseases, or other newer drugs. Currently in Côte d'Ivoire, the preferred treatment for COVID-19 is an antiviral: lopinavir/ritonavir (LPV/r), usually directed against the Human Immunodeficiency Virus (HIV). Since the number of viruses (viral load) is high in the respiratory tract during COVID-19 infection, we propose in INTENSE-COV (ICOV) clinical trial to study whether the combination of two drugs is more effective than taking a single drug on reducing the viral load in the respiratory tract but also on reducing inflammation. These drugs include the LPV/r already in use in Côte d'Ivoire as well as an antihypertensive drug - telmisartan, and a drug that lowers blood cholesterol - atorvastatin. All three have been known for a long time and have been shown to be effective against other viruses. In addition, they are generic, inexpensive and readily available in all countries. The objectives of the ICOV study are therefore to improve viral eradication from the patient's body and respiratory tract, to reduce inflammation, to improve more rapidly the patient's state of health and to reduce the risk of transmission of the virus to others. To participate in ICOV, patients must be over 18 years of age, have a COVID-19 infection confirmed by a specific test, have clinical manifestations of the infection, and have signed an informed consent. They will then be randomized into 3 treatment groups to ensure the robustness of the study results. The reference group will be treated with LPV/r, according to current recommendations in Côte d'Ivoire. The other 2 groups will be treated with LPV/r + telmisartan and LPV/r + atorvastatin respectively. The treatment will last 10 days and patients will be followed for a total of 28 days.

The objectives of this proposal are to: 1) determine the rate of SARS-CoV-2 seroconversion in unselected pregnant women in Hong Kong; 2) determine the rate of SARS-CoV-2 infection in women presenting with miscarriage and stillbirth; 3) follow the pregnancy course and perinatal outcome of confirmed COVID-19-infected pregnant cases; 4) determine the risk and characteristics of vertical transmission; and 5) evaluate the placental barrier, immune response and fetal damage in vertical transmission of SARS-CoV-2. A series of longitudinal and cross-sectional observational studies, and a laboratory-based study will be conducted to fulfil the 5 objectives.

Although arrhythmias appear to be common in COVID-19 patients, arrhythmia mechanisms and characteristics, predisposing factors, incidence of sudden cardiac death and predictors, therapeutic strategies employed as well as long term outcomes are not well understood. Hence, we seek to develop a multicenter registry aimed to characterize arrhythmic manifestations, employed treatment strategies and long-term outcomes among hospitalized COVID-19 patients in the US.

The purpose of this study is to assess the efficacy and safety of the administration of anti-SARS-CoV-2 convalescent plasma in COVID-19 patients who are sick enough to warrant hospitalization, but not yet admitted to the ICU (prior to the onset of overwhelming disease including a systemic inflammatory response, sepsis, and/or ARDS).

A total of 900 subjects are planned to be randomly divided into 2 doses of low-dose experimental vaccine group, 2 doses of high-dose experimental vaccine group, 2 doses of placebo group, 3 doses of low-dose experimental vaccine group, 3 doses of high-dose experimental vaccine group and 3 doses of placebo group, the sample size of each group was 150 cases.

Coronavirus Disease 2019 (COVID-19) is spreading worldwide and has become a public health emergency of major international concern. Currently, no specific drugs or vaccines are available. For severe cases, it was found that aberrant pathogenic T cells and inflammatory monocytes are rapidly activated and then producing a large number of cytokines and inducing an inflammatory storm. Mesenchymal stem cells (MSCs) have been shown to possess a comprehensive powerful immunomodulatory function. This study aims to investigate the safety and efficacy of intravenous infusion of mesenchymal stem cells in severe patients with COVID-19.
