Active clinical trials for "COVID-19"

This is a randomized, double-blind, placebo-controlled, multi-arm, multicenter, phase II trial design to allow a rapid efficacy and toxicity assessment of potential therapies (camostat mesilate and artemisia annua) immediately after COVID-19 positive testing in mild to moderate disease and high-risk factors such as diabetes, hypertension, and obesity among others.

This study is designed to assess the safety and tolerability of single doses of DWRX2003 in COVID-19 patients.

The purpose of this study is to evaluate the effect of the ganglion sphenopalatine block (SPG block) on persistent headache following acute COVID-19 infection.

This study is an adaptive Phase III randomized double-blind placebo-controlled trial to evaluate the efficacy and safety of Proxalutamide (GT0918) in hospitalized adults diagnosed with COVID-19. The study is a multicenter trial that will be conducted globally. The study will compare GT0918 plus standard of care (SOC) with the placebo plus SOC. Approximately 762 subjects will be randomized in a 1:1 ratio to either GT0918 plus SOC or placebo plus SOC group.

A web-based survey will be emailed to all adult women diagnosed with invasive breast cancer or ductal carcinoma in situ who have been seen as surgical consultations within the last year (06/01/19-06/01/20).

This observational study will prospectively characterize the long-term symptoms and side effects of COVID-19 in cohorts of people living with and without HIV. This will be achieved through a series of remote study visits involving completing surveys about health history, symptoms, mood, quality of life and changes in health, and up to two blood draws from home through the use of a mobile phlebotomy service.

This study evaluated the efficacy, safety, pharmacokinetics, and pharmacodynamics of ravulizumab administered in adult participants with coronavirus disease 2019 (COVID-19) severe pneumonia, acute lung injury, or acute respiratory distress syndrome. Participants were randomly assigned to receive ravulizumab in addition to best supportive care (BSC) (2/3 of the participants) or BSC alone (1/3 of the participants). BSC consisted of medical treatment and/or medical interventions per routine hospital practice.

The mortality rate of the disease caused by the corona virus induced disease (COVID-19) has been estimated to be 3.7% (WHO), which is more than 10-fold higher than the mortality of influenza. Patients with certain risk factors seem to die by an overwhelming reaction of the immune system to the virus, causing a cytokine storm with features of Cytokine-Release Syndrome (CRS) and Macrophage Activation Syndrome (MAS) and resulting in Acute Respiratory Distress Syndrome (ARDS). Several pro-inflammatory cytokines are elevated in the plasma of patients and features of MAS in COVID-19, include elevated levels of ferritin, d-dimer, and low platelets. There is increasing data that cytokine-targeted biological therapies can improve outcomes in CRS or MAS and even in sepsis. Tocilizumab (TCZ), an anti-IL-6R biological therapy, has been approved for the treatment of CRS and is used in patients with MAS. Based on these data, it is hypothesized that TCZ can reduce mortality in patients with severe COVID-19 prone to CRS and ARDS. The overall purpose of this study is to evaluate whether treatment with TCZ reduces the severity and mortality in patients with COVID-19.

Rationale: The current SARS-CoV-2 pandemic has a high burden of morbidity and mortality due to development of the so-called acute respiratory distress syndrome (ARDS). The renin-angiotensin-system (RAS) plays an important role in the development of ARDS. ACE2 is one of the enzymes involved in the RAS cascade. Virus spike protein binds to ACE2 to form a complex suitable for cellular internalization. The downregulation of ACE2 results in the excessive accumulation of angiotensin II, and it has been demonstrated that the stimulation of the angiotensin II type 1a receptor (AT1R) increases pulmonary vascular permeability, explaining the increased lung pathology when activity of ACE2 is decreased. Currently available AT1R blockers (ARBs) such as valsartan, have the potential to block this pathological process mediated by angiotensin II. There are presently two complementary mechanisms suggested: 1) ARBs block the excessive angiotensin-mediated AT1R activation, and 2) they upregulate ACE2, which reduces angiotensin II concentrations and increases the production of the protective vasodilator angiotensin 1-7. In light of the above, ARBs may prevent the development of ARDS and avert morbidity (admission to intensive care unit (ICU) and mechanical ventilation) and mortality. Objective: To investigate the effect of the ARB valsartan in comparison to placebo on the occurrence of one of the following items, within 14 days of randomization:1) ICU admission; 2) Mechanical ventilation; 3) Death. Study design: A double-blind, placebo-controlled 1:1 randomized clinical trial Study population: Adult hospitalized SARS-CoV-2-infected patients (n=651). Intervention: The active-treatment arm will receive valsartan in a dosage titrated to blood pressure up to a maximum of 160mg b.i.d. and the placebo arm will receive a matching placebo also titrated to blood pressure. Treatment duration will be 14 days or up to hospital discharge < 14 days or occurrence of the primary endpoint if < 14 days. Main study endpoint: The primary study endpoint is the occurrence within 14 days of randomization of either: 1) ICU admission; 2) Mechanical ventilation; 3) Death.

The outbreak of a novel coronavirus (SARS-CoV-2) and associated COVID-19 disease in late December 2019 has led to a global pandemic. At the time of writing, there have been 150 000 confirmed cases and 3500 deaths. Apart from the morbidity and mortality directly related to COVID-19 cases, society has had to also cope with complex political and economic repercussions of this disease. At present, and despite pressing need for therapeutic intervention, management of patients with COVID-19 is entirely supportive. Despite the majority of patients experiencing a mild respiratory illness a subgroup, and in particular those with pre-existing cardiovascular disease, will experience severe illness that requires invasive cardiorespiratory support in the intensive care unit. Furthermore, the severity of COVID-19 disease (as well as the likelihood of progressing to severe disease) appears to be in part driven by direct injury to the cardiovascular system. Analysis of data from two recent studies confirms a significantly higher likelihood of acute cardiac injury in patients who have to be admitted to intensive care for the management of COVID-19 disease. The exact type of acute of cardiac injury that COVID-19 patients suffer remains unclear. There is however mounting evidence that heart attack like events are responsible. Tests ordinarily performed to definitely assess for heart attacks will not be possible in very sick COVID-19 patients. Randomising patients to cardioprotective medicines will help us understand the role of the cardiovascular system in COVID-19 disease. It will also help us determine if there is more we can do to treat these patients.
