Filter by:This is a randomized, double-blind, placebo-controlled, multicenter, 28-day study of adult participants hospitalized with COVID-19, with a safety follow-up telephone call at Day 60.
An observational study of consecutive patients testing positive for COVID-19 who require admission to hospital to determine the degree of myocardial injury through biomarkers and echocardiography and the impact of this on cardiovascular outcomes. The COVID-19 disease and CARdiac Events study (COVICARE).
Background: The rapid spread and high infectivity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) makes identifying an effective prophylaxis agent highly important. One of the important target populations for such intervention who are at high risk of exposure are health care workers (HCWs) who may develop disease and/or expose patients and other HCWs. Hydroxychloroquine (HCQ), currently in usage for treatment of severe Coronavirus Disease 2019 (COVID-19), has in addition to in-vitro activities of inhibition of virus replication and immunomodulation, an important role in the inhibition of pre-entry step of the virus to host cells. Such activity in the early stage of infection may play a role in prevention of disease progression. Objectives: To evaluate the effect of HCQ in prevention of clinical disease and reduction of viral shedding among HCWs following exposure to confirmed COVID-19 patients. Study design: Multi-center, randomized controlled, superiority, open label trial Setting: The study will be conducted at Rambam Health Care Campus. Eligibility: Participants eligible for inclusion will include non-pregnant adult (>18 years old) HCWs who were exposed to a confirmed case of COVID-19 without full adherence to droplet precautions. Participants will be eligible in a period no longer than 72 hours after exposure. Intervention: HCQ will be given in the intervention group in a dosage regimen of 400mg BID in the first day followed by 200mg BID for overall 10 days. Participants in the control group will receive no treatment. Treatment will be started no longer than 72 hours following exposure. Outcomes: The primary outcome will be the number of participants who develop clinical signs compatible with COVID 19 (defined in full protocol) within 14 days of exposure. Secondary outcomes will include virologically-confirmed COVID 19, disease severity (need for hospitalization, mechanical ventilation and 30-day mortality) and viral shedding duration (time between first positive PCR to last of two consecutive negative tests) for confirmed COVID 19 cases. Sample size: The trial will test for HCQ's superiority assuming a primary outcome incidence of 20% in the control group and a reduction of 50% with HCQ. The sample size required for a power of 80% (alpha 0.05) is 291 participants per each group.
Stem cell therapy has emerged as a revolutionary treatment for diseases that were considered untreatable only a few years ago. Umbilical cord-derived mesenchymal stem cells (UCMSCs) have been shown to repair damaged liver, kidney, heart, pancreas, skin, cartilage, and cornea in animal models and several human trials. In addition to cellular replacement through regeneration, UCMSCs mediate through paracrine signaling pathways resulting in immune modulation. Clinical manifestations of coronavirus disease 2019 (COVID-19), are believed to arise from septic shock and cytokine storm that cause acute respiratory dysfunction and acute cardiac injury. There is presently no cure for the COVID-19 viral disease; however, multi-treatment strategies are being examined. During the past two months, four reports were published that suggest, mesenchymal stem cells (MSCs), owing to their powerful immunomodulatory ability, may prevent the cytokine storm and thus reduce the COVID-19 related morbidity. All studies reported that COVID-19 patients responded favorably to MSCs therapy. These reports, taken together with the previous successes of stem cell therapy in animal models, the investigators, a seven-institution consortium, propose to explore the efficacy of UCMSC treatment in COVID-19 patients at Jinnah hospital, Lahore. The investigators propose to administer UCMSCs in patients with acute pulmonary inflammation due to COVID-19 infection with moderate to severe symptoms. In the first cohort of 15 patients, UCMSCs will be administered with three intravenous infusions of 500,000 UCMSCs per Kg body weight each on days 1, 3, and 5. The second group of five patients serving as control will only receive standard treatment. During the 30-day post-infusion period, a battery of tests will be performed to evaluate the safety and efficacy of the UCMSCs treatment. In parallel, the investigators propose a comparative study to determine COVID-19 viral count by quantitative real-time PCR and through viral coat protein ELISA, developed in the investigator advisor lab (Dr. Tauseef Butt, Progenra Inc. Philadelphia, USA) with the ultimate objective to locally developing a rapid diagnostic assay.
First epidemiological data about COVID-19 pandemic confirm that older adults are likely to experience severe and lethal forms of SARS-CoV-2 infection, in particular frail elderly living in nursing-homes. Vitamin D could be a biological determinant of COVID-19, as indicated by genomic-guided tracing of SARS-CoV-2 targets in human cells. Epidemiological observational data are necessary for better understanding the links between vitamin D supplementation and COVID-19 outcomes, in particular in nursing-homes (in which the risk of hypovitaminosis D is very high). The investigators had the opportunity to use information collected in a French middle-sized nursing-home affected by COVID-19 in March-April 2020, to determine whether recent vitamin D3 supplementation was associated with the prognosis of COVID-19 in residents infected with SARS-CoV-2. As recommended in French nursing-homes, all residents are systematically and regularly supplemented with bolus vitamin D3 (every single, 2 or 3 months, depending on residents). The main objective of this study is to determine whether bolus vitamin D3 supplementation taken during or in the month before COVID-19 was effective in improving survival among frail elderly nursing-home residents infected with COVID-19 compared to those having received supplementation longer ago. The secondary objective is to determine whether bolus vitamin D3 supplementation taken during or in the month before COVID-19 was effective in limiting the clinical severity of the infection according to the World Health Organization's Ordinal Scale for Clinical Improvement (OSCI) for COVID-19 compared to those having received supplementation longer ago.
Shaare-Zedek Medical Center is a tertiary academic hospital in Jerusalem, Israel. On March 2020, a dramatic increase in the number of COVID-19 cases were diagnosed in Jerusalem. RedHill Biopharma, Ltd. offered opaganib under compassionate use for the treatment of COVID-19 patients. Eligible patients were those hospitalized with COVID-19 confirmed by a reverse-transcriptase-polymerase-chain-reaction assay. Patients received opaganib and Standard of Care. For the purpose of this study, the opaganib and Standard of Care patient group was compared to a group of patients that received only Standard of Care. Opaganib is an investigational drug under development and not approved for commercial distribution.
The purpose of the study is to determine if high dose Intravenous IVIG plus SMT can reduce the proportion of participants dying or requiring intensive care unit (ICU) admission on or before Day 29 or who are dependent on high flow oxygen devices or invasive mechanical ventilation on Day 29 versus SMT alone in hospitalized participants with COVID-19.
The goal of this study is to evaluate the safety and effectiveness of Coronavirus-90 (COVID-19) convalescent plasma for the treatment of COVID-19. Plasma is the liquid part of blood that is left when all the blood cells have been removed. Convalescent means it is taken from people who were infected with COVID-19 and recovered. The use of this blood product to treat COVID-19 is investigational, which means the U.S. Food and Drug Administration has not yet approved it to be sold commercially. This is a human blood product collected by licensed blood banks. Donors of COVID-19 convalescent plasma must meet all standard blood donor criteria and must also meet all criteria set by the FDA for being a donor of COVID-19 convalescent plasma. A total of 500 patients will take part in the study at 8 hospitals within Beaumont. Similar studies are being done at other centers, but they are not directly related to this study. Participants will be assigned to a study group depending on how sick they are. - Group A: Those who require more than 6 liters (L) of supplemental oxygen but are not on a ventilator - Group B: Those who require a ventilator to preserve their life. Both groups will receive one unit (approximately 200ml or just under 1 cup) of COVID convalescent plasma. The transfusion will be given over about 30 minutes via an IV. Blood samples will be taken prior to and one hour after the transfusion to measure participant antibodies against Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) and a nasopharyngeal swab (deep in the nostril) will be taken to test for presence of the SARS-CoV-2 virus. One hour after the transfusion a blood sample will be taken to measure antibody levels to determine if the plasma caused the antibody level to rise. Similarly, blood samples will be taken to measure antibodies against SARS-CoV-2 and a nasopharyngeal swab will be taken to test for presence of the SARS-CoV-2 virus 1, 3 and every 7 days after the transfusion while the participant is in the hospital The participant's final health status will be determined on day 28. Hospital records will be monitored for 90 days after discharge to determine if the participant is readmitted to the hospital.
In December 2019, a group of patients with pneumonia of unknown cause was linked to a wholesale seafood market in Wuhan, China. The genetic analysis of samples from the lower respiratory tract of these patients indicated a new coronavirus as the causative agent, which was named SARS-CoV-2. The virus spread rapidly to more than 45 countries, including Brazil, causing an international alarm. However, in spite of its epidemiological magnitude, so far, there is no antiviral treatment or vaccine approved for the treatment of this infection. With about 15% to 20% of SARS-CoV-2 patients suffering from serious illnesses and overburdened hospitals, therapeutic options are desperately needed. So, instead of creating compounds from scratch that can take years to develop and test, researchers and public health agencies have sought to redirect drugs already approved for other diseases and known to be widely safe. In this context, the analysis of the international literature shows the existence of an in vitro antiviral activity of ivermectin against SARS-CoV-2. However, there are no studies that have evaluated its clinical effectiveness in patients diagnosed with SARS-CoV-2 infection. Therefore, and considering this knowledge gap, the present study aims to determine the clinical efficacy and safety of different doses of ivermectin in patients diagnosed with SARS-CoV-2 infection.
In this study, the investigator examined epidemiological and demographic characteristics, risk factors and 28-day mortality of patients admitted to the intensive care unit with the diagnosis of coronavirus disease 2019 pneumonia.
