Filter by:COVID-19's mechanism to enter the cell is initiated by its interaction with its cellular receptor, the angiotensin-converting enzyme. As a result of this union, a clathrin-mediated endocytosis process begins. This route is one of the therapeutic targets for which available drugs are being investigated in order to treat COVID-19 infection. This is one of the mechanisms blocked by drugs like ruxolitinib and chloroquine. Various drugs approved for clinical use that block the clathrin-mediated endocytosis pathway have been explored. It has been found that the best in vitro and in vivo results were obtained with statins, which also allowed generating a greater potent adaptive immune response. Therefore, statins and specifically simvastatin make it possible to block the entry process used by COVID-19, block inflammation by various mechanisms and increase the adaptive immune response. All of these processes are desirable in patients infected with COVID-19. Statins have been proposed to have beneficial effects in patients infected with MERS-COV, another coronavirus similar to COVID-19, but there have been no randomized studies supporting the use of statins in patients with COVID-19 infection. In this project we propose the combined use of one of these drugs, ruxolitinib with simvastatin, looking for a synergistic effect in the inhibition of viral entry and in the anti-inflammatory effect.
There is currently no treatment available for COVID-19, the acute respiratory illness caused by the novel SAR-CoV-2. Convalescent plasma from patients who have recovered from COVID-19 that contains antibodies to the virus is a potential therapy. On March 25th, 2020, the FDA approved the use of convalescent plasma under the emergency investigational new drug (eIND) category. Randomized trials are needed to determine the efficacy and safety of COVID-19 convalescent plasma for acute COVID-19 infection. The objective of the CONCOR-1 trial is to determine the efficacy of transfusion of COVID-19 convalescent plasma to adult patients admitted to hospital with COVID-19 infection at decreasing the frequency of in-hospital mortality in patients hospitalized for COVID-19. It is hypothesized that treating hospitalized COVID-19 patients with convalescent plasma early in their clinical course will reduce the risk of death, and that other outcomes will be improved including risk of intubation, and length of ICU and hospital stay. This pan-Canadian clinical trial has the potential to improve patient outcomes and reduce the burden on health care resources including reducing the need for ICU beds and ventilators.
This study is a phase II, parallel, prospective, randomized, double-blind, placebo controlled trial. The present study will aim to address the efficacy and safety of acute administration of triiodothyronine on ICU patients diagnosed with pulmonary infection due to COVID-19 and require mechanical respiratory support or ECMO.
This is a single center, randomized, double-blind, placebo-controlled, exploratory phase II study enrolling 60 patients. We propose the administration of a blinded dose of an investigational product (IP) (clazakizumab or placebo [0.9% saline]) in patients with COVID-19 disease and signs of pulmonary involvement who have not yet required mechanical ventilation and/or extracorporeal membrane oxygenation (ECMO). If a patient progresses to mechanical ventilation and/or ECMO or develops clinical signs of deteriorating COVID-19 disease, and there are no treatment related serious adverse events (SAEs), within the initial 14 day period after the first dose of the IP, at the discretion of the investigator or treating physician, open-label clazakizumab 25mg IV x 1 dose may be administered. A minimum of 24 hours should elapse between the first dose of IP and this dose of open-label clazakizumab. The patient will remain blinded as to the identity of the IP administered in the first dose.
This is an exploratory study to evaluate the efficacy of hydroxychloroquine (400 mg BID on D1 and 400 mg/day on D2 to D7) and azithromycin (500 mg/ 5 days) to treat mild ambulatory COVID-19 patients.
The investigational medicinal product consists of expanded allogeneic mesenchymal stromal cells derived from adipose tissue and administered intravenously. The objective of this project is to evaluate the safety and efficacy of the administration of expanded allogeneic adipose tissue adult mesenchymal stem cells, in patients infected with SARS-COV-2 with COVID-19 type complications.
The study is configured as a retrospective and prospective observational study. The study will be multi-center and will involve all COVID-19 pneumonia patients treated with canakinumab administered subcutaneously.
Hope Biosciences is conducting a research study of an investigational product called allogeneic adipose-derived mesenchymal stem cells (abbreviated as HB-adMSCs) to provide immune support against COVID-19. The study purpose is to evaluate the safety and efficacy of five IV infusions of HB-adMSCs in subjects with no signs of COVID-19.
The 2019-20 coronavirus disease, caused by COVID-19, is an ongoing pandemic. The measures in which public health officials quarantine confirmed and isolate symptomatic cases in order to reduce the spread COVID-19 is the common practice used in most countries. However, a significant question remains in regards to the asymptomatically infected individuals, which may propagate the virus and impede infection control. The other question to consider is whether these asymptomatic carriers develop an immune response or continue viral shedding. The purpose of the current study is the evaluate the immune response, i.e developing anti-SARS-CoV-2 antibodies in the asymptomatic cases, in a household study design. We plan to evaluate over 1000 patients with positive COVID-19 results and their households.
This is a proof of concept study to evaluate the efficacy of nitazoxanide (600 mg BID) to treat hospitalized patients with moderate COVID-19.
