Active clinical trials for "COVID-19"

This open label randomized controlled multicenter phase II trial will evaluate the clinical impact of the use of HFNC vs. conventional oxygen therapy in patients with moderate and severe hypoxemic acute respiratory failure secondary to SARS-CoV-2 infection.

SARS-CoV-2 is the agent responsible for a new infectious respiratory disease called Covid-19 (for CoronaVirus Disease 2019) which is mainly characterized by potentially severe and fatal lung damage. The severity of the clinical signs associated with this pathology requires the admission to hospital of approximately 20% of patients, 5%-10% of whom will be admitted to intensive care. The most severe cases of this pathology begin with dyspnea which worsens rapidly around the 7th-10th day of the disease into an acute respiratory distress syndrome (ARDS) which requires the patient to be put under mechanical ventilation in the intensive care unit and is responsible for the majority of deaths. Certain biological parameters suggest a massive and brutal release of cytokines (interleukins IL-6, IL-8 and IL-10 mainly) secondary to a syndrome of macrophagic activation mainly in the pulmonary level. Several therapeutic trials aimed at reducing or controlling this immune storm are in progress (anti IL-6 antibodies, anti r IL6 Ab, corticosteroids). Molecular hydrogen acts on the final path of this complex inflammatory cascade by inhibiting the cellular action of reactive oxygen species. Its early use combined with nasal oxygen therapy could prevent this worsening of the respiratory system, so could be likely to limit the risk of overflow of intensive care services during the pandemic and save lives. The aim of this study is to evaluate the safety and the Dose Limiting Toxicity (DLT) of hydrogen therapy delivered by a nasal cannula in addition to conventional oxygen therapy in patients with moderate Covid-19

There is an immediate need for population-level intervention research to address the impacts of the coronavirus disease 2019 (COVID-19) pandemic and its containment measures on mental health and substance use (MHSU). While online programs are available to address these issues, they are often delivered in an asynchronous format with relatively low therapist or health coaching guidance. As highlighted by a recent systematic review, positive outcomes for online mental health programs are tied to the intensity of therapist or coaching guidance, which increases cost and reduces population access to more effective online options. A way to offset cost while maintaining effectiveness is to offer MHSU programs to groups online, rather than individually. In 2019, the investigators launched an RCT to test gender-stratified group interventions to address MHSU among community-based Indigenous and non-Indigenous adults in southern Alberta. The investigators implemented the interventions with more than 200 adults before the study was paused due to COVID-19.

The primary objective of this study is to evaluate the time to confirmed clinical recovery in participants hospitalized with COVID-19. Candidate agents will be evaluated frequently for efficacy and safety, with candidate agents being added to and/or removed from the study on an ongoing basis, depending on the results of their evaluation.

This study is being conducted in two parts, A and B. Part A is a randomized, double-blind, parallel arm study to evaluate the safety and efficacy of LYT-100 compared to placebo in adults with post-acute COVID-19 respiratory complications. Part B is an Open Label Extension (OLE) study for patients who complete Part A.

The overall objective of this study is to efficiently evaluate the clinical efficacy and safety of different investigational therapeutics among adults who have COVID-19 but are not yet sick enough to require hospitalization. The overall hypothesis is that through an adaptive trial design, potential effective therapies (single and combination) may be identified for this group of patients. COVID-19 Outpatient Pragmatic Platform Study (COPPS) is a pragmatic platform protocol designed to evaluate COVID-19 treatments by assessing their ability to reduce viral shedding (Viral Domain) or improve clinical outcomes (Clinical Domain). To be included into the platform, every investigational product will collect data for both Domain primary endpoints. Individual treatments to be evaluated in the platform will be described in separate sub-protocols.

The aim of this unblinded parallel-group randomized multicenter clinical trial is to compare the clinical effectiveness of high flow nasal therapy (HFNT) with conventional oxygen therapy (COT) in patients with confirmed COVID-19 related acute hypoxemic respiratory failure.

A randomized, open label, two arm, pilot trial of Pirfenidone 2,403 mg administered per nasogastric tube or orally as 801mg TID for 4 weeks in addition to Standard of Care (SoC), compared to SoC alone, in a population of COVID-19 induced severe ARDS. Patients will be randomized according to 1:1 ratio to one of the trial arms: Pirfenidone (intervention arm) or SoC (control arm).

Convalescent plasma has been shown to be safe and effective for treatment of several diseases. Preliminary data indicate that it is safe for treatment of COVID-19. We found that viremia upon admission identifies patients at 7 fold increased risk of admission to intensive care and 8 fold increased risk of death. CP treatment appeared to result in rapid viral clearance in a small case series. CP appeared to be well tolerated in a phase I study in which patients only received one dose of CP and a phase II study in which CP was given until viremia disappeared (unpublished data). Randomised controlled studies assessing the efficacy of CP are lacking and thus the efficacy of CP is unknown. Preliminary data indicate that treatment should be given early, prior to development of severe illness. Detection of viremia upon admission identifies a group at high risk of severe disease and death that has the most to benefit from CP. Phase II study data indicates that treatment should be given until SARS-CoV-2 is no longer detected in serum and the donor antibody neutralization titres should be ≥1/640. A randomised controlled trial in which viremic patients are treated with CP with the equivalent of an antibody titre ≥1/640 is thus required to determine if CP can be an effective COVID-19 treatment.
