NCT05445479
A new coronavirus, the third documented animal-to-human passage, emerged in Wuhan , China in the last quarter of 2019. Acne patients on doxycycline escaped seasonal viruses, showing the interest of this antibiotic as a possible treatment against COVID-19. The antiviral action of tetracyclines can be explained by different mechanisms. First of all, tetracyclines are modulators of innate immunity by decreasing NF-B expression, inhibiting inflammatory cytokines such as TNF-α, IL-1β and IL-6, inflammatory granulomas and free radical release . This action is obtained at doses lower than those necessary to obtain an antibiotic effect. Another possible action of tetracyclines is their ability to chelate zinc from matrix metalloproteinases (MMPS). The coronavirus family is known to bind to host MMPs, particularly for viral survival. Their chelating activity may help inhibit SARS-CoV-2 infection by limiting its ability to replicate in the host. Finally, tetracyclines could have a direct action by inhibiting the replication of single-stranded RNA virus, such as the SARS-CoV-2 coronavirus.We therefore propose a larger comparative study using data from the French National Health Data System.
NCT04359511
To date, there is no efficient therapeutics to prevent or treat COVID-19 related pulmonary failure. Corticosteroids (CS) could be a helpful therapeutic. Retrospective reports suggested survival improvement in patients with acute respiratory distress syndrome (ARDS). CT scan for COVID19 hospitalized patients showed sometimes unusual aspects of pneumonia, suggestive of an organizing phase of diffuse alveolar damage (DAD). We hypothesize that, in the context of alveolar aggression induced by COVID-19, CT scan could help to individualize patients with a high probability of pulmonary organizing process who could benefit from CS treatment.
NCT04910269
The primary objective of the Outpatient Treatment with Anti-Coronavirus Immunoglobulin (OTAC) (INSIGHT 012) trial is to compare the safety and efficacy of a single infusion of anti-COVID-19 hyperimmune intravenous immunoglobulin (hIVIG) versus placebo among adults with recently diagnosed severe acute respiratory syndrome - coronavirus 2 (SARS-CoV2) infection who do not require hospitalization. The primary endpoint of this double-blind randomized trial is a five-category ordinal outcome that assesses the participant's clinical status seven days after the infusion of hIVIG or placebo. 1. Asymptomatic and no limitations in usual activity due to COVID-19 2. Mild COVID-19 illness or minor limitations to usual activity 3. Moderate COVID-19 illness and with major limitations to usual activity 4. Severe COVID-19 or serious disease manifestation from COVID-19 5. Critical illness from COVID-19 or Death Two strata of participants will be identified for analysis purposes. Stratum 2 will be participants who receive direct-acting antivirals (DAAs) or other anti-SARS-CoV2 agents that are approved/available and recommended for use as part of standard of care (SOC), estimated to be about 20% of participants. Stratum 1 will be participants who do not receive this agents, estimated to be about 80% of participants.
