Active clinical trials for "Severe Acute Respiratory Syndrome"

Noble metals such as gold and silver have been appreciated for millennia not only for their beauty but also for their ability to fight diseases. Silver nanoparticles (AgNPs) have been employed as chemical drugs thanks to their unique physiochemical and chemical properties as well as biological features, such as anti-inflammatory, anti-angiogenesis, antiplatelet, antifungal, anti-cancer and antibacterial activities I

The coronavirus disease (COVID-19) epidemic represents a major therapeutic challenge. The highly contagious severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) and the long duration of the disease have led to a massive influx of patients admitted in health services and intensive care units. According to current knowledge, there are no treatments that prevent the spread of the infection, especially in exposed populations, or the disease progression to a severe form. Daily active smokers are infrequent among outpatients or hospitalized patients with COVID-19. Several arguments suggest that nicotine is responsible for this protective effect via the nicotinic acetylcholine receptor (nAChR). Nicotine may inhibit the penetration and spread of the virus and have a prophylactic effect in COVID-19 infection. However, the epidemic is progressing throughout French territory and new variants (in particular the "English B1. 1.7 variant of SARS-COV-2") much more contagious run a risk of accelerating the epidemic in the population. The anti-SARS-COV-2 vaccines recently launched (or being evaluated) represent great hope in this health crisis, but trials were only able to show their effectiveness on symptomatic forms of SARS-COV-2 infection. On the one hand, the vaccination compaign for the entire population requires many months,which leaves many unprotected subjects waiting. In addition, there is currently no evidence of a protective role of vaccines against asymptomatic forms of COVID-19 and therefore on SARS-COV-2 transmission. Finally, the nicotine patches may protect people in hight-risk areas/periods until they are vaccinated (if they accept it and are eligible for it) and in the post-vaccination weeks necessary for the effectiveness of the vaccine,which reinforces the importance of evaluating this alternative prevention strategy, in the context of the arrival of vaccines

The study aims to examine whether the combination of Lopinavir/Ritonavir plus Ribavirin for treatment of severe acute respiratory syndrome (SARS) is superior to placebo.

A prospective, randomized, placebo-controlled, double-blinded, phase III clinical trial of the therapeutic use of convalescent plasma in the treatment of patients with moderate to severe COVID-19

To compare various treatments provided to positive COVID-19 patients at locations across the OSF Ministry. Provide the opportunity to compare the effectiveness of various treatments and treatment timelines provided to specific cohorts of patients that have the potential to impact future treatment plans for COVID-19 patients and/or future research hypotheses.

In this trial patients will be treated with either a combination of therapies to treat COVID-19 or a placebo. Treatment will last 10 days, and patients will be followed for 6 months.

The COVID-19 pandemic has been characterized by high morbidity and mortality, especially in certain subgroups of patients. To date, no treatment has been shown to be effective in controlling this disease in hospitalized patients with moderate and / or severe cases of this disease. Hydroxychloroquine and lopinavir / ritonavir have been shown to inhibit SARS-CoV viral replication in experimental severe acute respiratory symptoms models and have similar activity against SARS-CoV2. Although widely used in studies of critically ill patients, to date, no study has demonstrated its role on the treatment of high-risk, newly diagnosed patients with COVID-19 and mild symptoms.

Many non-invasive ventilatory choices are available for COVID-19 patient who are having mild to moderate respiratory distress and their use will decrease the chance of ICU admission, intubation and mechanical ventilation in severe cases of COVID-19. However, all these respiratory supports and oxygen supply devices are aerosol generating and their selection should be precised enough to control nosocomial spread. High flow nasal cannula HFNC is a device that delivered the warmed and humid air on high flow rate through nose. It is used to treat severe respiratory distress in COVID-19 patients, a non-invasive ventilatory approach which is relative comfortable by using humidified and pre-heated air containing large concentration of oxygen. In acute respiratory failure HFNC is proven to be very effective and it also reduced the need of mechanical ventilation in severe patients. Apart from the supply of oxygen, HFNC generating positive airway pressure and decreasing the rebreathing from anatomical dead space. Prone position is also a save therapy and has been proven to be effective for refractory hypoxia by increasing tidal volume, oxygenation and diaphragmatic functions in ARDS patients. Recent studies showed that prone positioning and HFNC might avoid the prerequisite of intubation in moderate to severe patients of ARDS and as a result it decreases the nosocomial infection in physicians who are doing these aerosol generating procedures.

Administration of Zinc and resveratrol or double placebo for a period of 5 days and will be monitored for a 14 day period in covid-19 positive patients in an outpatient setting

VIDO has developed a vaccine called COVAC-1. The study vaccine contains a portion of the SARS-CoV-2 spike protein, called S1. The spike protein is the part of the virus that is responsible for attaching to the surface of host cells. COVAC-1 contains an adjuvant called TriAdj. An adjuvant is a compound that is added to a vaccine to help the vaccine produce a better immune response. The TriAdj adjuvant is made up of three components (a toll-like receptor agonist polyI:C, an immunostimulatory host defense protein HDP IDR-1002 and a polyphosphazene carrier system, PCEP). The three components work together to improve the body's response to the S1 protein. The COVAC-1 vaccine is expected to stimulate the body to make antibodies against the S1 protein. The antibodies will recognize the viral spike protein if the body is exposed to the virus and prevent or reduce the severity of COVID-19 illness. In animal studies, the immune response generated by the COVAC-1 vaccine was able to protect the vaccinated animals against a severe SARS-CoV-2 infection. Phase 1 is a multi-centred, multi-national trial of the COVAC-1 vaccine to be completed in Canada and Brazil. It will be a randomized, observer-blinded, and placebo-controlled study to assess the safety and immunogenicity of two dosing levels (25 and 50 µg S1 protein) administered twice (4 weeks apart) in healthy adults 18 through 54 years of age (Arm 1a) and 55 years of age and older (Arm 1b). Enrolment and vaccination of participants will be staggered over time based on vaccine dose. Study participants aged 18 to 54 and those >55 years of age will commence in parallel at the starting dose of 25 ug and after approval by Sponsor based upon recommendations from the Data Safety Monitoring Board (DSMB), new study participants will be allowed to receive the higher dose of 50 ug. Approval will also be sought from Sponsor, based on recommendations provided by the DSMB, to proceed with the second dose in each dosing and age group. Within the same age group, the 8 participants receiving the lower dose are randomized with 4 participants receiving placebo and the 8 participants receiving the highest dose are randomized with 4 participants receiving placebo. Within each dose level of 12 participants, it is proposed to immunize a first cohort of 3 participants (including at least 2 active vaccine participants) and pending no holding rule is met after 48 hours, as determined by the 48-hour-post-dose 1 phone call, to immunize the remaining 9 participants within that dose level. Every attempt will be made to fully enroll all age groups.
