NCT ID: NCT04878042 Withdrawn - COVID-19 Clinical Trials

COVID-19 Infection Control Using H2O2 Mouth Wash and Nasal Spray

Start date: April 9, 2021
Phase: N/A
Study type: Interventional

Hydrogen peroxide is produced physiologically by oral bacteria and plays a significant role in the balance of oral microecology since it is an important antimicrobial agent. In the epithelial cells, the enzyme superoxide dismutase catalyzes a reaction leading from hydrogen peroxide to the ion superoxide. The induced oxidative stress stimulates a local innate response via activation of the toll-like receptors and the NF-κB. Those kinds of reactions are also activated by viral infections. Virus-induced oxidative stress plays an important role in the regulation of the host immune system and the specific oxidant-sensitive pathway is one of the effective strategies against viral infections. Therefore, nose/mouth/throat washing with hydrogen peroxide may enhance those local innate responses to viral infections. The investigators hypothesised that a treatment with a mouth wash and a nasal spray containing a diluted solution of hydrogen peroxide may accelerate the negativisation rate of a positive PCR swab test for SARS-CoV-2 (COVID-19).

NCT ID: NCT04874805 Withdrawn - Covid-19 Clinical Trials

Oxygen Saturation: Analytical Comparison for COVID

SHOCOVID
Start date: May 2, 2022
Phase: N/A
Study type: Interventional

In many patients, respiratory Sars-Cov2 infection causes arterial hypoxemia, which remains without signs of verbalized respiratory distress, up to a point. This phenomenon, called "happy" or "silent" hypoxemia, has a plural pathophysiological basis. Hypoxemia has been shown to be predictively associated with admission to the ICU. Therefore, the question of constant monitoring of oxygenation, practiced on a large scale, at home, in asymptomatic patients or contact cases, arises. A large number of portable pulse oximeter are currently freely available on the market; however, their clinical validation remains sometimes doubtful, or even absent from FDA standards. The objective of this study is to evaluate the accuracy of SpO2 values provided by portable pulse oximeter in COVID patients, in comparison with the reference method. The study will be conducted on a population of adult patients with COVID, hospitalized in the ICU, for whom gasometry sampling is already scheduled in the usual management.

Pilot Study to Evaluate the Safety, Tolerability, and Efficacy of 5-ALA-Phosphate + SFC as an Immune System Enhancer Along With Vaccination Against COVID-19

Phase: N/A
Study type: Interventional

This is an open-label, two arm interventional exploratory study to evaluate the safety and efficacy of 5-ALA-Phosphate-SFC during the vaccination of subjects against SARS-CoV-2 (COVID-19) virus infection to define the safety and to activate the immune system during SARS-CoV-2 vaccination. The primary objective of this study is to determine the safety of a 4 week daily oral administration of 5-ALA-Phosphate + SFC in subjects vaccinated with COVID-19 Vaccine

Start date: December 16, 2021
Phase: Phase 3
Study type: Interventional

This clinical trial aims to ascertain the impact of GSE and Xylitol (XLEAR) in decreasing the time of negativisation in PCR testing in patients with COVID-19.

NCT ID: NCT04848467 Withdrawn - Clinical trials for SARS-CoV-2 Infection

COVID-19: A Trial Studying the SARS-CoV-2 mRNA Vaccine CVnCoV to Learn About the Immune Response, the Safety, and the Degree of Typical Vaccination Reactions When CVnCoV is Given at the Same Time as a Flu Vaccine Compared to When the Vaccines Are Separately Given in Adults 60 Years of Age and Older

CV-NCOV-011
Start date: October 1, 2021
Phase: Phase 3
Study type: Interventional

The most recently discovered coronavirus (SARS-CoV-2) may cause illness in humans ranging from the common cold to serious illness, also referred to as Coronavirus disease 2019 (COVID-19). As of January 2021, there are only few authorized vaccines available for the prevention of COVID-19. "CVnCoV" is a new SARS-CoV-2 messenger ribonucleic acid (mRNA) vaccine which is currently being developed for the prevention of COVID-19. The vaccine contains a molecule called mRNA which serves as an instruction manual for the cells in the body to produce a piece of protein from SARS-CoV-2 which activates the body´s defense system. The "CVnCoV" vaccine is injected into the muscle. After the injection, the body recognizes the protein as something that does not belong there. In this way the natural infection with the virus is imitated. The body activates immune cells to produce antibodies against the virus and creates specific immune cells called T cells. "CVnCoV" is given in two doses separated by 28 days. In this study, the researchers will look at how well "CVnCoV" works when the first of the two doses is given together with a flu vaccine called seasonal quadrivalent influenza vaccine (QIV). They will also look at how well the flu vaccine works under these conditions. The QIV is injected into the muscle and is given as 1 dose. To see how well the participants' immune systems is activated by "CVnCoV" and QIV, the researches will measure the levels of specific antibodies against the viruses in the blood. Antibodies are proteins that allow the immune system to find and react to bacteria and viruses in the body. The researches will look into how safe the vaccination is and which type and degree of typical vaccination reactions are seen. To give "CVnCoV" and the flu vaccine together in the future when needed, e.g. during the flu season, would reduce the burden on the health system and on the patients. Participants in this study are adults aged 60 years and older. In this study, participants are assigned to one of the two parallel groups of the same size. The assignment to either group is done by chance via a computer program. Participants in group 1 (Co-ad group) will receive CVnCoV at the same visit as QIV. Participants in group 2 (control group) will receive QIV and CVnCoV at two different visits. The Co-ad group will receive the first dose of CVnCoV and a dose of QIV in opposite arms at Day 1, the second dose of CVnCoV at Day 29, and a placebo injection, i.e. an injection that looks like a vaccination injection but does not contain vaccine, at Day 57. The control group will receive QIV and placebo in opposite arms at Day 1, the first dose of CVnCoV at day 29 and the second dose of CVnCoV at Day 57. There will be five visits and four phone calls. During the study, the study team will take blood samples on four occasions to measure the antibodies against SARS-CoV-2, and nasopharyngeal swabs at 1 occasion. The physicians will do physical examinations at each visit. The participants will be asked how they are feeling and if they have any medical problems. They will, in addition, receive an electronic Diary to report medical problems.
