Filter by:The primary objective of this study is to evaluate the effectiveness of tetrandrine tablets in preventing the progression of COVID-19 from severe to critical.
A randomized, double-Blind, placebo-controlled trial aimed to investigate the safety and efficacy of sivelestat on treating adult patients with COVID-19-related acute respiratory distress syndrome (ARDS)
The aim of the study is to investigate the safety and immunogenicity of a two-component intranasal vaccine for the prevention of COVID-19 in healthy volunteers 18-60 years old
The main aim is to determine whether vitamin C can reduce 28-day all-cause mortality or persistent organ dysfunction compared with placebo in patients with severe and critical ill COVID-19 patients. Participants will randomly receive HIVC or placebo for 4 days once enrolled. The primary outcome is a composite of death or persistent organ dysfunction (defined as dependency on vasopressors, mechanical ventilation, or CRRT) at day 28 after randomization.
This phase II trial studies low-dose radiation therapy as a treatment for patients with severe COVID-19 pneumonia to improve clinical status.
VIDO has developed a vaccine called COVAC-1. The COVAC-1 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 a TriAdj adjuvant. An adjuvant is a compound that is added to a vaccine to help the vaccine produce a better immune response. The 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 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. The COVAC-005 Study is a Phase I, multi-centre trial of a SARS-CoV-2 vaccine booster. This is a randomized, observer-blinded, and placebo-controlled study to assess the safety and immunogenicity of COVAC-1 booster dose administered once in generally healthy adults 18-65 years of age who have received a minimum of 2 doses of an authorized COVID-19 vaccine at least 4 months prior to Day 0. The study will follow a dose-escalation design to test the safety and immunogenicity of three dosage levels (10, 25 and 50 µg). In each dose escalation group participants will be randomized in a 3:1 ratio, to receive either the investigational product or a placebo, respectively. Stratification will be according to the Investigational product dose received. Sub-analysis will be completed in two age groups, 18-54 and 55-65 years. Study participants will be initially randomized to the lowest dose of 10 µg or placebo. After approval by the Sponsor and based on the recommendations from the DSMB following the Day 7 safety analysis, new study participants will be allowed to be randomized in the higher dose escalation group of 25 µg. Approval will also be sought from the Sponsor, based upon the DSMB recommendation, to proceed with the higher dose of 50 µg. Within each dose escalation group of 16 participants (12 active vaccine recipients, and 4 placebo recipients) it is proposed to randomize a first cohort of 4 participants, including at least 3 active vaccine recipients, and pending no holding rule is met after 48 hours, as determined by the post-injection phone call, the remaining 12 participants within that dose escalation group will be randomized.
The purpose of this waitlist-controlled, single-blind, one-way crossover, pilot trial is to evaluate the potential effects of ~8 weeks of chiropractic care on patient-reported fatigue and the autonomic nervous system in adults with long COVID. This study will allow us to estimate the standard deviation of the primary endpoint in our population with which a formal power calculation for a future randomized, controlled trial can be performed.
Prone position ventilation was used 220 times in 44 out of 68 patients with severe COVID-19 induced ARDS treated with VV-ECMO. PPV treated patients did not benefit from PPV and the incidence of PPV related adverse events was high
At present, China is facing the first wave of COVID-19 epidemic after the liberalization. The infection rate has exceeded 50% in most areas, and even exceeded 80% in some cities. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) belongs to the beta genus of coronavirus and enters cells mainly by binding angiotensin converting enzyme 2 (ACE-2) to the spike protein on the envelope. The Omicron strain is the main epidemic strain at present. The transmission ability of Omicron strain is stronger than Delta strain, but the pathogenicity is weakened. At present, the published articles on the adjuvant treatment of COVID-19 with acupuncture are mostly theoretical discussions or case reports, and randomized controlled trials on the observation of curative effect are rare. The purpose of this study is to clarify the effectiveness of the adjuvant treatment of COVID-19 with acupuncture. Providing high-level research evidence for them.
In this trial the researchers plan to recruit 4,000 volunteers to be randomly allocated either wearing face masks in public spaces where they are close to other people, or not wear face masks in such circumstances. For each participant the trial period is 2 weeks, after which they will be asked to complete a brief questionnaire which includes questions about whether they experienced the common cold, influenzas or COVID-19 symptoms during the trail period.
