Active clinical trials for "COVID-19"

This study is designed as a multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the clinical efficacy and safety of MW33 injection in patients with mild or moderate COVID-19, and to evaluate its pharmacokinetic profile and immunogenicity.

Coronavirus Disease 19 (COVID-19) is a worldwide pandemic and a major global health concern which is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). The newly emerged Coronavirus disease 2019 (COVID-19), which was first identified in Wuhan, China, has swept through 219 countries, killing a staggering number of people. According to WHO reports, the number of deaths had risen to 3,155,168by March 30, 2021, out of 149,910,744 confirmed cases. In Bangladesh, the outbreak has infected over 745,322confirmed cases, with over 11,053 deaths reported. Though the patient may be asymptomatic or present with mild symptoms, mortality is quite high in the severe form of the disease which often progresses to critical phase presented as Acute Respiratory Distress Syndrome (ARDS). This is due to exaggerated response of immune system to the virus termed as cytokine storm syndrome (CSS). There is currently no effective antiviral therapy for SARS-CoV-2 and supportive care is the mainstay of therapy. As a result we are still searching for a better therapeutic agent which will help in treating Covid-19 cases in terms of mortality, morbidity, oxygen requirement, length of stay in hospital. Co-trimoxazole (composed of one-part Trimethoprim and five parts Sulfamethoxazole)is a sulphur containing anti-folate bactericidal drug which is being used for over 60 years for various indications esp. respiratory tract infections. It is known to have immunomodulatory and anti-inflammatory properties that may help to prevent progression to critical phase and cytokine storm syndrome in severe COVID-19 patients. It acts rapidly when given in high dose due to its better bioavailability and lung penetration. Low cost and a good safety profile can make it an ideal candidate for treatment of COVID -19 in a low resource country like Bangladesh. Methods and materials: This interventional double-blind place controlled randomized trial will be conducted in the department of medicine at Bangabandhu Sheikh Mujib Medical University (BSMMU) for a duration of 6 months following approval of this protocol. It will recruit at least 94 consecutive adults (18 years or older) patients with clinically suspected COVID-19 and severe illness as per WHO criteria. After taking informed written consent patients will be randomly assigned in a 1:1 ratio to either oral high dose co-trimoxazole in addition to standard therapy or placebo along with standard therapy. Baseline characteristics, changes in the physiological and biochemical parameters like (SpO2/FiO2 ratio, respiratory rate, body temperature and C - reactive protein), length of hospital stay, side effects of drugs, requirement for ventilatory support (non-invasive and invasive ventilation) and 28- day mortality between the two groups will be compared. Data will be collected from case record forms, anonymised and stored securely in a secure online web based portal. Statistical analysis will be performed using t-test or Mann -Whitney U test or Wilcoxon signed rank test for continuous variables and Chi- square test or Fisher's exact test for categorical variables. Survival will be assessed by the Kaplan-Meier method. Comparisons between two groups will be performed using the log-rank test. A p-value of < 0.05 will be considered to be significant. The statistical software SPSS version 25 will be used for the analysis. Conclusion If the results from this clinical trial demonstrate the beneficial effects of high co-trimoxazole in patients with severe COVID-19 it could help to reduce the need for respiratory support for thousands of patients, saving valuable lives and decrease the burden of healthcare system in countries with limited resources.

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which originated in Wuhan, China, has become a major concern all over the world. Convalescent plasma or immunoglobulins have been used as a last resort to improve the survival rate of patients with SARS whose condition continued to deteriorate despite treatment with pulsed methylprednisolone. Moreover, several studies showed a shorter hospital stay and lower mortality in patients treated with convalescent plasma than those who were not treated with convalescent plasma. Evidence shows that convalescent plasma from patients who have recovered from viral infections can be used effectively as a treatment of patients with active disease. To date, no specific treatment has been proven to be effective. The investigators plan to treat critical Covid-19 patients with hyperimmune plasma.

The investigators propose a prospective, randomized, double-blind, placebo-controlled study, conducted in two phases. The purpose of the study is to evaluate the safety and efficacy of methotrexate in a cholesterol-rich non-protein nanoparticle (MTX -LDE) in adults diagnosed with mild Coronavirus-19(COVID-19) disease. A total of 100 patients will be randomized to receive MTX-LDE or placebo each 7 days, up to 3 times, during in hospital treatment.

This 3-arm study compares the effectiveness of an (1) 8-week mindfulness-based intervention, MBCT-R (Mindfulness-Based Cognitive Therapy for Resilience During COVID-19)+CHA MindWell vs. (2) iCBT (internet based Cognitive Behavioral Therapy)+ CHA MindWell vs. (3) CHA MindWell remote monitoring and telephone coaching alone on depressive symptoms as measured over the course of 24-weeks by the computerized adaptive mental health (CAT-MH) interview for depression (CAT-DI). Secondary outcomes include rates and levels of alcohol and drug use, as well as the number of required mental health clinician visits (televisits and in-person visits). Exploratory outcomes include stress-related affect reactivity and salivary inflammatory markers (e.g., interleukin-6).

The main objective of the study is to evaluate the capacity of a novel nutritional supplement intervention including strains from the species Bifidobacterium longum, Bifidobacterium animalis subsp. Lactis and Lactobacillus rhamnosus, plus vitamin D, zinc and seleniumt) (immune system enhancer, antioxidant and anti-inflammatory capacity) to decrease the viral load by nasopharyngeal smear in patients admitted for COVID-19 coronavirus disease.

The pandemic caused by SARS-CoV-2 is a global emergency present in 6 continents including 66 countries, incurring a shortage of effective and safe therapeutic alternatives that can contribute to reducing the risk of contamination, as well as helping to reduce the viral load of the positive patient. This requires a coordinated, effective and immediate action on the part of governments, companies, academic entities and even at the individual level. In the search for new therapeutic and prevention alternatives, the application of hypochlorous acid (HClO) to the nasal mucosa is proposed, a broad-spectrum and fast-acting antimicrobial solution, whose safety has been proven in preclinical trials. The efficacy of HClO has been tested against enveloped and non-enveloped viruses, reducing virus particles without affecting human cells. This solution could contribute to reducing the viral load and the risk of contamination of patients and professionals. This could have an impact on controlling the COVID-19 pandemic.

Assessment of the Effectiveness of Niclosamide as Add on Therapy to the Standard of care Measures in COVID-19 Management in a randomized controlled clinical trial

Severe Covid-19 (Coronavirus Disease 2019) infections generate major but inappropriate production of cytokines and, in some cases, generate anti-IFN (Interferon) auto-antibodies, inducing acute respiratory distress syndrom (ARDS). Therapeutic plasma exchange (TPE) have been reported to be efficient for improving the hyperinflammatory condition state and the respiratory function, which has been described in case reports or small series. The study aims to remove cytokines during cytokine storm and anti-IFN auto-antibodies (when present) to prevent developpement of an inappropriate immune response and to improve the clinical response to reanimation treatment, in particular the respiratory parameters leading to a rapid improvement of clinical status. To that aim, the study investigates to compare a treatment using TPE plus usual treatments in intensive care unit (experimental arm) versus usual treatments in intensive care unit (routine arm) in a randomised trial.

This is a phase Ⅱb, single-center, randomized, double-blind, placebo-controlled study, to evaluate the immunogenicity and safety of the recombinant COVID-19 vaccine (Sf9 cells) in the subjects from healthy adults and elderly adults aged 18 years and above (aged 18-59 and 60-85 years) with immunization procedures 0, 21, 42 days and doses 40μg.
