Phase 2b/3 Trial of VSV-ΔG SARS-CoV-2 Vaccine (BRILIFE) Against Approved Comparator Vaccine.

BRILIFE002
Start date: September 30, 2021
Phase: Phase 2/Phase 3
Study type: Interventional

IIBR-100 (VSV-ΔG) is a self-propagating live virus vaccine that contains the spike protein of the Wuhan wild-type SARS-CoV-2 virus. Preclinical and phase 1/2 trials have demonstrated no safety signals of concern and have further demonstrated immunologic response that approximates the response seen in convalescent individuals. The purpose of this phase 2b/3 trial is to document the non-inferiority of IIBR-100 vs. an already-approved vaccine for COVID-19.

NCT ID: NCT04983446 Withdrawn - Covid19 Clinical Trials

In-patient COVID-19 Study of Intranasal Foralumab

Start date: April 30, 2022
Phase: Phase 2
Study type: Interventional

This is a Phase 2, randomized, placebo-controlled, double-blind, proof-of-concept study of intranasal foralumab in hospitalized subjects with severe COVID-19 and pulmonary inflammation. Foralumab is a fully human second generation anti-CD3 mAb with a modified Fc unit (two amino acid substitutions) composed of 2 heavy chains with an immunoglobulin (Ig) G1constant region and 2 light chains with a kappa constant region. In a separate Phase 2 randomized, controlled, pilot trial conducted to assess safety, tolerability, and efficacy in 39 patients with mild to moderate COVID-19 in Brazil, showed that intranasal foralumab may be of benefit in modulating immune reactivity and in reducing pulmonary inflammation. Importantly, intranasal administration of foralumab was well tolerated with no clinically significant changes in blood cell counts (including blood lymphocytes), no evidence of hypersensitivity, and no serious adverse events (SAEs) were reported in the study.

NCT ID: NCT04970719 Withdrawn - COVID-19 Pneumonia Clinical Trials

Baricitinib in Hospitalized Covid-19 Patients With Diabetes Mellitus

Start date: July 10, 2021
Phase: Phase 3
Study type: Interventional

To date, some of the most promising drugs used in the treatment of COVID pneumonia are systemic corticosteroids, remdesivir and baricitinib. Dexamethasone has been found efficacious in reducing mortality in patients requiring supplemental oxygen and mechanical ventilation. There is a trend towards reduced mortality in patients who receive remdesivir and dexamethasone combination, supporting the hypothesis that an antiviral drug combined with an anti-inflammatory agent improve outcomes in COVID-19. Baricitinib plus remdesivir is superior to remdesivir alone in reducing recovery time and accelerating improvement in clinical status among patients with COVID-19, notably among those receiving high-flow oxygen non-invasive ventilation. Diabetes mellitus increases the risk for COVID-19 morbidity and mortality. Patients with diabetes have coexisting morbidities and already immune-compromised. Steroids cause further immunosuppression and may contribute to uncontrolled blood glucose in this group of patients, resulting in worse outcomes. Baricitinib can be an alternative to corticosteroids in diabetic patients. This open-label multi-centre non-inferiority randomized controlled trial will be conducted in seven hospitals in Bangladesh. The primary objective is to evaluate the clinical efficacy of baricitinib plus remdesivir compared to dexamethasone plus remdesivir in hospitalized COVID-19 patients with diabetes mellitus, as assessed by the proportion of patients, need "rescue treatment" between two groups by day 29. Hospitalized adult (≥18 years) diabetic patients with confirmed SARS-CoV-2 infection have ordinal scale category 5 will be included in the study. Subjects will be randomized in a 1:1 (by tossing a coin) ratio in two groups. The total sample size is 362. Group 1 subjects will receive 200 mg of remdesivir administered intravenously on Day 1, followed by a 100 mg once-daily dose of remdesivir while hospitalized for up to 5 days and 4 mg of baricitinib administered as 2 tablets taken orally daily while hospitalized for up to 14 days. Group 2 will receive the same dose of remdesivir plus 6 mg of dexamethasone administered as an intravenous injection daily while hospitalized for up to 10 days. Subjects will be assessed daily while hospitalized. Discharged subjects will be evaluated on days 15, 22 and 29 (in person; if not possible, over the telephone). Assessment will be done clinically using an 8-point Ordinal Scale and National Early Warning Score.

Start date: June 2022
Phase: N/A
Study type: Interventional

The main objective of this study is to offer and evaluate an interim triage approach for patients waiting for surveillance colonoscopies. This will reduce the waiting period and the psychological stressors for our patients and from a scientific point of view allow us to compare the yield of findings for each approach.

NCT ID: NCT04958161 Withdrawn - Covid19 Clinical Trials

Reconditioning Exercise for COVID-19 Patients Experiencing Residual sYmptoms

RECOVERY
Start date: January 2022
Phase: N/A
Study type: Interventional

Individuals who had COVID-19 and are thought to have recovered from the disease often experience long-term symptoms such as fatigue, extreme tiredness and shortness of breath, a condition referred to as Long COVID. Previous studies have shown that regular exercise is beneficial for individuals suffering similar symptoms as a result of other diseases such as Chronic Fatigue Syndrome. The goal of this study is determine if participation in a three-month structured exercise program will improve physical function in individuals suffering from Long COVID.

NCT ID: NCT04953052 Withdrawn - Covid19 Clinical Trials

A Randomized Study to Investigate the Effect of Intravenous Imatinib on the Amount of Oxygen in the Lungs and Blood of Adults With COVID-19 Needing Mechanical Ventilation and Supportive Care.

IMPRESS COVID
Start date: October 14, 2021
Phase: Phase 2
Study type: Interventional

The COVID-19 pandemic has led to an increase in the number of patients admitted to intensive care units (ICU) with acute respiratory distress syndrome (ARDS). ARDS is a severe, life-threatening medical condition characterised by inflammation and fluid in the lungs. There is no proven therapy to reduce fluid leak, also known as pulmonary oedema, in ARDS. However, recent studies have discovered that imatinib prevents fluid leak in the lungs in inflammatory conditions, while leaving the immune response intact. Adding imatinib into the standard care package may, therefore, decrease mortality and reduce the duration of mechanical ventilation compared with standard care alone, in critically-ill patients with COVID-19. To help determine the impact of imatinib in these patients we present a randomised, double-blind, multi-centre, 2-arm, parallel-group, placebo-controlled clinical study of intravenous imatinib in 84 mechanically-ventilated, adult subjects with COVID-19-related ARDS. Study participants (patients who have consented into the study) will receive the study drug (imatinib or placebo) twice daily for a period of 10 days. The effect of the intervention will be tested by measuring the change from baseline in the Oxygen Saturation Index (OSI) at day 10. OSI is a non-invasive means of measuring oxygenation and is an independent predictor of mortality in patients with ARDS, serving thus as a relevant endpoint from which to assess the efficacy of imatinib. Other measurements will include regular blood tests as part of safety assessments. Time on ventilation and morbidity and mortality will be recorded as secondary outcome measures. Blood tests will also allow the investigation of the pharmacokinetic properties of imatinib, as well as biomarkers of inflammation.

NCT ID: NCT04950751 Withdrawn - COVID-19 Clinical Trials

NCT ID: NCT04946162 Withdrawn - COVID Clinical Trials

The Use of Tadalafil in Confirmed COVID-19 Pneumonia.

Start date: April 20, 2020
Phase: Phase 4
Study type: Interventional

Our goal is to assess the effects of Tadalafil in the setting of confirmed COVID-19 pneumonia. In particular we plan to assess its effects on oxygen saturation, P:F ratio, and mixed central venous oxygen We plan to recruit all hospitalized patients at Santa Barbara Cottage Hospital with a confirmed COVID19 pneumonia (positive PCR + clinical signs/symptoms of lower respiratory disease) who meet the Berlin definition of ARDS and have access to measure a mixed venous oxygen saturation. For the purposes of obtaining mixed central venous oxygen, all participating patients will already have an internal jugular central venous catheter in place for inclusion in this study. Since all patients will be intubated, their Legally Authorized Representative (LAR) will be approached to discuss the study and asked to participate in the study by an ICU physician, either the attending physician or a medical resident. Informed consent will be obtained from the LAR by an ICU attending physician or resident involved in the study prior to participation. Patients who meet the above eligibility criteria will have baseline levels of mixed central venous oxygen, oxygen saturation, P:F ratio, blood pressure and PaO2 recorded. Each patient will then receive Tadalafil 40mg once. The above listed parameters will be monitored again 30 minutes after drug administration and 4 hours after drug administration. No other medication or ventilator changes will be made during this time period outside of emergent changes in the setting of patient deterioration. We will continue to analyze the data in the event of emergent ventilator changes.
