NCT ID: NCT04962893 Completed - Covid19 Clinical Trials

Study of a Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) Virus-like Particle (VLP) Vaccine

COVID-19
Start date: June 26, 2021
Phase: Phase 2
Study type: Interventional

This is a randomized, parallel dose assigned, double blind, multi center, Phase II study assessing the efficacy, safety, and immunogenicity of VLP vaccine (Authentic and Alpha variants) in adults between 18 and 59 years who are healthy or have medically stable chronic diseases and who have no known history of SARS-CoV-2 infection

NCT ID: NCT04962347 Completed - Covid19 Clinical Trials

Real World Study of COVID-19 in a Flyover Region

Start date: October 14, 2021
Phase:
Study type: Observational

Real world data are needed on remdesivir (RDV) efficacy in COVID-19, especially in the underserved populations of the United States (U.S.) Gulf Coast as initial clinical trials may not be representative of this population. Specifically, regions such as New Orleans are 60% African American, a much greater proportion of African Americans than initial RDV studies. The main hypothesis is that a real world data based study will provide specific information related to RDV efficacy in COVID-19 patients from underserved / underrepresented populations of the U.S. Gulf Coast. The main goal of this study is to provide population-centered information related on RDV related to indication (stage of disease), dosing, monitoring, efficacy and contraindications for future COVID-19 patients in this underserved region.

NCT ID: NCT04962308 Recruiting - COVID-19 Clinical Trials

Phase: Phase 4
Study type: Interventional

This study is an open-label phase Ⅳ clinical trial of the inactivated SARS-CoV-2 vaccine(CoronaVac)manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to evaluate the immunogenicity and safety of the Inactivated SARS-CoV-2 Vaccine (Vero Cell) in Healthy Population Aged From 18 to 59 Years.

Evaluation of the Safety and Immunogenicity of Influenza and COVID-19 Combination Vaccine

Start date: September 8, 2021
Phase: Phase 1/Phase 2
Study type: Interventional

This is a randomized, observer-blinded, Phase 1/2 study evaluating the safety and immunogenicity of a quadrivalent HA nanoparticle influenza and SARS-CoV-2 rS nanoparticle combination vaccine with Matrix-M1 adjuvant; this combination is referred to as ICC vaccine.

NCT ID: NCT04961476 Completed - Covid19 Clinical Trials

Use of 1-MNA to Improve Exercise Tolerance and Fatigue in Patients After COVID-19

Start date: January 8, 2021
Phase:
Study type: Observational [Patient Registry]

Coronavirus disease 2019 (COVID-19) is a serious respiratory disease that results from infection with a newly discovered coronavirus (SARS-COV-2). Unfortunately, COVID-19 is not only a short-term infection but that patients (pts) recovering from SARS-COV2 infection complain of persisting symptoms including: fatigue, diffuse myalgia and weakness, which may lead to chronic fatigue syndrome. There is currently no evidence that nutritional supplements and/or physical exercise can assist in the recovery of pts with chronic fatigue syndrome. 1-Methylnicotinamide (1-MNA) is an endogenic substance that is produced in the liver when nicotinic acid is metabolized. 1-MNA demonstrates anti-inflammatory and anti-thrombotic properties. Therefore, we investigated whether 1-MNA supplements could improve exercise tolerance and decrease fatigue among patients recovering from SARS-COV-2.

NCT ID: NCT04961385 Completed - Covid19 Clinical Trials

Immunogenicity of the ChAdox1 n CoV-19 Vaccine With 12-dose Vial

Start date: April 1, 2021
Phase:
Study type: Observational

ChAd0x1 nCoV-19 (AZD 1222) is the main vaccine that is planned to roll-out in Thailand and involve vaccinating people especially in high-risk categories. This vaccine is contained in the multiple-dose vial for vaccinating 10 recipients for 0.5 mL each. However, the additional volume of vaccine was overfilled to 6.5 mL per vial which the vaccination can be administered to more than 10 doses. The University Hospital Network (UHOSNET) and Faculty of Medicine Vajira Hospital, Navamindradhiraj University have jointly stipulated the preparation and vaccination of ChAdox1 - n CoV-19 vaccine with 12 doses per vial injection with traditional 21 or 24 G needle. Taken together, The investigators planned to investigate the immune response of participants after first dose of ChAd0x1 nCoV-19 vaccination with such technique

NCT ID: NCT04961333 Recruiting - Long COVID-19 Clinical Trials

Internet-based Multidisciplinary Rehabilitation for Longterm COVID-19 Syndrome

COVID-19
Start date: April 23, 2021
Phase: N/A
Study type: Interventional

Internet-based multidisciplinary interventions will be offered to participants suffering from longterm COVID-19 syndrome. Data will be collected by internet platform at Karolinska Institutet (BASS) before, after rehabilitation and at follow-up after 6 months. Both self-scored questionnaires and physical tests performed at home will be collected to understand the symptomatology, functioning and activity level. Rehabilitation during 8 weeks period will be given in groups as face-to-group, pre-recorded film sessions and by individual approach, the participants will use ExorLive app for physical activity.

NCT ID: NCT04961255 Recruiting - Clinical trials for Healthy Participants

Effects of Post-COVID-19 on Quadriceps Femoral Muscle-tendon Unit

Start date: August 24, 2021
Phase:
Study type: Observational

The physiological/biomechanical characteristics related to muscle and tendon architecture and their possible relationship with the loss of muscle strength and fatigue in patients who were infected with COVID-19 are totally unknown. The aim of this study is to evaluate inflammatory markers, the isometric maximum voluntary force of the knee extensor torque, muscle fatigue, neuromuscular adaptations, muscle architecture, tendinous properties of quadriceps components, oxygen extraction, and body composition in participants after diagnosis with Covid-19 who had moderate and severe levels of involvement compared to a healthy control group.

NCT ID: NCT04961229 Not yet recruiting - Immunosuppression Clinical Trials

Booster Dose of COVID-19 Vaccine for Kidney Transplant Recipients Without Adequate Humoral Response

WHO
Start date: October 2021
Phase: Phase 4
Study type: Interventional

Introduction: Inadequate antibody response to mRNA SARS-CoV-2 vaccination has been described among kidney transplant recipients. Immunosuppression level and specifically, use of antimetabolite in the maintenance immunosuppressive regimen, are associated with inadequate response. In light of the severe consequences of COVID-19 in solid organ transplant recipients, we believe it is justified to examine new vaccination strategies in these patients. Methods and analysis: BECAME is a single center, open label, investigator-initiated randomised controlled, superiority trial, aiming to compare immunosuppression reduction combined with a third BNT162b2 vaccine dose versus third dose alone. The primary outcome will be seropositivity rate against SARS-CoV-2. A sample size of 154 patients was calculated for the seropositivity endpoint assuming 25% seropositivity in the control group and 50% in the intervention group. A sample of participant per arm will be also teste for T-cell response. We also plan to perform a prospective observational study, evaluating seropositivity among ~350 kidney transplant recipients consenting to receive a third vaccine dose, who are not eligible for the randomised controlled trial. Ethics and dissemination: The trial is approved by local ethics committee of Rabin medical center (RMC-0192- 21). Results of this trial will be published; trial data will be available. Protocol amendments will be submitted to the local ethics committee.
