NCT ID: NCT05621967 Withdrawn - COVID-19 Clinical Trials

Phonation Therapy to Improve Symptoms and Lung Physiology in Patients Referred for Pulmonary Rehabilitation

Start date: September 7, 2022
Phase: N/A
Study type: Interventional

To investigate Phonation therapy to improve symptoms and lung physiology in patients referred for pulmonary rehabilitation. The study design will be a randomized controlled trial. The primary outcome is improvement in patient symptoms (Borg dyspnea score). Secondary outcomes are improvement in time of breath hold, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), negative inspiratory force (NIF) and improvement in quality of life. The investigators will be investigating tonation breathing techniques (TBT) exercises and music-driven vocal exercises (MDVE). The study population would be patients who are referred to pulmonary rehabilitation (PR) for symptomatic chronic lung disease. The calculated sample size for the study would be 16 patients and the duration of the study would be 8 weeks. The study would be performed after the participant's pulmonary rehabilitation session.

NCT ID: NCT05614245 Withdrawn - COVID-19 Clinical Trials

Safety, Tolerability, and Immunogenicity of Trivalent Coronavirus Vaccine Candidate VBI-2901e With E6020 Adjuvant

Start date: March 2023
Phase: Phase 1
Study type: Interventional

VBI-2901e is an investigational vaccine candidate that uses enveloped virus-like particles (eVLPs) to express the spike proteins of three coronaviruses: SARS-CoV-2 (the virus that causes COVID-19 disease), SARS-CoV-1 and MERS-CoV. The trivalent vaccine candidate is designed to induce neutralizing antibody and cell-mediated immune responses against the spike protein of the original strain of SARS-CoV-2 coronavirus, variants and subvariants of SARS-CoV-2 (such as Beta, Delta and Omicron BA.5) and other related coronaviruses that could emerge in the future. VBI-2901e contains two adjuvants: aluminum phosphate and E6020. The role of the adjuvants is to create a stronger immune response to the vaccine. This Phase 1 study will be an open-label study of VBI-2901e comparing three dose levels of the E6020 adjuvant component (1, 3, or 10 µg per dose) in adults 18 to 40 years of age who had previously received two or more vaccinations with licensed COVID-19 vaccine(s). VBI-2901e at each dose level of E6020 will be administered as either a single dose or two-dose regimen. The purpose of the study is to test the safety of VBI-2901e and to learn more about its ability to boost immune responses against SARS-CoV-2 and the two related coronaviruses SARS-CoV-1 and MERS-CoV.

NCT ID: NCT05609045 Withdrawn - COVID-19 Pandemic Clinical Trials

A Phase 1, Randomised, Double-blinded, Placebo-controlled, Dose-escalation Study to Evaluate the Safety and Immunogenicity of RH109 as Booster

Start date: June 2023
Phase: Phase 1
Study type: Interventional

This is a randomized, double-blinded, placebo-controlled, dose-escalation study to valuate the safety and immunogenicity of RH109 as booster at 2 dose levels for ealthy adults who have received homologous or heterologous vaccination with 3 doses of COVID-19 inactivated and/or mRNA vaccine(s). The purpose of this study is to evaluate the safety and immunogenicity of RH109 as booster for healthy adults who have received homologous or heterologous vaccination with 3 doses of COVID-19 inactivated and/or mRNA vaccine(s).

NCT ID: NCT05602961 Withdrawn - COVID-19 Clinical Trials

A Phase I/II Study of GLB-COV2-043 as a COVID-19 Vaccine Booster

Start date: February 21, 2023
Phase: Phase 1/Phase 2
Study type: Interventional

The scope of this Phase I/II study is to determine whether GLB-COV2-043 is a promising booster vaccine candidate component for adult participants who have received the 2-dose priming course of the mRNA BNT162b2 vaccine against COVID-19, or the 2-dose priming course and a third BNT162b2 injection (i.e., as a "booster"), and, if so, to select the booster dose for further evaluation and potential development.

NCT ID: NCT05589272 Withdrawn - Clinical trials for Post-acute Sequelae SARS-CoV-2 Infection (PASC)

TDCS-potentiated Generalization of Cognitive Training in the Rehabilitation of Long COVID Symptoms

Start date: February 1, 2023
Phase: N/A
Study type: Interventional

The overarching goals of this study are to employ cognitive testing to understand how transcranial direct current stimulation (tDCS), when used concurrently with cognitive training tasks, can affect cognitive impairment symptoms in individuals with long COVID, or post-acute sequelae SARS-CoV-2 infection (PASC), and to examine variability in response between active and sham tDCS treatment groups.

NCT ID: NCT05587881 Withdrawn - Clinical trials for Hematologic Diseases

Clinical Study on the Impact of Covid-19 Vaccine on Allogeneic Hematopoietic Stem Cell Transplantation

Start date: January 1, 2022
Phase:
Study type: Observational

Aim of this study will evaluate the Impact of Covid-19 vaccine on Safety and Efficacy of Hematological Patients Received Allogeneic Hematopoietic Stem Cell Transplantation.

NCT ID: NCT05563168 Withdrawn - COVID-19 Clinical Trials

Study Evaluating Diltiazem in Combination With Standard Treatment in the Management of Patients Hospitalized With COVID-19 Pneumonia

DICOV
Start date: April 2023
Phase: Phase 2
Study type: Interventional

SARS-CoV-2 infection is responsible for hypoxemic pneumonia, which is sometimes serious and associated with excess mortality. To date, with the exception of dexamethasone, which has shown clinical efficacy by reducing the mortality of infected patients, no other therapeutic strategy has demonstrated a curative clinical benefit, particularly in the initial stages facilitating viral eviction. . Based on the mechanism of action and the available data, diltiazem, administered in the first days post-infection, could facilitate viral eradication in these patients through the stimulation of the innate immune response of cells of the infected respiratory epithelium, actor in the fight against SARS-CoV-2. In this context, the investigators propose the DICOV trial, to demonstrate the ability of diltiazem to reduce the viral load more rapidly, in patients hospitalized for COVID-19 hypoxemic pneumonia.

NCT ID: NCT05545683 Withdrawn - COVID-19 Clinical Trials

Safety and Immunogenicity of Inactivated Heterologous Booster Vaccination

Start date: December 1, 2022
Phase: Phase 3
Study type: Interventional

Data from some studies indicate the decline in the effectiveness of the authorized COVID-19 vaccines due to antibody waning following vaccination and the emergence of different variants. These findings support the need to increase vaccination and booster campaigns to protect the adult population against infection. Valneva developed the VLA2001 vaccine, a highly purified, whole virus SARS-CoV-2 vaccine produced on Vero cells and inactivated with β-propiolactone. VLA2001 will be adjuvanted with the licensed adjuvant cytosine phospho-guanine (CpG) 1018 (produced by Dynavax, contained in HEPLISAV-B®) in combination with aluminum hydroxide. On April 14, 2022, VLA2001 was granted Conditional Marketing Authorization (CMA) by the Medicines and Healthcare products Regulatory Agency (MHRA) of the United Kingdom for primary immunization in adults 18 to 50 years of age. This follows the emergency use authorization granted by the Bahraini NHRA in March 2022. As a substantial population has received a primary vaccination series with authorized vaccines, a booster dose to extend the duration and protection may be required.This study aims to investigate the safety, tolerability, and immunogenicity of the VLA2001 vaccine as a booster dose to adults 18 years and older who were primed with another licensed inactivated COVID-19 vaccine at least 6 months prior to enrollment.

NCT ID: NCT05543356 Withdrawn - COVID-19 Clinical Trials

COVID-19 Fourth Dose Study in Australia

Start date: May 2, 2022
Phase: Phase 3
Study type: Interventional

This clinical trial will be a blinded, randomised study to determine the safety, reactogenicity, and immunogenicity of a second booster dose of SARS-CoV-2 vaccines in adults enrolled over two consecutive stages. Stage 1 will commence at the time of study approval and transition to stage 2 once bivalent vaccines are approved and available in Australia.
