Active clinical trials for "COVID-19"

The purpose of this study is to assess the safety, tolerability, and immunogenicity of booster dose of vaccine in participants who are generally healthy or with stable pre-existing health conditions. Study details include: The study duration per participant will be approximately 209 days (28 days screening, 1 day vaccination, and 180 days follow-up). The treatment will include 1 booster dose only. The visit frequency will be 6 on-site visits and 1 phone visit.

The aim of the clinical study is to study the safety, reactogenicity and immunogenicity indicators of the EpiVacCorona vaccine, with the involvement of volunteers aged 60 years and above. The research tasks are to: to evaluate the safety of the EpiVacCorona vaccine when administered twice intramuscularly, with the participation of volunteers aged 60 years and older; to evaluate the reactogenicity of the EpiVacCorona vaccine when administered twice intramuscularly, with the participation of volunteers aged 60 years and older; to identify any adverse effects to the administration of the vaccine; to study the humoral and cellular immune responses response following two doses of the EpiVacCorona vaccine, with the participation of volunteers aged 60 and older.

This trial is Stage 2 of a 2-part adaptive trial. The study aims to investigate the safety of 2 doses of a T-cell priming specific cocktail of Coronaviruses peptides mounted on a gold nanoparticle. Note: Stage 1 of the 2-part adaptive trial, testing a specifically selected mix of Dengue virus peptides, commenced Aug 2021. This is now in follow up (NCT04935801).

This is a multicenter, open-label, single cohort study of patients with confirmed COVID-19 syndrome who based on clinical judgment require care in an intensive care unit, regardless of whether or not mechanical ventilation is in use or is anticipated. Patients should be enrolled on the first day of the ICU stay; withdrawal of prior thromboprophylaxis, if any, will follow specific protocol guidance. Enrolled patients will thereafter be administered intravenous frunexian (EP-7041) until disposition from the hospital (including post-ICU non-critical care management)

The objective of this project is to assess the effects of a 2-month cardiopulmonary rehabilitation program on cardiorespiratory fitness in long COVID19 patients. Quality of life, functional capacity, functional respiratory capacity, inflammatory profile, coagulation markers, cognitive functions and brain O2 saturation will also be assessed before and after the exercise rehabilitation program.

An open label, dose escalation, and dose expansion study to evaluate the safety, reactogenicity and immunogenicity of two SARS-CoV-2 DNA plasmid vaccine candidates, VB10.2129 (C1) and VB10.2210 (C2). tThree dose levels will be tested. IM administrations 21 days apart. Part 1 is a dose escalation phase and Part 2 is a dose expansion phase. In Part 2 a selected dose will be tested further in additional healty volunteers.

This is the first-in-human clinical study to see if a single dose of an investigational nasal spray made from a modified plant protein called Q-Griffithsin is safe, tolerated and acceptable for use by healthy adults 18 to 60 years of age.

Age is the main risk factor associated with the severity of COVID-19. From the beginning of the vaccination campaign, elderly subjects are part of the priority population. However, immunosenescence appears to play a role in the natural post-COVID-19 immunity of convalescent elderly subjects and also in the post-vaccination response. However, vaccination recommendations for both naïve (2 doses of vaccine) and convalescent subjects (1 dose of vaccine) do not differ according to age. To date, there is little data to suggest that the response to the vaccine in naïve or convalescent subjects may vary according to age in terms of qualitative and quantitative response and duration.

The purpose of this study is to assess the safety and immunogenicity of MVC-COV1901 vaccine who are generally healthy or with stable pre-existing health conditions and have received 2 doses of Placebo in the main study CT-COV-21

This prospective, multi-center, randomized, observer-blind Phase 2 study. A total of 1320 participants will be divided into 2 groups (660 each) receiving either full dose or half dose of either AZ or PF. Each group is further stratified into 3 subgroups according to three interval duration in term of days after second dose of SV for 60 to less than 90 days, 90 to less than120 days and 120 to 180 days. Each group will be randomized to receive either AZ or PF in 1:1 ratio. Subjects who fulfilled eligibility criteria will be randomly assigned to receive either full dose or half dose of AZ or PF in 1:1 ratio as an IM injection in the deltoid muscle at Visit 1 (V1). Subjects will be follow-up for assessing immunity at day 28 (V3), day 60 (V4) and day 90 (V5) and for safety at day 7 (V2), day 28 (V3), day 60 (V4) and day 90 (V5). At least 50% from each subgroup will be randomly selected to provide additional blood at baseline (V1, day 0) and day 28 (V3) to be used for assessment of T-cell-mediated immunity (CMI)
