Active clinical trials for "COVID-19"

This study is a non-randomized observation and comparison of immune response between bacteriologically confirmed TB patients under treatment cohort who received COVID-19 vaccine (n=54) vs healthy individuals (n=54). Each participant will receive single or double doses of one of COVID-19 vaccines (Pfizer-BioNTech COVID-19 vaccine, AstraZeneca vaccine or Janssen Ad26.COV2.S COVID-19 vaccine) in the deltoid muscle of the non-dominant arm. Study Duration approximately 1 year. The main focus of this study is to compare the humoral and cellular immunological responses of the COVID-19 vaccines between bacteriologically confirmed TB patients under treatment vs healthy individuals. This study is funded by the Wellcome Trust. The grant reference number is 220211/A/20/Z.

The immunogenicity and safety of AdCLD-CoV19-1 OMI (5.0x10^10 VP (0.5 mL)/dose/Vial) administered as a booster in healthy adults aged 19 years old and above will be evaluated. Outcome assessment will be performed in comparison with Comirnaty Bivalent.

This study is an adaptive, randomized, double blind, platform trial evaluating promising investigational products (IP) for safety and efficacy as early outpatient treatment and post-exposure prophylaxis for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2).

A Clinical Trial of Recombinant COVID-19 Bivalent (XBB+Prototype) Protein Vaccine (Sf9 Cell) in Booster Vaccination to evaluate safety and immunogenicity in healthy population aged 18 years old and above.

A Phase Ⅲ Clinical Trial of Recombinant COVID-19 Trivalent (XBB+BA.5+Delta) Protein Vaccine (Sf9 Cell) in Booster Vaccination to Evaluate Efficacy, Safety and Immunogenicity

This is a Phase 3, Randomized, Double-Blinded Study to Evaluate the Safety and Immunogenicity of Omicron Subvariant and Bivalent SARS-CoV-2 rS Vaccines in Adolescents Previously Vaccinated with mRNA COVID-19 Vaccines.

This study aims to examine the long-term outcomes in Veterans infected and uninfected with SARS-CoV-2 using electronic health record information and structured surveys.

This is a phase 1b, randomized, double-blind, positive control trial in healthy adults, intended to evaluate the safety and immunogenicity profile of RQ3013 in healthy adults primed with a two-dose inactivated vaccine 6-9 months earlier. The study vaccine is administered IM in the upper arm deltoid as single booster shot on day 0.

This is a randomized, phase Ⅱ, single-blind, randomized, parallel-group controlled clinical trial. The study plans to enroll subjects who have completed homologous primary vaccination with either inactivated or mRNA or Viral Vector COVID-19 vaccines (one or two doses) and have not been infected with COVID-19. All subjects will be evaluated for safety and immunogenicity after a single dose booster immunization with Recombinant COVID-19 variant Vaccine (Sf9 Cell) or inactivated COVID-19 vaccine (Vero cell) or mRNA vaccine or Viral Vector vaccine.

The coronavirus disease 2019 (COVID-19) took a toll in institutionalised older adults, who represent a vulnerable population in European countries. The aim of this study is to identify the predictive factors that worsens lung function in post-COVID nursing home (NH) residents. This is a multicenter case-control study in nursing homes of Osona (Catalonia), where individuals with worsened (cases) and normal (controls) lung function will be studied. The inclusion criteria are: female and male from 65 to 95 years old, preserved cognitive capacity and positive diagnosis of COVID-19 at least 3 months prior. We will assess sociodemographic variables, lung function [spirometry], fatigue [Chalder Fatigue Scale], frailty [Clinical Frailty Scale], and activities of daily living (ADL) [modified Barthel index].
