Filter by:A parallel, prospective, double-blind, placebo-controlled clinical trial will be conducted in the population affiliated to EPS SURAMERICANA S.A. with positive test for antigen and PCR for SARS-CoV-2. Participants will be randomly assigned in a 1: 1 ratio to the intervention group or the control group using a sequence of random numbers. The patients included will be those with less than 7 days from the onset of symptoms, and without evidence of serious disease. One group will be assigned oral ivermectin therapy at a dose of 600 mcg/kg every 12 hours for 5 consecutive days, and the other group will received placebo. A minimum sample size of 483 patients for each arm was calculated to observe differences. All randomized patients will be included in the analysis according to the randomization arm (intention-to-treat analysis). The primary objective is to evaluate the efficacy of ivermectin in the prevention of severe disease, reduction in the rate of hospitalization, reduction of ICU stay, and mortality. This evaluation will be carried out up to 28 days after the intervention begins. Given the public health emergency, the study is expected to be completed in a period of 6 months from the INVIMA approval.
This study will be a randomized, double-blind, placebo-controlled trial of a third dose of Moderna vaccine versus placebo. Participants will be those that have received two doses of mRNA-1273 COVID vaccine (Moderna) at 0 and 1 months. Participants will be randomized 1:1 to receive either a third dose of the mRNA-1273 vaccine or saline placebo at 3 months post initial vaccination.
This is a prospective intervention study to assess the effectiveness of both the live attenuated and messenger RNA vaccines against SARS-CoV-2 infection
This study was conducted in three African countries on four COVID-19 care centers (CCCs). The CCCs were set up in collaboration with a medical NGO with long experience in recording and monitoring data for cohorts and clinical trials in emergency contexts. The data were recorded using the WHO COVID-19 rapid core case report form.
The purpose of this study is to evaluate the effectiveness of repurposed medications (study drug(s) in reducing symptoms of non-hospitalized participants with mild to moderate COVID-19. Participants will receive either study drug or placebo. They will self-report any new or worsening symptoms or medical events they may experience while taking study drug or placebo. This study is intended to be all remote with no in person visits, unless the study team feels it is in the best interest of a participant to see them in person. Prior and current drug arms are listed on clinicaltrials.gov and will be updated with the activation of any new drug arms. Each study arm will also have its own clinicaltrials.gov entry and will include "Pro00107921" in the Unique Protocol ID. Pro00107921_A - Arm D (Ivermectin 400) - NCT05736861; Pro00107921_B - Arm B (Fluvoxamine) - NCT05890586; Pro00107921_C - Arm C (Fluticasone) - NCT05736874; Pro00107921_D - Arm D (Ivermectin 600) - NCT05894538; Pro00107921_E - Arm E (Fluvoxamine 100) - NCT05894564; Pro00107921_F - Arm F (Montelukast) - NCT05894577; Pro00107921_G - Arm G (Metformin) - NCT06042855.
The study investigates the role of positive pressure, inspired oxygen fraction and different decubiti (seated, supine, prone) on breathing effort (as assessed by esophageal pressure swings) in Covid-19 pneumonia (at different disease stages) and in other causes of respiratory failure. The hypothesis is that positive pressure might be deleterious in terms of breathing effort if the main pathological mechanism associated with Sars-CoV-2 infection in the lung is not alveolar damage (as in other causes of respiratory failure) but vascular impairment as previously reported. The effects of high inspired oxygen fractions and decubiti might also be different with respect to other causes of respiratory failure.
This is an open-label, multicentre study evaluating the effect, safety and tolerability of the two regioisomers 1-(nitrosooxy)propan-2-ol and 2-(nitrosooxy)propan-1-ol (PDNO) infusion given to COVID-19 patients with acute pulmonary hypertension (aPH) and/or acute cor pulmonale (ACP).
Introduction: Coronavirus Disease 2019 (COVID-19) has caused a global pandemic. Epidemiological and clinical inter-individual differences, symptomatology, recovery and humoral response against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) are key factors to better understand and predict the course of the pandemic. As Health Care Workers (HCWs) are caring for infected patients they are more susceptible to infection, which not only is critical for their own health but also because it results in a shortage of HCWs that seriously affects health services. Thus, maintaining the health and welfare of HCWs and enabling their rapid return to work is vital to overcome this crisis. The ProHEpiC-19 cohort presents data on the immune response of HCWs infected with SARS-CoV-2. This dynamic cohort was started in March 2020 and still continues including participants.
This is a prospective, multicentric, non comparative study aiming to evaluate the clinical and virological evolution of high-risk patients infected with SARS-CoV-2 treated withtin the framework of a cohort ATU ('Autorisation temporaire d'utilisation') or authorisation for early access (AAP) delivered by the French drug agency (ANSM).
The proposed study is a phase 1 study which will evaluate the safety, reactogenicity and immunogenicity of two doses regimen of CoVepiT vaccine (OSE-13E) in the population of n=48 healthy volunteers 18 to 45 (inclusive) years old, vaccinated or not by authorized COVID-19 vaccine. Study will be open label and will be randomized 1:1 in two parallel study arms receiving either one single dose or two doses separated by 21 days. First 4 subjects will serve as sentinel cohort and 7 days reactogenicity data of these subjects will be reviewed by the independent safety monitoring committee (SMC) before proceeding to the vaccination of remaining volunteers. The progress of the study will be overviewed by a safety monitoring committee (SMC). The CoVepiT vaccine is a peptide-based vaccine aiming to induce CD8+T-cell-mediated immune response against 11 different proteins of SARS-CoV-2 virus.
