There are about 1910 clinical studies being (or have been) conducted in Colombia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
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.
This is a phase 2/3, randomized, controlled study to assess the reactogenicity, safety and immunogenicity of adjuvanted recombinant SARS-CoV-2 trimeric S-protein subunit vaccine (SCB-2019), when administered as 2-dose vaccination series in children below 18 years of age.
This study evaluates the effectiveness of a multi-component intervention to reduce the gaps in hypertension care and control at a population level in low-income Communes of Medellin, Colombia, and assess the process and fidelity of the intervention's implementation.
This trial is an interventional, randomized, placebo-controlled, adaptive clinical trial in outpatients with symptomatic microbiologically-confirmed SARS-CoV-2, in stable clinical condition, and increased levels of serum C-reactive protein. The hypothesis of this study is that early administration of prednisone for 7 days in patients with evidence of increased C-reactive protein will decrease the progression of COVID-19, prevent clinical deterioration, and hospital admission. Objectives: Primary Objective: To evaluate if early administration of corticosteroids in non-hospitalized participants with proven SARS-CoV-2 infection with compatible clinical symptoms and increased C-reactive protein can prevent hospital admission or early death
This is a randomized controlled trial to evaluate the efficacy and safety of itolizumab in subjects hospitalized with COVID-19.
Until the first half of April, Colombia has more than 2,800 infected cases and a hundred deaths as a result of COVID-19, with Antioquia being the third department with the highest number of cases. Official records indicate that, in Colombia, the first case was diagnosed on March 6, 2020, corresponding to a patient from Italy. However, in conversations with several infectologists and intensivists from Medellín, it was agreed that clinical cases similar to the clinical presentation that is now recognized as COVID-19 had arisen since the end of 2019 when it was still unknown to everyone. The previous suggests that the virus was already circulating in the country since before March 6, 2020. But at that moment, there were no tools to make a clinical identification, nor to diagnose it from the laboratory's point of view. Considering as real the hypothesis that the infection has been circulating in the country since before the first official diagnosis, the question arises: Why does not the country still has the same healthcare and humanitarian chaos that countries such as Italy and Spain are suffering at this time? To answer this question may be that there are differences in vaccination rates with BCG (Bacille Calmette-Guérin or tuberculosis vaccine), which is significantly higher in Latin America compared to those in Europe. This finding could explain to some extent the situation in the country, since previous studies have shown the influence that this vaccine can have on the immune response against various other pathogens, including viruses. Among the population at risk of infection, health-care workers due to their permanent contact with patients are the population group with the highest risk of contracting SARS-Cov-2 and developing COVID-19 in any of its clinical manifestations, and currently there are no vaccines or proven preventive interventions available to protect them. For this reason, this research study aims to demonstrate whether the centennial vaccine against tuberculosis (BCG), a bacterial disease, can activate the human immune system in a broad way, allowing it to better combat the coronavirus that causes COVID-19 and, perhaps, prevents the complications that lead the patient to the intensive care unit and death. In the future, and if these results are as expected, they may be the basis for undertaking a population vaccination campaign that improves clinical outcomes in the general population.
This is a PILOT STUDY, a Phase III double-blind, randomized, placebo-controlled clinical study in which we assess the clinical effect of the prophylactic administration of hydroxychloroquine vs. placebo to healthcare workers working at our University Hospital (HUN). Participants in each arm (n = 43) will be administered with a unique loading dose of 800 mg of hydroxychloroquine the first day followed by 400 mg/week for 90 days. The population to be studied (uninfected healthcare personnel) will be highly exposed to SARS-CoV-2 infection. An active search should be made for individuals who become infected while participating in the study, hence, once the informed consent form is signed, the molecular test for the diagnosis of SARS-CoV-2 infection by RT-PCR will be carried out every 4 days in order to determine as closely as possible the moment the participant becomes positive. The results of the diagnostic RT-qPCR tests will be confronted with: (i) the results of immune monitoring of at least 30 immunological parameters in leukocytes and in plasma (levels of selected cytokines and chemokines analyzed by automated flow cytometry software and (ii) the daily recording of data for the presence or absence of signs and symptoms associated with SARS-Cov-2 infection. For the recording of immune monitoring 20mL blood samples will be taken at eight-time points throughout the 90 days of the stud.
Immunotherapy based on Adoptive Cellular Transfer (ACT) uses several types of immune cells, including dendritic cells, cytotoxic T lymphocytes, lymphokine-activated killer cells, and NK cells. NK cell-based immunotherapies are an attractive approach for treating diseases because of their characteristic recognition and killing mechanisms; they are involved in the early defense against infectious pathogens and against MHC class-I-negative or -low-expressing targets without the requirement for prior immune sensitization of the host and are able to lyse target through the release of perforin and granzymes and using antibody-dependent cellular cytotoxicity pathways mediated by Fc receptor for IgG (CD16). The aim of this project is to evaluate the safety and immunogenicity of allogeneic NK cells from peripheral blood mononuclear cells (PBMCs) of healthy donors in patients infected with COVID-19 collected by apheresis. This allows us to collect cGMP PBMCs and immunomagnetic remove several types of undesirable cells including B, T and CD33+ cells with enrichment of NK cells that will be expanded in bioreactors with GMP culture media (AIM-V) supplemented with human AB serum and GMP grade IL-2, and IL-15. After quality control verification the final NK cell product will be resuspended in 300 mL saline solution for intravenous infusion. Initially, we will enroll in this study ten COVID-19 infected adult patients with moderate symptoms (NEWS 2 scale score>4). Consent forms will be signed by the patient before the therapy. Patients will be treated with three different infusions of NK cells 48 h apart with 1, 10, and 20 million cells/kg body weight. We will follow the patients for any adverse effect, clinical response and immune effects by flow cytometry including markers for NK cells expressing different markers (CD158b, NKG2A, and IFN-y). We anticipated that the release of IFN-y by exogenous NK cells could attract other immune cell populations to boost the immune response against COVID-19.
Cutaneous Leishmaniasis (CL) is a parasitic disease caused by more than 15 different species of the protozoan parasite Leishmania. The CL usually begins with a papule at the site of the sandfly bite, increasing in size to form a nodule that ulcerates in a period of 1 to 3 months. The exact incidence of CL is not known. An estimated 1.2 million cases/year in approximately 102 countries worldwide suffer from different forms of CL. Among the different parasites that cause CL, L.tropica in the Old World and L.braziliensis in the New World are considered to be the most important due to the difficulty of healing, the public importance and the severity of the disease. Pentavalent antimony remains the first choice drug for the treatment of CL and the evidence to support its use is sometimes based on qualitative, retrospective and uncontrolled observations, with only some controlled clinical studies. Antimonials are widely used despite their toxicity, difficulty in the route of administration, and high cost. Miltefosine (hexadecylphosphocholine), an oral medication that has proven effective for some types of Leishmania, is potentially teratogenic, is contraindicated during pregnancy and requires appropriate counseling for female patients of childbearing age.
Enteral nutrition is considered the best way to feed those who can´t be fed orally. the standard protocol of administration includes continuous infusion for 24 hours; nonetheless this support is constantly suspended which causes a decrease in the nutrition administered vs the one formulated. Therefore this randomized clinical trial attempts to compare de standard administration vs. cyclic infusion during night hours measuring the formulated vs the administered volume of enteral nutrition given to the patient. The control group will be assigned standard 24 hour infusion of enteral nutrition while the experimental group will be assigned cyclic infusion during night hours. The variables include volume formulated, volume given in 24 hours, hours and reasons why the enteral nutrition was suspended, and related complications (abdominal distension, vomiting, and diarrhea).
