There are about 1933 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.
Blood loss during a surgical procedure is inevitable, its reduction is a key factor for surgical success. Also, to avoid progress to severe complications like hemodynamic decompensation, cardiac arrest or the need to blood transfusions. According to the Center for Disease Control (CDC), there is a usage of more than 17 million transfused blood products units per year. Blood transfusion is a convenient technique for reposition of blood during major bleed, but it involves several probable complications like anaphylaxis, bloodborne infections and others. Consequently, meticulous hemostasis during surgery is crucial to diminish blood loss. Hemostatic agents play a pivotal role during surgical time. Amongst them topical, energy-based and systemic agents are the vast majority. Tranexamic acid (TXA) is a lysine synthetic derivate that inhibits fibrinolysis by blocking the 5 lysine-binding sites to plasminogen. It has been used in clinical practice since 1962 and become very popular after 2010 when the CRASH-2 study showed a decreased risk of death in trauma patients. Tranexamic acid use is widely extended among diverse surgical fields: orthopedics, cardiac surgery and obstetrics. In plastic surgery it uses is limited mainly to craniofacial surgery as a local agent. The aim of this trial is to show the efficacy of tranexamic acid as hemostatic agent in liposuction and to compare its efficacy among different administration routes.
This randomized trial included physiotherapy students, randomized in two groups, experimental one included simulation for developed competencies related to clinical reasoning in physiotherapy interventions for people with low back pain. The second group developed role-playing. this protocol allows us to compare two strategies with simulation for to promote clinical decisions in physiotherapy practice.
Introduction: The SARS Co-2 contagious rate is high (Ro: 2.0-3.0). The infection is aggressive with high pathogenicity. Global confinement impacts all social and economic fields of human activity. Clinical behavior exceeds the capabilities of public health care. With the initial information on the pandemic, it is estimated that 20% of health personnel in direct contact with patients can acquire the disease, despite preventive self-care. The molecular relationship of COVID-19 with the subject's ACE2 protein encourages the virus to enter the host cell, and initiates replication and the immune response, causing an imbalance generating an immunological storm of cytokines, with serious damage to the host. Objective: It is proposed to supply a combined scheme of two compounds by oropharyngeal spray that captures the virus before entering the target cell and orally administer immunomodulatory compounds that regulate the inflammatory response released by the virus, in order to improve the antiviral response. Methodology: A controlled, parallel design, triple-blind, phase II clinical trial will be conducted with two study groups to compare the active compounds (oropharyngeal spray and emulsion) with placebo. Discussion: With the application of the combined scheme of two compounds, a 75% reduction in infection is expected for workers in direct contact with COVID patients.
Double blind, placebo controlled, randomized clinical trial to evaluate the efficacy of ivermectin in preventing progression of disease in adult patients with early stages of COVID-19
The study will focus on effectiveness and safety of rivaroxaban (Xarelto) when given together with acetylsalicylic acid (combination therapy) to patients suffering from coronary artery disease (a condition that affects the blood vessels supplying the heart) and / or peripheral artery disease (a condition that affects the blood vessels of the lower limbs) in the routine clinical practice. The study will help to collect data for prevention cardiovascular death, myocardial infarction (MI), stroke and major adverse limb events in adult patients. The study will focus on information on when and why physicians are starting to treat patients with combination therapy, treatment duration, reasons to discontinue treatment and previous therapies. The study will also investigate treatment outcomes for patients being treated with a combination therapy by their physicians.
This study evaluates the effect of one new form of introduction language and three new modes of providing consent on interactive voice response (IVR) survey cooperation, response, refusal and contact rates, as compared to control group, in Colombia and Uganda.
This study assesses whether oral supplementation with vitamin D contributes to the reduction of body mass index and lipid profile in adolescents and young adults. The intervention group will receive 1000 IU of vitamin D (DV) and the control group 200 IU of DV.
OSCAR (Otilimab in Severe COVID-19 Related Disease) is a multi-center, double-blind, randomized, placebo-controlled trial to assess the efficacy and safety of otilimab for the treatment of severe pulmonary COVID-19 related disease. The study is being conducted in 2 parts (Part 1 and Part 2). Otilimab is a human monoclonal anti-granulocyte macrophage colony stimulating factor (GM-CSF) antibody that has not previously been tested in participants with severe pulmonary COVID-19 related disease in Part 1. The aim of this study is to evaluate the benefit-risk of a single infusion of otilimab in the treatment of hospitalized participants with severe COVID-19 related pulmonary disease with new onset hypoxia requiring significant oxygen support or requiring early invasive mechanical ventilation (less than or equal to [<=] 48 hours before dosing). Participants will be randomized to receive a single intravenous (IV) infusion of otilimab or placebo, in addition to standard of care.
This was a randomized, double-blind, placebo-controlled, 29-day, multicenter study to assess the efficacy and safety of ruxolitinib + standard-of-care (SoC) therapy, compared with placebo + SoC therapy, in patients aged ≥12 years with COVID-19 disease.
Introduction: The COVID-19 pandemic is characterized by significant morbidity and mortality. Treatments have been administered to patients with COVID-19 in order to control viral infection, among them: Hydroxychloroquine (HCQ), Lopinavir/Ritonavir (Lop/r), Remdesivir, Favipavir, Emtricitabine/ Tenofovir acting over bacterial co-infection Azithromycin (Azithro), or modifying the inflammatory response of the host (Tocilizumab, colchicine, dexamethasone, and by other mechanisms (rosuvastatin). Except for dexamethasone clinical trials offer conflicting evidence regarding the effectiveness and safety of therapies. Objective: Evaluate the effectiveness and safety of pharmacological therapies used to treat adult patients with COVID-19. Methods: Pragmatic randomized controlled trial. Study population: Adults aged 18 years or over with a positive real-time polymerase chain reaction (RT-PCR) or with high suspicion of Severe Acute Respiratory Syndrome CoV-2 (SARS CoV-2) and diagnosis of mild, severe or critical pneumonia, requiring hospital management at six hospitals in Colombia. Exclusion criteria: Pregnancy, known allergy to treatment, cirrhosis or hepatic abnormality (transaminases greater than 5 reference values), glomerular filtration rate lesser than 30 ml/min/1.73m^2, history of lung fibrosis, advanced or metastatic cancer. A sample size was calculated from a sensitivity analysis with three scenarios: scenario 1 a total of 1,163 patients, that is, 291 per treatment arm with alpha of Alpha = 0.05; power 0.8; Prop1 = 0.2 and Prop2 = 0.1 (expected difference of 10%) and 10% of possible losses,scenario 2. With the previous parameters and with a Prop1 = 0.15 and Prop2 = 0.05 for a total of 814 patients (204 per arm of treatment). scenario 3. With Alpha = 0.1, Prop1 = 0.15 and Prop2 = 0.05, the other previous parameters, for a total of 686 patients (172 per treatment). in scenario 1 the study will be carried out in two phases. The first phase will be conducted with 400 participants and aims to identify treatments with higher or minimum potential, discontinue treatments with higher toxicity, and have the opportunity of introducing new treatments with potential efficacy. The second phase will be conducted with 1,163 participants to evaluate the effectiveness of the selected treatments. Four interventions have been defined: I1 Emtricitabine/ teneofovir , I2 Colchicine plus rosuvastatin, I3 Emtricitabine/ teneofovir plus Colchicine plus rosuvastatin and I4 standard treatment. Within each institution, participants will be randomly assigned to one of the treatment arms assigned to that institution. Concealment will be kept through software that maintain the assignment concealed until the random assignment is done . Treatment administration will be open. Variables: Sociodemographic and clinical at recruitment; (comorbidities, need for therapeutic support , grade of invasion at admission). Primary outcomes. Effectiveness: Mortality. Safety: Serious adverse events (AE) assessed by the NCI Community Oncology Research Program (NCORP) Guidance for Collection of Adverse Events Related to COVID-19 Infection. Secondary outcomes: Intensive care unit (ICU) admission, requirement of respiratory support, time to death, number of participants cured, any adverse event related to treatment. Analysis: Descriptive for the presentation of summary measures of the basal conditions by type of variable. Bivariate. Description of the basal conditions (with organic failure at admission, without failure at admission), by type of treatment, by participating institution. Description of crude effectiveness and safety by means of the difference of accumulated incidences, each one with 95% confidence intervals (95% CI) Intention to treat analyisis will be done. Adjusted analysis: The ratio and difference of cumulative incidences of mortality at 7 and 28 days and severe adverse events between treatments will be estimated, adjusting for confounding variables using logistic regression models with mixed effects considering each institution as a level or from equations. generalized estimation (GEE). On the other hand, as part of the pragmatic approach, the surface under cumulative ranking curve (SUCRA) will be calculated based on Bayesian theory to define which drug has the highest probability of being the most useful in the management of infection. Ethical considerations: The study has a risk beyond minimum according to the Resolution 8430/1993 of the Colombian Ministry of Health. Informed consent will be explained and signed if the patient is in condition to do so. This protocol will undergo evaluation by the ethics committee at each of the participating institutions and at the National University of Colombia. The protocol follows the Helsinki Declaration and institutional protocols for clinical investigation.
