There are about 9909 clinical studies being (or have been) conducted in Brazil. 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.
This study is intended to explore the possible protective role of anti-androgens in SARS-CoV-2 infection
This is a single-arm, unicentric, single-stage, phase 2 clinical study of therapeutic metaiodobenzylguanidine (MIBG) for patients with metastatic well-differentiated neuroendocrine tumors and radiological progression or intolerance after standard lines of treatment and with MIBG positive scan.
Multicenter, double blind, randomized clinical trial for high-risk patients over 18 years of age, symptomatic for COVID-19 infection, without any severity criteria
Prospective, interventionist, controlled and randomized study to test the effectiveness of multimodal prehabilitation protocol in patients who will undergo gynecological surgery.
The research aims to evaluate the immediate effect of the muscle energy technique (TEM) on postural control responses in the elderly and young adults. The sample will be selected for convenience, being participants of both sexes, young and old. Evaluation of postural control through the force platform will be performed during the unipodal and semi-tandem balance tests. The main parameters of postural control will be calculated using the pressure center derivative. After the balance tests, the participants will be submitted to TEM and immediately afterwards reassessed on the force platform.
The purpose of this study is to evaluate the role of neoadjuvant immunotherapy and to demonstrate high pathologic complete response (pCR) and near pCR rates in melanoma participants with clinically detectable nodal disease and a high risk of recurrence. Neoadjuvant immunotherapy aims to enhance the systemic T-cell response to tumor antigens while detectable tumor is still present, inducing a stronger and broader tumor-specific immune response. Of the neoadjuvant approaches studied within melanoma, the neoadjuvant combination of nivolumab and ipilimumab has demonstrated high pCR and near pCR rates that may translate to prolonged clinical benefit.
The COVID-19 pandemic has been spreading continuously, and in Brazil, until July 19, 2020, there have been more than 2,000,000 cases with more than 79,000 deaths, with daily increases. The present study proposes to evaluate the efficacy of methylprednisolone and heparin in treatment of patients with COVID-19 pneumonia in a randomized, controlled, 2x2 factorial study.
- General Objective To evaluate the effects of curcumin supplementation on cardiovascular risk markers, inflammation, oxidative stress and functional capacity in participants with coronary artery disease. Specific Objectives Assess, before and after supplementation with turmeric: - The nutritional status of the participants; - Blood pressure; - Atherogenic risk; - The expression of transcription factors (Nrf2 and NF-kB), antioxidant enzymes (NQO1, HO-1, sirtuin 1 (SIRT-1)), NLPR3 receptor, as well as the levels of inflammatory cytokines (IL-6, tumor necrosis factor-alpha (TNF-α), protein C reactive (PCR), IL-1, IL 18) and vascular cell adhesion protein 1 (VCAM-1) and E-selectin adhesion molecules; - Routine biochemical parameters; - Lipid peroxidation and oxidized LDL; - The 6-minute walk test, the recovery heart rate and the chair lift test; - Modifiable risk factors before and after supplementation; - The comparison of all parameters between groups.
The Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV2) has been identified in Wuhan, China, which causes severe pulmonary complications and flu syndrome, which has spread rapidly to all continents. Approximately 25% of hospitalized patients require treatment in intensive care units and 10% require mechanical ventilation. The diagnosis is made by the molecular polymerase chain reaction test. However, diagnostic tests are limited. The clinical care of the patient with COVID-19 is similar to that of patients with severe infectious respiratory complications, consisting of support and oxygen supplementation. Several medications have been tested as remdesivir, a pro-drug nucleoside, which acts by inhibiting viral RNA transcription, although a recently published study has shown no benefit. China recently approved the use of favipiravir, an antiviral used for influenza, as an experimental therapy for COVID-19. Hydroxychloroquine is a drug with great potential treatment, as it can inhibit the pH-dependent steps of replication of various viruses, with a potent effect on SARS-CoV infection and spread. In this way, the present study will evaluate the safety and efficacy of the hydroxychloroquine in patients with symptomatic SARS-Cov2.
The purpose of the study is to compare overall response rate (ORR) between treatment groups in participants with higher-risk Myelodysplastic Syndrome (MDS) or Chronic Myelomonocytic Leukemia (CMML) who are not eligible for Hematopoietic Stem Cell Transplantation (HSCT).
