There are about 10004 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.
The goal of this clinical trial is to examine the effect plant-based diet, with a partial replacement of animal protein by plant protein, in blood sugar levels and other health risks of people with type 2 diabetes and excessive weight. The plant-based diet will be compared to a standard healthy diet according to guidelines for people with diabetes. Participants will follow a plant-based or a standard healthy diet for 24 weeks and will maintain their habitual levels of physical activity.
The aim of this clinical study is to compare the effects of tDCS, physiotherapy, and their association with the intensity and frequency of pain in women with Chronic Migraine. For this purpose, the patients included in the study will be distributed among four groups following a factorial model.
The purpose of this follow-up study is to describe the safety in subsequent pregnancies in participants who were previously administered the RSVPreF3 maternal vaccine or control during any prior RSV MAT study. The study participants enrolled in this follow-up study received RSVPreF3 maternal vaccination (any dose) or controls during the following prior RSV MAT studies: RSV MAT-001 (NCT03674177), RSV MAT-004 (NCT04126213), RSV MAT-010 (NCT05045144), RSV MAT-011 (NCT04138056), RSV MAT-009 (NCT04605159), RSV MAT-012 (NCT04980391) and RSV MAT-039 (NCT05169905). No intervention will be administered in this study. The exposure was the intervention (either RSVPreF3 vaccine or control) received by the study participants in the above-mentioned prior RSV MAT studies.
The purpose of this study is to evaluate the efficacy and safety of rocatinlimab in monotherapy and combination therapy treatment in adolescent subjects.
A cross-over randomized clinical trial carried out at the Intensive Care Unit. Patients who are on mechanical ventilation for more than 24 hours will be included in the study. The following techniques will be applied: aspiration in a closed system with an expiratory pause of 10 seconds associated to hyperinflation maneuver with a mechanical ventilator with the Air Stacking technique and aspiration technique in a closed system of aspiration with an expiratory pause of 10 seconds.
The purpose of this study is to evaluate whether milvexian compared to placebo reduce the risk of recurrent ischemic stroke.
This is a Phase 3, multi-center, randomized withdrawal study to evaluate the efficacy and durability of ampreloxetine in participants with MSA and symptomatic nOH after 20 weeks of treatment. This study includes 4 periods: Screening, open label, randomized withdrawal, and long-term treatment extension (LTE).
A prospective, randomized, placebo-controlled, double-blind study that aims to evaluate the effects of combined vitamin D3 and K2-MK7 supplementation on vascular function, sympathetic tone, metabolic biomarkers and inflammatory factors in a population of overweight or obese adults and deficient or insufficient serum levels of vitamin D.
Introduction: Parkinson's Disease (PD) is characterized as a neurodegenerative disorder associated with the progressive loss of dopamine in the basal ganglia region, resulting in classic motor symptoms such as bradykinesia, rigidity, postural instability and tremor. Such symptoms end up affecting the functionality of the upper limbs (ULM) in this population. In recent years, therapy based on Virtual Reality (VR) has been gaining popularity, but studies in the area are still lacking. Objective: To verify the benefits of immersive and non-immersive virtual reality in the functionality of the upper limbs in individuals with PD, and to identify possible differences between them. Methodology: This is a randomized clinical trial, in which the evaluators will be separate from the experimental groups (single-blind). Subjects with PD will be randomized into two groups: Immersive group (IVR), which will receive treatment with virtual reality games in an immersive environment through Leap Motion Controller (LMC) devices together with image projection on a Head-mounted -display (Oculus Quest) and the non-immersive group (RVnI) in which they will receive treatment with the CML on a flat screen. Both treatments will focus on broad and fine upper limb tasks, in a protocol with 4 activities and duration of 27 minutes, twice a week, for eight weeks. The two groups will be evaluated in three moments: before the intervention, immediately after 8 weeks and 60 days after the end of the interventions. They will be analyzed in terms of ADLs, through the TEMPA test and part II of the unified assessment of PD (MDS-UPDRS II); motor assessment (part III) of the MDS-UPDRS and motor staging of PD (Hoehn & Yahr); manual dexterity through the Box and Block test and through the Nine Hole Peg Test; cognition by Montreal Cognitive Assessment (MoCA); quality of life through the PD questionnaire (PDQ-39); the usability of the system (SUS); and possible side effects (Simulator Sickness Questionnaire). This study is expected to show that treatment with immersive VR has greater positive effects than non-immersive VR on the functionality of the upper limbs of individuals with PD.
This is a Phase III, randomized, open-label, multicenter, global study to compare the efficacy and safety of Datopotamab Deruxtecan (Dato-DXd) in combination with durvalumab and carboplatin compared with pembrolizumab in combination with histology-specific platinum-based chemotherapy as first-line treatment of adults with stage IIIB, IIIC, or IV NSCLC without actionable genomic alterations (including sensitizing EGFR mutations, and ALK and ROS1 rearrangements).
