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.
Blood flow restriction (RFS) is a widely studied technique that combines low-intensity exercise with vascular occlusion, resulting in muscular benefits. However, its application is challenging due to methodological variations and equipment costs. Tissue Flossing (TF) appears as an affordable alternative, but lacks solid scientific evidence.
This study aims to identify HER2-positive early-stage breast cancer patients who could benefit from neoadjuvant treatment using PHESGO™ (pertuzumab and trastuzumab) without chemotherapy. The approach involves utilizing specific biomarkers (HR and HER2 IHC status) to select participants whose tumors strongly rely on the HER2 pathway, potentially benefiting from a HER2-targeted approach without chemotherapy concurrently.
This study seeks to develop and pilot test a theory-based, integrated technology and counseling intervention to improve ART adherence among sexual and gender minority (SGM) young people living with HIV (ages 18-24) in Rio de Janeiro, Brazil. The intervention aims to improve social support, self-efficacy for taking ART, and teach skills for problem-solving barriers to promote better adherence.
Background: Throughout the history of spinal deformity there have been continuous advances in the surgical treatment. Although many techniques have been successfully developed despite the anatomy complex, screw placement still remains difficult with a significant risk of misplaced implants. The O-ARM guided Navigation is a scanner that allows imaging of screws intraoperatively and could be a tool to facilitate screw revision and reduce the occurrence of misplaced implants. Methods: This is a prospective and randomized clinical study that will be carried out at the University Hospital of the Federal University of Piaui, which provides exclusive assistance to patients of the Unified Health System (UHS), in northeastern Brazil.
This study aims to evaluate the efficacy and safety of subcutaneous (SC) anifrolumab versus placebo in adult participants with cutaneous lupus erythematosus (CLE).
Phase 2/3 randomized and controlled clinical trial, which will evaluate the effectiveness of the association meglumine antimoniate (Glucantime) with tofacitinib in the cure of CL and the capacity of this association to reduce the time of cure of the disease.
The central objective of this study is to characterize the demographic of an ES-SCLC Brazilian cohort treated with durvalumab. Secondarily, to assess the outcomes of durvalumab-based regimens in 1L treatment of ES-SCLC Brazilian patients from the private health care setting.
The goal of this clinical trial is to evaluate the effect of spironolactone in the primary prevention of cardiotoxicity in cancer patients who are undergoing chemotherapy with anthracycline within 12 months. The main question it aims to answer is: • Does spironolactone reduce the incidence of cardiotoxicity in patients undergoing anthracycline chemotherapy? Participants will: - Be cancer patients over 18 years starting treatment with anthracycline; - Be randomized to receive either spironolactone or a placebo for 1 year; - Undergo assessments of their left ventricular ejection fraction (LVEF), global longitudinal strain, and cardiac biomarkers over the 12-month period. Researchers will compare the spironolactone group to the placebo group to see if cardiotoxicity incidence differs between the two.
This is a phase I/II, randomized, double-blind, placebo-controlled clinical trial that will evaluate the safety and potential efficacy of therapy with extracellular vesicles (EVs) obtained from mesenchymal stromal cells (MSCs), patients with moderate to severe acute respiratory distress syndrome due to COVID-19 or other etiology. Participants will be allocated to receive EVs obtained from MSCs or placebo (equal volume of Plasma-Lyte A). Blinding will cover the participants, the multidisciplinary intensive care team and the investigators.
The objective of this study will be to identify the short-term impact of positive, neutral, or negative speech on pain intensity (primary outcome). The secondary outcomes assessed will be the global perceived effect of improvement, patient's expectations regarding spinal manipulative therapy (SMT) intervention, and perception of empathy in the therapeutic encounter in patients with chronic low back pain (CLBP). This study will enroll 60 participants with CLBP aged between 18 and 60 years. This is an exploratory randomized clinical trial. The three groups will receive a manual therapy session after watching the video proposed for their group. First participants will be assessed for pain intensity, low back pain disability, psychosocial aspects, and expectations related to treatment. Secondly, a researcher not involved in the recruitment of patients will randomly allocate the participants into three different groups (G1- group submitted to positive expectation, G2- group submitted to neutral expectation, and G3- group submitted to negative expectation). After the allocation, the participants will watch a short video (no more than 3 minutes) delivering positive, negative, or neutral messages regarding SMT. And finally, a physiotherapist will administer one session of SMT and participants will be re-assessed to investigate the immediate effect of the videos on the pain intensity, global perceived effect of improvement, and expectations. Ultimately, patients will be submitted to a semi-structured interview in which their perceptions about the videos will be investigated. Outcomes will be assessed just immediately after one SMT session.
