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 purpose of the study is to evaluate the efficacy of rilematovir compared to placebo treatment with respect to the clinical outcome on the RSV Recovery Scale (RRS).
Previous studies suggested that most patients with Cardiac Electronic Implantable devices have a perception of describing the lifestyle due to a limitation of daily activities and physical exercise, besides the consequences in the psychological aspects such as anxiety and depression. The MHOL-CEID is a randomized controlled trial that Verifies the effectiveness of the Mobile Health of lifestyle that focuses on aspects of physical functional, psychosocial, and quality of life of patients with Cardiac Electronic Implantable Device.
NSCLC comprises of approximately 84 percent (%) of all lung cancers and is often diagnosed at advanced stage due to poor prognosis. Dostarlimab is an immunoglobulin G (IgG)4 kappa humanized monoclonal antibody (mAb) that binds with high affinity to programmed cell death protein 1 (PD 1), resulting in inhibition of binding to programmed death ligand 1 (PD L1) and programmed death ligand 2 (PD L2). This study aims to compare the efficacy and safety PD-1 inhibitors dostarlimab and pembrolizumab, when administered in combination with chemotherapy (pemetrexed, cisplatin and carboplatin), in participants with non-squamous NSCLC without a known sensitizing epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), or receptor tyrosine kinase-1 (ROS-1) mutation, BRAF V600E mutation, or other genomic aberration for which an approved targeted therapy is available. A total of approximately 240 participants will be enrolled in the study for a period of 5 years.
Acute renal failure (ARF) after transcatheter aortic valve implantation (TAVI) is a frequent complication, with significant clinical consequences. History of chronic kidney disease and the use of a large amount of iodinated contrast for planning and procedure are among the main risk factors for the development of this complication. The present study aims to: (1) define the role of non-contrast imaging modalities in pre-procedure planning; (2) evaluate the feasibility and safety of a new TAVI technique without using iodinated contrast; (3) to determine the incidence of acute renal failure in patients with aortic stenosis and chronic kidney disease undergoing TAVI, using the new technique without contrast. The study will be divided into two stages. In the pilot phase, 25 consecutive patients with chronic kidney disease (stage ≥ 3a) will have the TAVI planning and procedure performed without the use of iodinated contrast, but with all the steps subjected to verification by the standard technique, to ensure the safety of the patient. The occurrence of the combined primary safety outcome composed of adverse clinical events within 30 days (defined by the VARC-2 criteria) in less than 20% of cases will be used to define the continuity of the study. In the second phase, 50 patients with chronic kidney disease stage ≥ 3b will be submitted to TAVI with the "zero contrast" technique. The primary outcome assessed at this stage of the study will be the incidence of AKI within 7 days after TAVI using the new technique in this high-risk population.
The aim of this study is to verify the feasibility of a telerehabilitation approach with dance in people with parkinson's disease.
Periodontitis is an inflammatory disease characterized by a dysbiotic microbiome which can lead to bone destruction and tooth loss. Several studies had been reported the association to periodontal disease with systemic conditions and this relation suggests and axis that links oral and gut microbiome. In order to clarify the impact of periodontal condition on gut microbiome, we aim to evaluate the clinical, immunological parameters and the microbiological condition by sequencing of subgingival biofilm and stool samples both before and after non-surgical periodontal treatment with and without antibiotics as adjunct.
This study is a phase II, randomized, open-label, clinical trial including patients with muscle-invasive transitional cell carcinoma of the bladder candidates for radical cystectomy. The study will include patients ineligible for cisplatin. Patients will be centrally randomized in a 1:1 ratio to receive durvalumab plus olaparib (Arm A) or durvalumab alone (Arm B). The clinical study´s hypothesis is that for patients with muscle-invasive transitional cell carcinoma of the bladder who are not fit for cisplatin-based neoadjuvant chemotherapy, Durvalumab monotherapy will have a similar efficacy to historical chemotherapy controls and Durvalumab in combination with olaparib will be associated with an even improved efficacy results in terms of pathologic complete response (pCR).
The study is designed as a multicenter, randomized, double-blind, placebo controlled study to demonstrate the superiority of iptacopan (LNP023) at a dose of 200 mg b.i.d. compared to placebo on top of maximally tolerated ACEi or ARB on reduction of proteinuria and slowing renal disease progression in primary IgA Nephropathy patients.
The primary objective of the study is to evaluate the efficacy (using the modified Friedreich Ataxia Rating Scale [mFARS]) and safety of vatiquinone in participants with Friedreich ataxia (FA).
The objectives of this study are to evaluate the efficacy and safety of sotatercept (MK-7962) treatment (plus background pulmonary arterial hypertension (PAH) therapy) versus placebo (plus background PAH therapy) at 24 weeks in adults with PAH. The primary hypothesis of the study is that the participants receiving sotatercept will have improved 6-minute walk distance (6MWD) at 24 weeks compared to participants receiving placebo.
