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.
A phase III multi-center, randomized, open-label trial to evaluate efficacy and safety of ribociclib with endocrine therapy as adjuvant treatment in patients with HR+/HER2- Early Breast Cancer (EBC)
This is a prospective biomarker study of patients with metastatic castration-resistant prostate cancer (mCRPC) undergoing sequential treatment with docetaxel and enzalutamide. The participants will undergo serial pre- and post-therapy blood collection for biomarker analysis as part of the primary objective of the study. The primary goal of this study is to evaluate the association of the AR-V7 status and androgen receptor (AR) gene alterations with PSA response to docetaxel and enzalutamide.
The objective of this study is to evaluate the effect of cabozantinib compared with placebo on progression free survival (PFS) and objective response rate (ORR) in subjects with Radioiodine-Refractory Differentiated Thyroid Cancer (DTC) who have progressed after prior vascular endothelial growth factor receptor (VEGFR)-Targeted therapy.
A population baseline longitudinal study in a major residual malaria hotspot in Brazil to: 1. identify risk factors for residual malaria infection and disease at individual and household level, 2. identify and quantify population changes in P. vivax and P. falciparum to detect reintroductions and to estimate parasite population complexity at baseline and after interventions and 3. describe changing dynamics of malaria incidence and parasitemia prevalence over time, and to assess potential effects of combinations of interventions on malaria control and elimination using mathematical models. The study will be developed in Mâncio Lima, a residual malaria hotspot in northwestern Brazil. The population of study is approximately 2,000 subjects aged 3 months and up, who correspond to all the residents of 20% of the households of the urban area of Mâncio Lima. Will be made Active (ACD) and Passive Case Detection (PCD) every 6 months, over 5 years. (symptom based surveying; microscopy-based diagnosis). Each visit will include interview, physical examination and collection of 100 μL of blood (finger prick) to malaria diagnosis by smear, RDT and qPCR. If the subject will be positive by smear or RDT (rapid diagnostic test for malaria), despite of presence of symptoms, ≥ 20 mL of venous blood will be draw of them to immunology and parasite genetics study and the immediate treatment per MOH(Ministry of Health) guidelines will be performed. Subjects with smear or RDT negative, will be followed for symptoms over the next 6 months. If it is subsequently found to be smear/RDT-positive by PCD, the treatment will be performed. Clinical and epidemiological characteristics of malaria, genetic characteristics of the population of Plasmodium and changing dynamics of malaria transmission will be analyzed.
Older with Chronic obstructive Pulmonary Disease (COPD) were submitted to chronic whole body vibration training during 03 months, receiving a vitamine D dose for each week or placebo vitamine. This group was compared with healthy older which were submitted to the same intervention.
Verify the influence off vitamin D supplementation and a whole body vibration (WBV) protocol during 03 months in older patients chronic obstructive pulmonary disease
This is a randomized, open-label, controlled, multi-center, global Phase III study to determine the efficacy and safety of combining durvalumab ± tremelimumab with standard of care (SoC) chemotherapy (cisplatin + gemcitabine or carboplatin + gemcitabine doublet) followed by durvalumab monotherapy versus SoC alone as first-line chemotherapy in patients with histologically or cytologically documented, unresectable, locally advanced or metastatic transitional cell carcinoma of the urothelium (including renal pelvis, ureters, urinary bladder, and urethra).
Evaluation of heart rate variability in time and frequency domains, in Chronic Obstructive Pulmonary Disease (COPD) after 03 months of vitamine D supplementation and whole body vibration (WBV) training
The purpose of this study is to evaluate the efficacy of pembrolizumab (MK-3745) in combination with chemotherapy (Cisplatin combined with 5-Fluorouracil [FP regimen] or oxaliplatin combined with capecitabine [CAPOX regimen]) versus placebo in combination with chemotherapy (FP or CAPOX regimens) in the treatment of human epidermal growth factor receptor 2 (HER2) negative advanced gastric or GEJ adenocarcinoma in adult participants. The primary hypotheses of this study are that pembrolizumab plus chemotherapy is superior to placebo plus chemotherapy in terms of overall survival (OS).
Coronally advanced flap plus connective tissue graft (CTG) is the gold standard therapy for root coverage. The bioabsorbable porcine collagen matrix (CM) has been widely used in periodontal and mucogingival surgery as a substitute for CTG and has achieved similar results. The CM has the advantage of no need of a second surgical area and availability overcoming the limitations of donor site in autograft. The aim of this study is to investigate the use of Mucoderm® in root coverage procedures combined with extended coronally positioned flap (ECAF), test group (TG), in comparison to the connective tissue graft associated with the ECAF, control group (CG).
