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 this study is to assess the efficacy and safety of intratumoral (IT) ulevostinag PLUS pembrolizumab (MK-3475) compared to pembrolizumab alone as a first line treatment of adults with metastatic or unresectable, recurrent head and neck squamous cell carcinoma (HNSCC). The primary study hypotheses are that IT ulevostinag in combination with pembrolizumab results in a superior Objective Response Rate (ORR), per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1), compared to pembrolizumab alone: 1. In participants with a tumor that has a programmed cell death-ligand 1 (PD-L1) Combined Positive Scoring (CPS) ≥ 1, and 2. In participants with a tumor that has a PD-L1 CPS ≥ 20.
Alzheimer's disease (AD) is characterized by a progressive decline in cognitive functions, interfering with autonomy and independence. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM 5), mnemonic dysfunction in AD must be related to aphasia, apraxia, agnosia, or changes in executive function. The clinical picture of the disease can be described as mild, moderate and severe. In the mild phase, the patient is disoriented and with difficulties in thinking, in later stages memory lapses become more intense and frequent. The symptoms of apraxia, aphasia and agnosia appear, causing a noticeable impact on the performance of simple daily activities, and neuropsychiatric and behavioral symptoms are expressed. Existing pharmacological treatments for AD treatment are able to minimize the symptoms of the disease, but are not able to promote cure. Therefore, studies have sought to better understand non-pharmacological strategies, aiming at optimizing the benefits of using the drug. Studies have suggested that tDCS promotes significant effects on cognitive processes assessed through cognitive tasks, not only in healthy individuals but also in clinical populations. Cognitive training (TCog) has similarly shown excellent results in the treatment of cognitive deficits due to AD. Thus, the present study aims to investigate when (before, during or after) the tDCS should be applied to potentiate the effects of TCog in people with AD by comparing four protocols of application of neurostimulation associated with TCog.
Epilepsy is a chronic disease with a psychosocial impact on the patient. The technique called 'Mandala of Emotions' (ME), derived from the Traditional Chinese Medicine, facilitates expression and awareness of emotions. In our pilot case study, the group "intervention with ME" managed to arouse their emotions and after the intervention felt lighter and relaxed at a higher frequency than the control group. We conducted a blind case control study to further assess usefulness of ME. Materials and Methods: Patients and caregivers recruited at an Epilepsy Outpatients Clinic with the approval of Ethics Committee were randomly divided into groups 'Control' (n=57) and 'Intervention' (n=53). In the ME group, five colored stones (green, red, yellow, white and black) were applied according to the emotion chosen by the participant. Individual assessment performed blinded to who received intervention applied a structured questionnaire and Likert-scales about the degree of relaxation and feelings pre- and post-experiment.
Delirium is a disorder of consciousness characterized by an acute onset and fluctuating course of impaired cognitive functioning. It is associated with unfavorable outcomes in hospitalized patients, including longer hospital length of stay, need for subsequent institutionalization and higher mortality rates. Patients in the intensive care unit (ICU) under mechanical ventilation and older age are at higher risk for the development of delirium. Several studies suggest that minocycline, through its anti-inflammatory effect, was able to prevent neuronal dysfunction in different models of ICU-related diseases. Thus, the present study aimed to evaluate the effect of minocycline on delirium development in critically ill patients. Patients will be randomized into one of two groups: the intervention group that will receive 100mg of minocycline 2 times a day and the placebo group. Medication or placebo will be continued for 28 days or until ICU discharge (whichever occurs first). Delirium will be diagnosed by the CAM-ICU. Coma will be defined by the Richmond Agitation-Sedation Scale (RASS) score of -4 or -5 and biomarkers will be used as alternative outcomes related to the pathophysiology of the disease (IL-1, IL-6, IL-10, and BDNF).
Actinic cheilitis is a potentially malignant lesion on the lower lip, which can progress to more serious illnesses such as cancer if not treated. Usually treatment of this condition is only based on clinical appearance, but there is no established cure treatment. Topical imiquimod is a medicine indicated for the treatment of skin diseases, but it has not yet been proven to treat actinic cheilitis. In this research, the investigator's aim is to evaluate the response to actinic cheilitis treatment with the current standard treatment compared to high and low concentration imiquimod topical formulations.
This study is a group controlled clinical trial. ParallelParallel study, patients aged 25-50 years, with Migraine Chronicle. Twelve sessions will be held during four mindfulness practice with four recordings (one per week). As a brainwave biomarker, the Muse, a Electroencephalogram (EEG). The investigators will use the MIDAS questionnaire, the HIT-6 Questionnaire and the FFMQ-BR. Based on the use of tDCS in patients with chronic pain, and in benefits of Mindfulness practice in these patients, the objective is to evaluate if the mindfulness-associated TCCA provides satisfactory results in the painful prophylaxis of patients with chronic migraine.
Cellavita-HD is a stem-cell therapy for Huntington's Disease. Open label, single treatment, extension study for long-term safety and efficacy evaluation of Cellavita-HD intravenous administration in Huntington's disease patients who participated of ADORE-DH trial.
Combined training is a cornerstone intervention to improve functionality and to reduce blood pressure in older adults with hypertension. Acute blood pressure lowering after exercise seems to predict the extent of blood pressure reduction after chronic training interventions. Based on that, the same weekly amount of exercise performed more frequently could be more beneficial to blood pressure management. The aim of the present study is to evaluate the effects of a combined exercise program performed four versus two times per week on 24-h ambulatory blood pressure and other cardiovascular risk factors in older individuals with hypertension.
