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 primary purpose of this study is to evaluate the effect of oral administration of L-arginine in the muscular fatigue of the quadriceps, expressed in terms of the Fatigue Resistance Factor (FRF). The secondary purpose of this study is to evaluate the effect of oral administration of L-arginine in the muscular force the quadriceps.
The objective is to establish the effect of sour taste and cold temperature on the pharyngeal swallowing transit time after ischemic hemisphere stroke.
The ARTEMIS-IPF study was conducted to determine if ambrisentan was effective in delaying disease progression and death in participants with idiopathic pulmonary fibrosis (IPF), to evaluate its safety, and to evaluate its effect on development of pulmonary hypertension, quality of life, and dyspnea (shortness of breath) symptoms in this participant population. Participants were randomized in a 2:1 ratio to receive ambrisentan or placebo, respectively. Participation in the study was to be up to 4 years, depending on how long it would take to enroll participants and observe study events. After randomization, visits to the clinic took place every 3 months, and laboratory procedures were performed every month.
In this multinational Phase III study the efficacy and safety of 10 µM AP 12009 is compared to standard chemotherapy (temozolomide or BCNU or CCNU) in adult patients with confirmed recurrent or refractory anaplastic astrocytoma (WHO grade III) or secondary glioblastoma (WHO grade IV).
The study will investigate the comparative efficacy and safety of two oral inhibitors of Kit and PDGFR: nilotinib 400 mg bid, a novel agent, and imatinib 400 mg bid, an approved agent with an established efficacy.
The purpose of this study was to evaluate the safety and efficacy of ofatumumab added to chlorambucil in patients with untreated Chronic Lymphocytic Leukemia.
The primary objective of the study was to explore whether mefloquine can delay or stop progression of progressive multifocal leukoencephalopathy (PML) as measured by JC virus (human polyomavirus or JCV) deoxyribonucleic acid (DNA) levels in cerebrospinal fluid (CSF). The secondary objective of the study was to explore whether mefloquine can delay or stop progression of PML based on neurological deterioration, magnetic resonance imaging (MRI) measures of brain lesion evolution or the formation of new lesions, and mortality.
To understand the dose-response characteristics of PF-00885706 for efficacy in terms of symptomatic relief when used as add-on treatment to esomeprazole 20mg (standard proton pump inhibitor [PPI] treatment), in subjects with gastro-esophageal reflux (GERD) who have inadequate relief with PPIs.
Obstructive sleep apnea (OSA) is independently associated with important heart remodeling that further contributes to overt heart failure. Recent evidences using echocardiogram suggested that continuous positive airway pressure (CPAP) has beneficial effects mainly on left ventricle parameters. However, the evidences regarding the right ventricle are scanty. In addition, no previous studies evaluated morphological and functional characteristics in OSA by magnetic resonance imaging (MRI) as well as the impact of CPAP.
Corticotherapy accelerates maternal postpartum recovery in women with class I HELLP syndrome. The benefit of faster and better recovery would be observed in fewer complications, less utilization of blood products and shorter hospital stay.
