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 aim of this study is to assess the efficacy and safety of ozone therapy (vs. placebo) applied into the epidural space through epiduroscopy in Patients with Failed Back Surgery Syndrome. It´s a Prospective, double blind, randomized study. The investigators will study 30 patients of both sexes between 18 and 70 years with chronic back pain after lumbar spine surgery for more than six months. The patients will receive the ozone gas or placebo (oxygen) in the lumbar epidural space, using a spinal endoscope inserted through the sacral hiatus by local anesthesia or sedation. The patients will be evaluated before the procedure, with 30 days, with 3, 6 and 12 months after intervention. This will be run by a researcher who will have no knowledge of the gas (oxygen or ozone) to be injected into the lumbar epidural space with the aid of an epiduroscopic. Will be applied before and after the procedure, pain scales (VAS, McGill, Neuropathic Pain 4, Neuropathic Pain Symptom Inventory), quality of life scale (WHOQOL), functional scales of pain disability (Roland Morris and Oswestry Disabilities Scales). Only one researcher will keep the data confidential until the end of the study.
The purpose of this study is to determine whether hydration with sodium bicarbonate is superior to hydration with saline to prevent contrast-induced nephropathy.
The aim of this international study is to describe the short- and long-term (i.e. up to 2 years following the index event) antithrombotic management patterns (AMPs) in patients hospitalized for acute coronary syndromes (ST segment elevation myocardial infarction (STEMI), Non-ST-Segment Elevation Acute Coronary Syndrome (NSTE-ACS)), and to document the impact of AMPs in clinical outcomes, economic variables and quality of life in a 'real-life' setting and to compare these between sites, countries and regions.
Obesity is a chronic condition with fat-rich diets playing a major role in its etiology. Pharmacological therapy has been proposed for weight loss and maintenance. This study aims to study the intestinal lipase blockade by partial inhibition of fat absorption after treatment with two commercials formulations of Orlistat.
This is a Phase III randomized multicenter double-blind, placebo controlled trial evaluating the safety and efficacy of paclitaxel plus ramucirumab (IMC-1211B) drug product (DP) compared to paclitaxel plus placebo.
This is a randomized, double-blind, double dummy, multicenter Phase 3 study of oral TR-701 FA 200 mg once daily for 6 days versus oral Zyvox® (linezolid) 600 mg every 12 hours for 10 days for the treatment of ABSSSI in adults. Approximately 75 to 100 sites globally will participate in this study. Patients with an ABSSSI caused by suspected or documented gram positive pathogen(s) at baseline will be randomized 1:1 to study treatment
The aim of this trial is to offer continuation of BIBF 1120 treatment for patients with Idiopathic Pulmonary Fibrosis (IPF) who have completed a prior clinical trial with that drug. The primary objective will be to establish the long term tolerability and safety profile of BIBF 1120 in Idiopathic Pulmonary Fibrosis (IPF). As a secondary objective the effects of long term treatment with BIBF 1120 on survival as well as safety and efficacy parameters will be investigated in an open-label, not randomized, un-controlled design.
This expanded access study will assess the efficacy and safety of intravenous Avastin (5 mg/kg every 2 weeks or 7.5 mg/kg every 3 weeks) in combination with fluoropyrimidine-based chemotherapy as first line treatment of patients with metastatic cancer of the colon or rectum. The anticipated time on study treatment is 3-12 months.
The purpose of the study is to compare the survival of participants who receive chemotherapy and ramucirumab versus chemotherapy alone as second line treatment for NSCLC after prior first line platinum-based chemotherapy.
This is an international, randomized, double-blind, placebo-controlled trial to evaluate the clinical efficacy of palifosfamide-tris administered with doxorubicin in combination, compared with doxorubicin administered with placebo in front-line patients diagnosed with metastatic soft tissue sarcoma (STS).
