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.
There is some controversy in the medical literature regarding the effectiveness of topical lidocaine in children as an adjuvant drug to upper gastrointestinal endoscopy. In children, deep sedation and general anesthesia are often used to sedate children submitting to this procedure. Propofol is an anesthetic drug increasingly popular in this situation, but this drug can only be used with an anesthesiologist in Brazil. Its main side effects include hypotension, respiratory depression and local pain. Lidocaine is frequently used as premedication, and the rationale is that lowering patient discomfort could lower the required dose to achieve the endoscopy and reduce potential side effects. Nevertheless, some patients perceive this medication as uncomfortable. This study aims to compare sedative drug doses between patients who were given either placebo or topical lidocaine.
The purpose of this study is to compare the combination of pemetrexed and carboplatin with the combination of docetaxel and carboplatin in terms of survival without Grade 3 or 4 toxicity in previously untreated patients with locally advanced or metastatic non-small cell lung cancer (NSCLC).
Primary objective was to demonstrate overall survival improvement with aflibercept compared to placebo in patients receiving docetaxel / prednisone for metastatic androgen-independent prostate cancer (MAIPC). The secondary objectives were: - To assess the efficacy of aflibercept compared to placebo on other parameters such prostate-specific antigen (PSA) level, cancer related pain, progression free survival (PFS), tumor-based and skeletal events and health-related quality of life (HRQL); - To assess the overall safety in both treatment arms; - To determine the pharmacokinetics of intravenous (IV) aflibercept in this population; - to determine immunogenicity of IV aflibercept.
Infection with human papillomavirus (HPV) has been clearly established as the central cause of cervical cancer. This Phase IIb study is designed to evaluate the the long-term efficacy, safety and immunogenicity of the 580299 HPV vaccine (CervarixTM) in a Brazilian cohort of women vaccinated in the phase IIb, blinded, primary study 580299/001 (NCT00689741) and having participated in follow-up study 580299/007 (NCT00120848). Only subjects who participated in the primary & follow-up study will be enrolled in this long-term follow-up study. Subjects were aged 15-25 years at the time of entry into the primary study. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
This single arm study will assess the efficacy and safety of Mircera when administered once monthly, subcutaneously or intravenously, for the maintenance of hemoglobin levels in dialysis patients with chronic renal anemia. Patients currently receiving maintenance treatment with epoetin alfa will receive monthly injections of Mircera with a starting dose (120, 200 or 360 micrograms) derived from the dose of epoetin alfa they were receiving in the week preceding study start. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
From the beginning of the AIDS epidemic, pulmonary pneumocystosis (PCP) has been distinguished as one of the most frequent opportunistic diseases with high morbid-mortality. As from 1996, the advent of the highly active antiretroviral therapy (HAART) has changed the characteristics of such epidemic by reducing its related diseases and, as a result, AIDS-related mortality. With the purpose to estimate PCP occurrence and HAART interference, 376 HIV-infected or AIDS patients were studied from January 1992 to December 2002.
The purpose of this study is to assess the ability of eltrombopag to maintain a platelet count sufficient to facilitate initiation of antiviral therapy, to minimise antiviral therapy dose reductions and to avoid permanent discontinuation of antiviral therapy. The clinical benefit of eltrombopag will be measured by the proportion of subjects who are able to achieve a Sustained Virological Response (SVR).
The purpose of the study is to assess if there is benefit when using AZD6244 in the treatment if metastatic colorectal cancer in comparison with another treatment called capecitabine. This study will also assess how safe and well tolerated AZD6244 is.
The general purpose of this trial is to investigate the efficacy and safety of 4 dose strategies of BIBF 1120 treatment for 12 months, compared to placebo in patients with idiopathic pulmonary fibrosis. The primary objective of this study is to demonstrate whether at least one dose strategy is superior to placebo in patients with IPF, in modifying the rate of decline of Forced Vital Capacity (FVC). As a secondary objective, additional parameters will be assessed in order to differentiate between dose strategies on the basis of safety and efficacy
The aim of this study is to evaluate the sustained virologic response (RVS) in HVC patients treated with pegylated-interferon or conventional-interferon and ribavirin, and to investigate the associated factors with RVS, by means of retrospective analysis.
