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 clinical research study to find out if it is safe to stop the drug nilotinib (Tasigna) in chronic myeloid leukemia (CML) patients. Patients who started treatment with imatinib (Gleevec) when they were first diagnosed with CML, then switched to nilotinib (Tasigna) for at least 2 years with the combined time on imatinib (Gleevec) and nilotinib (Tasigna) for at least 3 years and have very small amount of leukemia cells remaining after the nilotinib (Tasigna) treatment will qualify for the study.
Multiple models of replacement tubes for percutaneous endoscopic gastrostomy are available in the market, however durability is variable. In a prospective randomized study, five commercial devices available in the market will be tested in 20 consecutive patients each. Tube performance will be observed during 6 months and durability will be assessed by Kaplan-Meier curves as well as Cox regression analysis.It is hypothesized that tube design and material will influence outcome.
This study is a clinical trial designed to evaluate the effectiveness of a multifactorial falls prevention program in reducing the rate of falls. A multifactorial falls prevention program consisting of an individualized medical management of the modifiable risk factors, a progressive on-site body balance exercise plus a home-based exercise program, an educational/behavioral intervention and a fall prevention booklet will reduce the number of falls and fall rates when compared with usual care.
This is a phase 3, multicenter, randomized, double-blind, placebo controlled study of epirubicin, cisplatin & capecitabine (ECX) with rilotumumab or placebo for untreated advanced MET-positive gastric or gastroesophageal junction (GEJ) adenocarcinoma
This will be a pilot, open label study involving 65 participants. All participants will be followed until seroconversion or until the last enrolled participant completes one year of follow-up, whichever happens first. Participant study number will be given at the screening visit, prior to inclusion in the study. The chosen intervention and study regimen are based on the dynamics of viral infection and the pharmacokinetics of the study drugs. In order to inhibit reverse transcription nucleoside and nucleotide analogues need to be phosphorylated intracellularly. On the other hand, available data indicate that it takes approximately 10 hours between exposure and HIV viral integration, offering a window of opportunity for Raltegravir to block integration and thus prevent infection, given that this drug does not need to be metabolized to exert its effect. The intervention will be maintained for 4 weeks following exposure, in accordance with Brazilian and CDC guidelines for PEP.
Intestinal insufficiency due to short bowel syndrome is a chronic, disabling condition with significant morbidity and mortality.Standard care includes home parenteral/enteral nutrition as well as intestinal transplantation, however multiple drugs, vitamins, antibiotics and symptom-relieving agents may be required. Prescriptional pattern of these drugs will be analyzed in a clinical cohort.
This is a phase II step-wise, randomized, multicenter, double-blind and controlled clinical trial to evaluate the safety and immunogenicity of a attenuated tetravalent lyophilized dengue vaccine manufactured by Butantan Institute. Three Clinical Sites at University of Sao Paulo - Brazil will participate in the study. A total of 300 volunteers will be recruited and divided into two steps: Step A (with no previous exposure to dengue) and Step B (with and without previous exposure to dengue). In step A the participants will be assigned to receive either the lyophilized vaccine, or the liquid vaccine(developed at NIH and produced and formulated at Butantan according to the NIH-Protocol), or the placebo. In Step B participants will be assigned to receive either the lyophilized vaccine, or the placebo. Both vaccine formulations (lyophilized and liquid) are composed of the same attenuated viruses: rDEN1∆30, rDEN2/4∆30(ME), rDEN3∆30/31, and rDEN4∆30. At the end of the study, 20 volunteers will have received the liquid formulation (NIH), 210 the lyophilized formulation (Butantan), and 70 will have received the placebo. All participants included in both steps will be followed by a period of five years after their inclusion in the study. The study hypothesis is that the investigational lyophilized dengue vaccine manufactured by Butantan Institute is safe and confers balanced immune response, after one dose of 1000PFU, to all for vaccine viruses.
Develop and evaluate a model of organization and management in the management of patients with cardiovascular risk factors (hypertension, diabetes mellitus, smoking, obesity, physical inactivity, dyslipidemia and family history) in primary care aimed at the compliance, control and treatment effectiveness.
This is a prospective, randomized, multicenter, parallel, placebo-controlled, phase III study for evaluation of clinical efficacy and immunogenicity of drug Eritromax® - (rHuEPO Blau Farmacêutica S/A.) compared to Eprex® (Janssen-Cilag rHuEPO) for the treatment of patients with secondary anemia to chronic kidney disease (CKD), throughout the correction phase by assessing the change in hemoglobin levels.
The purpose of this study is to evaluate the effects of Passiflora incarnata and Isoflavone combination in relieving the symptoms associated with Climacteric Syndrome.
