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 present study aims to investigate the effect of transcranial direct current stimulation (tDCS) associated with physiotherapy in parkinson´s rehabilitation. Previous studies showed that tDCS could reduce the bradykinesia, one of the symptom of Parkinson disease. In this way, this study will combine tDCS with physiotherapy in order to enhance the motor rehabilitation and the quality of life.
Primary Objective: To determine the efficacy (as assessed by progression-free survival [PFS]) of vandetanib when compared to placebo in participants with differentiated thyroid cancer that is either locally advanced or metastatic who are refractory or unsuitable for radioiodine therapy. Secondary Objectives: - To determine the efficacy of vandetanib when compared to placebo in this participant population as assessed by efficacy variables including duration of response (DOR), objective response rate (ORR), change in tumour size (TS) and overall survival (OS). - To evaluate the pharmacokinetics (PK) of vandetanib in this participant population and potentially investigate any influence of participant demography and pathophysiology on vandetanib PK. - To demonstrate an improvement in time to worsening of pain (TWP) in participants treated with vandetanib when compared to placebo in this participant population. - To evaluate the safety and tolerability of vandetanib treatment in this participant population.
Objectives: To evaluate if, when considering expectant management in tubal ectopic pregnancy if the complementary use of Methotrexate could provide better results. We evaluate the success of treatment and the time required for titers of β-hCG to become negative. Methods: A double-blind randomized study, held at the Department of Obstetrics UNIFESP. The patients will be divided into two groups: in one patients will be administered a single intramuscular dose of 50 mg/m2 of Methotrexate and in the other patients will be prescribed Placebo intramuscularly. The monitoring will be done by measurement of β-hCG in the 4th and 7th day. When the decline of beta-hCG titers was > 15% in this interval, the patient was followed with weekly dosing of β-hCG until the titers become negative. The criterion of success is when the β-hCG was negative. The treatment failure occurs when surgery was necessary.
Given previous evidence that non invasive brain stimulation enhances the effects of conventional therapies, this randomized sham-controlled trial with 4-weeks follow-up aimed to determine if the repetitive transcranial magnetic stimulation (rTMS)combined with conventional physical therapy (VRT) would be superior to physical therapy in improving upper limb function and quality of life with chronic stroke individuals.
There is evidence that intense physical activity has a potential effect on thrombotic events due to catecholamine release. The hormones leptin and adiponectin have been used as markers of cardiovascular risk, but they are few and contradictory studies that relate physical training intensity and duration of high plasma concentrations of these hormones. The use of antioxidants, such as proanthocyanidins present in grapes, may help in reducing the undesirable effects of intense training.
This randomized, multicenter, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy, safety, and tolerability of lebrikizumab in adolescent participants with asthma whose disease remains uncontrolled despite daily treatment with inhaled corticosteroids (ICS) therapy and at least one second controller medication. Participants will be randomized in a 1:1:1 ratio to receive double-blind treatment with either lebrikizumab ('High' or 'Low') or placebo, administered as subcutaneous (SC) every 4 weeks (Q4W) for 52 weeks, in addition to their standard-of-care therapy. This will be followed by an optional 52-week double-blind active-treatment extension. The anticipated time on study treatment is up to 104 weeks. Participants who complete the study to Week 104, discontinue prematurely or decide not to take part in the optional active-treatment extension will transition to the 20-week safety follow-up period.
This study will evaluate the applications of ganglionar electrical stimulation in patients with Chagas Disease and Ischemic Heart Failure patients.
On a previous study conducted in Brazil. The MMR vaccine from 2 different producers had a mumps seroconversion much lower (71%) than the expected 95%, according to the package insert. This could indicate that a substantial proportion of children was not protected after MMR dose.
A Phase III, randomised, double-blind, placebo-controlled, multi-centre study to assess the efficacy of olaparib maintenance monotherapy in relapsed high grade serous ovarian cancer (HGSOC) patients (including patients with primary peritoneal and / or fallopian tube cancer) or high grade endometrioid cancer with BRCA mutations (documented mutation in BRCA1 or BRCA2 that is predicted to be deleterious or suspected deleterious (known or predicted to be detrimental/lead to loss of function)) who have responded following platinum based chemotherapy.
The objectives of this study were to investigate the effects of massage therapy and occlusal splint therapy in the electromyographic activity and mandibular range of motion (ROM) in individuals with temporomandibular disorder (TMD) and compare the results with those obtained in a group of individuals without this disorder. Twenty-eight volunteers with TMD were randomly distributed into two groups, massage therapy and occlusal splint. Both treatments lasted 4 weeks. Fourteen individuals without TMD were consecutively allocated to the control group. The Fonseca's anamnestic index was used to characterize TMD and allocate the volunteers to either the intervention groups or control group. The electromyographic activity and Mandibular ROM was evaluated before and after treatment using a digital caliper. Two-way analysis of variance with the Bonferroni test was used for inter and intragroup comparisons (level of significance was set to 5%). Cohen's d was used to calculate the effect size.
