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 determine whether Nivolumab will improve disease-free survival compared with placebo.
The stroke has been described as the third cause of death and main cause of disability in the worldwide population. About 60% of the survivors are able to walk following the rehabilitation process, however deficits on lower limbs functions often persists in most cases, affecting the gait and functional mobility. In this sense, several interventions are applied in the clinical practice to optimize the functional performance. Cryotherapy is one of the most used techniques aiming to reduce spasticity temporarily, allowing the training of functional tasks, such as walking. The aim of the present study is to evaluate the immediate effects of cryotherapy (ice pack) on neuromuscular performance, proprioception, passive resistance of dorsiflexors and plantarflexors muscles, and also on gait performance in chronic post-stroke subjects. Eighteen chronic hemiparetic subjects will participate in this crossover placebo-controlled trial. The order of intervention (cryotherapy or placebo) will be randomized. Fifteen days of washout period will be considered. The cryotherapy/placebo will be applied on the posterior area of the leg for 20 minutes. Initially Fugl Meyer will be applied. All other assessments will be performed before and after intervention: spasticity level, classified according to Modified Ashworth Scale; temporo-spatial and angular parameters for trunk, hip, knee and ankle during gait, using a motion analysis system (Qualysis AB, Gothenburg, Sweden); the proprioception (joint position sense), passive resistance to stretching, isometric and isokinetic torques during contractions of plantarflexors and dorsiflexors of the ankle, evaluated through isokinetic dynamometer. Concomitantly, bilateral activation of soleus, gastrocnemius, tibialis anterior and peroneus will be assessed by electromyography during isokinetic dynamometer assessment and gait. The following electromyographic variables will be analyzed: maximum activation amplitude, muscle onset, coactivation index between agonists and antagonists. For statistical analysis, normality (Shapiro Wilk) and homogeneity (Levene) tests will be applied. If the variables have a distribution considered normal and homogeneous, Two-way ANOVA with repeated measures will be applied. Otherwise, non-parametric statistics (Friedman test) will be applied. A significance level of 0.05 will be considered for all statistical tests.
The aim of this study was to compare the clinical and microbiological outcomes of different dosages of metronidazole (MTZ) and of the duration of the systemic administration of MTZ and amoxicillin as adjunct to scaling and root planing (SRP) in the treatment of generalized chronic periodontitis (GChP).
This study is an open-label, controlled, multicenter, international, Phase III, randomized study of transplantation of NiCord® versus transplantation of one or two unmanipulated, unrelated cord blood units in patients with acute lymphoblastic leukemia or acute myeloid leukemia, myelodysplastic syndrome, chronic myeloid leukemia or lymphoma, all with required disease features rendering them eligible for allogeneic transplantation.
Chronic low back pain is potentially disabling for the elderly, and physical exercises are considered the best treatment for this problem. The Pilates method has been proven effective in the improvement of pain and function in patients with low back pain. However, the evidence about the effectiveness of Pilates method in the treatment of elderly patients with low back pain is scarce. Thus, the aim of this study is to investigate the effectiveness of the Pilates method compared to aerobic exercise in elderly with chronic non-specific low back pain. This randomized controlled trial with two arms and blinded assessor will include 74 patients aged between 65 and 85 years, of both sexes, complaining of chronic non-specific low back pain persisting for more than three months and pain intensity greater than 3 points in the Pain Numerical Rating Scale. The elderly will be randomized into two groups: Pilates Group (n = 37) with exercises based on Pilates method; and Aerobic Group (n = 37) with aerobic exercises, stretching and relaxation. Both groups will hold treatment twice a week with duration of 60 minutes for eight weeks. The primary outcomes will be: pain intensity and general disability assessed eight weeks after randomization. Secondary outcomes will be: pain intensity and general disability evaluated six months after randomization; global impression of improvement, specific disability and dynamic balance, muscle strength of the gluteus maximus, gluteus medius and lateral hip rotators and pressure pain threshold evaluated eight weeks and six months after randomization. We expect that the results of this study contribute to the clinical decision-making with respect to pain reduction and, consequently, improving balance and functionality of elderly with chronic low back pain.
Cellavita HD is a stem-cell therapy for Huntington's Disease. This is a first-in-human, non-randomized, phase I study in which participants with Huntington's Disease will receive three intravenous injections and will be followed for 5 years to evaluate safety and tolearability of product and preliminary evidence of effectiveness.
This study will evaluate the safety and efficacy of the injectable drug cabotegravir (CAB LA), for pre-exposure prophylaxis (PrEP) in HIV-uninfected cisgender men and transgender women who have sex with men (MSM and TGW).
It is a controlled clinical trial randomized, double-blind evaluator. Will be considered eligible patients, individuals of both sexes, aged 40 -60, to submit at least four items of knee osteoarthrosis classification criteria, according to the American College of Rheumatology, pain above four points in the visual analogue scale (VAS), diagnosed with knee osteoarthritis and who sought physical therapy treatment. Patients will be randomized by a number sequence generated by a computer using Microsoft Excel (Microsoft Corporation, Redmond, Washington), in opaque envelopes by researcher who will not attend the study.Patients will be divided into two groups: group with knee patellar hole or group without knee patellar hole. Shortly after the selection of the knee, the patient will have his eyes blind or cover in order to keep it '' blind '' regarding the type of knee brace that it would use. Finally evaluator 1 will cover the knee with a black cloak, making the second evaluator ''blind '' regarding the type of knee brace that will be used. Two investigators will carry out the data collection. The first evaluator will collect information on the clinical characteristics of patients, including evaluation form, numerical pain scale, which measures the intensity of pain, test Time Up and Go (TUG) test that measures the basic mobility of movement and test walking eight meters, whose purpose is to measure the time that the individual takes to walk a distance of eight meters.
The purpose of this study is to evaluate and compare the effects of upper limb training with Induced Constraint Therapy (ICT) or robotic therapy. No placebo therapy is used. Motor function, neurological evaluations and quality of life are assessed for the comparison of the therapies.
