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.
To evaluate the clinical outcomes of intrastromal corneal ring segment (ICRS) implantation to correct keratoconus on eyes with prior refractive surgery.
This global, multicenter, open-label, randomized, controlled study evaluated the efficacy and safety of atezolizumab (an anti-programmed death−ligand 1 [anti-PD-L1] antibody)compared with docetaxel in participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) after failure with platinum-containing chemotherapy. Participants were randomized 1:1 to receive either docetaxel or atezolizumab. Treatment may continue as long as participants experienced clinical benefit as assessed by the investigator, i.e., in the absence of unacceptable toxicity or symptomatic deterioration attributed to disease progression.
Sixty patients will be randomized into three groups to receive the Kinesio taping, placebo Kinesio taping (medical adhesive tape) and control group. The group Kinesio taping receive the correct application of the method described. The placebo group will receive a medical adhesive tape. The control group will not receive any form of intervention.
To establish efficacy of idalopirdine as adjunctive therapy to acetylcholinesterase inhibitors (AChEIs) for symptomatic treatment of patients with mild-moderate Alzheimer's disease (AD).
To establish efficacy of Idalopirdine as adjunctive therapy to donepezil for symptomatic treatment of patients with mild-to-moderate Alzheimer's disease (AD).
The primary objective of this study is to obtain data regarding the safety of olipudase alfa in patients with acid sphingomyelinase deficiency (ASMD) who are exposed to long term treatment with olipudase alfa. The secondary objectives of this study are to obtain data regarding the efficacy of olipudase alfa and to characterize olipudase alfa pharmacodynamics (PD) and pharmacokinetics (PK) following long-term administration.
Primary Objective: The primary objective of this phase 2/3 study is to evaluate the efficacy of olipudase alfa (recombinant human acid sphingomyelinase) administered intravenously once every 2 weeks for 52 weeks in adult participants with acid sphingomyelinase deficiency (ASMD) by assessing changes in: 1) spleen volume as measured by abdominal magnetic resonance imaging (MRI) (and, for the United States [US] only, in association with participant perception related to spleen volume as measured by splenomegaly-related score [SRS]); and 2) infiltrative lung disease as measured by the pulmonary function test, diffusing capacity of the lung for carbon monoxide (DLCO). Secondary Objectives: - To confirm the safety of olipudase alfa administered intravenously once every 2 weeks for 52 weeks. - To characterize the effect of olipudase alfa on the participant perception related to spleen volume as measured by the SRS after 52 weeks of study drug administration. (For the US, the effect of olipudase alfa on the SRS is part of the primary objective). - To characterize the effect of olipudase alfa after 52 weeks of study drug administration on the following outcome measures assessed sequentially: - The effect of olipudase alfa on liver volume; - The effect of olipudase alfa on platelet count; - The effect of olipudase alfa on fatigue; - The effect of olipudase alfa on pain; - The effect of olipudase alfa on dyspnea.
Abstract Objective: Autonomic dysfunction is an important mechanism that could explain many symptoms observed in fibromyalgia (FM). Exercise is an effective treatment, with benefits potentially mediated through changes in autonomic modulation. Strengthening is one of the less studied exercises in FM, and the acute and chronic effects of strengthening on the autonomic system remain unknown. The objective of this study is to assess the effects of strengthening exercises (STRE) on autonomic modulation, pain perception and the quality of life (QOL) of FM patients. Methods: Sedentary women with FM (ACR 1990) will be randomly selected to STRE or flexibility (FLEX) exercises in a blind controlled trial. The intensity of STRE will be set at 45% of the estimated load of 1 Repetition Maximum (RM) in 12 different exercises. The primary outcomes will be pain measured using the Visual Analog Scale (VAS) and the Heart Rate Variability (HRV) analysis. Other outcomes will be assess: fitness measured by treadmill test, the sit and reach test (Wells and Dillon's Bench), handgrip dynamometry; and quality of life by the Fibromyalgia Impact Questionnaire (FIQ), the Beck and Idate Trait-State Inventory (IDATE), a short-form health survey (SF-36). Statistical analyses and ethical procedures: The visual analog scale (VAS) for pain will be the primary measure used to determine sample size. Statistical significance will be set at 5% and power of 80%. These led to at least 58 participants to be randomized. The main hypothesis is that strengthening exercise is a better treatment than flexibility exercise to improve pain, HRV and quality of life. In all measures tested we will consider the null hypothesis (H0) as being the point of equality between groups tested and H1 the point of difference. Bilateral tests were carried out adopting a 5% level of significance. The normality of the results will be tested using the Shapiro-Wilk test. Student's "t"-test for paired samples will be used to perform intra-group comparisons at different times, when the data were normally distributed, and the nonparametric equivalent of Student's t-test (Wilcoxon test) will be used when the data show an asymmetrical distribution. To compare the data between the STRE and FLEX groups, ANOVA for repeated measures will be used, followed by post-hoc Bonferroni's test.
In the present study the investigators aim to determine the efficacy of an immunomodulating topical medication, compared with a topical lubricant, on the treatment of dry eye disease (DED) due to primary or secondary Sjögren's syndrome (aqueous deficient DED) and evaporative DED.
Breast neoplasm is the second most common type in the world. Radiation therapy is a key component in the treatment of breast cancer. Acute skin reaction is one of the most common side effects of radiation therapy. Several studies were performed for prophylaxis of this adverse event, however, until this moment there is no consensus for clinical practice . Second meta-analysis , the ideal candidate for the radiodermatitis prevention would be an agent capable of repairing damage to DNA or agents that promote cell proliferation . The low power laser promotes tissue repair ( reduces inflammatory phase and induces collagen synthesis ) . Its use in the treatment of adverse events of cancer treatment is well established in two situations : in the prophylaxis and treatment of mucositis and in the treatment of lymphedema . The purpose of this study is to use the low power laser in patients with breast cancer undergoing radiotherapy treatment to evaluate the effects of Laser InGaAIP 660Nm in preventing radiodermatitis.
