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.
This research project is about a physical activity intervention in pediatric outpatients to try control and prevent heart diseases such as hypertension, obesity, high cholesterol.
The radioactive radioiodine therapy (Na131I) for the treatment of differentiated thyroid carcinoma is a procedure used for ablation of remaining thyroid tissue after thyroidectomy and metastases. Although serious complications are uncommon after treatment, there are well-documented adverse reactions secondary to the involvement of the salivary glands, such as dry mouth, pain in the parotid glands and dysphagia, even after administration of low doses of radioiodine. However, ocular complications of such treatment are scarcely reported in literature. Among them the investigators can mention recurrent and chronic conjunctivitis, keratoconjunctivitis sicca and dry eye, affecting 23% of patients undergoing radioactive iodine therapy. Dysfunction of the lacrimal gland is described in recent studies, especially after high cumulative dose of the drug. Likewise, epiphora and nasolacrimal duct obstruction have been reported as complications associated with the use of radioiodine, although studies are not available to assess its true incidence through the systematic evaluation of patients. It can be seen in routine practice that these patients would normally be referred for ophthalmological examination only if a complaint, what happens in the process of OVL already installed after the use of high doses of radioiodine. With the early evaluation of these patients, the investigators focused on detecting the process of ongoing obstruction in order to study interventions that prevent its final installation.
To compare the maintenance of efficacy of the combination of etanercept 50 mg once weekly plus methotrexate with or without other disease modifying antirheumatic drugs therapy with that of methotrexate with or without other disease modifying antirheumatic drugs therapy at Week 52 in subjects with moderately to severely active rheumatoid arthritis who have achieved low disease activity after 24 weeks of therapy with open label etanercept 50 mg once weekly plus MTX with or without other disease modifying antirheumatic drugs therapy.
The purpose of this study is to determine objective response rate (ORR), lasting at least 4 months (ORR4), with brentuximab vedotin in participants with cluster of differentiation antigen 30 positive (CD30+) cutaneous T-cell lymphoma [mycosis fungoides (MF) and primary cutaneous anaplastic large cell lymphoma (pcALCL) ]compared to that achieved with therapy in the control arm.
Evolution of swallowing in patients undergoing lateral pharyngoplasty with preservation stylopharyngeal muscle.
Primary Objective: - To compare the continuation of treatment with docetaxel versus switching to cabazitaxel regarding the time to PSA (Prostatic Specific Antigen) progression (TTP-PSA), in patients with Castration-Resistant Prostate Cancer (CRPC) that, after four cycles of docetaxel, have minor PSA response (defined as a reduction between 1% and 49%) or increase of up to 24% in PSA levels. Secondary Objectives: - PSA response rate - Overall survival (OS) - Incidence of Adverse Events
