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 purpose of this research study is to learn if the medication Memantine Hydrochloride (the study medication) can help adolescents and young adults with Down syndrome. Dr. Alberto Costa and his research team want to see if a 16-week treatment with this medication can improve the participant's ability to learn and remember things. In this study, memantine hydrochloride will be used. Thus, the researchers want to learn whether the study drug can help improve memory in young adults with Down syndrome. To test the effect of the study medicine, half of the people in the study will receive the study medicine and half will receive a placebo (an inactive substance). Memantine is an approved medication to treat memory and thinking problems in persons with Alzheimer disease. However, little is known about the effect of this medication in persons with Down syndrome and it has not been approved for use in persons with Down syndrome.
The purpose of Phase 1b of this study is to: - Asses the safety, tolerability and activity of carfilzomib, alone and in combination with induction chemotherapy, in children with relapsed or refractory acute lymphoblastic leukemia (ALL). - Determine the maximum tolerated dose (MTD) and to recommend a phase 2 dose of carfilzomib in combination with induction chemotherapy. The purpose of Phase 2 of this study is to compare the rate of complete remission (CR) of carfilzomib in combination with vincristine, dexamethasone, PEG asparaginase, daunorubicin (VXLD) at the end of induction therapy to an appropriate external control.
RIvaroxaban for Valvular heart diseasE and atRial fibrillation trial (RIVER trial).
The purpose of the study was to assess the use of Multikinase Inhibitors (MKIs) in the treatment of patients with a progressive differentiated thyroid carcinoma (DTC) refractory to radioactive iodine (RAI) who do not have any symptoms.
Systemic sclerosis (SSc) is an autoimmune disease with unknown etiology, which affects especially the gastrointestinal tract, lungs, heart and kidneys. Immunological abnormalities characterized by innate and acquired immune disturbances are associated with the disease development. The present study aims to evaluate the efficacy and safety of probiotics in gastrointestinal symptoms, nutritional status and innate and acquired immune responses, by means of the evaluation of IgA, Treg and Th1, Th2, and Th17 T helper subtypes levels in patients with SSc. In addition the levels of CD4+ T helper Th1, Th2 and Th17 subtypes and Treg levels will be compared to a healthy control group.
This study is a randomized, double-blind, double-dummy, parallel group, multicenter, non-inferiority study. The study will enroll adult and adolescent asthmatic subjects who are currently receiving mid dose inhaled corticosteroids (ICS) plus long-acting beta2-agonist (LABA) (equivalent to fluticasone propionate [FP]/salmeterol 250/50 microgram [mcg]twice daily [BD]), either via a fixed dose combination product or through separate inhalers. The study consists of a LABA washout period of 5 days and a run-in period of 4 weeks, followed by a treatment period of 24 weeks, and a follow up contact period of one week. The total duration of the study is 30 weeks. Approximately 1461 subjects will be randomized to one of the following three treatments (487 per treatment): fluticasone furoate (FF)/vilanterol (VI) 100/25 mcg once daily (OD) in the evening (PM) via ELLIPTA™ inhaler plus placebo BD via ACCUHALER™/DISKUS™; FP/salmeterol 250/50 mcg BD via ACCUHALER/DISKUS inhaler plus placebo OD (PM) via ELLIPTA inhaler; FP 250 mcg BD via ACCUHALER/DISKUS inhaler plus placebo OD (PM) via ELLIPTA inhaler. In addition, all subjects will be supplied with albuterol/salbutamol inhalation aerosol to use as needed to treat acute asthma symptoms. This study will determine if FF/VI 100/25 mcg OD via ELLIPTA inhaler is non-inferior to FP/salmeterol 250/50 mcg BD via ACCUHALER/DISKUS inhaler in adult and adolescent asthmatic subjects already adequately controlled on a twice-daily ICS/LABA.

To evaluate the safety and efficacy of eculizumab in the treatment of refractory generalized myasthenia gravis (gMG) as an extension study for the participants who previously completed Study ECU-MG-301(NCT01997229).
Primary dysmenorrhea is the result of hypercontractility and uterine vascular ischemia is the most common gynecologic complaints in young women. According to the intensity of symptoms may impair daily living, work and leisure activities. Pilates brings the concept of moving the body for the recovery, maintenance and promotion of health through exercises that stimulate circulation, improving physical conditioning, flexibility and proper postural alignment, and promote improvement in the levels of body awareness, coordination and muscle control. In this sense, the objective is to investigate the effects of pilates in the symptomatology of primary dysmenorrhea. This is a study to be developed with students of Physical Therapy from the State University of Piauí-UESPI presenting with primary dysmenorrhea compatible clinical picture. A questionnaire will be used for research. The students with the framework of dysmenorrhea that meet the inclusion criteria will be assessed for anthropometric parameters, pain, flexibility, indirect assessment of contraction of transversus abdominis and quality of life before and after the treatment protocol using the pilates method, often 3 weekly meetings, totaling 20 sessions.
A single blind randomized controlled trial (the MoVe ICU study) will be conducted to evaluate the effects on critical patients on invasive mechanical ventilation of early mobilization with a cycle ergometer.
The platelet-rich fibrin (PRF), belongs to a new generation of plasma concentrate with biomechanical processing simplified and without the need for handling blood biochemistry. Some studies have shown the potential of PRF in release growth factors assisting and accelerating the regeneration of soft tissues, however with contradictory results regarding the hard tissues. The aim of this study will be to evaluate through clinical analyzes, histomorphometric and micro-computed tomographic images, the dimensional changes, the quantity and the quality of the tissues formed socket after extractions that receive membranes of PRF. 15 sockets (test group) will receive a membrane of PRF after extraction and the other 15 (control group) received no biomaterial (spontaneous healing).
