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 the study is to compare how treatment with Fulvestrant (FASLODEX) or Anastrozole (ARIMIDEX) effects disease progression for women with locally advanced or metastatic breast cancer who have not had prior hormonal treatment.
Seventy patients will be previously treated for moderate-to-severe periodontitis according to their individual needs. Thirty days after completion of periodontal treatment, these patients will be randomized to one of the following groups of periodic preventive maintenance (PPM): G1 - performed only control supragingival; G2 - performed supra and subgingival control (when necessary). The maintenance consultations will be scheduled every 3 months for 24 months. The hypothesis is that the effect of the supragingival control (conducted over 24 months) will be similar to the effect of the supra- and subgingival control combined, above the restoration and progression of periodontitis.
The use of combined oral contraceptives has been associated with increased risk of adverse cardiovascular events. The exact mechanism by which these drugs exert this influence is uncertain. It is possible that changes in autonomic nervous system are involved. The objective of these study was to evaluate the effect of the use of a contraceptive containing 20 mcg of ethinyl estradiol and 3mg of drospirenone in the autonomic nervous system in healthy women. Few studies have been conducted in the field of hormonal contraception and evaluation of the autonomic nervous system work and no prospective, controlled study was published so far. These study will be the first.
The aim of this study is to describe the results of Lateral Pharyngoplasty in the treatment of snore and OSAS.
The purpose of this study is to evaluate the impact of different types of intervention on physical activity level and co-morbidities in women workers aged between 40 and 50 years. Method: A total of 195 sedentary women aged between 40 and 50 years and those who agreed to participate were randomized to one of the following interventions: GI = Control (n = 47), GII = Individual counseling (n = 53), GIII = Counseling group (n = 48); GIV = physical training set (n = 47). Were evaluated: Physical Activity level (steps number evaluated by a pedometer), quality of life (SF-36), body composition (BMI, waist circumference and bioelectrical impedance) and clinical variables (plasma glucose and blood pressure).
Chemoradiation has been the standard treatment for advanced cervical cancer for a decade, but one third of women still die from a failure to control systemic disease. In a recent multicentre phase II trial of 46 women the investigators found that, 68% of women had tumours that responded to weekly induction chemotherapy prior to chemoradiation. The induction chemotherapy had acceptable toxicity and did not compromise the standard chemoradiation treatment. In addition, the overall survival and progression free survival at 3 years was 66% (95% CI 4779). These results, together with acceptable toxicity, provide justification for evaluating induction chemotherapy prior to chemoradiation in a randomised phase III trial. The investigators aim to investigate in a randomised trial whether additional induction chemotherapy given on a weekly schedule immediately before standard chemoradiation leads to an improvement in overall survival. The investigators plan to recruit 770 women with locally advanced cervical cancer who are eligible for standard chemoradiation, they will be randomised to weekly carboplatin and paclitaxel chemotherapy for 6 weeks followed by chemoradiation or to chemoradiation alone. The trial will recruit for 4 years with 5 years of follow up period.
The purpose of this study is to determine the pediatric neoplastic response to chemotherapy proposed and evaluate sensitivity to oxaliplatin through immunohistochemistry ERCC-1 expression analysis.
The purpose of this study is to evaluate the efficacy of cortical stimulation (CS) as an adjunctive treatment for chronic neuropathic pain.
This protocol is an international, multicenter, comparative, open and randomized study designed to compare the safety and efficacy (in terms of response rate) from three induction chemotherapy schemes -Thalidomide/Cyclophosphamide/Dexamethasone versus Thalidomide/Dexamethasone versus Thalidomide/Melphalan/Prednisone. Finally, this study is also designed to compare the safety and efficacy (in terms of duration of response) of two maintenance chemotherapy regimens - Thalidomide/Prednisone versus Thalidomide. Each treatment arm will include 100 patients and assessments and scheduled visits will be conducted in three periods: Pre-treatment, treatment and monitoring. Security will be evaluated by monitoring all adverse events, physical examination, vital signs and biochemical studies. Response to treatment will be evaluated according to the EBMT21 criteria and will be assessed on day 1 of each cycle of induction, at the end of nine cycles of induction therapy and monthly during the first year of maintenance therapy and every 3 months thereafter.
This study aims to evaluate the behavior of the intravitreal use of bone marrow derived stem cells in patients with ischemic retinopathy.
