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.
Idiopathic Macular Telangiectasia is characterized by incompetent and dilated retinal capillaries in the foveolar region of unknown cause for retinal telangiectasia. In Idiopathic Macular Telangiectasia, proliferative changes occur in the deep retinal capillary network, leading to intraretinal neovascularization that, unlike in age-related macular degeneration, seems to be retinal rather than choroidal in origin. Before the hemorrhagic and fibrotic state, these vessels may lead to exudation and decrease in the visual acuity. Long-term visual prognosis in patients with this complication may be poor and treatment with laser photocoagulation is unproven. Although newly reported treatment, by photodynamic therapy for neovascular membrane associated with Idiopathic Macular Telangiectasia, may show vision and angiographic stability in a few cases, the improvement may be transient. VEGF has been implicated as the major angiogenic stimulus responsible for neovascularization in AMD, ensuing specific anti-VEGF treatment in these cases. The purpose of the study is to evaluate intravitreal injection of bevacizumab (1.25mg/0.05ml) in the treatment of Idiopathic Macular Telangiectasia.
Evaluation to determine the safety of two laparoscopic procedures to control T2DM.
The objective of this study is to demonstrate that the antibacterial activity of TMC207 is better than placebo when added to a standardized Background Regimen (BR) for treatment of multi-drug resistant TB. Also safety and tolerability will be evaluated.
Evaluation of gemcitabine and cisplatin in combination with either sorafenib or placebo for the treatment of patients with advanced Non-Small Cell Lung Cancer (NSCLC)
The primary purpose of this study is to gather additional safety data for subjects who previously completed the one-year study entitled: "Multicenter Randomized Clinical Trial of the Alair System for the Bronchial Thermoplasty Treatment of Asthma" (Protocol #0602-20, NCT00214526) sponsored by Asthmatx, Inc. Study Subjects who were assigned to the Control Group who elect to participate in this extension study will be followed for an additional two (2) - year period beyond the PREDECESSOR STUDY'S one-year endpoint. Subjects treated with the Alair System who elect to participate in this extension study will be followed for an additional four (4)- year period beyond the PREDECESSOR STUDY'S one-year endpoint. All treatments with the Alair System were completed in the PREDECESSOR STUDY (NCT00214526). The current study is designed solely to collect longer-term follow-up data on the effects of the treatments. The data will be of the same type that was collected in the PREDECESSOR STUDY (NCT00214526), including spirometry, physical examinations, review of symptoms, use of maintenance and rescue medications, and response to Methacholine challenge.
This single arm study will assess the safety and efficacy of a regimen of Avastin plus a taxane, with or without additional chemotherapy, as first-line treatment in patients with locally recurrent or metastatic breast cancer. All patients will receive Avastin (10mg/kg iv every 2 weeks, or 15 mg/kg iv every 3 weeks) plus taxane-based chemotherapy. If taxanes are contraindicated, alternative chemotherapy (other than anthracyclines or pegylated liposomal doxorubicin) may be used. The anticipated time on study treatment is until disease progression, and the target sample size is 500+ individuals.
The main purposes of this study are: demonstrate the safety and efficacy of TPV/r among HCV or hepatitis B virus (HBV) co-infected HIV+population, three-class (NRTI, NNRTI, and PI) experienced, with documented resistance to more than one PI. Determine pharmacokinetic data in this co-infected population and potential utility of using therapeutic drug monitoring (TDM) in improving efficacy outcomes.
To assess the efficacy of celecoxib loading dose of 400mg followed by 200 mg twice a day (BID) versus oral non-selective NSAIDs in acute pain due to ankle sprain.
To evaluate the efficacy and safety of fesoterodine in comparison to tolterodine and placebo for overactive bladder
The purpose of the study is to evaluate intravitreal injection of triamcinolone acetonide after laser panretinal photocoagulation in the treatment of proliferative diabetic retinopathy.
