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.
Descriptive analytic survey of 1137 and 518 patients aged 16 years or more before and after anesthesia exposure, respectively to assess the anesthesiologist-patient relationship role on patient postoperative perception of the binominal anesthesia-anesthesiologist. The aim of this study was to assess the anesthesiologist-patient relationship role on patient postoperative perception of the binominal anesthesia-anesthesiologist. Period: may/2007 to may/2008
The primary aim of this study is to quantify eyelid position changes in tested and opposite eyes in ptosis patients submitted to 1, 2 or 4 drops of 10% phenylephrine in one eye. The secondary objective is to correlate the eye dominance, severity and laterality of ptosis with eyelid position changes in these 3 groups.
Purpose: To determine whether implantation of an intraocular lens (IOL) with a modified anterior and posterior aspherical surface (Akreos AO, Bausch & Lomb,Inc) results in reduced ocular aberrations (spherical aberration) and in improved contrast sensitivity after cataract surgery. Study hypothesis: the implantation of an intraocular lens (IOL) with a modified anterior and posterior aspherical surface (Akreos AO, Bausch & Lomb,Inc) results in reduced ocular aberrations (spherical aberration) and improved contrast sensitivity after cataract surgery. Setting: Department of ophthalmology, Hospital das Clínicas, University of São Paulo, São Paulo, Brazil. Overall Study design: This will be an intraindividual randomized double-blinded prospective study. Patients will be randomized to receive an aspheric IOL Akreos AO in one eye (25 eyes; Bausch & Lomb, Inc), and an spheric IOL Akreos Fit (25 eyes; Bausch & Lomb, Inc.) in the fellow eye. Ocular aberrations with a 5.0 mm and 6.0 mm pupil will be measured with a dynamic retinoscopy aberrometer after 1 and 3 months. Uncorrected and best-corrected visual acuity, out-focus performance and contrast sensitivity under mesopic and photopic conditions will be also measured. All patients will be followed for 3 months.
The purpose of the study is to see if sorafenib plus best supportive care (i.e. in addition to the non-cancer treatments patients would normally receive) is an effective treatment for lung cancer compared to best supportive care alone. The safety and tolerability of the two treatment groups will also be compared. The goal of the study is to test the ability of sorafenib to improve survival compared to best supportive care alone.
Patients who have completed the 12 weeks treatment of the PATENT-1 trial (study number 12934) will be asked to participate in this long term extension study with BAY63-2521.
There are no treatments specifically approved after recurrence or progression on a non steroidal aromatase inhibitors (NSAI). In light of the need for new treatment options for postmenopausal women after failure of prior NSAI therapy, the purpose of this Phase III study is to compare efficacy and safety of a treatment with exemestane + everolimus to exemestane + placebo in postmenopausal women with estrogen receptor positive locally advanced or metastatic breast cancer refractory to NSAI.
The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Gadavist when used for taking images of the brain and spine. The results of the MRI with Gadavist Injection will be compared to the results of MR images taken without contrast and with the results of the MR images taken with OptiMARK.
The purpose of the study is to determine if advanced prostate cancer patient s that are treated with radiotherapy (RT) plus ipilimumab live longer that those treated with RT alone
This study is a multicentre, randomized, placebo-controlled, fully blinded, clinical trial of twice daily oral valacyclovir 500mg versus placebo with the goal of delaying the need for initiating HAART among HIV infected individuals who neither use nor require HAART, and who have not used chronic suppressive anti-HSV therapy for at least the 6 months prior to study initiation.
This study objective is to check the non-inferiority of the 2 formulations produced by EMS when compared with the same substances and pharmaceuticals forms of the product Condroflex (Zodiac), by promoting the relief of osteoarthrosis symptoms such as pain, stiffness and functional capacity that will be periodically measured by using the "Visual Analog Scale" of pain (VAS) and the questionnaire of Lequesne.
