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.
Triamcinolone has already been used by different routes of administration to treat diabetic macular edema. In the present study, intravitreal injection (IVI) and posterior sub-Tenon's infusion (STI) of triamcinolone acetonide (TA) during phacoemulsification cataract surgery in eyes with refractory diffuse diabetic macular edema are tested.
Two intraocular irrigating solutions (BSSPlus versus Lactated Ringer's) are compared in this prospective, randomized, masked trial to investigate for differences in preservation of corneal integrity after phacoemulsification cataract surgery.
The purpose of this study is to determine the safety, efficacy, predictability, and stability of laser in situ keratomileusis (LASIK) to correct high anisometropia in patients 8 to 15 years old in whom conventional treatments have failed.
Same patients with dilated myocardiopathies with large areas of fibrosis has not been as successful after Cardiac Resynchronization Therapy, for Heart Failure patients in functional class III or IV. Therefore the investigators have decided to associate the Stem-Cell implant with Cardiac Resynchronization Therapy in these patients.
This 6 arm study will evaluate the efficacy, safety and pharmacokinetics of 5 doses of RO4998452 compared to placebo in patients with type 2 diabetes mellitus. Patients will be randomized to one of 6 groups to receive RO4998452 at doses of 2.5mg, 5mg, 10mg, 20mg or 40mg po daily, or placebo daily. Patients pre-treated with stable metformin will continue to take their usual dose of metformin throughout the study.The anticipated time on study treatment is <=3 months
Many cardiac patients requiring device (defibrillator or pacemaker) related surgery are on chronic oral anticoagulation therapy (usually coumadin). The risk of blood clot formation related to stopping oral anti-coagulant therapy is currently managed by using bridging heparin therapy in patients with moderate to high risk of blood clot formation. There is a substantial risk of bleeding in the pocket where the device is situated (pocket hematoma)related to bridging therapy. The purpose of this study is to compare the current standard of care of bridging with heparin to an experimental strategy of continuing coumadin therapy in higher risk patients undergoing device surgery, with the hypothesis being that the continued oral anti-coagulation group will have a lower pocket hematoma rate as compared to the bridging with heparin group.
This study will test whether darapladib can safely lower the chances of having a cardiovascular event (such as a heart attack or stroke) in people with coronary heart disease.
Compare VBL and cyanoacrylate injection (CI) in the treatment of EV in patients with advanced liver disease regarding eradication, bleeding, mortality, complication and recurrence rates.
The purpose of this study is to evaluate the inflammatory symptoms and signs (hyperemia, edema and pain) reduction after 24 hours of treatment with ketoprofen drops when associated to amoxicillin.
The purpose of this study is to determine if dynamic psychophysical testing along with genetic screening will allow to identify pre-operatively women who will suffer severe acute pain post-operatively and the subset who may experience chronic pain following cesarean section.
