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 study is to determine whether low-dose pentavalent antimony is equally effective when compared to the standard-dose regimen in patients with cutaneous leishmaniasis. The study will be done in a field clinic in the state of Bahia, Brazil.
RATIONALE: Giving low doses of chemotherapy, such as cyclophosphamide, before a donor bone marrow transplant helps stop the growth of abnormal cells. It also stops the patient's immune system from rejecting the donor's bone marrow. The donated bone marrow stem cells may replace the patient's immune system and help destroy any remaining abnormal cells. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and methotrexate before or after transplant may stop this from happening. PURPOSE: This phase I trial is studying the side effects and best dose of cyclophosphamide in treating patients who are undergoing a donor bone marrow transplant for Fanconi's anemia.
Primary objective: To demonstrate the clinical efficacy of otamixaban (dose effect via 5 intravenous [IV] regimens) in patients with moderate-to-high-risk non-ST elevation acute coronary syndromes (ACS) and planned early invasive strategy. Secondary objectives: To evaluate safety and assess pharmacokinetics (PK) and pharmacodynamics (PD).
This study will test the effectiveness of two different tuberculosis (TB) prevention strategies, DOTS or DOTS-A. DOTS is the current prevention strategy for TB. DOTS-A is an enhanced prevention strategy that will screen household members of individuals diagnosed with active TB and will provide enhanced treatment as needed. The study will be conducted in 8 communities located in Rio de Janeiro. Study participants will include 6400 males and females of all ages, including active TB patients and their household contacts. Patients with TB identified for treatment at the Health Clinics of 8 urban communities will be eligible. The communities will be assigned to 1 of the 2 prevention strategies, DOTS or DOTS-A. After 4 years, the information gathered during the study will be used to determine the incidence of TB in these communities to see which prevention strategy was more effective in decreasing TB.
Homocysteine recently gained access to the category of risk factor for the development of atherosclerotic cardiovascular disease in the general population. Chronic renal failure patients, even before being introduced to dialysis therapy have almost universal elevation of serum homocysteine; when on dialysis their mortality is above 50% related to cardiovascular disease that we might now speculate, with a contribution of potentially toxic levels of the aminoacid homocysteine.
This 6 arm study will evaluate the efficacy and safety of different doses of P38 Inhibitor (4) in patients with RA currently having an inadequate clinical response to methotrexate. Patients will be randomized to receive P38 Inhibitor (4) (50,150 or 300 qd po,and 25 or 75 bid po) or placebo, and will remain on the stable dose of methotrexate. The anticipated time on study treatment is <3 months, and the target sample size is 100-500 individuals.
The purpose of this study is to evaluate the safety and efficacy of anecortave acetate depot when administered for the treatment of elevated IOP following treatment with steroids.
The study evaluates the effect of inactivation of the immune system with chemotherapy and immunotherapy and infusion of bone marrow stem cells in early onset type 1 diabetes mellitus. We hypothesize that reprograming the immune system will stop immune aggression to the insulin producing cells allowing their regeneration and thus decreasing or eliminating the need of exogenous insulin.
This is a multinational, randomized (1:1), double-blind, double-dummy, comparative, 2- treatmentgroup study in children (age range: ≥6 months and <72 months [< 6 years of age]) with AOM.Subjects will be randomized to receive either telithromycin (50 mg/mL) oral suspension 25 mg/kgonce daily for 5 days or azithromycin (40 mg/mL) oral suspension (10 mg/kg once on Day 1, followed by 5 mg/kg once daily on Days 2-5, not to exceed 500 mg onDay 1 and 250 mg/day from Days 2 - 5. Matching placebo suspensions for telithromycin and azithromycin will also be dispensed to provide blinding for the different treatment regimens.Assessments and reporting of safety will be carried out at all visits.
The purpose of this trial is to understand if adding saxagliptin to a sulfonylurea is safe and works better than increasing the amount of sulfonylurea a patient takes
