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.
This is a two-arm, randomized, double-blind, multicenter, pre-operative study to evaluate the effect of combining letrozole and GDC-0032 (also known as taselisib) versus letrozole and placebo in postmenopausal women with estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2 (HER2) untreated, Stage I-III operable breast cancer. Participants will be randomized into one of the two treatment arms with a 1:1 randomization ratio. Letrozole at 2.5 milligrams (mg) will be dosed once daily plus either Taselisib at 4 mg (two 2-mg tablets) or placebo on a 5 days-on/ 2 days-off schedule for a total of 16 weeks.
Phase III trial evaluating raltegravir as an alternative to efavirenz for antiretroviral treatment of HIV-infected patients with tuberculosis.
The objective of this phase III trial is to establish statistical equivalence in terms of efficacy (best overall response rate [ORR], proportion of patients with complete response [CR] plus partial response [PR]) until 18 weeks of first-line treatment with BI 695502 plus chemotherapy versus Avastin® plus chemotherapy followed by maintenance monotherapy with either BI 695502 or Avastin®.
MORPHEOS is a multicenter, randomized, unblinded study, for patients diagnosed with uncontrolled hypertension and at least one antihypertensive medication. Those patients with significant sleep apnea wil be randomized to CPAP or nasal strips for 6 months.
This is a multicenter, double-blind, randomized study comparing the efficacy, pharmacokinetics (PK)/pharmacodynamics (PD), safety and immunogenicity profile of RTXM83 (rituximab biosimilar) vs reference rituximab (MabThera®), both with CHOP, as first-line treatment of Diffuse-Large-B-Cell-Lymphoma (DLBCL). Rituximab biosimilar and MabThera® were both administered intravenously on Day 1 of each 3-week cycle with CHOP chemotherapy for six cycles. Two additional cycles of treatment were permitted at the Investigator's discretion. Patients were followed up for 9 months after last study dose.
As the resolution of the Brazilian Federal Council of Nursing (COFEN) sizing the framework of nursing professionals is essential to ensure the safety and quality of patient care. To achieve such goals actions are needed to evaluate the variety of tasks and performance specific to each area in nursing profession. The National Agency for Health Surveillance (ANVISA), through Board Resolution (RDC-154) determines that the nurse to patient ratio is 1 to 30 in hemodialysis and 1 to 50 on peritoneal dialysis, however these targets are not based on any evidence, and same apply to other Latin-American countries. Objective: To determine the appropriate nurse: patient ratio for peritoneal dialysis unit. Method: This research will be developed in two phases. The first with an observational design with descriptive and qualitative approach. There will be a focus group with experts in the field, to defined the activities and responsibilities of the peritoneal dialysis nurse, and produce a tool with a list of activities. A time-orientated score will be created. In the second stage a cross-sectional quantitative approach will be used. To apply the instrument from by direct observation of activities performed by nurses during their workday. With the instrument activities will be timed and the overall time of each nursing activity will be determined by multiplying the time spent by the total number of patients. It is expected tat this strategy will increase time on treatment and/or decrease dropout rates, by developing an easy test/ formula application to determine the correct ratio according to the peritoneal dialysis program. This tool will provide better outcomes for patients as well as allow for growth of peritoneal dialysis programs with qualified assistance and patient safety.
Study evaluating the safety and efficacy of a novel biologic in the treatment of systemic lupus erythematosus in male and female adults. Patients who qualify will be randomized to either active BMS-931699 or placebo for initially, up to 24 weeks. Patients who complete the initial 24 weeks of treatment and who are responding to therapy will have the option to continue receiving BMS-931699 as part of a long-term extension (LTE). Disease activity and safety will be assessed over the course of the study through laboratory values, various rating scales accepted in systemic lupus erythematosus studies and patient self reporting.
The main purpose of this study is to evaluate the safety and effectiveness of the study drug known as baricitinib in participants with moderately to severely active rheumatoid arthritis who have had an inadequate response to methotrexate therapy.
Objective: To observe the effects of exercise training on vascular endothelial function in patients undergoing coronary artery bypass graft (CABG) alone in phase III after six months of Cardiac rehabilitation programs (CRP). Methods: the investigators contacted all patients undergoing CABG alone in period of 1 year to participate in a CRP with duration of six months with three weekly sessions of 1 and half hour of the duration. All patients underwent biochemical blood tests, muscle strength testing of one repetition maximum (1-RM test) for upper and lower limbs, 6-minute walk test (6MWT), and evaluation of endothelial function (using flow-mediated vasodilation).
Objectives: To assess the effectiveness of two recall intervals on dental caries incidence (primary outcome) in preschool children with low and moderate caries risk. The level of anxiety, oral health related quality of life (OHRQoL), time and cost (secondary outcomes) according to each interval will also be assessed. Methods: The sample will consist of 224 children between 3-5 years of age, of both genders, with low and moderate caries risk according to the clinical criteria adapted from the Secretary of Health of São Paulo. Children will be randomly allocated into two study groups: Group 1 (G1) - oral clinical examination + orientation for oral health and diet on the recall of 12 months; and Group 2 (G2) - oral clinical examination + orientation for oral health and diet on the recall of 18 months.
