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 aim of this RCT is to evaluate the survival of different glass ionomer cement in minimally invasive restorations, with different handling characteristics: hand-mixed versus encapsulated.
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.
Preclinical models show that a daily antiangiogenic regimen at low-dose may be effective against chemotherapy-resistant tumors. The aim of this study is to evaluate the efficacy of maintenance therapy with continuous oral cyclophosphamide and methotrexate in patients with high grade, operable, non-metastatic osteosarcoma (OST) of the extremities. The primary end point is event-free survival (EFS) from randomization.
The purpose of this study is to find out whether it is better to receive a new drug, MEDI4736, or better to receive no further treatment after surgery (and possibly chemotherapy) for lung cancer.
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.
The objective of this project is to assess the occurrence of early improvement within the first two weeks of antidepressant treatment and to correlate this improvement with favorable therapeutic outcome at the end of the acute and treatment continuation phases (8 and 24 weeks, respectively).
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.
