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 trial is to establish bioequivalence of the fixed dose combination (FDC) tablets (containing 12.5 mg empagliflozin/850 mg metformin) (Test, T) compared with the single tablets (10 mg empagliflozin and Glifage® 850 mg tablets) (Reference, R).
The purpose of this study is to compare the efficacy of teclistamab daratumumab (Tec-Dara) with daratumumab subcutaneously (SC) in combination with pomalidomide and dexamethasone (DPd) or daratumumab SC in combination with bortezomib and dexamethasone (DVd).
Objective: This randomized, double-blind, parallel, placebo-controlled clinical trial aims to evaluate the effect of propolis with two distinct concentrations (10% and 15%), and the impact on volunteers' quality of life. Materials and methods: Volunteers meeting the inclusion and exclusion criteria will be randomized and allocated into three groups: Group 1- placebo - toothpaste without active ingredient, Group 2- toothpaste with 10% propolis and Group 3. - toothpaste with 15% propolis. Number of teeth will be used as sample unit, totaling 22 teeth per group. Volunteers will receive oral hygiene instruction with guidance to brush their teeth three times a day with toothpaste corresponding to the groups in which they will be allocated for 30 days. The evaluation of dentin hypersensitivity will be performed with three (3) evaluation times: baseline (immediately before the beginning of treatment), 15 and 30 days, through tactile and evaporative stimuli, using the visual analog scale (VAS). The self-reported evaluation of the volunteers will be done through a questionnaire before the beginning and after one month with the completion of the research to determine the impact of treatment on their quality of life. The data regarding HD in VAS, if present normal distribution, will be used Two-way analysis of variance (ANOVA) with Tukey's post hoc for comparison between treatments. However, if the data show anormal distribution, Friedman to compare the different times in the same group (intra group), and Kruskal Wallis to make the comparison between groups (inter group). To evaluate the QEHD ordinal data, Wilcoxon and Mann-Whitney tests will be used. Bioestat 5.3 (Belém, Pará, Brazil) will be used, considering an alpha level of 5%.
Nuvo Tapered IF (internal hexagonal connection) and CF (conical connextion) Implants were designed for the the oral functional rehabilitation using dental implants, allowing for treatment of patients with different bone qualities. The aim of the study is to confirm the long-term safety and clinical performance of implants and abutments of Nuvo IF and CF in daily dental practice setting, by means of prospective collection of clinical data in randomized clinical trial using these devices. Devices will be used , according to manufacturer indications in the IFU. Patients will be followed for 36 months after implant loading.
Standard therapy for localized rectal cancer includes chemotherapy and radiation therapy, followed by a "recovery" period of 7-12 weeks, surgery and adjuvant chemotherapy for 3-6 months. Even though this protocol achieves high cure rates, many patients need a rectal amputation with placement of definitive colostomies. About 10-20% of patients have a complete clinical response to chemo-radiation and no tumor can be found in the surgical specimen. These patients can be followed with close surveillance and avid surgery. The aim of this study is to evaluate if a strategy including the use of a highly active chemotherapy called "FOLFIRINOX" during the 12 weeks between the end of radiation therapy and evaluation for surgery increases the rates of complete response and, therefore, allows more patients to undergo non-surgical management.
Immunotherapy with anti-PD-1/PD-L1 agents either as single agents or combined with chemotherapy is now considered the standard of care for patients with non-small-cell lung cancer. However, it has not been incorporated in the Brazilian Public Health System because of concerns about patient eligibility, safety and costs. It is known that simple biomarkers can be used to select patients for immunotherapy, such as EGRF, ALK and PD-L1 status in the tumors. We created a treatment protocol based on these 3 markers and treated 154 patients with non-small-cell-lung cancer in a Public Hospital in Brazil. The goal of this project is to identify the prevalence of these markers in the Brazilian population (to estimate patient eligibility), outcomes and costs of therapy.
A randomized parallel single-center clinical trial, blinded for the evaluation of the outcomes and statistical analysis. The current hypothesis is that PEAC-IC will improve self-care behavior, knowledge about heart failure, health-related quality of life, and the number of hospitalizations and searches for emergency services in the participants with heart failure.
A clinical, multicenter, randomized, parallel-group, double-blind, double-dummy, comparative study of non-inferiority. ⚠️Study will only be conducted in research centers in Brazil (please do not send e-mail if your center is outside brazil) .
Background: The control and maintenance of implants, bone tissue and soft tissue are fundamental for the clinical success of implant prostheses (PSIs). The type of ceramic surface finish can modify the biological response of peri-implant tissues adjacent to PSIs over time. Objective: To prospectively assess whether the peri-implant health of soft and hard tissues adjacent to monolithic zirconia PSIs varies with the type of surface finish (glazed or polished). It will also be evaluated if the patient perceives any clinical, comfort or satisfaction difference. Methodology: The study design is a randomized, prospective, paired clinical trial, with intra-subject comparison. The sample will consist of consecutive patients in need and indication for treatment with monolithic zirconia PSIs, attended at the Military Policlinic of Porto Alegre and in a private practice by a single specialist researcher. For each PSI, the allocation of a glazed or polished surface in contact with the soft gingival tissue will be randomized on the mesial and distal sides of the crown. Data will be collected by routine clinical and radiographic examination with a focus on peri-implant health (hygiene index, gingival bleeding index, crestal bone level), satisfaction questionnaire and intraoral images (thermography and photographs), after one week of installation of the PSI and in six months, one year and two years. The data will be analyzed by descriptive and inferential statistics, at the significance level of 0.05.
The aim of the present project is to evaluate functional, biological and technical variables, as well as quality of life and satisfaction as indicators of long-term clinical performance of single prostheses on short implants in the posterior region with a 10-year prospective follow-up. This proposal refers to a clinical research project with a 10-year follow-up of single crowns on short implants (6 mm) in the posterior region of the maxilla and mandible. The cohort has started in 2010 through a project funded by the International Team for Implantology. The main clinical results with a 4-year follow-up showed the influence of biomechanical factors (implant/crown ratio) on short-term treatment success and increased risk over time. The sample will consist of participants from the cohort of the research project established in 2010, who received a single crown on a short implant (6-mm Standard Plus Wide Neck SLA) in the posterior region of the maxilla or mandible according to eligibility criteria and standardized clinical procedures. Data will be collected by clinical and image exams, questionnaires (for sleep bruxism, satisfaction and quality of life), recording of maximum occlusal force, measurement of perimplant bone changes, and calculation of the clinical crown-implant ratio. Data will be analyzed by descriptive and inferential statistics with survival analysis and multivariable models, if assumptions are met, at the significance level of 0.05.
