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 the study is to compare longitudinally the clinical performance of dental implants with different surfaces placed in single tooth gaps at the posterior maxilla and mandible of adults. It is a randomized clinical trial, in which participants will be randomly allocated to two groups: test group (implants with hydrophilic surface) and control group (implants with hydrophobic surface). The null hypothesis is that the implant stability quotient of hydrophilic and hydrophobic dental implants show a similar progression after placement in posterior tooth gaps.
This study is open to adults with COVID-19 infection who are in hospital and receive oxygen. Participants need to be 50 years of age or older and need to be at risk of further worsening of their condition. The purpose of the study is to find out whether a medicine called BI 764198 helps people with COVID-19 infection and breathing problems. BI 764198 may prevent cell death and swelling of the lung tissue and therefore help patients with COVID-19 infection. Participants are put into 2 groups by chance. One group of participants gets BI 764198 capsules and the other group gets placebo capsules. The placebo capsules look exactly like the BI 764198 capsules but do not contain any medicine. Participants take 1 capsule per day. Participants are in the study for about a month. At study end, doctors compare the 2 groups for the number of patients that are alive and do not need mechanical breathing support. During the study, the doctors collect information on any health problems of the participants.
The purpose of this study was to evaluate the efficacy of derazantinib monotherapy or derazantinib in combination with paclitaxel and ramucirumab in patients with gastric adenocarcinoma (GAC) i.e. with human epidermal growth factor receptor 2 (HER2)-negative adenocarcinoma of the stomach or gastro-esophageal junction harboring fibroblast growth factor receptor 2 (FGFR2) genetic aberrations (GA).
COVID 19 has become a pandemic and has led to high demand on healthcare systems. It can cause a severe acute respiratory syndrome (SARS CoV-2) which leads to a long hospital stay, developing important functional damage and making hospital discharge difficult. Elderly, obese and people with chronic diseases are more susceptible to contracting the disease, this profile of patients already has a predisposition for respiratory muscle weakness and in this context, after clinical stability, it is still necessary in a hospital environment to approach respiratory and motor physiotherapy. to optimize the recovery of these patients. Objective: Improved breathing, functionality, exercise capacity and muscle strength in non-critical patients. Method: Prospective randomized clinical study where one group received motor and respiratory physiotherapy and the other group performed the same therapy associated with inspiratory muscle training. Results: The findings will be compared before and after the approach and will be presented in graphs and tables. Statistical tests will be used considering a significance level of 5%.
The study will compare the efficacy and safety of entrectinib with crizotinib in participants with advanced or metastatic ROS1 non-small cell lung cancer (NSCLC). The participants will self-administer oral entrectinib or crizotinib as described in the protocol and local prescribing information. Treatments will continue until progressive disease, unacceptable toxicity, death, or withdrawal from the study, whichever occurs first.
The purpose of this study is to evaluate the efficacy and safety of Berlim 25/20 association in the treatment of type 2 diabetes mellitus and dyslipidemia.
Double-blinded, placebo control, randomized, phase-3 clinical trial to evaluate clinical efficacy of Favipiravir in patients with mild to moderate symptoms related to COVID-19 infection
Chocolate is a widely appreciated foodstuff with historical appreciation as food from the gods. It is a rich source of (poly)phenolics, which have several proposed salutogenic effects, including neuroprotective anti-inflammatory, antioxidant, and cardioprotective properties. This study will evaluate the potential salutogenic contribution of chocolate intake, to mitigate inflammatory and oxidative burden in chronic kidney disease patients.
The COVID-19 infection primarily manifests itself as a respiratory tract infection, although new evidence indicates that this disease has systemic involvement involving multiple systems including the cardiovascular, respiratory, gastrointestinal, neurological, hematopoietic and immune systems. Recent studies have shown that in its pathophysiology, inflammation and thrombogenesis predominate, especially in the severe forms of COVID-19. Thus, the investigators hypothesized that the use of heparin and tocilizumab could potencially reduce inflammation and thrombogenesis in patients with severe COVID-19 infection, improving patients outcomes and survival.
Prospective, interventionist, controlled and randomized study to test the effectiveness of a multimodal prehabilitation protocol in patients who will undergo gynecological surgery.
