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 an efficacy and safety study of cosibelimab (CK-301) combined with pemetrexed/platinum chemotherapy versus pemetrexed/platinum chemotherapy alone in participants with advanced or metastatic non-squamous non-small cell lung cancer (NSCLC) who have not previously received systemic therapy for advanced disease. Participants will be randomly assigned in a 2:1 ratio to receive cosibelimab combined with pemetrexed/platinum (Investigators choice of cisplatin or carboplatin), OR pemetrexed/platinum (Investigators choice of cisplatin or carboplatin). The primary hypothesis is that cosibelimab in combination with pemetrexed/platinum chemotherapy prolongs Overall Survival (OS) compared to pemetrexed/platinum chemotherapy alone.
This is a Phase II, randomized, blinded, active-controlled, global, multicenter study designed to evaluate the safety and efficacy of lomvastomig and tobemstomig, compared with nivolumab, in patients with advanced or metastatic esophageal squamous-cell carcinoma (ESCC) refractory or intolerant to fluoropyrimidine- or taxane- and platinum-based regimen. Following approval of the protocol amendment version 3, recruitment into the lomvastomig arm has been stopped. The decision to stop recruitment for lomvastomig was based on strategic considerations and not based on emerging safety and/or efficacy data. The benefit/risk assessment for lomvastomig remains unchanged. The study was planned to enroll participants randomized in a 1:1:1 ratio to receive lomvastomig, tobemstomig, or nivolumab. With version 3 of the protocol, recruitment into the lomvastomig arm has stopped, and moving forward, participants will be randomized in a 1:1 ratio to receive either tobemstomig or nivolumab.
Chemotherapy induced nausea and vomiting are common adverse events related to oncologic treatments. It can have deleterious effect on patients' quality of life and could lead to dose reductions and/or discontinuation of treatment. This study aims to quantify the prevalence of nausea and vomiting induced by highly emetogenic chemotherapy in patients who had adequate antiemetic prophylaxis, also to describe the epidemiologic profile and identify predisposing factors.
The study will evaluate the efficacy and safety of trastuzumab deruxtecan (also known as T-DXd, DS-8201a), either alone or in combination with pertuzumab, in treating patients with Human epidermal growth factor receptor 2 (HER2)-positive breast cancer as a first line of treatment in the metastatic setting.
Introduction: Persistent hindfoot pains are very common and prevalent complaints in the Brazilian population. One of the treatments recommended for these conditions in the literature is the use of insoles. However, to use this resource it is necessary that the individual wear closed shoes and this is an obstacle to treatment in cities with hot climate. Thinking about an alternative treatment, the customized slippers with the corrective elements of the insoles can be an alternative to increase adherence to this type of treatment. Objective: To compare different types of hindfoot elements in insoles adapted in slippers in individuals with persistent hindfoot pain.
Treatment of patients hospitalised for management of moderate COVID-19 infection
Dopaminergic drugs partially alleviate gait problems in Parkinson's disease, but the effects are not sustained in the long-term. Particularly, the freezing of gait, balance problems and other gait issues directly impacts patients' quality of life. Experimental epidural spinal cord stimulation studies have suggested positive effects on locomotion among PD patients, but the effects of non invasive stimulation have never been explored.
The objective of this study is to compare the effects of two similar long-term interprofessional programs, one of them delivers by in-person classes, and another delivers by online classes on the quality of life of people with Parkinson's. Method: People with PD will be randomized into 3 groups: (1) Face-to-face group, in which participants, in groups of 10 persons, followed a multidisciplinary health education program composed of 10 monthly face-to-face lectures; (2) Remote group, in which individuals followed the same lectures delivered by online; and (3) Control group, in which participants followed no lecture. The participants will be evaluated before (BED) and after (ABP) the education program conclusion (10 lectures). Health quality of life was adopted as a primary outcome. Independence in daily living activities, motor and non-motor symptoms severity, and global cognitive capacity was adopted as secondary measures, Besides, all participants will be asked to answer a survey to evaluate the knowledge improvement of key learning points of lectures. The results will be analyzed by ANOVA for repeated measures.
Cardiovascular disease is the main cause of death worldwide. Endothelial dysfunction is the first step to development of cardiovascular diseases. Endothelial dysfunction occurs due to reduction in nitric oxide, a molecule that plays an important role on vascular health. Due to important role of nitric oxide in endothelial function, several studies have evaluated the effect of its precursors, such as L-citrulline and nitrate on endothelial function parameters. The present study will evaluate the effect of L-citrulline and nitrate derived by watermelon and beetroot products, respectively, on endothelial function of young and older participants. Furthermore, we will evaluate the plasmatic amino acids, nitrate, glucose and insulin in response to ingestion of these products.
The idea that the use of a wristband can increase the grip strength is old, but without systematic scientific evidence. Most Crossfit practitioners wear wrist bands during training because it is believed that the wristband increases the grip strength of the hand. The aim of this study is to to analyze the influence of the use of the wristband on the maximum force value and on the dynamic resistance of hand hold. A simple blind randomized cross-over trial will be performed.
