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 COVID-19 pandemic has been characterized by high morbidity and mortality, especially in certain subgroups of patients. To date, no treatment has been shown to be effective in patients with early-onset disease and mild symptoms. Experimental studies have demonstrated a potential anti-inflammatory role of Fluvoxamine, Fluoxetine, Budesonide and Spirulin Platensis in SARS-CoV-2 infections and observational studies have suggested a reduced complications in patients with COVID-19 disease.
This research investigates how cognitive-affective aspects evolve during the course of SCA3/MJD. Due to COVID-19 pandemics, this study protocol was adapted for online-only consultations. Evaluations happening after March 2020 have been done by videocall with patients, and no neurological evaluation was thus performed on these patients. A scale on Activities of Daily Living was added to the online protocol to replace SARA, SCAFI and CCFS scales.
This study will evaluate the associations between vascular parameters and clinical outcomes in patients hospitalized with COVID-19. The vascular function and structure of individuals with COVID-19 admitted to the General Hospital of the University of Sao Paulo will be assessed in the first 72 hours of hospitalization. Then, participants will be followed up until hospital discharge/death. Logistical regressions will be run to evaluate if vascular function/structure can predict ICU admissions, intubation, thrombosis or death.
Clinical, control, double-blind, randomized trial with tenofovir disoproxyl fumarate and emtricitabine for Covid-19
This study will evaluate the efficacy and safety of mosunetuzumab in combination with lenalidomide (M + Len) compared to rituximab in combination with lenalidomide (R + Len) in participants with relapsed or refractory (R/R) follicular lymphoma (FL) who have received at least one line of prior systemic therapy.
Sickle cell anemia (SCA) is one of the most neglected diseases worldwide, according to the World Health Organization. In the adult population with SCA, the systemic effects of the disease, such as respiratory and peripheral muscle dysfunction, cause a decrease in quality of life. As a consequence, there is a concern about functional rehabilitation, since the aging of this population is already a reality in our environment. Thus, the objective of this project is to evaluate the effects of functional rehabilitation on quality of life in adult patients over 18 years of SCA. In this longitudinal intervention study, patients will be submitted to a three-month rehabilitation program. Before and after the intervention, patients will be submitted to the following assessments: spirometry; quality of life questionnaire - Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36); functional scale of joint integrity - Lower Extremity Functional Scale (LEFS); fatigue assessment scale - Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F); physical activity assessment questionnaire - International Physical Activity Questionaire (IPAQ); peripheral muscle assessment (handgrip and isometric dynamometry of the quadriceps muscle); and 6-minute walk test (6MWT). The protocol will consist of warm-up and cool-down exercises, muscle strengthening and endurance exercises, aerobic training, balance training and proprioception. Thus, it is expected that patients with sickle cell anemia will benefit significantly, with a consequent improvement in musculoskeletal function, pain and health-related quality of life.
This study will evaluate the efficacy and safety of trastuzumab deruxtecan (T-DXd) compared with ramucirumab and paclitaxel (Ram + PTX) in participants with HER2-positive gastric or gastro-esophageal junction (GEJ) adenocarcinoma who have progressed on or after a trastuzumab-containing regimen and have not received any additional systemic therapy.
This is a single-arm, multicenter open label, international, phase II study of Bipolar Androgen Therapy (BAT) plus Radium-223 (RAD) in men with metastatic castration-resistant prostate cancer (mCRPC). Men with mCRPC with progressive disease (radiographically and/or biochemically) who have been treated with gonadotropin-releasing hormone (GnRH)-analogue (LHRH agonists/antagonists) continuously or bilateral orchidectomy will be enrolled in this study. Previous antiandrogen therapies are permitted, but no more than one (such as abiraterone, enzalutamide, apalutamide, darolutamide). All patients will receive treatment with Radium-223 at a dose of 55 Kilobecquerel (kBq) per kilogram of body weight IV every 28 days, for 6 cycles, plus Testosterone Cypionate 400mg Intramuscular (IM) every 28 days, until progression or unacceptable toxicity.
The WE-TRUST study is a multi-center randomized clinical trial to assess the impact of a Direct to Angio Suite (DTAS) workflow on stroke patient outcomes.
Randomized phase 2 trial to evaluate the efficacy of local therapy for oligometastasis from ER/PR-positive breast cancer. The study hypothesis is that local therapy in addition to systemic therapy improves progression-free survival in comparison with systemic therapy alone.
