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.
Background: Recent reports increasingly recognize neurological manifestations in COVID-19 patients. However, the full spectrum of the disease and risk factors are not well understood. Aim: To describe the full spectrum of neurological manifestations in COVID-19 and assess the clinical characteristics, risks and prognostic factors. Outcomes: Identification of COVID-19 associated neurological disease is the primary outcome while requirement for admission to critical care unit, mortality, length of hospital stay, quality of life, and neurological disability are the secondary outcomes. Participants: Patients above Age more than 18 years enrolled based on new-onset acute neurological disease and COVID19 positive will serve as cases while patient with confirmed COVID-19 without neurological manifestation will serve as controls. Design and Procedures: The study is prospective case control in design and is divided into three phases in India, Brazil and Malawi ; the first phase will address role of hypoxia in causation of neurological diseases, the second phase will compare characteristics of patients hospitalized with COVID-19 with and without neurological disease and the third phase will assess the long-term follow up (at 3 months and 9 months) of cases.
This is a study for participants with a type of blood cancer called mantle cell lymphoma (MCL). The main purpose is to compare pirtobrutinib (LOXO-305) to other drugs that work in a similar way that have already been approved by the United States Food and Drug Administration (US FDA). Participation could last up to two years, and possibly longer, if the disease does not progress.
The disease promoted by coronavirus (COVID-19) is caused by Severe Acute Respiratory Syndrome (SARS) caused by Coronavirus type 2 (CoV2), being the first cases identified in December 2019 in China after exposure to the animal market in Wuhan city, China. From the first case to the present day, the COVID-19 epidemic has been identified in 185 countries, with the notification of 2,666,154 cases and 186,144 deaths. In Brazil, more than 45,757 cases and 2,906 confirmed deaths by COVID-19 have been confirmed (Visualized on Apr 23 2020). In our country, to date, testing for COVID-19 occurs only in severe cases and few centers offer the service to health care workers, a population at high risk of infection. BCG is a vaccine produced from a live attenuated strain derived from a Mycobacterium bovis isolate and is widely used worldwide as a tuberculosis (TB) vaccine, but there are studies demonstrating non-specific immunotherapeutic mechanisms of this vaccine that signal a possible relationship with the lowest morbidity and mortality associated with COVID-19 infections worldwide. The present study aims to analyze the role of BCG in the prevention of SARS-CoV-2 infection and also in the occurrence of severe forms of COVID-19 in addition to evaluating the immune response mediated by this vaccine in voluntary health care workers.
A higher prevalence of thyroid disease has been associated with chronic kidney disease (CKD), and subclinical hypothyroidism seems to be the most common dysfunction. The aim is to evaluate thyroid function and autoimmunity in patients with CKD stages 3, 4 and 5. Cross-sectional study to be carried out on patients with stages 3 and 4 in a Nephrology outpatient clinic. Thyroid function is evaluated by measuring thyroid stimulating hormone (TSH), free thyroxine, free triiodothyronine and antithyroperoxidase antibodies (TPOAb) levels.
The purpose of this study is to learn about the effects of three study medicines (encorafenib, binimetinib, and pembrolizumab) given together for the treatment of melanoma that: - is advanced or metastatic (spread to other parts of the body); - has a certain type of abnormal gene called "BRAF"; and - has not received prior treatment. All participants in this study will receive pembrolizumab at the study clinic once every 3 weeks as an intravenous (IV) infusion (given directly into a vein). In addition, half of the participants will take encorafenib and binimetinib orally (by mouth) at home every day. Participants may receive pembrolizumab for up to two years. Those participants taking encorafenib and binimetinib can continue until their melanoma is no longer responding. The study team will monitor how each participant is doing with the study treatment during regular visits at the study clinic.
This study will evaluate the efficacy, safety, and pharmacokinetics of DS-1062a versus docetaxel in participants with previously treated advanced or metastatic non-small cell lung cancer (NSCLC) with or without actionable genomic alterations.
This is a multi-center, parallel group treatment, Phase 2/3 open label study evaluating cobolimab in combination with dostarlimab and docetaxel in participants with advanced Non-small cell Lung Cancer (NSCLC) who have progressed on prior anti-PD-(L)1 therapy and chemotherapy.
This is a pivotal phase III study designed to evaluate safety, tolerability, and efficacy of inclisiran in adolescents with heterozygous familial hypercholesterolemia (HeFH) and elevated low density lipoprotein cholesterol (LDL-C).
The primary objective of the study is to estimate the clinical benefit of cemiplimab + ISA101b after progression on first line chemotherapy, as assessed by objective response rate (ORR). The secondary objectives of the study are: - To characterize the safety profile of cemiplimab + ISA101b - To assess preliminary efficacy of cemiplimab + ISA101b as measured by duration of response (DOR), progression-free survival (PFS), and overall survival (OS)
Primary Objective: - To evaluate the long-term safety of BIVV001 in previously treated subjects with hemophilia A Secondary Objectives: - To evaluate the efficacy of BIVV001 as a prophylaxis treatment. - To evaluate the efficacy of BIVV001 in the treatment of bleeding episodes. - To evaluate BIVV001 consumption for prevention and treatment of bleeding episodes. - To evaluate the effect of BIVV001 prophylaxis on joint health outcomes. - To evaluate the effect of BIVV001 prophylaxis on Quality of Life (QoL) outcomes. - To evaluate the safety and tolerability of BIVV001 treatment. - To assess the PK of BIVV001 based on the one stage activated partial thromboplastin time (aPTT) and two-stage chromogenic FVIII activity assays (only applicable to Arm B). - To evaluate the efficacy of BIVV001 for perioperative management
