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.
A study designed to evaluate the non-inferiority of crovalimab compared with eculizumab in participants with PNH who have not been previously treated with complement inhibitor therapy.
This is a Phase IIIb, multicenter, open-label, single-arm study of prophylactic emicizumab in previously untreated and minimally treated patients at study enrollment from birth to ≤12 months of age with severe hemophilia A (intrinsic factor VIII [FVIII] level <1%) without FVIII inhibitors. The study is designed to evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamics of emicizumab administered at 3 milligrams per kilogram of body weight (mg/kg) once every 2 weeks (Q2W) for 52 weeks. After 1 year of treatment, participants will continue to receive emicizumab (1.5 mg/kg once every week [QW], 3 mg/kg Q2W or 6 mg/kg once every 4 weeks [Q4W]) over a 7-year long-term follow-up period under this study frame.
The study will consist of a prospective observation of subjects in a natural history design. The investigators will monitor changes of clinical scales, quality of life, messenger ribonucleic acid (mRNA) of candidate genes (CCL11, TNFSF14, FCGR3B, CLC, and SLA) (and their peptide products, when possible), and eotaxin and S100B serum levels, in order to determine which of them is (are) the most sensitive. Participants will be stratified in three groups: ataxic carriers, pre-ataxic carriers and non-carriers (controls).
Primary Objective: To assess efficacy of daily SAR442168 compared to a daily dose of 14 mg teriflunomide (Aubagio) measured by annualized adjudicated relapse rate (ARR) in participants with relapsing forms of MS Secondary Objective: To assess efficacy of SAR442168 compared to teriflunomide (Aubagio) on disability progression, MRI lesions, cognitive performance and quality of life To evaluate the safety and tolerability of daily SAR442168 To evaluate pharmacodynamics (PD) of SAR442168
The Açaí trial will be testing if the açaí berry extract, a safe natural product with anti-inflammatory properties, can be used as a treatment option in adult patients with COVID-19 in the community.
Myelodysplastic Syndrome (MDS) is a group of disorders that gradually affect the ability of a person's bone marrow (semi-liquid tissue present in many bones like backbones) to produce normal blood cells. Some people with MDS have a risk of the disease progressing to acute myeloid leukemia (AML), and a risk of death from the disease itself. Symptoms of MDS include fatigue, shortness of breath, unusual paleness due to anemia (low red blood cell count), easy or unusual bruising, and red spots just beneath the skin caused by bleeding. The purpose of this study is to see how safe and effective venetoclax and azacitidine (AZA) combination are when compared to AZA and a placebo (contains no medicine), in participants with newly diagnosed higher-risk MDS. Venetoclax is an investigational drug being developed for the treatment of MDS. The study consists of two treatment arms - In one arm, participants will receive venetoclax and AZA. In another arm, participants will receive AZA and placebo. Adult participants with newly diagnosed higher-risk MDS will be enrolled. Around 500 participants will be enrolled in approximately 220 sites worldwide. Participants in one arm will receive oral doses of venetoclax tablet and intravenous (infusion in the vein) or subcutaneous (given under the skin) AZA solution. Participants in another arm will receive oral doses of placebo tablet and intravenous or subcutaneous AZA solution. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood and bone marrow tests, checking for side effects, and completing questionnaires.
TAK-981 is being tested in combination with pembrolizumab to treat participants who have select advanced or metastatic solid tumors. The study aims are to evaluate the safety, tolerability, and preliminary efficacy of TAK-981 in combination with pembrolizumab. Participants will be on this combination treatment for 21-day cycles. They will continue with this treatment for up to 24 months or until participants meet any discontinuation criteria.
C3731003 is a pivotal Phase 3 study to evaluate the clinical efficacy and safety of a single IV infusion of PF-07055480 / giroctocogene fitelparvovec (Recombinant AAV2/6 Human Factor VIII Gene Therapy) in adult male participants with moderately severe or severe hemophilia A (FVIII:C≤1%) for the study duration of 5 years. The study will enroll eligible participants who have been followed on routine prophylaxis with FVIII products in the Lead-In study C0371004.
Home visiting programs for pregnant women aiming to improve mother-infant relationship has received worldwide attention in the past 30 years. These programs are considered an important strategy to improve women's health during pregnancy, aside from improving child's birthing conditions and allowing parents access to tools which will nurture and properly stimulate their baby, thus promoting emotional and cognitive development. Objectives: The "Nurse home visitation program for pregnant youth" aims to promote infant´s healthy development, from pregnancy to the first months of life, in a high-risk population. Methods: Eighty young pregnant women aged between 14 and 21 years were randomly allocated to the intervention or to usual prenatal care program. The "Nurse home visitation program for pregnant youth" was developed based on Albert Bandura's theory of self-efficacy, on Urie Bronfenbrenner´s bioecological model, which recognizes the importance of individual and family inclusion in various contexts of social life, on John Bowlby and Mary Ainsworth evolutionary theories of attachment, which involves the care practitioner addressing issues such as environmental health, life course and parenting, bond between mother and infant, and infant´s social and cognitive development. Neuropsychomotor development will be assessed at 3, 6, 12 and 24 months using the Bayley Scale of Infant Development. Brain development will be assessed via electroencephalography at 6, 12 and 24 months.
This is an observational study, meaning that no interventions is tested, to determine incidence of SARS-CoV-2 infection and COVID-19 in different clinical sites in Brazil in several age groups. The study aims to assess baseline number of infected participants and perform a follow-up along two years to determine the new cases occurring among participants during the period. All participants will collect blood samples to get more details on the immune response.
