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 primary objective of this study is to assess the long-term safety of vatiquinone in participants with Friedreich ataxia (FA) previously exposed to vatiquinone.
The main purpose of this study is to measure how well imlunestrant works compared to standard hormone therapy in participants with early breast cancer that is estrogen receptor positive (ER+) and human epidermal receptor 2 negative (HER2-). Participants must have already taken endocrine therapy for two to five years and must have a higher-than-average risk for their cancer to return. Study participation could last up to 10 years.
The purpose of this extension study is to collect long-term efficacy, safety and tolerability data on remibrutinib in a selected group of participants with Chronic Spontaneous Urticaria (CSU) who previously completed the treatment phase of remibrutinib preceding Phase 3 studies. This study will also fulfill the Novartis commitment to provide post-trial access to participants who have completed the preceding Phase 3 studies, where applicable.
This project aims to investigate the effects of an intervention involving minimalist piano music and bird singing on the anxiety of nursing professionals working in the Oncology sector of a hospital.
Study participants will be screened during the platform study and randomly assigned to receive mirikizumab or another intervention. The purpose of the mirikizumab study is to evaluate efficacy, safety, tolerability, and how well mirikizumab absorbs into the body of pediatric participants with Crohn's disease. Study periods for the intervention-specific appendix (ISA) will be as follows: - A 12-week induction period - A maintenance period from Week 12 to Week 52, and - A safety follow-up period up to 16 weeks. The study will last about 74 weeks and may include up to 19 visits.
The purpose of this study is to compare efficacy of coformulated favezelimab/pembrolizumab (MK-4280A) with physician's choice chemotherapy of bendamustine or gemcitabine in participants with PD-(L)1-refractory, relapsed or refractory classical Hodgkin Lymphoma. The study will also assess the safety and tolerability of coformulated favezelimab/pembrolizumab. The primary study hypotheses are that coformulated favezelimab/pembrolizumab is superior to physician's choice chemotherapy with respect to progression-free survival (PFS) and overall survival (OS).
Evaluate the potential of Primary Dermal Irritability, Accumulated Dermal Irritability and Dermal Sensitization, of health products through the application of Patch Test, proving the safety of the product for topical use. The study will be conducted with a Brazilian sample in which 65 research participants will be included. Depending on the results, the present study may support the claim: dermatologically tested.
This is a clinical study for health care product safety assessment. The research is going to conducted with 45 subjects, aged 18 to 70 years, women users of the product category, regardless of color/race, ethnicity, sexual orientation, classes and social groups and who must present all the other characteristics of the inclusion criteria and no exclusion characteristics. The product is applied under real conditions of use, in a panel of survey participants corresponding to the target consumers. Medical evaluation will be available throughout the study to assess possible adverse events. The main of the study is to observe the effects of the application of the product on the skin and prove the absence of irritability and/or allergy and perceived acceptability.
Clinical trial with randomized allocation in two arms (BCG vaccine versus placebo) of volunteers at risk but not yet infected nor vaccinated against SARS-CoV-2. Initially will be evaluated whether BCG has a protective role against severe form of the disease. After participants are vaccinated against COVID-19, it will be evaluated whether BCG favors the vaccine's efficacy. Volunteers will be recruited in three Brazilian states, with at least 250 seronegative in each group. The BCG-trained immunity stimulus will be investigated by assessing cytokines at D0 and D60 in a subsample of 50 participants per group. Until being vaccinated against COVID-19, the participants will be followed for up to 6 months, with visits scheduled every 2 months for interviews and immunoglobulin G (IgG) anti-SARS-CoV-2 antibodies. Those who become symptomatic at any time during the follow-up will be guided and monitored remotely daily until the end of their clinical evolution. After being vaccinated against COVID-19, visits to participants will be adjusted for the time of vaccination (VD), 20 days after the 1st dose (P1) and at least 30 days (P2) after the 2nd dose, with the aim of comparing the efficacy of the anti-SARS-CoV-2 vaccine in the two groups in the short and medium term. The study's conclusions on the efficacy of BCG in preventing severe COVID-19 will be based on: incidence of SARS-Cov-2 infection (defined as the emergence of IgG over the follow-up period); incidence of illness by COVID-19 (defined as the presence of symptoms among infected participants); intensity and duration of symptoms between cases of COVID-19 and frequency and duration of hospitalizations for COVID-19 in each group. The occurrence, type, frequency and intensity of adverse effects associated with vaccination of adults with BCG will be reported. The study's conclusions regarding the effect of BCG on efficacy of vaccines against COVID-19 will be based on: frequency of anti-SARS-CoV-2 neutralizing antibodies after the vaccine' 1st and 2nd doses in both groups.
This is a multicenter, randomized, placebo controlled study to evaluate the efficacy and safety of ABX464 given at 25 or 50 mg QD in inducing clinical remission in subjects with moderately to severely active ulcerative colitis who have inadequate response, no response, a loss of response, or an intolerance to either conventional therapies [corticosteroids, immunosuppressant (i.e. azathioprine, 6-mercaptopurine, methotrexate)] and/or advanced therapies [biologics (TNF inhibitors, anti-integrins, anti-IL-23), and/or S1P receptor modulators, and/or JAK inhibitors].
