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 project is a global, multicenter, prospective, longitudinal, observational natural history study that can be used to understand the disease progression and support the development of safe and effective drugs and biological products for Friedreich ataxia.
This study aims to evaluate the efficacy and safety of subcutaneous (SC) anifrolumab versus placebo in adult participants with cutaneous lupus erythematosus (CLE).
An evaluation of the molecular and epidemiological aspects of endometrial cancer in Brazil is necessary to understand the high frequency of advanced disease. A better understanding of the current situation will generate essential data for the future development of national or international cooperative programs that aim to improve outcomes in these patients and generate additional knowledge for much-needed clinical trials in this population.
This study will evaluate the clinical response and safety of ultrasound guided percutaneous cryoablation and a radiofrequency ablation in the treatment of benign thyroid nodules as an alternative to the surgery. Ablation of benign thyroid nodules with cryoablation will be directed to patients with benign thyroid lesions (two benign cytological examinations) measuring between 5 and 65 mL of volume and less than 40% of cystic component; patients must present with serum free thyroxine (T4) and thyroid stimulating hormone (TSH) between the normal range values, with no signs of thyroiditis by serum antibodies over 100% of the standard values; calcitonin levels in the normal range values. The cryoablation or RFA will be directed in a non-randomized fashion. Clinical, laboratorial and imaging monitoring will be performed in 12 months, including contrast-enhanced ultrasound when indicated, by 1, 3, 6 and 12 months.
This study is open to adults with a serious skin disease called generalized pustular psoriasis (GPP) who have repeated flares of GPP. The purpose of this study is to find out whether a medicine called spesolimab helps people with repeated flares of GPP. Participants are given a single dose of spesolimab as an infusion into a vein on the first day of an outbreak of GPP. They may be given a second dose 1 week later if doctors think it is helpful. They are also treated for additional GPP flares. During the time of the study, doctors regularly examine participants' skin for signs of GPP to see how well the treatment works and take blood samples. The doctors also regularly check participants' health and take note of any unwanted effects.
Alopecia areata (AA) is a disease that happens when the immune system attacks hair follicles and causes hair loss. AA usually affects the head and face, but hair loss can happen on any part of the body. The purpose of this study is to assess how safe, effective, and tolerable upadacitinib is in adolescent and adult participants with severe AA. Upadacitinib is an approved drug being investigated for the treatment of AA. In Study 1 and Study 2 Period A, participants are placed in 1 of 3 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 5 chance that participants will be assigned to placebo. In Study 1 and Study 2 Period B, participants originally randomized to upadacitinib dose group in Period A will continue their same treatment in Period B. Participants originally randomized to Placebo in Period A will either remain on placebo in Period B, or be randomized in 1 of 2 groups, based off of their Severity of Alopecia Tool (SALT) score. Participants who complete Study 1 or Study 2, can join Study 3 and may be re-randomized to receive 1 of 2 doses of upadacitinib for up to 108 weeks. Around 1500 participants with severe AA will be enrolled in the study at approximately 240 sites worldwide. Participants will receive oral tablets of either upadacitinib or placebo once daily for up to 160 weeks with the potential of being re-randomized into a different treatment group at Weeks 24 and 52. Participants will be followed up for up to 30 days after last study drug dose. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
Infections and reactivation of human cytomegalovirus (CMV), adenovirus, Epstein-barr and polyoma virus infections are frequent causes of morbidity and mortality and are a source of serious complications in patients undergoing allogeneic bone marrow transplantation. In this project we will prepare specific T lymphocytes from blood donor, select cells CMV-specific by interferon gamma capture and treat patients with CMV viral infections. These cells will be used as antiviral therapy in transplanted patients whom do not respond to conventional therapies or in patients whose conventional therapy may be toxic in the context of transplantation. In this context, CMV reactivation can lead to serious complications in patients, such as irreversible neurological changes, pulmonary, gastrointestinal and ophthalmologic complications, among others, in addition to prolonged hospitalizations, leading to significant morbidity and mortality , both in the health sector public as private. This project may represent an important therapeutic modality using cell of the shelf as a source of therapy for different patients and contributing to reduced morbidity / mortality after transplantation, as well as a reduction in the hospitalization period.
Phase 2/3 randomized and controlled clinical trial, which will evaluate the effectiveness of the association meglumine antimoniate (Glucantime) with tofacitinib in the cure of CL and the capacity of this association to reduce the time of cure of the disease.
This is a phase 3, randomized, placebo-controlled study of the efficacy and safety of MK-0616, an oral proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, in participants with high cardiovascular risk. The primary objective is to evaluate the efficacy of MK-0616 compared with placebo in increasing the time to the first occurrence of major adverse cardiovascular events (MACE) including coronary heart disease (CHD) death, ischemic stroke, myocardial infarction (MI), acute limb ischemia or major amputation, or urgent arterial revascularization.
The central objective of this study is to characterize the demographic of an ES-SCLC Brazilian cohort treated with durvalumab. Secondarily, to assess the outcomes of durvalumab-based regimens in 1L treatment of ES-SCLC Brazilian patients from the private health care setting.
