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 is a longitudinal, prospective study, which will include 30 subjects with hereditary coagulopathies, with arthropathy, chronic synovitis resulting from hemarthrosis of the elbows, knees and/or ankles followed up at the Centro de Hemofilia HCFMUSP, after approval by the ethics and research committee. They will undergo imaging tests (X-rays and Magnetic Resonance of knee, elbow, or ankle), physical, pain, quality of life and functional assessments (Hemophilia Joint Health Score, Functional Independence Score in Hemophilia, Perimeter, Test Timed up and Go, 30 second sit and stand test, Haemophilia - Adult - Quality of Life questionnaire (HAEM-A-QoL), Knee Injury and Osteoarthritis Outcome Score, EQ-5D, numerical rating scale for pain and embolization procedure (superselective embolization of target arteries with spherical microparticles Embosphere 100-300 micrometers (Biosphere Medical, Roissy, France), until partial vascular stasis and decharacterization of pathological synovial enhancement. These evaluations will be performed at baseline, 1, 3, 6, 12, 24, 36, 48 and 60 months after the procedure.
The goal of this observational patient registry is to learn how expert centers treat patients with chronic thromboembolic pulmonary hypertension (CTEPH). CTEPH is a condition in which blood clots block the blood vessels in the lungs. There are currently three treatment options for patients with CTEPH: - surgery to remove blood clots from large vessels in the lungs (pulmonary endarterectomy (PEA)) - the use of a small balloon to unblock smaller blood vessels (balloon pulmonary angioplasty (BPA)) - drugs Patients can also receive a combination of these treatments. The main question this registry aims to answer are: - How many patients receive a given kind of treatment? - How do expert centers combine the different treatments? - Are patients doing better after they receive a given kind of treatment? - How many patients are alive 1, 3 and 5 years after they receive a given kind of treatment? Participants will receive the same treatments that they would receive if they did not participate in the study. During the study, patients will visit their doctors as they would do normally. The doctors will collect information on the patients' health and enter it into the study database. The follow-up time will be at least 3 years for all patients.
This open-label, randomized multicenter study is to assess the efficacy, safety, and pharmacokinetics (PK)/pharmacodynamics (PD) of obinutuzumab compared with mycophenolate mofetil (MMF) in children and young adults (aged >= 2-25 years) with frequently relapsing nephrotic syndrome (FRNS) or steroid-dependent nephrotic syndrome (SDNS).
Skeletal muscle fatigue is an inevitable phenomenon in the training and competition routine for many crossfit athletes, which can impair their physical performance and predispose them to musculoskeletal injuries. Thus, strategies and/or therapies that minimize fatigue and accelerate muscle recovery are extremely relevant for everyone involved with sport. The aim of the present study is to investigate and compare the effects of photobiomodulation, cryotherapy combined with compression, and massage as isolated therapies for muscle recovery after a protocol of induced muscle damage and fatigue in Crossfit athletes. This is a randomized, double-blind, crossover, sham-controlled clinical trial. Will be recruited 60 male participants, adults, aged between 18 and 40 years, Crossfit practitioners. They will be randomly allocated into 3 groups of 20 participants per therapy, each crossed between effective and sham every 15 days. The primary outcome will be muscle performance in functional test (free squat) and knee extensor torque in maximal voluntary isometric contraction (MVIC). Secondary outcomes will be evaluated by the levels of muscle damage via creatine phosphokinase (CPK) and inflammatory process via blood C-reactive protein (CRP); and delayed onset muscle pain via numerical verbal scale (0-10). All outcomes will be evaluated at baseline, 24h and 48h after induction of muscle damage and fatigue. Data will be analyzed and compared intra and inter groups with a significance level of 5%.
The aim of this study will be to evaluate the non-inferiority of implants produced by additive manufacture loaded in 30 days when compared with those loaded in 90 days, in relation to marginal bone loss, after 01 (one) year of follow-up
The primary reason of this study is to observe current and past treatment in adult participants receiving Vedolizumab, intravenous (IV) or subcutaneous (SC), for IBD in Brazil. There is no treatment involved in this study, this is only an observational review of past and ongoing treatment data relating to Vedolizumab treatment for IBD (including Ulcerative Colitis [UC] and Crohn's Disease [CD]).
Drug-eluting stent (DES) implantation as interventional strategy for lesions in small coronary arteries is the current standard of care in many centers worldwide, but is associated with increased risk of late treatment failure in small vessels, as compared with larger coronary arteries. Randomized and observational studies have been shown that coronary intervention with drug-coated balloons (DCB) provide a promising alternative to DES implantation in small vessels, while avoiding the risk of a permanent vascular implant. Furthermore, lesions in small vessels are frequently concomitant with diffuse disease and/or distal location, where the presence of calcification is an additional common feature. Intravascular lithotripsy (IVL) has been recently introduced as a novel adjunctive technology to treat calcified lesions. This study will explore the hypothesis that IVL has the potential to enhance the results of coronary balloon dilatation of small vessels with calcified lesions, therefore increasing the likelihood of optimal DBC intervention.
The purpose of this study is to demonstrate that the study drug exposure level of the nivolumab + relatlimab FDC subcutaneous (SC) formulation is not worse than nivolumab + relatlimab FDC intravenous (IV) administration in participants with previously untreated metastatic or unresectable melanoma.
The purpose of this study is to evaluate the efficacy and safety of nemtabrutinib compared to investigator's choice of fludarabine plus cyclophosphamide plus rituximab (FCR) or bendamustine plus rituximab (BR) in participants with previously untreated CLL/SLL without 17p deletion and/or tumor protein (TP) 53 mutation. The primary hypothesis is that nemtabrutinib is superior to FCR/BR with respect to progression-free survival (PFS).
The purpose of this study is to evaluate the effect of tozorakimab, as an add-on to SoC in patients with viral lung infection requiring supplemental oxygen, on the prevention of death or progression to IMV/ECMO.
