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 longitudinal open-label study will include health professionals and patients with immune-mediated inflammatory diseases (IMID) who will receive the ChAdOx1 nCoV-19 vaccine (AZD1222), in a standard 3-dose schedule with an interval of 12 weeks (first-second dose) and 24 weeks (second-thrid dose), in the vaccination campaign against SARS-CoV-2 to assess the safety, efficacy and duration of the short- and long-term humoral and cellular immune response after vaccination for COVID-19 and compare the vaccine response between individuals who have or have not had previous SARS-Cov 2 infection.
This study is being done to see if tucatinib works better than placebo when given with other drugs to treat participants with HER2-positive breast cancer. A placebo is a pill that looks the same as tucatinib but has no medicine in it. This study will also test what side effects happen when participants take this combination of drugs. A side effect is anything a drug does to the body besides treating your disease. Participants will have cancer that has spread in the body near where it started (locally advanced) and cannot be removed (unresectable) or has spread through the body (metastatic). In this study, all participants will get either tucatinib or placebo. Participants will be assigned randomly to a group. This is a blinded study, so patients and their doctors will not know which group a participant is in. All participants will also get trastuzumab and pertuzumab. These are 2 drugs used to treat this type of cancer.
This trial will evaluate efficacy, safety, and tolerability of subcutaneous (s.c.) ianalumab given every 4 weeks (q4w) or every 12 weeks (q12w) compared to placebo, in combination with SoC, in adult participants with active LN
Pectus excavatum (PE) is the most common congenital deformity of the chest wall and surgical treatment using the minimally invasive technique (MIRPE) is consolidating as the choice to perform PE correction. In this technique, a temporary metal bar is placed in a retrosternal position, pushing the sternum without the need for cartilage resection. Despite the advantages obtained, it is not free from complications, with the displacement of the bar being one of the main problems. Therefore, the aim of this study is to evaluate a new bridging device for the set of two metal bars to be used in the surgical treatment of PE, verifying the clinical and surgical complications and evaluating the change in lung volumes and thoracoabdominal kinematics using optoelectronic plethysmography , preoperatively and 180 days after MIRPE; and also evaluating diaphragmatic mobility via ultrasound examination to assess the craniocaudal displacement of the left branch of the vein preoperatively and 180 days later. There will be 20 participants, who after performing a computed tomography of the chest to obtain the Haller index, clinical and laboratory tests, electrocardiogram and echocardiogram. Participants will be randomized and divided into two groups: 10 control individuals (traditional MIRPE technique used in the Service) and 10 intervention individuals (with bridge fixators developed in partnership with Traumec Tecnologia e Implantes, Brazil). The effectiveness of the fixators will be evaluated by the degree of displacement of the bars, using a mathematical formula, using a lateral chest X-ray in the immediate postoperative period (d0) and another image from the end of the period analyzed (dX), 15, 30, 90 and 180 days after the surgical procedure; evaluation of postoperative pain through the numerical pain scale; use of validated questionnaires on quality of life (physical and mental health) using two instruments, SF-36 and PEEQ. All data obtained between the two groups will be submitted to descriptive and inferential statistics.
This double-blind, double-dummy study will evaluate the safety and efficacy of ocrelizumab compared with fingolimod in children and adolescents with relapsing-remitting multiple sclerosis aged between 10 and < 18 years over a duration of at least 96 weeks.
Rationale: The interaction between nonvitamin K oral anticoagulants (NOACs) and platelet aggregation is complex. The direct activated factor X inhibitors (factor Xa inhibitors) an NOAC antagonizes thrombin generation, one of most important platelet agonist, so that, factor Xa inhibitors has a potential effect in decreasing thrombin-mediated platelet aggregation. On the other hand, patients who experience ACS continue to have a hypercoagulable state for long periods after the index event. The COMPASS trial showed that, in patients with stable coronary artery disease (SCAD), Rivaroxaban (a direct anti-Xa inhibitor) in addition to antiplatelet agent, compared to antiplatelet therapy alone, reduced the composite endpoint of myocardial infarction, stroke and death. Objective: Analyze the role of edoxaban on platelet aggregation in SCAD patients. Methods and Results: This is a prospective, non-randomized, interventional study of SCAD patients taking low-dose acetylsalicylic acid (ASA). Subjects initially will receive in the following sequence: ASA 100 mg once daily (QD) plus edoxaban 60 mg QD, clopidogrel 75 mg QD alone, clopidogrel 75 mg QD plus edoxaban 60 mg QD, and edoxaban 60 mg QD alone. Platelet function will be assessed by standard of care technology, at baseline and after each intervention phase, by Multiplate-ADP® (primary endpoint), Multiplate-Aspi® and Multiplate-TRAP®. In addition to immature platelets fraction (% IPF) and count (IPC). Coagulability will be assessed, at baseline and after each intervention phase, by thromboelastogram (TEG) assessment. Specifically, after the phases in which edoxaban will be administered activated factor X (FXa) level and Plasminogen activator inhibitor-1 (PAI-1) will be evaluated in addition to previous. Finally, inflammatory markers will be, at same way, assessed at baseline and after intervention each phase: ultrasensitive C-reactive protein (us-PCR). Keywords: edoxaban, direct factor Xa inhibitor, stable coronary artery disease, aspirin, clopidogrel, platelet aggregation.
This is a global study to assess the effects of osimertinib in participants with EGFRm stage IA2-IA3 non-small cell lung cancer following complete tumour resection.
Periodontitis is a chronic and destructive inflammation that leads to the loss of tissue supporting the teeth, the periodontium, and possibly tooth loss and edentulism. Its etiology is related to an overload on the host's defense mechanisms, consequent to the accumulation of plaque or suppression of the immune system. Standard treatment for periodontitis includes scaling and root planing (RAR) and possible association with therapeutic adjuvants such as systemic and local antimicrobials. However, the use of these drugs supporting the treatment of periodontitis, has shown adverse effects such as loss of taste, soft tissue burn, pain, xerostomia, supragingival calculus formation and change in staining of teeth, restorations, prostheses and tongue. Other effects not as common as mucosal ulcerations, desquamative lesions, urticaria, dyspnea, anaphylactic shock and swellings reversible effects in the parotid glands and lips have also been observed and reported in the literature. Thus, there is a need for new adjuvant therapies, which cause less effects side effects and that are more effective in the treatment of periodontitis and in the maintenance of oral health. The commercial product PHTALOX® is a phthalocyanine dental mouthwash that has a spectrum of action based on the formation of reactive oxygen that acts by inhibiting odor-causing substances, on microorganisms and on the mechanisms of coagulation and healing. Your supporting action in periodontal treatment may have promising potential. Thus, the purpose of this study clinical trial will be testing a formulation containing PHTALOX® for disease prevention and control Periodontal (PD). 30 patients will be recruited who will undergo scaling and straightening coronaroradicular (RAR), and after basic periodontal treatment will be randomly divided into 3 groups according to the supporting treatment: G1 - patients who will receive mouthwashes with physiological solution; G2 - patients who will receive 0.12% chlorhexidine mouthwash; G3 - patients who will be treated with PHTALOX®. Clinical reassessments of patients will be carried out before the treatments, and at 15, 30 and 60 days after the performance of the RAR and beginning of the respective mouthwash. After data collection, intra and intergroup analyzes will be performed comparing the therapeutic results for the periodontal condition through the "Bioestat" program.
In order to increase adherence to ketogenic diet treatment, palatability of meals and diversify the foods offered to patients a ketogenic kitchen will be created.
