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.
Intraoperative methadone or fentanyl will be administered to patients submitted to kidney transplant surgery. Postoperative pain, analgesic consumption and side effects will be evaluated
This is a phase 3, single arm, open-label study evaluating the effectiveness of TOL2506 to suppress ovarian function in premenopausal women with HR+, HER2-negative breast cancer. The study will also aim to assess the safety of TOL2506 in men with HR+, HER2-negative breast cancer. The Screening Period will be conducted in two parts: 1) an abbreviated, initial screening where premenopausal status will be determined prior to neoadjuvant or adjuvant chemotherapy (if planned) and 2) the full screening assessment conducted after neoadjuvant or adjuvant chemotherapy (or for subjects who enter the study without having received chemotherapy). Following the Screening Period, eligible subjects will enter into the 48 week Treatment Period in 1 of 2 groups: those who will receive tamoxifen concurrently with TOL2506 or those who will initiate therapy with an AI (letrozole, anastrozole, or exemestane) beginning 6 weeks after the first administration of TOL2506, upon confirmation that estradiol (E2) levels of < 20 pg/mL (testosterone levels < 50 ng/dL in males) have been achieved. After Week 12, subjects will be allowed to switch from receiving an AI to receiving tamoxifen or from tamoxifen to AI at the discretion of the Investigator. However, a switch is not permitted 28 days prior to a dosing visit (eg, Week 24, 36, and 48 where a pre-dose blood sample for PK and PD analysis will be drawn). At the end of the Treatment Period, upon completion of the End of Study Visit (Visit 9, Week 48) subjects may be eligible to participate in a Safety Extension Study under a separate Protocol.
Introduction: The genitourinary menopause syndrome (MMS) affects 50% of postmenopausal women and, due to a decrease in hormone levels, triggers functional changes in the vagina and vagina, and impairment of quality of life and sexual function. Objective: To test the hypothesis that the 405 nm light emitting diode in the treatment of vulvovaginal atrophy is safe and effective, by reducing the symptomatology of the disease and histological alteration of the tissue. Methods: This is a pilot study in 10 volunteers with SGM, followed by a randomized, blinded trial in a sample of 58 individuals that will be performed at the Pelvic Floor Care Center (CAAP). Menopausal women up to 65 years of age and with clinical signs and symptoms of vulvovaginal atrophy syndrome (vaginal dryness and irritation, pruritus, pain or discomfort in intercourse, bleeding after sexual intercourse) and who voluntarily participate in the study will be included. Will be excluded from the study the patients in hormonal replacement for less than 6 months, diagnosis of vaginal infection, use of pacemaker, pregnant women, those who have performed Oophorectomy or presented ovarian cancer, difficulty understanding the proposed instruments and patients with chronic neurological degenerative diseases. Three 405 nm light emitting diode (LED) sessions will be performed, with a seven days interval between them. In the clinical trial, the study group will perform kinesiotherapy and LED. The control group will perform kinesiotherapy and the LED will be turned off. Data collection will be performed initially and after the sessions through self-administered questionnaires containing socio-demographic and clinical information, Medical Outcomes Study 36, Short-Form Health Survey (SF-36), Female Sexual Function Index (FSFI) - Female Version (QS-F), Female Genital Self-Image Scale - 7 (FGSIS-7). At the end of treatment, the visual analog scale and Likert scale will be used to measure the individual's satisfaction. Expected results: The 405nm LED in the vaginal canal is expected to be safe and effective for SGM.
The purpose of this study is to evaluate the effectiveness, safety and tolerability of Afimetoran in participants with active Systemic Lupus Erythematosus (SLE). The extension period will provide additional long-term safety and efficacy data and enable those participants initially randomized to placebo to receive treatment with Afimetoran.
Chronic lymphocytic leukemia (CLL) is the most common leukemia (cancer of blood cells). The purpose of this study is to assess retreatment with venetoclax-obinutuzumab (VenG) in participants previously treated with fixed duration first-line (IL) therapy of venetoclax in combination with an anti-CD20 antibody +/- X (where X is any additional drug). Adverse events and change in disease activity will be assessed. Venetoclax is an approved drug for the treatment of CLL. Study doctors put the participants in 1 of 2 groups, called cohorts, based on when symptoms of CLL came back after previous treatment in first-line. Approximately 75 adult participants with CLL who have been treated with venetoclax in combination with an anti-CD20 antibody +/- X will be enrolled in the study in approximately 60 sites worldwide. Participants will receive intravenous (IV) obinutuzumab + oral venetoclax (VenG) in 28-day cycles for a total of 6 cycles per cohort, followed by 6 to 18 cycles of venetoclax alone, for a total treatment of 12 to 24 cycles, depending on the cohort. 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.
In this study, researchers will learn more about a study drug called litifilimab (BIIB059) in participants with systemic lupus erythematosus (SLE). The study will focus on participants who have active disease and are already taking standard of care medications. These may include antimalarials, steroids, and immunosuppressants. The main objective of the study is to learn about the effect litifilimab has on lowering the activity of the disease. The main question researchers want to answer is: - How many participants have an improvement in their symptoms after 52 weeks of treatment? Researchers will answer this and other questions by measuring the symptoms of SLE over time using a variety of scoring tools. These include the SLE Responder Index (SRI), the Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K), and the Patient Global Assessment - Visual Analog Scale (PGA-VAS). Researchers will also learn more about the safety of litifilimab. They will study how participants' immune systems respond to litifilimab. Additionally, they will measure the effect litifilimab and SLE have on the quality of life of participants using a group of questionnaires. The study will be done as follows: - After screening, participants will be randomized to receive either a high or low dose of litifilimab, or placebo. A placebo looks like the study drug but contains no real medicine. - All participants will receive either litifilimab or placebo as injections under the skin once every 4 weeks. The treatment period will last 52 weeks. Participants will continue to take their standard of care medications. - Neither the researchers nor the participants will know if the participants are receiving litifilimab or placebo. - There will be a follow-up safety period that lasts up to 24 weeks. - In total, participants will have up to 22 study visits. The total study duration for participants will be up to 80 weeks.
Introduction: Heart failure with preserved systolic function encompasses several different diseases, but which have diastolic dysfunction and its components in common: myocardial stiffness and altered relaxation. Myocardial stiffness represents an important parameter for diagnosis and prognosis, but only changes in relaxation are evaluated in clinical practice. Cardiac elastography has been proposed as a diagnostic modality for noninvasive assessment of myocardial stiffness. Objective: The aim of our study is to investigate the potential of myocardial elastography by shear waves to assess myocardial stiffness by non-invasively quantifying diastolic myocardial elasticity (EMD) in Fabry disease (DF) and cardiac amyloidosis (AC ) in the ATTRh form and correlate with other complementary imaging and laboratory tests (electrocardiogram, 2D echocardiogram, troponin and BNP) and with a 6-minute walk test and quality of life questionnaires. Material and methods: 60 adults will be prospectively included: 20 patients with Fabry disease, 40 patients with hRTRT (20 with cardiac involvement) and 20 patients as a control group. Echocardiography, electrocardiogram and laboratory evaluations will be performed. The elastocardiographic assessment of myocardial stiffness will be performed in ultrasound equipment (Canon, Aplio i800) using a multifrequency convex transducer, under specific adjustment of the equipment to perform myocardial elastography.
This study aims to map the impact of anodic transcranial direct current stimulation (tDCS) for prolonged home use applied to the primary motor cortex and the left dorsolateral prefrontal córtex (DLPFC), compared to the respective treatments simulated in fibromyalgia.
Some patients develop "Post-acute COVID-19 syndrome," in which they experience persistent symptoms after recovering from the acute phase of COVID-19 infection. This syndrome may be more significant in patients with systemic autoimmune rheumatic diseases (SARDs) who have been suffering from several symptoms associated to SARDs, such as myalgia, fatigue, and general pains. The transcranial direct current stimulation (tDCS) technique has been frequent, for example, to relieve fatigue and general pains in general population. However, to date, there are no studies evaluating this technique in ARD patients with post-acute COVID-19; therefore, the main objective of the opened study is to evaluate the safety and efficacy of the application of acute tDCS in ARD patients with post-acute COVID-19.
The purpose of this Phase 3 study is to determine whether iptacopan (LNP023) is efficacious and safe for the treatment of aHUS in adult patients who are treatment naive to complement inhibitor therapy.
