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 study consists of two parts. Part 1 determines the safety and tolerability of BGB-11417 (sonrotoclax) monotherapy, the maximum tolerated dose, and the recommended Phase 2 dose of BGB-11417 monotherapy for relapsed or refractory mantle cell lymphoma. Part 2 evaluates efficacy of BGB-11417 monotherapy at the recommended Phase 2 dose with recommended ramp-up schedule from Part 1.
Incontinence-associated dermatitis (IAD) is an inflammation of the skin that occurs as a result of urine or feces contact on the perineal or perigenital region in adults. Lesions are typically located in the convex regions covered by diapers. The perineal region is the most affected, bringing pain and discomfort to the participant. The prevention and treatment of IAD must essentially follow two interventions: the control of incontinence/dampness and the implementation of a structured regimen of perineal care, seeking results for the restoration of skin integrity. Therefore, the gold standard for the treatment of IAD is skin hygiene, moisture control, and the use of a skin protector to restore skin integrity. Photobiomodulation has been used with excellent results in restoring skin integrity in acute and chronic wounds, but so far it has not been tested for IAD. To evaluate the effect of photobiomodulation in the treatment of incontinence-associated dermatitis in adults. A total of 78 with participant who developed lesions that present erythema with intact skin and erythema with loss of continuity, resulting from IAD, will be included in the study. Participants will be randomly divided into 2 groups: Control group use of liquid protective film in spray + FBM simulation (placebo), Experimental group (n=39) - use of liquid protective film in spray + FBM. FBM will be performed with a 660 nm 100mW diode laser, 2 J per point, in 8 points and radiant exposure of 707 J/cm2. FBM will be applied once a day every 24 hours for 3 days in a row. Both groups will continue with standard daily skin care and diaper changes every 3 hours. The primary endpoint was chosen for the 7-day IAD lesion cure rate study. A photographic record of the lesion area and measurements will be performed using a disposable ruler with the participant in a lithotomous position on the days of the evaluations. For the classification and characterization of the severity of IAD, the Ghent Global IAD Categorization tool will be applied. In addition, the size of the area will be analyzed using ImageJ software program. For pain assessment, the visual analog scale will be used in conscious participants and the BPS scale in participants with cognitive impairment and who are intubated. All outcomes will be evaluated at baseline, at 24 hours, 3 days, and 7 days.
This is an exploratory phase 3, cohort randomized, observer-blind, multi-center study to evaluate the safety and immunogenicity of a 4th dose of various SARS-CoV-2 vaccines. There will be 04 study cohorts, that have previously received 03 doses of the indicated vaccine (s), divided into 10 groups; and each one of the 10 study groups will receive the 4th dose. This exploratory study will enroll up to 360 participants in 4 cohorts and a total of 10 groups: Cohort A (N=90), Cohort B (N= 90), Cohort C (N=150) and Cohort D (N=30). In cohorts A-C participants will be randomized 1:1:1 to three different 4th dose regimens. The number of proposed participants will provide a reasonable accurate descriptive summary of the safety and immunogenicity of the tested vaccination regimens.
Postoperative bone infection is a severe complication in the treatment of fractures and is more frequent than in elective joint replacement surgeries. Surgical treatment is based on meticulous debridement of bone and soft tissue, dead space management, soft tissue reconstruction when necessary, and restoration of bony stability in the non-union fracture. In addition, local antibiotic therapy is recommended in certain circumstances. This study aims to evaluate the results of surgical treatment of fracture-related infection in Latin America.
The Phase 2 study will be conducted in adult patients with confirmed Dengue infection and will investigate safety, PK, and pharmacodynamics (PD) in this population. The study will be conducted in several dosing cohorts to enable dose selection for subsequent trials
Introduction: Due to the COVID-19 pandemic scenario, social distancing has become the main strategy to contain this pandemic, causing negative impacts on the physical and mental health of the elderly population. To promote the continuity of offering health services during isolation telerehabilitation was used. Thus, it is important to investigate the effect of a physical exercise program and health education through telerehabilitation on physical and mental aspects in order to establish it as an alternative care for the elderly. Objectives: To evaluate the effect of a program of physical exercises and health education by telerehabilitation on signs of sarcopenia, physical performance, hand grip strength and levels of anxiety, depression and sleep quality in elderly women. Method: In this non-randomized clinical trial, considered a pilot study, eight elderly women (73,00±4,69 years old) will be submitted to 16 weeks of intervention through a program of physical exercise and health education using the Google Meet platform (synchronous online), frequency of 3 weekly sessions and duration of 50' (Initial rest: 5'; Warm-up: 15': Resistance exercises: 20'; Stretching exercises: 5'; Relaxation and final rest: 5'). Before and after the intervention period, the following tests will be applied: SARC-F, Short Physical Performance Battery, hand-grip dynamometry, Geriatric Anxiety Inventory, Geriatric Depression Scale and Pittsburgh Sleep Quality Index. To compare the two moments, the paired Student's T-test or Wilcoxon test (normality assessed by the Shapiro-Wilk test) will be used with p<0.05.
Systemic arterial hypertension is a serious health problem worldwide. In some cases, it can phenotypically present as resistant arterial hypertension, which consists of blood pressure levels outside the treatment goals in patients using three or more classes of antihypertensive drugs, one of which is preferably a thiazide diuretic. Resistant hypertension contributes to a 47% higher risk of developing cardiovascular events when compared to patients with non-resistant hypertension. It is known that the microcirculation plays a relevant role in the pathophysiology of arterial hypertension. Furthermore, it is known that the cutaneous microvascular network is an adequate model and that it reflects the systemic microcirculation. In this sense, the present research proposes the study of cutaneous capillary density - through high resolution intravital microscopy - and of the endothelium-dependent and independent microvascular vasodilator response - by the speckle laser flowmetry method coupled to a pharmacological system of micro- iontophoresis - in patients diagnosed with resistant hypertension, with the aim of identifying changes in comparison with patients with non-resistant hypertension and normotensive individuals. Additionally, the evaluation of the association between systemic microvascular function and the presence of target organ lesions in this population may indicate that this is a new non-invasive way of stratifying cardiovascular risk in these individuals.
Pelvic chemoradiotherapy (CRT) is an effective treatment for Locally Advanced Cervical Cancer (LACC). However, CRT induces premature ovarian failure ceasing the production of ovarian hormones. This may lead to severe consequences to the patient's life quality, sexuality and overall healthy. An acceptable treatment to minimize the adverse effects caused by the lack of ovarian hormones is hormonal replacement but less than 40% of the patients younger than 50 years have access to this treatment. A second alternative treatment is ovarian transposing which is a surgical technique with variable success rate depending on how far the ovaries are from the radiotherapy field. A third, more promising, alternative is involves using autologous ovarian tissue as a graft in tissues far from the radiotherapy field. This treatment has the potential of maintaining the natural ovarian hormones production at a lower-cost and requiring a simpler procedure. The primary objective of this randomized phase 1-2 clinical trial is to validate the feasibility of ovarian tissue engraft into fatty tissue and its endocrine functionality.
Practising physical activity after a stroke is essential for the secondary prevention of stroke. However, the major individuals after stroke are sedentary. Individuals after stroke with mild disabilities could have fewer barriers to this practice. Thus, finding ways to promote physical activity after stroke in these individuals is important for them and public health. Interventions that consider behaviour change strategies are a good way to change a habit and could improve physical activity levels. Self-management interventions have been used to promote behaviour change in the stroke population. The aim of this pilot trial will be to determine the efficacy of a self-management program to increase physical activity levels in stroke survivors with mild disability through 6 home-based sessions of self-management exercise over 3 and 6 months in a low-income country. Our secondary aims are to evaluate the effect of a self-management program on walking, exercise self-efficacy, participation, quality of life, depression and cardiovascular risks after 3 and 6 months.
Introduction: Currently, clinical practice guidelines recommend exercise as a first-line approach to the treatment of chronic low back pain (LBP). On the other hand, passive techniques such as cupping therapy have gained space in the management of this population, however, important gaps regarding the combination of cupping therapy with active exercises in individuals with nonspecific chronic low back pain are still present in the literature. In this context, this protocol describes a sham-controlled, randomized and blinded study that aims to evaluate the additional effects of cupping therapy in association with McKenzie method exercises on pain and functional outcomes of individuals with nonspecific chronic low back pain. Methods: 108 individuals with nonspecific and localized chronic low back pain in the age group of 18 to 59 years will be recruited and evaluated, regarding the inclusion and exclusion criteria. Subsequently, they will be randomized to one of 2 groups: intervention group, in which they will be submitted to the McKenzie method intervention and later the addition of the dry suction cup; and sham group, in which, after the intervention of the McKenzie method, the application of the sham cup will be added.
