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.
Low back pain (LBP) is a highly prevalent condition worldwide and the leading cause of years lived with disability. In most cases, the specific pathological cause remains unidentified; therefore, the term non-specific low back pain is commonly used for such cases. Many non-pharmacological therapies are available for the treatment of low back pain aiming to reduce pain and disability. Among these options, photobiomodulation therapy (PBMT) it seems to be an interesting alternative. PBMT is a non-thermal and non-invasive clinical treatment, which has shown effects in decreased pain, modulation of inflammatory process, and tissue repair in musculoskeletal disorders. Therefore, the aim of this project is to evaluate the effects of the PBMT against placebo on pain intensity in patients with chronic non-specific low back pain.
This is a multicenter, randomized, double-blind, placebo-controlled study of niraparib plus pembrolizumab versus placebo plus pembrolizumab as maintenance therapy in participants with advanced or metastatic non-small cell lung cancer (NSCLC) who have achieved stable disease (SD), partial response (PR), or complete response (CR) following completion of standard of care first-line platinum-based induction chemotherapy with pembrolizumab. The primary hypotheses are: participants with confirmed diagnosis of NSCLC could benefit from niraparib plus pembrolizumab versus placebo plus pembrolizumab with respect to Progression-free survival (PFS) and Overall survival (OS).
This study will follow participants who are screened and confirmed with a genetic diagnosis of Limb-girdle muscular dystrophy type 2E (LGMD2E/R4), Limb-girdle muscular dystrophy type 2D (LGMD2D/R3), Limb-girdle muscular dystrophy type 2C (LGMD2C/R5), or Limb-girdle muscular dystrophy type 2A (LGMD2A/R1). These enrolled participants will be followed to evaluate mobility and pulmonary function for up to 3 years after enrollment. Additional participant data will be collected from the time the individual began experiencing LGMD symptoms to the present.
To demonstrate the functional results of patients with ankle fractures operated with arthroscopic deltoid repair.
This study aims to discover whether acquiring basic-literacy in adulthood can improve episodic memory and brain structural and functional connectivity. In a collaborative project between Brazil and USA, the investigators will use a randomized controlled trial approach to leverage the level of evidence of the benefits of basic adult-education as a possible cognitive reserve builder. If successful, the study's findings will be important in shaping policies targeting increasing access to late-life education to reduce dementia risk.
The COVA clinical study is a global multicentric, double-blind, placebo-controlled, group sequential and adaptive 2 parts phase 2-3 study targeting in patients with SARS-CoV-2 pneumonia. Part 1 is a Phase 2 exploratory Proof of Concept (PoC) study to provide preliminary data on the activity, safety and tolerability of BIO101 in the target population. Part 2 is a phase 3 pivotal randomized study to provide further evidence of safety and efficacy of BIO101 after 28 days of double-blind dosing. BIO101 is the investigational new drug that activates the Mas receptor (MasR) through the protective arm of the Renin Angiotensin System (RAS).
INTRODUCTION: Seroma is the most common complication after surgical treatment for breast cancer. It is the abnormal accumulation of serous fluid that develops under skin flaps and may be associated with necrosis, dehiscence, sepsis, and shoulder dysfunction. The therapeutic bandage has been inserted in clinical practice because it is similar to the elasticity of the skin and is able to help the circulatory and lymphatic system, reduce pain and local swelling, and may have benefits for prevention and treatment of seroma when applied compressively. . OBJECTIVE: To evaluate the effectiveness of compressive bandage in preventing seroma. METHODOLOGY: Randomized study of women over 18 years who underwent mastectomy at HCIII / INCA. Eligible patients will be allocated to the intervention and control groups by lot (270 envelopes, 135 patients per group). The intervention group, in addition to the use of the drain, will be submitted to the compression bandage on the day of hospital discharge and will be reevaluated on the seventh day. The control group will follow the institutional routine, using only the drain. The incidence and volume of the seroma, as well as the length of stay of the drain will be evaluated after 30 days through the medical record. Symptoms and skin changes resulting from the use of the bandage will be evaluated through a specific form. ANALYSIS: Descriptive analysis will be by measures of central tendency, dispersion and frequency distribution. Outcome assessment will be performed by odds ratio (for categorical variables) and by mean difference (Student's t-test), considering a 95% confidence interval. To control the confounding variables, multiple logistic regression (categorical outcome) and multiple linear regression (continuous outcome) will be performed by the Stepwise Forward method, including variables with p <0.20.
This study is being conducted to better understand the natural course of GM1 gangliosidosis, GM2 gangliosidoses and Gaucher disease Type 2 (GD2). Information is planned to be gathered on at least 180 patients with GM1 gangliosidosis, GM2 gangliosidoses, and Gaucher Disease type 2. Retrospective data collection is planned for at least 150 deceased patients (Group A). Group B is for patients alive at the time of enrollment. In Group B it is planned to prospectively collect more comprehensive data from at least 30 patients. The purpose of this study is to collect relevant information for a adequate design of a potential subsequent research program in these diseases. In this study no therapy is being offered.
The purpose of this study was to access the possible beneficial effects of oral use of pilocarpine in relieving signs and symptoms of patients with Sjogren's syndrome
Stroke is the leading cause of disability in developed countries, and the major cause of mortality in Brazil.It is associated with low quality of life, disability, decreased muscle strength and control due to the hypertonia, spasticity. These pathways can develop inadequate upper and lower limbs functional mechanisms. These changes are linked with disabilities and painful syndromes. The shoulder pain relationed after stroke has a variable prevalence from 16 to 84%, from mild to severe pain and is relationed as a precursor factor of secondary deformities, depression, longer hospital stay. Its etiology remains controversial with many possibilities as rotator cuff injuries, glenohumeral dislocation, impact syndrome, bicipital tendinitis, hand shoulder syndrome, myofascial painful syndrome, presence of spasticity and contractures, adhesive capsulitis, central pain and others. Its management is controversial and could be done with physical therapy (kinesiotherapy) intra-articular or local injections (muscles and nerves), functional electrical stimulation, acupuncture, herbal medicine, tapping, myofascial painful syndrome treatment, painkillers, anti-inflammatories and antispastic drugs like botulinum toxin A - tested in few studies, case series, against corticosteroids. The aim of this study will be to evaluate the effectiveness of the use of 200 units of abobotulinumtoxin against placebo in both pectoralis major and subscapularis: for reducing shoulder pain (Visual Analogue Scale, McGill pain scale), active and passive range of motion(goniometer),upper limb function (Fugl-Meyer test), burden of care questionnaire (apply to caregivers). This study is designed as a prospective, double-blind, randomized, controlled study in two Rehabilitation Centers (Rehabilitation Center from Santa Casa de São Paulo and Hospital de Clínicas of Universidade de Sao Paulo - Ribeirão Preto).
