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 purpose of this study is to evaluate the efficacy and safety of risankizumab versus placebo during induction therapy in participants with moderately to severely active Crohn's disease (CD).
This is a 2-part trial: a Phase 1, open-label, dose-escalation study in subjects with metastatic or locally advanced solid tumors, with a consecutive Phase 2 expansion to evaluate efficacy in subjects with recurrent, unresectable, or metastatic (advanced) cervical cancer that has progressed after a platinum-based treatment regimen.
Of the patients diagnosed with ST-segment elevation myocardial infarction (STEMI) who underwent reperfusion therapy and have thrombolysis in myocardial infarction (TIMI) 3 flow, about 40% have flow alterations in the coronary microcirculation, which leads to worse remodeling of the left ventricle with a consequent increase in the mortality of this population. Clopidogrel is the only known antiplatelet medication that brings benefits to the coronary microcirculation. Ticagrelor is significantly superior to clopidogrel in terms of decreasing mortality. The main objective of this study is to compare the effect of ticagrelor versus clopidogrel on the coronary microcirculation by the Myocardial Perfusion Score Index (MPSI) obtained using Microbubble Contrasted Echocardiography (MCE) in patients who have STEMI and treated with thrombolysis.
The main goal of this project is to evaluate the effect of immunosuppression in the weight loss and in the metabolic status of patients after liver transplantation. It is also the purpose of this project to investigate why patients become overweight and obese after liver transplantation.
Evaluation of the local tolerance and cosmetic efficacy of a topical skin care formulation in healthy female participants with mild to advanced photo-damaged facial skin who have undergone a 70% Glycolic Acid facial peel procedure.
Obesity and gum diseases are highly prevalent in all parts of the world. Obesity can negatively influence severity and progression rates of gum diseases. Presence of fat in the body determines a general systemic state of inflammation. On the other hand, when gum diseases are successfully treated systemic and local inflammation decrease. In addition reductions in glycemic blood levels are also observed after treatment. Periodontitis is one type of gum disease that is associated with bone loss. It could be treated within 24 hours by using a protocol, which combines dental debridement and mouthwash. This treatment protocol, named "one-stage full-mouth disinfection" works well in individuals of normal weight. However, there is no information whether it is effective in obese individuals or not. Also, it should be clarified if obesity influences response to periodontal treatment. This study hypothesized that obesity impair response to periodontal treatment. Therefore, the effects of the protocol "one-stage full-mouth disinfection" will be evaluated in obese individuals and normal weight controls. This evaluation will be based on the monitoring of several clinical, microbiological and biochemical parameters throughout 9 months. Participants will answer validated questionnaires to evaluate if treatment of gum disease would be able to improve individual's quality of life. Study population will be composed of 90 to 100 obese individuals (males or females; > 18 years of age; smokers or non smokers; > 12 natural teeth). Participants will be classified into 5 groups according to their body mass index in normal weight (n = 15 to 20); overweight (n = 15 to 20); obesity I (n = 15 to 20); obesity II (n = 15 to 20); obesity III (n = 15 to 20). Examinations will be performed before treatment and also 3, 6 and 9 months after treatment. This study will contribute to the knowledge on how obese individuals respond to this specific treatment protocol. Also, having normal weight individuals as controls the present study will contribute to a better understanding about obesity, in its different severities, influence on periodontal treatment.
The purpose of this study is to determine the benefit of relugolix 40 milligrams (mg) once a day co-administered with estradiol (E2) 1 mg and norethindrone acetate (NETA) 0.5 mg compared with placebo for 24 weeks on heavy menstrual bleeding associated with uterine fibroids.
This study will be featured as a randomized controlled. As the dependent variable, was considered isometric grip manual force. As independent variable, the presence or absence of forearm bandage in the fist flexor region of the volunteers.
This is a cohort study with the objective of describing during a 12-month follow-up, weight loss in obese patients submitted to treatment using two consecutively air-filled IGB (Heliosphere® 600 cc and Heliosphere 720 cc) without any interval between the removal of the first and the placement of the second.
Non-specific chronic low back pain is a common multifactorial condition common to the world population. It is defined as a pain and discomfort located below the ribs and above the gluteal folds that may or may not have referred pain in the leg for more than 12 weeks. Visceral manipulation is a manual therapy technique that aims to normalize mechanical, vascular and neurological dysfunctions of the viscera with the objective of improving its functioning. Visceral dysfunction may potentially activate or exacerbate the symptoms of low back pain in the presence of compromised movements between the internal organs and its connective tissues. There are two ways in which a change in visceral mobility could interfere with low back pain, referred visceral pain and central hypersensitivity. The first occurs due to neural convergence, since there is no spinocortical tract that only sends visceral or somatic afferences, its afferences are crossed in the dorsal horn of the spinal cord. The second is that the prolonged and continuous activation of nociceptors, due to the alteration in the mobility of the gastrointestinal and urinary system, can generate central hypersensitivity. Therefore, the investigators hypothesized that through the visceral manipulation the fascial adherences would lyse and the visceral spasms would demise, reducing the peripheral input, thus, lessening pain in the low back.
