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.
This is a Phase III, global, randomized, open-label, multicenter, study evaluating the efficacy and safety of adjuvant giredestrant compared with endocrine therapy of physician's choice in participants with medium- and high-risk Stage I-III histologically confirmed estrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-negative early breast cancer. In addition, an open-label exploratory substudy will explore the safety and efficacy of giredestrant in combination with abemaciclib in a subset of the primary study population.
EVITA is a multicentric Latin-American prospective cohort on chronic hypersensitivity pneumonitis. EVITA's objective is to identify phenotypes and/or endotypes associated with different disease trajectories measured primarily by forced vital capacity (FVC) during a 24 month follow-up period. Other secondary measures of disease progression will also be investigated such as imaging, time to death or lung transplantation, and patient-reported outcomes
The physiological/biomechanical characteristics related to muscle and tendon architecture and their possible relationship with the loss of muscle strength and fatigue in patients who were infected with COVID-19 are totally unknown. The aim of this study is to evaluate inflammatory markers, the isometric maximum voluntary force of the knee extensor torque, muscle fatigue, neuromuscular adaptations, muscle architecture, tendinous properties of quadriceps components, oxygen extraction, and body composition in participants after diagnosis with Covid-19 who had moderate and severe levels of involvement compared to a healthy control group.
A global phase 3, multicenter, randomized, trial, to Determine the Efficacy and Safety of Durvalumab in combination with Tremelimumab and Enfortumab Vedotin or Durvalumab in combination with Enfortumab vedotin for Perioperative Treatment in Patients Ineligible for Cisplatin or who refuse Cisplantin Undergoing Radical Cystectomy for Muscle Invasive Bladder Cancer. The goal of the study is to explore the triplet combination of Durvalumab, Tremelimumab and Enfortumab Vedotin in terms of efficacy and safety compared to the current Standard Of Care (SOC). Volga trial consists of two parts: Safety Run-In and Main Study. In total the study aims to enroll approximately 830 patients, who will receive triplet combination, duplet combination of Durvalumab and Enfortumab vedotin or currently approved SOC in the main trial. In the main part of the trial there is two out of three chances of being on a treatment arm and the treatment is assigned at random by a computer system. In this trial patients in the two treatment arms will receive either 3 cycles of neoadjuvant Durvalumab + Tremelimumab + Enfortumab Vedotin or Durvalumab + Enfortumab vedotin and after surgery both treatment arms will continue with adjuvant Durvalumab.
This study aims to evaluate the efficacy and safety of crovalimab in pediatric participants with aHUS.
Ongoing prospective cohort of type 2 diabetes individuals.
The microcirculation represents the primary site of exchange of oxygen and nutrients for tissues, and the preservation of microcirculatory perfusion is essential for the maintenance of organ function. The microcirculation is extremely dynamic and may vary according to the individual's temperature, systemic blood pressure, the use of medications, during physical and mental activity, age and pathological processes. In this context, the development of portable microscopes for clinical use has made possible the non-invasive visualization of the microcirculation and tissue perfusion in patients undergoing several highly complex procedures in cardiology, including cardiac surgery with cardiopulmonary bypass, ECMO (Extracorporeal Membrane Oxygenation) and in critically ill patients in intensive care. CytoCam, for example, is a handheld device that incorporates a darkfield incident light illumination system with a series of high-resolution lenses that project images to a computer dedicated to the system. Dexmedetomidine is a selective agonist of 2-adrenergic receptors in the central nervous system, whose administration results in a reduction in the activity of the sympathetic nervous system and a reduction in the systemic release of catecholamines. Its use in the perioperative period has several beneficial effects, such as reducing neuroendocrine and hemodynamic responses due to anesthesia and surgery, through induction of sedation and analgesia, in addition to reducing the consumption of opioids and anesthetics in general. Several recent studies report that the use of dexmedetomidine in the perioperative period reduces the incidence of postoperative complications, reduces the time on mechanical ventilation and attenuates the neuroendocrine response due to surgical trauma and extracorporeal circulation in patients undergoing cardiac surgery. However, the effects of dexmedetomidine on systemic microcirculation function during its use in anesthesia for elective surgical procedures of medium complexity are not yet known. In conclusion, the hypothesis of the present study is that continuous intravenous infusion of dexmedetomidine during balanced general anesthesia increases the microvascular perfusion flow rate in the sublingual mucosa, representing an increase in systemic microvascular perfusion.
One of the most important neurological consequences following Traumatic Brain Injury (TBI) is the development of post traumatic epilepsy (PTE). Nevertheless, there is still no effective therapeutic intervention to reduce the occurrence of PTE. In previous studies with animals models of epilepsy, the biperiden decreased the incidence and intensity of spontaneous epileptic seizures besides delaying their appearance. The aim of this study is the evaluation of biperiden as antiepileptogenic drug to prevent PTE and also the determination of side effects, evaluating its cost-effectiveness in patients with moderate and severe TBI.
This study aims to evaluate the viability of the combined use of wearable and portable technologies for sleep staging. The results will be compared with polysomnography, in order to achieve clinical and diagnostic validation. Three domains of devices will be used: Movement sensors, wearable EEG band and smartphones The project will be composed of two stages: In the first stage, the use of the combination of actigraphy and EEG will be used for sleep staging in a sample of 12 healthy volunteers from 20 to 40 years old, both genders and with no sleep disorders for each combination of ACT+EEG. Considering there will two of each (thus four combinations), the final sample will be composed of 48 individuals. Once recruited, evaluated according to the inclusion and exclusion criteria and consented with the terms of this study, the participants will be referred to the sleep lab, in which they will undergo a full night type-1 in lab polysomnography, following the setup recommended by the American Academy of Sleep Medicine. Concomitantly with the polysomnography, the participants will also use the combination of ACT+EEG. In the second stage, the most successful combination tested in the first stage will be tested in a clinical sample, composed by 60 participants from both genders, from 20 to 60 years old and with at least one sleep disorder or complaint. Among these, at least 30% of the sample should have moderate to severe insomnia, 30% should have high risk to sleep apnea and 70% should have excessive sleepiness scale. All the procedures, including the polysomnography will be performed identically to the first step.
Objective: To verify the effectiveness of education in pain added to other treatment modalities (manual therapy and exercises) in the outcomes of pain, functionality, depression, anxiety, stress, kinesiophobia, self-efficacy and strength.
