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.
Patients with single brain metastasis without other metastatic site have a better prognosis, and they need a better brain metastasis control. For non-resectable and non-radiosurgical brain metastasis, the gold standard treatment is whole-brain irradiation with 30 Gy in 10 fractions, but the local control is not achieved in most of the cases. This study investigate the possibility to increase radiation dose in this metastasis with exclusive hypofractionated stereotactic radiotherapy.
The purpose of the study is to compare the survival of participants who receive chemotherapy and ramucirumab versus chemotherapy alone as second line treatment for NSCLC after prior first line platinum-based chemotherapy.
This observational long-term follow-up study will assess the persistence of direct acting antiviral (DAA) resistant mutations and the durability of sustained virological response in patients with chronic hepatitis C who have participated in a Roche DAA treatment protocol. Up to 5 scheduled monitoring visits for blood sampling during an observational period of up to 36 months.
This is an international, randomized, double-blind, placebo-controlled trial to evaluate the clinical efficacy of palifosfamide-tris administered with doxorubicin in combination, compared with doxorubicin administered with placebo in front-line patients diagnosed with metastatic soft tissue sarcoma (STS).
Study to evaluate the efficacy of intravenous iron supplementation in the prevention of anemia in patients receiving (neo)adjuvant breast cancer regimens.
The association of nutritional supplement TK3 to conventional treatment of cancer patients reduces the intensity and frequency of toxic effects and side effects caused by adjuvant or palliative treatments for the protection of healthy tissues, resulting in a better quality of life.
The objective of this study is to verify if there is a neurophysiologic reserve when caffeine and placebo perceived as caffeine are manipulated in closed- and opened-loop exercises. Parameters of excitability level of skeletal muscle and Central Nervous System (CNS), and peripheral metabolism will be measured
The primary objective will be to compare the Eurofarma and Alenia formulations regarding their impact on the pulmonary function of mild to moderate persistent asthma patients and the secondary objective will be to compare the three study formulations regarding the clinical control of the symptoms and the patients' compliance to the treatment.
Objective: To compare the clinical effectiveness and hospital costs, the initial empirical treatment, Oxacillin / Ceftriaxone and Amoxicillin / Clavulanate in children with Community Acquired Pneumonia (CAP) severe. Methods: Clinical prospective randomized study in children aged two months to five years of age with a diagnosis of severe CAP, according to criteria of World Health Organization (WHO), admitted to the Pediatrics Ward of the Hospital of the Medical School of Botucatu- UNESP. We excluded children with comorbid disorders (primary and secondary immunodeficiency) with acute or chronic kidney disease, referred patients receiving antibiotics proposal and history of allergy to antibiotics proposed. We included 104 children who were randomized into two groups to receive: Oxacillin / Ceftriaxone IV (GCO, n = 48) and Amoxicillin / Clavulanate IV (GAA, n = 56). Patients of the GAA, after clinical improvement, has been receiving the same oral antibiotic, and maintaining clinical stability, were discharged from hospital, the GOC received any IV treatment. The outcomes analyzed were time to clinical improvement (fever and tachypnea), duration of oxygen therapy, hospitalization time, need to expand the antimicrobial spectrum progression to pleural effusion / empyema (DP / E) and hospital costs. Treatment failure was determined by the need to expand the antimicrobial spectrum after 48 hours of hospitalization.
This trial is conducted in Europe, and North and South America. The aim of this clinical trial is to investigate if the two treatments are equally effective.
