There are about 3194 clinical studies being (or have been) conducted in Portugal. 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 European Surgical Outcomes Study (EuSOS) is a multi-centre, international cohort study of peri-operative care and clinical outcomes for patients undergoing non-cardiac surgery. Participating centres throughout Europe will contribute routine clinical data describing all eligible patients who undergo surgery from 4th April 2011 to 11th April 2011. Patients will then be followed until hospital discharge (or for a maximum of 60 days) for duration of hospital stay and hospital mortality. Routine clinical data will also be collected for those patients admitted to critical care at any stage after surgery but during the same hospital admission. Specific objectives are to describe clinical outcomes and standards of peri-operative care for patients undergoing non-cardiac surgery in Europe.
The purpose of this study was to collect long-term safety and tolerability, long-term efficacy, and health outcome data in all patients currently ongoing in the fingolimod multiple sclerosis clinical development program. This study combined all currently ongoing Phase II and III fingolimod extension studies as well as ongoing and newly planned studies into one single long-term extension protocol that provided patients with continuous treatment until fingolimod was registered, commercially available, and reimbursed in the respective countries.
The purpose of the study is to evaluate the effectiveness of two dosing regimens of fostamatinib compared to placebo, in patients with rheumatoid arthritis (RA) who are taking methotrexate and have had an inadequate response to a single TNF-alpha antagonist. The study will last for approximately six months.
The purpose of the study is to evaluate the effectiveness of two dosing regimens of fostamatinib compared to placebo, in patients with rheumatoid arthritis (RA) who are taking disease modifying anti-rheumatic drug (DMARD) but not responding. The study will last for 1 year.
This randomized, parallel group, double-blind, placebo controlled study will evaluate the efficacy and safety of ocrelizumab in participants with primary progressive multiple sclerosis. Eligible participants will be randomized 2 : 1 to receive either ocrelizumab or placebo.
This is a randomized, double-blind, multicenter, phase 3 study evaluating orteronel (TAK-700) plus prednisone compared with placebo plus prednisone in the treatment of men with progressive, chemotherapy-naive, metastatic, castration-resistant prostate cancer (mCRPC)
This study is intended to provide up to a maximum of four years of annual oncogenic human papillomavirus (HPV) DNA testing and cervical cytology examination for NCT00294047 study subjects who displayed normal cervical cytology but tested positive for oncogenic HPV infection at their concluding NCT00294047 study visit. Women who were pregnant at their concluding NCT00294047 study visit may also be included in this study, as no cervical sample could be collected at that visit. The objectives and outcome measures of the primary phase (NCT00294047) are presented in a separate protocol posting.
RATIONALE: Collecting and storing samples of tumor tissue, blood, bone marrow, and other body fluids from patients to test in the laboratory and collecting information about the patient's health and treatment may help doctors learn more about cancer and help the study of cancer in the future. Studying these samples in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is collecting and looking at blood and tissue samples in children with newly diagnosed acute lymphoblastic leukemia.
The purpose of this study is to observe the performance of Therapy™ Cool Flex™ catheter by documenting the procedural parameters, major complications and recurrence of AF after ablation using Cool Flex ablation catheter for the treatment of paroxysmal atrial fibrillation. This study is an observational clinical study which is not based on any specific endpoints.
The purpose of this study is to compare overall survival in participants with metastatic colorectal cancer treated with either ramucirumab and FOLFIRI or placebo and FOLFIRI.
