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 main goal of this study is to improve the outcome of children and adolescents with standard risk (SR) first relapsed acute lymphoblastic leukemia. Furthermore, goal is to set up a large international study group platform allowing for optimization of standard treatment strategies and integration of new agents.
The primary objective of this study is to evaluate the efficacy of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) versus elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) in HIV-1 positive, antiretroviral treatment-naive adults.
Primary objective of the study is to compare the efficacy of romidepsin when administered with CHOP versus CHOP alone in subjects with previously untreated peripheral T-cell lymphoma (PTCL) in terms of progression-free survival (PFS) assessed according to Response criteria for malignant lymphoma 1999 by a Response Adjudication Committee (RAC).
This study assesses clinical and imaging long-term data, after early or delayed interferon-beta-1b treatment in patients with a first demyelinating event suggestive of multiple sclerosis (MS), 11 years after enrollment in the Betaferon/Betaseron in Newly Emerging Multiple Sclerosis for Initial Treatment (BENEFIT) study (304747). The main objectives are to describe the disease course, change in disability, cognitive function, resource use and employment status, in relation to Interferon beta-1b in the long term.
The purpose of this study is to allow continued use of pasireotide in patients who are on pasireotide treatment in a Novartis-sponsored study and are benefiting from the treatment as judged by the investigator.
Justification and background Ventilator-associated complications (VACs) are those complications that develop during a period of intubation of a patient . Pneumonia is the second most frequent infectious complication in the hospital, and ranks first in ICU, whose risk is increased more than 20 times by the presence of invasive mechanical ventilation and is called ventilator-associated pneumonia (VAP) . Whereas the information published regarding VAP in terms of diagnosis, treatment and impact on the outcome of critically ill patients is enormous.Ventilator-associated tracheobronchitis (VAT) incidence is lacking and complicated in part, since the definition remains controversial. In addition, the significance of tracheobronchial colonization as a risk factor for subsequent lower respiratory tract infection remains unclear . The upper and lower airways can become colonized . Several factors have been taken into account and do not differ from those involved in VAT and VAP development in patients under mechanical ventilation. Definition VAT diagnosis is controversial and represents an actual problem in order to define the real incidence of VAT , There is currently no valid, reliable definition for VAT, and even the most widely-used VAT criteria and definitions are neither sensitive nor specific. The diagnosis of VAT is considered when a patient under invasive mechanical ventilation starts with fever, leukocytosis and new or increased purulent secretions by the endotracheal tube. A particular difficulty with much commonly used VAT definition (in order to distinguish from VAP) is the key point of the absence of pulmonary consolidation. Evidence suggests that chest radiograph findings do not accurately role out VAP. A taskforce on hospital-acquired pneumonia, and VAP has been recently published (European Respiratory Society (ERS), European Society of Clinical Microbiology and Infectious Diseases (ESCMID) and European Society of Intensive Care Medicine (ESICM)). Nosocomial tracheobronchitis definition includes occurrence of purulent tracheal secretion after ≥48 h of hospitalisation or mechanical ventilation plus ≥2 of the following: fever (≥38.5°C) or hypothermia (<36°C), leukocytosis (≥12 × 109/L), significant bacteriologic counts in respiratory secretions (≥103 cfu/mL for protected brush specimen (PBS) and ≥105 cfu/mL for endotracheal aspirates); absence of new pulmonary infiltrates compatible with pneumonia and absence of other causes of fever are mandatory. This definition needs to be further validated and can overdiagnose the incidence of VAT (and overuse of antibiotics) because the positive culture of respiratory secretions is not a mandatory item RATIONALE Given the possible high incidence of VAT, and its importance as a risk factor for VAP, and a potential target to treat in order to reduce VAP incidence, a large multicentre
This multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of tocilizumab in participants with GCA. The study will consist of 2 parts: a 52-week double-blind treatment period (Part 1) followed by a 104-week open label long-term follow-up period (Part 2). In Part 1 of the study eligible participants will be randomized to receive either tocilizumab every week (qw) or every 2 weeks (q2w) or placebo for 52 weeks, with tapering oral daily doses of prednisone. After Week 52, participants in remission will stop study treatment and enter long-term follow-up, whereas participants with disease activity or flares will receive open-label tocilizumab or other treatment at the discretion of the investigator for a maximum period of 104 weeks.
The aim of the study is to assess safety, tolerability and clinical effects of different doses of riociguat in patients with inoperable Chronic Thromboembolic Pulmonary Hypertension (CTEPH) and who are not satisfactorily treated and cannot participate in any other CTEPH trial. In the US the study runs as an Expanded Access program under 21 CFR 312.320.
This study will assess the efficacy, safety and tolerability of QVA149 in patients with moderate to very severe COPD.
This study will evaluate and compare two individualized ranibizumab treatment regimens in patients with neovascular (wet) AMD aiming to achieve and to maintain a maximum visual function benefit, while aiming to avoid unnecessary intravitreal injections. The results will be used to generate further recommendations on functional and anatomical monitoring of the disease and timing of treatment administration for patients with neovascular AMD. In this context, the study will investigate the utility of optical coherence tomography (OCT) to aid retreatment decisions with ranibizumab.
