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 purpose of this study is to determine whether an early Calcineurin Inhibitor (CNI) to everolimus conversion at 10-14 weeks post transplantation improves renal allograft function without compromising efficacy compared to standard CNI treatment in de novo renal allograft recipients. In addition, the study is designed to evaluate the impact of a CNI-free regimen on evolution of cardiovascular parameters in de novo renal allograft recipients
This study is designed to evaluate the safety and efficacy of a regimen containing Cobicistat (COBI)-boosted atazanavir (ATV/co) plus emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) versus ritonavir (RTV)-boosted atazanavir (ATV/r) plus FTC/TDF in HIV-1-infected, antiretroviral treatment-naive adults. Development of COBI as a "pharmacoenhancer" could provide a beneficial alternative to RTV for use in combination with protease inhibitors.
The purpose of this study is to evaluate the efficacy and safety of canagliflozin compared with sitagliptin and placebo in patients with type 2 diabetes mellitus who are receiving treatment with metformin monotherapy (i.e., treatment with a single drug) and have inadequate glycemic (blood sugar) control.
To evaluate the safety and efficacy of Stribild®, a single tablet regimen (STR) containing fixed doses of elvitegravir (EVG)/cobicistat (COBI [GS-9350])/emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) versus ritonavir-boosted atazanavir (ATV/r) plus the standard of care nucleoside reverse transcriptase inhibitor (NRTI) backbone FTC/TDF (Truvada®). ATV/r + FTC/TDF was selected as the active comparator for this study as it is a preferred protease inhibitor-based regimen in guidelines for the treatment of HIV-1 infected, antiretroviral treatment-naive adults.
This is a randomized, double-blind, placebo-controlled multi-center phase III study to evaluate efficacy and safety of regorafenib in patients with metastatic colorectal cancer (CRC) who have progressed on/after all approved drugs for CRC
Study of Plitidepsin in combination with dexamethasone versus dexamethasone alone in patients with relapsed/refractory multiple myeloma.
Rationale: Gathering medical information and tumor samples from patients with male breast cancer may help doctors learn more about the disease. Purpose retrospective part: to perform a large international retrospective analysis of clinical and biological data of male BC patients treated in the participating centers from 1990 to 2010. Purpose prospective part: to create a registry of men with breast cancer for a period of 30 months (starting early 2014).
Psoriasis is a chronic, often severe, autoimmune condition that affects approximately 2% of the world's population. The epidemiology of pediatric psoriasis has not been well documented and no treatment guidelines exist for pediatric psoriasis. Etanercept is a biologic drug and has been licensed for the treatment of chronic severe plaque psoriasis in children and adolescents (6-17 years of age) who are inadequately controlled by or are intolerant to, other systemic therapies or phototherapies. Although the long-term safety and efficacy of etanercept in children with juvenile idiopathic arthritis (JIA) has been studied and the short-term safety profile of etanercept in both JIA and pediatric psoriasis appears similar, there is limited data available about the long-term effects of etanercept in pediatric psoriasis, especially with respect to malignancy. The aim of this study is to assess the safety and effectiveness of etanercept for the treatment of pediatric psoriasis in Europe. Patients aged <=17 with plaque psoriasis diagnosed by a dermatologist will be invited to participate in the registry only after a clinical decision has been made to prescribe etanercept. The safety of the drug and how well the drug works will be evaluated during the follow-up period. The follow-up period will last 5 years and patients will be followed up every 3 months for the first 2 years and every 6 months for the next 3 years or until the end of study.
The objective of this study is to obtain a better understanding of the spectrum of use of mechanical ventilation in intensive care units: 1. Main analysis: To know the all-cause mortality rate in mechanically ventilated patients 2. Secondary analyses: - To know the current status of mechanical ventilation in the intensive care unit and determine the number and percentage of patients who are admitted to an intensive care unit and require mechanical ventilation. - To compare the results with prior data collected in previous observational studies (1998 and 2004) - Non-invasive positive pressure ventilation - Weaning - Use of adjuvant therapies as steroids or selective digestive decontamination - Sedation including prevalence of delirium in mechanically ventilated patients - Prediction of the duration of mechanical ventilation - Other
The purpose of this study is to determine whether the percentage cases which have ideal mechanical axial alignment using the Vanguard total Knee implant with the Signature cutting blocks is higher than those without the use of Signature when measured immediately post-operatively.
