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.
This is an open label, randomized, controlled, multicenter phase II study comparing 5-FU/FA + oxaliplatin (FOLFOX-4) + cetuximab versus 5-FU/FA + oxaliplatin as first-line treatment for epidermal growth factor receptor (EGFR)-expressing mCRC.
The purpose of this study is to test whether SR123781A is a possible treatment for patients with acute coronary syndromes (heart attack) who are scheduled to undergo a percutaneous coronary intervention (PCI) within 48 hours after inclusion in the study. Two doses of SR123781A are currently tested, each in a group of about 180 patients per group to find which is the most adequate, versus heparin and glycoprotein IIbIIIa (GPIIBIIIA) antagonist.
This is a clinical trial assessing the time to relapse of anxiety symptoms among patients with generalized anxiety disorder who have responded to duloxetine therapy.
The purpose of this trial is to investigate the efficacy of cetuximab in combination with chemotherapy in comparison to chemotherapy alone in patients with recurrent or metastatic head and neck cancer. Overall survival will be taken as the primary measure of efficacy.
The purpose of this study is to compare long-term safety and tolerability of stavudine (d4T) extended release (ER) versus conventional (immediate release [IR]) formulations, each in combination with lamivudine (3TC) and efavirenz (EFV) in subjects who have completed Bristol-Myers Squibb (BMS) studies AI455-096 and AI455-099.
Recent studies support the hypothesis that aortic stenosis (AS) develops due to atherosclerosis affecting the aortic valve endothelium. The study’s aim was to assess Rosuvastatin on the hemodynamic progression and inflammatory markers of AS by treating low-density lipoprotein (LDL) in patients with AS according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII) guidelines for one year.
Study TMC114-C214 is a randomized, controlled, open-label trial to compare the efficacy, safety and tolerability of TMC114 boosted with low dose ritonavir (RTV) versus Kaletra (LPV)/RTV in lopinavir-naïve treatment-experienced HIV-1 infected patients.
The purpose of this study is to determine the effect of short cycles of recombinant interleukin-2 (also known as rIL-2 or aldesleukin) given with or without anti-HIV drugs in HIV infected patients. The effects will be compared with a study group that receives no IL-2 or antiretroviral therapy. Study hypothesis: Intermittent aldesleukin, when given without antiretroviral therapy to patients with early HIV infection, will produce no change in HIV viral load and increases in CD4+ T lymphocyte counts comparable to aldesleukin administered with antiretrovirals.
The primary objective of this study is to evaluate the efficacy and safety of glucosamine sulfate versus placebo on the symptoms of knee osteoarthritis after 6 months of treatment, using acetaminophen as a reference symptomatic medication.
This 2 arm study will assess the safety and efficacy of tocilizumab monotherapy versus methotrexate in patients with active rheumatoid arthritis (RA). Patients will be randomized to receive tocilizumab 8mg/kg iv every 4 weeks plus placebo po weekly, or methotrexate 7.5-20mg po weekly plus placebo iv every 4 weeks. The anticipated time on study treatment is 3-12 months and the target sample size is 500+ individuals.
