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 objectives of this program are: to further characterize the natural progression of MPS VI disease; to generate and disseminate information on the care and management of MPS VI patients to clinical and medical professionals; to provide a resource to physicians and patients by providing information for optimizing patient care based on aggregate data; to characterize the clinical response to long-term Naglazyme® (galsulfase) treatment; to further characterize the long-term safety of Naglazyme® treatment.
The purpose of this study is to compare the proportion of subjects with HIV-1 RNA viral load < 50 c/mL through Week 48 of the Maintenance Phase among HIV-infected subjects with an initial undetectable viral load following an Induction Phase with an ATV/RTV containing HAART regimen, when switched to ATV versus remaining on ATV/RTV, whilst continuing their previous NRTI backbone.
The purpose of the study is to investigate if rosuvastatin, added on top of all other medicines prescribed to subjects with symptomatic systolic heart failure, reduces the combined endpoint of cardiovascular death or non-fatal myocardial infarction or non-fatal stroke (time to first event)
Essential thrombocythaemia is a disorder of bone marrow, which causes too many platelets to be produced. Platelets are small cells carried around in the blood, which help form blood clots. When patients have too many platelets, there is a risk of blood clots forming unnecessarily and excessive bleeding. The aim of this study is to gain additional information on the safety profile of Anagrelide (Xagrid(r)) and Hydroxyurea (also known as hydroxycarbamide).
Approximately 520 patients will be entered into this study taking place throughout Australia and Europe. This study aims to determine if an investigational drug is safe and effective for treating symptoms of C. difficile-associated diarrhea (CDAD) and lowering the risk of repeat episodes of CDAD. The investigational drug will be evaluated in comparison to current standard antibiotic treatment, so all patients will receive active medication. All study related care is provided including doctor visits, physical exams, laboratory tests, and study medication. The total length of participation is approximately 6 weeks.
This study will provide a direct comparison of 'continuous therapy' and 'intermittent therapy' with withdrawal and retreatment upon return of psoriasis.
The aim of the study is to test [90]Y-ibritumomab tiuxetan, a radioactive antibody, in patients with stage III or IV follicular lymphoma whose disease is in partial or complete remission after first line chemotherapy. The radioactive antibody will be compared with no further treatment to see which is better in the long term after standard lymphoma treatment.
The aim of this study is to monitor long-term safety and tolerability of iloprost aerosol inhalation therapy in patients suffering from pulmonary hypertension.
This study will primarily compare the long-term effects of an early and continued treatment with Betaferon/Betaseron (patients who were treated with active medication during the double-blind BENEFIT study) to treatment initiated either after Clinically Definite Multiple Sclerosis (CDMS) has been diagnosed or after two years (those patients who were treated with placebo during the double-blind BENEFIT study). Analyses are based on the integrated data of the initial BENEFIT study and this follow-up study.
To test the efficacy and safety of olmesartan in patients with essential hypertension.
