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 demonstrate the safety and efficacy of the ZoMaxx drug-eluting stent in patients with blockage of native coronary arteries. The study is designed to demonstrate non-inferiority to the TAXUS Express2 Paclitaxel-Eluting Stent that has proven superior to bare metal stents and is a recognized standard of care.
To determine whether Lipitor reduces stroke, compared to placebo in patients who have had a previous stroke or transient ischemic attack.
The purpose of the study is to determine whether steroids decrease 28-day mortality in patients with septic shock.
The objective of this study is to determine the long term safety and tolerability of multiple oral doses of tipranavir (Aptivus) and ritonavir with a focus on the long term safety of the development dose (500 mg tipranavir/200 mg ritonavir BID) when administered with other antiretroviral medications.
The Mucopolysaccharidosis I (MPS I) Registry is an ongoing, observational database that tracks the outcomes of patients with MPS I. The data collected by the MPS I Registry will provide information to better characterize the natural history and progression of MPS I as well as the clinical responses of patients receiving enzyme replacement therapy, such as Aldurazyme (Recombinant Human Alpha-L-Iduronidase), or other treatment modalities. The objectives of the Registry are: - To evaluate the long-term effectiveness and safety of Aldurazyme® (laronidase) - To characterize and describe the MPS I population as a whole, including the variability, progression, and natural history of MPS I - To help the MPS I medical community with the development of recommendations for monitoring patients and reports on patient outcomes to optimize patient care
The primary objective of this trial is to determine whether daily treatment with tiotropium (Spiriva®, Bromuro de Tiotropio®) inhalation capsule via HandiHaler® reduces the rate of decline in lung function over time in patients with COPD.
The objective of this study is to demonstrate the safety and efficacy of tipranavir/ritonavir versus an active control arm in highly treatment experienced Human immunodeficiency virus-1 infected patients. Patients must have a viral load > =1000 cells/mL, and genotype indicating at least one resistance conferring protease inhibitor-mutation as determined from a predefined panel of mutations. Any CD4+ count is acceptable.
To see if Disease Free Survival (DFS) is improved when complete surgical resection of liver metastases (R0) is followed by chemotherapy with CPT-11 and 5-FU/FA as FOLFIRI regimen, compared to 5-FU/FA alone.
To prevent recurrence of invasive fungal infection in patients with allogeneic stem cell transplants
To evaluate long-term efficacy and safety of pregabalin (150 to 600mg/day) as adjunctive treatment in patients with partial seizures.
