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.
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.
The Fabry Registry is an ongoing, international multi-center, strictly observational program that tracks the routine clinical outcomes for patients with Fabry disease, irrespective of treatment status. No experimental intervention is involved; patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician. The primary objectives of the Registry are: - To enhance the understanding of the variability, progression, and natural history of Fabry disease, including heterozygous females with the disease; - To assist the Fabry medical community with the development of recommendations for monitoring patients and reports on patient outcomes to help optimize patient care; - To characterize and describe the Fabry population as a whole; - To evaluate the long-term safety and effectiveness of Fabrazyme® Fabry Pregnancy Sub-registry: This Sub-registry is a multicenter, international, longitudinal, observational, and voluntary program designed to track pregnancy outcomes for any pregnant woman enrolled in the Fabry Registry, regardless of whether she is receiving disease-specific therapy (such as enzyme replacement therapy with agalsidase beta) and irrespective of the commercial product with which she may be treated. Data from the Sub-registry are also used to fulfill various global regulatory requirements, to support product development/reimbursement, and for other research and non-research-related purposes. No experimental intervention is given; thus a patient will undergo clinical assessments and receive standard of care treatment as determined by the patient's physician. If a patient consents to this Sub-registry, information about the patient's medical and obstetric history, pregnancy, and birth will be collected, and, if a patient consents to data collection for her infant, data on infant growth through month 36 postpartum will be collected.
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.
This trial is conducted in Europe. Objective(s): To evaluate the effect of human growth hormone on infants aged 1 to 2 years with chronic renal insufficiency (CRI) and growth retardation despite an adequate dietary intake. Trial Design: This is an open, parallel group clinical trial with a duration of one year, in which period 50% of patients will receive GH treatment and the other 50% will act as a control group, without treatment. Trial Population: The trial will involve a total of 16 infants aged from 12±3 to 24 months suffering chronic renal insufficiency (Glomerular Filtration Rate less than 60 ml/min/1.73 m2), and growth failure and undergoing conservative treatment or peritoneal dialysis. Include the key inclusion and exclusion criteria.
This trial is conducted in Europe and Middle East. Growth hormone in SGA Children This trial compares a treated group of patients with an untreated group of patients.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether radiation therapy is more effective than temozolomide in treating gliomas. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared to temozolomide in treating patients with gliomas.
