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 initial placebo-controlled study followed by open treatment evaluating the effectiveness and tolerability of ropinirole long-term in patients with moderate to severe Restless Legs Syndrome.
The general aim of this study is to determine the comparative safety and efficacy of dabigatran etexilate administered orally and warfarin (International Normalized Ratio (INR) of 2.0-3.0) for the long-term treatment and secondary prevention of symptomatic venous thromboembolism in patients who have been successfully treated with standard doses of an approved anticoagulant for three to twelve months for confirmed acute symptomatic Venous Thrombo-embolism.
The purpose of this study is to determine the benefits of treating subjects with neovascular age-related macular degeneration (AMD) at an earlier stage of choroidal neovascularization (CNV) as compared to those with established CNV. Additionally, the study would like to determine the efficacy of Macugen in preserving visual function in those subjects having CNV secondary to neovascular AMD.
This study evaluated outcomes in participants with advanced ovarian epithelial adenocarcinoma receiving aflibercept. The primary objective was to compare the objective response rate of Aflibercept (ziv-aflibercept, AVE0005, VEGF trap, ZALTRAP®) 4.0 mg/kg and 2.0 mg/kg, administered intravenously (IV) every 2 weeks with historical control in participants with advanced ovarian epithelial (including fallopian tube and primary peritoneal) adenocarcinoma resistant to platinum and topotecan and/or liposomal doxorubicin. The secondary objectives was to further assess efficacy, safety, pharmacokinetics, potential biological and pharmacogenomic markers of study drug activity, and health-related quality of life. This study employed an Independent Review Committee (IRC) for radiological tumor assessments. For all tumor assessment-related efficacy variables, two analyses were performed: the primary analysis was based on Independent Review Committee (IRC) reviewed data and the secondary analysis was based on Investigator evaluation. If an endpoint was evaluated by the IRC, the IRC reviewed data is reported for this study.
The purpose of this study is to compare the effectiveness (progression free survival) of the experimental combination of carboplatin + liposomal doxorubicin with the standard combination of carboplatin + paclitaxel in first line treatment of patients with ovarian cancer. Secondary objectives are to evaluate overall survival, quality of life, objective response rate, and toxicity.
This is a phase 3, open-label, randomized study to evaluate the safety and efficacy of the Lilly/Alkermes inhaled insulin system compared to injected pre-meal insulin in non-smoking patients with type 2 diabetes. Patients will be treated for 24 months with a 2-month follow-up period.
The purpose of this clinical research study is to examine the safety and effectiveness (how well the drug works) of two different treatments for patients with melanoma. One treatment is an investigational compound (a drug that is not currently approved by the United States Food and Drug Administration [FDA]), know as Ipilimumab (also known as MDX-010 or BMS-734016) together with an approved chemotherapy drug called Dacarbazine
This study treats patients with diffuse large B-cell lymphoma whose disease is in complete remission due to previous treatment with Cyclophosphamide Doxorubicin hydrochloride Vincristine Prednisolone- Rituximab (CHOP-R). Half of the patients received Zevalin and the other half receive no further anti-cancer treatment. The two patient groups compared to determine if Zevalin given after CHOP-R therapy provides greater benefits than receiving no additional anti-cancer therapy after CHOP-R.
This study will evaluate whether anemia prevention with NeoRecormon has an additional impact on reducing cardiovascular risk over conventional anemia treatment in patients mostly with stage IV chronic kidney disease and renal anemia. The anticipated time on study treatment is 2+ years and the target sample size is 500+ individuals.
RATIONALE: Drugs used in chemotherapy, such as carboplatin and docetaxel, 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 carboplatin is more effective than docetaxel in treating patients with metastatic genetic breast cancer. PURPOSE: This randomized phase II trial is studying carboplatin to see how well it works compared to docetaxel in treating women with metastatic genetic breast cancer.
