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 trial is to determine the comparative safety and efficacy of dabigatran etexilate 150 mg bid administered orally and warfarin as needed (pro re nata - prn) to maintain an International Normalised Ratio (INR) of 2.0-3.0 for 6 month treatment of acute symptomatic venous thromboembolism (VTE), following initial treatment (5-10 days) with a parenteral anticoagulant approved for this indication. This trial aims to demonstrate non-inferiority of dabigatran compared with warfarin in patients with acute symptomatic VTE. After achieving non-inferiority, this trial also aims to establish superiority (by means of hierarchical tests) of dabigatran over warfarin.
Study is to compare antifungal prophylaxis of Voriconazole and Itraconazole in subjects who have had a Stem Cell Transplant. The success of the end point will be measured using evidence of Infection, drug compliance and survival.
Patients will be randomised to receive either placebo or the study drug for a period of 30 weeks, in addition to their standard Parkinsonian medications. During the first 8 weeks, the patient's levodopa doses may be adjusted if necessary by the investigator. For the remainder of the 22 weeks, all medications should be kept stable. Patients will be required to attend the clinic twice during the screening period and then a further 8 times during the treatment period. They will be required to complete home diaries where they will record their motor function. In addition, their doctor will assess their Parkinson's disease during the clinic visits. There will also be blood draws for safety and pharmacokinetic and pharmacogenomics evaluation. Following the treatment and assessment period, they will return to the clinic one month later for follow up.
In Patients with metastatic colorectal cancer the following treatments first-line Folfiri+Cetuximab first-line Folfox6 + Cetuximab will be concerning efficacy and safety. The trial compares Folfiri + Cetuximab and Folfox6 + Cetuximab concerning efficacy and safety as first
The primary objective is to assess the antihypertensive efficacy of 4 different AVE 7688 doses on the change from baseline in trough diastolic blood pressure at the end of week 12. The secondary objectives are: - To assess the antihypertensive efficacy of 4 different AVE 7688 doses on the change from baseline in trough systolic blood pressure at the end of week 12 - To compare the percentages of responders after 12 week of treatment - To evaluate the long term safety and tolerability of AVE 7688 with particular attention to angioedema
To assess the impact on glucose control by inhaled insulin in patients with type 2 diabetes who are not well controlled on 2 or more oral anti-diabetic agents
The purpose of this study is to assess whether Lyrica is a safe and effective treatment for partial epilepsy in comparison with an established treatment, Lamictal.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This clinical trial is studying giving radiation therapy or combination chemotherapy to see how well it works in treating patients with clinically or radiologically progressive low-grade gliomas.
To evaluate the FOLFOX regimen versus LV5FU2 in the adjuvant treatment of stage II and III colon cancer. Primary objective: Disease Free Survival (DFS) Secondary objective: Overall Survival (OS), safety (including long term toxicity)
The objective of the study was to evaluate the degree of improvement in lung function in patients with chronic obstructive pulmonary disease (COPD) after treatment with tiotropium inhalation capsules compared to salmeterol inhalation aerosol .
