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 extension trial was to further evaluate the safety and tolerability of oral cladribine in subjects who have previously completed treatment within Trial 25643 (CLARITY). This trial also explored clinical benefit of prolonged 192-week versus 96-week treatment.
The objective of the current study is to investigate the efficacy, safety and tolerability of BI 1356 (Linagliptin) (5 mg / once daily) compared to placebo given for 24 weeks as initial combination therapy with pioglitazone 30 mg in patients with type 2 diabetes mellitus with insufficient glycaemic control.
Heparin is the reference therapy for most patients with pulmonary embolism. Some patients with sub-massive pulmonary embolism defined by normal blood pressure and dysfunction of the right ventricle have a higher mortality risk. It has been suggested that thrombolytic treatment, a drug that dissolves blood clots more rapidly, may reduce the mortality in those patients. The studies reported to date were unable to confirm or refute this hypothesis because the number of patients included in those studies is too low. The aim of the study is to compare thrombolytic treatment with heparin (which is the reference therapy for pulmonary embolism) in a large group of patients with sub-massive pulmonary embolism.
To evaluate the steady-state systemic plasma concentrations of latanoprost acid following administration of latanoprost 0.005% (1.5 ug) in pediatric and adult subjects with glaucoma or ocular hypertension.
This study is a phase III, double-masked, randomized, study of the efficacy and safety of VEGF Trap-Eye in patients with neovascular age-related macular degeneration. Approximately 1200 patients will be randomized in Europe, Asia, Japan, Australia and South America.
The purpose is to evaluate the effects of an investigational blood thinner, apixaban, in preventing venous thromboembolic (VTE) recurrence or death in patients who have completed their intended treatment for deep vein thrombosis (DVT) or pulmonary embolism (PE)
Primary objective: Comparison of independently assessed progression free survival (PFS) in subjects administered Bevacizumab + Temsirolimus vs. those administered Bevacizumab + Interferon-Alfa. Secondary objectives: safety, Investigator assessed PFS, objective response rate (independently assessed), and overall survival.
THAOS is a global, multi-center, longitudinal observational survey open to all patients with transthyretin amyloidosis (ATTR), including ATTR-PN (polyneuropathy), ATTR-CM (cardiomyopathy) and wild-type ATTR-CM. It is open-ended with a minimum duration of 10 years. Patients will be followed as long as they are able to participate. The principal aims of this outcome survey are to better understand and characterize the natural history of the disease by studying a large and heterogenous patient population. Survey data may be used to develop new treatment guidelines and recommendations, and to inform and educate clinicians about the management of this disease.
Enthuse M1C is a large phase III clinical trial studying the safety and efficacy of ZD4054 (Zibotentan) in combination with docetaxel (Taxotere) in patients with metastatic hormone resistant prostate cancer (HRPC). This clinical trial will test if the Endothelin A Receptor Antagonist ZD4054 (Zibotentan) can further improve survival compared with docetaxel alone. ZD4054 (Zibotentan) is a new type of agent, which is thought to slow tumour growth and spread by blocking Endothelin A receptor activity. This trial will look at the effects of ZD4054 (Zibotentan) in hormone resistant prostate cancer patients with bone metastases compared with docetaxel. All patients participating in this clinical trial will receive docetaxel chemotherapy, which is a commonly used chemotherapy to treat prostate cancer in addition to other existing prostate cancer therapies. Half the patients will receive ZD4054 (Zibotentan), and half the patients will receive placebo in addition to docetaxel and other prostate cancer therapy. By participating in this trial there is a 50% chance that patients will receive an agent that may further slow the progression of the tumour. No patients will be deprived of standard prostate cancer therapy.
To demonstrate a reduction in the number of ventricular therapies (ATP and Shocks) delivered for treating spontaneous arrhythmia episodes with a fast cycle length (CL≤ 320ms) as a consequence of self-termination and better arrhythmia discrimination due to a greater number of R-R intervals necessary to detect ventricular events.
