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 assess the effect of rimonabant treatment on the histological features of NASH in patients with Type 2 diabetes.

This study will evaluate if extended therapy with oral rivaroxaban can prevent blood clots in the leg and lung that can occur with patients hospitalized for acute medical illness, and compare these results with those of the standard enoxaparin dose and duration regimen. The safety of rivaroxaban will also be studied.
This is an observational safety study being conducted in Europe comparing patients taking Xagrid to patients taking other cytoreductive treatments. The plan is to enrol at least 750 subjects taking Xagrid with up to 3000 subjects taking other cytoreductive therapies. The study will collect follow up data for 5 years for each patient enrolled that will focus on collecting data related to pre-defined events (PDEs) and Suspected Serious Adverse Reactions (SSARs).
The primary objective of this study is to evaluate the efficacy of SSR240600C in women with overactive bladder compared to placebo using tolterodine as a study calibrator.
This is a randomised, double-blind, double-dummy, multinational, multicentre, parallel group trial comparing tiotropium (18 mcg) inhalation capsule via HandiHaler and salmeterol (50 mcg) via MDI in patients with COPD. There will be a two-week run-in period followed by a 52-week randomised treatment phase. Patients who withdraw prematurely from trial medication will be encouraged to remain in the trial and participate in follow-up telephone contacts until their predicted normal exit date from the trial (i.e. 52 weeks after taking the first dose of randomised treatment). The phone calls will be made at all scheduled visits. The primary objective of this study is to compare the effect of tiotropium (18 mcg) inhalation capsule via HandiHaler with that of salmeterol (50 mcg) via MDI on COPD exacerbations. The primary endpoint is time to first COPD exacerbation during the 52 week randomised treatment period. A COPD exacerbation will be defined as a complex of respiratory events / symptoms (increase or new onset) of more than one of the following: cough, sputum, wheezing, dyspnoea or chest tightness with at least one symptom lasting at least three days requiring treatment with antibiotics and/or systemic steroids and/or hospitalisation. The onset of an exacerbation is defined as the onset of the first new or increased reported symptom. The end of the exacerbation should be recorded as defined by the investigator. Only COPD exacerbations with onset during randomised treatment will be included in the analysis.
This protocol is designed to assess the efficacy and safety of inotuzumab ozogamicin given with rituximab compared to a defined investigator's choice therapy. Subjects will be randomized to one of these two arms of the study.
The primary objective of this study is to evaluate the efficacy of 400 mg QD nevirapine extended release (NVP XR) formulation versus 200 mg BID nevirapine immediate release (NVP IR) in ARV therapy naïve HIV-1 infected patients after 48 weeks of treatment. Secondary objectives are to evaluate safety and pharmacokinetics of NVP XR and NVP IR.
Lung cancer is the leading cause of cancer deaths worldwide. It is estimated that, in 2004, 173,700 new cases of lung cancer will be diagnosed in the United States alone and 164,440 deaths due to this disease will occur(13) . NSCLC accounts for approximately 80% of all lung cancers. Among NSCLC cases approximately 30% present with locally advanced and 40% with metastatic disease (14,15) . In metastatic disease, chemotherapy is the treatment of choice, but benefits obtained in survival have been modest. Five-year survival is less than 15%, probably due to diagnosis at late stages. Surgical results in earlier stages are poor compared to other tumor types (about 40% of recurrence in stages I-II). Results of chemotherapy in advanced stages are also poor (one-year survival of 40%) (15,17). It is commonly accepted that the standard treatment for advanced disease (stage IV and IIIb with malignant pleural effusion) consists of platinum-based chemotherapy(15,16) . However, there are many open questions in the management of these patients, such as the role of 3-drugs combinations, non-platinum-based therapies, and new biologic therapeutics' approaches. Currently, in the treatment of advanced NSCLC response rates of about 20%-30% and median survival times of 6 to 11 months have been achieved (16, 17, 18, 19, 20, 21, 22,). Several combinations of drugs are used and show similar efficacy. Cisplatin plus vinorelbine or Cisplatin plus Gemcitabine are among the most commonly used regimens in the first-line therapy of NSCLC.
The purpose of this study is to determine the effect of AZD0530 on subjects with breast cancer or prostate cancer with metastatic bone disease in comparison to zoledronic acid.
