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.
Primary objective: To demonstrate the clinical efficacy of otamixaban (dose effect via 5 intravenous [IV] regimens) in patients with moderate-to-high-risk non-ST elevation acute coronary syndromes (ACS) and planned early invasive strategy. Secondary objectives: To evaluate safety and assess pharmacokinetics (PK) and pharmacodynamics (PD).
The purpose of this study is to determine whether treatment with esomeprazole for 6 months will improve asthma in adult patients with moderate to severe asthma and symptoms of gastroesophageal reflux disease.
The primary purpose of the study is to investigate the anti-dyskinetic effect of several doses of sarizotan in Parkinson patients in order to generate information on the dose-response relationship (dose-finding).
The purpose of this study is to determine if the combination of VELCADE and rituximab improves progression free survival relative to rituximab alone in patients with relapsed or refractory B-cell non-Hodgkin's lymphoma (B-NHL) who never received rituximab or who have previously responded to rituximab. This is an international study being conducted in the United States and in many countries around the world. A complete list of study locations is listed below.
The aim of the present study is to identify factors (such as symptom patterns and symptom scores) that influence the response to treatment with pantoprazole using different evaluation methods (e.g., ReQuest™ questionnaire, patient and investigator assessment). Pantoprazole will be administered once daily in the morning at one dose level. The study duration consists of a treatment period of 8 weeks. The study will provide further data on safety and tolerability of pantoprazole.
This large phase III clinical study is studying the effect of vandetanib (ZACTIMA) in treating non-small cell lung cancer (NSCLC). Vandetanib is a new type of agent that targets the blood supply to a cancer tumour (through it's anti-vascular endothelial growth factor receptor (VEGFR) properties) and the tumour cells themselves (through it's anti-endothelial growth factor receptor (EGFR) actions). This study will look at the effects of vandetanib in lung cancer patients who have had their cancer re-appear after treatment with standard chemotherapy. This clinical study will test if the vandetanib anti-VEGF and anti-EGFR characteristics can deliver longer improved progression free survival and improved overall survival than docetaxel (Taxotere) alone. All patients participating this clinical study will receive treatment with docetaxel, a commonly used treatment for recurrent non-small cell lung cancer. In addition, some patients will also receive vandetanib (ZACTIMA), an anti-EGFR / anti-VEGF agent. Recent clinical research shows that vascular endothelial growth factor receptor (VEGFR) inhibition, when used with standard chemotherapy, can lead to increased survival in advanced non-small cell lung cancer (NSCLC) patients. Other research shows that epidermal growth factor receptor (EGFR) inhibitors, like erlotinib (Tarceva) can also increase overall non-small cell lung cancer survival by killing tumour cells and stopping them from dividing.
Primary objective : - To compare disease-free survival after treatment with docetaxel in combination with doxorubicin and cyclophosphamide to doxorubicin and cyclophosphamide followed by docetaxel in operable adjuvant breast cancer HER2neu negative patients with positive axillary lymph nodes. Secondary objectives : - To compare toxicity and quality of life between the 2 above-mentioned arms. - To evaluate pathologic and molecular markers for predicting efficacy.
This study is to assess the safety and efficacy of an add-on treatment algorithm with olmesartan, hydrochlorothiazide and amlodipine in patients with mild to moderate hypertension.
Trial 42603ATT3004 is an open-label extension study to clinical trial 42603ATT3002 (NCT00246220). In trial 42603ATT3002 the efficacy and safety of OROS methylphenidate was assessed in adult subjects with Attention Deficit Hyperactivity Disease (ADHD). ADHD is a developmental disorder beginning in childhood and characterized by developmentally inappropriate inattention, hyperactivity and impulsiveness. Data on the number of adult patients with ADHD is limited, but it is estimated that approximately 50% of children with ADHD will have symptoms also in adhulthood. The drug tested in this trial is OROS methylphenidate. The active ingredient is methylphenidate and the tablet is designed to release the active ingredient gradually to ensure an effect, which lasts up to 12 hours. Trial 42603ATT3002 consisted of a 5-week period, where subjects were assigned to either receive placebo (empty drug) or one out of three different dosages of OROS methylphenidate. This 5-week period was followed by a 7-week period, where patients received OROS methylphenidate at their optimal dose. In study 42603ATT3004, subjects who complete 42603ATT3002 are followed for a period of at least 52 weeks to evaluate safety and tolerability of OROS methylphenidate in patients who are treated with OROS methylphenidate over a long period of time. Amendment: At the end of the open-label period of the present study 42603ATT3004, patients are enrolled into a double-blind placebo-controlled period, which lasts an additional 4 weeks. The purpose of this double-blind placebo-controlled period is to evaluate the maintenance of effect under continued treatment with OROS methlyphenidate in comparison to treatment cessation in those patients, who are randomized into the placebo-group.
To study the safety and effectiveness of several doses of PD 0348292 compared to enoxaparin in preventing blood clots in the lungs or deep leg veins of patients after knee surgery
