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.
To compare the health outcome of patients with schizophrenia, who are at risk for relapse, when treated with a long acting injection form of olanzapine versus treatment with oral olanzapine.
The purpose of this study is to compare the efficacy of dasatinib with that of high-dose (800-mg) imatinib in participants with chronic phase chronic myeloid leukemia who achieved only a suboptimal response after at least 3 months of monotherapy with 400-mg imatinib. The safety of these treatments will also be evaluated.
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.
