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.
This registry is a clinical post-market evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES).
The objective of this study is to assess the safety and effectiveness of the automatic atrioventricular (AV) delay and interventricular (VV) delay optimization algorithm used in the PARADYM RF SONR Cardiac Resynchronization Therapy with Defibrillation (CRT-D) device (Model 9770) in combination with the SonRtip Lead, which includes a SonR sensor in the tip of the atrial pacing lead, and compatible SmartView programming software. This study will evaluate the effectiveness of the automatic optimization algorithm in increasing the rate of patients responding to the therapy as compared to an echocardiographic optimization method. This study will also evaluate the safety and effectiveness of the SonRtip atrial pacing lead.
Patients with an ulcerated melanoma with Breslow >1 mm, N0M0 have a significantly higher risk for relapse than patients with a non-ulcerated primary and about a 40-50% chance of developing stage IV disease to which they will almost invariably succumb. In stage I and II patients with an ulcerated primary who have been sentinel node (SN-staged) and found to be SN-negative there is still a 25-30% relapse risk. The purpose of this study is to evaluate the effectiveness and safety when treated with PEG IFN alfa-2b for 2 years as compared to observation (no treatment), administered after adequate surgery has been performed for ulcerated primary cutaneous melanomas.
To prospectively evaluate in a multicenter open label trial whether the use of zotarolimus-eluting ENDEAVOR Stent implantation in patients at low restenosis or at high bleeding or thrombotic risk will decrease the incidence of 12-month major adverse cardiac events (MACE) including overall death, any myocardial infarction (MI) or any target vessel revascularization (TVR).
The purpose of this study is to find out which way of giving high-dose radiation works best for treatment of cancer that has spread to bone, the spine, soft tissue, or lymph nodes. This study will look at the effects, good and/or bad, of giving 27 Gy in three fractions (3 days) or 24 Gy in one fraction (1 day) using image-guided intensity-modulated radiotherapy (IG-IMRT). IG-IMRT is radiation that is given directly to the cancer site and reduces the exposure to normal tissue. Currently there are no studies that compare the effects of giving radiation in either hypofractionated doses (higher total doses of radiation spread out over several treatment days) or a single-fraction dose (entire radiation dose given in one treatment session). The patient may be asked to participate in an additional part of this study where we will get a a (DW/DCE) MRI before treatment start and within one hour after radiation treatment. If the patient is asked to take part in this portion of the study, all they will need to do is get up to 3 MRIs with standard contrast injection. The purpose of this is to see if as a result of the treatment there are changes in the blood flow going to the cancer which could suggest that the treatment may be successful. In addition some patients can present new lesions and may be asked if they would like to have these new lesions treated on the protocol. If they are given this option, this will not extend their follow up period. The follow up of the new lesions will match with the prior follow up dates.
Study phase: phase III Study objective: - Comparison of Bortezomib, Melphalan, Prednisone (VMP) with High Dose Melphalan followed autologous stem cell transplantation (ASCT) - Comparison of Bortezomib, Lenalidomide, Dexamethasone(VRD) as consolidation versus no consolidation - Comparison of single versus tandem high dose Melphalan with ASCT Patient population: Patients with symptomatic multiple myeloma,previously untreated, ISS stages 1-3, age 18-65 years inclusive Study design: Prospective, multicenter, intergroup, randomized Duration of treatment: Expected duration of induction, stem cell collection and intensification is 6 - 9 months. Consolidation with VRD will last 2 months Maintenance therapy with Lenalidomide will be given until relapse. All patients will be followed until 10 years after registration.
This study is carried out to see how Caucasian patients with lung cancer which has EGFR mutation will respond to gefitinib (IRESSA™) as a first line treatment. Safety data will also be collected and analysed to confirm that treatment with gefitinib is safe and well tolerated.
RATIONALE: Collecting and storing samples of tumor tissue, blood, bone marrow, and other body fluids from patients to test in the laboratory and collecting information about the patient's health and treatment may help doctors learn more about cancer and help the study of cancer in the future. Studying these samples in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is collecting and looking at blood and tissue samples in children with newly diagnosed acute lymphoblastic leukemia.
Rationale: Gathering medical information and tumor samples from patients with male breast cancer may help doctors learn more about the disease. Purpose retrospective part: to perform a large international retrospective analysis of clinical and biological data of male BC patients treated in the participating centers from 1990 to 2010. Purpose prospective part: to create a registry of men with breast cancer for a period of 30 months (starting early 2014).
The research study is testing the investigational drug necitumumab (IMC-11F8) in the treatment of advanced non-small cell lung cancer. The aim of this study is to determine if necitumumab, given together with a standard chemotherapy combination consisting of cisplatin and gemcitabine will be more effective in improving participant disease than the standard chemotherapy combination alone.
