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.
Parkinson's disease (PD) is a neurodegenerative disorder of unknown aetiology with an estimated incidence of 4.5-16/100,000 persons/year. BIA 9-1067 is currently being developed by BIAL (Portela & Cª,S.A.) to be used in addition to L-DOPA (Levodopa) /carbidopa or L-DOPA (Levodopa) / preparations in PD patients. Promising results have been obtained for BIA 9-1067 in previous studies.
This multi-center, randomized, double-blind, placebo-controlled parallel-group study will evaluate the effect of gantenerumab (RO4909832) on cognition and functioning and the safety and pharmacokinetics in participants with prodromal Alzheimer's Disease. Participants will be randomized to receive subcutaneous (SC) injections of either gantenerumab or placebo. Participants who consent to be part of the sub study will undergo positron emission tomography (PET) scanning to assess brain amyloid. The anticipated time on study treatment is 104 weeks in Part 1, with an option for an additional up to 2 years of treatment in Part 2, followed by an open-label extension (Part 3) until July 2020. The dosing for Parts 1 and 2 was stopped after a planned futility interim analysis showed a low probability of meeting the primary outcome measure with the doses studied. The study has converted to open-label to investigate higher gantenerumab doses.
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.
The purpose of this study is to identify alterations of the blood-retinal barrier (BRB) in diabetic retinas using a novel non-invasive approach based on the Fourier domain high-definition optical coherence tomograph (OCT).
This study is conducted in Europe and Asia. The aim of this observational study is to monitor antibody formation towards the room temperature stable formulation of NovoSeven® (activated recombinant human factor VII).
This study is designed to evaluate the efficacy and safety of two different dosing regimens of 0.5 mg ranibizumab given as intravitreal injection in comparison to verteporfin PDT in patients with visual impairment due to choroidal neovascularization (CNV) secondary to pathologic myopia (PM).
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.
The purpose of this study is to determine if treatment with paclitaxel plus AMG 386 is superior to paclitaxel plus placebo in women with recurrent partially platinum sensitive or resistant epithelial ovarian cancer, primary peritoneal cancer or fallopian tube cancer. AMG 386 is a man-made medication that is designed to stop the development of blood vessels in cancer tissues. Cancer tissues rely on the development of new blood vessels, a process called angiogenesis, to obtain a supply of oxygen and nutrients to grow.
Background: Endovascular thrombolysis, with or without mechanical clot removal (ET), may be beneficial for a subgroup of patients with cerebral venous sinus thrombosis (CVT), who have a poor prognosis despite treatment with heparin. Published experience with ET is promising, but only based on case series and not on controlled trials. Objective: The main objective of the TO-ACT trial is to determine if ET improves the functional outcome of patients with a severe form of CVT Study design: The TO-ACT trial will be designed as a multi-centre, prospective, randomized, open-label, blinded endpoint (PROBE) trial. Study population: Patients are eligible if they have a radiologically proven CVT, a high probability of poor outcome (defined by presence of one or more of the following risk factors: mental status disorder, coma, intracranial hemorrhagic lesion or thrombosis of the deep cerebral venous system) and the responsible physician is uncertain if ET or standard anti-coagulant treatment is better. Intervention: Patients will be randomized to receive either ET or standard therapy (therapeutic doses of heparin). ET consists of local application of alteplase or urokinase within the thrombosed sinuses, and/or mechanical thrombectomy. Glasgow coma score, NIH stroke scale and relevant laboratory parameters will be assessed at baseline. Endpoints: The primary endpoint is the modified Rankin scale (mRS) at 12 months. The most important secondary outcomes are the mRS, mortality and recanalization rate at 6 months. Major intra- and extracranial hemorrhagic complications within one week following the intervention are the principal safety outcome. Results will be analyzed according to the "intention-to-treat" principle. Assessment of study endpoints will be carried out according to standardized questionnaires by a blinded neurologist or research nurse who is not involved in the treatment of the patient. Study size: To detect a 50% relative reduction in mRS≥2 (from 40 to 20%), 164 patients (82 in each treatment arm) have to be included (two-sided alpha, 80% power). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Included patients may benefit directly from ET. Complications of ET, most notably intracranial hemorrhages, constitute the most important risk of the study.
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.
