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 establish efficacy of Idalopirdine as adjunctive therapy to donepezil for symptomatic treatment of patients with mild-to-moderate Alzheimer's disease (AD).
The purpose of this Clinical investigation is to assess the impact of the Multi Point Pacing (MPP) feature at 12 months in the treatment of patients not responding to standard Cardiac Resynchronization Therapy (CRT) after 6 months.
Primary Objective: The primary objective of this phase 2/3 study is to evaluate the efficacy of olipudase alfa (recombinant human acid sphingomyelinase) administered intravenously once every 2 weeks for 52 weeks in adult participants with acid sphingomyelinase deficiency (ASMD) by assessing changes in: 1) spleen volume as measured by abdominal magnetic resonance imaging (MRI) (and, for the United States [US] only, in association with participant perception related to spleen volume as measured by splenomegaly-related score [SRS]); and 2) infiltrative lung disease as measured by the pulmonary function test, diffusing capacity of the lung for carbon monoxide (DLCO). Secondary Objectives: - To confirm the safety of olipudase alfa administered intravenously once every 2 weeks for 52 weeks. - To characterize the effect of olipudase alfa on the participant perception related to spleen volume as measured by the SRS after 52 weeks of study drug administration. (For the US, the effect of olipudase alfa on the SRS is part of the primary objective). - To characterize the effect of olipudase alfa after 52 weeks of study drug administration on the following outcome measures assessed sequentially: - The effect of olipudase alfa on liver volume; - The effect of olipudase alfa on platelet count; - The effect of olipudase alfa on fatigue; - The effect of olipudase alfa on pain; - The effect of olipudase alfa on dyspnea.
The purpose of this study is to collect patient related benefit data following treatment for permanent hearing loss with a hearing implant from the company Cochlear over a period of 2 years post treatment. Assessment of benefits is based on standard questionnaires of hearing ability and quality of life in general.
To determine the optimal route of administration, dose level, and safety of intravenous and subcutaneous dosing of sotatercept for maintaining hemoglobin levels in subjects who are on hemodialysis.
This study will assess the efficacy and safety of adding Herceptin to a paclitaxel-containing regimen followed by cyclophosphamide/methotrexate/fluorouracil (CMF) chemotherapy in women with locally advanced breast cancer and HER2/c-erbB-2 gene amplification. In a parallel observational study patients with HER2-negative disease will receive the same chemotherapy without Herceptin.
This multicenter, open-label study will evaluate the efficacy and safety of subcutaneously administered RoActemra/Actemra (tocilizumab) as monotherapy or in combination with methotrexate or other non-biologic DMARDs in patients with active rheumatoid arthritis and an inadequate response to non-biologic DMARDs or to one anti-TNF. In Phase 1, all patients will receive RoActemra/Actemra 162 mg subcutaneously (sc) weekly for Weeks 1 to 24, with or without methotrexate or other non-biologic DMARDs. For Part 2, patients who achieve sustained clinical DAS28-ESR remission at Weeks 20 and 24 will be randomized to receive RoActemra/Actemra 162 mg sc either weekly or every 2 weeks for Weeks 24 to 48, with or without methotrexate or other non-biologic DMARDs. Patients who do not achieve sustained clinical remission but achieve low disease activity (DAS-ESR </= 3.2) will continue the initial treatment of RoActemra/Actemra 162 mg sc weekly for Weeks 24 to 48, with or without methotrexate or other non-biologic DMARDs.
The current study will compare the efficacy, safety, pharmacokinetics and immunogenicity of PF-05280014 in combination with paclitaxel versus trastuzumab sourced from the European Union (trastuzumab-EU) with paclitaxel in female patients with HER2-positive, metastatic breast cancer in the first-line treatment setting. The hypothesis to be tested in this study is that the efficacy (ORR) of PF-05280014 is similar to trastuzumab-EU.
The main goal of this study is to evaluate the efficacy and safety of glycopyrronium bromide and indacaterol maleate and glycopyrronium bromide fixed dose combination (FDC) in patients with moderate COPD who switch from their current COPD therapy. This study aims to provide data on how non-exacerbating, but still symptomatic patients with moderate COPD switching from their current COPD treatment to glycopyrronium bromide or indacaterol maleate and glycopyrronium bromide FDC maintain or improve their symptoms. Another purpose of this study is to increase awareness and usage of validated COPD symptoms tools and dyspnea questionnaires in order to facilitate clinical assessment and improve early diagnosis of symptomatic patients.
Background: The Portuguese National Health Directorate has issued clinical practice guidelines on prescription of anti-inflammatory drugs and COX-2 inhibitors, acid suppressive therapy and proton pump inhibitors, and anti-platelets. However, their effectiveness in changing actual practice is unknown. The objectives will be to compare the effectiveness of educational outreach visits in the implementation of clinical guidelines in primary care in Portugal against usual implementation strategies and to conduct a cost-effectiveness analysis of this method. Methods: The trial will be a parallel, cluster-randomized, unblinded, trial in primary care, with a 1:1 allocation ratio. This study will assess the effect of educational outreach visits on physician compliance with prescription guidelines. The general study hypothesis is whether educational outreach visits are superior to usual implementation of guidelines regarding the reduction of inappropriate prescribing (compliance with prescription guidelines). All National Health Service primary care units in the Lisbon (Portugal) region will be invited to participate. Units will be eligible if they are using an Electronic Health Record to issue prescriptions and have at least four doctors willing to participate. Doctors in intervention units will receive three educational outreach visits (one for each guideline) during a six months period, while the control group doctors will be offered an unrelated group training session (on using the international classification for primary care). Intervention visits will be one on one 15 minutes discussions conducted by guideline authors or trained family physicians at the physician's workplace. There are two primary outcomes, measured at the physician's level. One is the proportion of COX-2 inhibitors prescribed within the entire NSAID class, in defined daily doses 18 months after the intervention. The other is the proportion of omeprazole within the entire proton pump inhibitors class, in defined daily doses at 18 months post-intervention. Prescription data will be collected from the regional pharmacy claims database.
