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.
The purpose of this trial is to study the effect of Memantine (uncompetitive, moderate affinity, NMDA receptor antagonist that binds to the NMDA receptor channel, and regulates the calcium influx into the neurons), a drug used to treat Alzheimer´s disease, on the progression of Amyotrophic Lateral Sclerosis (ALS). Memantine is added to riluzole (the single drug approved to treat ALS).
Rosiglitazone (RSG) has been tested in clinical studies and is approved by the FDA as a treatment for type II diabetes mellitus, a disease that occurs when the body is unable to effectively use glucose. RSG XR, the investigational drug used in this study, is an extended-release form of RSG. This study tests whether RSG XR safely provides clinical benefit to people with mild to moderate Alzheimer's disease (AD) when combined with the currently approved AD medication, Aricept (donepezil). RSG XR is a new approach to AD therapy and this study tests a new way to treat AD by testing whether one's genetic makeup affects their response to the study drug. Clinical data suggesting that RSG may benefit AD patients was first seen in a small study performed at the University of Washington and then from a larger GSK study conducted in Europe and New Zealand. In the first study, subjects receiving RSG once daily for 6 months scored significantly better on 3 tests of memory and thought than those who did not receive RSG. In the GSK study, those that appeared to benefit most from treatment with RSG XR had a specific genetic pattern. They did not have the gene that caused them to produce the protein apolipoprotein E e4 (APOE e4). Subjects who have the APOE e4 gene may have two copies, one from each parent, or they may have only one APOE e4 gene meaning that they inherited either the APOE e2 or APOE e3 version of the gene, instead of APOE e4, from one of their parents. Subjects with one copy of the APOE e4 gene remained at their same level of thinking ability while those with two copies of the APOE e4 gene, continued to worsen during the 6-month treatment. The current study will more directly test the effectiveness or RSG XR on people who either have or lack the APOE e4 gene.
The main purpose of this protocol is to evaluate the long-term safety of pregabalin in patients who participated in the previous fibromyalgia Study A0081100 and who wish to receive open-label pregabalin therapy.
Objectives are to evaluate whether idrabiotaparinux (SSR126517E) is as least as effective as a standard warfarin treatment to prevent recurrence of venous thromboembolic events (VTE) in patients with symptomatic pulmonary embolism (PE) with or without symptomatic deep venous thrombosis (DVT) and to assess its safety (bleedings) versus warfarin.
This study assessed the safety, tolerability, and efficacy of 2 doses of oral fingolimod versus interferon β-1a to reduce the frequency of relapses in patients with relapsing-remitting multiple sclerosis.
Study to evaluate the utility of prospective HLA-B*5701 screening on the incidence of abacavir hypersensitivity (ABC HSR) in 1800 previously ABC-naive adults with HIV-1 from Europe, Australia and other countries as applicable. The study has two (co-primary) objectives: i) to determine if screening for HLA-B*5701 prior to ABC-containing HAART results in a lower incidence of clinically-suspected HSR versus current standard of care (no genetic screening) and ii) to determine if screening for HLA-B*5701 prior to ABC-containing HAART, results in a significantly lower incidence of immunologically-confirmed HSR versus current standard of care (no genetic screening or patch testing). The study consists of up to a 28-day screening period, a randomised observation period (Day 1 through Week 6) and, for subjects experiencing a suspected ABC HSR and a subset of ABC-tolerant subjects, an epicutaneous patch test (EPT) assessment period. Eligible subjects will be randomised to one of two study arms: a Current Standard of Care Arm (no prospective genetic screening: Control) and a Genetic Screening Arm (prospective genetic screening). Subjects identified as HLA-B*5701 positive in the prospective Genetic Screening Arm will not receive ABC and will be excluded from further study. Subjects who experience suspected ABC HSR during the 6-week observation will be withdrawn from ABC-containing product and undergo EPT patch testing 6 weeks later.
This study will provide pre-approval drug access to lapatinib, in combination with capecitabine, to patients whose breast cancer had progressed on other therapies
This is a multicenter, 6 months open label safety extension study for all patients who are willing and eligible to continue from the pivotal, double-blind S308.3.003 trial
This is a multicenter, randomized, double blind, parallel group study of 6 months' treatment with SLV308 as monotherapy in patients with early stage PD. An open label safety extension to this study is planned as a separate protocol for patients who are willing and eligible to participate.
The primary objective of this study will be to provide further evidence of the long-term safety and tolerability of levodopa-carbidopa intestinal gel (Duodopa®) over 12-months in participants with advanced Parkinson's disease (PD) and severe motor fluctuations.
