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 study will evaluate the anti-cancer effects of crizotinib when compared with standard chemotherapy in patients with ALK positive lung cancer.
The purpose of this study is to determine the safety, tolerability, pharmacokinetics and pharmacodynamics of a single dose of ALN-TTR01 in patients with transthyretin (TTR) mediated amyloidosis (ATTR).
Primary Objective: - To demonstrate that lixisenatide can reduce cardiovascular morbidity and mortality [composite endpoint of cardiovascular (CV) death, non-fatal myocardial infarction (MI), non-fatal stroke, hospitalization for unstable angina] compared to placebo in type 2 diabetic patients who recently experienced an acute coronary syndrome (ACS) event. Secondary Objectives: To demonstrate that when compared to placebo, lixisenatide can reduce: - composite endpoint of cardiovascular death, non-fatal MI, non-fatal stroke, hospitalization for unstable angina, or hospitalization for heart failure - composite endpoint of cardiovascular death, non-fatal MI, non-fatal stroke, hospitalization for unstable angina, hospitalization for heart failure, or coronary revascularization procedure - urinary albumin excretion (based on the urinary albumin/creatinine ratio). To assess the safety and tolerability of lixisenatide.
Main Study: Primary Objective: Assess the long term safety of sarilumab in participants with rheumatoid arthritis (RA). Secondary Objective: Assess the long term efficacy of sarilumab in participants with RA. Sub-Study: This phase 3, open label sub-study was aimed to assess the usability of PFS-S when used by participants with moderate or severe RA, or their professional or non-professional healthcare providers in an unsupervised real-world situation. To mimic the real-world practice, the sub-study was incorporated into the LTS11210 study without additional visits compared to the scheduled visits in the main study. The duration of this sub-study was 12 weeks.
The purpose of this study is to identify eyes that show worsening and disease progression (progressor phenotypes).
The aim of the study is to observe and document surgical practice and evaluate patients' outcomes following a MAST™ single or double level instrumented fusion procedure using PLIF (Posterior Lumbar Interbody Fusion) or TLIF (Transforaminal Lumbar Interbody Fusion) techniques for the treatment of the degenerative lumbar spine in a "real-world" patient population.
Primary Objective: - Evaluate the rate of Atrial Fibrillation (AF) recurrences one month after randomization according to different timings of initiation of dronedarone. Secondary Objective: - Evaluate the rate of AF recurrences two months after randomization. - Assess the safety of the change from amiodarone to dronedarone - Assess dronedarone safety - Explore dronedarone and its active metabolite plasma level (in a subset of countries) - Explore potential Pharmacokinetic (PK) interaction between dronedarone and amiodarone (in a subset of countries)
This is a Phase 3 multicenter, randomized study evaluating the safety and efficacy of ramucirumab DP plus BSC as a double-blind, placebo-controlled (placebo plus BSC) comparison. Approximately 544 participants, at least 18 years of age, with Child-Pugh score < 7 and diagnosed with hepatocellular carcinoma will be randomized. Participants must have received sorafenib as first-line systemic treatment for hepatocellular carcinoma (HCC), and must have discontinued sorafenib prior to entering the study. Hypothesis: This sample size will allow differentiation of the expected increase in median overall survival (OS), from 8 months in the placebo arm to 10.67 months in the ramucirumab arm. Upon registration and completion of screening procedures, eligible participants with HCC who have disease progression during or following first-line therapy with sorafenib, or were intolerant to this agent, will be randomized to receive either ramucirumab DP or placebo. The treatment regimen will be continued until radiographic or symptomatic progression, the development of unacceptable toxicity, noncompliance or withdrawal of consent by the participant, or investigator decision.
The primary objective of this study is to evaluate the efficacy of a 200 micrograms (mcg) dose of CEP-33457 compared with placebo in participants with active systemic lupus erythematosus (SLE) as assessed by the proportion of participants achieving a combined clinical response using the SLE responder index (SRI) at Week 24.
The substances BI 201335 and BI 207127 are being developed for the treatment of chronic hepatitis C virus infection. BI 201335 and BI 207127 work by preventing the virus from replicating. The currently available medications pegylated interferon alfa and ribavirin for hepatitis C ca have considerable adverse events in patients and in many cases are not sufficiently effective. This is particularly the case in treatment of patients infected with genotype 1 of HCV. A combination therapy of these new substances without pegylated interferon alfa may be associated with fewer adverse events that currently available (pegylated interferon-alfa-based) medication and may also provide a treatment option to the large number of patients with contraindications or intolerance to pegylated interferon alfa. This clinical trial (1241.21) currently consists of 3 distinct studies: Part 1, Part 2 and Part 3. Part 1 (SOUND-C1) is a 2 armed study as described in experimental arms 1 and 2 below (actual enrollment: 56 patients; randomized and treated: 32) Part 2 (SOUND-C2) is a 5 armed study as described in experimental arms 3 to 7 below (actual enrollment: 465; randomized and treated: 362) Part 3 (SOUND-C3) includes 3 arms as described in experimental arms 8 to 10 below (83 patients randomized and treated)
