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 study is to evaluate the efficacy of gevokizumab in reducing the risk of recurrent uveitic disease in subjects with non-infectious uveitis whose disease is currently controlled with systemic treatment.
The European population is aging rapidly which poses a challenge on the individual, the European societies, and health care systems. Among the most promising public health interventions that may extend healthy life expectancy at older age are vitamin D, marine omega-3 fatty acids and physical exercise. However, their individual and combined effects have yet to be confirmed in a clinical trial. The broad aim of DO-HEALTH is to prolong healthy life expectancy in European seniors. The specific aim is to establish whether vitamin D, omega-3 fatty acids, and a simple home exercise program will prevent disease at older age. To achieve these aims, DO-HEALTH will enroll 2152 community-dwelling men and women who are 70 years and older, an age when chronic diseases increase substantially. The DO-HEALTH seniors will be recruited from 7 European cities (Zurich, Basel, Geneva, Toulouse, Berlin, Innsbruck and Coimbra) and will be randomized in a 2x2x2 factorial design trial to a simple home exercise program and/or vitamin D, and/or omega-3 fatty acids, over a 3 year period. This will allow to test the individual and the combined benefit of the interventions in the prevention of 5 primary endpoints: incident non-vertebral fractures; functional decline; systolic and diastolic blood pressure change; cognitive decline; and the rate of any infection. Key secondary endpoints include incidence of hip fractures, rate of falls, severity of pain in symptomatic knee osteoarthritis, gastro-intestinal symptoms, mental and oral health, quality of life, and mortality. All clinical endpoints will be supported by a large DO-HEALTH biomarker study to evaluate the effect of the interventions at the cellular level of multi-organ function. DO-HEALTH will further evaluate reasons why or why not seniors adhere to the 3 interventions, and will assess their cost-benefit in a health economic model based on documented health care utilization and observed incidence of chronic disease. website DO-HEALTH: http://do-health.eu/wordpress/
This study aimed to assess the optimal duration of nilotinib 300 mg twice daily (BID) consolidation treatment in patients with Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML), in order that patients remained in treatment-free remission (≥MR4.0) without molecular relapse 12 months after starting the Treatment-Free Remission (TFR) phase.
Clinical study to assess the efficacy, safety, and tolerability of macitentan in subjects with Eisenmenger Syndrome.
This open-label, multicenter, non-randomized study provided continued access to vemurafenib for eligible participants with BRAF V600 mutation-positive malignancy, who were previously enrolled and treated in an antecedent vemurafenib protocol and did not meet the protocol's criteria for disease progression, or were treated beyond progression and were still deriving clinical benefit (as assessed by investigator), and may have therefore potentially benefited from continued treatment with vemurafenib. Participants received treatment with oral vemurafenib at 960 milligrams (mg) twice daily (BID), 720 mg BID, or 480 mg BID, depending on the last dose in the antecedent protocol. Treatment continued until progression of disease or as long as the participant was deriving clinical benefit, as judged by the investigator (case-by-case decision with approval of the Medical Monitor), death, withdrawal of consent, unacceptable toxicity, loss to follow-up, or decision of the Sponsor to terminate the study, whichever occurred first.
Long-term study to evaluate if macitentan is safe, tolerable and efficient enough to be used for treatment of Eisenmenger syndrome.
An adnexal mass is the most common indication for gynaecological surgery . Pre operative characterization is crucial and a scoring system would be useful to standardize the imaging report and thus, improve patient management. Recently, our center developed the first MR scoring system named ADNEXMR SCORING system in a retrospective study which is accurate and reproducible (1). Our objectives are to perform an external prospective validation of this scoring system, to evaluate its potential impact on therapeutic strategy and to test its reproducibility. This is a prospective large multicenter study. All patients with a sonographically indeterminate adnexal mass referred for MR imaging will be consecutively included in each center. Then, patients will undergo a routine pelvic MR imaging. Prospectively, one senior and one junior radiologists independently analyze the different MR criteria to characterize adnexal masses. The MR report will be issued as standard and the patient will be managed accordingly. Then, the reader will classify the mass using ADNEXMR SCORING system. The classification will be compared to the reference standard as defined below. The reproducibility of the classification will be tested between the junior and the senior radiologist. After anonymisation, images will be analyzed by another senior radiologist of another center blinded from any clinical or ultrasonographical data and correlated with the reference standard. Reference standard: Reference standard will be surgical procedure with histology or standard clinical follow-up depending on most appropriate routine practice. Sample size: The sample size was computed to ensure a power of at least 90% (with a two-sided type I error rate of 5%) to conclude that SCORE 2 and 3 and SCORE 4 and 5 would have a different PPV. It would thus be necessary to have at least 569 patients classified as SCORE 2, 259 as SCORE 3, 52 as SCORE 4 and 51 as SCORE 5 (18). Given the prevalences, and assuming 6% of patients would be classified, as SCORE 1 and 10% would be lost to follow-up, 1340 patients will be included in this study to insure a probability of at least 95% to obtain the aforementioned number of patients in each score category. The inclusion period will last 18 months (extension for a period of 12 months) and monitoring will continue for 2 years. Thomassin Naggara I., et al.

The purpose of this study is to evaluate the efficacy and safety of inotersen given for 65 weeks in participants with Familial Amyloid Polyneuropathy (FAP).
This non-interventional study will evaluate the efficacy, tolerability, health related quality of life and use of health resources associated with QUTENZA treatment when QUTENZA is used in standard clinical practice. The patient's primary diagnosis of peripheral neuropathic pain (PNP) will be classified into subtypes: post-herpetic neuralgia (PHN); HIV-associated neuropathy (HIV-AN); neuropathic back pain; cancer-related neuropathic pain; post-operative & post-traumatic neuropathic pain; and 'other' neuropathies.
The study is to demonstrate non-inferior thyroid remnant first ablation success of Thyrogen and 131I compared to thyroid hormone withdrawal (THW) and 131I in patients with T4 tumour based on historical diagnostic whole body scan (DxWBS) records.
