There are about 21071 clinical studies being (or have been) conducted in Spain. 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.
Background: Despite preoperative screening, technical improvements and increased patient monitoring, perioperative myocardial infarction (PMI) remains the first cause of morbidity and mortality within 30 days after surgery. Moreover, the available evidence indicates worrying rise of risk in postoperative patients with only elevated troponins reflecting cardiac injury, but without a conventional clinical diagnosis of myocardial infarction according to current definition. Worldwide, annually approximately 300 million adults undergo major non cardiac surgery and 10 million of them are estimated to suffer a myocardial injury after non-cardiac surgery (MINS), defined as a prognostically relevant increase of a troponin T peak of 0.03 ng/ml or greater. Many of the patients with MINS does not fulfill the universal definition of myocardial infarction, rarely experience ischemic symptoms and their prognosis is very poor (1 out of 10 die at 30 days).Troponin levels needed to be monitored in order to MINS diagnose and high sensitive cardiac troponin T assays are currently the most frequently used. Methods: Patients with high cardiovascular risk undergoing major non-cardiac surgery will be selected from the daily surgical program during a two years period Three determinations of hs-cTnT for each patient will be obtained. The proportion of patients with MINS and pre- and post-operative thresholds of hs-cTnT that would be prognostically relevant will be determined. The cost-effectiveness analysis of hs-cTnT monitoring compared with usual care will be undertaken. Finally using computed tomography angiography (CTA) and cardiac magnetic resonance imaging (MRI) pathophysiology of MINS will be determined, whether is due to plaque rupture, supply-demand mismatch, non-ischemic cardiac cause or non-cardiac cause. Discussion: The study will evaluate the feasibility and impact of implementing the hs-cTnT monitoring program in the Hospital de la Santa Creu i Sant Pau of Barcelona, as well as its cost-effectiveness. Moreover, this is the first study which will determine pre and postoperative thresholds of hs-cTnT and with minimally invasive diagnostic tools will evaluate potential mechanisms involved in perioperative ischemic events.
Study with food supplement to assess the eficacy of pollen extract on Urinary Incontinence
A Single arm, Multicenter, International Trial of Tisotumab Vedotin (HuMax®-TF-ADC) in Previously Treated, Recurrent or Metastatic Cervical Cancer.
In the POWDER 1 study, paroxysmal atrial fibrillation (AF) patients undergoing conventional contact force (CF)-guided PVI were investigated. Patients were randomized between continuing previously ineffective antiarrhythmic drug therapy (ADT) or stopping ADT at the end of the blanking period. This trial, showed an added value of ADT after ablation (in support of 'hybrid rhythm control' as an alternative treatment strategy for AF in some patients). In the POWDER 2 trial, an analogue study in persistent AF patients will be performed. All patients will undergo ablation index (AI)- and IL distance (ILD)-guided PVI (just like in VISTAX trial) and continue previously ineffective ADT during the blanking period. 'PVI only' was chosen as the ablation strategy according to the STAR AF trial findings.
This clinical study was designed to evaluate the pharmacokinetics, safety and efficacy of ligelizumab in children from 12 to < 18 years of age, with chronic spontaneous urticaria (CSU). The participants were treated with ligelizumab as an add-on therapy to approved doses of H1 antihistamines (H1AH) following the guideline on treatment of CSU.
This observational study is designed to more specifically describe the burden of the disease and the use of healthcare resources of subjects with eosinophilic COPD that may be eligible in the future for a biologic treatment. Subjects who attend a routine follow-up visit and fulfill the inclusion/exclusion criteria defined provide a signed informed consent will be invited by the investigator to participate in this study. Subjects will be recruited in hospital Pulmonology Services across Spain. It is planned to include approximately 20 centers. To select the final participating centers, a feasibility study has been carried out in approximately 50 potential participating centers. It has been estimated that each investigator will include 18 subjects during the 4-month inclusion period. Total 354 subjects will be required: 250 subjects with an eosinophil level >=150 cells per microliter and 104 subjects with an eosinophil level <150 cells per microliter. The study inclusion period will be 4 months (expected to be from November 2017 to March 2018) and the retrospective data collection period will be 12 months prior to the inclusion visit.
Evaluation of colonoscopy with a specific device for the detection of adenomas: Multicenter, prospective and randomized study
Objective: The aim of this project is to evaluate how intra-abdominal pressure paired coupled with different ventilatory positive end-expiratory pressure levels affects the transpulmonary driving pressure during pneumoperiteneum insufflation for laparoscopic surgery. Methodology: Patients undergoing laparoscopic surgery will be included. The study will investigate the relationship between intra-abdominal pressure (IAP) and transpulmonary driving pressure (TpDp) and the effect of titration of PEEP on their relationship. At three different levels of intra-abdominal pressure, the respiratory driving pressure (RDp) and TpDp in each subject will be measured in each subject. The same subject will undergo two different ventilation strategies. Demographic data (height, weight, body mass index and sex), ASA physical status (surgical risk classification of the American Society of Anesthesiology), number of previous abdominal surgeries, number of previous pregnancies, and respiratory comorbidities will be collected. Respiratory pressures and mechanics will be recorded at each level of intra-abdominal pressure (IAP) during each ventilatory strategy. The variables recorded will include: airway pressures (Plateau pressure Pplat, Peak pressure, Ppeak), the final esophageal pressure of inspiration and expiration and pulmonary stress index. Mixed linear regression will be used to evaluate the relationship between different PEEP levels, IAP and TpDp by adjusting for known confounders and adding individuals as a random factor. Likewise, an analysis using a mixed linear regression model with the pulmonary stress index as a function of the intra-abdominal pressure, the ventilation regime, and a specific random intercept term for each subject will be performed.
Prospective, multicenter, observational, national study (EPA-SP) that aims to describe the survival and the quality of life, the clinical management strategies and the prognostic factors for survival related to the patient, in a prospective cohort of patients over 60 with AML diagnosis in Spain and treated outside of clinical trials; that is, under conditions of standard clinical practice. The study will last 24 months in total from the inclusion of the first patient until the end of the last patient's follow-up
The investigators propose to perform a randomized clinical trial comparing prasugrel vs. ticagrelor in 60 patients with ST elevation acute myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention. The principal objective of the study would be analyzing the difference in myocardial infarction size measured by cardiac magnetic resonance at 6 months
