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.
A high platelet reactivity in patients with severe symptomatic Aortic Stenosis (AS) selected for TAVI (Transcatheter aortic valve implantation) procedure has been demonstrated previously, and the use of double antiaggregation therapy (DAPT) with Clopidogrel and Acetylsalicylic acid (ASA) do not achieve consistent and adequate suppression of platelet reactivity. The purpose of this study is evaluate the efficacy of ticagrelor alone versus DAPT with clopidogrel and aspirin for the suppression of high platelet reactivity following TAVI.
Objectives: For major laparoscopic surgery, as with open surgery a multimodal analgesia plan can help control postoperative pain. Placing a wound catheter intraoperatively following colon surgery could optimize the control of acute pain with less consumption of opioids and few adverse effects. Methods: We conducted a prospective, randomized, study of 103 patients scheduled to undergo laparoscopic colon surgery for cancer in Galdakao-Usansolo Hospital. Patients were recruited and randomly allocated to wound catheter placement plus standard postoperative analgesia or standard postoperative analgesia alone. A physician from the acute pain management unit monitored all patients for at multiple points over the first 48 hours after surgery. The primary outcome variables were verbal numeric pain scale (NRS) scores and amount of intravenous morphine used via patient controlled infusion.
The microbiota represents the collections of microbial communities that colonize a host. In health, the microbiota protects against pathogens and maturation of the immune system. In return, the immune system determines the composition of the microbiota. Altered microbial composition (dysbiosis) has been correlated with a number of diseases in humans. The real role of the microbiota in transplant recipients is still unknown even though we suspect that it may be affected directly or indirectly by immunosuppressive drugs and antimicrobial prophylaxis taken by transplant patients, as well as by inflammatory process secondary to ischemia/reperfusion injury. A number of studies have investigated the impact of liver transplantation on the intestinal microbiota. In a recent analysis of stool flora (Microb Ecol 2013; 65: 781-791) in 12 liver transplant recipients, changes in the microbiota were correlated to post-transplant infections. The authors suggested that the shift to pathogenic strains of bacteria due to the use of prophylactic antibiotics may be contributing to post-transplant complications. In a larger study, Wu et al (Hepatobiliary Pancreat Dis Int 2012; 11: 40-50) demonstrated marked changes in the gut microbiota post-transplantation with an increase in Enterobacteriaceae and Enterococcus, and reduction in Eubacteria, Bifidobacterium and Lactobacillus species. These changes, however, resolved over time such that by 6 months, at times when bacterial prophylaxis ends and immunosuppression is reduced. A better characterization of the impact of post-transplant therapy on the human microbiota has the potential to improve our understanding of the infection process and translate into development of new therapeutic strategies. The main goal of this study is to characterize intestinal microbiota and confirm the same bacterial DNA in peripheral blood and portal lymph nodes in patients affected with end-stage chronic liver disease, and to analyze its evolution from the moment of inclusion in waiting list throughout the first year after liver transplantation. For each patient, a healthy CONTROL with a similar age (± 10 years) will be selected from the same family setting, in whom just one sample will be obtained during the enrollment phase. The second goal is to analyze the potential associations between microbiota flora and transplant outcomes during the same period.
To assess the safety and tolerability at increasing dose levels of PF-06647020 in patients with advanced solid tumors in order to determine the maximum tolerated dose and select the recommended Phase 2 dose.
Part A (Phase IIa): Primary objectives: The study part A is designed to investigate whether the use of regorafenib eye drops can help patients with neovascular (wet) Age-Related Macular Degeneration (wAMD) to see better after 4 weeks and 12 weeks after inclusion into this study. Secondary objectives: The study will also evaluate the safety and tolerability of the regorafenib eye drops. Part B (Phase IIb): Primary objectives: The study part B is designed to investigate: - how often the regorafenib eye drops need to be given per day - whether the use of regorafenib eye drops can help patients with neovascular (wet) Age-Related Macular Degeneration (wAMD) to see better after 4 weeks and 12 weeks after inclusion into this study. Secondary objectives: The study will also evaluate how the different dosings of regorafenib eye drops affect patients vision, the safety and the tolerability.
In case of PET or CT based cN1 (suspected) NSCLC, ESTS guidelines propose mediastinal staging by echo-endoscopy OR mediastinoscopy. Recent data show a sensitivity of less than 50% for echo-endoscopy to detect N2 disease in cN1 NSCLC patients, while prevalence of mediastinal nodal disease was 24% (unpublished data Aster II).2 The investigators plan to perform a prospective multicentric observational study to measure the sensitivity of mediastinal staging by video-assisted mediastinoscopy (VAM) in cN1 operable and resectable (suspected) NSCLC patients.
Within a prospective, randomised, controlled study 60, selected patients with chronic (> 6 months) stroke or traumatic brain injury will be randomised to 30 1-hour sessions of competitive versus non-competitive attentional training. Competitive training will include fifteen 1-hour sessions of standard (paper and pencil) training under competitive situations and fifteen 1-hour sessions of competitive attentional games designed for this purpose using a new virtual reality system (conventional liquid-crystal-display screen with an infrared LED array to facilitate multi-touch experience embedded in a conventional table). Progress will be evaluated by pre and post measurement of attentional neuropsychological tests, subjective reports of global attention, usability and motivational scales. Our hypothesis is that competitive training is more effective in improving attention than conventional training in the chronic phase after acquired brain injury.
The purpose of the study is to 1) define the operating characteristics of fungal biomarker assays in pediatric patients at high-risk for developing invasive candidiasis, 2) determine the change in fungal biomarker assay results in children who develop invasive candidiasis, and 3) create a biobank of blood samples from pediatric patients at high-risk for invasive candidiasis and those with invasive candidiasis for future testing of fungal biomarker assays and development of new fungal biomarker assays. The study will assemble a prospective cohort of pediatric patients at high-risk for developing invasive candidiasis. Blood samples for biomarker testing will be obtained at the time a patient has a clinical indication for blood culture attainment. Additional blood sampling will be performed on the sub-set of patients that are found to have invasive candidiasis. The sensitivity, specificity, PPV, and NPV of biomarker assays will be determined for each biomarker assay. No PHI will be stored in the database and limits on blood draws (3 ml/kg in an 8 week period) will be adhered to.
This open-label, non-randomized, prospective study will evaluate the risk of symptoms recurrence during the three years after antipsychotic discontinuation in a sample of functionally recovered first-episode patients with schizophrenia spectrum disorder.
This is a first-in-human, Phase 1, open-label, multicenter, dose-escalation study designed to evaluate the safety, tolerability, and pharmacokinetics of MOXR0916 administered intravenously in participants with locally advanced or metastatic solid tumors that have progressed after all available standard therapy or for which standard therapy has proven to be ineffective or intolerable, or is considered inappropriate. This study will consist of a screening period, an initial treatment period, a re-treatment period (for participants who discontinue MOXR0916 after demonstration of prolonged clinical benefit), and a post-treatment follow-up period. Participants will be enrolled in two stages: a dose-escalation stage and an expansion stage. The planned duration of the study is approximately 3 years.
