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.
Non-muscle invasive bladder cancer of High Grade stage T1 (HGT1), has up to 20% risk of progression to invasive disease. Because the depth of substaging seems to identify two separate groups with different progression risk (HighGradeT1a and HighGradeT1b), we design a differential treatment strategy for each group. The main hypothesis is that HighGradeT1a bladder cancer can spare a second endoscopic procedure.
This study evaluated the safety and efficacy of sebelipase alfa in a broad population of participants with lysosomal acid lipase deficiency (LAL-D).
This is a prospective, multi-center, single arm, non-randomized study to define safety and efficacy of the Veniti Vici™ Venous Stent System in relation to pre-defined Objective Performance goals. A maximum of 200 patients at up to 45 centers worldwide will be enrolled. Thirty (30) feasibility patients will be enrolled at approximately 7-10 centers and 170 pivotal patients will be enrolled at approximately 45 centers worldwide. The follow-up period is 36 months.
Introduction: Minor psychiatric disorders are important in primary care, because of its high prevalence and consumption of healthcare resources generated. Objective: Evaluate the effectiveness of rational emotive behavioral therapy (REBT), as an instrument of social work intervention to enhance changes in the parameters of quality of life, medical consultations and drug use in patients with dysthymia. Design: Multicenter, prospective, not randomized clinical trial, with intervention and control group simultaneously in urban primary care settings and 1 year of follow up. Participants: Out-patients seen in two Primary Care centers diagnosed with dysthymia according to DSM-IV classification of American Psychiatric Association. Intervention: Subjects receive up to 8 biweekly individual sessions of thirty minutes of REBT administered by the Social Worker. Variables: Demographic data, educational level, coexistence, comorbidity, quality of life assessment, severity of depression, number of visits to the General Practitioner (GP) and drug consumption: sedatives / antidepressants. Expected Results: The expected results of the intervention, estimated from previous data, are: - A decrease in attendance at medical visits per year - An improvement in perceived quality of life, measured as values of the Quality of Life (QOL) questionnaire (Baker & Intagliata) - An improvement in severity of depression, measured according to the Beck Depression Inventory. - A reduction of treatment with psychotropic drugs (sedatives and antidepressants). Potential impact expected: The investigators hope that rational emotive theory is an effective intervention method for handling minor psychiatric disorders in clinical social work.
The purpose of this study is to determine whether ThermoDox, a thermally sensitive liposomal doxorubicin, is effective in the treatment of non-resectable hepatocellular carcinoma when used in conjunction with standardized radiofrequency ablation (sRFA).
Prospective, multi-center, open-label, single-arm, Phase 3b extension study of macitentan in patients with PAH. To assess the long-term safety of macitentan in patients with pulmonary arterial hypertension (PAH) beyond treatment in the AC-055-310 study.
The purpose of this study is to compare the safety and efficacy of Lenalidomide versus Placebo maintenance following melphalan, prednisone and velcade induction therapy in newly diagnosed multiple myeloma. After the study is unblinded, subjects in treatment Arm A (Len 10 mg) will remain on study therapy at the Investigator's discretion and subjects in treatment Arm B (placebo), will be discontinued from study treatment. Subjects who discontinued from study treatment for any reason will enter the LTFU Phase.
All vascular access guidelines recommend monitoring and surveillance protocols to prevent vascular access complications in hemodialysis units. However, in the case of second generation screening techniques which determine access blood flow measurement (QA), there is a huge controversy about it´s efficiency. Although multiple observational studies find a decrease in the thrombosis rate and an increased primary assisted patency survival related to the use of these techniques, a recently published meta-analysis find contradictory results in the randomized controlled trials, affirming that the measurement of QA is useless in grafts and questionable in native arteriovenous fistulae (AVF). We have designed a multicenter, prospective, open label, controlled, randomized trial, to prove the usefulness of the QA measurement using two complementary second generation techniques, Doppler ultrasound and Transonic dilution method, compared to the classical monitoring and surveillance methods. The primary endpoint will be a reduction in the thrombosis rate with an increased assisted primary patency survival, and a cost effectiveness economic analysis. As secondary endpoints we will analyze the impact over non-assisted primary patency survival and secondary patency survival.
The VIABLE study sought to confirm the hypothesis that the combination of docetaxel with DCVAC/PCa followed by a maintenance therapy with DCVAC/PCa would improve overall survival in patients with metastatic castration-resistant prostate cancer.
The purpose of this study is to evaluate the efficacy and safety of rivaroxaban compared with placebo in the prevention of symptomatic venous thromboembolism (VTE) events and VTE-related death post-hospital discharge in high-risk, medically ill patients.
