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: Upper tract urothelial carcinoma (UTUC) is a rare tumor associated with bladder cancer in up to 50% of cases. Its incidence is rising due to improved detection and bladder cancer survival. The diagnosis of UTUC is challenging because more than 35% of the standard biopsies can result inconclusive. The grading of UTUC cells, which delivers the most important data for the choice between a kidney-sparing surgery (KSS) and a radical treatment, is upgraded in 30% of radical nephroureterectomies. The follow-up of UTUC after KSS requires an invasive procedure as a diagnostic ureteroscopy for a minimum of 5 years, and urinary cytology has low diagnostic power. Objective: The aim of the study is to evaluate the accuracy (overall and stratified for grade) of a DNA methylation urine biomarker test (Bladder EpiCheckTM) in UTUC, and to compare it with current standard (urinary cytology). The secondary objective is to show its applicability in the specific clinical scenario of UTUC surveillance after kidney-sparing surgery and related cost-effectiveness. Design, Setting, and Participants: From February 2019 to February 2021, 80 consecutive patients candidates to ureteroscopy for suspicion of primary, recurrent or metachronous UTUC in one tertiary Referral Centers (Fundaciò Puigvert) giving written informed consent will be included in the study. Intervention: Bladder urine samples (> 10 ml) will be collected for cytology and for the methylation test before cystoscopy. Prior to semirigid and flexible ureteroscopy, urine specimens from the upper urinary tract will be obtained via a ureteral catheter.
The WE-TRUST study is a multi-center randomized clinical trial to assess the impact of a Direct to Angio Suite (DTAS) workflow on stroke patient outcomes.
A perianal fistula is an abnormal passageway that develops between the rectum and the skin near the anus. The fistula is considered complex if it branches into several openings or an abscess is also present. The main aim of this study is to learn if complex perianal fistulas in children and teenagers close after treatment with darvadstrocel. 2 to 3 weeks before treatment with darvadstrocel, each participant will have surgery to clean the fistula and to drain any abscesses. On the day of treatment, each participant will have the fistula cleaned and will receive an injection of darvadstrocel near the fistula, under anesthetic. For up to 1 year after treatment, participants will regularly visit the clinic for follow-up. The fistula will be examined and any side effects from the treatment will be recorded. Participants will have an MRI at one clinic visit (about 24 weeks after treatment).
Frailty is very frequent among patients waiting for a kidney transplantation (KT). Frailty and poor fitness powerfully predict mortality, kidney graft survival, and healthcare utilization after KT. Frailty in patients with chronic kidney disease (CKD) displays a constellation of features that characterize a special population. Intervention is essential to improve quality of life for frail CKD patients, regardless of their age. A pre-transplant intervention including physical therapy, nutritional measures and psychological support scheduled for before the transplant may improve patient retention and compliance, better mitigate the effects of frailty and poor fitness after KT, and improve main outcomes in frail CKD patients. The main objective is to assess effectiveness, feasibility and safety of a prehabilitation program (exercise, nutritional plans, psychological advice) in frail and non-frail KT candidates on clinical and functional outcomes after KT.
This study is a prospective, multicentre, parallel-group, active-controlled, non-inferiority study conducted in adult patients with moderate-to-severe dry eye disease (DED) related to keratitis or keratoconjunctivitis. This study is to be conducted in France, Poland and Spain. The patients will be randomised to receive Cationorm Pro® or the reference treatment, VISMED® (ratio 1:1) in an investigator-masked fashion
Objective: To test the preventive effect of the placement of an onlay mesh versus the use of a fascial closure device at the umbilical trocar site closure in order to prevent incisional hernia after laparoscopic surgery. Methods: We designed a Two Center Randomized Controlled Trial were adult participants presenting for elective laparoscopic cholecystectomy, with or without an exploration of the common bile duct will be recruited, with allocation of each of them in 2 groups (prosthesis and control). Abdominal ultrasound scan focused on aponeurosis defects at the trocar sites will be performed at 12 postoperative months. An ultrasound scan will be performed to avoid underdiagnosis bias since incisional hernia is frequently under detected by clinical examination. Relevance: The prevalence of incisional hernia after laparoscopy might be as high as 30%, due to this reason is paramount to find a better closure technique. There are few studies about incisional hernia including radiological exams in order to provide the exact prevalence of this pathology, even fewer literature exists about incisional hernia after laparoscopic procedures.
This is a phase Ib/II open label study. The escalation part will characterize the safety and tolerability of JDQ443 single agent and JDQ443 in combination with the other study treatments (TNO155 and tislelizumab) in advanced solid tumor patients. After the determination of the maximum tolerated dose / recommended dose for a particular treatment arm, dose expansion will assess the anti-tumor activity and further assess the safety, tolerability, and PK/PD of each regimen at the maximum tolerated dose / recommended dose or lower dose.
Recently, a new clinical presentation called "long covid" has been reported, for patients with symptoms lasting for more than 4 weeks from the onset of the disease. Typically, the symptoms comprise dyspnea, cough, headache, arthralgia, fever, abdominal pain, asthenia and skin manifestations This project aims to evaluate the efficacy of Montelukast in improving the quality of life associated with respiratory symptoms in patients with persistent COVID-19 symptoms. The main objective is to compare the efficacy of low-dose Montelukast versus placebo to improve respiratory symptoms in patients with persistent COVID-19 symptoms.
The study's purpose its to evaluate the efficacy and safety of troriluzole as adjunctive therapy compared to placebo in subjects with Obsessive Compulsive Disorder (OCD)
The purpose of this study is to monitor short-term changes in tissue oxygen saturation and local blood flow as results of changing from supine to prone position in ARDS COVID-19 patients
