Clinical trials

LiverSeek is a fully automated, passive case-finding programme for advanced liver fibrosis associated with metabolic dysfunction-associated steatotic liver disease (MASLD) in primary care. The programme operates through the Laboratory Information System (LIS; Modulab/Biwer Analytics) of the Clinical Biochemistry Laboratory at Hospital General Universitario Gregorio Marañón (HGUGM), covering approximately 350,000 inhabitants across 11 peri-urban primary care centres affiliated to SERMAS (Servicio Madrileño de Salud) in Madrid, Spain. When a high-risk patient (age 50-75 years with ≥1 of: ALT above ULN + HbA1c ≥6.5%; ALT above ULN + BMI \>30; BMI \>30 + HbA1c ≥6.5%) undergoes a routine blood test in primary care, the LIS automatically calculates FIB-4. If FIB-4 \>1.30, the system reflexively orders ELF and MASEF from the same serum sample, without any action required from the primary care clinician. Patients with a positive second-step NIT (ELF ≥9.8 or MASEF ≥0.33) receive an automatic alert directing them to the Hepatology Advanced Practice Nurse for VCTE (FibroScan) and clinical evaluation. The primary objective is to evaluate the prevalence of hepatic fibrosis in the high-risk population using this single-step automated strategy. Secondary objectives include head-to-head diagnostic comparison of FIB-4+ELF vs FIB-4+MASEF vs FIB-4+FAST for histologically-confirmed endpoints (significant fibrosis ≥F2, advanced fibrosis ≥F3, at-risk MASH), evaluation of the Liver Risk Score, and a health-economic analysis. A sub-study evaluates a nurse-led structured lifestyle intervention in NIT-positive patients.

study with arbaclofen (4 weeks of titration and then 6 weeks of active/stable treatment). The effects of arbaclofen on target EEG and ERG metrics will be associated with the clinical response in measures of social and general function, adaptive behaviour, social anxiety, sensory behaviours, global functioning, and quality of life in Children and Adolescents with Autism Spectrum Disorders

Previous data from our group showed reduced BMPR2 isoform A in pulmonary hypertension associated with left heart disease (PH-LHD) of valvular origin. Focusing on dysregulation of the BMPR2-activin pathway, a key regulator of vascular homeostasis, this project uses a multimodal approach combining molecular biology, advanced cardiac imaging, and histology. Its aim is to determine the role of the BMPR2-activin pathway in the development and regression of PH-LHD. We will conduct a prospective observational study with 1-year follow-up in 150 heart failure patients of different etiologies undergoing hemodynamic assessment. Clinical parameters, biomarkers, molecular profiles, and hemodynamic/echocardiographic variables will be analyzed. A nested substudy in 40 heart transplant candidates will include thoracic CT for vascular morphometric analysis and histological correlation in explanted hearts versus healthy controls. We will also assess reversibility of vascular remodeling one year after transplantation. Results may redefine PH-LHD classification, enable phenotypic precision-medicine models, guide targeted therapies such as activin inhibitors, and refine transplant criteria in combined pulmonary hypertension.

The ColchiRen study is a phase 3, controlled, prospective, randomized, double-blind, and multicenter clinical trial. Its main objective is to demonstrate the benefit of low-dose colchicine treatment in secondary prevention of cardiovascular events in patients with moderate CKD. As a secondary objective, it aims to explore the potential beneficial anti-inflammatory effect on the progression of CKD.

The investigators developed a GMP protocol to isolate Treg cells from thymic tissue (thyTreg). The thyTreg cells are being evaluated in a Phase I/II clinical trial to evaluate the safety and efficacy of the adoptive transfer of autologous thyTreg to prevent rejection in heart transplant children (NCT04924491), with preliminary results indicating the feasibility and safety of the therapy. In addition, thyTreg cells have shown low immunogenicity in the pre-clinical setting, indicating that allogeneic use of these thyTreg cells (allo-thyTreg) would have a low risk of adverse effects. These thyTreg cells could inhibit an excessive inflammation in SARS-CoV-2 infection, or ameliorate the immunological affection underlying Acute respiratory distress syndrome, improving life-threatening manifestations, restoring immune balance, and protecting affected tissues. This clinical trial is an open-label Sequential Parallel Group Phase I/II study to evaluate the safety and efficacy of allogeneic thymus derived Tregs (thyTreg) (thyTreg) in controlling the immune dysregulation associated with SARS-CoV-2 infection and/or Acute Respiratory Distress Syndrome.
