Clinical trials

The study aims to investigate, through the International Prostatic Symptoms Score (IPSS) questionnaire, the non-inferiority of the therapy with the alpha-blockers+Serenoa repens combination compared to the alpha-blockers+antimuscarinic combination on storage lower urinary tract syndrome (LUTS) in patients with moderate-severe symptomatic benign prostatic hyperplasia (BPH).

The study aims to collect clinical data and pseudonymized CT images of patients undergoing TEVAR in order to create an anatomical digital twin capable of simulating procedural outcomes and training machine learning (ML) algorithms. This approach will support predictive models that may assist physicians in selecting the optimal medical device, improving pre-TEVAR planning, and predicting post-TEVAR complications.

The main objective of the study is to assess whether a dietary regimen based on the principles of the FODMAP diet, compared with the current treatment programme which does not include specific dietary recommendations, can improve pain symptoms in patients with symptomatic endometriosis and intestinal symptoms (i.e. bloating, nausea, constipation, diarrhoea and vomiting) attributable to irritable bowel syndrome, compared with a control group

The goal of this clinical trial is to learn whether extracellular vesicles (EVs) in the blood can be used as biomarkers to predict chemotherapy-induced peripheral neuropathy (CIPN) in adult cancer patients receiving chemotherapy with taxanes, platinum compounds, or antimitotic drugs. The main questions the study aims to answer are whether blood levels of EVs change in patients who develop CIPN during and after chemotherapy and whether specific features of EVs, including lipids and microRNAs, are associated with the development and severity of CIPN. Participants will be followed from before the start of chemotherapy until six months after treatment ends to evaluate how changes in EVs relate to nerve damage caused by chemotherapy. During the study, participants will provide blood samples before chemotherapy, at the end of treatment, and six months later for measurement and molecular analysis of EVs, will complete questionnaires about neuropathy symptoms, and will undergo simple, non-invasive nerve function tests using a tuning fork (diapason) and a Neuropen device. This study does not test cancer drugs; instead, it aims to identify biological markers in blood that may help predict which patients are at higher risk of developing CIPN, with the goal of improving monitoring and care during cancer treatment.

Data about efficacy and safety of daratumumab in iTTP refractory or intolerant to standard immunosuppressive treatments are scarce. Therefore, the investigators aim at collecting evidence on a larger number of patients through a collaborative, international study.

This study aims to investigate whether genetic variation in the TNFAIP3 locus is associated with immune-mediated thrombotic thrombocytopenic purpura (iTTP), and whether such association is mediated by decreased expression of A20 (TNFAIP3). The study includes a case-control design to assess genotype-expression association and a cohort study to evaluate clinical outcomes such as disease relapse.

The goal of this clinical trial is to verify whether a cell culture system can be used to evaluate the presence of a factor capable of causing proteinuria in the serum of patients with primary podocytopathies. This system will also be used to evaluate the in vitro efficacy of a combined therapy for the treatment of this disorder. Researchers will compare samples from patients with primary podocytopathies with those obtained from healthy subjects and patients with other renal disorders. Participants will be asked to visit the clinic at regular intervals for up to 36 months, and to provide blood and urine samples (and a sample of the discarded plasmapheresis effluent in case the procedure is performed).

The aim of this observational study is to determine if and how kidney failure affects the development of protective immune responses following vaccination in patients on chronic dialysis. Researchers will compare the effectiveness of the influenza vaccine in inducing protective antibodies between hemodialysis patients and subjects without chronic kidney disease. Participants will: * Be enrolled at the time of influenza vaccination * Visit the clinic at 7, 14, 30, 60, and 120 days after vaccination * Be asked to provide relevant clinical information and a blood sample at each visit

Female subjects aged 50 years or older will be enrolled. Biometric data (measurements) of the aorta and iliac vessels, demographic data, pathophysiological history, and data relating to menarche, pregnancy/infertility, and menopause will be collected. The aortic diameter measurement protocol will follow standard clinical practice. Measurements will be performed by placing the probe on an axis perpendicular to the aortic axis, manually positioning the calipers in the antero-posterior and lateral-lateral directions, recording both the outer-to-outer (OTO) and inner-to-inner (ITI) diameters. Additionally, the presence of thrombus and/or calcifications and the outer-to-outer (OTO) measurement of the common iliac arteries will be detected. Primary objective: Definition of the ultrasound diameter of the abdominal aorta in the female population. Secondary objective: Identification of any sex-specific risk factors associated with abdominal aortic disease (aneurysm) in the female population. Secondary objective: Identification of any sex-specific risk factors associated with abdominal aortic disease (atherosclerosis) in the female population.

Cholestatic disease in adults comprises a heterogeneous group of conditions characterized by intra- or extrahepatic alterations of bile flow that can lead to fibrosis or hepatic decompensation. Due to the heterogeneity of clinical manifestation, which is sometimes very subtle, diagnosis based on clinical, histological, and radiological evaluation is often very complicated. Genetic testing can be helpful in identifying the cause of the clinical phenotype, thereby allowing for targeted follow-up adequate to the patient's specific characteristics and risk factors. Although the utility of genetic analysis has been well documented for other liver diseases or in pediatric cohorts of children with cholestatic disease, the use and benefits of genetic testing in adults with cholestatic disease are still little explored and investigated. In this context, through the use of whole-genome sequencing (WGS), the FIRST project aims to evaluate the role of rare genetic variants in the pathogenesis of cholestatic disease and the utility of WGS in defining a genetic diagnosis.

Primary sclerosing cholangitis (PSC) is a rare, progressive and often fatal disease of the intrahepatic or extrahepatic bile ducts, with an estimated prevalence in Western countries of 1/10,000. Biliary disease in PSC is represented by cholestasis, chronic inflammation of the bile ducts, the small tubes through which bile passes, progressive concentric fibrosis around the bile ducts2. This results in an obstruction to the passage of bile, which can lead to the development of cirrhosis with complications related to portal hypertension, cholangitis and often progress to bile duct cancer (cholangiocarcinoma). The only curative therapy in patients with PSC is liver transplantation, since no drug has been shown to be effective in preventing disease progression. The etiology is most likely multifactorial immune-mediated, where the onset of PSC is triggered by environmental factors in a genetically susceptible host2Genome-wide association studies (GWAS) have identified variations at the human leukocyte antigen (HLA) complex on chromosome 6 and several other loci, but these explain only a small part of the heritability of PSC. In most cases, PSC occurs in men in their 30s and 40s who have inflammatory bowel disease (IBD) suggesting a key role of altered intestinal permeability and inflammation. However, approximately 30% of patients do not present colonic inflammation, which is consistent with the heterogeneity of the disease. Preliminary data obtained in our laboratory analyzing a cohort of Italian individuals with atypical PSC (aPSC), identified a suggestive enrichment of rare variants in genes involved in cilia morphogenesis (CEP120 and AHI1). These data are consistent with previous findings, showing the correlation between gene variants involved in ciliopathies, including the DCDC26 gene, and chronic cholestatic disorders that can mimic PSC. Primary cilia are organelles present on the outer membrane of ductal cells, called cholangiocytes. These organelles function as antennas that detect stimuli from bile and transmit information to cells by regulating various signaling pathways involved in secretion, proliferation and apoptosis. Therefore, the alteration of primary cilia plays an important role in the de-differentiation of cholangiocytes and therefore in the development of cholangiopathies, in the invasion of inflammatory cells and in the fibrotic process. However, to date little is known about the contribution of genetic variants to the severity and progression of PSC, perhaps also due to the lack of a reliable model of bile duct. Recently, three-dimensional cell cultures, called organoids, have been proposed as a revolutionary tool in the field of cell biology, as they are able to mimic the corresponding organ in vivo.Organoids can be derived from either induced pluripotent stem cells (iPSCs) or tissue-resident adult stem cells. Compared to conventional 2D cultures and animal models, organoids allow to reproduce the genetic background of the patient in the model, recapitulating in vitro structures and functions similar to in vivo tissues. For this reason, organoids have been exploited in different applications, including drug discovery and testing, precision medicine and cell therapy 9311. However, organoids still show several limitations to model liver diseases. Indeed, they are only able to recapitulate the hepatic epithelial component, cholangiocytes and/or hepatocytes and above all they lack the 3D hepatic microenvironment, such as stromal and immune cells, which play an important role in the pathogenesis of several liver diseases. The present study is part of a project funded by the Regional Foundation for Biomedical Research (FRRB) whose general objective is to generate three-dimensional models of primary sclerosing cholangitis (PSC), called assemblyloids, and to study the cellular and molecular mechanisms through which genetic variants associated with genes involved in ciliopathies accelerate the progression of PSC. Our hypothesis is that the loss of function of cilia in cholangiocytes may represent a link between cellular senescence, development of inflammation, fibrosis and finally liver cancer. The variants related to ciliopathies could lead to an incomplete maturation of cholangiocytes with consequent malfunction that can therefore lead to a chronic inflammation of ductal cells and therefore to a persistent and uncontrolled activation of stromal cells and infiltration of immune cells. Furthermore, the generation of assemblyloids capable of reproducing native tissue as faithfully as possible will provide a new in vitro model for testing new pharmacological approaches aimed at correcting genetic mutations for improved precision medicine.

Nonalcoholic fatty liver disease (NAFLD) is globally the leading cause of liver disease and frequently progresses to cirrhosis and liver cancer. The identification of effective drugs is the main unmet clinical need. Changes in liver histones methylation accompanies the development and progression of NAFLD. Our preliminary data demonstrate that inactivation of the methyltransferases SUV420H1/2 in hepatocytes protects mice against NAFLD. In this project we propose to examine the relevance of these findings by evaluating the impact of genetic deletion of hepatic SUV420H1/2 in mice fed a steatogenic diet. To further evaluate the potential for clinical translation of these results, we will next 1) evaluate the expression of SUV420H1/2 in human liver transcriptomic data and 2) analyze the impact of genetic variations on disease outcomes in population-based cohorts; 3) test an innovative therapeutic approach based on hepatocyte-targeted antisense oligonucleotides downregulating SUV420H1/2 in human liver organoids/assembloids.

Intraluminal thrombosis (ILT) is a significant but underexplored complication in aortic interventions. It is defined as the formation of thrombosis, partially or totally obstructing the lumen, in the surgically treated, stented, or native aorta. In cases of Frozen Elephant Trunk interventions for which are performed regulary for type A dissections, or pathologies such as penetrating aorting ulcers or aneurysm of the distal arch or proximal descending, an ILT can occur early in the postoperative traject and have severe consequences. A recent systematic review and meta-analysis from our group (abstract attached as Annex 1; manuscript pending) analyzed data from 825 patients. and estimated a pooled incidence of ILT of 8.6% \[95% CI: 5.7-12.9\]. The included studies reported ILT rates ranging from 6.2% to 16.8% (1-4). Patients with ILT had significantly higher risks of dialysis (43% vs. 16%) and mortality (25% vs. 8%). Risk factors included female gender, older age, and concomitant aortic valve replacement. Despite these findings, the underlying pathophysiology and management strategies for ILT in FET remain poorly defined Intraluminal thrombosis (ILT) is a recognized but poorly studied complication following endovascular thoracic aortic repair (TEVAR). Case reports have described its occurrence, particularly in patients with blunt aortic trauma (5-14), and one study suggested a higher risk of intraluminal narrowing among female patients, associated with increased reoperation rates (15). However, no reliable data exist regarding the overall incidence, risk factors, or clinical outcomes of ILT following TEVAR. A recent systematic review conducted by our group (abstract attached as Annex 2; manuscript pending) identified 10 case reports and three retrospective studies reporting highly variable ILT rates (5-14, 16-18). A study, focusing on blunt aortic trauma patients, found an ILT incidence of 20.6% in a cohort of 34 patients, while another study observed 2 cases in 97 patients (2.06%), and a third study reported 0 cases in 11 patients (0%). The lack of consistent epidemiological data highlights the necessity of a multicenter cohort study to establish a reliable incidence estimate and investigate potential risk factors and clinical outcomes. This study aims to fill the knowledge gap through a multicenter analysis involving patients treated with FET and TEVAR. By identifying risk factors for ILT, describing related outcomes, and evaluating management strategies, the ultimate goal is to improve clinical care and outcomes for patients undergoing these procedures.

The study aims to compare the percentage of women with endometriosis who undergo PMA after medical vs surgical treatment and to describe conception patterns, pregnancy rates, and number of live vessels in women seeking offspring with endometriosis.

Idiopathic normal pressure hydrocephalus (iNPH) is a neurological condition that can cause walking difficulties, cognitive impairment, and urinary incontinence. Although iNPH can be treated with cerebrospinal fluid (CSF) shunt surgery, diagnosis is often challenging because its symptoms and brain imaging findings may overlap with those of other neurodegenerative disorders, such as Alzheimer's disease or vascular parkinsonism. As a result, some patients may experience delayed diagnosis or may not be referred for potentially beneficial surgical treatment. This observational study aims to evaluate whether combining different types of clinical information can improve the diagnosis of iNPH and help identify patients who are more likely to benefit from surgery. The study integrates cognitive testing, motor performance assessment, CSF biomarker analysis, and brain magnetic resonance imaging. Patients aged over 60 years with suspected iNPH who are evaluated within a standardized diagnostic care pathway will be included. Cognitive and motor performance will be assessed before and after a cerebrospinal fluid tap test, which is part of routine clinical practice. Results will be compared between patients who receive a confirmed diagnosis of iNPH and undergo CSF shunt surgery and patients who receive an alternative diagnosis and do not undergo surgical treatment. The results of this study may help improve diagnostic accuracy, reduce false-negative test results, and support better clinical decision-making in patients with suspected idiopathic normal pressure hydrocephalus.

Study Title: EIT-Guided Lung Recruitment Maneuvers in Pediatric ARDS: Effects on Ventilation Distribution and Respiratory Mechanics Study Objective: The primary goal of this clinical trial is to determine whether lung recruitment maneuvers guided by Electrical Impedance Tomography (EIT) result in a more homogeneous ventilation distribution and less injurious ventilation in children with pediatric Acute Respiratory Distress Syndrome (pARDS). The study will assess changes in intrapulmonary gas distribution and respiratory mechanics during recruitment maneuvers using both EIT and partitioned respiratory mechanics. This is a prospective cohort study involving children diagnosed with pARDS. Eligible participants will be consecutively enrolled over time and will undergo a standardized series of staircase lung recruitment maneuvers under continuous EIT monitoring. The final mechanical ventilation (MV) settings will be individualized and titrated based on the EIT-derived response to recruitment. Main Research Questions: How can lung recruitment maneuvers be performed safely in children with pARDS? How can we monitor the physiological effects of recruitment on respiratory mechanics? How does recruitment influence the distribution of ventilation within the lungs? Eligible participants will undergo a series of staircase lung recruitment maneuvers under continuous EIT monitoring. The final mechanical ventilation (MV) settings will be titrated and individualized based on the EIT-derived response to recruitment.

The goal of this observational study is to learn how endothelial colony-forming cells (ECFCs) behave in people with von Willebrand disease (VWD), acquired von Willebrand syndrome (AVWS), and in healthy individuals.

Pharmacological, single-center, non-profit observational study. The present study is part of a cooperation project between the SC Gastroenterology and Hepatology, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico (Milan, Italy), the University of Milan, the University of Parma and Rome Tor Vergata, funded under the call for Research Projects of Significant National Interest - 2022 PNRR Call (Prot. P2022WEXP2). Hepatitis D virus (HDV) is a defective RNA virus, which requires the presence of hepatitis B virus (HBV) to infect liver cells and propagate. To date, the mechanisms underlying the accelerated disease progression in the natural history of Delta hepatitis are poorly understood, as is the course of the HDV-specific immune response (CD4 and CD8 T cells). As in chronic HBV and HCV infections, the outcome of chronic HDV infection appears to be dictated primarily by the host immune response, which represents a key determinant for virus control or persistence. For HBV/HDV coinfection, the role of T cells has not been well defined, as suitable animal models are lacking and so far few HDV-specific T cell epitopes have been precisely mapped, mainly limited to HLA-B alleles. The study is divided into two substudies (cross-sectional and longitudinal). The primary objective of the cross-sectional study is to calculate the prevalence of HDV-specific T responses in patients with chronic HBV-HDV infection naïve to treatment with Bulevirtide. The primary objective of the longitudinal study is the change in the prevalence of HDV-specific T responses in patients with chronic HBV-HDV infection during treatment with Bulevirtide compared to baseline (pre-treatment).

Prospective, non-pharmacological, single-center, non-profit observational study. The study design allows longitudinal evaluation of the immune response during the natural history of the infection and/or treatment, correlating the data with the outcome of the disease and antiviral therapies, which will be collected as study variables from the source documents. The study population will be patients suffering from chronic HBV infection with or without HBV-HDV co-infection followed at the Division of Gastroenterology and Hepatology of Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico. The present study is part of an international cooperation project between the Division of Gastroenterology and Hepatology, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico (Milan, Italy) and the Duke-NUS Medical School, Singapore, financed by a grant (project MAECI-2023-23683653) and divided into two specific Work Packages: * WP 1 Milan team (WP1.1 - Clinical and virological phenotyping of CHB and CHD patients; WP1.2 - Clinical evaluation of rapid HBV T cell test in CHB and CHD populations) * WP 2 Singapore team (WP2.1 - Applicability of the rapid T cell assay approach; WP 2.2 - Optimization of the rapid T cell assay protocol) The primary objective of the study is to define the prevalence of specific T cell responses in patients with chronic HBV and HBV-HDV infection, through the application of a specific rapid T cell assay.

It has been estimated that alcohol causes around 40% of premature liver deaths in Europe each year, although this number is probably underestimated. Alcohol-related liver disease (ALD) is the most common cause of liver cirrhosis and liver death in Europe with a peak age of deaths occurring among individuals aged 40 to 50. Despite these findings, ALD is little studied with only 5% of all clinical trials in the field of liver disease recorded on ClinicalTrials.gov and only 5% of all publications in the same research area. Liver cancer is the second most common cause of cancer-related death (15-20% survival at 5 years) and the second most common cause of alcohol-related cancers worldwide. Like other complex diseases, ALD-HCC results from the interaction between environmental determinants and genetic variations but knowledge of gene-environment interactions is currently lacking in this area. The GENIAL project will address these needs through a comprehensive evaluation of gene-environment interactions concerning ALD-HCC.

The Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is a leading cause of chronic liver disease globally, with a prevalence exceeding 30% in the population. MASLD is strictly associated with insulin resistance and cardiometabolic conditions, and in 20-30% of cases, it can progress to steatohepatitis (MASH), which is characterized by progressive liver damage and inflammation. In patients at higher risk, the disease can lead to the onset of advanced fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). One of the main problems in the clinical management of MASLD is the absence of specific risk biomarkers and the lack of effective treatments, especially for patients with advanced-stage disease. MASLD has a well-documented and enormous genetic component, with studies having identified several common variants associated with this pathology, such as those in the PNPLA3, TM6SF2, and MBOAT7 genes. However, these variants identified so far only explain a small part of MASLD's heritability, suggesting the contribution of rare loss-of-function (LoF) variants as well. Furthermore, scientific evidence indicates that the accumulation of somatic variants, both in hepatocytes and myeloid cells, could also play a key role in MASLD progression. In particular, clonal hematopoiesis of indeterminate potential (CHIP), which is a condition characterized by the presence of hematopoietic clones with somatic mutations often associated with leukemia and cardiovascular diseases, might favor the onset of hepatocellular carcinoma. However, the evidence available to date is still limited and requires further investigation and studies on larger cohorts. The current study therefore aims to deepen this aspect through the analysis of the genetic profile using a Whole-Genome Sequencing (WGS) approach. DNA samples from peripheral blood from patients with advanced MASLD and peripheral blood DNA samples from controls presenting various associated metabolic risk factors will be sequenced. In addition, 80 liver tissue samples from patients with advanced MASLD will also be sequenced to identify specific somatic mutations. The expected results from this study include the identification of new genetic variants associated with MASLD progression, the improvement of risk stratification through the development of polygenic risk scores, and the identification of potential therapeutic targets. This study represents a fundamental step for understanding the biology of MASLD and could have important clinical implications for disease management.

The primary objective of the study is to generate and characterize three-dimensional models, called "assembloids", composed of the main liver cell populations (in particular from the co-culture of organoids with stellate cells, responsible for fibrogenesis, deriving from clinical samples). These models will be used in order to imitate the first phases of the onset of steatohepatitis, in conditions of altered lipid metabolism (induced through exposure to the main environmental determinants of this condition: excess fatty acids, fructose, cholesterol) in the presence or absence of the mutation I148M of PNPLA3. Other genetic variants will also be analyzed, such as TM6SF2, MBOAT7 and GCKR, which have previously been correlated with the development of non-alcoholic steatohepatitis. Further objectives will be: 1) identify new biomarkers of pathological activation of human stellate cells and progression of liver damage, to be subsequently validated in clinical case series for future use in clinical management for individual risk stratification; 2) study the epigenetic factors that underlie the onset of non-alcoholic steatohepatitis and its progression to fibrosis, cirrhosis and HCC; 3) evaluate the impact of antisense oligonucleotides directed against PNPLA3 on the severity of the "steatohepatitic" phenotype (lipid accumulation, lipotoxicity and inflammation and fibrogenesis) in assembloids

NAFLD is most frequently linked to excess adiposity, insulin resistance and cardiometabolic risk factors, it has become the leading cause of liver disease worldwide, and is associated with increased mortality due to multiple causes. HFC has a strong genetic component and the investigators recently showed that it plays a causal role in determining progressive liver disease and insulin resistance. The genetic risk score predicting liver fat content (HFC-GRS) improves the stratification of liver related events, and the investigators have preliminary data on new common and rare variants that contribute to NAFLD susceptibility, and on a new non-invasive circulating biomarker associated with hepatic fat and lipotoxicity (Interleukin-32). However, no data are yet available on the causal role of hepatic fat on the procoagulant state associated with NAFLD, which could participate to liver damage and is a causal factor in atherothrombotic complications. The aim of the study is to examine the potential application of a precision medicine approach to the improvement of stratification of the risk of liver-related and cardiovascular thrombotic complications of hepatic fat accumulation (HFC) and non-alcoholic fatty liver disease (NAFLD), with a special focus on the role of procoagulant imbalance in mediating the at-risk phenotypes.

Hepatocellular carcinoma (HCC) is the fifth most common solid cancer and the second cause of cancer-related mortality worldwide. Nonalcoholic fatty liver disease (NAFLD), that is hepatic accumulation of fat in excess of 5% not explained by at risk alcohol intake, is projected to become the leading cause of HCC in Western countries within 2025.NAFLD is most frequently caused by insulin resistance due to unhealthy lifestyle. Due to the epidemics of obesity and type 2 diabetes, NAFLD now affects one in three individuals worldwide. NAFLD-HCC frequently develops without overt cirrhosis suggesting that steatosis directly promotes hepatic carcinogenesis.

Prostate biopsy is the key examination for the histological diagnosis of prostate cancer. This procedure can be performed via the transrectal (TR) or transperineal (TP) approach. Current Guidelines recommend the transperineal route because it is associated with fewer infectious complications compared to the transrectal approach. However, when the same type of anesthesia is used, the transperineal approach is more painful. Several strategies have been developed to improve pain management during TR biopsy. Some studies have shown that allowing patients to listen to music during the procedure can reduce perceived pain and stress. However, this effect has never been investigated in TP biopsies, which are now the gold standard and generally more painful than TR biopsies. Primary Objective: To evaluate the reduction in pain levels in patients undergoing transperineal prostate biopsy with the aid of music compared to patients undergoing the same procedure without music. Secondary Objectives: To evaluate the reduction in stress levels related to the procedure in patients undergoing transperineal prostate biopsy with music compared to those without music. To evaluate the reduction in the use of painkillers and sedatives during the procedure in patients undergoing transperineal biopsy with music compared to those without. To assess pain management and procedure tolerability in both groups.
