Clinical trial of tamibarotene in patients with Autosomal Dominant Polycystic Kidney Disease
In this observational, retrospective study we will primarily aim at evaluating the independent role of baseline clinical and laboratory parameters, including TKV, in the prediction of long term chronic GFR decline and other clinical outcomes and, secondarily, the relationships between GFR and TKV changes over time, in a cohort of ADPKD patients with Stage IV CKD on chronic treatment with octreotide LAR and routinely monitored with serial GFR, TKV and clinical evaluations, at the outpatient clinic of the Nephrology Unit of the Azienda Socio-Sanitaria Territoriale Papa Giovanni XXIII, Bergamo, Italy.
Individuals with a diagnosis of autosomal dominant polycystic kidney disease (ADPKD) often have a family history of the condition although up to 10-15% of cases are sporadic mutations. The investigators recently conducted an analysis of the investigators clinic population to determine percentages of individuals who have undergone kidney imaging and genetic testing and determined total numbers of patients eligible for tolvaptan and those currently active on tolvaptan. The study team found large racial discrepancies in usage of tolvaptan and found that more patients are eligible for tolvaptan than are currently taking the medication. Reasons for this are often due to patient perception about the medication rather than treatment failure. There is a strong medical need to understand reasons for underuse of this critical medication in this population. Among those with genetic testing, the study team found large disparities in ethnic background between individuals offered genetic testing who accept versus decline testing. The study team also found that those who choose to pursue genetic testing are more likely to have no family history of the condition, presumably because the diagnosis is more "surprising" to them and thus desire for verification by genetic testing, if possible, is greater. However, it is known that genetic testing can be an important component of understanding of disease biology in all patients with ADPKD, while also providing important clinical information in some cases as individuals prepare for living donor transplantation or family planning. The investigators seek to understand barriers to use of tolvaptan and genetic testing among individuals in the clinic population and their relatives across a wide range of racial and ethnic backgrounds. The investigators hypothesize that anxiety about genetic conditions in particular is a barrier to accepting testing. The investigators seek to understand the mental health aspects of the diagnosis of ADPKD. They will also evaluate changes in symptoms compared to pre-treatment after initiation of tolvaptan in eligible individuals using qualitative techniques. In so doing, the study team hope to improve care for current patients and also to expand the pool of the clinic population to include newly diagnosed family members ideally at early stages of disease.
The goal of this National Registry is to is to collect information from patients with rare kidney diseases, so that it that can be used for research. The purpose of this research is to: - Develop Clinical Guidelines for specific rare kidney diseases. These are written recommendations on how to diagnose and treat a medical condition. - Audit treatments and outcomes. An audit makes checks to see if what should be done is being done and asks if it could be done better. - Further the development of future treatments. Participants will be invited to participate on clinical trials and other studies. The registry has the capacity to feedback relevant information to patients and in conjunction with Patient Knows Best (Home - Patients Know Best), allows patients to provide information themselves, including their own reported quality of life and outcome measures.
This project aims to identify, through RNA-Seq technology, the genetic alterations underlying undiagnosed rare diseases in pediatric and adult patients with early onset and with negative WES. - Objective 1: Set up and validate techniques. Set-up and validation of the transcriptome analysis protocol in healthy subjects and in patients with known splicing alterations and/or altered RNA expression. - Objective 2: Diagnostic phase. Study of splicing alterations and RNA levels in cultured fibroblasts obtained from skin biopsies of patients with rare genetic diseases and negative exome. Exploratory goals - Compare the RNA expression profile obtained from skin biopsy-derived fibroblasts with the RNA expression profile from blood. The most relevant results will be validated in qRT-PCR. - To analyze the transcriptional and protein profile heterogeneity in skin-derived fibroblasts in enrolled subjects. To explore the effects of genetic (from WES) and transcriptional (from RNA-seq) alterations in participants' plasma and serum. Healthy controls Five healthy subjects will be recruited from the staff of the Mario Negri Institute for Pharmacological Research. The coded samples will be used to set up the method of isolation and culture of skin fibroblasts and RNA-Seq. Validation group For the set-up and validation of the skin fibroblast isolation and RNA-Seq procedure, ten adult patients with known diagnosis and with alterations in RNA levels and/or splicing will be recruited as positive controls. Patients who meet the requirements described above will be contacted by the doctors of the Daccò Center for an interview explaining the project. Those who agree to participate in the study will be asked to sign the informed consent before proceeding with the experimental part. "Discovery/Exploration" group The exploration cohort will be composed of 30 symptomatic undiagnosed patients with suspected genetic disease (children and adults with infantile onset) belonging to the Clinical Center of the Mario Negri Institute for Pharmacological Research and for whom WES investigations did not reveal causative genetic alterations.
Primary Objectives - To assess the safety and tolerability of RGLS8429 - To assess the impact of RGLS8429 on ADPKD biomarkers Secondary Objectives - To assess the impact of RGLS8429 on height-adjusted total kidney volume (htTKV) - To characterize the pharmacokinetic (PK) properties of RGLS8429 - To assess the impact of RGLS8429 on renal function
The investigator proposes a pilot randomized clinical trial to determine the safety and tolerability of empagliflozin in ADPKD patients. To achieve this, the investigator will conduct a 12-month parallel-group, randomized, double-blind, placebo-controlled trial in 50 ADPKD patients with an eGFR 30-90 mL/min/1.73m2.
Patients with large hepatic cysts (> 5cm) may develop symptoms. These can be captured with the polycystic liver disease questionnaire (PLD-Q). Treatment of large hepatic cysts consists of aspiration sclerotherapy or laparoscopic fenestration. The safety and efficacy of both procedures has been explored in two recent systematic reviews yet no evident conclusion regarding superiority of either procedure could be drawn. The main objective of the ATLAS trial is to compare laparoscopic fenestration and aspiration sclerotherapy in patients with large symptomatic hepatic cysts on patient-reported outcomes.
Multicenter trial on the effect of the GnRH analogue leuprorelin on the growth of total liver volume in pre-menopausal women with very severe polycystic liver disease who, despite available therapy, experience growth and are heading for liver transplantation.
