About this study

Official title: Changes of microRNA Expression in Obstructive and Neurogenic Bladder Dysfunction Reveal Common Signalling Pathways Relevant for Disease Progression and Recovery

Patients with obstructive or neurogenic lower urinary tract disease will be invited to participate. Upon agreement they will undergo an assessment of bladder function (questionnaires) and bladder biopsies at 2 time-points. Bladder biopsies will be evaluated for molecular changes in the laboratory and compared to the functional findings.By uncovering the molecular similarities and differences between BLUTD and NLUTD, the investigators will elucidate some of the causative factors in the development of these disorders and highlight the impact of myogenic and neurogenic components postulated to be involved. The project involves close collaboration between clinical and basic research.

Read the detailed description

Lower urinary tract dysfunction (LUTD) has multiple causes including bladder outlet obstruction (BOO) as a result of benign prostatic hyperplasia (BPH) and neurological diseases including spinal cord injury (SCI). Manifestations of LUTD include storage symptoms such as increased daytime frequency, nocturia, urgency and urinary incontinence and voiding symptoms such as slow stream, hesitancy and incomplete emptying. The consequences of both BOO-induced (BLUTD) and neurogenic LUTD (NLUTD), leading to functional entities including the low compliance high pressure bladder as well as the acontractile high volume low pressure bladder, are believed to share some pathogenetic mechanisms.

In a previous project, the investigators have established micro ribonucleic acid (miRNA) and messenger ribonucleic acid (mRNA) expression profiles of several urodynamically defined states of BLUTD. In this follow-up project, the investigators propose to extend these studies, undertaking a comparative miRNA and RNA profiling of BLUTD and NLUTD, and investigate the dynamic alteration of microRNA expression in different functional manifestations of disease. The investigators propose to validate primary gene targets of miRNAs differentially expressed in urodynamically defined states of BLUTD and identify signaling pathways, activated during the progression from hypertrophy to decompensation. Monitoring the reversal of changes in miRNA expression after relief of obstruction and restoration of normal bladder function will help delineate the key BOO-induced miRNAs with regulatory potential. Similarly, the dynamics of miRNA alteration, observed in SCI patients during the development and management of NLUTD should reveal the role of miRNA in gene expression regulation during neurogenic-induced organ remodelling.

By uncovering the molecular similarities and differences between BLUTD and NLUTD, the investigators will elucidate some of the causative factors in the development of these disorders and highlight the impact of myogenic and neurogenic components postulated to be involved. The project involves close collaboration between clinical and basic research, and combines the analysis of human biopsy material with in vitro cell-based assays, creating a comprehensive platform for the dissection of molecular mechanisms of LUTD. This project will keep the momentum of the investigators' previous research and contribute to the basic and applied studies into bladder remodeling. It is a logical continuation of their on-going studies of the role of miRNAs in LUT disorders but represents a novel direction of research and has high diagnostic and therapeutic potential.

Questions about this trial

What is this clinical trial studying?

An observational study of Disorder of the Lower Urinary Tract, run by Insel Gruppe AG, University Hospital Bern at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Establishment of mRNA targets and pathways defining a disease state and/or potentially amendable to pharmacological evaluation. (time frame: 8 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Apr 2021.
