e۰Sense® Catheter Clinical Investigation

e۰Sense® Clinical Investigation: Assessing the Performance, Safety and Usability of e۰Sense® Electronic Catheters for Performing Urodynamic Studies

This pre-market study will be conducted on consenting patients undergoing a medically prescribed, invasive, conventional urodynamics (UDS) test using the investigational device (e۰Sense® urodynamic catheters). Data pertaining to the safety, effectiveness and usability of the catheters will be collected.

Study Overview

• Status: Completed
• Conditions: Urodynamics
• Intervention / Treatment: Device: eSense 7fr Single Sensor Bladder Catheter

Detailed Description

The study will recruit and consent up to 65 subjects from up to 4 different sites (minimum 15 subjects recruited at each site) in the European Union, and the expected duration of each subject's participation is one clinic visit to receive their already requested UDS test. A follow-up call will be conducted three to five days later to collect adverse event information post-test. An interim analysis is to be performed when data from 30 patients has been completed to support the primary objective, and using the results for regulatory purposes (e.g. CE marking). However, the study enrollment continues, during the interim analysis, until 60 patients (maximum 65) have been recruited and all data collected. At the end of the study, the data will be analysed against secondary and exploratory objectives including an exploratory analysis of the primary objective on all patients.

To collect data for the study, Case Report Forms (CRF) have been developed. They will be paper based and do not include any patient identifiers except a Site Subject ID. Any document linking the Site Subject ID to subject information will be stored at the site and not shared with the sponsor. Additionally, CRF completion guidelines will be developed prior to study initiation to aid correct and consistent data collection. These guidelines will be provided to the site and site personnel will be trained prior to subject enrollment. CRFs will be treated as source data in the event that the original information is entered on the CRFs first, and no source document worksheet is utilized for that data point. Laborie will enter CRF data in to an excel database that has been developed to represent each field on the CRF. Data Management activities are conducted in accordance with Laborie's Data Management Plan, including but not limited to: source data verification (monitoring), query handling and resolution, data entry quality control and controlled database locking. Guidelines have also been created that contain detailed descriptions of each data entry point and how to enter in the database.

The data from the CRFs will be used to make the following assessments:

• The investigator will be asked to make an assessment to determine the safety and performance of the device regarding the intended use.
• A Numeric Pain Rating Scale (NPRS) will be used to assess the parameters of patient discomfort/pain, if appropriate.
• All adverse events will be recorded to assess the safety of the device.
• Subjective questionnaire completed by the user to assess ease of use, ease of insertion and removal, ease of securing the catheter, tracing stability (overall, during filling, voiding and UPP where applicable), tracing quality (overall, Pves, Pabd, Pura where applicable), channel subtraction quality, visibility on Video Urodynamics (VUDS, where applicable), catheter stiffness, sensor location, patient tolerance, and overall usability performance.
• Pre-test at various positions and resting pressures through the study
• The de-identified urodynamic data files will be collected and stored

Risks to the patient will be no greater than those of a standard Urodynamics test. Patients may experience temporary discomfort upon insertion of the catheters. Test duration may be slightly longer than a standard test while assessment of the study materials is being made, and so discomfort and inconvenience associated with an extended test duration may occur. Furthermore, bladder catheterization can increase the risk of urinary tract infection, but with no higher incidence than during standard urodynamics. No patient follow-up visit is scheduled for this study, unless deemed necessary by the physician in the event of adverse event(s).

Monitors are appointed by Laborie and are appropriately trained with scientific and/or clinical knowledge needed to monitor the trial adequately. The monitors are also thoroughly familiar with the investigational medical device under investigation, the protocol, written informed consent form (ICF), and any other written information to be provided to subjects, Laborie standard operating procedures, ISO 14155, and GCP.

The monitor conducts activities per Laborie's Monitoring Plan, including but not limited to:

• Acting as the main line of communication between the sponsor and the investigator.
• Verifying that the investigator has adequate qualifications, number of subjects, and resources and remain adequate throughout the trial period, and that facilities are adequate to safely and properly conduct the trial and remain adequate through the trial period.
• Initiating each participating sites
• Ensuring the investigational device is being used according to the protocol and instructions for use
• Verifying that the investigator and investigation site team understands and follows the approved protocol and all approved amendments (if any).
• Verifying that the investigator is familiar with the responsibilities of the principal investigator.
• Ensuring the investigator and site team are informed and knowledgeable of all relevant document updates concerning the clinical trial.
• Ensuring that the investigator receives the most up-to-date copy of the Investigator's Brochure, all documents, and all trial supplies needed to conduct the trial properly and to comply with the applicable regulatory requirements.
• Verifying that only authorized and trained site personnel are participating in the clinical trial.
• Verifying that source data and other records are accurate, complete, up to date, stored, and maintained appropriately.
• Signed and dated informed consent forms have been obtained from each subject at the point of enrolment or before any clinical-investigation-related procedures are performed.
• Verifying that CRFs and queries are complete, recorded in a timely manner, and consistent with SD.
• Verifying that appropriate corrections, additions, or deletions are made to the CRFs, dated, explained if necessary and initiated by the authorized designee. The monitor shall NOT make corrections, additions, or deletions to the CRFs.
• Ensuring all adverse events (AEs) and device deficiencies (DDs) are reported to the sponsor and all serious AEs as well as DDs that could have led to serious adverse device events are reported to the sponsor without unjustified delay.
• Verifying that subject withdrawal has been documented and that subject or site non-compliance with the requirements has been documented.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Clinician Safety and Effectiveness Rating of eSense Catheters (Per Patient)	The primary objective of the study is to gather clinical data to confirm that the updated e۰Sense® catheters are safe and effective for urodynamic use in subjects medically indicated for urodynamics testing. The primary outcome will be measured by recording the clinician safety and effectiveness rating for each subject on their CRF. The clinicians will indicate whether each of the e۰Sense® bladder and abdominal catheters are safe & effective for urodynamic use. Given the intended use of the device, and the fact that there is no single or combined objective measures generated from the UDS test that can establish the safety and effectiveness, it is justified to obtain clinicians' feedback via a binary response whether the device is safe and effective for urodynamic use.	approximately 60 minutes

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
To Report the Severe Complication-free Rate for the Updated e۰Sense Catheters.	Outcome not included in a priori interim analysis plan as per the protocol. The secondary outcome will be measured by recording the number of severe complications and serious adverse events (as defined in the protocol) for each subject on their CRF. Due to the low risk profile of UDS, the sponsor would like to report the severe complication-free rate for any severe complications associated with UDS, and therefore this secondary safety endpoint was planned. Additionally, the sponsor would like to collect and assess this information due to a lack of available published data using the e۰Sense® catheter technology.	approximately 60 minutes

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Assess User Impression Based on Subjective Measures	Outcome not included in a priori interim analysis plan as per the protocol. Assess user impressions of the updated e۰Sense® catheters compared with their experience using the existing catheters at each site, by evaluating the following subjective measures: ease of use, ease of insertion and removal, ease of securing the catheter, tracing stability, tracing quality , channel subtraction quality, visibility on VUDS (where applicable), catheter stiffness, sensor location, subject tolerance, and overall usability performance. This exploratory endpoint will be measured by collecting usability data in a questionnaire format. At the end of each clinic day a trained clinical user shall complete the questionnaire. When evaluating the usability of a device, the sponsor feels it's appropriate to use a subjective ordinal scale response while assessing human and device usability factors.	approximately 60 minutes
Asses Subjective Discomfort Levels in the Study Population	Outcome not included in a priori interim analysis plan as per the protocol. Assess subjective subject feedback regarding their discomfort and pain levels. This exploratory endpoint will be measured by collecting subject feedback regarding the level of discomfort and pain experienced during their Urodynamic test using the Numerical Pain Rating Scale (NPRS). Subjects will grade their discomfort/pain on the NPRS from 0 ("No Pain") to 10 ("Worst Pain"). Given the subject population, use of the NPRS is a validated tool in evaluating pain ratings in adults.	approximately 60 minutes
Assess Resting Pressures in the Subject Before Urodynamics	Outcome not included in a priori interim analysis plan as per the protocol. This exploratory endpoint will be measured by recording initial resting pressures (in cmH20) using the updated e۰Sense® catheters while each subject is positioned in a sitting, standing and supine position, if patient mobility allows. Resting pressures will be recorded on each subjects' CRF 1 during their urodynamics visit.	approximately 60 minutes
Assess Resting Pressure at Different Filling and Emptying Volumes	Outcome not included in a priori interim analysis plan as per the protocol. This exploratory endpoint will be measured by recording resting pressures (in cmH20) using the updated e۰Sense® catheters during various points of the UDS test as applicable (every 100 mL of filling, MCC, and post-void) at the recorded patient position (sitting, standing, or supine). Patients are to remain in the same position throughout, however supplemental positions can be used (e.g. performing provocative manoeuvres). Resting pressures and patient position will be recorded on each subjects' CRF 1 during their urodynamics visit.	approximately 60 minutes
