Study summary

This is a prospective, non-interventional, single arm, international multicenter study in which up to 120 adult participants with kidney failure requiring regular hemodialysis through arteriovenous (AV) access (AV fistula or graft) will be recruited and evaluated using the PatenSee system.

Data captured on the PatenSee system will be analyzed and evaluated against standard of care clinical monitoring of AV accesses.

Read the detailed description

For eligible participants, a clinical exam of the AV access ("Look, Listen, Feel") per SOC will be done by a qualified site clinician/nurse, followed by an assessment of the AV access using the PatenSee system on a weekly basis for 6 weeks, and then biweekly up to 1 year from enrollment. Additional data regarding imaging and complications of the AV access will be collected. Clinical decisions, such as referrals for further investigation and management of the AV access will be based solely on standard clinical monitoring.

Study population

Primary dialysis clinics

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Male and female adult patient aged ≥18 years old
  2. Patient has a non-reversible kidney failure that requires long-term hemodialysis
  3. Patient has a functioning AV access (AVF/G) in the upper extremity
  4. Patient is able and willing to provide consent by signing an EC/IRB approved form
  5. Patient is willing and able to follow the requirements of the study

Exclusion criteria

Exclusion Criteria:

  1. An active AV access infection
  2. An AV access condition that will likely require revision, e.g., symptomatic steal syndrome
  3. Expected to recover kidney function, receive a kidney transplant, transfer to peritoneal dialysis (PD) or transfer to non-study site during the study period.
  4. Any reason per investigator's discretion for which the patient is not suitable for the study
  5. Any medical or psychiatric illness, which in the opinion of the investigator would compromise the patient's ability to adhere to study requirements
  6. Previous participation in an interventional study within 30 days prior to study enrollment that may interfere with evaluation of the study endpoints
  7. Female patient is pregnant or breastfeeding
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Comparison of "Look" assessment with PatenSee's relevant output

    Agreement between the ability to detect AV access structure parameters by PatenSee's images and the ability to detect the same parameters by clinical monitoring

    Time frame: 6 weeks per patient

  2. Comparison of "Listen & Feel" assessments with PatenSee's relevant output

    Agreement between the PatenSee audio analysis of the AV access bruit and the sound recording of the AV access using a standard digital stethoscope measured

    Time frame: 6 weeks per patient

Secondary outcomes

  1. Functionality endpoint - Average time to conduct PatenSee scanning data capture

    Average time to conduct PatenSee scanning data capture

    Time frame: Up to 12 months

  2. Functionality endpoint - Proportion (%) of participants on whom the PatenSee was used as planned

    Proportion (%) of participants on whom the PatenSee was used as planned

    Time frame: Up to 12 months

  3. Functionality endpoint - Average number of weeks participants obtained PatenSee measurements

    Average number of weeks participants obtained PatenSee measurements

    Time frame: Up to 12 months

Other outcomes

  1. Safety Endpoints - Assessment of device related AEs

    Assessment of device related AEs

    Time frame: Up to 12 months

  2. Exploratory Endpoints - AV access data collection

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2025 (actual). Primary completion is estimated for Jun 2026, 12 months after the start.

Of 25 observational studies under Fistula, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 54. This study's planned 12 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 26, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
