EndoForce Post Approval Study

January 16, 2026 updated by: Phraxis, Inc.
The goal of this observational study is to collect long-term safety and performance data for the use of the EndoForce System for connecting a hemodialysis graft to a vein in patients with End Stage Renal Disease. This is not an experimental procedure or an experimental therapy. This means that the study device has been approved by the FDA.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with end stage renal disease requiring hemodialysis

Description

Inclusion Criteria:

  • Patient is ≥18 years of age.
  • Patient requires the creation of a vascular access graft for hemodialysis, secondary to a diagnosis of ESRD.
  • Patient is able to have the vascular access ePTFE graft placed in an upper arm.
  • Patient or his/her legal guardian understands the study and is willing and able to comply with the dialysis schedule and follow-up requirements.
  • Patient or his/her legal guardian provides written informed consent.

Exclusion Criteria:

  • All contraindications for the EndoForce Connector System according to the IFU.
  • Patient is pregnant.
  • Patient is enrolled in another dialysis or vascular investigational study, without prior approval from the Sponsor.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
AVG Cumulative Patency
Time Frame: 2 years
The percentage of subjects free from loss of access of the study graft for hemodialysis.
2 years
AVG Primary Patency
Time Frame: 2 years
The percentage of subjects free from the first occurrence of either access thrombosis or an access procedure performed to maintain access patency.
2 years
Incidence of Treatment-Emergent Adverse Events
Time Frame: 2 years
All device and/or procedure-related events and all major adverse events that reasonably suggest the involvement of the EndoForce and that require or result in any of the following: death, emergent surgery, events requiring hospitalization, events requiring percutaneous interventions, vascular access infection requiring treatment, significant bleeding, pseudoaneurysm and serious adverse events. EndoForce migration, inadequate seal and leakage will also be collected acutely and at each in-person follow-up visit.
2 years
Number of AVG Interventions to Maintain Patency
Time Frame: 2 years
The number of AVG interventions until access abandonment or through study completion.
2 years
Number of Participants with Acute Device Success
Time Frame: Through end of procedure
AV graft flow at the end of the procedure as determined by palpable graft thrill and/or audible bruit, without significant bleeding or emergent surgery.
Through end of procedure

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 13, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
