January 5, 2026 updated by: Sanjay Misra, M.D., Mayo Clinic

A Phase I, Open Label, Randomized Study of Autologous Adipose Derived Mesenchymal Stem Cells (AMSC) in Reducing Hemodialysis Arteriovenous Fistula Failure

The aim of this phase 1 study is to determine the role of autologous adipose derived mesenchymal stem cells in the reduction of hemodialysis arteriovenous fistula failure when applied during the time of surgical creation.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria

  • Patient between 18 and 85 years old
  • Patient currently on hemodialysis or pre-dialysis and planned creation of an upper extremity AV fistula with suitable anatomy
  • Ability to communicate meaningfully with investigative staff, competence to give written informed consent, and ability to comply with entire study procedures
  • Life expectancy of at least 24 months

Exclusion Criteria

  • Malignancy or treatment for malignancy within the previous 6 months
  • Immunodeficiency including AIDS / HIV or Active autoimmune disease
  • Documented hypercoagulable state or history of 2 or more DVTs or other spontaneous intravascular thrombotic events
  • Pregnancy or breast feeding
  • Treatment with any investigational drug/ device within 60 days prior to study entry or Any other condition which in the judgment of the investigator would preclude adequate evaluation of the safety and efficacy of AMSCs and the AVF
  • Employees of the sponsor or patients who are employees or relatives of the investigator
  • History of failed organ transplant on immunosuppression

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
Hemodialysis outflow vein diameter
Time Frame: Baseline to 12 months after AVF creation
Diameter of outflow vein by ultrasound
Baseline to 12 months after AVF creation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Hemodialysis AVF Blood flow
Time Frame: Baseline to 12 months after AVF creation
blood flow by ultrasound or dialysis
Baseline to 12 months after AVF creation

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.
