About this study

Official title: Creation of a Prospective Data Collecting Registry for Genicular Artery Embolization for Arthritis (GAE)

The goal of this study is to create a prospective registry (<100 patients) to show the effectiveness of the genicular artery embolization procedure overtime in reducing bilateral or unilateral osteoarthritic knee pain as measured by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score.

Read the detailed description

Knee osteoarthritis (KOA) is a pervasive and debilitating disease, affecting over 15 million people in the US alone. Symptoms include pain, stiffness, and ultimately loss of joint function. Medical therapies are the mainstay of treatment as surgical joint replacement is typically reserved for advanced disease. Only half of patients treated by medical management with disease not severe enough to warrant surgery experience adequate pain relief, resulting in an estimated population of 3.6 million Americans who are left suffering. Genicular artery embolization (GAE) is a novel, minimally invasive treatment that uses radiologic techniques to catheterize pathologically hyperemic genicular arteries using live X-ray guidance with subsequent occlusion of these vessels using injected microspheres. GAE is performed to inhibit or blunt synovial inflammation thought to be a primary phenotype of KOA. Multiple small sized cohort studies have shown to significantly reduce pain associated with KOA. This procedure has been performed in the University of Chicago Medical Center and showed its effectiveness and safety. In this study, the investigators plan to establish a prospective database of patients undergoing GAE for KOA in order to further characterize its effectiveness with a longer follow-up and larger sample size. The investigators also hope to establish Magnetic Resonance Imaging (MRI) as an objective imaging biomarker for positive remodeling of the knee that occurs after GAE due to decreased synovitis. If the results of this study are positive, the investigators plan to conduct a definitive sham-controlled study to justify the use of GAE in medically refractory KOA and help provide a treatment option to the millions of people with this disease.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)

    The investigators will describe differences in pain response with Genicular Artery Embolization (GAE) compared to a sham procedure when treating medically refractory mild to moderate Knee Osteoarthritis (KOA) at 12 months as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain subscale score. A higher score index a higher pain level while a lower score indicates lower pain levels. The score range is 0 to 100.

    Measured: 1 year of enrollment/patient

Secondary outcomes (1)
  1. Incidence of Genicular Artery Embolization Emergent Adverse Events

    The investigators will assess GAE-related adverse events to better understand its net benefit. Angiography with embolization is an invasive procedure with knowns risks that include bleeding (i.e. hematoma, arterial perforation), infection, and non-target embolization.35 Outcomes will be recorded as intra-procedure events along with assessments at 3, 6, 9, and 12 months post procedure. Complications will be recorded per the Society of Interventional Radiology Quality Improvement Standards for Percutaneous Transcatheter Embolization.

    Measured: 1 year of enrollment/patient

Questions about this trial

What is this clinical trial studying?

An observational study of Knee Osteoarthritis and Knee Osteoarthritis (Knee OA), run by University of Chicago at 1 site in United States.

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 13 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: looking for participants now, as of the sponsor's last update on 13 May 2026. 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 United States. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Tiana Jackson (773.795.7030, Tiana.Jackson@bsd.uchicago.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) (time frame: 1 year of enrollment/patient). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06781463, which also lists 5 linked publications.

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 13 May 2026.
