About this study

Official title: Evaluation of the Safety of LipiodolⓇ Embolization in Symptomatic Digital Osteoarthritis Refractory to Conventional Treatment: a Pilot Study of 15 Patients

The goal of this clinical trial is to evaluate the safety of arterial embolization using Lipiodol® in patients with symptomatic hand osteoarthritis refractory to conventional treatment. It will also learn about the efficacy of arterial embolization with Lipiodol® in reducing pain and improving hand function.

The main questions it aims to answer are:

Read more
  • What are the side effects and complications associated with the Lipiodol® arterial embolization procedure?
  • Does arterial embolization reduce pain intensity and improve hand function?

Researchers will evaluate patients over a 6-month period to assess the safety of Lipiodol® embolization and its impact on joint pain, swelling, and functional capacity. Participants will:

  • Undergo arterial embolization with Lipiodol®
  • Participate in regular follow-ups to monitor pain relief, hand function, and any side effects
  • Have imaging studies to assess changes in joint vascularisation and damage

  33. Change From Baseline in Ghent University Scoring System (GUSS) at Month 6

    The Ghent University Scoring System (GUSS) is a radiographic scoring method specifically developed to evaluate joint damage in hand osteoarthritis. It focuses on assessing both structural damage and remodeling features visible on hand X-rays. Erosive progression and signs of repair or remodelling are scored by indicating the proportion of normal subchondral bone, subchondral plate and joint space on an 11-point rating scale (range 0-100 with 10 unit increases). A lower score indicates greater damage or remodeling. The total score is the sum of these 3 scores for the joint under consideration.

The wavelength chosen will be 785 nm and the laser head will be positioned between 15 and 20 centimetres above the hands (with a resolution of ~ 6.9 pixels/ cm2). Cutaneous blood flow in the areas of interest will be expressed as PU (perfusion unit) and/or CVC (cutaneous vascular conductance). The area of interest will be the whole hand and the area around each hand joint.

    Measured: Before embolisation and 0, 15, 30, 45, 60, 75, 90, 105 and 120 minutes post embolisation

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing embolization therapy in people with Osteoarthritis, run by University Hospital, Grenoble at 1 site in France.

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 7 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 5 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 France. 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 Xavier Romand, MD, PhD (0476767223 ext. +33, xromand@chu-grenoble.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number and Frequency of Embolisation-Related Adverse Events as Assessed by CTCAE (time frame: From embolization to 6 months after embolization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 5 May 2026.
