Brief Summary

Knee OsteoArthritis (KOA) is a common disease associated with pain and impaired function. Many patients are not relieved of their symptoms with enough efficacy by conservative treatments. Genicular Arteries Embolization (GAE) is a new minimally invasive endovascular treatment allowing symptoms relief. The investigator previously demonstrated the safety of GAE using an ethiodized oil-based emulsion for the treatment of painful knee osteoarthritis in a first-in-man single-arm clinical trial called LipioJoint-1 (clinicaltrials.gov: NCT04733092; EUDRACT: 2020-002206-10). This phase 1 study also provided encouraging evidence of GAE efficacy on knee pain and function. The purpose of LipioJoint-2 study is to assess GAE efficacy using an ethiodized oil-based emulsion for the treatment of painful knee osteoarthritis in a multicenter, prospective, randomized sham-controlled clinical trial.

Outcome Measures

Primary Outcomes (1)

  • Change of pain assessed by a Visual Analogue Scale (VAS) at 3 months compared to randomization.

    VAS pain is a validated, self-reported instrument assessing average pain over the past 48 hour period. Score ranges from 0 (no pain) to 100 (worst possible pain).

    3 months

Secondary Outcomes (15)

  • Change of pain assessed by a Visual Analogue Scale (VAS) at 1 month compared to randomization.

    1 month

  • Change of pain assessed by a Visual Analogue Scale (VAS) at 6 months compared to randomization.

    6 months

  • Change of pain assessed by a Visual Analogue Scale (VAS) at 12 months compared to randomization.

    12 months

  • Change of the patient's global assessment of her/his health measured by the Visual Analogue Scale of EQ-5D questionnaire (EQ VAS) at 1, 3, 6, 12 months compared to randomization.

    Up to 12 months

  • Change of the Western Ontario and McMaster Universities Arthritis (WOMAC) total and sub-scores (pain, function,stiffness) at 1, 3, 6, 12 months compared to randomization.

    Up to 12 months

  • +10 more secondary outcomes

Study Arms (2)

Embolization group

EXPERIMENTAL

Genicular arteries embolization of the target knee will be performed using an ethiodized oil-based emulsion (3:1 mix of ethiodized oil and contrast agent ioversol 300 mgI/ml); 86 patients will be allocated to embolization group (2:1 randomization).

Drug: Ethiodized Oil-based emulsion

Sham group

SHAM COMPARATOR

All the gestures will be mimed using the same equipment as in GAE group. Superficial femoral artery catheterization, selective catheterization of target arteries and emulsion injection will be mimicked by the interventional radiologist (table movements, syringes manipulation) to keep the patient blind from the actual treatment. 44 patients will be allocated to sham group (2:1 randomization).

Procedure: Sham-operation

Interventions

Embolization of genicular arteries

Embolization group

Mimicked catheterization and embolization of genicular arteries

Masking Details
Only the personal of the Interventional Radiology department of HEGP (only unblinded center) will have the knowledge of the trial arm. Patient will be blinded from randomization arm using headphones and/or virtual headset. The research personnel will be trained accordingly and will keep a separate file with patient's images to ensure that they are not transferred on the Pacs system (Carestream). The research assistant will discard the products after completion of the procedure in specific containers, that will not be accessible to the patient or to nurses and technicians directly involved in the current patient's care. Patient's blindness will be assessed using a blinding index after GAE and at the 3-month follow-up visit. The proposed blinding index is scaled to an interval of -1 to 1, 1 being complete lack of blinding, 0 being consistent with perfect blinding and -1 indicating opposite guessing which may be related to unblinding.
