Trial Summary

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, it mentions that knee pain should be resistant to conservative treatments like anti-inflammatory drugs, which suggests you might continue some medications. Please consult with the trial coordinators for specific guidance.

What data supports the effectiveness of the treatment Embozene™ Microspheres for osteoarthritis?

Research shows that using microspheres for arterial embolization can relieve pain in patients with knee osteoarthritis, especially when other treatments haven't worked. This method has also been effective in reducing pain from other conditions, like painful tumors, suggesting it might help with osteoarthritis too.12345

How does the treatment Embozene™ Microspheres for osteoarthritis differ from other treatments?

Embozene™ Microspheres offer a unique approach by using arterial embolization, which involves blocking blood flow to reduce inflammation and pain in osteoarthritis, unlike traditional treatments that focus on direct joint injections or oral medications.678910

What is the purpose of this trial?

This trial is testing a new treatment where tiny beads are used to block certain blood vessels in the knee. It is aimed at people with mild to moderate knee osteoarthritis who might not benefit from usual treatments. The goal is to see if blocking these blood vessels can safely reduce pain and swelling.

Treatment Details

Interventions

  • Embozene™ Microspheres
Trial Overview The study tests if blocking blood flow to the knee using Embozene™ Microspheres through an artery can help with osteoarthritis pain. It's a single-group trial without a placebo where patients are monitored for one year to see how safe and effective this treatment is.
Participant Groups
1Treatment groups
Experimental Treatment
Group I: Embolization GroupExperimental Treatment2 Interventions
23 participants who are aged between 30 to 75 years old, with grade 2 or 3 knee OA on the most recent knee radiographs obtained within 6 months of intervention. Each individual participant will be enrolled for approximately 13 months to complete all study visits from the initial screening visit to last follow up at 12-months post intervention.

Findings from Research

Genicular artery embolization (GAE) using permanent microspheres in 38 patients with mild to moderate knee osteoarthritis showed significant pain reduction, with mean visual analogue scale (VAS) scores improving from 60 at baseline to 36 at 3 months and 45 at 1 year.
The procedure was found to be safe, with only mild self-limiting adverse events reported, and significant improvements in knee MRI scores and patient-reported outcomes, indicating potential efficacy for managing knee osteoarthritis.

Bland embolization using microspheres provided effective pain relief for 90% of the 20 patients with painful malignant musculoskeletal tumors, indicating its efficacy in managing pain associated with these tumors.
The procedure was generally safe, with only 20% of patients experiencing grade-3 adverse events, and no severe complications (grade-4 or grade-5), suggesting it is a viable option for pain management in this patient population.

Transcatheter arterial embolization was performed on 14 patients with mild to moderate knee osteoarthritis, resulting in significant pain relief as measured by the WOMAC pain scores, which improved from 12.2 to 3.3 at 1 month and further to 1.7 at 4 months.
The procedure was safe, with no major adverse events reported, and the improvements in pain and function were maintained for up to 19 months after treatment.
