Knee gel injection trial pulled before it began

NCT ID NCT06839222

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study was designed to test whether a new gel called Hydrogel OA 2% could safely relieve knee osteoarthritis pain better than a standard treatment. It planned to enroll adults with knee OA and give them one injection, then track side effects and symptom improvement for 26 weeks. However, the trial was withdrawn before any participants were enrolled, so no results are available.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Hydrogel OA 2% (a gel made from bovine gelatin and cellulose nanocrystals)

What this could lead to

If it had worked, this could have pointed toward a new injection to ease knee pain and improve function in osteoarthritis.

What could go wrong

The trial was withdrawn before enrolling anyone, so no data on safety or effectiveness exist. Early-stage device studies often fail to show benefit or may have unexpected side effects.
