Could stem cell secretions protect hearing during implant surgery?
NCT ID NCT06545175
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tests whether a substance called VSF1.01, made from stem cell secretions, can safely reduce trauma to the inner ear during cochlear implant surgery. Eleven adults with severe hearing loss will receive the treatment directly into the cochlea before the implant is placed. The study primarily checks for side effects, and also looks at whether it helps preserve nerve responses and improve speech understanding.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
VSF1.01 (a solution enriched with extracellular vesicles from human umbilical cord mesenchymal stem cells)
What this could lead to
If successful, this could lead to a treatment that reduces inner ear damage during cochlear implant surgery, potentially improving hearing outcomes.
What could go wrong
This is an early-phase trial with only 11 participants, so results may not apply to everyone. The treatment is new and its safety and effectiveness are not yet proven.
