One-shot gene therapy aims to shrink ear tumors without surgery
NCT ID NCT06517888
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tests a gene therapy given as a single injection into the inner ear for people with a non-cancerous tumor called vestibular schwannoma. The therapy uses a harmless virus to deliver a gene that blocks blood vessel growth to the tumor, potentially stopping it from growing or shrinking it. The study will check safety and how well the delivery device works in 27 adults with hearing loss in the affected ear.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Criteria for Inclusion: 1. Presence of unilateral, progressive vestibular schwannoma. 2. Vestibular schwannoma larger than 2 mm. 3. Profound hearing loss, defined by pure-tone audiometry thresholds or word recognition score, in the affected ear. 4. Able and willing to comply with all trial requirements, including willingness to participate in a separate long term follow-up study after completion of this trial. Criteria for Exclusion: 1. Prior diagnosis of NF2 and/or bilateral vestibular schwannoma. 2. Prior surgery or radiation therapy for vestibular schwannoma. 3. Clinical history consistent with endolymphatic hydrops (documented fluctuating sensorineural hearing loss and/or episodic vertigo) in the affected ear. 4. Profound hearing loss, defined by pure-tone audiometry thresholds or word recognition score, in the unaffected ear. 5. Prior participation in a clinical trial with an investigational drug within six months prior to administration (Day 0), or any prior participation in a gene therapy clinical trial.
