What this trial studies

This trial evaluates the safety and tolerability of a single unilateral administration of AAVAnc80-antiVEGF at three different dose levels. It also assesses the Akouos delivery device's effectiveness in achieving the desired therapeutic outcome. The focus is on patients with unilateral, progressive vestibular schwannoma larger than 2 mm and associated profound hearing loss. Participants will be monitored for their compliance with trial requirements and will be invited to join a long-term follow-up study.

Who should consider this trial

Good fit: Ideal candidates are individuals with unilateral, progressive vestibular schwannoma larger than 2 mm and profound hearing loss in the affected ear.

Not a fit: Patients with bilateral vestibular schwannoma or those who have undergone prior surgery or radiation therapy for vestibular schwannoma may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could provide a novel treatment option for patients suffering from vestibular schwannoma and associated hearing loss.

How similar studies have performed: Other studies have explored gene therapy approaches for similar conditions, but this specific application of anti-VEGF gene therapy is novel.

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.
