About this trial

Skylark Bio is conducting a study of an investigational new drug called SKY-GJB2 and its delivery device, the SKY-CAT. SKY-GJB2 is a gene therapy that is being developed to treat children who have hearing loss due to changes in the GJB2 gene (also referred to as Connexin 26). The SKY-CAT is a device that delivers the gene therapy.

The purpose of this study is to:

Learn about the safety and tolerability (does not cause ongoing discomfort) of SKY-GJB2 Evaluate the efficacy of SKY-GJB2 (how well is works)

Eligibility criteria

Subject's parent(s)/guardian(s) provide informed consent before the initiation of study-related procedures.

Disqualifiers

Subject has non-GJB2 mediated hearing loss including genetic, syndromic, or non-syndromic hearing loss that is not associated with GJB2 mutations.

Subject has autosomal dominant nonsyndromic hearing loss due to GJB2 mutation.

No response on ABR testing.
