Frequently asked questions about AK-antiVEGF

What is AK-antiVEGF?

AK-antiVEGF is an investigational gene therapy being studied for vestibular schwannoma, a noncancerous tumor that grows on the nerve connecting the ear to the brain. It is delivered using the Akouos Delivery Device and is also known as AAVAnc80-antiVEGF via Akouos Delivery Device. It is in Phase 1 clinical development.

What is AK-antiVEGF used for?

AK-antiVEGF is being studied for the treatment of vestibular schwannoma, a tumor affecting the vestibular nerve. The Phase 1 trial enrolls adults 18 years and older with this condition. Vestibular schwannoma falls within the oncology therapeutic area for this program.

Who is developing AK-antiVEGF?

AK-antiVEGF is being developed by Eli Lilly and Company, which trades on the New York Stock Exchange under the ticker LLY. The program uses the Akouos Delivery Device for administration. Lilly is the sponsor of the ongoing clinical study of this gene therapy candidate.

What phase is AK-antiVEGF in?

AK-antiVEGF is in Phase 1 clinical development. It is an investigational therapy and has not been approved by the FDA. One Phase 1 trial is currently active and recruiting participants, with no completed trials reported for this program.

What clinical trials is AK-antiVEGF in?

AK-antiVEGF is being evaluated in one clinical trial, NCT06517888, titled Anti-VEGF Gene Therapy Trial for Vestibular Schwannoma. The Phase 1 study is recruiting in the United States and plans to enroll 27 participants. It is a controlled trial open to adults 18 years and older of all sexes.

Is AK-antiVEGF the same as AAVAnc80-antiVEGF via Akouos Delivery Device?

Yes, AK-antiVEGF is also known as AAVAnc80-antiVEGF via Akouos Delivery Device. Both names refer to the same investigational gene therapy developed by Eli Lilly and Company for vestibular schwannoma. The alternative name reflects the AAVAnc80 vector and the Akouos Delivery Device used to administer it.
