Frequently asked questions about Ixo-vec

What is Ixo-vec used for?

Ixo-vec is being developed for the treatment of neovascular age-related macular degeneration, also called wet AMD, a form of age-related vision loss driven by abnormal blood vessel growth in the retina. It is an investigational gene therapy given as an intraocular treatment and is not yet approved for commercial use.

How does Ixo-vec work?

Ixo-vec is a gene therapy, which means it delivers genetic material into retinal cells rather than supplying a conventional drug repeatedly. It belongs to the AAV vector gene therapy class. The goal of this approach is to enable the eye to produce a therapeutic protein continuously, reducing the need for frequent injections.

Who is developing Ixo-vec?

Ixo-vec is being developed by Adverum Biotechnologies, Inc., a clinical-stage biotechnology company that trades under the ticker symbol ADVM. Adverum is running the clinical program for the asset in ophthalmology, with a focus on neovascular age-related macular degeneration.

What phase is Ixo-vec in?

Ixo-vec is in Phase 3 clinical development. It is an investigational gene therapy and has not been approved by the FDA. The program has received both Regenerative Medicine Advanced Therapy (RMAT) and Fast Track designations from the FDA, which are intended to support and expedite development of therapies for serious conditions.

What clinical trials is Ixo-vec in?

Ixo-vec is being studied in three registered trials. The Phase 3 AQUARIUS study, NCT07482176, is recruiting with a planned enrollment of 534 participants. A second Phase 3 study, NCT06856577, is active but not recruiting with 311 participants. A Phase 2 contralateral dosing study, NCT07630649, is recruiting 15 participants.

Is Ixo-vec the same as ixoberogene soroparvovec?

Yes. Ixo-vec is the short name for ixoberogene soroparvovec, the full name of the gene therapy Adverum Biotechnologies is developing for neovascular age-related macular degeneration. The two names refer to the same investigational asset, so trial records and company updates may use either form.
