Interventions

NameTypeDescription
VonaprumentDRUGForm: solution for injection; Route of Administration: IVT injection
Sham AdministrationOTHERForm and Route of Administration: to mimic IVT injection (includes placement of the blunt opening of an empty, needleless syringe barrel on the conjunctiva in the inferotemporal quadrant of the eyeball to stimulate the pressure of an injection).
ANX007DRUGForm: solution for injection; Route of Administration: IVT
Sham comparatorOTHERForm and Route of Administration: pressure to mimic IVT injection
2.5mg ANX007BIOLOGICALA single dose of 2.5mg ANX007 will be administered via IVT injection into the study eye at Day 1 and Day 29.
5.0mg ANX007BIOLOGICALA single dose of 5.0mg ANX007 will be administered via IVT injection into the study eye at Day 1 and Day 29.
Sham ProcedureOTHERThe sham injection is preformed by applying pressure to the eye at the location of a typical IVT injection using the blunt end of a syringe without a needle.

Frequently asked questions about Vonaprument (ANX007)

What is Vonaprument (ANX007) used for?

Vonaprument is an investigational therapy being developed for geographic atrophy, a late stage form of dry age-related macular degeneration, and it has also been studied in open angle glaucoma. It is not yet approved for any indication and remains in clinical development.

What does Vonaprument target?

Vonaprument targets C1q, a component of the complement system. By binding C1q, the small molecule is designed to inhibit complement activation, a pathway implicated in retinal and optic nerve damage. This mechanism underlies its development in geographic atrophy and open angle glaucoma.

Who is developing Vonaprument?

Vonaprument is being developed by Annexon, Inc., which trades on the Nasdaq under the ticker ANNX. The company holds the asset, formerly known as ANX007, and is running its late stage clinical program in geographic atrophy.

What phase is Vonaprument in?

Vonaprument is in Phase 3 development. Two Phase 3 trials are underway in geographic atrophy, one active and not recruiting and one not yet recruiting, following a completed Phase 2 study and an earlier Phase 1 study in open angle glaucoma. It is investigational and has not been approved.

What clinical trials is Vonaprument in?

Vonaprument has been evaluated across four registered studies. These include the Phase 3 trials NCT06510816 and NCT07807969, the completed Phase 2 trial NCT04656561 in geographic atrophy, and the completed Phase 1 trial NCT04188015 in primary open angle glaucoma. Total enrollment across these studies is 1,534 participants.

Is Vonaprument the same as ANX007?

Yes. Vonaprument and ANX007 refer to the same investigational compound. The asset was formerly called ANX007 and is also referenced as 2.5mg ANX007, and it is now known as Vonaprument. Annexon, Inc. is the developer behind both names.
