Study summary

ADVM-022-07 is an observational long-term extension (OPTIC-EXT) study assessing safety and efficacy of ADVM-022 gene therapy product, in participants with neovascular, or exudative (wet), age-related macular degeneration (nAMD).

Read the detailed description

ADVM-022 (AAV.7m8-aflibercept) is a gene therapy product developed for the treatment of neovascular (wet) age-related macular degeneration (wet AMD). Wet AMD is a serious condition and the leading cause of blindness in the elderly. The available therapies for treating wet AMD require life-long intravitreal (IVT) injections every 4-12 weeks to maintain efficacy. A one-time IVT administration of ADVM-022 has the potential to treat wet AMD by providing durable expression of therapeutic levels of intraocular anti-VEGF protein (aflibercept) and maintaining the vision of patients. ADVM-022 is designed to reduce the current treatment burden which often results in undertreatment and vision loss in patients with wet AMD receiving anti-VEGF therapy in clinical practice.

ADVM-022-07 is an observational long-term extension (OPTIC-EXT) study assessing safety and efficacy of ADVM-022 gene therapy product in participants with neovascular or exudative (wet), age-related macular degeneration (nAMD) previously treated in the OPTIC parent study (Clinical Protocol No. ADVM-022-01 [OPTIC] - NCT03748784). There is no investigational treatment administered in this study.

In Part 1 of the OPTIC-EXT study participants will roll over from the OPTIC parent study and will be followed for 3 additional years (following 2-years of assessment period in the OPTIC parent study). In Part 2 of the OPTIC-EXT study consenting participants will have 5 annual in-clinic assessments for an additional 5 years of long-term follow-up following the completion of OPTIC-EXT (Part 1). As such participants who complete the parent study as well as Part 1 and Part 2 of the OPTIC-EXT study will have had 10 years of total long-term follow-up.

  • Willing and able to provide

Exclusion criteria

Exclusion Criteria:

  • None
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 10, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
