Long-Term Follow-Up Study of RGX-314 Administered in the Suprachoroidal Space for Participants With nAMD

August 3, 2026 updated by: AbbVie

A Long-term Follow-Up Study to Evaluate the Safety and Efficacy of Suprachoroidal Administration of RGX-314 for Participants With Neovascular Age-Related Macular Degeneration

This is a prospective study designed to evaluate the long-term safety and efficacy of ABBV-RGX-314. Eligible participants are those who were previously enrolled in a clinical study of nAMD in which they received suprachoroidal space (SCS) administration of ABBV-RGX-314. Enrollment of each participant in the current study should occur after the participant has completed either the end of study or early discontinuation visit in the previous (parent) clinical study. Participants will be followed for up to 5 years after ABBV-RGX-314 administration (inclusive of the parent study). As such, the total study duration for each participant may vary depending on when they enroll in the current study following ABBV-RGX-314 administration in the parent study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Study Population

The sample sizes were determined by the parent studies and all participants who received an SCS administration of RGX-314 will be invited to participate in the long-term follow-up study. All Enrolled Population: Includes all participants who are enrolled in the long-term follow-up study.

Description

Inclusion Criteria:

  1. Must provide written, signed informed consent for this study.
