简要总结
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 DR with and without center involved-diabetic macular edema (CI-DME) 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 a total of 5 years post-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.

研究组 & 干预措施
Standard of Care
Dose Level (DL) 1-3 participants who received ABBV-RGX-314 in a parent study will continue to receive standard of care for the study duration.
干预措施: Standard of Care (Drug)
Supplemental Treatment
DL4 participants from parent study will be eligible to receive supplement aflibercept through a prespecified timepoint based on protocol-specified criteria if they develop worsening CI-DME or high-risk proliferative diabetic retinopathy (PDR) in the study eye.
干预措施: Aflibercept (Drug)
Supplemental Treatment
DL4 participants from parent study will be eligible to receive supplement aflibercept through a prespecified timepoint based on protocol-specified criteria if they develop worsening CI-DME or high-risk proliferative diabetic retinopathy (PDR) in the study eye.
