Positive Developments in Wet AMD Treatment
REGENXBIO Inc. (NASDAQ: RGNX) has recently announced encouraging findings from the Phase II fellow eye sub-study, focusing on the efficacy of ABBV-RGX-314, a gene therapy aimed at treating bilateral wet age-related macular degeneration (AMD). This innovative treatment highlights a significant reduction in the treatment burden for patients and opens new avenues for future therapies.
Study Highlights and Results
The Phase II study presented compelling outcomes, showcasing a remarkable 97% reduction in the annualized treatment burden within nine months after the ABBV-RGX-314 therapy. This therapy has demonstrated a promising safety and efficacy profile, consistent with previous studies, and has been well-tolerated among participants.
Safety and Efficacy Profile
Key findings from this sub-study reveal that participants experienced no cases of intraocular inflammation despite no use of prophylactic steroids. Among the treated patients, 100% required either zero or just one supplemental injection, and 78% of the patients reported being completely injection-free after nine months.
Sustained Visual Outcomes
In addition to treatment burden reduction, patients showed sustained best-corrected visual acuity (BCVA) and central retinal thickness (CRT). This improvement suggests that ABBV-RGX-314 could offer a long-lasting solution, enhancing patients' overall quality of life by addressing the challenges posed by frequent injections.
The Pivotal Role of Gene Therapy
According to Curran Simpson, President and CEO of REGENXBIO, this study represents a significant milestone in the field of gene therapy for retinal diseases. The ability to treat both eyes improves patient outcomes and has the potential to redefine how wet AMD is managed. The data reflects the hope of providing a one-time effective treatment that can alleviate the long-term vision threats faced by millions globally.
About ABBV-RGX-314
ABBV-RGX-314 is developed through valuable collaboration with AbbVie, with the goal of offering a single treatment option for wet AMD and chronic retinal conditions. Utilizing the NAV AAV8 vector, ABBV-RGX-314 is designed to impede the vascular endothelial growth factor (VEGF), which is crucial in the formation of new, leaky blood vessels that can lead to vision impairment.
Understanding Wet AMD
Wet AMD leads to significant vision loss through the abnormal growth of blood vessels in the retina. Millions worldwide suffer from this affliction, emphasizing the pressing need for innovative therapies like ABBV-RGX-314. With current treatments requiring regular injections, the strain on patients becomes a daunting barrier to effective care.
About REGENXBIO

Their pipeline includes ABBV-RGX-314 as well as other promising therapies targeted at rare and chronic conditions. With thousands of patients treated, REGENXBIO is on a mission to revolutionize healthcare for those at risk.
Frequently Asked Questions
What are the main findings of the REGENXBIO Phase II study?
The study indicated a 97% reduction in the treatment burden for patients using ABBV-RGX-314, with most participants requiring few or no additional injections.
How was the safety profile of ABBV-RGX-314 in the study?
The therapy was well tolerated, with no cases of drug-related serious adverse events or intraocular inflammation observed.
What does ABBV-RGX-314 target?
ABBV-RGX-314 targets vascular endothelial growth factor (VEGF) to inhibit the formation of leaky blood vessels in the retina.
Why is bilateral treatment significant?
Bilateral treatment is crucial as many wet AMD patients ultimately require treatment in both eyes, making this approach potentially transformative.
What other conditions does REGENXBIO aim to treat?
Besides wet AMD, REGENXBIO is investigating ABBV-RGX-314 for other chronic retinal diseases, ensuring a wider impact on patients' health.
