Revolutionary mRNA Therapy for Proliferative Vitreoretinopathy: A Promising Breakthrough in Vision Restoration
Preclinical research from Massachusetts Eye and Ear in Boston shows promise for a new mRNA-based therapy for treating proliferative vitreoretinopathy (PVR), a condition that can lead to blindness. Current treatments are limited to surgery. The study was led by Michael O’Hare, PhD, William P. Miller, PhD, and Said Arevalo-Alquichire, PhD, in collaboration with CureVac, a biopharma company.
Leo A. Kim, MD, PhD, noted that this therapy uniquely delivers mRNA treatments directly into the eye, without causing excessive inflammation. This breakthrough could provide new treatment options for PVR and similar eye disorders.
The scientific reasoning behind using mRNA therapy rests on its role in protein synthesis within cells. The researchers used various models to show that mRNA-based therapies can be safely administered in the eye. They found that RUNX1-Trap could effectively reduce cell growth and inhibit fibrosis in PVR-affected eyes and abnormal blood vessel growth in animal models.
Previous research identified RUNX1’s involvement in both abnormal blood vessel growth and fibrosis in the retina. The study focused on RUNX1-Trap, which hinders RUNX1 from activating specific genes tied to scar tissue formation. This therapy prevented scar tissue and abnormal blood vessel growth in lab and animal models.

Interview with Joseph arboleda-Velasquez, MD, PhD: Promising Developments in mRNA Therapy for Proliferative Vitreoretinopathy
In a recent study from Massachusetts Eye and ear in Boston, researchers have made notable strides towards developing an mRNA-based therapy for proliferative vitreoretinopathy (PVR), a condition that poses a severe risk of blindness. We sat down with Dr. Joseph Arboleda-Velasquez, one of the leading researchers, to discuss the implications of this groundbreaking work.
Q: Dr.Arboleda-Velasquez, can you explain the significance of the study conducted in collaboration with CureVac?
A: This study represents a major advancement in our approach to treat PVR, which currently relies exclusively on surgical intervention.by pioneering an mRNA-based therapy, we’re exploring a method that has the potential to directly target the underlying mechanisms of this disease at the cellular level, thereby offering a new therapeutic avenue.
Q: What makes mRNA therapy a promising option for eye disorders such as PVR?
A: the novelty of our approach lies in our ability to deliver mRNA treatments directly into the eye without triggering significant inflammation. This ensures that we can target the required cells efficiently while minimizing side effects, which has been a challenge in traditional treatment methodologies.
Q: Coudl you elaborate on the role of RUNX1-Trap in your research?
A: Certainly. RUNX1 is a transcription factor involved in both abnormal blood vessel growth and fibrosis – two key processes in PVR. Our therapy, RUNX1-Trap, works by inhibiting RUNX1 from activating genes that lead to scar tissue formation. In our models, we observed a marked reduction in cell growth and a suppression of fibrosis as well as abnormal blood vessel formation.
Q: It’s exciting to see such promising results in animal models. What are the next steps in this research?
A: While we’re encouraged by the findings so far, we’re aware that the transition to human applications is a complex one. Our next steps include testing the mRNA treatment in clinical settings. Additionally, we need to tackle the challenge of mRNA’s short lifespan in the body to ensure that the therapeutic effect can be sustained over time. This includes optimizing administration frequency and improving the stability of the mRNA.
Q: How do you foresee this research influencing the treatment of other vision-threatening diseases?
A: The implications of targeting RUNX1 extend beyond PVR. If we can successfully utilize mRNA to produce dominant negative molecules, we could potentially develop therapies for other retinal diseases characterized by similar underlying mechanisms. This could broaden the impact of our research and open new doors in the realm of ophthalmology.
Q: Is there anything else you would like to highlight regarding this study?
A: I believe that this study serves as a proof of concept for the use of mRNA in treating retinal diseases. It’s a pioneering effort that underscores the versatility of mRNA technology in biomedicine, and while it’s in the early stages, the potential it holds for reshaping treatment options in ophthalmology is quite profound.
Thank you, Dr.Arboleda-Velasquez,for sharing your insights with us. We look forward to following your research and its developments in the field of eye health.
While these findings are promising, the mRNA treatment has not yet been tested in humans. A challenge is that mRNA does not persist in cells for long, which makes it unclear how long the treatment effects last or how often treatments are needed. Future research will focus on extending the mRNA’s lifespan and timing the treatment correctly.
Joseph Arboleda-Velasquez, MD, PhD, emphasized that targeting RUNX1 may lead to new therapies for vision-threatening diseases. This method of using mRNA to produce dominant negative molecules could also lead to effective treatments for other conditions.
The study serves as proof of concept for the application of mRNA in treating PVR and similar eye diseases.
