A Promising New Hope for a Durable Macular Degeneration Treatment: MDM2 Inhibitors
Improved Macular Degeneration Therapy Displays Encouraging Results
In a groundbreaking development, a team of researchers from the University of North Carolina (UNC) School of Medicine, and collaborators, have made promising strides in the fight against macular degeneration using a class of drugs known as MDM2 inhibitors. Their findings, published in the latest issue of the Journal of Clinical Investigation, could pave the way for a more sustainable treatment for this eye disease that causes significant vision loss among older Americans.
Macular degeneration, a major cause of vision impairment among the US elderly, is a condition that deteriorates the macula, which supplies central vision, making everyday tasks like driving, reading, and watching TV increasingly challenging. When it develops after age 50, it's referred to as age-related macular degeneration (AMD).
AMD typically begins as a "dry" form, causing blurred vision or blind spots, but about 20% of those affected develop the "wet" form, where abnormal blood vessels grow in the eye, causing fluid or blood leaking and eventual vision loss. Currently, the best treatment involves an antibody, anti-VEGF, injected into the eye, but the injections need to be administered every 4 to 8 weeks, which makes the treatment costly, time-consuming, and high-risk due to infection exposure.
Recent research and clinical trials involving MDM2 inhibitors have been mostly focused on solid tumors and multiple myeloma, not macular degeneration[1]. However, the potential offered by these inhibitors to directly target the abnormal blood vessels, rather than just the growth factors that lead to their formation, presents an opportunity for a long-lasting and potentially life-changing treatment.
Prof. Sai Chavala, from the UNC School of Medicine and director of the Laboratory for Retinal Rehabilitation, is optimistic about the implications of this study on mice: “Such a treatment would reduce patients' overall risk of eye infections, and also potentially lower the economic burden of this condition by reducing treatment costs."
The hope is that MDM2 inhibitors will provide a more sustainable solution by regressing the abnormal blood vessels responsible for the vision loss associated with macular degeneration. By activating a protein called p53, a master regulator protein that decides whether a cell lives or dies, MDM2 inhibitors can initiate the cell death process in these abnormal blood vessels[2].
MDM2 inhibitors also appear to offer advantages over other treatments currently being trialed for wet AMD, such as low-dose radiation, which can cause DNA damage. MDM2 inhibitors activate p53 without damaging DNA, and they can be administered by eye injection, whereas some forms of radiation treatments require surgery[2].
According to enrichment data, as of mid-2025, MDM2 inhibitor research for macular degeneration in humans appears to be either in its infancy or secretive, as no clinical trials or systematic reviews are currently referenced or accessible. Despite this, Prof. Chavala's work at the forefront of eye disease research offers a glimmer of hope for better, more enduring treatments for macular degeneration.
