Directly addressing leaky blood vessels associated with macular degeneration, a vision-threatening condition affecting over 11 million U.S. citizens, has been achieved through a novel treatment, according to researchers.

Enhanced approach for macular degeneration demonstrates potential for improved outcomes.

Fresh Take: A Promising Breakthrough in the Fight Against Macular Degeneration

New research from the University of North Carolina (UNC) School of Medicine offers a glimmer of hope for a more effective, long-lasting treatment for age-related macular degeneration (AMD). This groundbreaking study revolves around MDM2 inhibitors, a class of drugs that have the potential to curb the unsightly blood vessels responsible for vision loss in those affected by the disease.

The research team, led by Sai Chavala, an assistant professor of Ophthalmology and Cell Biology & Physiology at the UNC School of Medicine, shared their findings in a recent issue of the Journal of Clinical Investigation. According to Chavala, this study could pave the way for an optimized treatment for AMD.

Macular degeneration is an eye disease that affects millions of Americans, responsible for the majority of vision loss among older individuals in the United States. The condition destroys the macula, the part of the eye that provides central vision, making everyday tasks like driving, reading, and watching TV increasingly difficult. When macular degeneration develops after age 50, it's called age-related macular degeneration (AMD).

AMD initially appears as a "dry" form, causing blurred vision or blind spots. Unfortunately, around 20% of those diagnosed with AMD progress to develop the "wet" form, where abnormal blood vessels form in the eye and leak fluid or blood, exacerbating vision loss. At present, the best treatment available utilizes an antibody known as anti-VEGF, which must be injected into the eye every 4 to 8 weeks. This treatment can be expensive, time-consuming, and carries the risk of infection.

The new research on mice offers the tantalizing possibility that MDM2 inhibitors could provide a long-lasting treatment, significantly reducing the need for injections. Chavala explains that such a treatment would lower patients' risk of eye infections and potentially lessen the financial burden of treating AMD by reducing treatment costs.

What sets MDM2 inhibitors apart from anti-VEGF treatments is their ability to target leaky blood vessels directly, while anti-VEGF therapies focus on blocking the growth factors that lead to abnormal blood vessels. This direct approach could result in a lasting effect, according to the researchers.

In their study, the team examined the MDM2 inhibitors' impact on cell cultures and mice with macular degeneration. They discovered that the drug activates a protein called p53, a crucial regulator protein that decides whether a cell lives or dies. By activating p53, they can initiate the cell death process in these abnormal blood vessels.

Additionally, MDM2 inhibitors may offer advantages over another treatment in development for wet AMD: low-dose radiation. Although both treatments trigger p53, MDM2 inhibitors do so without causing DNA damage. Furthermore, MDM2 inhibitors can be administered by eye injection, while some forms of radiation treatment require surgery.

Chavala is the founder of a company planning to commercialise new treatments for eye diseases and has filed a patent for using MDM2 inhibitors to treat these conditions. It's worth noting that, currently, MDM2 inhibitors are not well-established or recognized as treatments for AMD, and the research and clinical focus for AMD treatment are primarily centered on other molecular targets and pathways.

In 2010, researchers found that a diet rich in omega-3 fatty acids can protect seniors from AMD. However, whether MDM2 inhibitors will ultimately prove effective in treating AMD remains to be seen. For the time being, anti-VEGF treatments remain the gold standard for managing wet AMD. As research into cellular senescence and oxidative stress in AMD progresses, the potential role of MDM2 inhibitors in AMD treatment remains uncertain. Stay tuned for future updates in this exciting field!
