(NYSE American: PTN), a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor system, today announced the presentation of a poster entitled, Melanocortin Receptor Agonist PL9588 Reduces Intraocular Pressure in Normotensive Rabbits at the Association of Research in Vision and Ophthalmology (ARVO) Annual Conference. The authors of the poster are Paul S. Kayne, Ph.D.; Alison Obr, Ph.D.; John H. Dodd, Ph.D.; Carl Spana, Ph.D., all of Palatin Technologies. The poster was presented by Paul Kayne, Ph.D. on April 24, 2023 at the ARVO conference in New Orleans and will be available on Palatin’s website at www.palatin.com.
“The Palatin research team continues to produce groundbreaking data regarding melanocortins’ utility and mechanism of action in treating ocular inflammatory diseases,” said Carl Spana, Ph.D., President and CEO of Palatin. “We are excited by the potential of PL9588 as a novel treatment for glaucoma and pending resources, plan to move into clinical development.” The poster presents data on PL9588 from a series of dose-ranging and duration-of-effect studies to establish its effects on intraocular pressure (IOP) after administration in healthy, normotensive rabbits. Topically administered PL9588 showed reductions in IOP with magnitudes similar or greater to the positive controls, latanoprost and timolol, which are FDA approved for treating glaucoma. The IOP lowering effect of a single topical dose of PL9588 persisted for 24 hours. A therapeutic melanocortin agonist could provide new options for treatment, both as a single agent or in combination with a standard of care. Given that melanocortins have been shown to provide neuroprotection in neuroinflammatory disorders, they may provide long-term benefit to patients with glaucoma in addition to reducing IOP. Palatin’s data provides support for continued development of PL9588 with the aim of providing a novel, once-daily treatment for glaucoma. “With the effects of lowering of intraocular pressure and protection of the ocular nerve, topically administered PL9588 has the potential to be a groundbreaking treatment for glaucoma patients,” said Michael Raizman, MD, practicing ophthalmologist and CMO of Palatin. “Potentially providing clinicians and patients with a topical treatment option which could save their vision would be a significant improvement to what is currently available to treat glaucoma and it’s detrimental effects on vision.” About Glaucoma Glaucoma is a condition that causes damage to the eye’s optic nerve. The condition usually occurs due to high pressure inside the eye that damages the nerve connecting the eye to the brain. Glaucoma can cause permanent vision loss and is a leading cause of blindness. Though there is no cure for glaucoma, blindness can often be prevented with early treatment. People over 60 years old are at higher risk of developing glaucoma. The rising number of glaucoma cases and increasing demand for cutting-edge therapeutic strategies are the two key factors driving the growth of the glaucoma market. As per the World Glaucoma Association, 79.6 million people worldwide developed the condition in 2020. According to a research report by Polaris Market Research*, the global glaucoma market was valued at $5.71 billion in 2021 and is projected to reach $9.77 billion by 2030. About PL9588 PL9588 is a peptide with melanocortin receptor 1 and 5 agonist activity that is being investigated as a potential treatment for glaucoma. About Melanocortin Receptor Agonists and Inflammation The melanocortin receptor (“MCr”) system has effects on inflammation, immune system responses, metabolism, food intake, and sexual function. There are five melanocortin receptors, MC1r through MC5r. Modulation of these receptors, through use of receptor-specific agonists, which activate receptor function, or receptor-specific antagonists, which block receptor function, can have medically significant pharmacological effects. Many tissues and immune cells located throughout the body, including the gut, kidney and eye, express melanocortin receptors, empowering our opportunity to directly activate natural pathways to resolve disease inflammation. Drugs based on melanocortin agonists have been approved by the FDA for treating several conditions, including inflammatory/autoimmune diseases, rare forms of genetic obesity and female sexual dysfunction.
