CRANBURY, N.J., July 22, 2021 /PRNewswire/ — Palatin Technologies, Inc. (“Palatin”) (NYSE American: PTN), a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin peptide receptor system, today announced that Carl Spana, PhD, President and CEO of Palatin, presented today at the Eyecelerator@ASCRS Conference in Las Vegas, NV.  The presentation is one of several Company Showcases in the general session titled: “Dry Eye: The Need for Innovation.”  The topics of the presentation were melanocortins’ role in resolving inflammation and presentation from a Phase 2 study with Palatin’s compound PL9643 for dry eye disease (DED) and included information about Palatin’s research program with melanocortins in retinal disease. 

Eyecelerator is a partnership between the American Academy of Ophthalmology (AAO) and the American Society of Cataract and Refractive Surgery (ASCRS). Its mission is to connect entrepreneurs, investors, companies, and physicians to advance ophthalmic innovation through live conferences, virtual programming, and a next-generation networking platform.

Palatin is on track to initiate a Phase 3 clinical study with PL9643 in patients for the treatment of dry eye disease during the fourth quarter of calendar year 2021, with data readout expected in the second half of calendar year 2022. If the program progresses as planned, an NDA submission is targeted for the second half of calendar year 2023.

PL9643 is a novel melanocortin agonist, delivered to the eye topically via eyedrops.  Palatin previously announced positive results in its Phase 2 study of PL9643 for the treatment of DED. Statistically significant improvement in multiple signs and symptoms was achieved in the moderate to severe patient population after 2 weeks of dosing and at the 12-week visit. There were no safety signals identified and PL9643 had excellent ocular tolerability.

About Melanocortins and Inflammation

The melanocortin receptor (“MCr”) system has effects on food intake, metabolism, sexual function, inflammation, and immune system responses. 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 significant pharmacological effects. 

Many tissues and immune cells located in the eye express melanocortin receptors, empowering our opportunity to directly activate natural pathways to resolve disease inflammation.

About Dry Eye Disease (DED)

Dry eye disease is a common inflammatory disease that, left untreated, can become extremely painful and lead to permanent damage to the cornea and vision. Dry eye disease affects the cornea and conjunctiva of the eye resulting in irritation, redness, pain, and blurred vision. It is estimated to affect over 20 million people in the United States. The disease is characterized by insufficient moisture and lubrication in the anterior surface of the eye, leading to dryness, inflammation, pain, discomfort, irritation, diminished quality of life, and in severe cases, permanent vision impairment. Existing therapy for dry eye disease is generally regarded as inadequate by many physicians and patients, and often requires weeks or months to demonstrate activity.
