Palatin to Present at the Association for Research in Vision and Ophthalmology (ARVO) 2022 Annual Conference

Posters highlight Palatin's ocular research and PL9643 Phase 2 clinical data

CRANBURY, N.J., May 2, 2022 /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 two poster presentations at the Association for Research in Vision and Ophthalmology (ARVO) Annual Conference being held May 1-4 in Denver.

Palatin Technologies, Inc.
Palatin Technologies, Inc.

The posters reflect data on Palatin's novel ocular research program and from a Phase 2 study with Palatin's compound PL9643 for dry eye disease (DED).

Poster details:
Session: Dry Eye, Clinical
Posterboard #: A0288
Session Date: May 2, 2022
Session Time: 2:30-4:30 pm EDT
Poster Title: Efficacy and safety of the melanocortin agonist PL9643 in a phase 2 study of subjects with dry eye disease

Session: Biochemistry and Molecular Mechanisms of Diabetic Retinopathy
Posterboard #: A0047
Session Date: May 4, 2022
Session Time: 12:00-2:00pm EDT
Poster Title: Efficacy and impact of the melanocortin receptor agonists PL8177 and PL9654 in an STZ-rat model of diabetic retinopathy

The posters will be available on Palatin's website at: www.palatin.com.

Palatin's innovative and comprehensive research regarding the mechanism of action and efficacy of melanocortins in tissues and animals continues to produce consistent and robust data supporting melanocortins' role in the process of resolving inflammation and information supporting further development of Palatin's compounds for the treatment of inflammatory conditions.

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.

Palatin's Phase 3 clinical study (MELODY-1) with PL9643 is currently enrolling patients, with topline data currently expected during the fourth quarter of calendar year 2022. If the program progresses as planned, an NDA submission is targeted for the first half of calendar year 2024.

About The Association for Research in Vision and Ophthalmology (ARVO)

ARVO is the largest and most respected eye and vision research organization in the world. Their members include nearly 11,000 researchers from over 75 countries. The mission of ARVO is to advance research worldwide into understanding the visual system and preventing, treating and curing its disorders. (arvo.org)

About Dry Eye Disease (DED)

DED is a common inflammatory disease that, left untreated, can become extremely painful and lead to permanent damage to the cornea and vision. DED 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 DED is generally regarded as inadequate by many physicians and patients, and often requires weeks or months to demonstrate activity.

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 in the eye (and other places, for example, the gut and kidney) express melanocortin receptors, empowering our opportunity to directly activate natural pathways to resolve disease inflammation.

About Palatin

Palatin is a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin and natriuretic peptide receptor systems, with targeted, receptor-specific product candidates for the treatment of diseases with significant unmet medical need and commercial potential. Palatin's strategy is to develop products and then form marketing collaborations with industry leaders to maximize their commercial potential.
