(NYSE American: PTN), a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor system, today provided an update on its clinical programs, strategic priorities, and anticipated milestones. "We continue to execute on the clinical development front and expect several key milestones from multiple programs over the next twelve months," said Carl Spana, Ph.D., President and Chief Executive Officer of Palatin. "Patient dosing has commenced in our Phase 2 clinical study of an MC4R agonist plus a GLP-1 in obese patients. Our clinical program evaluating bremelanotide co-formulated with a PDE5i for the treatment of ED in patients who do not respond to PDE5i monotherapy is expected to begin in the first half of calendar year 2025. An interim analysis readout on our Phase 2 clinical trial of PL8177 in patients with UC is expected later this calendar year. Additionally, as a result of a positive Type C meeting with the FDA and agreement on PL9643 for DED Phase 3 trial protocols and endpoints, we anticipate the initiation of pivotal clinical studies MELODY-2 and MELODY-3 in the fourth quarter of this calendar year." Dr. Spana further commented, "We are focused on the continued development of melanocortin receptor system treatments for obesity and male sexual dysfunction. We are actively engaging in discussions with potential partners and companies that have the financial and operational resources to progress PL9643 for DED, our other ocular programs, and our ulcerative colitis program, through development, approval, and into commercialization.

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.
