Palatin Provides Update on Anticipated 2025 Corporate Milestones

• Obesity programs:
  • Phase 2 BMT-801 clinical study with MC4R agonist bremelanotide plus GLP-1/GIP dual agonist tirzepatide
    • Topline results expected 1Q calendar year 2025
  • General obesity, weight loss management, and rare neuroendocrine and genetic diseases, including hypothalamic obesity
    • Multiple clinical trials targeted to commence 2H calendar year 2025 with long-acting MC4R peptide and/or MC4R oral small molecule compounds
• Dry eye disease and other ocular programs, ulcerative colitis, and diabetic nephropathy programs:
  • Program specific licensing/collaboration and spinout discussions ongoing with multiple deals targeted for calendar year 2025

CRANBURY, N.J., Jan. 28, 2025 /PRNewswire/ -- Palatin Technologies, Inc. (NYSE:PTN), a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor system (MCRS), today provided an update on anticipated corporate milestones expected to occur in calendar year 2025.

"We are poised for a transformational and defining year in 2025, focusing on reporting the topline data of our Phase 2 BMT-801 clinical study evaluating the co-administration of bremelanotide with tirzepatide on reducing body weight, with the readout expected later this quarter," said Carl Spana, Ph.D., President and Chief Executive Officer of Palatin. "The high discontinuation rate (67%) of obese patients on currently approved therapies resulting from side effects and a weight-loss plateau effect in the first year, points to a need for additional safe and effective treatments for obesity. We are targeting to start multiple clinical trials in the second half of calendar year 2025 with a novel and proprietary long-acting MC4R peptide and/or an MC4R selective oral small molecule compound for the treatment of general obesity and weight loss management, as well as obesity associated with rare neuroendocrine and genetic diseases."

"The central melanocortin system has a fundamental role in regulating energy storage and feeding behaviors. MC4R is a well validated target for treating obesity with MC4R agonists having demonstrated in multiple clinical studies significant reductions in caloric intake and weight loss," continued Dr. Spana. "As the leading MCRS development company, Palatin has unique expertise, broad intellectual property coverage and an extensive library of compounds from which to draw to develop MC4R agonists for the treatment of obesity. Our novel MC4R agonists could play a vital role in treating obesity as monotherapy or in combination with existing treatments."

Expected 2025 Milestones

Obesity Programs

• Topline results from our Phase 2 BMT-801 'signal detection' clinical study with MC4R agonist bremelanotide plus a glucagon like peptide-1/gastric inhibitory polypeptide (GLP-1/GIP) dual agonist tirzepatide, expected in the first quarter of calendar year 2025.
  • Primary objective: Demonstrate that co-administration of bremelanotide with tirzepatide is safe and has a significant effect on reducing body weight.
• General obesity, weight loss management, and orphan/rare neuroendocrine and genetic diseases, including hypothalamic obesity:
  • Potential for monotherapy or combination (with a GLP-1 agonist) therapy.
  • Investigational new drug (IND) enabling activities expected to commence 1Q calendar year 2025.
  • Filing of INDs anticipated 2H of calendar year 2025.
  • Commencement of Phase 1 clinical studies targeted for 4Q calendar year 2025.

Dry eye disease (DED) and other ocular programs, ulcerative colitis (UC), and diabetic nephropathy programs

• Program specific licensing/collaboration and spinout activities ongoing with multiple deals targeted for calendar year 2025.
• DED
  • Concluded positive Type C meeting with the FDA and reached agreement on sign and symptom endpoints for remaining two Phase 3 pivotal trial protocols, with patient enrollment prepared to commence 1H calendar year 2025.
• UC
  • Report topline results from our Phase 2 clinical study of PL8177 oral formulation for the treatment of UC later this quarter.

About Melanocortin 4 Receptor Agonists Effect on Obesity

Genetic analysis has identified the melanocortin 4 receptor (MC4R) of the paraventricular nucleus of the hypothalamus as playing a central role in appetite regulation. Genetic mutations that inhibit signaling in the MC4R pathway lead to hyperphagia, decreased energy expenditure and early-onset obesity; such mutations have been identified as the cause of several rare genetic obesity disorders. Agouti-related peptide is an endogenous antagonist of the MC4R that works with neuropeptide Y to stimulate appetite, whereas MC4R agonists such as α- and β-melanocyte-stimulating hormone promote satiety. Agonism of the MC4R therefore represents an attractive target for potential obesity treatments.

About Melanocortin Receptor Agonists

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.
