Palatin Technologies (symbol: PTN) is a biopharmaceutical company focused on developing first-in-class therapeutics for diseases with unmet medical needs. Rather than selling products directly to individuals or a broad base of wholesalers, Palatin primarily generates revenue through licensing agreements with larger pharmaceutical companies that handle the commercialization of its products.

Therefore, its major customers are other companies that have licensed rights to Palatin's drug candidates, particularly its commercialized product, Vyleesi (bremelanotide injection) for Hypoactive Sexual Desire Disorder (HSDD).

The major customer companies for Palatin Technologies are:

• Covis Pharma: Holds the commercialization rights for Vyleesi in North America. (Covis Pharma is a privately held company.)
• Shanghai Fosun Pharmaceutical Group Co., Ltd. (also known as Fosun Pharma): Holds the commercialization rights for Vyleesi in Greater China (mainland China, Hong Kong, Macau, and Taiwan). (Public company, symbol: HKEX: 2196, SSE: 600196)
• Kwang Dong Pharmaceutical Co., Ltd.: Holds the commercialization rights for Vyleesi in South Korea. (Public company, symbol: KRX: 009290)

• Vyleesi (Bremelanotide) for Hypoactive Sexual Desire Disorder (HSDD):
  • The global female sexual dysfunction treatment market was valued at approximately USD 489.6 million in 2024 and is projected to grow to USD 1,329.5 million by 2032.
  • In the U.S. alone, the female sexual dysfunction treatment market is projected to reach an estimated value of USD 782.3 million by 2032.

• Bremelanotide (adjunct therapy for obesity) in combination with GLP-1:
  • The global GLP-1 receptor agonist market, which includes treatments for obesity, was estimated at USD 53.46 billion in 2024 and is projected to reach USD 156.71 billion by 2030.
  • Another estimate places the global GLP-1 receptor agonist market size at USD 62.86 billion in 2025, projected to reach around USD 268.37 billion by 2034.

Palatin Technologies (PTN) is poised for potential revenue growth over the next 2-3 years, driven primarily by milestone payments from its divested Vyleesi asset and the advancement and commercialization of its pipeline products, particularly in dry eye disease and obesity.

1. Milestone Payments from Cosette Pharmaceuticals for Vyleesi: Although Palatin Technologies sold the worldwide rights for Vyleesi (bremelanotide for female hypoactive sexual desire disorder) to Cosette Pharmaceuticals in December 2023, the agreement includes potential sales-based milestone payments of up to $159 million. These payments are contingent on annual net sales ranging from $15 million up to $200 million and represent a potential future revenue stream for Palatin. Palatin retained rights for Vyleesi in obesity and male erectile dysfunction.
2. Commercialization of PL9643 for Dry Eye Disease (DED): Palatin's PL9643, a potential treatment for dry eye disease, has shown promising positive results in its Phase 3 MELODY-1 trial, demonstrating statistically significant improvements in symptoms like pain and an excellent safety profile. The DED market is significant, with an estimated 38 million affected individuals in the U.S. and a projected growth from $6.1 billion in 2024 to $7.5 billion by 2029. The FDA has confirmed the protocols for the remaining Phase 3 pivotal clinical trials (MELODY-2 and MELODY-3), with patient enrollment expected to begin in Q4 2024 and topline results anticipated by the end of 2025. A New Drug Application (NDA) submission is projected for the first half of 2026. Palatin's strategy involves forming marketing collaborations with industry leaders to maximize the commercial potential of its products, indicating a potential licensing or partnership revenue opportunity for PL9643.
3. Advancement and Potential Partnerships for Obesity and Weight Loss Management Programs: Palatin is strategically focused on developing Melanocortin-4 receptor (MCR4) agonists for obesity treatment, a market projected to exceed $100 billion annually. The company is on track to advance both novel acting, long-acting MCR4 receptor peptide agonists and an orally active MCR4 selective small molecule agonist (PL7737) into IND-enabling activities and clinical studies in calendar year 2025. A Phase 2 study for obesity treatment has been completed, with topline data expected soon (as of April 2025), and a trial was set to begin in Q3 2024 with data in the first half of 2025, which the company sees as an excellent partnering opportunity. Recent proceeds from a public offering in November 2025 are intended to support the development of this obesity program.
4. Out-licensing and Partnerships for PL8177 (Ulcerative Colitis) and other pipeline assets: Palatin is actively seeking partnerships for its ulcerative colitis program (PL8177) and other pipeline assets, such as those targeting diabetic kidney disease. A Phase 2 clinical study for oral PL8177 in ulcerative colitis had an interim analysis targeted for Q1 2024, with topline results expected in H1 2024. Successful clinical development and subsequent out-licensing agreements for these programs could generate additional revenue through upfront payments, milestones, and royalties. Palatin also retains the rights to bremelanotide for male erectile dysfunction, with a Phase 3 program planned for the second half of 2025, and data expected in the second half of 2026.
