CRANBURY, N.J. , Nov. 14, 2024/PRNewswire/ - Palatin Technologies, Inc. (NYSE American: PTN), a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor system, today announced operating and financial results for its fiscal first quarter ended September 30, 2024.

"With the establishment of pharmacotherapy as the primary treatment for the millions of obese patients and the high discontinuation rate (67%) of obese patients on current therapies resulting from side effects and a weight-loss plateau effect in the first year, we believe our MC4R long-acting peptide and oral small molecule compounds could address the unmet needs and challenges of these treatments," said Carl Spana, Ph.D., President and Chief Executive Officer of Palatin. "We look forward to releasing topline data results from our Phase 2 BMT-801 clinical study of our melanocortin-4 receptor (MC4R) agonist, bremelanotide, plus a glucagon like peptide-1/gastric inhibitory polypeptide (GLP-1/GIP) dual agonist, tirzepatide, in the first quarter of calendar year 2025. Furthermore, we are excited to advance our obesity programs and start multiple clinical trials in 2025 aimed at treating general obesity, weight loss management, and rare MC4R pathway diseases like hypothalamic obesity."

Dr. Spana noted, "We believe focusing on our core and most valuable programs in obesity is the right course of action for the long-term success of Palatin. We have retained an investment bank to conduct, explore, and evaluate strategic options for our non-obesity programs. At this stage, there has been significant interest in and ongoing discussions for our Phase 3 DED program, early-stage glaucoma and retina development programs, and our Phase 2 UC program from multiple parties."

The MC4R pathway plays a key role in the regulation of energy storage and food intake. The novel MC4R selective agonists being developed by Palatin could potentially play a vital role in treating obesity as monotherapy and/or combination therapy.

Fiscal First Quarter Ended September 30, 2024Financial Results

Revenue

Total revenue consists of gross product sales of Vyleesi, net of expenses, allowances and accruals, and license and contract revenue.

Pursuant to the completion of the sale of Vyleesi's worldwide rights for female sexual dysfunction to Cosette Pharmaceuticals for up to $171 millionin December 2023, Palatin did not record any product sales to pharmacy distributors, for the first quarter ended September 30, 2024. For the first quarter ended September 30, 2023, gross product sales were $4.6 millionand net product revenue was $2.1 million.

Operating Expenses

Total operating expenses were $7.8 millionfor the first quarter ended September 30, 2024, compared to $8.2 millionfor the comparable quarter last year. The decrease was mainly the result of the elimination of selling expenses related to Vyleesi offset by greater spending on our MCR programs.

Other (Expense) / Income

Total other (expense) / income, net, consists mainly of foreign currency transaction (loss) and gains and the change in fair value of warrant liabilities, which Palatin had recorded as a liability on the consolidated financial statements, including the revisions of certain prior period amounts to correct a misstatement with respect to classifying warrants as equity instead of a liability. The statement of operations was adjusted each quarter through fiscal year ended June 30, 2024to reflect changes in the fair value of these warrants. For the quarter ended September 30, 2023, Palatin recorded a fair value adjustment gain of $0.7 million.

Cash Flows

Palatin's net cash used in operations for the quarter ended September 30, 2024, was $7.0 million, compared to net cash used in operations of $5.9 millionfor the same period in 2023. The increase in net cash used in operations is mainly due to the increase in the net loss during the period and secondarily to working capital changes.

Net Loss

Palatin's net loss for the quarter ended September 30, 2024, was $7.8 million, or $(0.39)per basic and diluted common share, compared to a net loss of $5.2 million, or $(0.43)per basic and diluted common share, for the same period in 2023.

The increase in net loss for the quarter ended September 30, 2024, over the quarter ended September 30, 2023, was mainly due to the elimination of Vyleesi net product revenue, offset by the elimination of Vyleesi selling expenses and the recognition of the change in fair value of warrant liabilities for the quarter ended September 30, 2023.

Cash Position

As of September 30, 2024, Palatin's cash and cash equivalents were $2.4 million, compared to cash and cash equivalents of $9.5 millionas of June 30, 2024.

Palatin received a scheduled $2.5 milliondeferred upfront payment in November 2024related to the sale of Vyleesi to Cosette Pharmaceuticals.

The Company is actively engaged with multiple potential funding sources for future operating cash needs.

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.

About Palatin

Palatin is a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin receptor systems, with targeted, receptor-specific product candidates for the treatment of diseases with significant unmet medical need and commercial potential.
