CRANBURY, N.J., May 15, 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 financial results for its fiscal third quarter ended March 31, 2024.

"Study results of our successful Phase 3 MELODY-1 clinical trial for DED demonstrate that PL9643, with its early onset of efficacy for multiple symptoms and signs of dry eye disease and the excellent ocular safety and tolerability profile, has the potential to be a highly differentiated product," said Carl Spana, Ph.D., President and Chief Executive Officer of Palatin. "The efficacy results were statistically significant for the co-primary symptom endpoint of pain and 7 of 11 exploratory secondary endpoints, including eye dryness, as early as two weeks, which was the first time point measured. We are advancing discussions with potential collaboration partners and actively preparing for a meeting with the FDA later this year to discuss the remaining studies for the PL9643 program required to support an NDA submission."

Dr. Spana further commented, "We are excited to launch two new therapeutic area clinical trials in the second quarter of calendar year 2024, with topline data readouts in the second half of calendar year 2024. The first is a Phase 2 clinical study of a MCR4 agonist plus a GLP-1 in obese patients. The second is a Phase 2 clinical study evaluating bremelanotide co-formulated with a PDE5i, for the treatment of erectile dysfunction in patients that do not respond to PDE5i monotherapy."

Fiscal Third Quarter Ended March 31, 2024 Financial Results

Revenue

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

Pursuant to the completion of the sale of Vyleesi's worldwide rights for female sexual dysfunction to Cosette Pharmaceuticals for up to $171 million in December 2023, Palatin did not record any product sales to pharmacy distributors for the quarter ended March 31, 2024. For the quarter ended March 31, 2023, gross product sales were $3.4 million, with net product revenue of $1.2 million.

Operating Expenses

Total operating expenses were $9.2 million compared to $8.5 million for the comparable quarter last year. The increase was related to greater spending on our MCR programs, offset partially by the elimination of selling expenses related to Vyleesi.

Other Income / (Expense)

Total other income / (expense), net, consists mainly of 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 to reflect changes in the fair value of these warrants. For the quarters ended March 31, 2024, and 2023, Palatin recorded a fair value adjustment gain of $0.4 million and a loss of $1.5 million, respectively.

Warrant Liabilities

Palatin had assessed the impact of improperly classifying the warrants related to the October 2022 financing within equity, rather than as a warrant liability that is adjusted through charges or credits to the statement of operations to reflect changes in the fair value of the warrants, and determined the impact was not material to any prior period impacted. Accordingly, the Company adjusted prior periods as those financial statements are presented for comparative purposes in future filings.

On January 24, 2024, the Company and warrant holders amended the terms of the warrants related to the October 2022 and October 2023 financings. As a result, the $1.9 million of warrant liabilities as of June 30, 2023, was reclassified to additional paid-in capital upon amendment.

Cash Flows

Palatin's net cash used in operations was $8.6 million, compared to net cash used in operations of $1.4 million for the same period last year. The increase is mainly due to changes in working capital.

Net Loss

Palatin's net loss was $8.4 million, or $(0.53) per common share, compared to a net loss of $8.7 million, or $(0.76) per common share for the comparable period last year.

The decrease over the comparable quarter last year was mainly due to a larger operating loss in fiscal 2024 offset by the higher other income primarily from changes in the fair value of warrant liabilities.

Cash Position

As of March 31, 2024, Palatin's cash, cash equivalents and marketable securities were $10.0 million, compared to cash, cash equivalents and marketable securities of $9.5 million plus $2.3 million of accounts receivable, as of December 31, 2023, and $5.5 million plus $1.3 million of accounts receivable, as of September 30, 2023, and cash, cash equivalents and marketable securities of $11.0 million plus $2.9 million of accounts receivable, as of June 30, 2023.

The Company believes that existing cash, cash equivalents, marketable securities and accounts receivable, will be sufficient to fund currently anticipated operating expenses and disbursements into the second half of calendar year 2024.

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, MCR1 through MCR5. 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. Palatin's strategy is to develop products and then form marketing collaborations with industry leaders to maximize their commercial potential.
