Palatin Technologies Announces Notification of Patent Allowance On Melanocortin Receptor-Specific Peptides for Sexual Dysfunction

CRANBURY, N.J., May 2, 2013 /PRNewswire/ — Palatin Technologies, Inc. (NYSE MKT: PTN), a biopharmaceutical company developing targeted, receptor-specific peptide therapeutics for the treatment of diseases with significant unmet medical need and commercial potential, announced today that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for U.S. Patent Application Serial Number 12/952,238 (the ‘238 application).  The application includes composition of matter claims on a new class of melanocortin receptor- specific peptides for sexual dysfunction and other indications.

The ‘238 application is the first patent application to issue covering a novel family of melanocortin-4 receptor agonist peptides.  The melanocortin-4 receptor mediates sexual response, and agonists have been studied for treatment of both erectile dysfunction and female sexual dysfunction.  Palatin’s bremelanotide product, a melanocortin-4 receptor agonist peptide drug administered using an autoinjector, has recently completed Phase 2 human studies for female sexual dysfunction, with pivotal Phase 3 clinical studies scheduled to start later this year.

The peptides in the ‘238 application demonstrated effects on sexual function in animal models.  Palatin is evaluating these peptides as potential follow-on or second generation products for treatment of sexual dysfunction.  The melanocortin-4 receptor also has potential utility in treatment of obesity, metabolic syndrome and other indications.

“As we move into Phase 3 with bremelanotide for female sexual dysfunction, we are pleased to have new peptides with improved profiles suitable for use as second generation products,” stated Carl Spana, Ph.D., President and CEO of Palatin.

A Notice of Allowance is issued after the USPTO makes a determination that a patent can be granted from an application. The issued patent twenty-year term will not expire until June 2029, and is subject to a patent term adjustment, or extension, of 464 days.  The Notice of Allowance for the ‘238 application has been posted on the USPTO public PAIR website.
