Palatin Technologies, Inc. is a biopharmaceutical company. The Company is engaged in developing targeted, receptor-specific peptide therapeutics for the treatment of diseases with significant unmet medical need and commercial potential. Its programs are based on molecules that modulate the activity of the melanocortin and natriuretic peptide receptor systems. The Company's primary product in clinical development is bremelanotide for the treatment of premenopausal women with hypoactive sexual desire disorder (HSDD), which is a type of female sexual dysfunction (FSD) defined as low desire with associated distress. Its other drug development programs include Melanocortin receptor-4 (MC4r), PL-3994 and Melanocortin receptor-1 (MC1r). MC4r is a compound used for treatment of obesity and diabetes. PL-3994 is a subcutaneously injected guanylate-cyclase type A (GC-A) receptor agonist. MC1r agonist peptides are used for treatment of inflammatory and dermatologic disease indications.
