Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	Palatin Technologies, Inc. (“Palatin” or the “Company”) is a specialized biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin and natriuretic peptide receptor systems. The Company’s product candidates are targeted, receptor-specific therapeutics for the treatment of diseases with significant unmet medical need and commercial potential. Melanocortin Receptor System. The melanocortin receptor (“MCr”) system is hormone driven, with effects on food intake, metabolism, sexual function, inflammation and immune system responses. 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 significant pharmacological effects. The Company’s lead product, Vyleesi™, was approved by the U.S. Food and Drug Administration (“FDA”) in June 2019, and is being marketed in North America by AMAG Pharmaceuticals, Inc. (“AMAG”) for the treatment of hypoactive sexual desire disorder (“HSDD”) in premenopausal women. The Company’s new product development activities focus primarily on MC1r agonists, with potential to treat inflammatory and autoimmune diseases such as dry eye disease, which is also known as keratoconjunctivitis sicca, uveitis, diabetic retinopathy and inflammatory bowel disease. The Company believes that the MC1r agonist peptides in development have broad anti-inflammatory effects and appear to utilize mechanisms engaged by the endogenous melanocortin system in regulation of the immune system and resolution of inflammatory responses. The Company is also developing peptides that are active at more than one melanocortin receptor, and MC4r peptide and small molecule agonists with potential utility in obesity and metabolic-related disorders, including rare disease and orphan indications. Natriuretic Peptide Receptor System. The natriuretic peptide receptor (“NPR”) system regulates cardiovascular functions, and therapeutic agents modulating this system have potential to treat cardiovascular and fibrotic diseases. The Company has designed and is developing potential NPR candidate drugs selective for one or more different natriuretic peptide receptors, including natriuretic peptide receptor-A (“NPR-A”), natriuretic peptide receptor B (“NPR-B”), and natriuretic peptide receptor C (“NPR-C”).
Business Risk and Liquidity	Since inception, the Company has incurred negative cash flows from operations, and has expended, and expects to continue to expend, substantial funds to complete its planned product development efforts. As shown in the accompanying consolidated financial statements, the Company had an accumulated deficit as of June 30, 2019 of $295,772,879. Income for fiscal 2019 and fiscal 2018 was based on the achieving development milestones. The Company has not yet earned revenue from the commercialization of Vyleesi. The Company anticipates incurring significant expenses in the future as a result of spending on its development programs and will require substantial additional financing or revenues to continue to fund its planned developmental activities. To achieve sustained profitability, if ever, the Company, alone or with others, must successfully develop and commercialize its technologies and proposed products, conduct successful preclinical studies and clinical trials, obtain required regulatory approvals and successfully manufacture and market such technologies and proposed products. The time required to reach sustained profitability is highly uncertain, and the Company may never be able to achieve profitability on a sustained basis, if at all. As of June 30, 2019, the Company’s cash and cash equivalents were $43,510,422, accounts receivable were $60,265,970 and current liabilities were $4,185,892. Management intends to utilize existing capital resources for general corporate purposes and working capital, including, preclinical and clinical development of the Company’s MC1r and MC4r peptide programs and natriuretic peptide program, and development of other portfolio products. Management believes that the Company’s existing capital resources will be adequate to fund the Company’s planned operations through at least September 30, 2020. The Company will need additional funding to complete required clinical trials for its other product candidates and, assuming those clinical trials are successful, as to which there can be no assurance, to complete submission of required applications to the FDA. If the Company is unable to obtain approval or otherwise advance in the FDA approval process, the Company’s ability to sustain its operations could be materially adversely affected. The Company may seek the additional capital necessary to fund its operations through public or private equity offerings, collaboration agreements, debt financings or licensing arrangements. Additional capital that is required by the Company may not be available on reasonable terms, or at all.
Concentrations	Concentrations in the Company’s assets and operations subject it to certain related risks. Financial instruments that subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are primarily invested in one money market account sponsored by a large financial institution. For the year ended June 30, 2019, the Company reported $60,300,476 in license and contract revenue related to a license agreement with AMAG for Vyleesi for North America (“AMAG License Agreement”) (Note 4). For the year ended June 30, 2018, the Company reported $62,134,758 in license and contract revenue related to the AMAG License Agreement. In addition, for the year ended June 30, 2018, the Company reported $5,000,000 in license revenue related to a license agreement with Shanghai Fosun Pharmaceutical Industrial Development Co. Ltd. (“Fosun”) for Vyleesi for China and certain other Asian territories (“Fosun License Agreement”) (Note 5). For the year ended June 30, 2017, the Company reported $44,723,827 in contract revenue related to the AMAG License Agreement.
