Nature of Operations [Abstract]
Nature of Operations	Note 1 – Nature of Operations PDS Biotechnology Corporation, a Delaware corporation (the “Company,” “PDS,” or the “combined company”), PDS is a clinical-stage immunotherapy company developing a growing pipeline of cancer immunotherapies and infectious disease vaccines designed to overcome the well-established limitations of current immunotherapy technologies. PDS owns Versamune^®, a proprietary T-cell activating platform designed to train the immune system to better attack and destroy disease. When paired with an antigen, which is a disease-related protein that is recognizable by the immune system, Versamune^® has been shown to induce, in vivo, large quantities of high-quality, highly potent polyfunctional CD8+ killer T-cells, a specific sub-type of CD8+ killer T-cell that is more effective at killing infected or target cells. Our immuno-oncology products can potentially be used as a component of combination products with other leading technologies to provide effective treatments across a range of cancer types, including Human Papillomavirus (HPV)-based cancers, melanoma, colorectal, lung, breast and prostate cancers or as monotherapies in early-stage disease. PDS is working to expand its infectious disease pandemic development program, which includes novel vaccines for COVID-19 and universal influenza, in addition to its previously announced tuberculosis development collaboration with Farmacore Biotechnology. From the Company’s inception, it has devoted substantially all of its efforts to drug development, business planning, engaging regulatory, manufacturing and other technical consultants, acquiring operating assets, planning and executing clinical trials and raising capital. On March 15, 2019, the Company, then operating as Edge Therapeutics, Inc. (“Edge”), completed its reverse merger with privately held PDS Biotechnology Corporation (“Private PDS”), pursuant to and in accordance with the terms of the Agreement and Plan of Merger (the “Merger Agreement”), dated as of November 23, 2018, as amended on January 24, 2019, by and among the Company, Echos Merger Sub, a wholly-owned subsidiary of the Company (“Merger Sub”), and Private PDS, whereby Private PDS merged with and into Merger Sub, with Private PDS surviving as the Company’s wholly-owned subsidiary (the “Merger”). In connection with and immediately following completion of the Merger, the Company effected a 1-for-20 reverse stock split (the “Reverse Stock Split”) and changed its corporate name from Edge Therapeutics, Inc. to PDS Biotechnology Corporation, and Private PDS changed its name to PDS Operating Corporation. For accounting purposes, the Merger was treated as a “reverse acquisition” under generally accepted accounting principles in the United States (“U.S. GAAP”) and Private PDS is considered the accounting acquirer. Accordingly, upon consummation of the Merger, the historical financial statements of Private PDS became the Company’s historical financial statements, and the historical financial statements of Private PDS are included in the comparative prior periods. See “Note 4 – Reverse Merger” for more information on the Merger. As part of the Merger, the Company acquired all of Edge’s assets relating to current and future research and development. In December 2019, a novel (new) coronavirus known as SARS-CoV-2 was first detected in Wuhan, Hubei Province, People’s Republic of China, causing outbreaks of the coronavirus disease, known as COVID-19, that has now spread globally. On January 30, 2020 the World Health Organization (WHO) declared COVID-19 a public health emergency. The Secretary of Health and Human Services declared a public health emergency on January 31, 2020, under section 319 of the Public Health Service Act (42 U.S.C. 247d), in response to the COVID-19 outbreak. On March 11, 2020, the WHO declared COVID-19 a pandemic. The full impact of the COVID-19 pandemic is unknown and rapidly evolving. The COVID-19 pandemic has and could continue to negatively affect the Company’s liquidity and operations. To date, two of the three recently initiated PDS0101 clinical trials have been delayed, specifically as a result of the adverse impact the COVID-19 pandemic has had on clinical trial operations for cancer indications in the United States. Even though both of these studies have since been initiated despite the pandemic challenges, the evolving COVID-19 pandemic has also impacted the pace of enrollment in clinical trials and we may be affected by similar delays as patients may avoid or may not be able to travel to healthcare facilities and physicians’ offices unless due to a health emergency and clinical trial staff can no longer get to the clinic.
