Nature of Operations [Abstract]
Nature of Operations	Note 1 – Nature of Operations PDS Biotechnology Corporation, a Delaware corporation (the “Company” or “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. We believe our product candidates are of interest for potential in relation to Human Papillomavirus, or HPV,- associated 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. 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, 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. 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 and on March 13 the President declared a national emergency in response to the 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 were 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. The FDA issued and since updated guidance to assist sponsors in assuring the safety of trial participants, maintaining compliance with Good Clinical Practice (GCP) and minimizing risks to trial integrity. Clinical trial sites have implemented institution-specific measures securing the safety of patients and staff to ensure the integrity of the trials in the face of the ongoing pandemic. All three studies have since been initiated despite the pandemic challenges; however, the evolving COVID-19 pandemic has impacted the pace of enrollment in clinical trials in general and we may be negatively affected with our trials. COVID-19 related travel and other restrictions may also impact the potential for on-site monitoring visiting and audits and inspections by us, third parties, and regulators. There may be shortages of site personnel and equipment necessary for the timely completion of our trials. We are providing support to address these challenges, but these mitigation measures may not overcome the obstacles that the pandemic has wrought which continue to impede progress of clinical trials. Although there is uncertainty related to the anticipated impact of the COVID-19 pandemic on our future results, we believe our current cash reserves, leave us well-positioned to manage our business through this crisis as it continues to unfold. However, the impacts of the COVID-19 pandemic are broad-reaching and continuing and the financial impacts associated with the COVID-19 pandemic are still uncertain. Despite the economic uncertainty resulting from the COVID-19 pandemic, we intend to continue to focus on the development of our product candidates and we have expanded our infectious disease pipeline since the pandemic brought renewed resources and interest in technologies such as the Versamune® platform in the context of research and development in prevention of COVID-19. We are working with a consortium of partners in Brazil to develop PDS0203; a vaccine for the prevention of COVID-19. This consortium received a commitment from the Secretary for Research and Scientific Training of The Ministry of Science, Technology and Innovation of Brazil to fund up to approximately US$60 million to support the clinical development and commercialization of a Versamune®-based COVID-19 vaccine in Brazil.
