Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Operations	Organization and Operations Inovio Pharmaceuticals, Inc. (the “Company” or “INOVIO”), is a biotechnology company focused on bringing to market precisely designed DNA medicines and vaccines to help protect people from infectious diseases, including COVID-19, and to help treat people with cancer and conditions associated with human papillomavirus ("HPV"). INOVIO has shown in clinical trials that its DNA vaccine candidates can be delivered into cells in the body via a proprietary smart device allowing the nucleic-acid delivered gene products to activate functional T cell and antibody responses against targeted pathogens and cancers. The Company's DNA medicines pipeline is comprised of three types of product candidates: prophylactic DNA vaccines, therapeutic DNA immunotherapies, and DNA encoded monoclonal and bispecific antibodies ("dMAbs" and “dBTAs”), all of which utilize the two components of INOVIO's integrated platform, SynCon® and CELLECTRA®. The Company's proprietary SynCon® technology creates precisely designed plasmids, which are circular strands of DNA that instruct a cell to produce proteins or antigens to help the person’s immune system respond with antibodies and immune cells which recognize and then help block viruses and destroy cancerous or pre-cancerous cells. INOVIO's patented CELLECTRA® proprietary smart device facilitate uptake of its DNA medicines into the cell, which has been a key limitation of historical DNA-based technology approaches. Human clinical trial data from more than 15,000 administrations across more than 5,000 participants to date have shown a tolerable safety profile. INOVIO's corporate strategy is to develop, seek regulatory approval for and commercialize its novel DNA medicines to address unmet global health needs. The Company continues to advance and clinically validate an array of DNA medicine candidates that target infectious diseases, such as COVID-19, as well as HPV-associated diseases and cancer. The Company's partners and collaborators include ApolloBio Corporation, AstraZeneca, Advaccine Biopharmaceuticals Suzhou Co., The Bill & Melinda Gates Foundation (Gates), Coalition for Epidemic Preparedness Innovations ("CEPI"), The U.S. Department of Defense ("DoD"), Defense Advanced Research Projects Agency ("DARPA"), HIV Vaccines Trial Network, the U.S. Defense Threat Reduction Agency’s Medical CBRN Defense Consortium ("MCDC"), International Vaccine Institute ("IVI"), Kaneka Eurogentec, National Cancer Institute, National Institutes of Health, National Institute of Allergy and Infectious Diseases, Ology Bioservices, the Parker Institute for Cancer Immunotherapy, Plumbline Life Sciences, Regeneron Pharmaceuticals, Inc., Richter-Helm BioLogics, Thermo Fisher Scientific, the University of Pennsylvania, the Walter Reed Army Institute of Research and The Wistar Institute. The Company and its collaborators are currently evaluating the feasibility of, or conducting or planning clinical studies of DNA medicines for COVID-19 as a heterologous booster vaccine candidate; Middle East Respiratory Syndrome, or MERS; Lassa fever; Ebola; as well as HPV-associated precancers, including cervical, vulvar, and anal dysplasia; HPV-associated cancers, including head & neck; other HPV-associated disorders, such as recurrent respiratory papillomatosis, or RRP; glioblastoma multiforme, or GBM; and prostate cancer. INOVIO was incorporated in Delaware in June 2001 and has its principal executive offices in Plymouth Meeting, Pennsylvania.
