PLYMOUTH MEETING, PA – February 23, 2021 – INOVIO (NASDAQ:INO), a biotechnology company focused on bringing to market precisely designed DNA medicines to treat and protect people from infectious diseases and cancer, today announced the first participant was dosed in a Phase 1B clinical trial for INO-4500, its DNA vaccine candidate for Lassa fever, in Ghana. The Phase 1B clinical trial (LSV-002), ongoing at the Noguchi Memorial Institute for Medical Research in Accra, Ghana, is the first vaccine clinical trial for Lassa Fever to be conducted in West Africa, where the infection is endemic. INO-4500 was also the first vaccine candidate for Lassa fever to enter human trials.
INOVIO is advancing INO-4500 with full funding from the Coalition for Epidemic Preparedness Innovations (CEPI), a global partnership that leverages funding from public, private, philanthropic and civil society organizations to support research projects to develop vaccines against emerging infectious diseases. INOVIO previously received a $56 million grant from CEPI in 2018, under which the company is developing vaccine candidates for Lassa Fever and Middle East Respiratory Syndrome (MERS). INOVIO and CEPI are committed to making a vaccine available as soon as possible for emergency use as a stockpile product post-Phase 2 testing.

About INOVIO’s Phase 1B Clinical Trial for INO-4500
INOVIO’s Phase 1B clinical trial, LSV-002, will enroll approximately 220 adult participants who are 18-50 years old, with the primary endpoints of evaluating safety and immunogenicity in an African population. The dosing regimen involves two vaccinations at 0 and 28 days with either 1.0 mg or 2.0 mg dosing levels. In addition to providing valuable insights on the INO-4500 safety and immunogenicity profile, this trial will inform dose selection for subsequent Phase 2 studies in West Africa.
Since its establishment in 1979, the Noguchi Memorial Institute for Medical Research (“The Institute”) has gained global recognition as a leading biomedical research institute in Africa, building capacity for prevention and control of endemic diseases, as well as emerging and re-emerging diseases, in Ghana and the West African sub-region. The Institute has been a leader in developing effective diagnosis capabilities and clinical research for the treatment and protection against HIV/AIDS, H1N1 Pandemic Flu, Lassa fever, Yellow fever, Ebola Virus Disease and malaria. The lead clinical Principal Investigator for LSV-002 is Professor Dr. Kwadwo A. Koram, an expert and specialist in tropical medicines and epidemiologist with more than 20 years of research experience, including malaria vaccines.
About Lassa Fever
Lassa fever is an animal-borne, acute hemorrhagic viral illness primarily observed in parts of West Africa.. Infection is spread through contact with infected rodents, as well as person-to-person transmission via bodily fluids (primarily in health care settings). The disease can cause a range of outcomes, including fever, vomiting, and swelling of the face, pain in the chest, back and abdomen, bleeding of various parts of the body including the eyes and nose and death. Lassa virus infection in West Africa is estimated to affect 100,000 to 300,000 people annually, and is responsible for 10 – 16% of hospital admissions in the region. The virus is responsible for approximately 5,000 deaths annually.
Because of difficulties in diagnosing Lassa fever, the lack of standardized surveillance assays, and the remote nature of many of the areas in West Africa where outbreaks typically occur, the numbers of reported cases and deaths are very likely significantly lower than the actual numbers of cases and deaths. Though the majority (about 80%) of Lassa virus-infected persons are asymptomatic or have mild symptoms, the infection can be quite serious to fatal in others. The case-fatality among patients hospitalized for Lassa fever is about 15 – 20% and, in some epidemics, case-fatality has reached 50% in hospitalized patients. There are no licensed vaccines or treatments specifically for Lassa fever.
About INOVIO’s DNA Medicines Platform
INOVIO has 15 DNA medicine clinical programs currently in development focused on HPV-associated diseases, cancer, and infectious diseases, including coronaviruses associated with MERS and COVID-19 diseases being developed under grants from the Coalition for Epidemic Preparedness Innovations (CEPI) and the U.S. Department of Defense. DNA medicines are composed of optimized DNA plasmids, which are small circles of double-stranded DNA that are synthesized or reorganized by a computer sequencing technology and designed to produce a specific immune response in the body.
INOVIO’s DNA medicines deliver optimized plasmids directly into cells intramuscularly or intradermally using INOVIO’s proprietary hand-held smart device called CELLECTRA®. The CELLECTRA® device uses a brief electrical pulse to reversibly open small pores in the cell to allow the plasmids to enter, overcoming a key limitation of other DNA and other nucleic acid approaches, such as mRNA. Once inside the cell, the DNA plasmids enable the cell to produce the targeted antigen. The antigen is processed naturally in the cell and triggers the desired T cell and antibody mediated immune responses. Administration with the CELLECTRA® device ensures that the DNA medicine is efficiently delivered directly into the body’s cells, where it can go to work to drive an immune response. INOVIO’s DNA medicines do not interfere with or change in any way an individual’s own DNA. The advantages of INOVIO’s DNA medicine platform are how fast DNA medicines can be designed and manufactured; the stability of the products, which do not require freezing in storage and transport; and the robust immune response, safety profile, and tolerability that have been observed in clinical trials.
With more than 2,000 patients receiving INOVIO investigational DNA medicines in more than 7,000 applications across a range of clinical trials, INOVIO has a strong track record of rapidly generating DNA medicine candidates with potential to meet urgent global health needs.
INOVIO is a biotechnology company focused on rapidly bringing to market precisely designed DNA medicines to treat and protect people from infectious diseases, cancer, and diseases associated with HPV. INOVIO is the first and only company to have clinically demonstrated that a DNA medicine can be delivered directly into cells in the body via a proprietary smart device to produce a robust and tolerable immune response. Specifically, INOVIO’s lead candidate VGX-3100, currently in Phase 3 trials for precancerous cervical dysplasia, destroyed and cleared high-risk HPV 16 and 18 in a Phase 2b clinical trial. High-risk HPV is responsible for 70% of cervical cancer, 91% of anal cancer, and 69% of vulvar cancer. Also in development are programs targeting HPV-related cancers and a rare HPV-related disease, recurrent respiratory papillomatosis (RRP); non-HPV-related cancers glioblastoma multiforme (GBM) and prostate cancer; as well as externally funded infectious disease DNA vaccine development programs in Zika, Lassa fever, Ebola, HIV, and coronaviruses associated with MERS and COVID-19 diseases.

CEPI is an innovative partnership between public, private, philanthropic, and civil organizations, launched at Davos in 2017, to develop vaccines to stop future epidemics. CEPI has moved with great urgency and in coordination with WHO in response to the emergence of COVID-19. CEPI has initiated 11 partnerships to develop vaccines against the novel coronavirus. The programs will leverage rapid response platforms already supported by CEPI as well as new partnerships. The aim is to advance COVID-19 vaccine candidates into clinical testing as quickly as possible.
Before the emergence of COVID-19 CEPI’s priority diseases included Ebola virus, Lassa virus, Middle East Respiratory Syndrome coronavirus, Nipah virus, Rift Valley Fever and Chikungunya virus. CEPI also invested in platform technologies that can be used for rapid vaccine and immunoprophylactic development against unknown pathogens (Disease X). Follow our news page for the latest updates.
