INOVIO (NASDAQ:INO) and GeneOne Life Science (KSE:011000) today announced interim data through week 16 from a Phase 1/2a trial of DNA vaccine INO-4700 (also called GLS-5300) for MERS coronavirus (MERS-CoV).
| PLYMOUTH MEETING, Pa. and SEOUL, South Korea, April 28, 2020 /PRNewswire/ -- INOVIO (NASDAQ:INO) and GeneOne Life Science (KSE:011000) today announced interim data through week 16 from a Phase 1/2a trial of DNA vaccine INO-4700 (also called GLS-5300) for MERS coronavirus (MERS-CoV). Vaccine recipients demonstrated strong antibody and T cell immune responses after 2 or 3 doses with 0.6 mg of INO-4700, a DNA vaccine that targets the MERS-CoV Spike (S) glycoprotein, delivered with intradermal CELLECTRA® device. The vaccination regimen was well-tolerated with no vaccine-associated severe adverse events (SAEs). The researchers at the Wistar Institute, Seoul National University Hospital, and the International Vaccine Institute (IVI) collaborated on this study with funding from IVI. These results were selected for an oral presentation at the American Society of Gene & Cell Therapy (ASGCT) Conference to be held virtually from May 12-15, 2020. Dr. J. Joseph Kim, INOVIO’s President & CEO, said, “The INO-4700 Phase 1/2a clinical trial data demonstrates that our MERS DNA vaccine is able to generate robust immune responses using INOVIO’s intradermal CELLECTRA delivery system. This exciting data provides a great foundation for the ongoing COVID-19 vaccine advancement as it demonstrates the power of INOVIO’s delivery system and the strength of our coronavirus experience. As we have designed our COVID-19 vaccine INO-4800 using the same strategy as INO-4700, including the selection of full length Spike protein as the target and the use of intradermal CELLECTRA device, we are hopeful that the ongoing Phase 1 clinical trial with INO-4800 would generate similar clinical immune responses and safety data as we have just reported for INO-4700.” Overall, for those receiving 0.6 mg of INO-4700, 88% demonstrated seroconversion after a 2 dose regimen at 0 and 8 weeks, while for those receiving a 3 dose regimen given at 0, 4 and 12 weeks, 84% seroverted after 2 doses and 100% after 3 doses, as measured by a binding antibody assay against the full-length S protein (ELISA). Additionally, 92% of the vaccine recipients in both groups displayed the ability to neutralize the virus using a neutralization assay (EMC2012-Vero neutralization). Robust T cell responses were observed in 60% of vaccine recipients after the 2 dose regimen and 84% of those in the 3 dose group (ELISpot assay). Interestingly, a single dose of 0.6 mg of INO-4700 intradermal vaccination resulted in 74% binding antibody response rate and 48% neutralization antibody response rate. Dr. Jerome Kim, Director General of IVI, said, “IVI is pleased to join partners in reporting these findings as a result of our collaboration in the world’s first vaccine candidate against MERS. These and subsequent clinical trials could pave the way for accelerated development of a DNA vaccine against MERS.” This is the 2nd study of INO-4700 (GLS-5300) in a clinical trial, the first being a 75-person study (MERS-001) of vaccine administered intramuscularly and followed by electroporation at either 0.67, 2 or 6 mg. Notably in the MERS-001 study, there was no significant difference between dose levels and vaccine induced immune responses were similar to those seen in recovered patients following natural infection (Lancet Infectious Disease, 2019). INO-4700 vaccination has previously been shown to provide 100% protection against MERS virus disease in a pathogenic monkey challenge model. INOVIO is planning to advance INO-4700 into a Phase 2 clinical trial in the Middle East with a previously announced funding of $56 million by the Coalition for Epidemic Preparedness Innovations (CEPI). About INOVIO’s Global Coalition Advancing INO-4800 INOVIO has assembled a global coalition of collaborators, partners and funders to rapidly advance INO-4800. R&D collaborators to date include the Wistar Institute, the University of Pennsylvania, Université Laval, and the University of Texas. INOVIO has partnered with Beijing Advaccine and the International Vaccine Institute to advance clinical trials of INO-4800 in China and South Korea, respectively. INOVIO is also assessing preclinical efficacy of INO-4800 in several animal challenge models with Public Health England (PHE) and Commonwealth Scientific and Industrial Research Organization (CSIRO) in Australia. INOVIO is also working with a team of contract manufacturers including VGXI, Inc., Richter-Helm, and Ology Biosciences to produce one million doses of INO-4800 by year-end and seeking additional external funding and partnerships to scale up the manufacturing capacities to satisfy the urgent global demand for a safe and effective vaccine. To date, CEPI, the Bill & Melinda Gates Foundation, and the US Department of Defense have contributed significant funding to the advancement and manufacturing of INO-4800. About INO-4800 INO-4800 is INOVIO’s DNA vaccine candidate created to protect against the novel coronavirus SARS-CoV-2, which causes COVID-19. INO-4800 was designed using INOVIO’s proprietary DNA medicine platform rapidly after the publication of the genetic sequence of the coronavirus that causes COVID-19. INOVIO has deep experience working with coronaviruses and is the only company with a Phase 2a vaccine for a related coronavirus that causes Middle East Respiratory Syndrome (MERS). 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). 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 demonstrated in clinical trials. With more than 2,000 patients receiving INOVIO investigational DNA medicines in more than 6,000 applications across a range of clinical trials, INOVIO has a strong track record of rapidly generating DNA medicine candidates to meet urgent global health needs.
