INOVIO Doses First Participant in Phase 2 Trial for its DNA Vaccine Against Middle East Respiratory Syndrome (MERS), a Coronavirus Disease

Rhea-AI Summary

INOVIO (NASDAQ: INO) has commenced Phase 2 trials for INO-4700, a DNA vaccine aimed at combating the Middle East Respiratory Syndrome (MERS). This multi-center study, involving around 500 healthy volunteers in Jordan and Lebanon, seeks to assess the safety and immunogenicity of the vaccine. The trial builds on promising results from a previous Phase 1 trial, where 98% of participants developed an immune response. Funded by a $56 million CEPI grant, INOVIO aims to provide a preventive vaccine against MERS, a deadly disease with a high fatality rate.

• First participant dosed in Phase 2 trial for MERS vaccine INO-4700.
• Phase 1 trial showed 98% of subjects generated immune responses.
• Funded by a $56 million grant from CEPI, ensuring financial backing.

Negative

• None.

PLYMOUTH MEETING, Pa., Aug. 4, 2021 /PRNewswire/ -- INOVIO (NASDAQ: INO), a biotechnology company bringing to market precisely designed DNA medicines to treat and protect people from infectious diseases, cancer, and HPV-associated diseases, today announced that the company has dosed the first Phase 2 trial subject in its quest to develop the first vaccine against the Middle East Respiratory Syndrome (MERS). INOVIO's Phase 2 trial is designed to evaluate INO-4700, its DNA vaccine candidate for the prevention of MERS, a disease in the coronavirus family for which there are no approved vaccines.

The multi-center Phase 2 trial is a randomized, double-blinded, placebo-controlled study designed to evaluate the safety, tolerability, and immunogenicity of INO-4700 administered with INOVIO's smart device, the CELLECTRA^® 2000, in approximately 500 healthy adult volunteers. The study, which is sponsored by INOVIO and fully funded by the Coalition for Epidemic Preparedness Innovations (CEPI), is being conducted at sites in Jordan and Lebanon where MERS cases have been reported.

This trial builds on the positive results of the Phase 1 trial, which were published in a peer-reviewed article in The Lancet Infectious Diseases entitled, "Safety and immunogenicity of an anti-Middle East respiratory syndrome coronavirus DNA vaccine: A phase 1, open-label, single-arm, dose-escalation trial." Results from this first-in-human Phase 1 trial found high levels of binding antibodies in 92% (57 of 62) of evaluated subjects. Significant antigen-specific cytotoxic T-lymphocyte (CTL) responses were also observed. Importantly, 98% (61 of 62) of vaccinated subjects generated an antibody and/or T cell response against the MERS vaccine.

Dr. J. Joseph Kim, President and CEO of INOVIO, said, "We are pleased to collaborate with CEPI to combat one of the most virulent pathogens of the coronavirus family for which there is no approved vaccine. This advancement not only complements our late-stage efforts with COVID-19, but it also represents an important milestone for INOVIO's infectious disease platform. We look forward to continuing our collaboration with CEPI and moving another step closer to providing patients with a safe and effective preventive vaccine against MERS."

INOVIO's pursuit of a MERS vaccine is funded by a previously announced $56 million grant from CEPI under which INOVIO is advancing two vaccine candidates through Phase 2 field trials against MERS and Lassa fever, respectively. INOVIO and CEPI plan to make a stockpile of these vaccines available for emergency use as soon as possible following Phase 2 testing.

Richard Hatchett, CEO of CEPI, said, "I'm delighted to see the progress made by INOVIO in its MERS vaccine program. As we've seen with COVID-19, coronaviruses pose a significant threat to global health. Prior to the COVID-19 pandemic, CEPI had identified the MERS coronavirus, in particular, as an epidemic threat and partnered with INOVIO in 2018 to advance its promising vaccine candidate. This Phase 2 trial is the first of its kind to assess a vaccine candidate against MERS and represents an important step towards combatting this deadly coronavirus."

Despite the continuing threat of MERS outbreaks, there are no licensed vaccines or treatments for MERS. Since the virus was first identified in Saudi Arabia in 2012, the World Health Organization has reported more than 2,500 people with MERS disease globally and approximately 34% of those patients died. Twenty-seven countries have reported cases, including Korea where an outbreak in the summer of 2015 resulted in 186 cases with 20% dying. In contrast, the case-fatality ratio for COVID-19 before population vaccination was approximately 0.3% to 0.5%; while the case-fatality ratio for the 2003 SARS epidemic was 10%. MERS causes a rapidly progressive respiratory illness that may require intensive care treatment and mechanical ventilation in many patients.

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 3,000 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.

About INOVIO

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 met primary and secondary endpoints for all evaluable subjects in REVEAL 1, in the first of two Phase 3 trials for precancerous cervical dysplasia, demonstrating ability to destroy and clear both high-grade cervical lesions and the underlying high-risk HPV 16 and 18. INOVIO is also evaluating INO-4800, a DNA vaccine candidate against COVID-19, in a Phase 2 clinical trial in the U.S., as well as Phase 2 trials in China and South Korea.
