Development Overview

Introduction

Middle East respiratory syndrome coronavirus vaccine (INO 4700 also called GLS 5300), a DNA vaccine targeting MERS coronavirus (MERS-CoV) spike S glycoprotein was being developed by GeneOne Life Sciences and Inovio Pharmaceuticals, for the prevention of middle-east respiratory syndrome [MERS] virus infection. The DNA vaccines was being developed by utilising Inovio's ASPIRE™ (Antigen SPecific Immune REsponses) platform. The platform delivers optimised synthetic antigenic genes into cells, to be translated into protein antigens that activate an individual's immune system to generate robust targeted T cell and antibody responses. The vaccine was delivered intradermally using the CELLECTRA® delivery device. Clinical development was underway in Jordan, Lebanon, Kenya and South Korea. However, in November 2022, Inovio Pharmaceuticals announced its decision to discontinue its development as the two-dose regimen of Middle East respiratory syndrome coronavirus vaccine did not meet Coalition for Epidemic Preparedness Innovation's (CEPI) selection criteria for further development.

INOVIO's DNA vaccine deliver optimized plasmids directly into cells intramuscularly or intradermally using INOVIO's proprietary hand-held smart device called CELLECTRA®. CELLECTRA® uses a brief electrical pulse to open small pores in the cell reversibly to allow the plasmids to enter, overcoming a key limitation of other DNA and mRNA approaches. Once inside the cell, the plasmids are used by the cell's own machinery to generate coded antigens, which then stimulate an immune response, thereby strengthening the body's own natural defense mechanisms. Administration with the CELLECTRA device ensures that the DNA medicine is delivered directly into the body's cells, where it can go to work immediately mounting an immune response.

Inovio Pharmaceuticals in-licensed the intellectual property from the University of Pennsylvania. The programme was originally developed by VGX Pharmaceuticals, which was acquired and integrated into Inovio Biomedical, and later renamed Inovio Pharmaceuticals.

Company Agreements

In June 2020, Inovio Pharmaceuticals partnered with International Vaccine Institute and Seoul National University for initiation of phase I/II clinical trial of INO 4800. Earlier IVI and SNU Hospitals also collaborated for phase I/IIa trials for a MERS coronavirus vaccine INO 4700 [1]

In April 2018, Inovio Pharmaceuticals entered into a partnership agreement with Coalition for Epidemic Preparedness Innovations (CEPI) under which, the former will develop vaccine candidates, INO 4500 and INO 4700, against Lassa fever and Middle East Respiratory Syndrome (MERS), respectively, by securing funding of up to $US56 million from the latter, to support Inovio’s preclinical and clinical advancement through phase II of INO 4500 and INO 4700. The funding will support development up to the end of phase II, providing clinical safety and immunological data, and the establishment of investigational stockpiles that will be ready for clinical efficacy trial testing during outbreaks. The two companies intend to make the vaccines available as soon as possible for emergency use. The agreement is expected to fund Inovio’s development efforts over a five-year period and also includes options, not counted in the total above, to establish investigational stockpiles of both vaccines. [2]

Inovio Pharmaceuticals entered into a collaboration with GeneOne Life Science for conducting a phase I trial of the former's DNA vaccine for MERS. Under the terms of the agreement, GeneOne will conduct and fund the study, and in return it will get milestone-based co-ownership of the immunotherapy. Following successful completion of the study, both the companies will seek for a third party for supporting and financing further development and commercialisation of the vaccine [3] .

In November 2015, GeneOne entered into a clinical development agreement with the Walter Reed Army Institute of Research for advancing the development of an MERS vaccine. Under the terms of the agreement, GeneOne and WRAIR will test the GLS 5300 vaccine in a first-in-human phase I clinical study to be executed at the WRAIR’s Clinical Trials Center while WRAIR will be responsible for all relevant MERS vaccine clinical trial procedures and costs at the Walter Reed Army Institute of Research [4] [5] .

Inovio Pharmaceuticals has a licensing agreement with the University of Pennsylvania covering technology and intellectual property for novel DNA vaccines and therapeutics. Inovio has exclusive worldwide rights to develop a number of DNA plasmids and constructs for the treatment and/or prevention of HIV, HCV, HPV and influenza. The original licence agreement was formed in 2007 between VGX Pharmaceuticals and the University [6] . In January 2010, the agreement was expanded to add exclusive worldwide licences for DNA vaccines against pandemic influenza, Chikungunya virus infections and foot-and-mouth disease, and also includes new chemokine and cytokine molecular adjuvant technologies. An amendment was made to the licensing agreement in June 2014 to add global rights to intellectual property and technology for synthetic therapies for the treatment of cancer, infectious diseases including tuberculosis and Middle East respiratory syndrome (MERS), and immune activators. The expanded agreement also includes rights to IL-12 encoded DNA plasmids. Inovio has made upfront and milestone payments to the University of Pennsylvania and the University is eligible for future milestone and royalty payments [7] .

Key Development Milestones

In November 2022, Inovio Pharmaceuticals discontinued the development of Middle East respiratory syndrome coronavirus vaccine following initial analyses of clinical data from phase I and II trials. Data from the trials showed that the two-dose regimen of Middle East respiratory syndrome coronavirus vaccine was well-tolerated and generated positive immune responses, however it did not meet Coalition for Epidemic Preparedness Innovation's (CEPI) selection criteria for further development [8] .

In May 2021, Inovio Pharmaceuticals initiated a phase II trial to evaluate the safety, tolerability and immunogenicity of INO 4700 administered by intradermal (ID) injection followed by electroporation (EP) using the CELLECTRA™ 2000 device in healthy adult volunteers for Middle East Respiratory Syndrome Coronavirus (MERS-CoV) infection (MERS201; NCT04588428). The randomised, double-blind, placebo-controlled trial intends to enrol approximately 542 patients in Kenya, Jordan and Lebanon [9] . In August 2021, Inovio Pharmaceuticals dosed first patient [10] . As of December 2021, the company had completed enrollment of 192 participants for the first part (dose finding stage) of this phase II trial [11] .

In April 2020, GeneOne Life Science and Inovio Pharmaceuticals completed the a phase I/II trial that evaluated the safety, tolerability and immunogenicity of Middle East respiratory syndrome coronavirus vaccine (NCT03721718; MERS-002). Earlier, in September 2017, GeneOne Life Science and Inovio Pharmaceuticals jointly initiated the trial in South Korea, following approval for initiation of the trial by the Korean Ministry of Food and Drug Safety. The open trial enrolled 60 participants in the South Korea [12] [13] . In April 2020, Inovio Pharmaceuticals released interim results from the trial [14] [15] .

In September 2017, GeneOne Life Sciences and Inovio Pharmaceuticals, in collaboration with the Walter Reed Army Institute of Research (WRAIR) completed the phase I trial that evaluated the safety and immunogenicity of GLS 5300 intramuscular, in healthy volunteers (NCT02670187; WRAIR 2274). The open label trial was initiated in January 2016, and enrolled 75 volunteers in the US. In October 2015, GeneOne and Inovio filed an IND application with the FDA to conduct the phase I study, which was subsequently approved in November 2015 [16] [5] [17] [18] . Interim immune response and safety data from the trial were reported in February 2017. Additional data from the trial were released by the company in September 2017 [19] [20] [21] . Updated immuogenicity data from the trial were released by the company in June 2018 [22] .

In November 2013, Inovio reported that preclinical tests of its MERS DNA vaccine produced robust and durable immune responses, demonstrating its potential to prevent and treat this virulent coronavirus infection. Inovio requires external funding to develop this vaccine further [23] . Additional preclinical study results, reported in August 2015, showed that the MERS DNA-vaccine induced 100% protection from a live virus challenge in animals. When administered in mice, camels and monkeys, the vaccine induced a robust immune response capable of preventing the virus from infecting cells. All the vaccinated monkeys in the study were protected from symptoms of MERS disease when challenged with a live MERS virus. The preclinical studies were conducted in collaboration with University of Pennsylvania, Public Health Agency of Canada, National Institutes of Health, University of Washington, and University of South Florida [24] .

In preclinical challenge studies, MERS vaccine protected 100% of vaccinated rhesus macaques from a lethal MERS virus challenge with two doses [12] .

Financing information

As of August 2020, INOVIO Pharmaceuticals received a funding of $US56 million from Coalition for Epidemic Preparedness Innovations (CEPI) for the planned phase II trial that will begin in the middle east later this year [25] .

The International Vaccine Institute (IVI) is funding a trial [see above] [15] which is evaluating an intradermal formulation of GLS 5300 against the MERS virus. IVI will provide full financial assistance for the trial by utilising a $US34 million grant that Samsung Foundation had committed to IVI in 2015 for the development of a MERS vaccine [19] .

Scientific Summary

Adverse Events

Interim results from the phase I trial demonstrated that the vaccine was well tolerated and no significant safety concerns were noted to date [20] [18] .

Interim data through week 16 from a phase I/IIa trial showed that middle East respiratory syndrome coronavirus vaccine was well-tolerated and no vaccine-associated severe adverse events were observed in the trial [14] [15] .

Immunogenicity

Summary

Updated data from a phase I trial demonstrated that antibody responses by ELISA in 94% of subjects at week 14 (two weeks post-third dose). Also, broad-based t cell responses were observed in 88% of participants. No statistically significant dose-dependent differences in antibody response rates (91%, 95%, and 95% at doses of 0.67, 2, and 6 mg, respectively) were reported. Durable antibody responses to the vaccine were also maintained through 60 weeks following dosing. Earlier results demonstrated that after a three dose vaccine regimen with GLS 5300 intramuscular, high levels of binding antibodies were measured in 92% (57 of 62) of evaluated subjects. Earlier reported interim results showed that single or two doses of the vaccine generated a robust antibody response in 84% or 44% of evaluated participants, respectively. Significant antigen-specific cytotoxic T-lymphocyte (CTL) responses were observed and 98% of subjects generated an antibody and/or T cell response against the MERS vaccine. Results were presented from the 75 healthy volunteers [26] [22] [19] [20] [18] [10] .

Interim results through week 16 from the phase I/IIa trial showed strong antibody and T cell immune responses after 2 or 3 doses with 0.6 mg of middle East respiratory syndrome coronavirus vaccine. 100% binding and 92% neutralizing antibody responses against MERS-CoV was observed. Seroconversion after a 2 dose regimen at 0 and 8 weeks was observed in 88% of patients, as compared to 84% and 100% seroconversion after 2 doses and 3 doses respectively in patients receiving a 3 dose regimen given at 0, 4 and 12 weeks. Additionally, 92% of the vaccine recipients in both groups displayed the ability to neutralize the virus using a neutralization assay. 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. A binding antibody response rate of 74% and neutralization antibody response rate of 48% was demonstrated by a single dose of 0.6 mg of middle east respiratory syndrome coronavirus vaccine intradermal vaccination [14] [15] .

A DNA vaccine construct targeting multiple Middle Eastern respiratory syndrome (MERS) coronavirus antigens was immunogenic and seroconversion was observed in mice. The antibodies generated in 100% of the mice (n = 20) were able neutralise the MERS virus infection; unvaccinated mice (n = 10) did not produce neutralising antibodies. The vaccine also elicited a robust and broad T cell response in mice, producing CD8+ and CD4+ T cells responses against multiple epitopes of the MERS spike protein [23] .

The DNA-based MERS vaccine when administered in mice, camels and monkeys, induced a robust immune response capable of preventing the virus from infecting cells [24] .
