- INO-4201 found to be well-tolerated in the trial
- Humoral responses were boosted in 100% (36 of 36) of treated participants
PLYMOUTH MEETING, PA, USA I February 2, 2023 I INOVIO (NASDAQ:INO), a biotechnology company focused on developing and commercializing DNA medicines to help treat and protect people from HPV-associated diseases, cancer, and infectious diseases, today announced positive results from a Phase 1b clinical trial evaluating INO-4201, a DNA vaccine candidate, as a booster in healthy adult participants who previously received a single injection of Ervebo. In the trial, INO-4201 was well-tolerated and boosted humoral responses in 100% (36 of 36) of treated participants.
INO-4201 was evaluated in a 46-participant randomized, placebo-controlled Phase 1b trial (NCT04906629) to assess its safety, tolerability, and immunogenicity in healthy adult participants who previously received a single injection of Ervebo, a vaccine approved by the U.S. Food and Drug Administration for the prevention of disease caused by Zaire ebolavirus in individuals 18 years of age and older. The participants were dosed with 1 mg of INO-4201 injected intradermally followed by electroporation using our investigational proprietary smart device, CELLECTRA®. The trial was designed to test whether INO-4201 can be used as a booster in healthy participants previously vaccinated with Ervebo. The trial was spearheaded by Global Urgent and Advanced Research and Development (GuardRX), sponsored by Geneva University Hospitals, and funded by the U.S. Defense Advanced Research Projects Agency (DARPA).
Dr. Angela Huttner, MD, Infectious Disease Consultant, Geneva University Hospitals, and the lead investigator of the study, said, “INO-4201 was well-tolerated and all treated participants responded to the booster vaccine. These are encouraging results since our participants were initially vaccinated with Ervebo three to seven years ago. We remain grateful to our participants for their critical role in the development of this vaccine candidate, which we hope will be a key player in future Ebola Virus Disease prevention.”
Dr. Gary Kobinger, microbiologist, GuardRX ex-officio (President) and Board Member and Director of the Galveston National Laboratory at the University of Texas Medical Branch, said, “We are particularly pleased with INO-4201’s boost effect on neutralizing titers. To our knowledge, this is one of the highest responses we have ever seen across multiple vaccine platforms. Indeed, our results showed that the neutralizing titers were significantly higher in the individuals who received the INO-4201 boost compared to the placebo and the response was maintained even 24 weeks later.”
Dr. Laurent Humeau, PhD, INOVIO’s Chief Scientific Officer, said, “We are very encouraged by today’s data, which demonstrates the versatility of our platform and reinforces our belief in DNA medicines’ ability to elicit immune responses across multiple indications, from HPV-associated tumors to infectious diseases. We also believe DNA medicines’ ability to be readministered can be an important factor in a booster. We thank our collaborators, DARPA, GuardRX, and the University of Geneva, for conducting the trial and we look forward to the data being published in a peer-reviewed journal.”
About INO-4201
INO-4201 is a DNA vaccine targeting Zaire Ebola virus (ZEBOV) glycoprotein (GP), designed to prevent ZEBOV infection. INO-4201 encodes for a synthetic consensus antigen that encompasses ZEBOV genetic variability from various outbreak strains to broaden immune coverage for divergent ZEBOV virus variants.
About Ebola Virus Disease
The Ebola virus family includes four virus species that cause periodic outbreaks of a highly contagious and lethal human infectious disease – called Ebola Virus Disease (EVD). The virus is transmitted from wild animals to people then easily spreads via human-to-human transmission. Disturbingly, new research suggests dormant Ebola virus in a previously infected survivor could re-emerge up to nearly 5 years later and again allow human-to-human transmission [Keita et al Nature (Sept. 15, 2021)]. Ebola virus is classified as a Category A Priority Pathogen by the U.S. Centers for Disease Control and Prevention (CDC). This designation indicates a national security risk, and the U.S. FDA has an accelerated development approval pathway for vaccines against such pathogens. Also, the World Health Organization (WHO) continues to list Ebola Virus Disease as a priority for research and development in emergency contexts and coordinates planning to prevent and respond to Ebola epidemics.

About GuardRX
Established in 2018, GuardRX executes preclinical and clinical development strategies on prophylactic and therapeutic products for neglected diseases. GUARD is a non-profit, non-governmental organization whose goal is to bring prophylactic and therapeutic products that do not have a traditional commercialization pathway. GUARD is committed to facilitating the availability of lifesaving products to the global community including in the event of an infectious disease emergency. GUARD expertise includes preclinical and clinical development of vaccines and therapeutics, regulatory submissions and production of cGMP material; humoral immune responses evaluation using tailored sensitive plate-based ELISA; establish & standardize new diagnostics protocols; submission to appropriate regulatory agencies for Therapeutic Products and Institutional Review Boards (IRBs); production of study final reports, and award data management.
GUARD’s main objective is to accumulate clinical data packages within rigorous regulatory processes to support further clinical progression or long-term solutions to orphan diseases for the betterment of the global population. For more information, visit www.guardrx.org.
