Voltron Therapeutics, Inc.’s Scientific Co-Founder Dr. Mark C. Poznansky has Guest Essay Published in the New York Times 

The Vaccines We Have Are Good. But They Could Be So Much Better

NEW YORK, July 19, 2021 (GLOBE NEWSWIRE) – Voltron Therapeutics, Inc. today announced that the Company’s Scientific Co-Founder, Dr. Mark C. Poznansky’s guest essay titled “The Vaccines We Have Are Good. But They Could Be So Much Better”, was published in the New York Times on June 10, 2021. 

Dr. Mark C. Poznansky serves as Director of the Vaccine and Immunotherapy Center (VIC) and Physician at Massachusetts General Hospital and an Associate Professor of Medicine at Harvard Medical School. Dr. Poznansky also serves as a scientific founder for Voltron Therapeutics, helping to advise on the early clinical research and implementation of testing in the clinical setting among other things. 

In the essay, Dr. Poznansky and his colleague Dr. Michael V. Callahan discuss the impressive, ongoing efforts to get a safe, effective vaccine broadly into the population, as well as the remaining need for new vaccines that address the evolution of variants that can overcome the immunity provided by existing COVID-19 vaccines and/or prior infections. 

As a Scientific Co-Founder of Voltron Therapeutics, Dr. Poznansky has been instrumental in the development of HaloVax™, a Self-Assembling Vaccine (SAV) against COVID-19.  HaloVax may not only prevent disease, but may offer safe administration with a strong, broad immune response, specifically designed to be applicable to emerging viral targets, such as COVID-19 and its variants. Importantly, HaloVax™ is designed with safety as its top priority to avoid known vaccine adverse effects, including excessive local response or inappropriate immune response. Other vaccine approaches, in many cases, simply provoke the immune system to target an aspect of the COVID-19 virus, namely the spike protein, and then only as it appeared in the original pandemic outbreak in 2019. HaloVax is a flexible system for evoking a broad range of immune responses against a virus – simultaneously training the immune system to target several proteins contained with the virus that can be readily modified to rapidly address newly evolving variants.  The need for second generation vaccine platforms like HaloVax is increasing, given the rise of the Delta variant and the inevitable rise of further variants that are evolving to evade the first-generation vaccines.  

The vaccine is built on a base of a heat shock protein (HSP70)-Avidin fusion protein that activates the cellular component of the immune system; this is different from most other vaccine efforts, which have used adjuvants such as alum. The second portion of the vaccine consists of virus targeting peptides derived from our understanding of the COVID-19 structure, which are bound to the heat shock protein via Biotin. This enables rapid iteration and up-to-date, data informed, changes in the peptide sequences to enable swift production and accommodate potential changes in the pathogen itself. The selected immunogenic peptides complete the customized COVID-19 vaccine. 

Voltron Therapeutics previously announced positive data from its second set of preclinical animal testing of its COVID-19 vaccine. This study investigated an updated peptide construct, based on initial testing as well as recent scientific developments, in order to identify the best balance of immune responses for prevention of this pandemic pathogen.  

The study consisted of a full near GLP preclinical mouse study evaluating whether the self- assembling vaccine, consisting of the immune activating MTBhsp70-Avidin component and antigen targeting biotinylated immunogenic peptides, increased the immune response relative to controls or peptides alone. 

Results demonstrated that the self-assembling vaccine construct did indeed significantly increase both helper and cytotoxic T cell responses to the vaccine targeted antigens compared to controls. This proof of concept for the SAV platform is critical to the COVID-19 program, additional infectious disease targets as well as the oncology applications of this cutting-edge technology.  HaloVax is being developed in conjunction with Hoth Therapeutics, Inc (NASDAQ: HOTH). 

“We remain optimistic that our recent successful preclinical testing will rapidly lead to clinical trials in humans and bring us closer to a safe, broad acting, effective, and durable vaccine to help prevent disease caused by COVID-19 and future variants. Our discovery and operating teams have placed us on the cutting edge of vaccine development, leveraging our platform technology to create vaccines in a more rapid and adaptable manner,” said Pat Gallagher, Chief Executive Officer, Voltron Therapeutics, Inc.
