Heat Biologics Highlights Importance of T cell Immunity to Prevent COVID-19
White paper highlights potential of Heat's vaccine to boost T cell immunity, alone or in combination with other vaccines
DURHAM, NC / ACCESSWIRE / August 5, 2020 / Heat Biologics, Inc. ("Heat") (NASDAQ:HTBX), a clinical-stage biopharmaceutical company focused on developing first-in-class therapies to modulate the immune system, including multiple oncology product candidates and a novel COVID-19 vaccine product candidate, today highlighted the importance of T cell immunity in preventing COVID-19 in a white paper released today. Heat's COVID-19 vaccine is being designed to generate robust T cell immunity against SARS-CoV-2, the virus responsible for COVID-19. To read the full white paper, please visit: www.heatbio.com/product-pipeline/scientific-publications.
Key highlights of the white paper include:
- Published studies evaluating patients that have recovered from SARS-CoV-2 infection demonstrate that antibody responses to the virus are fleeting, suggesting that current vaccine approaches that generate a predominantly antibody response may fall short in generating a durable and protective immune response
- Studies from the current COVID-19 pandemic and past studies from patients recovered from the related SARS and MERS outbreak demonstrate the reliance on T cell responses, where CD4 T cells are often required to generate effective antibody responses, and "killer" CD8 T cells may be required to destroy virus infected cells before the virus can replicate
- An ideal vaccine against SARS-Cov-2 should activate multiple arms of the immune system, including innate, humoral (antibodies), and cellular immunity (T cells)
- Heat's COVID-19 vaccine is designed to drive T cell immunity, while also activating antibody responses and innate immunity, which may complement conventional COVID-19 vaccines in combination approaches by enhancing T cell immunity, while contributing to innate immunity and antibody generation, especially in the more vulnerable aged population and/or those with comorbidities
Jeff Wolf, CEO of Heat Biologics, commented, "Our COVID-19 vaccine platform is designed to drive predominantly T cell immunity-in contrast to most of the conventional approaches in clinical development, which focus on antibody immunity. We are designing our vaccine to be used as either a standalone vaccine, or as a prime and boost combination with other vaccines under development, to drive robust T cell immunity and bolster antibody responses, especially in high-risk populations with a compromised immune response. Our confidence is further bolstered by the latest pre-clinical studies demonstrating immunogenicity proof-of-concept. We look forward to advancing our unique vaccine towards human clinical trials."
