METUCHEN, N.J.--(BUSINESS WIRE)--Tevogen Bio today announced TVGN-489, its lead investigational allogeneic SARS-CoV-2 specific Cytotoxic CD8+ T lymphocytes (CTL) immunotherapy for treatment of COVID-19 in high-risk patients, is expected to retain activity against the B.1.1.529, or Omicron variant. A comprehensive review, completed by its preeminent research team, finds the targets of TVGN-489 are not impacted by known Omicron mutations. TVGN-489 is currently undergoing proof of concept clinical trial at Thomas Jefferson University in Philadelphia.
Dr. Neal Flomenberg, M.D., Professor and Chair of the Department of Medical Oncology at Thomas Jefferson University has led the efforts for the development of TVGN-489. “We are deeply concerned about the recently reported Omicron variant’s worrisome immune escape potential and transmissibility. Our research team has reviewed all the mutations present in the Omicron variant and ascertained that TVGN-489’s targets have not been affected. TVGN-489 CTLs are sensitized to multiple targets across the entire viral genome and not simply focused on the spike protein, which, as we’ve unfortunately witnessed, is very susceptible to mutation,” Flomenberg said.
“We performed a similar analysis of the Delta variant when it first appeared. Our targets appeared to be similarly preserved in Delta in that analysis,” Flomenberg continued. “Now, with more than 3400 Delta isolates having been sequenced and added to the NIH/NCBI database, we have seen that TVGN-489’s targets are indeed retained in 98.8% to 100% of these 3400+ isolates. This experience with the Delta variant makes us confident that our analysis of the targets in the Omicron variant will similarly hold up over time," he added.
“We hope to provide a meaningful tool in the fight against COVID-19, particularly for those high-risk patients who may be susceptible to reduced neutralization activity of both vaccine-induced and monoclonal antibody conveyed immunity in Omicron, Delta, and other current variants,” said Tevogen CEO Ryan Saadi, M.D., M.P.H. “While SARS-COV-2 variants have demonstrated how this virus is able to escape our immune system by mutating immunodominant epitopes, the proprietary approach to manufacturing TVGN-489 allows us to monitor the sequences of emerging variants and, if necessary, be able to adjust or fine ‘tune’ our products to ensure that they continue to recognize and treat current and future variants of this and other viruses.”
TVGN-489 is a highly purified SARS-CoV-2 specific cytotoxic CD8+ T lymphocyte product which detects targets spread across the entire viral genome. These targeted CTLs are expected to recognize and kill off virally infected cells, allowing the body to replace them with healthy uninfected cells. TVGN-489 has demonstrated strong antiviral activity against SARS-CoV-2 in preclinical studies.
