Tevogen Bio Announces Positive Safety Results Upon Completion of Patient Enrollment in Proof-of-Concept Clinical Trial of T cell Therapy for Elderly or High-Risk COVID-19 Patients

• No dose-limiting toxicities or significant treatment-related adverse events were observed for any patient at any dose level

Tevogen Bio, a late stage clinical biotechnology company specializing in the development of cell and gene therapies in oncology, neurology, and virology, today announced that it completed enrollment in the Proof-of-Concept clinical trial of the company’s lead investigational product, TVGN-489, for elderly or high-risk ambulatory COVID-19 patients.

TVGN-489 is a genetically unmodified, off-the-shelf, allogeneic cytotoxic CD8+ T lymphocyte (CTL) product with activity against multiple, precise targets across the SARS-CoV-2 genome. The open-label clinical trial was designed to study the safety and optimal dose of TVGN-489 when given to ambulatory patients with newly diagnosed COVID-19 infection who were at higher risk for infection-related complications. Patients are considered high risk due to comorbid conditions such as heart, lung, liver, and kidney diseases, hypertension, diabetes, cancer, obesity or older age (≥ 65 years) with or without comorbid conditions. The study was conducted at Thomas Jefferson University Hospital in Philadelphia.

Patients received one of four escalating dose levels, with enrollment completed for all levels in nine months. Patients treated earlier in the trial were infected with the Delta variant of COVID-19, with subsequent patients having Omicron and its subvariants of COVID-19. No dose-limiting toxicities or significant treatment-related adverse events, including Cytokine Release Syndrome (CRS), were observed for any patient at any dose level.

“Concluding patient enrollment in this trial is an exciting milestone and I believe a promising step forward in the advancement of potential new treatments for high risk patients with COVID-19,” said Principal Investigator of the trial, Dolores Grosso, DNP, CRNP, of Jefferson University Hospitals.

“Completing this trial will allow us to proceed quickly with further testing of this product in a variety of additional patient groups, including those suffering from Long COVID,” said Tevogen’s Chief Scientific Officer, Neal Flomenberg, M.D.

"We are extremely pleased to report the successful completion of patient enrollment in the TVGN-489 Proof-of-Concept clinical trial and are incredibly grateful for the trial patients, research and development team, investigators, as well as our partners at Thomas Jefferson University Hospital for completing this clinical trial. We are looking forward to full review of the data in the coming weeks,” said Tevogen CEO Ryan Saadi, M.D., M.P.H.
