Cell Therapy Company Tevogen Bio Holdings Inc. Prepares to Launch Crucial Genetic Predisposition Study in Preparation to Investigate the Potential of TVGN 489 to Address Critical Unmet Need for Long COVID Treatment

Tevogen Bio Holdings Inc. ('Tevogen Bio') (Nasdaq: TVGN)

• Tevogen’s ExacTcell platform was developed to harness the killing ability of naturally occurring cytotoxic T lymphocytes (CTLs), against viral and malignant targets.
• TVGN 489, a CTL therapy produced by the ExactTcell platform, contains CTLs recognizing multiple protein targets across the SARS-CoV-2 genome. These cells were well tolerated in a completed proof of concept clinical trial in high-risk patients with acute COVID-19, with later stage studies planned in this area.
• Tevogen plans to assess whether TVGN 489 cells can rapidly eliminate symptoms of Long Covid. To facilitate the development of a Long Covid treatment trial, Tevogen will launch a preliminary study in Q1 2024 to assess whether the development of Long COVID is associated with a key component of an individual’s immune system known as Human Leukocyte Antigens (HLA).
• TVGN 489 CTLs work in conjunction with HLA molecules to recognize and destroy viral targets. HLA types vary from person to person and are known to influence degrees of risk in other infectious settings. Specific HLA types may be associated with more or less protection against a particular infection.

Prior to launching the Long COVID clinical trial, Tevogen seeks to address whether Long COVID occurs more commonly with certain HLA types and less commonly with others, or whether Long COVID occurs randomly in the population regardless of HLA. This effort will help Tevogen generate CTL products recognizing the HLA types that are most commonly associated with Long Covid, if a relationship between Long Covid and HLA type is identified, with the goal of allowing a Long COVID treatment trial to be designed and completed expeditiously.

“We have spent significant resources and time identifying TVGN 489’s targets from across the entire COVID genome. These have remained remarkably durable over the last 4 and a half years. I am highly optimistic that TVGN 489 will offer a meaningful solution for both acute and Long COVID patients,” said Neal Flomenberg, MD, Tevogen’s Chief Scientific Officer.

“Generating this information will provide important insights into the immunologic factors that contribute to Long COVID development and will greatly facilitate the treatment trial we expect to follow,” added Shannon Rudolph, Clinical Scientist at Tevogen
