New York, NY, June 29, 2023 (GLOBE NEWSWIRE) -- Tevogen Bio Inc, a clinical-stage specialty immunotherapy biotech pioneer developing off-the-shelf, genetically unmodified T cell therapeutics in virology, oncology, and neurology, and Semper Paratus Acquisition Corporation, a publicly traded special purpose acquisition company, today announced the execution of a merger agreement (the “Merger Agreement”). Upon closing of the merger (the “Transaction”), the combined company will be named Tevogen Bio Holdings Inc. (“Tevogen Holdings”). Tevogen Holdings common stock and warrants are expected to be listed on the NYSE under the new ticker symbol “TVGN”.

Tevogen Bio is currently focused on developing its pipeline using its precision T cell platform, ExacTcell. ExacTcell is a product development toolkit that utilizes CD8+ Cytotoxic T Lymphocytes (“CTLs”), also known as Killer T Cells, one of nature’s most powerful weapons against cancer and infection. Unlike currently available genetically engineered T cell therapies, the ExacTcell approach is based on careful selection of naturally occurring T cells that recognize targets of interest from the body’s native T cell receptor pool and is designed to provide enhanced safety. CD8+ CTLs in ExacTcell-based products also target multiple and distinct antigens to overcome potential mutational challenges. 

Tevogen Bio’s lead product is TVGN 489, an allogeneic, genetically unmodified T cell therapy for the treatment of COVID-19 in highly vulnerable patient populations, such as the immune-compromised, elderly, and infirm, along with potential applications in Long COVID treatment and prevention. Tevogen Bio has completed a proof-of-concept clinical trial for TVGN 489, showing positive results, including no dose-limiting toxicities or significant adverse events related to TVGN 489 observed in any patient at any dose level. TVGN 489 has not been observed to be compromised by any COVID-19 variant to date.

Upon completion of the Transaction, Tevogen Bio will be pursuing several late-stage clinical trials, expanding manufacturing capacity, and expediting the development of products targeting life-threatening viral infections, several viral-induced and non-viral-induced common cancers, and multiple sclerosis.

Tevogen Bio’s founder and CEO, Dr. Ryan Saadi said, “Tevogen Bio’s goal is to provide access to the vast and unprecedented potential of personalized immunotherapies for large patient populations impacted by common cancers and viral infections. To truly steer towards success in this sector, a highly refined business acumen must seamlessly combine with an intimate understanding of human health, its implications for all other sectors of the economy, and the far-reaching effects on society at large.”

Suren Ajjarapu, CEO of Semper Paratus commented, “We are thrilled to team up with Tevogen Bio, a biopharma company at the cutting-edge of immunotherapy, and look forward to a partnership for long-term expansion and innovation. Tevogen Bio’s rapid growth from concept to a fully operational biotech company in less than 24 months is the result of ambitious goals and well-executed strategies by its highly motivated and skilled team of experts. We look forward to supporting Tevogen Bio’s patient-centric mission to develop convenient and accessible immunotherapies for large patient populations while continuing the expansion of its new-era biotech business that integrates affordability with business sustainability.” 

Leadership Team

Following the closing of the Transaction, Dr. Ryan Saadi, MD, MPH, will serve as the CEO and Chairman of the Board of Directors of Tevogen Holdings. The Board of Directors of Tevogen Holdings is also expected to include Professor Curtis Patton, Susan Podlogar, Victor Sordillo, Lindee Goh, Suren Ajjarapu, and Jeffrey Feike.

Transaction Overview

The Transaction was unanimously approved by the boards of directors of all parties, at an expected combined pro forma enterprise value of approximately $1.2 billion. In connection with the Transaction, Semper Paratus will migrate out of the Cayman Islands, domesticate as a Delaware corporation, and rename itself Tevogen Bio Holdings Inc., and Tevogen Bio will merge with and into a newly formed wholly owned subsidiary of Tevogen Holdings. Additionally, the Transaction includes a contingent earnout in the form of additional equity in Tevogen Holdings payable to the Tevogen Bio stockholders and Semper Paratus’ sponsor.
