Tevogen Bio Highlights Promising Trial Data as CEO Leads Patient Advocacy at Capitol Hill, Pledging to Leverage Multi-Billion Dollar Company Assets to Combat Long COVID and Spearhead a New Wave of Medical Innovation

• The primary study endpoints were related to safety. No dose-limiting toxicities or significant adverse events related to TVGN 489, including Cytokine Release Syndrome, were observed in any patient at any dose level. 
• Endpoints measuring the reduction of viral load and the presence of cellular and humoral anti-COVID-19 responses after treatment were met.
• Fifty percent (50%) of treatment arm patients were immunocompromised versus six percent (6%) of observational arm patients.
• Treatment arm patients were infected by a variety of SARS-CoV-2 variants ranging from Delta through Omicron BA.5.2.
• Observational arm patients were treated with standard of care including monoclonal antibodies.
• Key observational findings: All treatment arm patients returned to their baseline level of health within 14 days of treatment. No evidence of COVID reinfection or Long COVID was observed in any treated patient at the time of the six (6) month follow up.

WARREN, N.J., Oct. 08, 2024 (GLOBE NEWSWIRE) — Tevogen Bio (“Tevogen” or “Tevogen Bio Holdings Inc.”) (Nasdaq: TVGN), a clinical-stage specialty immunotherapy biotech developing off-the-shelf, genetically unmodified T cell therapeutics to treat infectious disease and cancers, today reissues its previously announced topline results from its Proof-of-Concept (POC) clinical trial designed to evaluate the safety and feasibility of TVGN 489, the company’s first clinical product utilizing the internally developed ExacTcell™ technology, for the treatment of acute high-risk SARS-CoV-2 patients. TVGN 489 is a genetically unmodified, off-the-shelf, allogeneic cytotoxic CD8+ T lymphocyte (CTL) product with precise targets across the SARS-CoV-2 genome, not just the Spike protein. To date, TVGN 489 targets, identified early in the pandemic, persist in the most recent SARS-CoV-2 variants. The open label comparative trial was conducted at Thomas Jefferson University Hospital in Philadelphia to assess the safety and feasibility of TVGN 489 when given at one of four escalating doses. Twelve ambulatory patients with newly diagnosed SARS-CoV-2 infection who were at higher risk for infection-related complications due to advanced age or CDC-defined comorbid conditions such as heart, lung, liver, and kidney disease, hypertension, diabetes, cancer, or obesity were treated on the trial. Eighteen patients, who also met these criteria but did not receive TVGN 489 because of lack of HLA matching, were enrolled on an observational arm in the study and treated with standard of care including monoclonal antibodies. 

The treated patients had between 2 to 5 comorbidities each and 6 out of 12 (50%) were immunocompromised due to treatment for cancer or autoimmune disease. Multiple SARS-CoV-2 variants were detected in the group. Safety endpoints included infusion reactions, grade 4 adverse events, GVHD, marrow aplasia, neurotoxicity and CRS. 

Table 1. Treatment arm (n=12)

Safety Criteria as Defined in the Study Protocol	Trial Result
Infusion Reactions (≥ Grade 3)	0/12
Cytokine release syndrome, (Grade ≥ 2)	0/12
Neurotoxicity (Grade ≥ 2)	0/12
Graft versus Host Disease	0/12
Grade ≥4 Adverse Events (Related to the CTL therapy & outside the spectrum of identified COVID related adverse events)	0/12

Safety endpoints were reviewed after each dose level and confirmed by an independent Data and Safety Monitoring Committee at Jefferson and by both internal and external Medical Monitors who provided permission to escalate to the next dose level. Based on the data in Table 1, safety was confirmed with the minimum required number of patients per dosing level. In addition to safety endpoints, endpoints measuring the reduction of viral load and the presence of cellular and humoral anti-SARS-CoV-2 responses after treatment were also met.

Enrollment was completed in nine months, and six-month follow-up for all patients concluded on January 19, 2023. In the treatment arm, no patient experienced progression of their SARS-CoV-2 infection and all patients returned to their baseline level of health within 14 days of treatment. There were no incidences of COVID-19 reinfection or Long COVID observed in any treated patient through the 6-month follow-up period. While patients in the treatment group experienced COVID-19 symptom relief in a rapid, consistent timeframe as self-reported and confirmed by the investigators, patients on the observation arm showed improvement in a less consistent, and in some cases, longer time frame.   

The study results were published in Blood Advances, a peer-reviewed journal in August of this year.

“The highly encouraging data of TVGN 489 allows us to turn our attention to the continuing critical unmet need for subsets of the population in the SARS-CoV-2 landscape, such as the elderly, those with Long COVID, and patients who are immunocompromised,” said Dr. Dolores Grosso, DNP, the Principal Investigator of the trial.

Sten Vermund, MD, PhD, Professor of Public Health at Yale University, President of the Global Virus Network, and chair of the Chairperson of Tevogen Bio’s Innovation and Public Health Advisory Board notes that “Immunocompromised individuals, many of whom do not respond to COVID-19 vaccinations, remain at significant risk for severe outcomes from SARS-CoV-2 infections. CTL therapy offers a promising treatment option for this vulnerable group. Preventing prolonged SARS-CoV-2 infections in immunocompromised patients not only improves their health and enables them to resume critical treatments like cancer therapy, but also benefits the wider public. It is within this population that SARS-CoV-2 mutations and resistance to antiviral medications have been observed to develop.”

“Tevogen’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. In 2022, Tevogen Bio was recognized as the highest-valued biotech unicorn, with an independent valuation of $4.2 billion. With the successful completion of this clinical trial and a robust portfolio of assets, I expect the company’s updated valuation, to be reported in the coming days, to show a substantial increase,” said Tevogen founder and CEO Nobel Peace Prize nominee Dr. Ryan Saadi, MD, MPH.
