Ocean Biomedical (NASDAQ: OCEA) Congratulates JV Partner, Virion Therapeutics, on Promising First-Ever Human Phase 1B Clinical Safety Data for Their Lead Checkpoint Modifier-Containing Immunotherapy for HBV Functional Cure, at Global APASL

Ocean Biomedical, Inc. (

NASDAQ:

 OCEA), a biopharma company working to accelerate the development of compelling discoveries from top research scientists, today congratulates its JV partner Virion Therapeutics, LLC, a clinical-stage biotechnology company developing 

novel T cell-based immunotherapies,

on its 

late breaker oral presentation

 highlighting the 

first-ever human data

from its novel checkpoint modifier immunotherapy for HBV functional cure (VRON-0200), at the 

33

rd

Annual Meeting of APASL

 (The Asian Pacific Association for the Study of the Liver), taking place in Kyoto, Japan from March 27 - 31.

The late breaker Phase 1 data presented today, Virion APASL 2024 Clinical Late Breaker , which includes Virion’s first checkpoint modifier, glycoprotein D (gD), demonstrated that VRON-0200 was safe and well tolerated, with no clinical or laboratory changes of concern, following a single intramuscular of 10 chronically HBV-infected patients, representing 641 patient safety days. “These first ever data for a checkpoint modifier containing T cell vaccine of any kind, represent a critical first step towards our goal of bringing a safe, well tolerated, and easy to administer interferon-sparing immunotherapy to HBV-infected patients worldwide,” said Virion’s CEO, Dr. Andrew Luber. Luber added, “VRON-0200 is our lead clinical program and these clinical safety data will further support our proprietary platform technologies and other pipeline programs in development, including VRON-0300, which is for patients with advanced solid tumors.”

Unlike monoclonal antibody checkpoint inhibitors which attempt to “rescue” already activated, but exhausted CD8+ T cells, checkpoint modifiers alter T cell activation to amplify and broaden a patient’s own immune response – this may include regions of a tumor or infectious disease that are not normally stimulated during a chronic disease, thereby potentially producing a “new” immune response. In addition, after an intramuscular injection, checkpoint modifiers act locally, at the injection site, and not throughout the body, thereby limiting the risk for serious adverse events such as those seen following the intravenous administration of monoclonal antibody checkpoint inhibitors. The clinical safety of this novel mechanism of action, via checkpoint modification, are supported by the these first data presented at APASL.

Ocean Biomedical co-founder and Executive Chairman Dr. Chirinjeev Kathuria, commented: “We congratulate Virion for the first-ever clinical data presented for their checkpoint modifier immunotherapy and these initial results showing it can be administered simply, and safely, to chronically HBV-infected patients. Treatments for chronic HBV are in high demand and could capture an estimated global market of $6.5+ billion by 2032. Checkpoint modification, to alter T cell activation and improve immune responses, is a highly innovative approach and an exciting new technology with a wide array of potential uses for both cancer and chronic infectious diseases. These safety data are another major milestone for our JV partner, Virion, and we look forward to seeing additional safety, and immunological data, at an upcoming meeting. Ocean is pleased to partner with Virion in bringing this technology to patients worldwide and we look forward to helping accelerate this, and other programs, in development.”

About Chronic Hepatitis B

Despite a preventative vaccine, cases of chronic hepatitis B (HBV) continue to rise, with an estimated 296 million persons infected worldwide and 820,000 deaths per year from HBV-related liver complications. This includes almost 100 million persons in China who are affected by this disease. Chronic HBV remains a global health issue with a high unmet medical need since there is no cure available. The current standard of care requires lifelong antiviral therapy to maintain control of the virus.

About VRON-0200

VRON-0200 is a therapeutic immunotherapy, administered by intramuscular injection, designed with the goal of providing a functional cure for chronic HBV infection. While the virus itself stimulates HBV-specific CD8+ T cells, for those patients that can’t clear the initial infection, their T cells soon become exhausted, placing limits on their ability to proliferate and control the virus. Preclinical data support the hypothesis that VRON-0200, through checkpoint modification, can amplify, broaden, and enhance T cell responses which may include T cells that are not normally activated during a chronic HBV infection, which results in improved viral control.

About Virion Therapeutics (Virion)

Virion Therapeutics, LLC is a clinical-stage company developing novel T cell-based immunotherapies to cure cancer and chronic infectious diseases that utilize proprietary genetically encoded checkpoint modifiers to enhance and broaden CD8+ T cell responses to a tumor or chronic infection. Founded in early 2018, Virion has since developed a robust pipeline, including its lead VRON-0200 clinical program, and several additional IND-enabling programs, including its VRON-0300 oncology program for advanced solid tumors, leveraging its proprietary platform technologies. In early Fall 2023, Virion and Ocean Biomedical entered a joint venture to accelerate and expand Virion’s pipeline of novel immunotherapies.
