Providence, RI, Aug. 01, 2023 (GLOBE NEWSWIRE) -- On World Lung Cancer Day, Ocean Biomedical, Inc. (NASDAQ: OCEA) is sharing details of its multi-pronged Lung Cancer Program built on novel immunotherapy discoveries by Scientific Co-founder Dr. Jack A. Elias. He and his team have revealed that Chitinase 3-like-1 (CHi3L1) is a master regulator that inhibits antitumor immune responses. Ocean Biomedical’s lung cancer program is advancing several approaches to reversing immune system suppression caused by CHi3L1 alone and in combination with other immunotherapy pathways. These programs suppress primary and metastatic tumor growth in multiple animal models and have potential use in multiple forms of visceral cancers. In recent studies, Ocean Biomedical’s programs have demonstrated up to
Anti-CHi3L1 monoclonal immunotherapy. The first step in this tumor reduction approach has stemmed from effectively reversing immune system suppression through binding CHi3L1 polypeptides with Ocean Biomedical’s proprietary immunoglobulin antibody. This monoclonal approach has yielded dramatic reduction in mouse lung tumor burden similar to current, cutting-edge monoclonal therapeutics (imaging below), creating the possibility of a new cancer immunotherapy option for patients who have poor response to existing treatments. Ocean’s monoclonal antibody targeting CHi3L1 was awarded a U.S. patent in June 2023 not only for application in lung cancer, but potential application in prostate cancer, colon cancer, rectal cancer, ovarian cancer, kidney cancer, breast cancer, glioblastoma, and melanoma as well.
Multiple Bispecific Immunotherapy Pathways. Building on the monoclonal antibody approach, Ocean Biomedical is developing groundbreaking bispecific antibodies that target CHi3L1 in combination with other known suppressors of tumor growth and development. This approach results in the simultaneous targeting of several major cancer pathways. Each bispecific candidate has been shown to substantially multiply effectiveness compared to current, established mono-focused immuno-therapeutics. This novel approach builds on one of the most exciting developments in cancer research in recent years - the realization that evasion of the body’s immune system is essential for tumor growth, progression, and resistance to treatments, especially through the suppression of T-cell responses and the stimulation of natural immune checkpoints. These advances have led to some successful lung cancer therapeutics that target PD1, PDL1, and CTLA-4, which individually all have roles in suppressing the immune system.
Ocean Biomedical is working to create a new generation of cancer therapeutics. In separate new approaches targeting PD1 and CTLA4, each in combination with anti-CHi3L1, the company’s bispecific therapeutic candidates have created lung cancer tumor suppression of 85%–
Anti-CHi3L1+Anti-PD1 bispecific immunotherapy. One of the currently effective cancer immunotherapies targets Programmed Cell Death Receptors, often designated “PD1” and its ligand “PDL1.” In results of one study testing the efficacy of the monospecific and bispecific antibodies by culturing tumor cells and human T lymphocyte cells together in the presence of varying combinations of our antibodies (results illustrated below), anti-PD1 caused the T cells to kill approximately
Anti-CHi3L1+Anti-CTLA4 bispecific immunotherapy. In addition to the PD1 pathway, Ocean Biomedical is also targeting the immune checkpoint inhibitor CTLA4, another established immunotherapy pathway. The efficacy of these monospecific and bispecific antibodies has been tested in mouse model experiments (results shown below), where malignant melanoma tumor cells are released into the mouse circulation and their ability to spread (metastasize) to the lung is evaluated by quantitating the black pleural tumor colonies that develop in the presence of varying combinations of Ocean’s antibodies. Shown below, anti-CTLA4 decreased tumor metastasis by approximately
Multiple Pathways, Multiple Cancers. On several fronts, Ocean Biomedical is advancing lung cancer treatment candidates that have the ability to target multiple tumor suppressing pathways at the same time, and early indications show potential for multiplying the effectiveness of current immuno-oncology products, generating surprising, synergistic outcomes. Because these candidates are building on evolving understanding of how cancer cells subvert and attenuate natural immune responses, each candidate has potential application against a broad range of cancers. In a recently published independent study, the anti-CHi3L1 monoclonal has shown effectiveness in controlling some of the most harmful pathways in the universally lethal brain cancer, glioblastoma. In total, Ocean Biomedical’s oncology platform has garnered 27 issued or pending patents, already covering ‘method of use’ in nine unique cancers, including prostate cancer, colon cancer, rectal cancer, ovarian cancer, kidney cancer, breast cancer, glioblastoma, melanoma, and lung cancer.
“We are making discoveries that we believe will drive cancer research, and eventually treatment and patient outcomes, forward,” said Dr. Elias. “This pathway discovery is an unprecedented leap, because if you control CHi3L1, you don’t just control one anti-cancer pathway, you simultaneously control many anti-cancer pathways.”
“On World Lung Cancer Day, we are proud to be part of the global effort to cure this terrible disease,” commented Ocean Biomedical’s CEO, Elizabeth Ng. We are working on the systematic steps needed to progress the anti-CHi3L1 antibodies into the clinic to potentially become impactful new cancer therapeutics.”
“Non-Small Cell Lung Cancer alone affects nearly 500,000 people in the U.S.,“ commented Dr. Chirinjeev Kathuria, Ocean Biomedical’s co-founder and Executive Chairman. “These discoveries have the potential to save thousands of lives of people affected not just by lung metastasis, and glioblastoma, but also other forms of cancer such as breast, prostate and melanoma.”

About Cancer Immunotherapy
Immunotherapy is an evolving approach to cancer therapeutics that enhances traditional treatments by activating a person’s own immune system to fight cancer. Immunotherapy can boost the immune system to find and attack cancer cells. Monoclonal antibodies are immune system proteins created to bind to specific targets on cancer cells or cells in the tumor growth environment. Ocean Biomedical’s monoclonal antibody targets a polypeptide (CHi3L1) that is associated with accelerated tumor growth in a wide range of cancers. By suppressing CHi3L1, Ocean Biomedical has been able to suppress primary and metastatic tumor growth in multiple animal models. As reflected in the newly issued patent, this unique immunotherapy approach has potential use in multiple forms of visceral cancers.
