On March 30, 2022 Anixa Biosciences, Inc. (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer and infectious diseases, reported the initiation of a Phase 1 trial evaluating its novel chimeric antigen receptor T-cell (CAR-T) therapy in ovarian cancer (Press release, Anixa Biosciences, MAR 30, 2022, View Source [SID1234611211]). The CAR-T approach used for Anixa’s therapy is known as chimeric endocrine receptor T-cell (CER-T) since the target of the engineered T-cells is an endocrine receptor. The Phase 1 trial at Moffitt Cancer Center will evaluate the safety and efficacy of Anixa’s therapy in patients with ovarian cancer. Anixa holds an exclusive, worldwide license for the technology, which was developed at the Wistar Institute.

While CAR-T therapy has shown efficacy in some hematological tumors, reproducing the same results with solid tumors, such as ovarian cancer, has proven challenging. One of the reasons for this difficulty is that effective CAR-T therapy needs a specific antigen to recognize that is only present on target cancer cells in order to avoid negatively affecting healthy cells. The CER-T therapy being evaluated in Anixa’s Phase 1 study differs from traditional CAR-T in that it targets the follicle stimulating hormone receptor (FSHR), which research indicates is exclusively expressed on ovarian cells in healthy adult females.

"We are thrilled to have partnered with world-class scientists at Moffitt Cancer Center to advance our CER-T platform and feel that this partnership provides a critical opportunity to make a significant impact on the treatment of solid tumors," said Dr. Amit Kumar, President, CEO and Chairman of Anixa Biosciences. "We strongly believe that our unique targeting approach differentiates our CER-T platform from traditional CAR-T approaches and that CER-T has potential to work in solid tumors where other therapies have failed."

Jose R. Conejo-Garcia, M.D., Ph.D., Chair of the Department of Immunology at Moffitt Cancer Center and co-inventor of the CER-T technology, added, "CAR-T therapies are rapidly becoming an important player in cancer therapy, and our lab has developed a technology that has the potential to target tumors by using an existing biological mechanism that is well understood. If our CER-T approach is successful, it could serve as a model for future targeted CAR-T therapies in other cancer types. The goal in cancer therapy has always been to kill cancer cells with limited damage to healthy tissue, and we look forward to seeing how this CER-T therapy may be able to accomplish that in solid tumors, which have historically proven challenging to eradicate with cell therapy."

Robert Wenham, M.D., MS, FACOG, FACS, the trial’s lead investigator and Chair of the Department of Gynecologic Oncology at Moffitt Cancer Center, added, "There are limited treatment options for recurrent, chemo-resistant ovarian cancer, and this platform holds immense promise to change that. I am hopeful that this program represents a unique opportunity for us to potentially make a truly game-changing impact for patients with ovarian cancer and other solid tumors."

About Anixa’s CER-T Approach (Follicle Stimulating Hormone Receptor-Mediated CAR-T technology)
Anixa’s chimeric antigen receptor T-cell (CAR-T) technology approach is an autologous cell therapy comprised of engineered T-cells that target the follicle stimulating hormone receptor (FSHR). FSHR is found at immunologically relevant levels exclusively on the granulosa cells of the ovaries. Since the target is a hormone (chimeric endocrine) receptor, and the target-binding domain is derived from its natural ligand, this technology is known as CER-T (chimeric endocrine receptor T-cell) therapy, a new type of CAR-T.
