Breast cancer vaccine (Anixa Biosciences/Cleveland Clinic)

Vaccine Was Safe and Well Tolerated at the Maximum Tolerated Dose Results Support Advancement of the Program into Phase 2 Development Combination of Keytruda® and the vaccine generated T cell responses and showed no major additional side effects, supporting plans for a Phase 2 neoadjuvant combination study in newly diagnosed breast cancer patients SAN JOSE, Calif., Dec. 11, 2025 /PRNewswire/ -- Anixa Biosciences, Inc. ("Anixa" or the "Company") (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer, today announced the presentation of final data from the Phase 1 clinical trial of its investigational breast cancer vaccine (NCT04674306) at the 2025 San Antonio Breast Cancer Symposium (SABCS). The trial was conducted in collaboration with Cleveland Clinic and funded by a grant from the U.S. Department of Defense. Final Phase 1 findings showed the investigational vaccine met all major primary endpoints, was safe and well tolerated at the maximum tolerated dose (MTD), and elicited protocol-defined immune responses in 74% of participants. The presentation, titled "Final Results of a Phase I Trial of Alpha-lactalbumin (aLA) Vaccine for Breast Cancer," was delivered by Justin Johnson, Ph.D., Program Manager at Cleveland Clinic and co-inventor of the breast cancer vaccine technology. The SABCS poster presentation is available at . "Triple-negative breast cancer remains one of the most challenging subtypes to address, and Phase 1 trials are an important step in determining whether a new approach can be administered safely and activate the immune system as intended," said G. Thomas Budd, M.D., of Cleveland Clinic's Cancer Institute and principal investigator of the study. "In this trial, the investigational α-lactalbumin vaccine was safe and well tolerated at the maximum tolerated dose and generated protocol-defined immune responses in 74% of participants—results that support continued clinical evaluation." Topline Phase 1 results: All major primary endpoints were met 74% of participants demonstrated protocol-defined immune responses; α-lactalbumin (aLA)-specific T cell responses were observed per protocol-defined criteria Vaccine was safe and well tolerated at the MTD, with adverse events primarily injection-site irritation Preliminary Immunohistochemistry (IHC) of primary tumors showed aLA expression ranging from absent to strong; analyses correlating expression to immune response and clinical outcomes are ongoing Participants will be followed for five years after completing the study Combination of Keytruda and the vaccine also generated antigen-specific T cell responses and showed no major additional side effects Data will inform planned Phase 2 study design, including a potential Phase 2 combination study with Keytruda in the neoadjuvant setting among newly diagnosed breast cancer patients The Phase 1 study evaluated safety and monitored immune response to an investigational vaccine targeting α-lactalbumin (aLA). The trial enrolled 35 participants across three cohorts: Cohort Ia (n=26), women who completed standard-of-care treatment, including surgery, for early-stage TNBC within three years and were tumor-free but at elevated risk of recurrence; Cohort Ib (n=4), cancer-free women with BRCA1, BRCA2, or PALB2 mutations who elected preventive mastectomy and were vaccinated prior to surgery; and Cohort Ic (n=5), women with TNBC receiving pembrolizumab (Keytruda) in the adjuvant (post-surgery) setting, with evaluation of safety of combination administration and immune responses. In Cohort Ia, at the MTD, the vaccine was reported as safe, with no flu-like symptoms (fever and myalgias), no abnormal clinical laboratory tests, and no other observed adverse side effects in this cohort; the primary notable adverse event was injection-site irritation. Participants demonstrated aLA-specific T cell responses, including production of interferon gamma and interleukin-17. In Cohort Ib, safety and tolerability were similar to Cohort Ia. Immunohistochemistry analyses of resected breast tissue are ongoing and will be presented in a future scientific presentation. In Cohort Ic, a key objective was to assess whether administration of the investigational vaccine in combination with pembrolizumab could create intolerable side effects. No major adverse side effects were reported; as in other cohorts, the primary adverse event was injection-site irritation. Two participants experienced Grade 3 adverse events consisting of greater irritation at an injection site. The investigational vaccine targets α-lactalbumin, a lactation protein generally expressed in the breast during lactation but not at other times in life or in other normal tissues. In many breast cancers, malignant cells express α-lactalbumin. The vaccine is designed to activate the immune system to direct cytotoxic T cells toward tumor cells expressing α-lactalbumin, with the goal of providing preemptive immune protection against emerging tumors that express this antigen. The vaccine is based on preclinical research led by the late Vincent Tuohy, Ph.D., who served as the Mort and Iris November Distinguished Chair in Innovative Breast Cancer Research at Cleveland Clinic. "It was Dr. Tuohy's hope that this vaccine would demonstrate the potential of immunization as a new way to combat breast cancer, and that a similar approach could someday be applied to other types of malignancies," said Dr. Johnson. "Our findings that the majority of participants across all three cohorts demonstrated an immune response to α-lactalbumin is an encouraging sign." Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences, stated, "We are very encouraged that the final Phase 1 data met all major primary endpoints, with the vaccine demonstrating a favorable tolerability profile at the MTD and protocol-defined immune responses in the majority of participants. We appreciate the support provided through the U.S. Department of Defense grant that enabled this study in collaboration with Cleveland Clinic, and we look forward to engaging with regulators and advancing plans for a Phase 2 study."

Anixa's therapeutic portfolio consists of an ovarian cancer immunotherapy program being developed in collaboration with Moffitt Cancer Center, which uses a novel type of CAR-T, known as chimeric endocrine receptor-T cell (CER-T) technology. This technology is differentiated from other cell therapies as the natural ligand of the FSHR receptor, FSH, binds to the FSHR receptor on the tumor cell instead of an antibody fragment. Moffitt is a world leader in cancer immunotherapy treatments, pioneering next-generation cell therapies such as CAR-T, and tumor infiltrating lymphocytes (TILs) to harness the power of the immune system. The Company's vaccine portfolio includes vaccines being developed in collaboration with Cleveland Clinic to treat and prevent breast cancer and ovarian cancer, as well as additional cancer vaccines to address many intractable cancers, including high incidence malignancies in lung, colon, and prostate. These vaccine technologies focus on immunizing against "retired" proteins that have been found to be expressed in certain forms of cancer.

Patent Extends Protection for Novel Vaccine Targeting a Cancer Projected to Strike Nearly 300,000 U.S. Women in 2026 SAN JOSE, Calif., Nov. 12, 2025 /PRNewswire/ -- Anixa Biosciences, Inc. ("Anixa" or the "Company") (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer, today announced that the United States Patent and Trademark Office (USPTO) will issue U.S. Patent Number 12,472,205 on November 18, 2025, covering key aspects of the Company's breast cancer vaccine technology. The patent protects novel methods of inducing an immune response to α-lactalbumin protein—a protein typically found only in normal breast tissue during lactation but also expressed in certain breast cancers, making it an attractive target for immunoprevention strategies. The co-inventors of the patent are the late Dr. Vincent Tuohy, and Dr. Justin Johnson of Cleveland Clinic. "Our breast cancer vaccine program is a cornerstone of our strategy to develop next-generation preventive immunotherapies," stated Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences. "This new patent meaningfully extends the duration of our intellectual property protection and reinforces our commitment to addressing a disease that affects hundreds of thousands of women each year. With a strong and growing global patent portfolio, we are well-positioned to advance a vaccine that could fundamentally change how we prevent breast cancer in healthy women." Anixa's breast cancer vaccine, developed in collaboration with Cleveland Clinic, represents a novel approach to the prevention and treatment of breast cancer. The vaccine was invented at Cleveland Clinic, and this patent—along with others related to this technology—has been exclusively licensed to Anixa Biosciences. This patent issuance builds upon the Company's broad and expanding intellectual property portfolio, strengthening foundational patent protection for the breast cancer vaccine program into the mid-2040s. Despite significant progress in breast cancer treatment, the disease remains the most commonly diagnosed cancer among women worldwide. In the United States alone, over 297,000 new cases of invasive breast cancer are projected in 2025, with approximately 43,000 women expected to die from the disease. No FDA-approved vaccine currently exists to prevent breast cancer, representing a major and unmet need in the field of preventive oncology. Anixa's investigational vaccine aims to stimulate the immune system to recognize and eliminate pre-malignant and malignant cells expressing α-lactalbumin—while sparing normal tissue. By targeting this "retired" protein, which is generally absent from healthy tissue except during lactation, the vaccine has the potential to minimize off-target effects and provide long-lasting immune protection.
