Anixa Biosciences and Cleveland Clinic Present Positive Data for Phase 1 Study of Breast Cancer Vaccine
Immune responses were observed at all dose levels
SAN JOSE, Calif., April 17, 2023 /PRNewswire/ -- Anixa Biosciences, Inc. (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer today announced that Cleveland Clinic presented the most up-to-date data from the Phase 1 Trial of its breast cancer vaccine. The data presented showed that in the vaccinated women who have been tested to date, various levels of antigen-specific T cell responses were observed at all dose levels. The presentation was made by G. Thomas Budd, M.D., of Cleveland Clinic's Taussig Cancer Institute and principal investigator of the study. This breast cancer vaccine technology was invented at Cleveland Clinic, where the trial is being conducted, and Anixa is the exclusive worldwide licensee. The trial is funded by a grant from the U.S. Department of Defense to Cleveland Clinic.
The Phase 1a study is designed to evaluate the safety of the vaccine, identify the Maximum Tolerated Dose (MTD), and monitor the immune response in vaccinated women. All participants in the Phase 1a study are women who have had triple negative breast cancer (TNBC) within the last three years and have been curatively treated having undergone standard of care. At the time of vaccination, these participants are tumor-free, as determined by standard diagnostic techniques, but are at high risk of recurrence.
"We are testing this vaccine to determine if a vaccinated patient's immune system is trained to destroy cancer cells expressing α-lactalbumin, a protein found on TNBC cancer cells and not on normal cells. To evaluate the vaccination effect, immune mediated biomarkers of T cell activation and antibody production specific against α-lactalbumin are measured. We are heartened by the data, and look forward to additional studies," stated Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences.
"We are pleased that varying degrees of antigen-specific T cell responses were observed at all dose levels tested to date, however, the Phase 1 trial is not designed to determine whether the responses are sufficient to prevent recurrence or primary tumorogenesis, said Dr. Budd. "We expect successive studies to determine how effective the immune responses are in preventing cancer."
About Triple-Negative Breast Cancer
One in eight women in the U.S. will be diagnosed with an invasive breast cancer at some point in their lives. Approximately 10-15% of those diagnoses are TNBC, however TNBC accounts for a disproportionately higher percentage of breast cancer deaths and has a higher rate of recurrence. This form of breast cancer is twice as likely to occur in African-American women, and approximately 70% to 80% of the breast tumors that occur in women with mutations in the BRCA1 genes are triple-negative breast cancer.
About Anixa Bioscience's Breast Cancer Vaccine
Anixa's breast cancer vaccine takes advantage of endogenously produced proteins that have a function at certain times in life, but then become "retired" and disappear from the body. One such protein is a breast-specific lactation protein, α-lactalbumin, which is no longer found post-lactation in normal, aging tissues, but is present in the majority of triple-negative breast cancers. Activating the immune system against this "retired" protein provides preemptive immune protection against emerging breast tumors that express α-lactalbumin. The vaccine also contains an adjuvant that activates an innate immune response, which allows the immune system to mount a response against emerging tumors to prevent them from growing. This vaccine technology was invented by the late Dr. Vincent Tuohy, who was the Mort and Iris November Distinguished Chair in Innovative Breast Cancer Research in the Department of Inflammation and Immunity at Cleveland Clinic's Lerner Research Institute. Dr. Tuohy was inventor of the technology, which Cleveland Clinic exclusively licensed to Anixa Biosciences. He was entitled to a portion of the commercialization revenues received by Cleveland Clinic and also held equity in Anixa.
About Anixa Biosciences, Inc.
Anixa is a clinical-stage biotechnology company focused on the treatment and prevention of cancer. 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. The company's vaccine portfolio includes a novel vaccine being developed in collaboration with Cleveland Clinic to prevent breast cancer – specifically triple negative breast cancer (TNBC), the most lethal form of the disease – as well as a vaccine to prevent ovarian cancer. These vaccine technologies focus on immunizing against "retired" proteins that have been found to be expressed in certain forms of cancer. Anixa's unique business model of partnering with world-renowned research institutions on clinical development allows the company to continually examine emerging technologies in complementary fields for further development and commercialization.
