Anixa Biosciences Announces Maximum Tolerated Dose Reached in Trial of Preventative Breast Cancer Vaccine


DECEMBER 08, 2022

SAN JOSE, Calif., Dec. 8, 2022 /PRNewswire/ -- Anixa Biosciences, Inc. (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer and infectious diseases, today announced the maximum tolerated dose (MTD) has been reached in the Phase 1a trial of its preventative breast cancer vaccine.   

The trial is an open-label, multiple-ascending dose Phase 1a trial to evaluate safety and monitor immune response after vaccination.  A critical goal was to determine the maximum tolerated dose of the vaccine.  The MTD is the highest dose of a medicine or treatment that will produce the desired effect without resulting in unacceptable side effects.  Higher concentrations may be effective but may induce side effects that deter use or outweigh the benefits of treatment. 


The MTD will guide dosing in successive Phase 2 and Phase 3 trials.  Recently, a Phase 1b trial was commenced, based on the results to date of the Phase 1a trial.  The Phase 1a and Phase 1b trials are currently being conducted at Cleveland Clinic and include women who have previously been diagnosed with triple negative breast cancer and are currently cancer free and at risk of recurrence, and healthy cancer free women at high risk for developing breast cancer in the future, respectively.  Future trials are expected to be conducted at multiple sites. 

"We are pleased to have reached this important milestone in the clinical.

development of our preventative breast cancer vaccine, and we look forward to completing enrollment for the Phase 1a trial," stated Dr. Amit Kumar, Chairman and CEO of Anixa.  "After the last participant is vaccinated and completes all follow up tests, we will compile and analyze the data.  We look forward to presenting the complete immunological data from the trial at a scientific conference or similar setting in the second quarter of 2023."

About Anixa Bioscience's Breast Cancer Vaccine

Anixa's breast cancer vaccine, currently in Phase 1 trials, 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 Dr. Vincent Tuohy, 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 is named as inventor on the technology, which Cleveland Clinic exclusively licensed to Anixa Biosciences.  Dr. Tuohy will receive a portion of commercialization revenues received by Cleveland Clinic for this technology and also holds personal equity in Anixa.

About Anixa Biosciences, Inc.

Anixa is a clinical-stage biotechnology company with programs addressing cancer and infectious disease.  Anixa's portfolio of therapeutics includes a 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, and, with partner MolGenie GmbH, a COVID-19 program focused on compounds targeting the Mpro enzyme of SARS-CoV-2, which is largely conserved across all recently identified variants.  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.  To learn more, visit or follow Anixa on TwitterLinkedInFacebook and YouTube.
