Recent Company History

Over recent months, Anixa has repeatedly highlighted progress in its oncology pipeline. Updates on conference presentations and media appearances in April 2026 for its ovarian cancer CAR-T program and α-lactalbumin breast cancer vaccine were followed by positive moves of 0.37% to 3.86%, while the Apr 1 Phase 1 breast cancer vaccine milestone saw a 5.43% gain. Today’s Mexican patent issuance extends this trajectory of clinical and program-building news supporting the vaccine’s advancement.

Key Terms

triple-negative breast cancer, α-lactalbumin, Phase 1, maximum tolerated dose, +1 more

5 terms

triple-negative breast cancer medical

"greater late-stage breast cancerdiagnoses and higher triple-negative breast cancer incidence rates"

Triple-negative breast cancer is a type of breast cancer that lacks three common markers used to identify and treat the disease effectively. Because it doesn’t respond to some targeted therapies, it can be more difficult to treat and may have a more aggressive progression. This impacts the development of new treatments and can influence the outlook for healthcare companies involved in cancer research and pharmaceuticals.

α-lactalbumin medical

"vaccine is based on immunizing against human α-lactalbumin, a protein associated with lactation"

α-lactalbumin is a naturally occurring protein found in mammalian milk that supplies essential building blocks and supports nutrient absorption; think of it as a concentrated, high-quality protein ingredient used to boost the nutritional value of infant formula, medical nutrition and some supplements. Investors care because its use, purity, and supply affect product claims, regulatory approvals, patent positions and consumer demand in nutrition and health markets—factors that influence revenue and margins.

Phase 1 medical

"Positive Phase 1 results showed that the vaccine met all primary endpoints"

Phase 1 is the first stage of testing a new drug or medical treatment in people, focused primarily on safety, how the body handles the product, and finding a tolerated dose. Think of it as a short, tightly controlled experiment with a small group to check for dangerous side effects before wider testing; for investors it is an early milestone that reduces some uncertainty but still carries high risk and potential for both big value changes and setbacks.

maximum tolerated dose medical

"was safe and well tolerated at the maximum tolerated dose, and elicited"

Maximum tolerated dose is the highest amount of a substance, such as a medication or chemical, that can be used without causing unacceptable side effects or harm. It’s like finding the maximum speed you can drive without risking a ticket or accident. For investors, understanding this concept helps gauge how much risk or exposure is safe or sustainable in a given situation.

Phase 2 clinical trial medical

"Based on these findings, Anixa is moving forward with preparations for a Phase 2 clinical trial."

A phase 2 clinical trial is a research study that tests a new medical treatment or drug to see if it is effective and safe for a specific condition. It involves a larger group of people than earlier trials and helps determine whether the treatment should move forward to more extensive testing. For investors, successful phase 2 results can signal potential for future approval and commercial success, while setbacks may indicate challenges ahead.

Expands global intellectual property coverage in markets with greater late-stage breast cancer
diagnoses and higher triple-negative breast cancer incidence rates

New patent will provide IP protection of Breast Cancer Vaccine in Mexico into 2040

SAN JOSE, Calif., April 29, 2026 /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 Mexican Institute of Industrial Property (IMPI) has issued Patent Number 432748, covering key aspects of the Company's breast cancer vaccine technology.

"This newly issued patent continues the broad international recognition of the novelty and potential of our breast cancer vaccine," stated Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences. "As we continue clinical development in the U.S., our growing international patent estate further strengthens our ability to pursue global opportunities and potentially partner with larger pharmaceutical companies for worldwide commercialization."

Anixa's breast cancer vaccine, developed in collaboration with Cleveland Clinic, represents a novel approach to the prevention and treatment of breast cancer. Anixa's vaccine is based on immunizing against human α-lactalbumin, a protein associated with lactation that is aberrantly expressed in certain types of breast cancer. This "retired" protein vaccine strategy aims to selectively prime the immune system to prevent tumor formation while avoiding harm to normal tissue. The vaccine was invented at Cleveland Clinic, and this patent—along with others related to this technology—has been exclusively licensed to Anixa Biosciences. Positive Phase 1 results showed that the vaccine met all primary endpoints, was safe and well tolerated at the maximum tolerated dose, and elicited protocol-defined immune responses in 74% of participants across all doses tested. Based on these findings, Anixa is moving forward with preparations for a Phase 2 clinical trial.

This patent issuance builds upon the Company's broad and expanding intellectual property portfolio, extending foundational patent protection for the breast cancer vaccine program into the 2040s in multiple jurisdictions throughout the world. By reinforcing its global patent estate, Anixa is laying the groundwork for future international development and commercialization strategies.

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 liraltagene autoleucel, or lira-cel, an ovarian cancer immunotherapy 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. The breast and ovarian cancer vaccines were developed at Cleveland Clinic and exclusively licensed to Anixa. Cleveland Clinic is entitled to royalties and other commercialization revenues from the Company related to these vaccine technologies. Anixa's unique business model of partnering with world-renowned research institutions on all stages of development allows the Company to continually examine emerging technologies in complementary fields for further development and commercialization.
