SAN JOSE, Calif., Aug. 7, 2023. Anixa Biosciences, Inc. (“Anixa” or the “Firm”), a biotechnology firm targeted on the remedy and prevention of most cancers, in the present day introduced that its accomplice, Cleveland Clinic, has begun enrolling topics in a remedy arm evaluating the mix of the Firm’s breast most cancers vaccine with Keytruda® (pembrolizumab). An enlargement of the continuing Section 1 dose escalation trial of Anixa’s breast most cancers vaccine, this remedy arm goals to find out if the vaccine/Keytruda mixture will increase immune response.

Anixa’s breast most cancers vaccine is designed to generate T cells that focus on triple damaging breast most cancers (“TNBC”). Keytruda, a remedy marketed by Merck (NYSE: MRK), is authorised to be used with chemotherapy earlier than surgical procedure after which alone after surgical procedure to deal with each high-risk early-stage and superior TNBC.

Keytruda is a sort of immunotherapy generally known as a checkpoint inhibitor. T cells, a sort of white blood cell concerned within the physique’s immune system, have receptor proteins on their floor referred to as checkpoints. These checkpoints are utilized by different immune cells to modulate the exercise of T cells. Most cancers cells, reminiscent of TNBC cells, have developed mechanisms to focus on checkpoints to inhibit the exercise of T cells, in addition to different immune cells. This inhibition allows the most cancers cells to flee destruction by cytotoxic T cells. One among these key checkpoint receptors is called PD-1 (Programmed Cell Loss of life Protein-1). TNBC, like many different cancers, expresses a protein that binds to the PD-1 protein on T cells and basically turns them “off.” Keytruda is a monoclonal antibody, which blocks the flexibility of the most cancers cells to inactivate T cells by shielding the PD-1 receptor.Dr. Amit Kumar, Chairman and CEO of Anixa said, “Cleveland Clinic has demonstrated in each preclinical and scientific research that our breast most cancers vaccine induces an immune response–together with, we imagine, manufacturing of T cells that may goal TNBC–so we imagine that the addition of Keytruda may have a synergistic impact. If a vaccine induces the creation of T cells focusing on TNBC, and Keytruda typically maintains T cell exercise, the mix might be very potent. We’re grateful to the U.S. Division of Protection for offering the funding for this new arm of the trial and look ahead to Cleveland Clinic’s presentation of the up to date information from this trial on the San Antonio Breast Most cancers Symposium (SABCS) in December.”

About Anixa’s Breast Most cancers Vaccine Medical Trial
The Section 1a research is designed to judge the protection of the vaccine, establish the Most Tolerated Dose (MTD), and monitor the immune response in vaccinated girls. All individuals within the Section 1a research are girls who’ve had triple damaging breast most cancers (TNBC) throughout the final three years and have been curatively handled having undergone normal of care. On the time of vaccination, these individuals are tumor-free, as decided by normal diagnostic methods, however are at excessive danger of recurrence.

About Triple-Adverse Breast Most cancers
One in eight girls within the U.S. will likely be identified with an invasive breast most cancers sooner or later of their lives. Roughly 10-15% of these diagnoses are TNBC, nonetheless TNBC accounts for a disproportionately increased proportion of breast most cancers deaths and has a better price of recurrence. This type of breast most cancers is twice as prone to happen in African-American girls, and roughly 70% to 80% of the breast tumors that happen in girls with mutations within the BRCA1 genes are triple-negative breast most cancers.

About Anixa Bioscience’s Breast Most cancers Vaccine
Anixa’s breast most cancers vaccine takes benefit of endogenously produced proteins which have a operate at sure instances in life, however then grow to be “retired” and disappear from the physique. One such protein is a breast-specific lactation protein, α-lactalbumin, which is now not discovered post-lactation in regular, ageing tissues, however is current within the majority of triple-negative breast cancers. Activating the immune system towards this “retired” protein gives preemptive immune safety towards rising breast tumors that specific α-lactalbumin. The vaccine additionally comprises an adjuvant that prompts an innate immune response, which permits the immune system to mount a response towards rising tumors to forestall them from rising. This vaccine know-how was invented by the late Dr. Vincent Tuohy, who was the Mort and Iris November Distinguished Chair in Progressive Breast Most cancers Analysis within the Division of Irritation and Immunity at Cleveland Clinic’s Lerner Analysis Institute, and Cleveland Clinic solely licensed the know-how to Anixa Biosciences. Dr. Tuohy was entitled to a portion of the commercialization revenues acquired by Cleveland Clinic and in addition held fairness in Anixa. The know-how is at present being examined in a Section 1 scientific trial, performed at Cleveland Clinic and funded by a grant from the U.S. Division of Protection to Cleveland Clinic.

About Anixa Biosciences, Inc.
Anixa is a clinical-stage biotechnology firm targeted on the remedy and prevention of most cancers. Anixa’s therapeutic portfolio consists of an ovarian most cancers immunotherapy program that makes use of a novel kind of CAR-T generally known as chimeric endocrine receptor T-cell (CER-T) know-how, and is being developed in collaboration with Moffitt Most cancers Heart. The Firm’s vaccine portfolio features a novel vaccine being developed in collaboration with Cleveland Clinic to forestall breast most cancers – particularly triple damaging breast most cancers (TNBC), probably the most deadly type of the illness – in addition to a vaccine to forestall ovarian most cancers. These vaccine applied sciences give attention to immunizing towards “retired” proteins which were discovered to be expressed in sure types of most cancers. Anixa’s distinctive enterprise mannequin of partnering with world-renowned analysis establishments on scientific growth permits the Firm to repeatedly study rising applied sciences in complementary fields for additional growth and commercialization.
