Anixa Biosciences Initiates Dosing in Third Cohort in its Ovarian Cancer CAR-T Clinical Trial

Third cohort dose is one million CAR positive cells; ten times higher than the first cohort dose

SAN JOSE, Calif., Nov. 18, 2024 /PRNewswire/ -- Anixa Biosciences, Inc. ("Anixa" or the "Company") (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer, today announced that it has dosed its first patient in the third cohort in the ongoing Phase 1 clinical trial of its novel chimeric antigen receptor-T cell (CAR-T) therapy for recurrent ovarian cancer. The study is being conducted through a research partnership with Moffitt Cancer Center ("Moffitt").

No dose limiting toxicity was observed in the initial three-patient cohort or in the second three-patient cohort, in which patients received a CAR-T cell dose triple that of the first cohort. After the required one-month waiting period to assess the occurrence of dose limiting toxicity and review of all safety data, the trial has now dosed its first patient in the third cohort at a tenfold increase over the initial dose.

Anixa's FSHR-mediated CAR-T technology targets the follicle-stimulating hormone receptor (FSHR), which research indicates is exclusively expressed on ovarian cells, tumor vasculature, and certain cancer cells. The first-in-human trial (NCT05316129) is enrolling adult women with recurrent ovarian cancer who have progressed on at least two prior therapies. The study is designed to evaluate safety and identify the maximum tolerated dose, while monitoring efficacy.

Dr. Robert Wenham, principal investigator of the study and Chair of the Department of Gynecologic Oncology at Moffitt, stated, "With no dose-limiting safety issues observed in the first and second patient cohorts, we have advanced to the next cohort to evaluate a 10x higher dose compared with the starting dose. As the trial continues, our aim is to demonstrate the tolerability of our CAR-T but we are optimistic and hopeful about seeing efficacy in this solid tumor—a challenging area for traditional CAR-T therapies, which have shown efficacy mainly in hematologic tumors and lymphomas. We are very encouraged how the trial has progressed and our observation in one patient from the first cohort who had relative stability and even some mild improvement for well over a year after her infusion. This is highly unusual for a platinum resistant multiply treated ovarian cancer. A tumor biopsy showed necrosis and T cell infiltration. Based on these findings, we recently submitted an amendment to the trial protocol to allow patients who may benefit from an additional dose. Generally, we expect higher cell doses to increase efficacy, although we also anticipate a second dose may further improve response rates and durability. We are proud of the progress to date and look forward to treating additional patients in the third cohort."

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 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. 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.
