The vaccine is designed to stimulate the immune system to recognize and target breast cancer before it can recur or develop. A total of 35 women received the vaccine in the study, spanning three distinct patient cohorts:

TNBC Group: Women who have completed treatment for triple-negative breast cancer, are currently cancer-free, and are at risk of recurrence.
Prevention Group: Women who are cancer-free but carry genetic mutations associated with elevated breast cancer risk, and who elected to undergo preventive mastectomy.
Pembrolizumab (Keytruda ) Group: Women receiving pembrolizumab in a post-operative setting who were administered the vaccine concurrently with the checkpoint inhibitor.
The trial enrolled 26 patients in the TNBC group, four in the Prevention group, and five in the Pembrolizumab group.

With the completion of all patient visits and sample collection, comprehensive data analysis can now proceed. Following analysis, a final study report will be submitted to the Department of Defense, and a Clinical Study Report (CSR) will be filed with the U.S. Food and Drug Administration (FDA).

Cleveland Clinic will present full clinical results at the San Antonio Breast Cancer Symposium on December 11, 2025.

Dr. G. Thomas Budd, of Cleveland Clinic Cancer Institute and Prinicipal Investigator of the study, commented, "We are pleased by the data we are seeing from this trial. Preliminary results indicate that our breast cancer vaccine is well tolerated, with more than 70% of participants demonstrating protocol-defined immune responses. We look forward to presenting the final trial data at the San Antonio Breast Cancer Symposium later this year."

Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences, commented, "While cancer vaccines have historically faced considerable challenges, our approach targets a novel antigen that has not been explored in this setting. We believe this strategy could represent a new paradigm in immuno-oncology, with potential utility in both the prevention and treatment of breast cancer."
