 Anixa Biosciences, Inc. (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer  announced that Cleveland Clinic presented the most up-to-date data from the Phase 1 Trial of its breast cancer vaccine.  The data presented showed that in the vaccinated women who have been tested to date, various levels of antigen-specific T cell responses were observed at all dose levels.  The presentation was made by G. Thomas Budd, M.D., of Cleveland Clinic's Taussig Cancer Institute and principal investigator of the study.  This breast cancer vaccine technology was invented at Cleveland Clinic, where the trial is being conducted, and Anixa is the exclusive worldwide licensee.  The trial is funded by a grant from the U.S. Department of Defense to Cleveland Clinic.

The Phase 1a study is designed to evaluate the safety of the vaccine, identify the Maximum Tolerated Dose (MTD), and monitor the immune response in vaccinated women.  All participants in the Phase 1a study are women who have had triple negative breast cancer (TNBC) within the last three years and have been curatively treated having undergone standard of care.  At the time of vaccination, these participants are tumor-free, as determined by standard diagnostic techniques, but are at high risk of recurrence.

"We are testing this vaccine to determine if a vaccinated patient's immune system is trained to destroy cancer cells expressing α-lactalbumin, a protein found on TNBC cancer cells and not on normal cells.  To evaluate the vaccination effect, immune mediated biomarkers of T cell activation and antibody production specific against α-lactalbumin are measured.  We are heartened by the data, and look forward to additional studies," stated Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences.

"We are pleased that varying degrees of antigen-specific T cell responses were observed at all dose levels tested to date, however, the Phase 1 trial is not designed to determine whether the responses are sufficient to prevent recurrence or primary tumorogenesis, said Dr. Budd.  "We expect successive studies to determine how effective the immune responses are in preventing cancer."
