US-based Anixa Biosciences, Inc. has announced that the Japanese Patent Office has issued a Decision to Grant of a patent to Cleveland Clinic titled, "Ovarian Cancer Vaccines." The technology was invented by Drs. Vincent K. TuohySuparna Mazumder and Justin M. Johnson at Cleveland Clinic. Anixa is the worldwide licensee for the vaccine technology. Patents for the technology were issued in the U.S. and Europe in 2021.

The ovarian cancer vaccine targets the extracellular domain of anti-Müllerian hormone receptor 2 (AMHR2-ED), which is expressed in the ovaries but disappears as a woman reaches and advances through menopause. Of note, the majority of ovarian cancer diagnoses occur after menopause, and AMHR2-ED is expressed again in the majority of ovarian cancers. By receiving a vaccine such as Anixa's that targets AMHR2-ED after reaching menopause, ovarian cancer, historically one of the most aggressive gynecological cancers, could be prevented from ever developing.

Preclinical work to advance the vaccine is ongoing through the PREVENT Program at the National Cancer Institute (NCI), which supports preclinical innovative interventions and biomarkers for cancer prevention and interception. Preclinical data published in Cancer Prevention Research in 2017 supports ongoing advancement toward clinical studies.
