KEY-Vaxx is a B-cell peptide cancer vaccine which aims to induce the body to produce polyclonal antibodies that block PD-1 signalling, and potentially produce an anticancer effect similar to Keytruda, Opdivo and the other immune checkpoint inhibitor monoclonal antibodies that are transforming the treatment of a range of cancers.
KEY-Vaxx has shown potential in preclinical studies, outperforming an industry-standard antibody in a mouse model of HER2+ colorectal cancer.
New provisional patent
The protection of Imugene’s global position in PD-1 B-cell cancer vaccines has been strengthened with the filing of a new provisional patent in Australia titled “A vaccine composition and uses thereof”.

“We are extremely pleased with the progress made from our expert scientific team.”
