Yes, the title may have surprised you, but it’s true. Vaximm is one of the few biotechs worldwide using bacteria to activate the immune system against cancer. I was really surprised about how elegant the technology is when I had a chat with the Executive Chairman Klaus Breiner at BioEquity in Copenhagen.
Vaximm is based in Basel (Switzerland) and Mannheim (Germany) and was founded in late 2008. The entire platform of the company is based on using an engineered version of commonly-used vaccination bacteria (Ty21a) to present cancer-fighting antigens.
How does it really work? Here’s a diagram from the company:
The engineered bacteria are given orally to the patients. They go to the small intestine’s lymph nodes to infect mostly macrophages, which will then express the specific antigen and after self-destruction are processed by the immune system activating T-cells against that antigen. “Our first-in-class approach is really unique” commented Breiner.
“Developing such a platform and novel mechanism of action is definitely not cheap”,
