Immune Cell Mediator Platform
Ymmunobio is developing a proprietary class of CEACAM1* immune agonistic antibodies. These antibodies have a direct co-stimulatory effect on immune cells in addition to interfering with the CEACAM1-CEACAM mediated check-point blockade. We are utilizing our proprietary platform to employ the immune system to fight cancer.

Our Team
We have assembled a world-class team, including one of the most renowned scientific leaders in the field of CEACAM research, Dr. Bernhard B. Singer, and the seasoned drug development expert Dr. Katrin Rupalla. Our distinguished scientific and clinical oncology advisors include Prof. Dr. Iris Helfrich, Dr. Bruno Osterwalder and Prof. Dr. Keith Skubitz.

Our Science
Our goal is to increase the efficiency of the adaptive and innate immune system to fight cancer. We are targeting defined CEACAM1 receptor isoforms playing a major role in the immune response and cancer cell evolution.
Our science is based on the leading research of Dr. B.B. Singer over the last 25 years with regard to the role of CEACAM1 in the immune system.

Our Pipeline
Our pipeline consists of several generations of immune agonistic antibodies targeting CEACAM1.
Two proprietary antibodies of our platform currently in preclinical development are:
2nd Generation
YB-200 is a first-in-class anti-human CEACAM1/5 immune agonistic antibody that has shown in multiple preclinical models a direct co-stimulatory effect on immune cells in addition to interfering with the CEACAM1-CEACAM mediated check-point blockade.


3rd Generation
The third generation anti-human CEACAM1antibody, YB-300, is enhancing the co-stimulatory effect in combination with YB-200.
4th Generation
The fourth generation is currently under development
