Cherry biolabs was founded in 2019 as a Spin-off from the University Hospital of Würzburg with a focus on biotechnology and immunotherapy target validation.


The essence of the technology is a T-cell engaging molecule that is split into two complementary fragments coined Hemibodies. Individual Hemibodies are inert but reconstitute T-cell engaging functions, in vivo, after binding to an antigen combination uniquely expressed on cancer cells. Hemibodies address cancer types that are not druggable by competing immunotherapy strategies, including bi-specific antibodies and CAR-T-cell formats, and avoid toxic side effects.  


Prof. Gernot Stuhler, MD


Gernot is the inventor of the hemibody technology and Managing Director.

Gernot is a hematologist/oncologist with a strong background in allogeneic stem cell transplantation.

He was trained in Immunology at the Max-Planck-Institute for Biology/Immunogenetics in Tübingen/Germany and at the Dana Farber Cancer Institute/Harvard Medical School in Boston/USA. During his time at Würzburg University, where bispecific T cell engagers were clinically developed, he got involved in antibody engineering. Currently, he is heading a group of scientists aiming to improve T cell engaging antibody derivatives and to implement combinatorial immunotargeting strategies.
