For our drug discovery projects in preclinical development, we collaborate with Sjeng Horbach for conducting activities in preclinical toxicology and drug safety.
Next to expert contributions in this field, Sjeng plays an important role in the multidisciplinary project team dynamics, interpreting project data and aligning the various inter-disciplinary activities in one operational plan. His contributions have certainly enabled progression of our most advanced wholly-owned project through pre-clinical development.

Sjeng Horbach brings enormous experience in toxicology, building on an outstanding track record in supporting all stages of drug development for small and large molecules. I have had the pleasure of working with Sjeng on a large and diverse set of therapeutic antibodies ranging from canonical antibodies to antibody-drug conjugates and bispecific antibodies, with a recent emphasis on immune-oncology compounds including T-cell engagers. Sjeng is not only very knowledgeable and collaborative, but also very pleasant to work with. I recommend him most highly.
