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.
J&S Preclinial Solutions combines decades of preclinical safety assessment and cutting-edge in vivo efficacy experience in immunology/oncology with a getting-things done mentality and taking responsibility, accountability and on top of that great personalities. This mix is pushing any project at hand forward in a great Team spirit.
