The SILENCE project - less toxicity and better efficacy: imaging to optimise antibody-based therapies
Antibody‑based therapies are an important and rapidly growing group of drugs. These treatments are designed to recognise specific markers on cells and deliver their effect precisely where it is needed. However, many promising antibody‑based therapies still cause unwanted side effects because they can also accumulate in healthy organs and engage immune mechanisms outside the tumor.
In the SILENCE project, the University Medical Center Groningen (UMCG Dept. of Clinical Pharmacy and Pharmacology, Prof. M.N. Lub de Hooge’s team) and the biopharmaceutical company Zymeworks are joining forces to better understand and improve the safety of these treatments. Together, they will investigate how engineered antibodies, modified in the part that interacts with the immune-interacting Fc region, move through the body and how their design could reduce unwanted effects.
SILENCE will use advanced optical and nuclear imaging to track novel Fc‑modified antibodies travel in the body, compared with unmodified ones. Antibodies will be labelled with radioactive tracers or fluorescent dyes, so that their journey in mice can be followed from whole‑body level down to individual cells. The results of these studies will be used to build refined models that predicts how these Fc-engineered antibodies may behave in humans.
The outcomes of the SILENCE project will accelerate the development of next‑generation treatments with fewer side effects, potentially also beyond oncology.
