Immunwork's guiding concept in designing novel drugs is to furnish the drug molecules both targeting and effetor functions. This concept is applied not only in designing drugs for oncological applications, but also drugs for other diseases.

The core of our technology is built upon "multi-arm linkers", which are synthesized using amino acids, including PEGylated amino acids, and bear multiple linking arms. Multiple targeting or effector elements can be conjugated to the linking arms, forming bundles of fatty acids, cytotoxic drugs, chelators, etc., which can augment targeting or effector functions. These bundles serve either a targeting or an effector moiety in paring respectively with an effector or targeting moiety.
