  21. Beyond Antibodies Chapter 4 Antibody Structure can be modified to make dramatically different Therapeutics Multispecific Antibody formats Types and Features BITE technology [Micromet] Antibody-ligand fusion proteins [Apoptosis inducing] Terminology

  22. Diverse variety of multi-specific antibody formats available Amino acids in the interface of CH3 domains, which form homodimersnaturally, are mutated at sites where two chains interact, such that one of them has a small side chain (hole), while the other has a large side chain (knob). The more favorable protein interaction between knobs and holes led to the almost exclusive heterodimerization of two different CH3 domains Two scFvs genetically fused to a human Immunoglobulin G (IgG), stability engineered, prokaryotic expression system and favourable biophysical properties Dual variable domain-Ig, multispecific, two antigen combining sites with different specificity in tandem on an IgG Germaine Fuh, Genentech, IBC Antibody Engineering 2009

  23. BiTE Technology Platform BiTE ;MT103 [Rabbit anti-CD19 scFv fragment x scFv fragment of a murine anti-CD3 mAb] rM28; [Murine anti-M-AP scFv fragment x scFV fragment of a murine anti-CD28 mAb] Patrick A. Baeuerle, Micromet, Inc. San Diego, December , 2009

  24. BiTE Technology – Mechanism of Action Blinatumomab (MT103; Micromet/Medimmune), a BiTE specific for CD19 and CD3 Patrick A. Baeuerle, Micromet, Inc. San Diego, December , 2009
