Blocking the TSH receptor with human monoclonal autoantibody K1-70TM in patients with graves’ disease – results from a phase 1 clinical trial

Furmaniak Jadwiga , Sanders Jane , Sanders Paul , Li Yang , Rees Smith Bernard

Objectives: TSH receptor (TSHR) autoantibodies (TRAb) which mimic the actions of TSH are responsible for hyperthyroidism in Graves’ disease (GD) which is often associated with Graves’ orbitopathy (GO). K1-70 is a TSHR specific human monoclonal autoantibody which binds to the TSHR with high affinity and prevents stimulation of the TSHR by TSH and TRAb. Safety, tolerability, pharmacokinetic, pharmocodynamic and immunogenic effects of K1-70 in patients with GD were asse...

Objectives: The crystal structures of the TSH receptor (TSHR) leucine rich repeat domain (LRD) bound to TSHR stimulating monoclonal autoantibody M22TM or to TSHR blocking monoclonal autoantibody K1-70TM and antibody free have been solved previously. Cryo-electron microscopy (cryo-EM) was now used to solve the structure of full length TSHR in complex with K1-70TM.Methods: Recombinant human TSHR expressed in CHO cells was i...
