- (a) administering an antibody construct that binds selectively to a target antigen on a cancer cell and to human CD3 on the surface of a T cell,
- (b) administering an inhibitor/antagonist of TNF/TNFR reducing TNF/TNFR signaling, and/or administering an inhibitor/antagonist of IL6/IL6R that reduces IL6/IL6R signaling,
- wherein a first dose of said inhibitor/antagonist of TNF/TNFR that reduces TNF/TNFR signaling and/or a first dose of said inhibitor/antagonist of IL6/IL6R that reduces IL6/IL6R according to (b) signaling is administered before administration of a first dose of said antibody construct (a) within a first period, said period ranging from 5 minutes to 7 days prior to administration of the antibody construct, particularly wherein said period is ranging from 15 minutes to 7 days prior to administration of the antibody construct.
