The present invention provides multispecific antigen-binding molecules and uses thereof. The multispecific antigen-binding molecules comprise a first antigen-binding domain that specifically binds a target molecule, and a second antigen-binding domain that specifically binds an internalizing effector protein. The multispecific antigen-binding molecules of the present invention can, in some embodiments, be bispecific antibodies that are capable of binding both a target molecule and an internalizing effector protein. In certain embodiments of the invention, the simultaneous binding of the target molecule and the internalizing effector protein by the multispecific antigen-binding molecule of the present invention results in the attenuation of the activity of the target molecule to a greater extent than the binding of the target molecule alone. In other embodiments of the invention, the target molecule is a tumor associated antigen, and the simultaneous binding of the tumor associated antigen and the internalizing effector protein by the multispecific antigen-binding molecule of the present invention causes or facilitates the targeted killing of tumor cells.

The invention relates to a liquid pharmaceutical formulation comprising an antibody or antigen-binding fragment thereof, cyclodextrin and methionine. In addition, it relates to a method for reducing precipitation of an antibody or an antigen-binding fragment thereof in a liquid pharmaceutical formulation through addition of methionine and cyclodextrin. In particular, the liquid pharmaceutical formulations comprises an anti-sclerostin antibody, hydroxypropyl-gamma cyclodextrin and methionine and may be used in the treatment of a bone disorder associated with at least one of low bone formation, low bone mineral density, low bone mineral content, low bone mass, low bone quality and low bone strength, and especially for treating osteoporosis. Furthermore, the invention relates to a method of reducing inflammation at injection site in a mammalian subject comprising administering a therapeutically effective amount of a liquid pharmaceutical formulation comprising an antibody or antigen-binding fragment thereof, cyclodextrin and methionine.

Bispecific antibodies which comprise one antigen-binding region binding to an epitope of human epidermal growth factor receptor 2 (HER2) and one antigen-binding region binding to human CD3, and related antibody-based compositions and molecules, are disclosed. Pharmaceutical compositions comprising the antibodies and methods for preparing and using the antibodies are also disclosed.
