Compositions and methods relating to regulatable chimeric antigen receptors (RCARs), where the intracellular signaling or proliferation of the RCAR can be controlled to optimize the use of an RCAR-expressing cell to provide an immune response, are provided. For example, a RCAR can comprise a dimerization switch that, upon the presence of a dimerization molecule, can couple an intracellular signaling domain to an extracellular recognition element, e.g., an antigen binding domain, an inhibitory counter ligand binding domain, or costimulatory ECD domain. An RCAR can be engineered to include an appropriate antigen binding domain that is specific to a desired antigen target and used in the treatment of a disease.

The present invention provides a method for preparation of a lyophilized formulation of an anti-CD 20 antibody as well as to a lyophilized formulation of an anti-CD 20 antibody, comprising an anti-CD 20 antibody and having a residual moisture content in the range of 1% to 10%. The present invention also relates to the reconstituted formulation obtained by the method described herein, the use of said antibody formulation as a medicament, the use of the lyophilized formulation for the preparation of a medicament and a method of treating a patient.

The present invention relates generally to an isolated antibody which specifically binds human CD137, and pharmaceutical compositions and methods of use thereof, a nucleic acid comprising a nucleotide sequence encoding said antibody, a vector comprising said nucleic acid, a host cell comprising said nucleic acid or said vector, and a method of producing said antibody.

The present disclosure provides immunogenic compositions comprising: a) hepatitis C virus (HCV) E1E2 heterodimers, HCV E2, or HCV E1; and b) an adjuvant, where the adjuvant is a cyclic dinucleotide or an archaeosome. The present disclosure provides methods of inducing an immune response in an individual to HCV, the methods comprising administering to an individual an effective amount of an immunogenic composition of the present disclosure.

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.
