Estimating the term…
The present disclosure relates to antibody-drug conjugates (ADCs) wherein one or more active agents are conjugated to an anti-CD19 antibody through a linker. The linker may comprise a unit that covalently links active agents to the antibody. The disclosure further relates to monoclonal antibodies and antigen binding fragments, variants, multimeric versions, or bispecifics thereof that specifically bind CD19, as well as methods of making and using these anti-CD19 antibodies and antigen-binding fragments thereof in a variety of therapeutic, diagnostic and prophylactic indications.
1-142. (canceled)
An antibody or antigen-binding fragment thereof that binds CD19, wherein the antibody or antigen-binding fragment thereof comprises a variable heavy chain complementarity determining region 1 (CDRH1), a variable heavy chain complementarity determining region 2 (CDRH2), a variable heavy chain complementarity determining region 3 (CDRH3), a variable light chain complementarity determining region 1 (CDRL1), a variable light chain complementarity determining region 2 (CDRL2), and a variable light chain complementarity determining region 3 (CDRL3);
