Abstract: Provided herein are populations of anti-CD20 antibody proteins with specified ranges of post-translational modifications. Also provided are methods of using and methods of making such populations of anti-CD20 antibody proteins.

Abstract: Methods for treating B-cell malignancies are provided comprising administering a triple combination of agents, comprising: (i) a PI3K-delta selective inhibitor (e.g., umbralisib); (ii) an anti-CD20 antibody (e.g., ublituximab); and (iii) the Bruton's tyrosine kinase (BTK) inhibitor TG-1701. Kits for carrying out the claimed methods are also provided.

Abstract: Methods for inhibiting proliferation of a B-cell population are provided comprising administering a combination of agents, comprising: (i) at least one P13K-delta selective inhibitor; (ii) at least one anti-CD20 antibody; and (iii) at least one Bruton's tyrosine kinase (BTK) inhibitor. Methods for treating B-cell proliferative disorders, such as B-cell hematological malignancies, as well as kits for carrying out the claimed methods, are also provided.
