Overview

POLA-Hi-CHP + orelabrutinib is an investigational chemoimmunotherapy combination regimen being evaluated for the treatment of the MCD subtype of diffuse large B-cell lymphoma (DLBCL). The regimen consists of the antibody-drug conjugate **polatuzumab vedotin** (targeting CD79b), the anti-CD20 monoclonal antibody **zuberitamab**, the chemotherapy agents **cyclophosphamide** and **doxorubicin**, the corticosteroid **prednisone**, and the small-molecule Bruton's tyrosine kinase (BTK) inhibitor **orelabrutinib**. This combination targets multiple pathways in B-cell malignancies, including B-cell receptor signaling and direct cytotoxic effects. It is specifically studied in the MCD subtype (defined by MYD88 and CD79B mutations), which often shows sensitivity to BTK inhibition. The regimen is typically administered as induction therapy followed by orelabrutinib monotherapy maintenance.
