Overview

SHR-A1912 + rituximab + chemotherapy is a combination therapy comprising SHR-A1912 (an anti-CD79b antibody-drug conjugate linked to a DNA topoisomerase I inhibitor), the monoclonal antibody rituximab (targets CD20 on B cells), and various cytotoxic chemotherapy agents. This regimen is being evaluated primarily for B-cell non-Hodgkin's lymphoma, including diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), and marginal zone lymphoma (MZL). SHR-A1912 is developed by Jiangsu HengRui and is designed to deliver potent cytotoxic effects directly to CD79b-expressing malignant B cells. Rituximab depletes B cells by targeting CD20, while the chemotherapy component (regimens such as GemOx or CHOP) offers additional cytotoxicity through diverse mechanisms. The combination aims to increase tumor cell kill rates by leveraging targeted immunotherapy and chemotherapy synergistically[1][3][5][9].
