GA101 (a Novel Anti-CD20 Monoclonal Antibody)-Induced Lichenoid Eruption

INTRODUCTION Obinutuzumab (GA101) is a novel anti-CD20 monoclonal antibody that has been shown to be effective for the treatment of non-Hodgkin's lymphoma, and is currently being evaluated in phase 3 clinical trials. The side-effect profile of the drug is not yet well established. CASE REPORT The authors report a case of a 62-year-old patient who developed widespread lichenoid eruption as a r...

Ofatumumab: a novel monoclonal anti-CD20 antibody

Ofatumumab, a novel humanized monoclonal anti-CD20 antibody, was recently approved by the FDA for the treatment of fludarabine and alemtuzumab refractory chronic lymphocytic leukemia (CLL). Ofatumumab effectively induces complement-dependent cytotoxicity (CDC) in vitro, and recent studies demonstrated that ofatumumab also effectively mediates antibody-dependent cellular cytotoxicity (ADCC). Pha...

Development of a Novel Inhibitory Chimeric Anti-HER2 Monoclonal Antibody

Preclinical studies on the mechanism of action and the anti-lymphoma activity of the novel anti-CD20 antibody GA101.

GA101 is a novel glycoengineered Type II CD20 monoclonal antibody. When compared with rituximab, it mediates less complement-dependent cytotoxicity (CDC). As expected for a Type II antibody, GA101 appears not to act through CDC and is more potent than the Type I antibody rituximab in inducing cell death via nonclassical induction of apoptosis cytotoxicity, with more direct cytotoxicity and more...

production and characterization of new anti-human cd20 monoclonal antibody

the b-cell cd20 antigen is one of the most reliable surface targets in immunotherapy of b lymphoma. in this project, we studied the production and characterization of a new monoclonal antibody against chimeric human cd20 extra loops (hcd20 exl). the results showed that clone c12h, igg2/k isotype reacted with the antigen in elisa and immunoblot. the kd value was  found to be 2×10-9m and flow cyt...
