Ublituximab

TG Therapeutics, Inc.

Drug Names(s): LFB-R603, TG-1101, TG20, TGTX-1101, Utuxin

Description: LFB-R603 is a chimeric anti-CD20 recombinant monoclonal antibody directed towards the CD20 antigen expressed on the surface of B cells. The specific glycosylation profile of LFB-R603 gives it powerful ADCC (antibody-dependent cell-mediated cytotoxicity) activity directed against the tumor cells carrying this antigen. This exceptional high cytotoxicity has been demonstrated in non-clinical studies performed in vitro and in vivo experimental models.

TG Therapeutics is developing TG-1101 in combination with TGR-1202 under its 1303 program, seen here.
