Avadomide (CC-122)，一种新型的多效性修饰剂化合物，在弥漫性大B细胞淋巴瘤（DLBCL）中具有抗肿瘤、免疫调节活性。其分子靶标为cereblon (CRBN)，CRBN是E3泛素化连接酶复合体CRL4CRBN的底物受体。 Information Avadomide (CC-122) Avadomide (CC-122), a new chemical entity termed pleiotropic pathway modifier, is a novel agent for Diffuse large B-cell lymphoma(DLBCL) with antitumor and immunomodulatory activity. Its molecular target is the protein cereblon (CRBN), a substrate receptor of the cullin ring E3 ubiquitin ligase complex CRL4 CRBN . Targets CRBN In vitro CC-122 is a novel agent for DLBCL with antitumor and immunomodulatory activity. In DLBCL cell lines, It binds CRBN and induces degradation or short hairpin RNA-mediated knockdown of Aiolos and Ikaros which correlates with increased transcription of interferon (IFN)-stimulated genes independent of IFN-α, -β, and -γ production and/or secretion and results in apoptosis in both activated B-cell (ABC) and germinal center B-cell DLBCL cell lines. CRBN is the molecular target of CC-122, CC-122 binding to CRBN recruits Aiolos/Ikaros to CRL4 CRBN , and E3 ligase enzymatic activity is necessary for ubiquitination of Aiolos and Ikaros and thus their proteasomal degradation induced by CC-122. CC-122 induces IFN-regulated proteins and its mediated effects on the IFN pathway is independent of autocrine type I and II IFN secretion and signaling. In vivo CC-122 reduces tumor growth in xenograft models established from ABC- and GCB-DLBCL cell lines, and stimulates IL-2 production in primary T cells. Also, in a single-arm CC-122 clinical trial, exposure to CC-122 reduced expression levels of Aiolos and Ikaros in each patient by 25% to 50% demonstrating the utility of these 2 proteins as pharmacodynamic markers of CC-122.
