Mezigdomide (BMS-986348)
Mechanism of action
From the NCI Drug Dictionary: A modulator of the E3 ubiquitin ligase complex containing cereblon (CRL4-CRBN E3 ubiquitin ligase), with potential immunomodulating and antineoplastic activities. Upon administration, mezigdomide specifically binds to cereblon (CRBN), thereby affecting the ubiquitin E3 ligase activity, and targeting certain substrate proteins for ubiquitination. This induces proteasome-mediated degradation of certain transcription factors, some of which are transcriptional repressors in T cells. This leads to modulation of the immune system, including activation of T lymphocytes, and downregulation of the activity of other proteins, some of which play key roles in the proliferation of certain cancer cell types.
Preliminary data
