ARV-825 is a hetero-bifunctional PROteolysis TArgeting Chimera (PROTAC) containing a BRD4 binding group (OTX-015) on one end, a linker arm, and a cereblon (CRBN) ubiquitin E3 ligase binding group (Pomalidomide) on the other end, resulting in BRD4 ubiquitylation and degradation by the proteasome. In Burkitt’s lymphoma cells, ARV-825 was found to cause prolonged BRD4 downregulation, reduce c-Myc levels, block cell proliferation, and induce apoptosis with improved results compared to BRD4 inihbitors such as JQ1 and OTX015. It showed similar results.
