Abexinostat (INN,[1] formerly PCI-24781) is an experimental drug candidate for cancer treatment.[2] It was developed by Pharmacyclics and licensed to Xynomic. As of 2013, it was in Phase II clinical trials for B-cell lymphoma.[3][needs update] Pre-clinical study suggests the potential for treatment of different types of cancer as well.[4][5][6][7]

Abexinostat exerts its effect as a pan-histone deacetylase inhibitor[8][9] and inhibits RAD51, which is involved in repairing DNA double strand breaks.[10]
