Anaplastic thyroid cancers (ATC) are fast-growing, undifferentiated tumors and almost invariably fatal, primarily due to the lack of effective therapeutic options. The recent approval of dabrafenib plus trametinib for the treatment of BRAFV600E-mutant ATCs improved the prognosis of a subset of patients, but ineligibility and acquired resistance still limit their use. Overall, ATC patients remain in great need of tailored therapeutic options. We previously showed that loss-of-function alterations targeting histone acetyltransferase (HAT) genes, namely CREBBP and EP300, occur in 15-20% of ATCs, but only in Citation Format: Jacob Haase, Talia A.
