|---|---|---|---|---|---|---|---|
| TET2 loss | leukemia | sensitive | TETi76 | Preclinical - Cell line xenograft | Actionable | In a preclinical study, TETi76 treatment reduced viability and colony formation of a TET2-null leukemia cell line in culture, decreased viability of bone marrow derived mononuclear cells from TET2-null mouse model, and reduced tumor burden in a TET2-null subcutaneous xenograft model (PMID: 33681816). | 33681816 |
| TET2 loss | acute myeloid leukemia | sensitive | Olaparib | Preclinical - Cell culture | Actionable | In a preclinical study, Lynparza (olaparib) inhibited colony formation in mouse acute myeloid leukemia cells harboring TET2 loss along with various oncogenic tyrosine kinase mutations in culture (PMID: 34215619). | 34215619 |
| TET2 loss | acute myeloid leukemia | sensitive | Talazoparib | Preclinical - Cell culture | Actionable | In a preclinical study, Talzenna (talazoparib) decreased colony formation in mouse acute myeloid leukemia cells harboring TET2 loss along with a FLT3-ITD mutation in culture (PMID: 34215619). | 34215619 |
