Hematological cells response to S63845, trametinib, and combination treatment. Cell viability assessments in mononuclear cells of AML (A), other hematological malignancies (B), and normal cells treated for 20 h with S63845 and trametinib alone or in combination. All values are in reference to mock treated cells (= 100% viability). Statistical significance is indicated for the effects of single versus combination treatments. (C) Clinical characteristics of the AML and other hematological malignancies. Acute myeloid leukemia (AML), acute lymphatic leukemia (ALL), chronic lymphatic leukemia (CLL), chronic myeloid leukemia (CML), B-cell lymphoma (BCL), mantle cell lymphoma (MCL). Peripheral blood (PB), bone marrow (BM), normal karyotype (NK), complex karyotype (CK). Relapsed/refractory (R/R). Susceptibility of grouped AML subsets to trametinib (D), S638 (E), and combination treatment (F). Significance is denoted for p < 0.05 (*); p < 0.005 (**); p < 0.0005 (***); p > 0.05 (ns).
