In recent years, however, a number of drugs have received FDA approval, following on from successful clinical trial results. This parallels the characterization of the molecular landscape of Acute Myeloid Leukaemia (AML) over the last decade, which has led to the development of MEK1/2 inhibition by binimetinib is effective as a single agent and potentiates the actions of Venetoclax and ABT-737 under conditions that mimic the chronic lymphocytic leukaemia (CLL) tumour microenvironment ABT-737, ABT-263 (Navitoclax) and ABT-199 (Venetoclax) are under intensive preclinical and clinical investigation as treatments for hematologic and other malignancies.

These small molecules mimic pro-death B-cell lymphoma-2 (Bcl-2) Homology 3 (BH3) domain-only proteins. Venetoclax (Venclexta®) is a first-in-class selective Bcl-2 inhibitor approved for the treatment of chronic lymphociytic leukemia (1). Venetoclax1(Figure 1) disrupts blockage of the intrinsic apoptosis pathway mediated by Bcl-2 family proteins. CT26 cells were treated with ABT-737 or S55746 (1 μM for 24 h) and analysed for OCR by Seahorse assay (Fig. 3a, b). Unlike venetoclax, neither ABT-737 nor S55746 decreased OCR. Description: ABT-737 is a novel, potent, selective and orally available BH3 mimetic inhibitor of Bcl-xL, Bcl-2 and Bcl-w with EC50 of 78.7 nM, 30.3 nM and 197.8 nM in enzymatic assays, respectively.

The MV4-11 ABT-199R clones also demonstrated co-resistance to ABT-737 (BCL-2 and BCL-XL inhibitor), S63845 (MCL-1 inhibitor), and S55746 (BCL-2 inhibitor). Venetoclax plus LDAC demonstrates clinically meaningful improvement in remission rate and OS vs LDAC alone, with a manageable safety profile. Results confirm venetoclax plus LDAC as an important frontline treatment for AML patients unfit for intensive chemotherapy.

These small molecules mimic pro-death B-cell lymphoma-2 (Bcl-2) Homology 3 (BH3) domain-only proteins. Furthermore, binimetinib significantly increased the sensitivity of CLL cells co-cultured with CD40 ligand (CD40L)-expressing fibroblasts to the BH3-mimetics ABT-737 and Venetoclax (ABT-199) via a mechanism involving down-regulation of Mcl-1 (MCL1) activity and Bim (BCL2L11) and Bcl-xL (BCL2L1) expression.

Venetoclax (ABT-199) is an unusual drug. AbbVie perservered, even after its original molecule in the field (ABT-737) ran into trouble in the clinic with effects on platelets. Primary AML blasts were treated with cobimetinib and venetoclax alone or in combination at 0.1 μM for 5 days in LSC medium to maintain the immature state of the leukemia cells.24 Cobimetinib alone induced minimal cell death (specific apoptosis, 6.7 ± 5.9%), which was significantly enhanced when the drug was given in combination with venetoclax (27.7 ± 20.2%, P=0.001) (Figure 2A, left). Venetoclax plus LDAC demonstrates clinically meaningful improvement in remission rate and OS vs LDAC alone, with a manageable safety profile. Results confirm venetoclax plus LDAC as an important frontline treatment for AML patients unfit for intensive chemotherapy.
