Venetoclax (formerly known as ABT-199 or GDC-0199; Venclexta) is a potent, selective and orally bioavailable small molecule inhibitor of the anti-apoptotic protein BCL-2 (B-cell lymphoma-2) with Ki of<0.01 nM. On April 11, 2016, the FDA authorized venetoclax for use in CLL patients who have a 17p deletion (a deletion on the short arm of chromosome 17) and who have received at least one prior therapy. Venetoclax works as a BCL-2 inhibitor by mimicking BH3, which is the native ligand of BCL-2. It prevents the anti-apoptotic BCL-2 protein, causing CLL cells to undergo programmed cell death.
| Targets |
Bcl-2 (Ki = 0.01 nM); Bcl-xL (Ki = 48 nM); Bcl-W (Ki = 245 nM)

| ln Vitro |
ABT-199 shows less sensitivity to Bcl-xL, Mcl-1 and Bcl-w with Ki of 48 nM, > 444 nM and 245 nM, respectively. ABT-199 exhibits weak activity against FL5.12-Bcl-xL cells with an EC50 of 261 nM, but potently inhibits FL5.12-Bcl-2 cells, RS4;11 cells with EC50s of 4 nM and 8 nM. In RS4;11 cells, ABT-199 causes a rapid apoptosis that is accompanied by the release of cytochrome c, activation of caspase, externalization of phosphatidylserine, and accumulation of sub-G0/G1 DNA. According to quantitative immunoblotting, Bcl-2 expression was strongly correlated with ABT-199 sensitivity in cell lines from NHL, DLBCL, MCL, AML, and ALL. The average EC50 for ABT-199 inducing apoptosis in CLL is 3.0 nM. [1]
|
| ln vivo |
ABT-199 (100 mg/kg) causes a maximal tumor growth inhibition of 95% and tumor growth delay of 152% in RS4;11 xenografts. ABT-199 can be used alone or in combination with other drugs, such as SDX-105, to inhibit the growth of xenografts (DoHH2, Granta-519). [1]

| Enzyme Assay |
Binding affinities (Ki or IC50) of ABT-199 against different isoforms of Bcl-2 family are determined with competitive fluorescence polarization assays. The peptide probe and protein pairs used are as follows: : f-bad (1 nM) and Bcl-xL (6 nM), f-Bax (1 nM) and Bcl-2 (10 nM), f-Bax (1 nM) and Bcl-w (40 nM), f-Noxa (2 nM) and Mcl-1 (40 nM), and f-Bax (1 nM) and Bcl-2-A1 (15 nM). A time-resolved fluorescence resonance energy transfer assay is also used to determine the binding affinities for Bcl-xL. At room temperature, for 30 minutes, Bcl-xL (1 nM, His tagged), 200 nM f-Bak, 1 nM Tb-labeled anti-His antibody, and ABT-199 are combined.
|
| Cell Assay |
RS4;11 cells are treated with ABT-199 diluted in half-log steps starting at 1 μM-0.05 nM after being seeded at a density of 5 × 104 per well in 96-well plates. ABT-199 is incubated with leukemia and lymphoma cell lines for 48 hours after they have been seeded at 1.5-2 × 104 cells per well in the appropriate medium. Using the Cell TiterGlo reagent, effects on proliferation are assessed. The concentration-response data are analyzed using nonlinear regression to determine the EC50 values.

| Animal Protocol |
Mice: Nonobese diabetic/severe combined immunodeficient γ (NSG) mice are given a 150 µL injection of phosphate-buffered saline containing 5×106 luciferase-labeled LOUCY cells at the age of 6 weeks in the tail vein.
The IVIS Lumina II imaging system measures the bioluminescence at regular intervals. After the cells have engrafted and the mice have been randomly split into two groups at 6 weeks (each group contains an equal number of males and females), the treatment is initiated on day 0 of the experiment. Venetoclax (ABT-199) 100 mg/kg body weight or vehicle is administered orally to mice for 4 days in a row. Days 0, 2, and 4 are used to measure the bioluminescene.
