Venetoclax + intensive chemo with CLIA

Venetoclax (Ven) added to intensive chemo with cladribine, idarubicin, and AraC (CLIA) achieves high rates of durable complete remission with low rates of measurable residual disease (MRD) in pts with newly diagnosed acute myeloid leukemia (AML)

Technology : Small molecule


18 pts are enrolled, with a median age of 50 yrs (range, 18-64). Baseline pt characteristics are in Table. 16 pts were evaluable for response and 2 are too early. 14 of 16 pts (88%) achieved a remission, including 10 (63%) complete remission (CR) and 4 (25%) CR with incomplete count recovery (CRi). The median time to response was 1 cycle and the median number of cycles given was 2 (1-5). 10 of the 14 responders (71%) had undetectable MRD at the time of remission. Both nonresponding pts had a complex karyotype and 1 had a TP53 mutation. With a median follow up of 4.5 months (0.2 – 11.2), none of the responding pts have relapsed. 8 of the 14 responders (57%) have received allogeneic stem cell transplant. The median survival has not been reached; the 6-month OS and RFS are 90% and 100%, respectively. Treatment was well tolerated, with 0% 4-week mortality. The median days to ANC ≥ 1 and Platelets ≥ 100 were 30 (19-49) and 26 (18-39), respectively. Tumor lysis syndrome was not seen. The most common adverse events were neutropenic fever, pneumonia, nausea, and liver transaminitis.


The addition of ven to CLIA was safe and effective in newly diagnosed pts with AML. The combination was not associated with early mortality or prolonged myelosuppression, but did result in high rates of durable MRD negative remissions.


Venetoclax early results in newly diagnosed patients hold promise with high response rate (ORR 90%) and no relapse at follow up of ~7 mo
