Diagnostic AML blasts from patient 7 [46, XY, t(8;21)], THP-1, and Kasumi-1 cells cultured in RPMI1640 plus 10–20% FBS were treated with VPA (0.5, 0.66, and 0.5 mM, respectively) or cytarabine (1000, 900, and 100 nM, respectively) alone or in combination for 24 h (for the patient sample) or 96 h (for the cell lines). The VPA and cytarabine doses for the cell lines were IC20s, while those for patient AML blasts were ~IC50s, determined by MTT assays. The same concentrations of VPA and cytarabine were used in the rest of the studies unless specified. The cells were harvested, vigorously pipetted and triplicate samples taken to determine baseline and drug-induced apoptosis using the Apoptosis Annexin-V fluorescein isothiocyanate (FITC)/propidium iodide (PI) Kit (Beckman Coulter; Brea, CA), as previously described.29 (link) Apoptotic events were recorded as a combination of Annexin-V+/PI- (early apoptotic) and Annexin-V+/PI+ (late apoptotic/dead) events and results were expressed as percent of Annexin-V+ cells after subtracting results for untreated cells. Synergy was quantified using the cooperativity index (cooperativity index = sum of apoptosis of single agent treatment/apoptosis upon combined treatment). Cooperativity index <1, =1, or >1 is termed synergistic, additive, or antagonistic, respectively.23 (link)

We obtained samples from patients participating in three prospective multicenter clinical trials of the German–Austrian AML Study Group: AML-HD98A, AML-HD98B, and AMLSG-07-04 (see the Supplementary Appendix, available with the full text of this article at NEJM.org).9 (link)–11 (link) In AML-HD98A, patients 18 to 65 years of age received induction chemotherapy consisting of idarubicin, cytarabine, and etoposide (ICE); high-risk patients were offered allogeneic stem-cell transplantation, intermediate-risk patients a stem-cell allograft (if a matched related donor was available) or intensive chemotherapy, and low-risk patients intensive chemotherapy. AMLSG-07-04 had a similar design, but patients 18 to 61 years of age were randomly assigned to receive ICE or ICE plus all-trans retinoic acid (ATRA) as induction therapy. In AML-HD98B, patients 58 to 84 years of age were randomly assigned to induction therapy with ICE or ICE plus ATRA, with further therapy dictated by the response (see Figs. S1 and S2 in the Supplementary Appendix). The median follow-up period was 5.9 years (Table S1 in the Supplementary Appendix). All patients provided written informed consent.
The last two authors guided the analysis and data interpretation.

In vitro cytarabine and VPA cytotoxicities of pediatric AML cell lines and diagnostic blasts were measured by using MTT (3-[4,5-dimethyl-thiazol-2-yl]-2,5-diphenyltetrazolium-bromide, Sigma) assays, as previously described.26 (link) IC50 values were calculated as drug concentrations necessary to inhibit 50% proliferation compared to untreated control cells. The extent and direction of cytarabine and VPA cytotoxic interactions were evaluated as described previously.27 (link),28 (link) Briefly, synergism, additivity or antagonism was quantified by determining the combination index (CI), where CI<1, CI=1, and CI>1 indicate synergistic, additive, and antagonistic effects, respectively. Based on the classic isobologram, the CI was calculated using the following equation: CI=[(D)1/(Dx)1] + [(D)2/(Dx)2]. At the 50% inhibition level, (Dx)1 and (Dx)2 are concentrations of cytarabine and VPA, respectively, which induce a 50% inhibition in cell proliferation when administered individually. (D)1 and (D)2 are concentrations of cytarabine and VPA, respectively, which inhibit cell proliferation by 50% when combined.

Patients who consented to the optional therapeutic window were randomized to receive upfront methotrexate over 4 or 24 hours. Four days after methotrexate treatment, remission induction therapy began with prednisone, vincristine, daunorubicin, and asparaginase (Table 1). Patients with ≥ 1% MRD on day 19 received three additional doses of asparaginase. Subsequent induction therapy consisted of cyclophosphamide, mercaptopurine and cytarabine. Upon hematopoietic recovery (between days 43 and 46), MRD was assessed, and consolidation therapy began (Table 1).

During initial continuation therapy (Table 1), low-risk cases received daily mercaptopurine and weekly methotrexate with pulses of mercaptopurine, dexamethasone and vincristine. Two reinduction treatments were given between weeks 7–9 and weeks 17–19. Standard-risk cases received weekly asparaginase and daily mercaptopurine with pulses of doxorubicin plus vincristine plus dexamethasone. They also received two reinduction treatments between weeks 7–9 and weeks 17–20.
For the remaining continuation therapy (Supplementary Table 1), low-risk patients received mercaptopurine and methotrexate, with pulses of dexamethasone, vincristine and mercaptopurine, and standard-risk patients received three rotating drug pairs (mercaptopurine plus methotrexate, cyclophosphamide plus cytarabine, and dexamethasone plus vincristine). Dosages of mercaptopurine and methotrexate were adjusted according to the tolerance, and thiopurine methyltransferase phenotype and genotypes.17 (link) Total scheduled dosages of anthracyclines and cyclophosphamide were limited to 110 mg/m2 and 230 mg/m2, and 1 g/m2 and 4.6 g/m2, for low-risk and standard-risk patients, respectively. Continuation treatment lasted 120 weeks in girls and 146 weeks in boys.

Thawed primary human AML blasts were cultured on irradiated stromal feeder cell layers with cytokine- and SR1- (1uM) supplemented media. Live blast purification was achieved by magnetic bead-based dead cell removal prior to culture (Miltenyi # 130-090-101). Fresh media was added every 2–3 days and cells were re-plated prior to reaching 70–80% confluence. After 12 h of preconditioning, IACS-010759, diluted in DMSO, was added to a final concentration of 30 nM. Similarly, Cytarabine, diluted in PBS, was added to a final concentration of 100 ng/ml. Equivalent volumes of PBS and DMSO were added to the mock-treated conditions. Cells were harvested at Day 5 post-culture and analyzed by flow cytometry and transplanted into recipient-irradiated female NSG mice.

For chemotherapy experiments, mice (NSGW41) were treated with 1.5 mg/kg Daunorubicin hydrochloride (Pfizer) by tail vein injection on days 1, 2, and 3. Cytarabine (Hospira) was administered at a dose of 60 mg/kg by subcutaneous injection on days 1 to 5 of the treatment regimen. Both drugs were prepared in saline and mice weight was checked daily for proper dosing. Control animals received equal dose of saline solution. Mice were allocated to treatment or control groups with equal AML burden based on a pre-treatment bone marrow aspirate evaluation of human AML chimerism. Litter mates were divided into both groups. For EdU (5-ethynyl-2′-deoxyuridine) incorporation assays, mice received daily intraperitoneal injections of EdU (ThermoFisher Scientific # E10187, 50 mg/kg body weight) from day 4 to day 7 of the in vivo treatment cycle.

As described in our previous studies, induction chemotherapy was started with a modified regimen of fractionated cyclophosphamide, vincristine, doxorubicin, dexamethasone (hyper-CVAD), and alternating high-dose cytarabine and mitoxantrone.22 (link)25 (link, link, link) Patients who failed to achieve CR or relapsed after CR received intensified salvage chemotherapy using an MEC regimen consisting of cytarabine (2 g/m2, every 12 h, days 1–4), mitoxantrone (12 mg/m2, days 1–4), and etoposide (100 mg/m2, days 5–7). Patients with Ph-positive ALL also received tyrosine kinase inhibitors (imatinib or dasatinib).24 (link)28 (link, link, link, link) In patients who revealed minimal residual disease (MRD) at 3 months post-transplant, we applied preemptive tyrosine kinase inhibitors. Since 2016, blinatumomab was used as a monotherapy for all above indications instead of MEC regimen in the same way of our previous study.21 (link) Before application of blinatumomab, all patients received prephase dexamethasone to reduce leukemic burden and cytokine release syndrome (CRS). During the first cycle, blinatumomab was continuously infused for 4 weeks (9 μg/day for the first 7 days and 28 μg/day thereafter). After a 2-week treatment-free interval, a second 4-week cycle was initiated at a dosage of 28 μg/day from day 1 to day 28. Even after 2016, we applied the MEC regimen to some patients who failed to blinatumomab, while some others were treated with inotuzumab ozogamicin (INO) as it became available for R/R Ph-negative ALL since late 2019.29 ,30 (link) Doses of INO were administered at 0.8 mg on day 1 of the first cycle (0.5 mg on the day of the second cycle) and 0.5 mg on days 8 and 15. The interval of the first cycle was 28 days, and up to two cycles were approved.
