The results of this study significantly demonstrate the clinical benefit of ivosidenib (IVO) + azacitidine (AZA) compared to placebo + AZA in a difficult-to-treat AML population: the combination improved event-free survival, overall survival, and clinical response (CR, CR + CRh, ORR) in these patients with IC-ineligible, newly diagnosed mIDH1-AML. The favorable safety profile of IVO + AZA was consistent with previous studies.

Olutasidenib plus azacitidine induced durable CR/CRh in a subgroup of high-risk patients with mIDH1-AML. The combination was well tolerated. In all cohorts, some of those treated achieved transfusion independence. Further analyzes on safety and efficacy will be presented at the oral session.

SNDX-5613 demonstrated an acceptable safety profile. Promising antileukemic activity has been observed in patients with heavily pretreated R / R MLLr and mNPM1 acute leukemia. The pre-established criteria for RP2D were met with two dose levels in each arm.

The combination of gilteritinib (GIL) + azacitidine (AZA) achieved significantly higher CRc rates in the absence of new safety signals, but similar OS compared to AZA alone. Patients with ECOG PS 0-1 and high FLT3-ITD allele ratio appeared to have greater benefit with the combination. Strange: the Ctrough values in patients with ND FLT3mut + AML who were not suitable for IIC were 2 times higher than in patients with R/R FLT3mut + AML. The study results confirm the safety, tolerability and activity of the combination compared to AZA.

Induction and consolidation with fludarabine, high-dose cytarabine (Ara-C0), idarubicin and granulocyte colony-stimulating factor (G-CSF) plus venetoclax (FLAG-IDA + VEN) leads to high MRD-negative CRc rates in ND-AML with an expected safety profile. After one year there was a sustained response with favorable results compared to historical cohorts of intensive therapy. With TP53 mutations there were inferior outcomes in comparison to wild-type TP53.

HM43239 is a preclinically effective FLT3 and SYK inhibitor. In the present study, the substance showed a favorable safety profile with only slight undesirable side effects and no redefining dose-limiting toxicity (DLT). At 80 mg, HM43239 shows clinical activity in both FLT3m and FLT3wt-AML. Updated data on response, safety and PK / PD will be presented in the oral session.
