Target-capture NGS provides the opportunity to evaluate many genes in a single assay. Suitability for MRD requires highly uniform and sensitive target enrichment. Our study demonstrated reliable and accurate detection of variants down to 0.05% VAF, providing researchers with the capability to use capture-based NGS for myeloid MRD monitoring.

An imidazo[1,2-a]pyridine-pyridine derivative potently inhibits FLT3-ITD and FLT3-ITD secondary mutants, including gilteritinib-resistant FLT3-ITD/F691L. (PubMed, Eur J Med Chem)

Recently, several FLT3 inhibitors have demonstrated clinical activity and three are currently approved - midostaurin, quizartinib, and gilteritinib. In summary, compound 24 has inhibition potency on FLT3 comparable to gilteritinib, but a more balanced inhibition on FLT3 secondary mutations, especially FLT3-ITD/F691L which is gilteritinib resistant. Compound 24 may serve as a promising lead for the drug development of either primary or relapsed AML with FLT3 secondary mutations.

N-(3-Methoxyphenyl)-6-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-a]pyridin-3-yl)pyridin-2-amine is an inhibitor of the FLT3-ITD and BCR-ABL pathways, and potently inhibits FLT3-ITD/D835Y and FLT3-ITD/F691L secondary mutants. (PubMed, Bioorg Chem)

Studies indicate that it mediates proapoptotic effects on cells by inhibiting FLT3 and BCR-ABL pathways, and other possible targets. Compound 1 is more potent against FLT3-ITD than BCR-ABL, and it may have other possible targets; however, compound 1 is first step for further optimization for the development of a balanced FLT3-ITD/BCR-ABL dual inhibitor for the treatment of relapsed FLT3-ITD mutated AML with multiple secondary clinical resistant subtypes such as FLT3-ITD/D835Y, FLT3-ITD/F691L, and cells co-expressing FLT3-ITD and BCR-ABL.

Since clonal heterogeneity and DNA damage are hallmarks of cancer, the "clonal attack" may be broadly applicable to the quest for cancer cure.

The Shifting Prognosis of FLT3 Mutations in Acute Myeloid Leukemia in the Era of Targeted Therapy: A Real-World Study Using Large-Scale Electronic Health Record Data (ASH 2023)

Patients were excluded if they received gilteritinib, sorafenib, or midostaurin but were diagnosed before midostaurin's approval...In a Cox regression, the interaction term was similar (HR 0.54, p = 0.021), with a HR that compared favorably to 0.78, the HR seen in phase III clinical trials studying midostaurin or quizartinib at diagnosis (Stone et al., NEJM, 2017; Erba et al., Lancet, 2023)... The relative prognosis of FLT3 mutations in AML has improved, including in older patients, likely due to the approval of FLT3 inhibitors, and the relative survival is more favorable than what was described in major clinical trials. Gathering real-world data to estimate prognosis of FLT3 mutations is crucial for accurate risk stratification, and this can be done more easily with EHR data.

Persistence of FLT3-TKD in Blood Prior to Allogeneic Transplant Is Associated with Increased Relapse and Death in Adults with AML in First Remission (ASH 2023)

Detectable persistence of FLT3-TKD variants in blood from AML patients in first remission prior to first alloHCT is rare, but at a VAF level of 0.1% was strongly associated with increased relapse and death after transplant compared to those testing negative. In contrast to FLT3-ITD NGS-MRD, no evidence was found to support lowering the NGS-MRD VAF threshold from 0.1% to 0.01% for FLT3-TKD. Alternative methodology may further improve NGS-MRD test performance.

BGS-2456 Is a Novel Potent Covalent Inhibitor of FLT3 That Highly Discriminates Against KIT and Is Not Toxic Toward Normal Hematopoiesis in Vitro (ASH 2023)

While there are numerous examples of KIT TKIs that do not inhibit FLT3 (imatinib, avapritinib, dasatinib), to date, all clinically active FLT3 TKIs (quizartinib, gilteritinib, midostaurin, sorafenib) fail to spare KIT inhibition...Compared to FF-10101 and gilteritinib, BGS-2456 exhibited the least amount of hematologic toxicity, facilitating in vitro proliferation and differentiation of normal hematopoietic progenitor cells even at 100x EC50 concentration against Molm14 cells... This is the first description of a potent and exquisitely specific FLT3 inhibitor that spares KIT inhibition and displays no myelosuppression in vitro at >100x EC50 concentration. The potent inhibitory effects of BGS-2456 on both D835Y and F691L mutants support its promise as a best-in-class TKI for the treatment of FLT3-mutant AML. Efforts to molecularly dissect the basis of the high degree of selectivity of BGS-2456 are ongoing.

Optimizing FLT3 Inhibitor Use in Adult Acute Myeloid Leukemia with FLT3 Mutations Using Proteomics (ASH 2023)

Of 137 with FLT3 ITD or D835 mutations, 54 who were treated with FLT3I (Sorafenib=22, Quizartinib=11, Midostaurine=6, Gilteritinib=4 and Crenolanib=1) combined with other agents (Hypomethylating agents (HMA)=23, HMA+Venetoclax (VTX)=5, Idarrubicin+Cytarabine (AraC)+Purine Analogs (IA+Pur)=19, IA+Pur+VTX=2, AraC=3, Fludarabine+AraC (FA)=1, none=1) were selected for analyses. Protein profiling identified cohorts of FLT3 mutant patients that achieved the highest benefit from FLT3I addition, regardless of all other clinical or molecular characteristics. We identified targetable proteins that are elevated in adverse signatures, and hypothesized that these may be targets for modulation to improve FLT3I response. Moreover, a small set of 6 proteins accurately classifies patients and could be used clinically to triage patients for treatment recommendation.

A T cell receptor targeting a recurrent driver mutation in FLT3 mediates elimination of primary human acute myeloid leukemia in vivo. (PubMed, Nat Cancer)

TCR cells rejected both CD34 and CD34 AML in mice engrafted with primary leukemia from patients, reaching minimal residual disease-negative levels, and eliminated primary CD34 AML leukemia-propagating cells in vivo. Thus, T cells targeting a single shared mutation can provide efficient immunotherapy toward selective elimination of clonally involved primary AML cells in vivo.

How acute myeloid leukemia (AML) escapes from FMS-related tyrosine kinase 3 (FLT3) inhibitors? Still an overrated complication? (PubMed, Cancer Drug Resist)

A class of drugs, tyrosine-kinase inhibitors (TKI), targeting mutated FLT3, is already available with 1 and 2 generation molecules, but only midostaurin and gilteritinib are currently approved...Indeed, FLT3 inhibitors have significantly contributed to reducing the negative impact of FLT3 mutations on the prognosis of AML patients who are no longer considered at high risk by the European LeukemiaNet (ELN) 2022. Finally, several ongoing efforts to overcome resistance to FLT3-inhibitors will be presented: new generation FLT3 inhibitors in monotherapy or combined with standard chemotherapy, hypomethylating drugs, or IDH1/2 inhibitors, Bcl2 inhibitors; novel anti-human FLT3 monoclonal antibodies (e.g., FLT3/CD3 bispecific antibodies); FLT3-CAR T-cells; CDK4/6 kinase inhibitor (e.g., palbociclib).

Rational design of 4-((6-phenoxypyrimidin-4-yl)amino)-N-(4-(piperazin-1-yl)phenyl)-1H-pyrazole-3-carboxamide (LT-540-717) as orally bioavailable FLT3 inhibitor. (PubMed, Eur J Med Chem)

Herein, we describe the discovery of compound LT-540-717 (32), a potent FLT3 inhibitor (IC: 0.62 nM), starting from FN-1501...Furthermore, 32 showed an acceptable bioavailability (F = 33.3% in rat and 72.7% in beagles), a suitable half-life time (T = 3.5 h in rat and T = 11.1 h in beagles), and a satisfactory metabolic stability. In summary, these results show the therapeutic potential of 32 to become a new anti-AML drug, especially for AML harboring dual FLT3 (ITD, TKD) mutations.

Design, synthesis and pharmacological characterization of aminopyrimidine derivatives as BTK/FLT3 dual-target inhibitors against acute myeloid leukemia. (PubMed, Bioorg Chem)

A novel class of aminopyrimidine-based Bruton's tyrosine kinase (BTK) and FMS-like tyrosine kinase 3 (FLT3) dual-target inhibitors based on the BTK inhibitor spebrutinib was designed for the treatment of acute myeloid leukemia...Finally, intraperitoneal administration of 14m at 20 mg/kg significantly repressed the growth of MV-4-11 cells with a TGI value of 95.68% with no apparent toxicity. These BTK/FLT3 dual-target inhibitors represent promising leads for further structural optimization and antitumor mechanism studies.
