The Immunomodulatory Effect of Different FLT3 Inhibitors on Dendritic Cells. (PubMed, Cancers (Basel))
Our results suggest different immunosuppressive effects of these three FLT3i and may, therefore, provide an additional rationale for optimal maintenance therapy after alloHSCT of FLT3-positive AML patients to prevent infectious complications and GvHD mediated by DCs.

T/NK Cell-Associated Transcriptomic Profile Informs Response to FLT3 Inhibitors in Acute Myeloid Leukemia (ASH 2024)
We then profiled a wet-lab cohort of 37 FLT3-mut AML patients treated either with Midostaurin plus chemotherapy (M) or Gilteritinib (G) at Bologna Hematology Institute by using the PanCancer IO 360 Panel (NanoString Technologies, San Diego, CA). This study provides evidence that FLT3 mutational status is associated with a unique T-cell activation profile and AML maturation state, and that T/NK cell-associated genes correlate with response to FLT3i. Our RNA metric of FLT3 mutational status could be utilized to refine patient stratification in future clinical trials. S.R.

Midostaurin shapes macroclonal and microclonal evolution of FLT3-mutated acute myeloid leukemia. (PubMed, Blood Adv)
Considering both treatment groups, if only 24% of FLT3-ITD microclones detected at diagnosis were retained at relapse, 43% of them became macroclones. Together, these results identify parameters influencing the fitness of FLT3-ITD clones and highlight the importance of using sensitive techniques for FLT3--ITD screening in clinical practice.

In silico and in vitro study of FLT3 inhibitors and their application in acute myeloid leukemia. (PubMed, Mol Med Rep)
The present study aimed to gain insights into the molecular interactions and affinity forces of four TKI drugs (sorafenib, midostaurin, gilteritinib and quizartinib) with the wild‑type (WT)‑FLT3 and ITD‑mutated (ITD‑FLT3) structural models of FLT3, in its inactive aspartic acid‑phenylalanine‑glycine motif (DFG‑out) and active aspartic acid‑phenylalanine‑glycine motif (DFG‑in) conformations. Thus, the current study presented novel information about molecular interactions between the FLT3 receptors (WT or ITD‑mutated) and some of their inhibitors. It also paves the way for the search for novel inhibitory molecules with potential use against AML.

Midostaurin added to 10-day decitabine, for patients unfit for intensive chemotherapy with AML and higher risk MDS, irrespective of FLT3 mutational status, does not improve outcome. (PubMed, Ann Hematol)
In the decitabine plus midostaurin arm 24% reached CR/CRi, the median OS was 4.8 months and 1-yrs OS was 31% which compared with 34% CR/CRi, median OS of 7.4 months and 1-yrs OS of 37% for the decitabine alone group (NS). Thus, while the addition of midostaurin appears safe, it does not enhance therapeutic efficacy of decitabine in unfit AML patients.

Tracking Response and Resistance in Acute Myeloid Leukemia through Single-Cell DNA Sequencing Helps Uncover New Therapeutic Targets. (PubMed, Int J Mol Sci)
For Pt #1, disease resistance was associated with clonal expansion of minor clones, and 2nd line TKI therapy with gilteritinib provided a proliferative advantage to the clones carrying NRAS and KIT mutations, thereby responsible for relapse. In Pt #2, clonal architecture was less complex, and 1st line TKI therapy with midostaurin was able to eradicate the leukemic clones. Our results corroborate previous findings about clonal selection driven by TKIs, highlighting the importance of a deeper characterization of individual clonal architectures for choosing the best treatment plan for personalized approaches aimed at optimizing outcomes.

Current status and research directions in acute myeloid leukemia. (PubMed, Blood Cancer J)
Since 2017, twelve agents have been approved for the treatment of AML subsets: the BCL2 inhibitor venetoclax; the CD33 antibody drug conjugate gemtuzumab ozogamicin; three FLT3 inhibitors (midostaurin, gilteritinib, quizartinib); three IDH inhibitors (ivosidenib and olutasidenib targeting IDH1 mutations; enasidenib targeting IDH2 mutations); two oral hypomethylating agents (oral poorly absorbable azacitidine; fully absorbable decitabine-cedazuridine [latter approved as an alternative to parenteral hypomethylating agents in myelodysplastic syndrome and chronic myelomonocytic leukemia but commonly used in AML]); and CPX-351 (encapsulated liposomal 5:1 molar ratio of cytarabine and daunorubicin), and glasdegib (hedgehog inhibitor)...To achieve optimal results in such a rare and heterogeneous entity as AML requires expertise, familiarity with this rare cancer, and the access to, and delivery of disparate therapies under rigorous supportive care conditions. In this review, we update the standard-of-care and investigational therapies and outline promising current and future research directions.

Enhancing Therapeutic Efficacy of FLT3 Inhibitors with Combination Therapy for Treatment of Acute Myeloid Leukemia. (PubMed, Int J Mol Sci)
The advent of FLT3 tyrosine kinase inhibitors (TKIs), such as midostaurin and gilteritinib, has shown promise in achieving complete remission. Specifically, we provide evidence for integrating gilteritinib with mammalian targets of rapamycin (mTOR) inhibitors and interleukin-15 (IL-15) complexes. The combination of gilteritinib, mTOR inhibitors, and IL-15 complexes presents a compelling strategy to enhance the eradication of AML blasts and enhance NK cell killing, offering a potential for improved patient outcomes.

Outcomes with single-agent gilteritinib for relapsed or refractory FLT3-mutant AML after contemporary induction therapy. (PubMed, Blood Adv)
Gilteritinib is the current standard of care for relapsed or refractory FLT3-mutated AML in many countries, however outcomes for patients relapsing after contemporary first-line therapies (intensive chemotherapy with midostaurin, or non-intensive chemotherapy with venetoclax) are uncertain. Twenty patients received gilteritinib as first salvage having progressed following first-line therapy with venetoclax, with CR/CRi achieved in 25% and median survival 4.5 months. Real-world results with gilteritinib mirror those seen in the clinical trials but outcomes remain suboptimal, with more effective strategies needed.

Maintenance Therapy in Acute Myeloid Leukemia. (PubMed, Am J Clin Oncol)
Hypomethylating agents like azacitidine and decitabine have shown promise in improving relapse-free and overall survival, particularly in older patients with AML ineligible for transplantation. Combination regimens involving azacitidine and venetoclax have demonstrated encouraging outcomes post-hematopoietic stem cell transplantation. Targeted therapies, particularly FLT3 inhibitors like midostaurin and quizartinib, have shown significant benefits in improving survival outcomes, especially in FLT3-mutated AML cases. Gilteritinib and sorafenib also exhibit the potential to reduce relapse rates post-transplant. Isocitrate dehydrogenase inhibitors, including ivosidenib and enasidenib, present novel options for postchemotherapy and posttransplantation maintenance...The approval of oral azacitidine represents a significant advancement, emphasizing the need for further investigation into personalized maintenance approaches. In conclusion, the evolving landscape of maintenance therapy and integrating targeted therapies in AML offers promising avenues for improving patient outcomes.

The CD33-targeting antibody-drug conjugate, gemtuzumab ozogamicin (GO), is commonly added to intensive chemotherapy (IC) in CBF-AML...Induction treatment regimens were categorized as IC alone, IC with GO, or IC with KIT inhibitor (dasatinib or midostaurin)...Patients treated with IC with KIT inhibitor experienced a significantly improved 3-year EFS of 85% compared to those with IC with or without GO (p = 0.04). We find in our study that there is no survival benefit in patients treated with IC with the addition of GO; improved EFS was seen in patients with CBF-AML treated with IC plus KIT inhibitors, consistent with outcomes noted in prospective studies utilizing this approach.

Contemporary Management of Acute Myeloid Leukemia: A Review. (PubMed, JAMA Oncol)
Since then, the understanding of the molecular pathogenesis of AML has expanded, allowing the identification of additional potential targets for drug therapy, treatment incorporation of molecularly targeted therapies (midostaurin, gilteritinib, and quizartinib targeting FLT3 variants; ivosidenib and olutasidenib targeting IDH1 variants, and enasidenib targeting IDH2), and identification of rational combination regimens. The approval of hypomethylating agents combined with venetoclax has revolutionized the therapy of AML in older adults, extending survival over monotherapy. Additionally, patients are now referred for hematopoietic cell transplant on a more rational basis. In the era of genomic medicine, AML treatment is customized to the patient's comorbidities and AML genomic profile.

Sorafenib maintenance in FLT3-ITD mutated AML after allogeneic HCT: a real-world, single-center experience. (PubMed, Front Oncol)
Despite allogeneic hematopoietic stem cell transplant (allo-HCT) and the development of novel FLT3 inhibitors in both induction (midostaurin) and in the relapsed/refractory setting (gilteritinib), FLT3-ITD mutated leukemia (FLT3-ITD+ AML) still represents a challenge for modern hematology. No major long-term toxicity was reported at the last follow-up. Our real-world experience supports the use of sorafenib as a feasible and effective therapeutic option in post-HCT maintenance for FLT3-ITD+ AML.

In addition, time to maximum plasma concentration (Tmax) in these FLT3 inhibitors ranged from 0.7-12.0 hours, but the elimination half-life (T1/2) range was highly variable, from 6.8 to 151.8 h. FLT3 inhibitors monotherapy has shown significant anti-tumor effect in clinic, and the effectiveness may be further improved through combination medication.

Specifically, it explores the historical context of FLT3 inhibitors (FLT3Is) and their impact on treatment outcomes, emphasizing the pivotal role of midostaurin, as well as gilteritinib and quizartinib, and providing detailed insights into ongoing trials exploring the safety and efficacy of novel triplet combinations involving FLT3Is in different AML settings.

Emerging DNA Methylome Targets in FLT3-ITD-Positive Acute Myeloid Leukemia: Combination Therapy with Clinically Approved FLT3 Inhibitors. (PubMed, Curr Treat Options Oncol)
Hence, FLT3 is considered an attractive druggable target; selective small FLT3 inhibitors (FLT3Is), such as midostaurin and quizartinib, have been clinically approved. Therefore, understanding the role of different epigenetic alterations in FLT3-ITD AML pathogenesis and how they modulate FLT3I's activity is important to rationalize combinational treatment approaches including FLT3Is and modulators of methylation regulators or pathways. Data from ongoing pre-clinical and clinical studies will further precisely define the potential use of epigenetic therapy together with FLT3Is especially after characterized patients' mutational status in terms of FLT3 and DNA methlome regulators.

Gemtuzumab ozogamicin plus midostaurin in combination with standard '7 + 3' induction therapy in newly diagnosed AML: Results from the SAL-MODULE phase I study. (PubMed, Br J Haematol)
Three dose levels of midostaurin and one to three sequential doses of 3 mg/m2 GO in combination with '7 + 3' induction were evaluated. Based on safety findings in 12 patients, our results show that 3 mg/m2 GO on Days 1 + 4 and 100 mg midostaurin on Days 8-21 can be safely combined with IC in newly diagnosed AML.

Day-21 bone marrow findings incorrectly designate residual leukaemia in FLT3-mutated acute myeloid leukaemia treated with intensive induction plus midostaurin: a morphology-focused study. (PubMed, Pathology)
In summary, based on morphology alone, D21-BM assessment following 7+3 intensive induction plus midostaurin for FLT3-AML incorrectly designates RL in some patients; thus correlating with associated flow and molecular results is essential before concluding RL following first induction. Where remission status is unclear, repeat D28-BMs should be performed.
