For FLT3-Mutated Relapsed/Refractory Acute Myeloid Leukemia, Venetoclax Plus Gilteritinib

For FLT3-Mutated Relapsed/Refractory Acute Myeloid Leukemia, Venetoclax Plus Gilteritinib

One of the most frequently altered genes in acute myeloid leukemia is FMS-like tyrosine kinase 3 internal tandem duplication, particularly in patients with normal cytogenetics. As indicators for high-risk AML, the FLT3-ITD and FLT3-TKD mutations are linked to both treatment resistance and a high probability of relapse. To treat AML with an Flt3 mutation. Gilteritinib is a dual FLT3/AXL small molecule inhibitor. Compared to salvage chemotherapy for refractory AML, the ADMIRAL trial showed that gilteritinib is associated with more prolonged overall survival and a greater response rate. Venclyxto 100 mg price may differ from dosages. These findings from the ADMIRAL study could change how we approach treatment and make gilteritinib the new gold standard for R/R FLT3-mutated AML. Several clinical trials are currently being conducted to assess the interaction of gilteritinib with different medications. With a fast track and priority review status, this medication was approved after being developed as an orphan drug.


The FMS-related tyrosine kinase 3 inhibitor gilteritinib is the standard treatment for acute myeloid leukemia that has relapsed or become resistant to treatment and has FLT3 mutations. Still, it rarely lowers the FLT3mut burden or results in sustained efficacy. In preclinical models of FLT3mut AML, gilteritinib works in concert with the BCL-2 inhibitor venetoclax.


Patients with FLT3 wild-type and FLT3 mutation or FLT3 mutation relapsed/refractory AML were included in this phase Ib open-label, dose-escalation/dose-expansion research. Patients were given 80 mg or 120 mg of gilteritinib, and the Venclytax price may differ from online store to pharmacy. Safety, determining the phase II dose that should be used and measuring the modified composite complete response rate using ADMIRAL phase III-defined response criteria (complete response [CR] + CR with incomplete blood count recovery + CR with incomplete platelet recovery + morphologic leukemia-free state) were the main goals.

Mechanism of action:

Both the FLT3 receptor’s internal tandem duplication and tyrosine kinase domain mutations can be effectively inhibited by the drug gilteritinib. In the same vein, gilteritinib blocks the tyrosine kinases AXL and ALK. Cancer cell growths are regulated by the molecules FLT3 and AXL. The phosphorylation of FLT3 and its downstream targets, including STAT5, ERK, and AKT, can be inhibited thanks to gilteritinib’s activity. According to studies, acute myeloid leukemia patients present with a mutationally activated isoform in about 30% of cases. Additionally, the mutation ITD is linked to poor patient outcomes, the mutation TKD results in a resistance mechanism to FLT3 tyrosine kinase inhibitors, and the AXL tyrosine kinase tends to result in a resistance mechanism to chemotherapy.

Final thoughts:

The use of gilteritinib for R/R AML with FLT3 mutations has been authorized. According to the ADMIRAL research, gilteritinib for R/R AML is associated with a higher response rate and more prolonged overall survival than salvage chemotherapy. Hayat Alhikmah is the best choice for the quality of medicine supply, and venclyxto price will be more reasonable. These findings from the ADMIRAL study could change how therapy is approached and make gilteritinib the new gold standard treatment for R/R FLT3-mutated AML.
