Comparing trials like Sequoia (zanubrutinib) and Amplify (acalabrutinib-venetoclax) is invalid without adjusting for baseline population differences. Amplify's inclusion of an FCR chemo-arm meant its patients were inherently more fit, necessitating statistical matching for a fair comparison.

Despite impressive data supporting HMA/Venetoclax, its application in younger, fit patients must be cautious. The pivotal VIALE-A trial excluded key subgroups like FLT3, core binding factor, and certain NPM1 patients, for whom intensive chemotherapy remains the standard.

The FLAG-IDA plus venetoclax regimen achieves very high MRD-negative remission rates. However, its similar efficacy in both frontline and first salvage settings suggests it might be more strategically deployed as a salvage therapy, avoiding its high toxicity in all patients upfront.

To combat the significant myelosuppression from the standard 28-day venetoclax cycle in AML, many clinicians are adopting a strategy of performing a bone marrow biopsy around day 21 and pausing the drug if blast clearance is achieved to allow for hematologic recovery.

Similar to FLT3 inhibitors like midostaurin, which failed in the relapsed setting but succeeded upfront, menin inhibitors are expected to show dramatically better efficacy when combined with standard induction or HMA/Venetoclax in newly diagnosed patients.

While quizartinib's benefit is less pronounced in AML patients over 60, a specific genomic signature—the co-occurrence of FLT3-ITD, NPM1, and DNMT3A mutations—identifies a subset of older patients who derive a significant survival benefit, challenging age-based treatment decisions.

When evaluating data for relapsed/refractory AML, clinicians must look beyond headline response rates. The number of prior therapies a patient has received dramatically impacts outcomes. A trial with a median of one prior treatment will have vastly different results than one with five.

While adding a menin inhibitor to the azacitidine/venetoclax doublet for older/unfit AML patients increases response rates, it leaves little reserve for marrow function. This can lead to increased risk of early, fatal complications like infection or bleeding, requiring careful dose management.

A key advantage of the FLT3 inhibitor quizartinib over midostaurin is its demonstrated survival benefit in FLT3-ITD positive AML patients who do not proceed to an allogeneic transplant in their first remission. This makes it a more robust upfront option for a broader patient group.
