Revuforj (revumenib)

This review highlights the evidence defining its poor prognosis, which is primarily driven by profound chemoresistance to conventional therapies, including glucocorticoids. Finally, we discuss the rapidly evolving therapeutic landscape, detailing the limitations of standard intensive chemotherapy and the immense promise of novel targeted strategies, such as Menin inhibitors (e.g., Revumenib), DOT1L inhibitors, and immunotherapies (e.g., CAR-T cells, Blinatumomab), which hold the potential to revolutionize outcomes for this high-risk leukemia subtype.

Menin inhibitor approval/use is expanding into other HOX-driven subtypes (e.g. NPM1, NUP98r), as frontline option and in combination settings. Monitoring for differentiation syndrome, QT interval prolongation, recognizing pseudo-progression, and supportive care needs remains essential to maximize patient benefit.

The 84 patients (63% KMT2Ar, n=53; 23% NPM1c, n=19) who received MENINi were heavily pre-treated: 86% (n=72) had prior intensive chemotherapy (IC), 77% venetoclax (VEN, n=67), and 38% (n=32) allogeneic stem cell transplantation...Of the 60% (n=50) that were treated, common regimens were hypomethylating agent (HMA)/VEN (26%, n=13), clinical trial (26%, n=13), and gilteritinib-based therapy (18%, n=9)...All CR/CRi occurred with HMA/VEN (n=2, 15%), IC+VEN (n=4, 67%), or MENINi switching (bleximenib to revumenib, n=1, 50%)...Outcomes after MENINi failure are poor, but responses occur with VEN-based regimens or MENINi switching. FLT3-ITD, WT1, and MEN1 mutations are associated with resistance.

Next-generation agents (ziftomenib, bleximenib, enzomenib, BMF-219) have displayed similar composite complete remission rates (20-35%) and overall response rates (45-65%) in heavily pretreated KMT2Ar and NPM1m acute myeloid leukemia (AML) with measurable residual disease (MRD) negativity and prolonged overall survival (5-7 months)...Acquired mutations in the menin gene described in 39% of post-revumenib relapses have not been identified following other inhibitors (ziftomenib, bleximenib), prompting new questions about resistance mechanisms. These promising results swiftly led to the launch of multiple trials of menin inhibitors combined with intensive (cytarabine and anthracycline) and nonintensive (venetoclax and hypomethylating) chemotherapy backbones...Ongoing/pending phase 3 trials will clarify whether menin blockade should be incorporated into frontline and maintenance regimens for all patients with KMT2A rearranged or NPM1 mutant disease. In the current era, menin inhibition remains a key pillar of the success of precision medicine for AML therapy.

Among them, revumenib and ziftomenib have advanced furthest in clinical testing. Ongoing trials are now evaluating menin inhibitors in rational combinations, frontline regimens, and maintenance therapy. Collectively, these advances highlight menin inhibition as a transformative strategy in acute leukemia, reshaping therapy through precision-targeted epigenetic intervention.

Exposing EwS cells to the Menin inhibitor VTP50469 (revumenib) inhibited expression of MYC targets and co-immunoprecipitation studies detected Menin:MYC interactions that were partially disrupted by the drug. Metastatic colonization of disseminated EwS cells in vivo was significantly inhibited in mice fed VTP50469 chow. Together these findings implicate Menin as a mediator of EwS metastasis and suggest that Menin inhibitors warrant investigation as novel therapeutics for patients with high-risk disease.

Using a degron-tagged ZMYND11 mouse model to enable the rapid degradation of ZMYND11 in primary cortical neurons, we show that gene expression changes induced by ZMYND11 loss are attenuated by treatment with the KMT2A inhibitor revumenib, a drug which has recently been approved for the treatment of KMT2A-rearranged leukemia. Our findings shed light on the convergence of chromatin mechanisms regulating neuronal gene expression and raise the possibility that modulation of KMT2A activity may be a useful therapeutic avenue for ZRSID.
