PURPOSE:
Revumenib is an oral inhibitor of menin-KMT2A, a key dependency in acute myeloid leukemia (AML) with
KMT2A
rearrangement (
KMT2Ar
),
NPM1
mutation (
NPM1mt
), or
NUP98
rearrangement (
NUP98r
). Preclinical studies suggest synergy with BCL2 inhibition.
METHODS:In this phase I-II study, we evaluated an all-oral regimen of revumenib, decitabine/cedazuridine, and venetoclax in patients 12 years and older with relapsed or refractory AML. Decitabine/cedazuridine was given on days 1-5, venetoclax on days 1-14, and revumenib twice daily on days 1-28. The primary objectives were to determine the recommended phase II dose (RP2D) and to assess efficacy according to the composite complete remission (CRc) rate.
RESULTS:
Forty-two patients were enrolled (median age, 40 years; range, 12-82) including 40% with
KMT2Ar,
38% with
NPM1mt
, and 21% with
NUP98r.
Patients had a median of two prior lines of therapy; 52% had prior venetoclax. The RP2D of revumenib was 160 mg twice daily with a strong CYP3A4 inhibitor. Grade ≥3 adverse events included febrile neutropenia (36%), lung infection (21%), and thrombocytopenia (21%). Differentiation syndrome occurred in 10% (5% grade 3) and resolved with glucocorticoids. The CRc rate was 71%, and the CR or complete remission with partial hematologic recovery (CR/CRh) rate was 60%, with measurable residual disease negativity by flow cytometry in 80% of these patients. The median duration of CR/CRh for all patients was 10.5 months, not reached in
KMT2Ar
, 10.7 months in
NPM1mt
, and 5.9 months in
NUP98r
. Emergent mutations in the menin-binding site occurred in 13%.
CONCLUSION:This combination was associated with high response rates and durable remissions, with an acceptable safety, in heavily pretreated patients with AML harboring alterations susceptible to menin inhibition.
