Revumenib in Combination With Azacitidine + Venetoclax in Patients NPM1-mutated or KMT2A-rearranged AML

Inclusion Criteria: In order to be eligible to participate in this study, a patient must meet all of the following criteria: 1. Patient with newly diagnosed NPM1-mutated AML, consistent with NPM1c, according to the 2022 International Consensus Classification (i.e. ≥ 10% blasts). OR Patient with newly diagnosed KMT2A-rearranged AML according to the 2022 International Consensus Classification (i.e. ≥ 10% blasts). KMT2A partial tandem duplications or deletions are NOT eligible. Of note: in case both NPM1 and IDH1 are mutated and both EVOLVE-1 (HO173) and EVOLVE-2 (HO177) are open for inclusion at your site, then patients can only be included in the EVOLVE-1 trial (HO173) 2. Central confirmation of NPM1 mutation or KMT2A rearrangement in one of the dedicated central genetic laboratories. 3. Age ≥ 18 years, no upper age limit. 4. Patient is ineligible for intensive induction chemotherapy by meeting at least 1 of the following criteria: * ≥ 75 years of age: ineligible for intensive chemotherapy per physician's discretion (with an ECOG performance status 0-2) . * 18-74 years: patient is not eligible for standard chemotherapy because any of the following co-morbidities: * ECOG performance status 2 or 3 . * Cardiac history of chronic heart failure requiring treatment; or with an ejection fraction ≤50%; or chronic stable angina. * DLCO ≤ 65% or FEV1 ≤ 65%. * Creatinine clearance ≥ 30 mL/min to \<45 ml/min calculated by the Cockcroft Gault formula. * Moderate hepatic impairment with total bilirubin \> 1.5 to \< 3.0 x upper limit of normal (ULN). * Any other comorbidity that the local physician assesses to be incompatible with intensive chemotherapy must be reviewed and approved by the Sponsor's (co-) Principal Investigator (written approval must be sent to HO177@erasmusmc.nl before study enrolment). 5. Patient must have a projected life expectancy of at least 12 weeks (as assessed by the treating physician). 6. Patient must have a white cell blood (WBC) count of \< 25 x 109/L. Hydroxyurea can be used prior to study enrolment to reduce the WBC count to meet this criterion. 7. Adequate renal function as evidenced by serum creatinine ≤ 2.0 × upper limit of norm (ULN) or creatinine clearance \>30 mL/min based on the Cockcroft-Gault glomerular filtration rate (GFR). 8. Adequate hepatic function as evidenced by: * Serum total bilirubin ≤ 3.0 × ULN unless considered due to Gilbert's disease, or leukemic involvement following written approval by the sponsor (Co-)Principal Investigator (copy in HO177@erasmusmc.nl). * Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) ≤ 3.0 × ULN, unless considered due to leukemic involvement following written approval by the sponsor (Co-)Principal Investigator (copy in HO177@erasmusmc.nl). 9. Female patient must: * be of nonchildbearing potential: o postmenopausal (defined as at least 1 year without any menses). o documented surgically sterile (e.g. documented hysterectomy, bilateral oophorectomy, bilateral salpingectomy or congenital sterile) or status post hysterectomy (at least 1 month prior to screening). * or, if of childbearing potential (not surgically sterile and not postmenopausal) agree to avoid pregnancy during the study and for 6 months after the final study drug administration. * and have a negative urine or serum pregnancy test at screening. * and, if heterosexually active, agree to consistently apply one highly effective\* method of birth control in combination to a barrier method for the duration of the study and for 6 months after the final study drug administration. \*Highly effective forms of birth control include \- Consistent and correct usage of established hormonal contraceptives that inhibit ovulation for at least 1 month prior to taking study drug. (hormonal contraception is only a highly effective method of birth control, if a combined \[estrogen and progestogen containing\] hormonal contraception or a progestogen-only hormonal contraception - both associated with inhibition of ovulation - is used. \- Established intrauterine device (IUD) or intrauterine system (IUS) \- Bilateral tubal occlusion \- Vasectomy - a vasectomy is highly effective contraception method provided the absence of sperm has been confirmed. If not, an additional highly effective method of contraception should be used. \- Male is sterile due to a bilateral orchiectomy. * Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual activity during the entire period of risk associated with the study drug. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the patient. List is not all inclusive. Prior to enrolment, the investigator is responsible for confirming patient will utilize highly effective forms of birth control in combination with a barrier method according to locally accepted standards during the protocol defined period. * agree not to breastfeed starting at screening and throughout the study period. * agree not to donate ova starting at screening and throughout the study period, and for 6 months after the final study drug administration. 10. Men must use a latex condom during any sexual contact with women of childbearing potential (WOCBP), even if they have undergone a successful vasectomy and must agree to avoid to father a child (while on therapy and for 6 months after the final study drug administration). In addition, their female partners of childbearing potential must use a highly effective method of birth control. 11. Male patient must not donate sperm starting at screening and throughout the study period and for 6 months after the final study drug administration. 12. Able to understand and willing to sign an informed consent form (ICF). 13.
