Details
- Phase:
- Prospective randomized Phase III study
- Monitoring Type:
- Study Specific
- Objectives:
Primary study objective
- To assess if treatment with revumenib, in combination with azacitidine and venetoclax, prolongs overall survival (OS) in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
Key secondary study objectives:
- To assess if treatment with revumenib, in combination with azacitidine and venetoclax, prolongs event-free survival (EFS) in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
- To assess if treatment with revumenib, in combination with azacitidine and venetoclax, increases the combined rate of complete remission (CR) and CR with partial hematologic recovery (CRh) (CR/CRh) in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
- To assess if treatment with revumenib, in combination with azacitidine and venetoclax, increases the rate of CR in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
Other secondary study objectives:
- To assess if treatment with revumenib, in combination with azacitidine and venetoclax, increases the rate of CRh in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
- To assess if treatment with revumenib, in combination with azacitidine and venetoclax, increases the combined rate of CR and CR with incomplete hematologic recovery (CRi) (CR/CRi) in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
- To assess if treatment with revumenib, in combination with azacitidine and venetoclax, increases the rate of CR, CR/CRh and CR/CRi without measurable residual disease (CRMRD-, CR/CRhMRD- and CR/CRiMRD-) assessed by quantitative PCR in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
- To assess if treatment with revumenib, in combination with azacitidine and venetoclax, shortens the time to response (CR, CR/CRh and CR/CRi) in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
- To assess if treatment with revumenib, in combination with azacitidine and venetoclax, prolongs duration of response (CR, CR/CRh and CR/CRi; DoR) in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
Explorative objectives
- To evaluate OS, EFS, DoR, and rates of CR, CR/CRh and CR/CRi by prognostic variables, including clinical variables (e.g., age at randomization, sex, ECOG performance status, white blood cell count), 2022 European LeukemiaNet (ELN) risk groups, geographical region and by specific AML genotypes in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
- To assess if treatment with revumenib, in combination with azacitidine and venetoclax, increases the rate of CR, CR/CRh, and CR/CRi without measurable residual disease (CRMRD-, CR/CRhMRD- and CR/CRiMRD-) assessed by multiparameter flowcytometry in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
- To evaluate resistance mechanisms after combined treatment with azacitidine/venetoclax/revumenib (e.g. MEN1 mutations, RAS mutations, FLT3 mutations, TP53 mutations).
- To evaluate the impact of revumenib, in combination with azacitidine and venetoclax, on quality of life (QoL), using EORTC QLQ-C30 and EQ-5D-5 in adult patients with newly diagnosed NPM1-mutated AML ineligible for intensive chemotherapy.
- To evaluate OS, EFS, rates of CR, CR/CRh, CR/CRi, CRMRD-, CR/CRhMRD-, CR/CRiMRD, time to response and DoR in adult patients with newly diagnosed KMT2A-rearranged AML ineligible for intensive chemotherapy.
- To characterize PK of revumenib and relevant metabolites in combination with azacitidine and venetoclax.
- To evaluate revumenib pharmacodynamic relationship with safety, efficacy and correlative biomarkers, which may include immunophenotyping of circulating peripheral blood mononuclear cells (PBMC) and/or bone marrow, gene expression, mutational analysis, and minimal residual disease (MRD).
Eligibility

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)

- Age ≥ 18 years, no upper age limit.
- 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) (Appendix C).
- 18-74 years: patient is not eligible for standard chemotherapy because any of the following co-morbidities:
- ECOG performance status 2 or 3 (Appendix C).
- Cardiac history of chronic heart failure requiring treatment; or with an ejection fraction ≤50%; or chronic stable angina.

- Patient must have a projected life expectancy of at least 12 weeks (as assessed by the treating physician).
- 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.
- 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).
- 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).
- Female patient must:
- be of nonchildbearing potential:

- 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.

- 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.

Registration Details
Patients who are possibly eligible for this trial should first be screened to determine the NPM1 mutation or KMT2a rearrangement status. This can only be done after the patient has provided a written informed consent for the screening. Screening is done through a separate screening database. There are two screening databases for this trial, one managed by HOVON and one managed by AMLSG. Each group/institute that is participating in this trial is assigned one of the two screening databases.
Eligible patients should be registered before start of treatment. Patients need to be registered at HOVON by one of the following options:
- By ALEA; Use goto eCRF button > select the [Patient tab] and click the [Add new patient] button. Complete all items and click the [Submit] button
- By emailing the completed registration/randomization CRF to HO177@erasmusmc.nl (possible on Monday through Friday, from 09:00 to 17:00 CET)
