Sexually active male participants are asked to advise their female partners of childbearing potential to also use highly effective contraception for the same time period.
- Agree not to donate blood, eggs (ova) or sperm, during study participation and until 28 weeks (approximately 6.5 months) after the last dose of study drug (Section 10.4).
- Investigator considers the participant to be suitable for participation in the clinical study by assessing that they: - understand the requirements of the clinical study and can give informed consent - can comply with study medication dosing requirements and all study-related procedures and evaluations - are not considered to be potentially unreliable and/or not cooperative.
- Has received all Coronavirus disease-19 (COVID-19) vaccinations per relevant national guidelines.
You likely can't join if
- Active central nervous system leukemia
- Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of RVU120 (e.g., active inflammatory bowel disease, ulcerative disease, malabsorption syndrome, short bowel syndrome, uncontrolled nausea, vomiting or diarrhea).
- Ongoing drug-induced pneumonitis
- Concurrent participation in another therapeutic clinical trial
- Taking any medications, herbal supplements, or other substances that are known to be strong inhibitors or moderate/strong inducers or sensitive substrates of CYPXXX, within less than 5 half-lives prior to first dose of study drug (Section 10.9).
- Significant cardiac dysfunction defined as myocardial infarction within 12 months of first dose of study drug, New York Heart Association (NYHA) Class III or IV heart failure, uncontrolled dysrhythmias, poorly controlled angina (Section 10.10), or left ventricular ejection fraction <40% as per echocardiography or multiple gated acquisition (MUGA) scan.

- Has received all Coronavirus disease-19 (COVID-19) vaccinations per relevant national guidelines.
- Age ≥18 years at time of provision of informed consent.
- Diagnosis of AML or MDS as follows: • Cohort 1: AML according to the 2022 World Health Organization (WHO) classification (Arber 2022) in the absence of a mutation in the NPM1 or DNMT3A gene • Cohort 2: AML according to the 2022 WHO classification (Arber 2022) with a mutation in the NPM1 gene regardless of any other co-occurring mutation • Cohort 3: AML according to the 2022 WHO classification (Arber 2022) in the absence of a mutation in the NPM1 gene and with a mutation in the DNMT3A gene • Cohort 4: MDS according to the 2022 WHO classification (Arber 2022) confirmed as high risk with IPSS-R >4.5 following the most recent line of treatment (Section 10.6).
- Relapsed or refractory AML per the ELN 2022 (Döhner 2022) or relapsed or progressing HR-MDS per the International Working Group response criteria in MDS (Zeidan 2023). Participants with AML and <10% bone marrow cellularity may be enrolled where immunophenotyping of the bone marrow demonstrates this is due to underlying disease and not to potential myelotoxicity e.g., where >50% of cells have AML phenotype.
- Failed at least 1 line of therapy and no available alternative therapeutic options likely to produce clinical benefit.
- Eastern Cooperative Oncology Group (ECOG) performance score of 0-2 (Section 10.7).
- No other anti-cancer treatment received for 4 weeks or 5 half-lives, whichever is shorter, prior to first dose of study drug.
- Must have recovered from the toxic effects of previous treatments to at least Grade 1, except for neurotoxicity (which should return at least to Grade 2 or baseline), or alopecia.
- Clinical laboratory parameters as follows: a. peripheral white blood cell (WBC) count, no upper limit during Screening, but must be <30 x 109/L on Day 1 prior to first dose of study drug. b. platelet count >10,000 /μL Note: Platelet infusion permitted c. serum albumin ≥ 25 g/L (2.5 g/dL) d. normal coagulation (elevated international normalized ratio, prothrombin time or activated partial thromboplastin time [APTT] <1.3 x the upper limit of normal [ULN] acceptable) e. aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤3 x ULN f.
