Open to people ages 18 years and up

  1. Patients aged ≥18 years at time of screening
  2. Written informed consent by the patient (or legal representative) prior to admission to this study. In addition any locally required authorization (Health Insurance Portability and Accountability Act in the USA [HIPAA], obtained from the patient prior to performing any protocol-related procedures, including screening evaluations.
  3. Adequate renal and hepatic function defined as:
  4. Total bilirubin within 1.5 x ULN, except those with Gilberts syndrome for whom this must be <3 x ULN
  5. AST(SGOT) and ALT(SGPT) <2.5 x ULN
  6. Calculated Creatinine clearance>/= 45ml/min
  7. Serum Albumin >2.5g/dL For any patient laboratory values outside the ranges outlined above that are considered due to the patient's underlying disease (AML, MDS or ALL), the patient may be enrolled into the study following consultation between the Investigator and the Sponsor's Medical Officer if the patient is likely to benefit from receiving ONO-7475 (based on the Investigator's assessment)
  8. Eastern Cooperative Oncology Group (ECOG) performance status 0-2 as assessed during the screening period and then again anytime during the 2-day period immediately preceding the start of ONO-7475 dosing.
  9. Life expectancy of at least 3 months
  10. Sexually active female patients of childbearing potential and sexually active male patients must agree to use an effective method of birth control (e.g., barrier methods with spermicides, oral or parenteral contraceptives and/or intrauterine devices) during the entire duration of the study and for 4 months after final administration of study drug. Note that sterility in female patients must be confirmed in the patients' medical records and be defined as any of the following: surgical hysterectomy with bilateral oophorectomy, bilateral tubular ligation, natural menopause with last menses >1 year ago; radiation induced oophorectomy with last menses >1 year ago; chemotherapy induced menopause with last menses >1 year ago.
  11. Male patients must use a condom from the time of the first administration of ONO-7475 until 4 months following administration of the last dose.
  12. Diagnosis of AML or MDS according to WHO criteria 2016.
  13. Either criterion is met:
  14. Relapsed or refractory AML patients with at least 5% blasts by bone marrow biopsy or aspirate, or at least 1% blasts in peripheral blood, not likely to benefit from standard salvage chemotherapy.
  15. Relapsed or refractory MDS patients who are either not eligible for (or unlikely to benefit from) other forms of therapy including hematopoietic stem cell transplantation, according to the treating physician/investigator
  16. . All patients must have received at least one previous line or therapy.

  3. Clinically significant liver disease, including active viral or other hepatitis, current alcohol abuse, or severe cirrhosis
  4. HIV/active Hepatitis B or C infection
  5. Retinal disease (e.g. retinitis pigmentosa including Mertk mutations), retinal hemorrhage or any disorder which may inhibit follow up for retinal toxicity
  6. Serious intercurrent medical or psychiatric illness that will prevent participation or compliance with study procedures, including serious active infection
  7. Acute promyelocytic leukemia (FAB M3 classification)
  8. Patients not recovered to Grade 1 or stabilized from the effects (excluding alopecia) of any prior therapy for their malignancies
  9. Concurrent treatment with other investigational drugs.

  13. . Prior AML, MDS or ALL therapy (non-experimental) within 14 days or five half-lives whichever is longer, prior to the first dose of ONO-7475 (except those permitted in the protocol) and no residual toxicity from the prior therapy hindering of the ONO-7475 dosing.
  14. . Prior radiotherapy within 21 days of screening, with the exception of localized palliative radiotherapy.
  15. . Patients undergoing current treatments for other cancers
  16. . Pregnant or lactating women
