Brief Summary:
The purpose of the phase 1b/2 study is to determine whether Onvansertib given orally daily for 5 consecutive days every 28 days is safe and tolerable in adult patients who have relapsed/refractory Acute Myeloid Leukemia, or are ineligible for intensive induction therapy, and to determine the maximum tolerated dose or recommended phase 2 dose of Onvansertib in combination with decitabine or and Onvansertib in combination with low-dose cytarabine. In the phase 2 portion of the study, one regimen (either Onvansertib in combination with decitabine or Onvansertib in combination with low-dose cytarabine) will be studied to provide further data on the safety profile of the combination and to preliminarily assess the activity of the chosen combination in patients with untreated AML who are not candidates for aggressive induction therapy, or who have received one prior treatment for their AML.

  2. Phase 2: Rate of partial response (PR) [ Time Frame: Baseline up to 30 days after last dose of study drug (up to 27 months) ]

Criteria

Inclusion Criteria:

  1. Disease Status and Prior Therapy:

    1. Histologically confirmed AML with >20% blasts
    2. Phase 1b: Participants with AML who are refractory to or have relapsed after initial treatment for their disease, with no more than three prior lines of therapy. Participants who have received prior treatment with cytarabine or decitabine are not excluded.
    3. Phase 2:

    i. Participants with AML who are refractory to, or have relapsed after, initial treatment for their disease, with no more than one prior line of therapy, and are judged not to be candidates for re-induction therapy that includes hematopoietic cell transplantation. Participants who have received prior cytarabine or decitabine are not excluded.

    OR

    ii. Participants with newly diagnosed, untreated AML ineligible for, or who have refused, standard intensive induction therapy

  2. Age ≥18 years
  3. ECOG performance status ≤2
  4. Participants must be willing and able to review, understand, and provide written consent before starting any study-specific procedures or therapy.
  5. All men and women must agree to practice effective contraception during the entire study period and after discontinuing study drug, unless documentation of infertility exists

    1. Sexually active, fertile women must use two effective forms of contraception (abstinence, intrauterine device, oral contraceptive, or double barrier device) from the time of informed consent and until at least 6 months after discontinuing study drug
    2. Sexually active men and their sexual partners must use effective contraceptive methods from the time of participant informed consent and until at least 3 months after discontinuing study drug

Exclusion Criteria:

  1. Treatment-related AML or acute promyelocytic leukemia (APL)
  2. Active malignancies within 12 months with the exception of those with a negligible risk of metastasis or death
  3. Clinical evidence of active central nervous system leukemia at the time of screening
  4. Alanine aminotransferase and/or aspartate aminotransferase ≥2.5 x upper limit of normal (ULN)
  5. Total bilirubin > 2.0 mg/dL (or > 3.0 mg/dL in participants with documented Gilbert syndrome)

  10. QT (Interval from the beginning of the QRS complex to the end of the T wave on an electrocardiogram) interval with Fridericia's correction [QTcF] >450 milliseconds. The QTcF should be calculated as the arithmetic mean of the QTcF on triplicate ECGs. In the case of potentially correctible causes of QT prolongation (e.g., medications, hypokalemia), the triplicate ECG may be repeated once during screening and that result may be used to determine eligibility.
  11. Planned concomitant use of medications known to prolong the QT/QTc interval

  15. Grade 2 or greater toxicities from prior therapy, except for Grade 2 toxicities that are not expected to resolve and that in the judgment of the Investigator do not pose a significant safety risk to subject participation.
  16. Participants with any other medical condition, including mental illness or substance abuse, deemed by the Investigator to be likely to interfere with the participant's ability to sign the informed consent form or his/her ability to cooperate and participate in the study, or to interfere with the interpretation of the results
