A Phase 1b/2 Study of PCM-075 (Onvansertib) in Combination With Either Low-Dose Cytarabine or Decitabine in Subjects With Acute Myeloid Leukemia (AML)

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.


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)

6. Serum creatinine ≥2.0 mg/dL

7. New York Heart Association Class III or IV heart disease, active ischemia or any other
uncontrolled cardiac condition, or hypertensive or metabolic condition

8. Myocardial infarction in the previous 12 weeks (from the start of treatment)

9. Resting left ventricular ejection fraction <50% at the time of screening

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

12. Presence of risk factors for torsade de pointes, including family history of Long QT
Syndrome or uncorrected hypokalemia

13. Active and uncontrolled disease (other than AML) or infection as judged by the
treating physician

14. Treatment with systemic therapy for the primary disease within 14 days (except for
hydroxyurea or isolated doses of cytarabine or decitabine for white blood cell
control)

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
