Inclusion Criteria:
- Written informed consent and HIPAA authorization for release of personal health
information. NOTE: HIPAA authorization may be included in the informed consent or
obtained separately.
- Male or female patients 18 years or older at the time of consent.
- Patients must have a diagnosis of primary or secondary AML with relapsed or refractory
disease (WHO update 2016, [34]) other than acute promyelocytic leukemia, or complex
karyotype or monosomy 7 (or containing monosomy 7) for whom no standard therapies are
anticipated to result in a durable remission according to the clinical judgment of the
treating physician, or in a patient who refuses standard therapies.
- Must have submitted for Next Generation Sequencing (NGS) testing by: 1) (preferred)
having submitted a tumor sample for commercial myeloid NGS from Foundation One, Mayo,
Tempus, Quest, ARUP or an institutional CLIA-certified laboratory and/or 2) obtaining
a bone marrow aspirate during screening for submission to Foundation One, Mayo,
Tempus, Quest, ARUP or an institutional CLIA-certified laboratory and ordered as
standard of care. If bone marrow aspiration has failed, a peripheral blood sample with
circulating blasts may be substituted. Screening reports on tumor cytogenetics and/or
mutation assays (eg, FLT-3, and NGS) performed as part of the standard of care will be
recorded in the study database or obtained at the time of screening if not previously
available.
- Patient's disease must be characterized for the presence/absence of Flt3ITD/TKD
mutation from an FDA-approved vendor (ex. LabPMM).
- In addition, patients for the phase 2 portion of the study must meet the following:
- Patients, if relapsed/ refractory, must have exposure to no more than 2 prior
chemotherapy regimens. Re-induction with the same regimen or stem cell transplant
will not be considered a separate regimen.
- Patients must not have prior exposure to any investigational Flt3 inhibitors

contraception at the same time, from the time of signing the informed consent
through 180 days after the last dose of study drug, or
- Agree to practice true abstinence, when is in line with the preferred and usual
lifestyle of the subject. Periodic abstinence [eg, calendar, ovulation,
symptothermal, postovulation methods], withdrawal, spermicides only, and
lactational amenorrhea are not acceptable methods of contraception. Female and
male condoms should not be used together.)
- Agree not to donate eggs (ova) during the course of this study or 180 days after
receiving their last dose of study drug.

- Agree to practice effective barrier contraception during the entire study
treatment period and through 180 days after the last dose of study drug, or
- Agree to practice true abstinence, when this is in line with the preferred and
usual lifestyle of the subject. (Periodic abstinence [eg, calendar, ovulation,
symptothermal, postovulation methods for the female partner] and withdrawal are
not acceptable methods of contraception. Female and male condoms should not be
used together.)
- Agree not to donate sperm during the course of this study or within 180 days
after receiving their last dose of study drug.

procedure not part of standard medical care, with the understanding that consent may
be withdrawn by the patient at any time without prejudice to future medical care
- In the absence of rapid progressive disease, the interval from prior systemic
anticancer treatment to time of TAK-659/Ixazomib administration should be at least 2
weeks for cytotoxic agents (other than hydroxyurea), or at least 5 half-lives for
noncytotoxic agents, and patients have to have recovered from acute toxicities of
these therapies. Patients who are on hydroxyurea may be included in the study and may
continue on hydroxyurea for the first 21 days while participating in this study. NOTE:
For patients with a white blood cell count >50,000/uL, hydroxyurea may be used to
control the level of circulating leukemic blast cell counts prior to study entry, and,
if needed, concomitantly while on TAK-659 treatment during the first 21 days of the
study.
- Suitable venous access for the study-required blood sampling, and transfusion support.
- Demonstrate adequate organ function as defined in the protocol; all screening labs to
be obtained within 28 days prior to registration.
Exclusion Criteria:
- Clinically active central nervous system leukemia.
- Female patients who are lactating and breastfeeding (NOTE: breast milk cannot be
stored for future use while the mother is being treated on study)
- Female patients who have a positive serum pregnancy test during the screening period
or a positive urine pregnancy test on Day 1 before first dose of study drug.
- Any serious medical or psychiatric illness, including drug or alcohol abuse, that
could, in the investigator's opinion, potentially jeopardize the safety of the patient
or interfere with the objectives of the study.
- Prior treatment with investigational agents ≤ 21 days or ≤ 5 half-lives (whichever is
shorter) before the first dose of study treatment. A minimum of 10 days should elapse
from prior investigational therapy to initiating protocol therapy.
- Persistent clinically significant toxicity from prior chemotherapy that is Grade 2 or
higher by the NCI CTCAE (v5).
- Receipt of HSCT within 60 days of the first dose of TAK-659/Ixazomib; clinically

antiviral therapy or other serious infection within 10 days before the first dose of
study drug.
- Major surgery within 14 days before the first dose of study drug and have not
recovered fully from any complications from surgery.
- Radiotherapy less than 2 weeks before the first dose of study treatment or have not
recovered from acute toxic effects from radiotherapy.
- Known human immunodeficiency virus (HIV) positive.
- Known hepatitis B surface antigen positive, or known or suspected active hepatitis C
infection (testing not required).
- Any of the following cardiovascular conditions:
- Acute myocardial infarction within 6 months before starting study drug.

arrhythmias, angina, pulmonary hypertension, or electrocardiographic evidence of
acute ischemia or active conduction system abnormalities.
- Fridericia corrected QT interval (QTcF) >450 milliseconds (msec) (men) or >475
msec (women) on a 12-lead ECG during the Screening period.
- Abnormalities on 12-lead ECG including, but not limited to, changes in rhythm and
intervals that, in the opinion of the treating physician, are considered to be
clinically significant.
- Known gastrointestinal (GI) disease or GI procedure that could interfere with the oral
absorption or tolerance to study drugs, including difficulty swallowing tablets,
diarrhea > Grade I despite supportive therapy.
- Use or consumption of any of the following medications, supplements, or
foods/beverages that are inhibitors or inducers of P-gp or strong reversible
inhibitors or inducers of CYP3A within the indicated timeframes below. Note that use
or consumption of these substances is not permitted during the study.
- Inhibitors of P-gp and/or strong reversible inhibitors of CYP3A within 5 times
the inhibitor half-life (if a reasonable half-life estimate is known), or within
7 days (if a reasonable half-life estimate is unknown), before the first dose of
study drug. In general, the use of these agents is not permitted during the study
except in cases where an AE must be managed. See SPM for a nonexhaustive list of
strong CYP3A reversible inhibitors and/ or Pgp inhibitors based on the FDA Draft
DDI Guidance.
- Strong CYP3A mechanism-based inhibitors or strong CYP3A inducers and/or P-gp
inducers within 7 days, or within 5 times the inhibitor or inducer half-life
(whichever is longer), before the first dose of study drug. However, if a patient
has a strong indication for fungal prophylaxis, then the moderate CYP3A
inhibitors fluconazole or isovuconazole (mold-active) is recommended for
prophylaxis, and the TAK-659 dose should be reduced to 60mg, along with increased
scrutiny for toxicity. Similarly, if the patient develops a fungal infection
during a productive intervention with TAK-659/Ixazomib combination, isovuconazole
(mold-active) should be used, along with increased scrutiny for toxicity. In
general, the use of these agents is not recommended during the study except in
cases where such an AE must be managed, and the intermittent schedule of
TAK-659/Ixazomib combination will not prevent profound neutropenia. See SPM for a
non-exhaustive list of strong CYP3A mechanism-based inhibitors or strong CYP3A
inducers and/or P-gp inducers based on the FDA Draft DDI Guidance.
- Grapefruit-containing food or beverages within 5 days before the first dose of
study drug.
- Lack of suitable venous access for the study-required blood sampling.
- Diagnosed or treated for another malignancy within 2 years before study enrollment or
previously diagnosed with another malignancy and have any evidence of residual
disease. Patients with nonmelanoma skin cancer or carcinoma in situ of any type are
not excluded if they have undergone complete resection.
- Patient has Grade 3 peripheral neuropathy, or Grade 2 with pain on clinical
examination during the screening period.
- Known allergy to any of the study medications, their analogues, or excipients in the
various formulations of any agent.
