| Eligibility |
Inclusion Criteria:
- Phase 1B: Diagnosis of relapsed/refractory AML (excluding acute promyelocytic
leukemia)
- Phase 2A: Diagnosis of relapsed/refractory AML (excluding acute promyelocytic
leukemia) with MAPK pathway mutations e.g. N or KRAS, PTPN11, NF1 etc.
1. Patients aged =18 years old with relapsed/refractory AML with MAPK pathway
mutations e.g. N or KRAS, PTPN11, NF1 etc. are eligible if they are not eligible
for potentially curative therapy such as more effective salvage therapy or
hematopoietic stem cell transplantation or who refuse these options at the time
of enrollment.
2. Patient must be receiving protocol therapy as salvage 1 or 2.
- Phase 1B: Diagnosis of relapsed/refractory AML (excluding acute promyelocytic
leukemia)
- Phase 2A: Diagnosis of relapsed/refractory AML (excluding acute promyelocytic
leukemia) with MAPK pathway mutations e.g. N or KRAS, PTPN11, NF1 etc.
1. Patients aged =18 years old with relapsed/refractory AML with MAPK pathway
mutations e.g. N or KRAS, PTPN11, NF1 etc. are eligible if they are not eligible
for potentially curative therapy such as more effective salvage therapy or
hematopoietic stem cell transplantation or who refuse these options at the time
of enrollment.
2. Patient must be receiving protocol therapy as salvage 1 or 2.
3. Patients aged = 18 years old, with MDS or CMML treated with hypomethylating agent
(HMA) therapies who progress to AML and have no available therapies or are not
candidates for available therapies, will be eligible at the time of progression
to AML.
- Eastern Cooperative Oncology Group (ECOG) Performance Status =2
- Temporary prior measures such as apheresis while eligibility work-up is being
performed are allowed and not counted as a prior salvage
- In the absence of rapidly progressing disease, the interval from prior treatment to
time of initiation of protocol therapy will be at least 2 weeks or at least 5
half-lives (whichever is longer). The half-life for the therapy in question will be
based on published pharmacokinetic literature (abstracts, manuscripts, investigator's
brochures, or drug-administration manuals) and will be documented in the protocol
eligibility document.
- The toxicity from prior therapy should have resolved to Grade =1, however alopecia and
sensory neuropathy Grade =2 not constituting a safety risk based on investigators
judgement is acceptable.
- The use of chemotherapeutic or anti-leukemic agents is not permitted during the study
with the following c: (1) intrathecal (IT) therapy for patients with controlled CNS
leukemia at the discretion of the PI. (2) Use of 1-2 doses of cytarabine (up to 1.5
g/m2 each dose) for patients with rapidly proliferative disease is allowed up to 7
days before the start of study therapy (7 days washout). Since the anti-leukemia
effect of HMA-therapies and kinase inhibitors may be delayed, use of hydroxyurea for
patients with rapidly proliferative disease is allowed on study and before the start
of study therapy and will not require a washout. These medications will be recorded in
the case-report form. (Rationale: Patients with kinase mutations can have very
proliferative disease and the combination can induce differentiation in patients as
part of response)
- Concurrent therapy for CNS prophylaxis or continuation of therapy for controlled CNS
disease is permitted. Patients with a known history of CNS disease must have been
treated with CNS directed therapy, have at least 2 consecutive LPs with no evidence of
CNS leukemia, and must be clinically stable for at least 4 weeks prior to enrollment
and have no ongoing neurological symptoms that in the opinion of the treating
physician are related to the CNS disease
- Serum biochemical values with the following limits:
1. Patients must have adequate renal function as demonstrated by a creatinine
clearance (CrCl) = 50 mL/min calculated by either the Cockcroft-Gault formula,
Modification of Diet in Renal Disease (MDRD) eGFR or measured by 24 hours' urine
collection. For patients with BMI >23, Adjusted body weight and not Ideal Body
Weight is the recommended parameter29, 30.
2. Total bilirubin <1.5 x ULN unless considered due to Gilbert's syndrome
3. Aspartate aminotransferase or alanine aminotransferase =2.0 x ULN (aspartate
aminotransferase or alanine aminotransferase =3.0 x ULN if deemed related to
leukemia by the treating physician)
- White blood cell count <15 x 109/L. Hydroxyurea may be used to reduce the WBC count to
= 15x109/L.
- Ability to understand and provide signed informed consent.
- Females must be surgically or biologically sterile or postmenopausal (amenorrheic for
at least 12 months) or if of childbearing potential, must have a negative serum or
urine pregnancy test within 72 hours before the start of the treatment.
- Women of childbearing potential must agree to use an adequate method of contraception
during the study and until 4 months after the last treatment. Males must be surgically
or biologically sterile or agree to use an adequate method of contraception during the
study until 3 months after the last treatment.
Exclusion Criteria:
- Patients with known allergy or hypersensitivity to ASTX727(Inqovi), ASTX029 or any of
their components.
- Patients with known allergy or hypersensitivity to ASTX727(Inqovi), ASTX029 or any of
their components.
- Patients with any other known concurrent severe and/or uncontrolled medical condition
including but not limited to diabetes, cardiovascular disease including hypertension,
renal disease, or active uncontrolled infection, which could compromise participation
in the study.
- Patients on active antineoplastic or radiation therapy for a concurrent malignancy at
the time of screening. Maintenance therapy, hormonal therapy, or steroid therapy for
well-controlled malignancy is allowed.
- Prior organ transplantation including allogenic stem-cell transplantation within 3
months prior to planned enrollment, active graft versus host disease (GVHD) >Grade 1
or requiring transplant-related immunosuppression with the exception of low dose
cyclosporine and tacrolimus.
- Prior treatment with an ERK inhibitor.
- History or current evidence/risk of retinal vein occlusion (RVO) or central serous
retinopathy (CSR) including:
A) Presence of predisposing factors to RVO or CSR (eg, uncontrolled glaucoma or ocular
hypertension, uncontrolled diabetes mellitus) or b) Visible retinal pathology as assessed
by ophthalmic examination at screening that is considered a risk factor for RVO or CSR such
as:
- Evidence of optic disc cupping or
- Evidence of new visual field defects on automated perimetry or
- Intraocular pressure >21mmHg as measured by tonography.
- Patients with symptomatic CNS leukemia or patients with poorly controlled CNS
leukemia.
- Patients with a known HIV infection that is not well controlled (i.e. any detectable
circulating viral load) at the time of enrollment. No additional screening for HIV
infection is needed.
- Patients with known positive hepatitis B or C infection by serology, with the
exception of those with an undetectable viral load within 3 months (Hepatitis B or C
testing is not required prior to study entry). Subjects with serologic evidence of
prior vaccination to HBV [i.e., HBs Ag-, and anti-HBs+] may participate.
- Patients who have consumed grapefruit, grapefruit products, Seville oranges (including
marmalade containing Seville oranges) or Starfruit within 3 days prior to the
initiation of study treatment.
- Patients who have had any major surgical procedure within 14 days of Day 1.
- Other severe acute or chronic medical conditions that is active and not well
controlled including colitis, inflammatory bowel disease, or psychiatric conditions
including recent (within the past year) or active suicidal ideation or behavior; or
laboratory abnormalities that may increase the risk associated with study
participation or study treatment administration or may interfere with the
interpretation of study results and, in the judgment of the investigator, would make
the patient inappropriate for entry into this study.
- Active and uncontrolled disease (active infection requiring systemic therapy or fever
likely secondary to infection within prior 48 hours): prophylactic antibiotics or
prolonged course of IV antibiotics for controlled infection are allowed, uncontrolled
hypertension despite adequate medical therapy, active and uncontrolled congestive
heart failure NYHA class III/IV, clinically significant and uncontrolled arrhythmia)
as judged by the treating physician.
- Patients unwilling or unable to comply with the protocol.
- Screening 12-lead ECG showing a Baseline average QT interval as corrected by
Fridericia's formula (QTcF) >470 msec. Subjects with left or right bundle branch
block, where QT cannot be accurately assessed, will be allowed into the study after
assessment by institutional cardiologist
- Patients requiring strong CYP3A inducers
