Full Description

Primary Objective:

To compare survival of patients treated with a combination of pevonedistat and azacitidine after failure of DNA methyltransferase inhibitors (DNMTi) to historical survival for patients with relapsed/refractory myelodysplastic syndrome (MDS) or myelodysplastic/ myeloproliferative overlap syndromes (MDS/MPN) who are ineligible for hematopoietic stem cell transplant (HSCT)

Secondary Objectives:

To determine the rate of hematologic improvement (HI) in patients with relapsed/refractory MDS or MDS/MPN treated with pevonedistat and azacitidine after DNMTi failure
To determine the complete remission (CR) and marrow CR rates in patients with relapsed/refractory MDS or MDS/MPN treated with pevonedistat and azacitidine after DNMTi failure
To determine the reduction of bone marrow blasts in patients with relapsed/refractory MDS or MDS/MPN treated with pevonedistat and azacitidine after DNMTi failure

Exploratory Objectives:

To correlate the mutation burden in patients with relapsed/refractory MDS or MDS/MPN with response to treatment with pevonedistat and azacitidine
To correlate genomic aberrations with rate of response and survival in relapsed/refractory MDS or MDS/MPN patients treated with pevonedistat and azacitidine
To measure the effect of pevonedistat treatment in combination with azacitidine on quality of life in patients with relapsed/refractory MDS or MDS/MPN
To define epigenetic biomarkers for pevonedistat use in relapsed/refractory MDS or MDS/MPN

Eligibility Criteria

Inclusion:

Signed and dated voluntary written informed consent before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.
Male or female ≥ 18 years of age.
Morphologically confirmed diagnosis of MDS or MDS/MPN in accordance with WHO diagnostic criteria.
ECOG performance status of 0, 1 or 2.
Expected survival ≥ 3 months after consenting.

Refractory/relapsed disease following DNMTi failure. Refractory disease defined as either:

failure to achieve an objective response after at least 4 cycles of DNMTi therapy, or
failure to achieve an objective response with clear progressive disease on bone marrow biopsy after at least 2 cycles of DNMTi therapy. Relapsed disease is defined as having progressive disease after achieving an objective response after at least 2 cycles of DNMTi therapy.

Previous DNMTi therapy may include 5'azacitidine, decitabine, or DNMTi therapy currently in clinical trials (e.g. SGI-110 (guadecitabine), ASTX727 or CC-486).To be considered DNMTi treatment failure, during each prior treatment cycle, patients must have received equivalent to minimum dosing of:

decitabine 15mg/m2 daily x 5 days, or

5'azacitidine 50mg/m2 IV/SC daily x 5 days,

SGI-110 (guadecitabine) 60mg/m2 SC daily x 5 days, or

oral DNMTi therapy with ASTX727 20/100mg daily x 5 days, or

oral DNMTi therapy with CC-486 200mg daily x 14 days

Recovery to ≤ Grade 1 or baseline of any toxicity due to prior systemic treatments, excluding alopecia.
Patient consent to collection of fresh bone marrow biopsy and aspirate for exploratory research obtained from a procedure performed no more than 28 days prior to initiating treatment on Cycle 1, Day 1. Requirement for bone marrow biopsy may be waived with approval of the study chair in the event that a bone marrow biopsy cannot be obtained.

Clinical laboratory values as specified below:

Serum albumin > 2.7 g/dL
Total bilirubin ≤ 1.5 x ULN
ALT and AST ≤ 2 x ULN
Calculated creatinine clearance ≥ 50 mL/min (per the Cockcroft-Gault formula)
WBC ≤ 50,000/µL (use of hyroxyurea is permitted)
Hgb <8g> Women of childbearing potential must have a negative serum pregnancy test; and additionally agree to simultaneously use at least 2 methods of effective contraception or abstain from heterosexual intercourse from the time of signing consent, and until 4 months after patient's last dose of protocol-indicated treatment. Periodic abstinence (e.g. calendar,ovulation, symptothermal, postovulation methods for the female partner) and withdrawal are not acceptable methods of contraception.

Women of child bearing potential are defined as those not surgically sterile or not post-menopausal. If a female patient has not had a bilateral tubal ligation, a bilateral oophorectomy, or a complete hysterectomy; or has not been amenorrheic for at least 1 year in the absence of an alternative medical cause, then patient will be considered a female of childbearing potential. Postmenopausal status in females under 55 years of age should be confirmed with a serum FSH level within laboratory reference range for postmenopausal women.

- Men, even if surgically sterilized (i.e. status post-vasectomy), who are sexually active with women of childbearing potential must agree to follow instructions for effective barrier contraception from the time of signing consent and until 4 months after last dose of protocol-indicated treatment. Periodic abstinence (e.g. calendar, ovulation, symptothermal, postovulation methods for the female partner) and withdrawal are not acceptable methods of contraception.

Exclusion:

Diagnosis of acute myeloid leukemia (i.e. ≥ 20% peripheral or marrow blasts).
Any HSCT within 6 months prior to signing informed consent.
Any patient who is eligible for HSCT at the time of study screening.
Clinically significant graft versus host disease (GVHD) or GVHD requiring initiation of treatment or treatment escalation within 21 days, and/or > Grade 1 persistent or clinically significant non-hematologic toxicity related to HSCT
Any previous treatment with pevonedistat or other NEDD8 inhibitor.
Treatment with any investigational products within 14 days before the first dose of protocol-indicated treatment.
Systemic antineoplastic therapy or radiotherapy within 14 days before the first dose of any study drug.
Major surgery requiring general anesthesia within 14 days before the first dose of any study drug or a scheduled surgery during study period. (Placement of a central line or port-a-catheter is acceptable within this time frame and does not exclude the patient.)
Treatment with clinically significant metabolic CYP3A inducers within 14 days before the first dose of study drug. Clinically significant CYP3A inducers are not permitted during the study.
Prolonged QTc interval > 500 msec, calculated according to Fredericia's formula

Arrhythmia (e.g. history of polymorphic ventricular fibrillation or torsade de pointes). Patients with symptomatic atrial fibrillation (Afib) incompletely controlled medically, or controlled by device (e.g. pacemaker) or by ablation in the past 6 months are excluded. However, patients with stable, AFib for a period of at least 6 months, whose Afib is controlled with medication, or who have a history of paroxysmal AFib are permitted to enroll;

Note: Patients who have isolated positive hepatitis B core antibody (i.e. in the setting of negative hepatitis B surface antigen and negative hepatitis B surface antibody) must have an undetectable hepatitis B viral load.
Known human immunodeficiency virus (HIV) seropositivity.
Any serious concurrent condition that could, in the investigator's opinion, significantly interfere with completion of study procedures or protocol compliance.
