Selinexor With Fludarabine and Cytarabine for Treatment of Refractory or Relapsed Leukemia or Myelodysplastic Syndrome

A Phase I/II Study of the Selective Inhibitor of Nuclear Export Selinexor (KPT-330) in Combination With Fludarabine and Cytarabine in Patients With Refractory or Relapsed Leukemia or Myelodysplastic Syndrome

Summary

The purpose of this study is to test the safety of selinexor (KPT-330) and to find the highest dose of selinexor (KPT-330) that can be given safely when it is combined with two chemotherapy drugs (fludarabine and cytarabine). This study will be done in two parts: Phase I and Phase II. The goal of Phase I is to find the highest tolerable dose of selinexor (KPT-330) that we can give to patients with leukemia or MDS, when it is combined with fludarabine and cytarabine. The goal of the subsequent Phase II portion of the study (insert NCT ID of SELHEM-2) is to give the highest dose of selinexor (KPT-330) in combination with fludarabine/cytarabine that was found in Phase I to be safe for children with leukemia or MDS. The investigators will examine the effect of this combination treatment. PRIMARY OBJECTIVE: * Determine a tolerable combination of selinexor, fludarabine, and cytarabine in pediatric patients with relapsed or refractory hematologic malignancies included acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), mixed phenotype acute leukemia (MPAL) and myelodysplastic syndrome (MDS). SECONDARY OBJECTIVES: * To characterize the pharmacokinetics of selinexor, when administered in tablet form, after the first dose and at steady-state, as well as in combination with fludarabine and cytarabine * To estimate the overall response rate of selinexor given with fludarabine and cytarabine in patients with relapsed or refractory hematologic malignancies

Detailed Description

Phase I will characterize the dose-limiting toxicities (DLTs) and determine the maximum tolerated dose (MTD) or recommended phase II dose of selinexor when given in combination with fludarabine and cytarabine. Selinexor will be given twice weekly (on days 1 and 3) and escalated or de-escalated based on tolerability. The rolling-6 design will be used for this study. Only cycle 1 of therapy will be used to evaluate the DLT. Two to six participants can be concurrently enrolled onto a dose level, dependent on 1) the number of participants enrolled at the current dose level, 2) the number of participants who have experienced DLT at the current dose level, and 3) the number of participants entered but with tolerability data pending at the current dose level. Accrual is suspended when a cohort of six has enrolled or when the study endpoints have been met. Once the recommended Phase II dose is determined, additional patients will be enrolled, if necessary, so that at least 6 subjects are treated with the recommended Phase II dose to determine MTD. After the MTD is determined, 12 additional patients will be treated at this dose level for further evaluation of tolerability and response.

Inclusion Criteria

•Participants must have a diagnosis of AML, MDS, ALL or MPAL and must have disease that has relapsed or is refractory to chemotherapy, or that has relapsed after hematopoietic stem cell transplantation (HSCT)
•* Refractory disease is defined as persistent disease after at least two courses of induction chemotherapy.
•* Patients with AML, MPAL or MDS are eligible at first or subsequent relapse, whereas patients with ALL are eligible at second or subsequent relapse or any relapse that is refractory to salvage chemotherapy.
•* Patients with AML or ALL must have ≥ 5% leukemic blasts in the bone marrow or increasing levels of MRD in the bone marrow as assessed by flow cytometry. If an adequate bone marrow sample cannot be obtained, patients may be enrolled if there is unequivocal evidence of leukemia in the peripheral blood.
•Adequate organ function defined as the following:
•* Direct bilirubin ≤ 1.5 x institutional upper limit of normal (IULN)
•* AST (SGOT)/ALT (SGPT) \< 3 x IULN
•* Creatinine within normal institutional limits for age
•Prothrombin time (PT) and partial thromboplastin (PTT) ≤ 1.5 x IULN.
•Age criteria: Patients treated at collaborating sites and current St. Jude patients who are on therapy or within 3 years of completion of therapy must be ≤ 24 years old. All other St. Jude patients must be \< 21 years old.

Exclusion Criteria

•History of cerebellar toxicity or cerebellar neurological findings on exam.
•Must not be pregnant or breastfeeding. Female patients of child-bearing potential must agree to use dual methods of contraception and have a negative serum pregnancy test at screening, and male patients must use an effective barrier method of contraception if sexually active with a female of child-bearing potential. Acceptable methods of contraception are condoms with contraceptive foam, oral, implantable or injectable contraceptives, contraceptive patch, intrauterine device, diaphragm with spermicidal gel, or a sexual partner who is surgically sterilized or post-menopausal. For both male and female patients, effective methods of contraception must be used throughout the study and for three months following the last dose.
•Use of investigational agents, with the exception of gemtuzumab ozogamicin, within 30 days.
•Any significant concurrent disease, illness, or psychiatric disorder that would compromise patient safety or compliance, study participation, follow up, or interpretation of study research.
•Unstable cardiovascular function:
•* symptomatic ischemia
•* congestive heart failure NYHA Class \> 3
•* myocardial infarction (MI) within 3 months
•Uncontrolled infection requiring parenteral antibiotics, antivirals, or antifungals within one week prior to first dose. Infections controlled on concurrent anti-microbial agents are acceptable, and anti-microbial prophylaxis per institutional guidelines are acceptable.
•Known human immunodeficiency virus (HIV) infection (pre-study testing not required).
