Myelodysplastic Syndrome Clinical Trial
Eltanexor and Venetoclax in Relapsed or Refractory Myelodysplastic Syndrome and Acute Myeloid Leukemia
Summary
This phase I trial tests the safety, side effects, and best dose of eltanexor in combination with venetoclax for the treatment of patients with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Eltanexor works by trapping "tumor suppressing proteins" within the cell, thus causing the cancer cells to die or stop growing. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving eltanexor together with venetoclax may be safe, tolerable and/or effective in treating patients with relapsed or refractory MDS or AML.
Full Description
Primary objective:
• To establish the safe and biologically effective dose (BED) of eltanexor in combination with venetoclax in patients with R/R MDS and/or AML
Secondary objectives:
To estimate the complete remission (CR) rate with eltanexor and venetoclax in patients with R/R MDS and/or AML
To assess the overall response rate (ORR) following treatment with eltanexor/venetoclax
To assess the overall survival of patients
To assess the progression free survival (PFS) and duration of response (DOR) in patients treated with eltanexor/venetoclax
Exploratory objectives:
To assess differential response between MDS and AML cohorts
To develop and evaluate a phenotypic flow-based assay to predict response to eltanexor/venetoclax
To assess the effect of mutational changes on response to eltanexor/venetoclax
To measure the rates of measurable residual disease with eltanexor/venetoclax
OUTLINE: This is a dose-escalation study of eltanexor in combination with venetoclax.
Patients receive eltanexor orally (PO) once per day (QD) for 5 days per week for 14, 21, or 28 days every cycle, and venetoclax PO QD on days 1-14 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow aspiration and biopsy and blood sample collection throughout the study.
After completion of study treatment, patients are followed up every 3 months for up to 24 months.
Eligibility Criteria
Inclusion Criteria:
- Age >/= 18 years at the time of signing the Informed Consent Form (ICF); must voluntarily sign an ICF; and must be able to meet all study requirements.
For Myelodysplastic Syndrome (MDS):
Morphologically confirmed diagnosis of MDS with increased blasts (>/= 5%), with a prior DNA methyltransferase inhibitor (DNMTi) treatment and progression after 2 cycles or stable disease after 4 cycles
For Acute Myeloid Leukemia (AML):
Morphologically confirmed diagnosis of AML in accordance with WHO diagnostic criteria that is relapsed or refractory following >/= 1 line(s) of therapy.
WBC must be less than 25,000/ul prior to study start (hydroxyurea allowed).
A bone marrow aspirate must be performed, and tissue collected for entrance to the trial unless circulating blasts >/= 5% in which case, peripheral blood can be used.

Clinically significant cardiovascular disease with major event or cardiac intervention within the past 6 months (e.g. percutaneous intervention, coronary artery bypass graft, documented cardiac heart failure) as determined by the investigator.
Any condition not listed but deemed by the investigator to make the patient a poor candidate for clinical trial and/or treatment with investigational agents.
