  • Patients should not become pregnant or father a baby while on this study because the drugs in this study can affect an unborn baby. Women should not breastfeed a baby while on this study. It is important patients understand the need to use birth control while on this study. It is not anticipated that female patients enrolling in this study will be able to conceive. However, in the rare event that this is possible, 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.
  • Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).

About this study

Official title: An Investigator Sponsored Phase I/II Study of CLAG + Selinexor in Relapsed or Refractory Acute Myeloid Leukemia

Selinexor has shown single-agent activity in a current phase I study enrolling patients with relapsed/refractory AML with durable complete remissions (CR), complete remissions with incomplete hematologic recovery (CRi), partial remissions (PR), and stable disease (SD) observed. Furthermore, common toxicities included nausea, fatigue, and anorexia and were manageable with supportive care agents. Additionally, CLAG chemotherapy has proven activity in relapsed and refractory AML, and has been shown to be a relatively well tolerated regimen without significant non-hematologic toxicity. Given the established role of CLAG chemotherapy, the single agent activity of selinexor, and their non-overlapping toxicities, the investigators propose a phase I/II open label study of selinexor in combination with CLAG for the treatment of patients with relapsed/refractory AML.

Being tested
Selinexor, Cladribine, G-CSF, Cytarabine, Bone marrow biopsy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety and Tolerability of Treatment as Measured by Incidence of Grade 3-4 Adverse Events Occurring in >5% of Participants

    -All adverse events will be classified using the descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) v4.0

    Measured: From start of treatment until 30 days following last day of study treatment or until the start of a subsequent treatment for AML, whichever came first (41 days)

  2. Complete Remission Rate (CR + CRi)

    • Morphologic complete remission (CR): neutrophil count > 1.0 x 109 /L, platelet count ≥ 100 x 109/L, < 5% bone marrow blasts by morphologic review, no Auer rods, no evidence of extramedullary disease. (No requirements for marrow cellularity, hemoglobin concentration).
    • Morphologic complete remission with incomplete blood count recovery (CRi): same as CR but ANC may be <1000/mcl or platelet count <100,000/mcl
    • Participants in the phase I portion of the study, treated at the MTD will count towards the phase II accrual goal for evaluation of the primary endpoint.

    Measured: Median follow-up of 34 days

Secondary outcomes (7)
  1. Time to Platelet Engraftment

    -Time to platelet engraftment: Defined as the date of the first dose of study drug to the date that the platelet count is >100,000/mm^3 in the absence of platelet transfusions.

    Measured: 56 days

  2. Time to Neutrophil Engraftment

    -Time to neutrophil engraftment: Defined as the date of the first dose of study drug to the date that the absolute neutrophil count is >1,000/mm3

    Measured: Up to 2 years

  3. Event-free Survival

    Event-free survival (EFS): Defined as the interval from the date of first dose of study drug to date of treatment failure including progressive disease, recurrence, or discontinuation for any reason (including toxicity, patient preference, initiation of new treatment without documented progression, or death due to any cause).

    Measured: Up to 2 years (median follow-up of 307 days)

  4. Duration of Remission

    -Duration of remission (DOR): Defined as the interval from the date complete remission is documented to the date of recurrence.

    Measured: Up to 2 years

  5. Relapse-free Survival

    Relapse-free survival (RFS): For patients achieving a complete remission, defined as the interval from the date of first documentation of a leukemia free state to date of recurrence or death due to any cause.

    Measured: Median follow-up of 307 days

  6. Overall Survival

    Overall survival (OS): Defined as the date of first dose of study drug to the date of death from any cause. OS will be evaluated at 3 month intervals for at least 12 months and up to a maximum of 2 years.

    Measured: Up to 2 years (median follow-up of 307 days)

  7. Number of Participants Who Were Able to Undergo Hematopoietic Stem Cell Transplantation

    Allogeneic stem cell transplant utilization: the number of patients proceeding to allogeneic transplant within 2 months following end of study without any additional salvage therapy following study treatment.

    Measured: Up to 2 years (median follow-up of 307 days)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Selinexor, Cladribine and G-CSF in people with Acute Myeloid Leukemia, run by Washington University School of Medicine at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Mar 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety and Tolerability of Treatment as Measured by Incidence of Grade 3-4 Adverse Events Occurring in >5% of Participants (time frame: From start of treatment until 30 days following last day of study treatment or until the start of a subsequent treatment for AML, whichever came first (41 days)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2020; AzTrials last refreshed its copy on 7 Nov 2026.
