Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 60 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Written informed consent.
  • Either de novo or secondary AML by 2008 World Health Organization (WHO) classification.
  • A bone marrow biopsy and aspirate sample must be obtained between Day -14 to Day -1, and this sample must be confirmed to be adequate for morphologic analysis of marrow cellularity and blast percentage before the first dose of KX2-391 is administered.
  • A bone aspirate sample (with or without biopsy) must be obtained after the patient signs the informed consent document and be submitted for baseline pharmacodynamic assessment. Although this will usually be obtained as part of the baseline assessment marrow biopsy and aspirate procedure described above, if a complete marrow evaluation was performed prior to the patient signing informed consent, a dedicated bone marrow aspiration for this sample can be performed after the patient signs informed consent, so long as the pre-consent biopsy and aspirate procedure were done within 14 days of the first dose of KX2-391.
  • Adults age ≥ 60 years of age
  • Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
Show all 10Show fewer
  • Life expectancy of at least 6 weeks from first day of study drug administration
  • Adequate liver function (AST/ALT < 3 x upper limit of normal (ULN), Alk Phos < 2.5 x ULN, and Direct Bilirubin < 1.5 x ULN)
  • Adequate renal function (serum creatinine < 1.5 x ULN)
  • Documented QTc ≤ 0.48 seconds within 14 days of first dose of KX2-391

Who cannot join

  • Subjects with acute promyelocytic leukemia (APL, AML FAB type M3), or chronic myelogenous leukemia (CML).
  • Have not resolved toxicity from previous anticancer treatments or investigational agents, other than hematologic toxicities or alopecia, to ≤ Grade 1 according to the most recent CTCAE guidelines.
  • Subjects with rapidly proliferative AML that is likely to require treatment within the next 30 days (e.g. hydroxyurea).
  • Received an investigational agent within 5 half-lives of that agent from the anticipated Cycle 1 Day 1 of treatment with KX2-391.
  • Have clinical evidence of central nervous system involvement by AML or other malignancy.
  • History of major surgery to the upper gastrointestinal tract, or have a history of inflammatory bowel disease, malabsorption syndrome, or other medical condition that may interfere with oral drug absorption.
Show all 17Show fewer
  • Uncontrolled hypertension (at time of dosing).
  • Other medical conditions which, in the opinion of the investigator, make it undesirable for the subject to participate in the study.
  • Known history of hepatitis B, C, or human immunodeficiency (HIV) infection.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection. Patients receiving intravenous antibiotics for infections that are under control may be included in this study.
  • Subjects who are unwilling or unable to comply with the protocol.
  • Subjects who are taking moderate or strong CYP450 3A4 modulators, with the exception of fluconazole (see Appendix 2 for list of medications currently known to be moderate or strong CYP450 3A4 modulators). Subjects who can safely discontinue these medications can become eligible for this trial.
  • Subjects receiving azole-based antifungal prophylaxis other than fluconazole (see Appendix 2) who are unable to switch their prophylaxis to fluconazole, or discontinue antifungal prophylaxis, for 7 days prior to first day of study drug administration.
  • Active cancer, other than AML, requiring systemic chemotherapy or biological therapy within 6 months of study entry. Patients who have received only hormonal therapy in the neoadjuvant or adjuvant setting in the past 6 months may participate in this study.
  • Symptomatic congestive heart failure, unstable angina, or cardiac arrhythmia.
  • Other conditions that could jeopardize the subject's ability to comply with the protocol, including, but not limited to, dementia, psychosis, or other major psychiatric disorder
  • Pregnant or breast feeding

About this study

Official title: A Phase 1b Rising Multiple-Dose Study to Evaluate Safety, Tolerability and Activity of KX2-391 in Elderly Subjects With Acute Myeloid Leukemia Who Are Refractory to or Have Declined Standard Induction Therapy

This Phase 1b study will determine the maximum tolerated dose of KX2-391 given as a once-daily dose, in elderly patients with acute myelogenous leukemia.

Read the detailed description

KX2-391 has been evaluated in a Phase 1 dose escalation study in patients with solid tumors using twice-daily dosing. This study will employ the Storer's two-stage design to determine the maximum tolerated dose of KX2-391 mono-therapy,given as a once-daily oral dose,in elderly patients with acute myelogenous leukemia (AML) who are refractory to or have declined standard induction therapy. The safety, tolerability, pharmacokinetics and activity of KX2-391 will be evaluated.

Study groupRoleWhat they receive
TreatmentExperimentalSubjects will be enrolled into a 28-day dose-escalation study. If no DLT's are observed during the first 28 days, subjects are eligible to continue treatment in the Extension Phase and can remain on treatment until toxicity occurs or until disease progression.
Receives: Drug: KX2-391

What is being measured

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

  1. To determine the maximum tolerated dose of KX2-391 when given once-daily to AML patients.

    The MTD will be used to determine the recommended Phase 2 dose that is associated with an approximately 33% DLT rate during the first 28 days of treatment in elderly patients with AML

    Measured: 28 days

Secondary outcomes (1)
  1. Evaluate pharmacokinetics, pharmacodynamics and activity of KX2-391.

    The pharmacokinetics and pharmacodynamics of KX2-391 will be evaluated in AML patients by measuring serum and bone marrow levels of drug and evaluating the disruption of microtubule networks in these samples to determine whether target inhibition has occurred at the doses tested. Hematological and bone marrow response will be assessed according to International Working Group (IWG)-AML criteria.

    Measured: 28 days

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 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.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To determine the maximum tolerated dose of KX2-391 when given once-daily to AML patients. (time frame: 28 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01397799, which also lists 1 linked publication.

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.
