Study for Patients with Acute Myeloid Leukemia

Clinical Trial Title

A phase 2b, open-label, single arm, multi-center study to assess the efficacy and safety of BST-236 as a single agent in adults with newly-diagnosed acute myeloid leukemia, not eligible for standard induction therapy.

National Clinical Trial Number:


Clinical Trial Protocol Description:

The purpose of this study is to measure the safety of BST-236 and how effective it is in treating patients with newly-diagnosed acute myeloid leukemia (AML) who are not eligible for standard induction chemotherapy. The study drug, BST-236 is not approved by the FDA, and the use of BST-236 to treat acute myeloid leukemia is experimental. This will be done by administration of BST–236 (an investigational drug also called the study drug) 6 days in a row per cycle of treatment. The treatment cycles will be repeated up to 4 times during the study depending on your response to the treatment.

Clinical Trial Eligibility Criteria:

In order to participate you must meet the following criteria:

  • Are an adult ≥18 years of age.
  • Have AML according to the 2016 revision to the World Health Organization (WHO) classification of myeloid neoplasms and acute leukemia: ≥20% blasts in peripheral blood or marrow:
    • de-novo AML
    • AML secondary to MDS
    • AML secondary to exposure to potentially leukemogenic therapies or agents (e.g. radiation therapy, alkylating agents, topoisomerase II inhibitors) with the primary malignancy in remission for at least 2 years
  • Are not eligible for standard induction chemotherapy:
    • Age ≥75 years
    • Age ≥18 years with at least one of the following comorbidities:
      • Clinically significant heart or lung comorbidities, as reflected by at least one of:
        • Left ventricular ejection fraction (LVEF) ≤50%
        • Lung diffusing capacity for carbon monoxide (DLCO) ≤65% of expected
        • Forced expiratory volume in 1 second (FEV1) ≤65% of expected
      • Chronic stable angina or congestive heart failure controlled with medication
      • Other comorbidity that the Investigator judges as incompatible with intensive remission induction chemotherapy, which must be documented
    • Contraindication(s) to anthracycline therapy (must be documented)
  • Have creatinine clearance (estimated by the Cockroft-Gault (C-G) measured by 24 hours urine collection) ≥45 mL/min.
  • Have liver enzymes (aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) ≤2.5 times the upper limits of normal (ULN) if not attributed to leukemia or < 5 x ULN if related to leukemic involvement.
  • Have total bilirubin ≤1.5 x ULN unless due to suspected history of Gilbert's disease.
  • Have an Eastern Cooperative Oncology Group (ECOG) performance status at screening: ≤3 for patient at the age of <75 years; ≤2 for patients at the age of ≥75 years.
  • Are prepared and able to give written (signed and dated) informed consent, which includes compliance with study requirements and restrictions prior to admission to the study.
  • Women of reproductive potential must have a negative serum pregnancy test within 48 hours of the first day of any BST-236 treatment course.
  • Women or men of reproductive potential must use (or have his/her partner use) two forms of effective birth control methods starting from 1 month prior to screening and until 3 months following the last BST-236 administration day. (Acceptable methods of birth control in this study include: surgical sterilization, intrauterine devices, oral contraceptives, contraceptive patch, long-acting injectable contraceptives, partner’s vasectomy, or double-barrier method condom or diaphragm with spermicide)
  • Voluntarily sign and date an ICF, approved by an Independent Ethics Committee (IEC)/Institutional Review Board (IRB), prior to the initiation of any screening or study-specific procedures.
  • Are able to adhere to the study visit schedule and other protocol requirements Inclusion criteria for reinduction treatment:
    • Bone marrow morphological response (less than 25% blasts in BM or a reduction from baseline of at least 50% in BM blasts)
    • Creatinine clearance (estimated by the C-G or measured by 24 hours urine collection) ≥45 mL/min during 48 hours prior to the first dose of reinduction
    • Liver enzymes (AST and/or ALT) ≤2.5 x ULN if not attributed to leukemia or <5X ULN if related to leukemia involvement
    • Total bilirubin ≤1.5 x ULN unless due to suspected history of Gilbert's disease

Inclusion criteria for consolidation treatment:

  • Patient in CR/CRh/CRi.
  • Creatinine clearance (estimated by the C-G or measured by 24 hours urine collection) ≥45 mL/min during 48 hours prior to the first dose of consolidation.
  • Liver enzymes (AST and/or ALT) ≤2.5 x ULN.
  • Total bilirubin ≤1.5 x ULN unless due to suspected history of Gilbert's syndrome.
