A Study of the Safety and Effectiveness of Using Human Myeloid Progenitor Cells (CLT-008) During Chemotherapy for Acute Myeloid Leukemia

Overview

  • Study type

    Interventional
  • Study phase

    II
  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The purpose of the study is to explore the safety and efficacy of CLT-008 as an extra supportive care measure during induction chemotherapy for patients with acute myeloid leukemia (AML).

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria

  1. Acute myeloid leukemia arising de novo (per European LeukemiaNet)
  2. Treated with any established chemotherapy regimen based on either
    1. 7+3: Standard-dose cytarabine 100-200 mg per meter squared continuous infusion for 7 days with idarubicin 12 mg per meter squared or daunarubicin 45-90 mg per meter squared for 3 days
    2. High-dose cytarabine-based (HIDAC) chemotherapy administering a total cytarabine dose of ≥ 4 g per meter squared alone or in combination with other anti-leukemic agents (for example, anthracyclines, purine nucleoside inhibitors, etoposide, etc.)
  3. Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 at Screening or by the day chemotherapy is initiated
  4. Adequate respiratory function with a room air oxygen saturation of at least 92%
  5. Adequate cardiac function defined as an ejection fraction of at least 45%
  6. Serum bilirubin ≤ 1.5 times the upper limits of normal. Subjects with a history of Gilbert's syndrome may be enrolled if the total bilirubin is < 3 mg/dL with an indirect bilirubin of > 1.5 mg/dL
  7. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 times upper limits of normal prior to chemotherapy
  8. Serum creatinine ≤ 2 times upper limits of normal or estimated glomerular filtration rate ≥ 60 mL/min/1.73 meter squared per Modification of Diet in Renal Disease equation (MDRD)
  9. All subjects, except post-menopausal women, must be willing to utilize a highly effective method of contraception throughout the study
  10. Adequately informed of the nature and risks of the study with written informed consent

 

Exclusion Criteria

  1. Pregnant or breast feeding
  2. Overt central nervous system manifestations of leukemia at diagnosis
  3. Specifically diagnosed and uncontrolled fungal, bacterial, viral, or other infection (e.g. confirmed sepsis, pneumonia, abscess, cellulitis, etc.) at Study Day 0. "Uncontrolled" is defined as exhibiting ongoing signs and symptoms of infection without improvement despite antimicrobial or other treatment.
  4. AML subtype M3 (promyelocytic leukemia)
  5. Previous chemotherapy for AML
  6. History of or current human immunodeficiency virus (HIV) or hepatitis C virus infection
  7. History of or current clinically significant immunodeficiency
  8. Known contraindication to receiving G-CSF
  9. History of or current clinically significant alloimmunization to leukocyte antigens
  10. Participation in another clinical study within 28 days of the day chemotherapy is initiated, in which the study drug or device may influence hematopoiesis   Note: Co-enrollment in another study is allowed in cases where the investigational therapy under study is a version of an acceptable chemotherapy regimen for this study per Inclusion criteria 3.
  11. Receiving any agent concurrently with CLT-008 infusion which inhibits cell division (e.g., methotrexate or hydroxyurea)
  12. Acute or chronic medical disorder that, in the opinion of the investigator or medical monitor, may prevent the subject from completing participation in the study
