Purpose

A Phase III study to evaluate the safety and efficacy of CPI-613® (devimistat) in combination with High Dose Cytarabine and Mitoxantrone in comparison with high dose Cytarabine and Mitoxantrone and control sub-groups: combination of Mitoxantrone, Etoposide and Cytarabine (MEC) and combination of Fludarabine, Cytarabine, and Filgrastim (FLAG) in older patients with relapsed/refractory Acute Myeloid Leukemia. CPI-613® (devimistat) targets the altered energy metabolism and processes for production of ATP and essential bio-intermediates unique to and characteristic of most cancer cell types. The addition of CPI-613® (devimistat) to high dose cytarabine and mitoxantrone (CHAM) will improve the complete remission (CR) rate in patients 50 years or older with relapsed or refractory AML when compared to HAM alone or other control sub groups.

Inclusion Criteria

  1. Patient has provided an informed consent prior to initiation of any study specific activities/procedures
  2. Males and females age ≥ 50 years must have histologically documented AML that is relapsed from, or refractory to, prior standard therapies
  3. Refractory is defined as failure to achieve CR or CRi following:
  4. At least one cycle of any anthracycline, cytarabine or fludarabine containing induction regimen or persistence of disease on a nadir marrow following at least one cycle of any anthracycline, cytarabine or fludarabine containing induction regimen
  5. Persistent disease after at least 2 cycles of a hypomethylating agent (azacytidine or decitabine) with or without venetoclax
  6. Relapse is defined as development of recurrent AML (as described by Döhner et al, 2017)6 after CR or CRi has been achieved with a prior chemotherapy or after disease progression on a hypomethylating agent with or without venetoclax
  7. ECOG PS 0-2
  8. Expected survival greater than 3 months
  9. Women of child-bearing potential (i.e. women who are pre-menopausal or < 2 years post menopausal or not surgically sterile) must practice a highly effective method of birth control consistent with local regulations regarding the use of birth control methods. Examples: use of oral, injected or implanted hormonal methods of contraception; placement of an intra uterine device (IUD) or intrauterine system (IUS); male partner sterilization (the vasectomized partner should be the sole partner for that subject); true abstinence during and for 6 months after the last administered dose of CHAM or HAM therapy and control sub-groups (MEC and FLAG), and must have a negative serum pregnancy test within 1 week prior to treatment initiation and at 1st day of each cycle and at the end of systemic exposure. (Note: pregnant patients are excluded because the effects of CPI-613® (devimistat) on a fetus are unknown)
  10. Fertile men who are sexually active with a woman of childbearing potential and has not had a vasectomy must agree to use a barrier method of birth control eg, either condom with spermicidal foam/gel/film/cream/suppository or partner with occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository during the study period and up to 6 months after completion of the study screening, unless documentation of infertility exists
  11. Good state of mental health, ability to understand and willingness to sign the informed consent form (ICF)
  12. No radiotherapy, treatment with cytotoxic chemotherapy, treatment with biologic agents or any anti-cancer therapy for R/R AML within the 1 week prior to treatment with CPI-613® (devimistat). Hydroxyurea and/or venetoclax and oral tyrosine kinase (FLT3) or Isocitrate Dehydrogenase 1 and 2 (IDH1/2), BCL-2 or hedgehog inhibitors being used with Grade ≤ 2 toxicity can be taken until the day prior to starting of CHAM or HAM therapy or control sub-groups (MEC and FLAG). Previous exposure to a hypomethylating agent either alone or in combination with Isocitrate Dehydrogenase 1 and 2 (IDH1/2), BCL-2 or hedgehog inhibitors are allowed until the day prior to starting of CHAM or HAM therapy and control sub-groups (MEC and FLAG). Patients must have fully recovered from the acute, non-hematological, non-infectious toxicities of any prior treatment with cytotoxic drugs, radiotherapy or other anti-cancer modalities with the exception of alopecia (returned to baseline status as noted before most recent treatment). Patients with persisting, non-hematologic, non-infectious toxicities from prior treatment Grade ≤ 2 are eligible but must be documented as such
  13. Laboratory values ≤ 2 weeks before dosing must be:
  14. Adequate hepatic function (aspartate aminotransferase/serum glutamic-oxaloacetic transaminase [AST/SGOT] ≤ 5 x upper limit of normal [ULN], alanine aminotransferase/serum glutamic oxaloacetic transaminase [ALT/SGPT] ≤ 5 × ULN, bilirubin ≤ 1.5 × ULN)
  15. Adequate renal function (serum creatinine clearance ≥ 60 mL/min per CockCroft Gault formula)
  16. Adequate coagulation (International Normalized Ratio [INR] must be < 1.7 unless on vitamin k antagonist anticoagulation)
  17. Left Ventricular Ejection Fraction (LVEF) by Transthoracic Echocardiogram (TTE) or Multigated Acquisition Scan (MUGA) or cardiac Magnetic Resonance Imaging (MRI), sufficient to safely administer mitoxantrone. Subjects must have an LVEF ≥ 45%

  20. Allow only patients who experienced relapse after 1 year from previous HiDAC treatment or who didn't receive HiDAC previously (Note: This inclusion applies only to South Korea)

Exclusion Criteria

  1. Patients who have received cytotoxic chemotherapy treatment for their current relapsed or refractory AML. (Treatment with hypomethylating agents (decitabine or azacytidine) either alone or in combination with venetoclax are allowed until the day prior to starting of CHAM or HAM therapy and control sub-groups (MEC and FLAG).
