Phase III Multicenter Open-Label Randomized Trial to Evaluate Efficacy and Safety of CPI-613 in Combination With High Dose Cytarabine and Mitoxantrone (CHAM) Compared to High Dose Cytarabine and Mitoxantrone (HAM) in Older Patients (≥60 Years) With Relapsed/Refractory Acute Myeloid Leukemia (AML)

A Phase III study to evaluate the safety and efficacy of CPI-613 in combination with High Dose Cytarabine and Mitoxantrone in comparison with high dose Cytarabine and Mitoxantrone in older patients with relapsed/refractory Acute Myeloid Leukemia. CPI-613 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 to high dose cytarabine and mitoxantrone (CHAM) will improve the complete remission (CR) rate in patients 60 years or older with relapsed or refractory AML when compared to HAM alone.

INCLUSION CRITERIA:

         1. Patient has provided an informed consent prior to initiation of any study specific activities/procedures.

         2. Males and females age ≥ 60 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:

             1. Two standard dose Cytarabine based induction cycles or one HiDAC based cycle, or

             2. Failure to respond to one cycle of either standard dose or HiDAC (defined as no decrease in marrow blast percentage from diagnosis on Day 14 marrow), or

             3. No response after at least 3 cycles of a hypomethylating agent (azacytidine or decitabine).

         4. Relapse is defined as development of recurrent AML (as described by Döhner et al, 2010)6 after CR or CRi has been achieved with a prior chemotherapy or after disease progression on a hypomethylating agent.

         5. ECOG PS 0-2.

         6. Expected survival >3 months.

         7. Women of child-bearing potential (i.e. women who are pre-menopausal or < 2 years post menopausal or not surgically sterile) must use 2 effective contraceptive methods (abstinence, intrauterine device [IUD], oral contraceptive, injectable or implantable agent/device or double barrier device (diaphragm + spermicide) during and for 6 months after the last administered dose of CHAM or HAM therapy, and must have a negative serum pregnancy test within 1 week prior to treatment initiation (Note: pregnant patients are excluded because the effects of CPI 613 on a fetus are unknown).

         8. Fertile men must practice effective contraceptive methods (condom + spermicide) during the study period and up to 6 months after completion of the study screening, unless documentation of infertility exists.

         9. Good state of mental health, ability to understand and willingness to sign the informed consent form (ICF).

         10. No radiotherapy, treatment with cytotoxic chemotherapy, treatment with biologic agents or any anti-cancer therapy within the 2 weeks prior to treatment with CPI 613. Hydroxyurea and oral tyrosine kinase (FLT3) or Isocitrate Dehydrogenase 1 and 2 (IDH1/2) inhibitors being used with Grade ≤ 2 toxicity can be taken until the day prior to starting study therapy. Previous exposure to a hypomethylating agent either alone or in combination with Venetoclax is allowed. 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.

         11. Laboratory values ≤ 2 weeks before dosing must be:

             - 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).

             - Adequate renal function (serum creatinine clearance ≥ 60 mL/min per CockCroft Gault formula).

             - Adequate coagulation (International Normalized Ratio [INR] must be < 1.7 unless on vitamin k antagonist anticoagulation).

         12. Left Ventricular Ejection Fraction (LVEF) by Transthoracic Echocardiogram (TTE), Multigated Acquisition Scan (MUGA) or cardiac Magnetic Resonance Imaging (MRI), sufficient to safely administer mitoxantrone. Subjects must have an LVEF ≥ 45%.

         13. No marked baseline prolongation of QT/QTc interval (repeated exhibition of a QTc interval > 450 ms for male and > 470 ms for female patients).

         14. No history of additional risk factors for torsade de pointes (e.g. clinically significant heart failure, hypokalemia, immediate family history of Long QT Syndrome).

        EXCLUSION CRITERIA:

         1. Patients who have received previous cytotoxic chemotherapy treatment for their relapsed or refractory AML. Previous treatment with hypomethylating agents (decitabine or azacytidine) either alone or in combination with Venetoclax is allowed. Targeted therapies including FLT3 or IDH1/2 inhibitors or Hydrea are allowed. Targeted therapies and Hydrea may be taken until the day prior to starting CHAM or HAM therapy.

         2. History or evidence of any other clinically significant disorder, condition or disease (e.g. symptomatic congestive heart failure, unstable angina pectoris, symptomatic myocardial infection, uncontrolled cardiac arrhythmia, pericardial disease or heart failure New York Heart Association Class III or IV), or severe debilitating pulmonary disease, that would potentially increase patients' risk for toxicity and in the opinion of the Investigator, would pose a risk to patient safety or interfere with the study evaluation, procedures or completion.

         3. Patients with active Central Nervous System (CNS) involvement (leukemic infiltration, blast in the spinal fluid).

         4. Any active uncontrolled bleeding, and any patients with a bleeding diathesis (e.g. active peptic ulcer disease).
