Overview
Brief Summary
This is an open label phase I clinical trial of hydroxychloroquine (HCQ) ,when it is combined with the usual medications for acute myeloid leukemia, mitoxantrone and etoposide. The purpose of this study is to find the safest and most effective dose of hydroxychloroquine with these medications. The investigators will be testing to see if it can increase the effectiveness of mitoxantrone and etoposide.
Detailed Description
Hydroxychloroquine is not FDA (United States Food and Drug Administration) approved for AML and is considered an investigational drug in this study. It has helped make chemotherapy more effective in animals. The investigators will be testing to see if it can increase the effectiveness of mitoxantrone and etoposide. It has been combined with other types of chemotherapy for humans with other types of cancer. Most of the patients were able to take hydroxychloroquine safely at the doses studied in this clinical trial. Hydroxychloroquine is approved by the FDA for malaria, rheumatoid arthritis, and other autoimmune diseases. Mitoxantrone is approved by the FDA for use in AML, and it is one of the most common drugs used in the treatment of AML. Etoposide is not approved by the FDA for AML. It is approved for small cell lung cancer and testicular cancer. It is commonly used in AML. The primary objective of this trial is to determine the recommend phase 2 dose (RP2D) for HCQ combined with mitoxantrone and etoposide, while secondary objectives include efficacy estimates of this combination at the RP2D, a safety and tolerability profile of this combination, as well as the correlation of pharmacodynamic assessments of autophagy inhibition with dose and clinical response.

Eligibility Criteria
Inclusion Criteria
- •Able to understand and have the ability to provide written consent
- •Age \> 18 years old to \<80 years old
- •Patients with AML in the first morphologic relapse as defined by \>5% reappearance of leukemia blasts in the bone marrow not attributable to any other cause (Appendix I) who have not yet received chemotherapy for the current relapse
- •Eastern Cooperative Oncology Group Performance Status of 0 -2 (see Appendix II)
- •Adequate organ function
- •Serum creatinine ≤ 1.5 mg/dl and calculated creatinine clearance ≥ 50 mL/min (using the Cockcroft-Gault equation CL creatinine = (140-age) x body mass X 0.85 if female)/72 x creatinine where age is given in years, body mass is given in kg and creatinine is given in mg/dL)
- •Aspartate aminotransferase (AST) ≤ 5x the upper limit of normal Alanine aminotransferase (ALT) \< 5x the upper limit of normal
- •Direct bilirubin ≤ 1.5 mg/dl Note: As many eligible patients will be pancytopenic secondary to their disease or prior treatments, hematologic abnormalities will not be used as a criteria for entry or exclusion
- •Left ventricular ejection fraction (LVEF) ≥50 %
- •Females of child-bearing potential must have a negative pregnancy test during screening and all subjects must agree to use an effective method of contraception. A woman is eligible to enter and participate in the study if she is of:
Exclusion Criteria
- •Acute promyelocytic leukemia
- •Prior chemotherapy regimen given for 1st relapse, not including the use of hydroxyurea or plasmapheresis that is used prior to the initiation of chemotherapy.
- •Previous use of mitoxantrone and etoposide combination therapy within the preceding 180 days of screening.
- •Symptomatic central nervous system (CNS) involvement
- •Uncontrolled, life-threatening infection that is not responding to antimicrobial therapy
- •History of psychiatric disorder which may compromise compliance with the protocol or which does not allow for appropriate informed consent
- •Current receiving any other anti neoplastic investigational agents
- •Prior autologous or allogeneic stem cell transplantation
- •Concurrent malignancy. Exceptions: Patients who have been disease-free for 5 years, or subjects with a history of completely resected non-melanoma skin cancer or successfully treated in situ carcinoma are eligible. Subjects with concurrent malignancies that are indolent or definitely treated may be enrolled.
- •Women who are pregnant or breastfeeding
