Vincristine Sulfate Liposome in Treating Patients With Relapsed or Refractory Acute Myeloid Leukemia
An Open Label, Phase II Study of the Feasibility and Efficacy of Vincristine Sulfate Liposome Injection in Patients With Relapsed or Refractory Acute Myeloid Leukemia (AML)

Conditions
Intervention / Treatment
Detailed Description
PRIMARY OBJECTIVES:
I. To determine the feasibility of administering vincristine sulfate liposome injection (VSLI) to relapsed or refractory acute myeloid leukemia (AML) patients having failed, refused or not a candidate for at least one chemotherapy salvage regimen.
II. To observe the hematologic improvement-rate of VSLI in this patient population.
SECONDARY OBJECTIVES:
I. To observe the overall survival of patients treated with VSLI. II. To observe the response rate (complete remission [CR], complete remission with incomplete count recovery [CRi], partial response [PR], and morphologic leukemia free state [MLFS]) of VSLI in this patient population.
OUTLINE:
Patients receive vincristine sulfate liposome via injection on days 1, 8, 15, and 22. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for up to 6 months.

- Patients must be ineligible for, refused or having failed at least one previous salvage regimen
- Eastern Cooperative Oncology Group (ECOG) performance status of =< 3
- Women of child-bearing potential (i.e., women who are pre-menopausal or not surgically sterile) must use accepted contraceptive methods (abstinence, intrauterine device [IUD], oral contraceptive or double barrier device), and must have a negative serum or urine pregnancy test within 1 week prior to treatment initiation
- Fertile men must practice effective contraceptive methods during the study period, unless documentation of infertility exists
- Mentally competent, ability to understand and willingness to sign the informed consent form

- No condition or abnormality which may, in the opinion of the investigator, compromise the safety of the patient
- No unwillingness or inability to follow protocol requirements
- No evidence of ongoing, uncontrolled infection
- No requirement for immediate palliative treatment of any kind including surgery
- No option for immediate bone marrow transplant unless patient refuses this therapy
- Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase (SGOT) =< 3 x upper normal limit (UNL), alanine aminotransferase (ALT)/serum glutamate pyruvate transaminase (SGPT) =< 3 x UNL
- Bilirubin =< 3 x UNL
- Glomerular filtration rate (GFR) > 50 ml/min/1.72 m^2 or creatinine < 2 g/dL
Exclusion Criteria:

- Fertile men unwilling to practice contraceptive methods during the study period
- Any condition or abnormality which may, in the opinion of the investigator, compromise the safety of patients
- Unwilling or unable to follow protocol requirements
- Evidence of ongoing, uncontrolled infection
- Patients with known human immunodeficiency virus (HIV) infection
- Requirement for immediate palliative treatment of any kind including surgery
- Evidence of inadequate hepatic function (aspartate aminotransferase [AST/SGOT] =< 3 x upper normal limit [UNL], alanine aminotransferase [ALT/SGPT] =< 3 x UNL [=< 5 x ULN if liver metastases present], bilirubin =< 1.5 x UNL)

Response Rate (CR, CRi, PR, and MLFS)
Time Frame: Up to 6 months after completion of study treatment
|
Confidence intervals will be calculated around the estimates of the response rate (CR, CRi, PR, and MLFS) of VSLI. Assuming a response rate of 0.1, with 39 participants, 95 percent confidence intervals with a 0.09 margin of error (0.01, 0.19) or a margin of error of 0.16 around a response rate of 0.5 will be created. (Complete remission (CR) bone marrow blasts <5%, absence of blasts with Auer rods; absence of extramedullary disease, absolute neutrophil count >1,000, platelet count >100,000, independence of red cell transfusions; Complete remission with incomplete recovery (CRi) all complete remission except for residual neutropenia or thrombocytopenia; partial remission (PR), decrease of bone marrow blast to 5-25%, decrease of pre-treatment bone marrow blast by at least 50%; morphologic leukemia-free state (MLFS) Bone marrow blasts <5%, absence of Aeur rods, absence of extramedullary disease, no hematologic recovery required). |

Overall Survival
