A Study of Clofarabine for Older Patients With Newly Diagnosed Acute Myelogenous Leukemia (AML) (CLASSIC II)
A Phase II Study of Single Agent Clofarabine in Previously Untreated Older Adult Patients With Acute Myelogenous Leukemia (AML) for Whom Standard Induction Chemotherapy is Unlikely to be of Benefit
Clolar (clofarabine injection) is approved by the Food and Drug Administration (FDA) for the treatment of pediatric patients 1 to 21 years old with relapsed acute lymphoblastic leukemia (ALL) who have had at least 2 prior treatment regimens.
This study will evaluate the efficacy of clofarabine in elderly patients with acute myelogenous leukemia (AML) who are unlikely to benefit from treatment with intensive chemotherapy regimens (cytarabine and anthracycline based regimens) used in younger patients with AML.

- Ongoing uncontrolled systemic infection
- Diagnosis of another malignancy, unless the patient has been disease-free for at least 5 years following the completion of curative intent therapy with the following exceptions: Patients with treated non-melanoma skin cancer, in-situ carcinoma or cervical intraepithelial neoplasia regardless of disease-free duration are eligible for this study if definitive treatment for the condition has been completed; Patients with organ-confined prostate cancer with no evidence of recurrent or progressive disease based on PSA value are eligible for this study if hormonal therapy has been initiated or a radical prostatectomy has been performed
- Clinical evidence of central nervous system (CNS) involvement
- Severe concurrent medical condition or psychiatric disorder that would preclude study participation
- Positive human immunodeficiency virus (HIV) test

Experimentální: Clofarabine
Participants received an induction cycle of clofarabine 30 mg/m^2/day intravenous infusion for 5 consecutive days.
Participants could then receive up to 5 additional cycles, repeated minimally every 28 days, of clofarabine 20 mg/m^2/day intravenous infusion for 5 consecutive days.
|
Induction cycle 1: cycle 1 of clofarabine 30 mg/m^2/day as a 1-hour intravenous infusion for 5 consecutive days. Reinduction (cycle 2) and/or Consolidation cycles (cycles 2-6): cycles repeated minimally every 28 days, of clofarabine 20 mg/m^2/day as a 1-hour intravenous infusion for 5 consecutive days.

Percentage of Participants Achieving Overall Remission (OR) After No More Than Two Cycles (Approximately Month 2)
Časové okno: approximately Month 2
|
Best response was assessed by the Independent Response Review Panel(IRRP) after two cycles of treatment.
Overall remission(OR) is the sum of complete remission(CR) and complete remission in the absence of platelet recovery(CRp).
CR includes normal values for peripheral blood cell counts (absolute neutrophil and platelet) and leukemic blast cells from bone marrow biopsy or aspirate, and absence of extramedullary disease.
Partial remission(PR) includes recovery of peripheral blood cells with improved but still abnormal values in leukemic blast cells.

DOR was defined as the number of days from achievement of OR as assessed by the Independent Response Review Panel (IRRP) until IRRP-determined disease recurrence or death (any cause), plus 1 day.
Participants who initiated alternative antileukemic treatment while in remission were censored on the date the therapy was initiated or on the date of last follow-up.

Overall Participant Counts Summarizing Adverse Events (AEs) During the Treatment and Follow-up Periods
Časové okno: Up to 2 years
|
Participants with AEs that occurred during the treatment and follow-up periods. AEs were classified according to severity (graded using National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE] version 3.0) and relationship to study drug. Treatment emergent is defined as any event that either first presents after baseline or worsens in severity after baseline. NCI Common Terminology Criteria for Severity: Grade 1= Mild AE, Grade 2= Moderate AE, Grade 3= Severe AE, Grade 4= Life-threatening or disabling AE, Grade 5= Death related to AE |
