A Study of Clofarabine for Older Patients With Newly Diagnosed Acute Myelogenous Leukemia (AML) (CLASSIC II)

17. mars 2014 oppdatert av: Genzyme, a Sanofi Company

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

Tiltaksbeskrivelse
Tidsramme
Percentage of Participants Achieving Overall Remission (OR) After No More Than Two Cycles (Approximately Month 2)
Tidsramme: 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.
approximately Month 2

Tiltaksbeskrivelse
Tidsramme
Kaplan Meier Estimate for Duration of Remission (DOR)
Tidsramme: Up to 2 years
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.
Up to 2 years
Kaplan Meier Estimate for Disease-free Survival (DFS)
Tidsramme: Up to 2 years
DFS was defined as the number of days from achievement of IRRP-determined overall response until IRRP-determined disease recurrence or death (any cause), regardless of intervening alternative antileukemic treatment, plus 1 day.
Up to 2 years
Kaplan Meier Estimates for Overall Survival (OS)
Tidsramme: Up to 2 years
OS was defined as the number of days from first dose of clofarabine until death for all participants, plus 1 day.
Up to 2 years
Overall Participant Counts Summarizing Adverse Events (AEs) During the Treatment and Follow-up Periods
Tidsramme: 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
Up to 2 years
Percentage of Participants Who Died Within Thirty Days of Treatment (30-day Mortality Rate)
Tidsramme: up to Day 30
Percentage of participants who died within 30 days of the first dose of study drug, regardless of cause.
up to Day 30
