Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Diagnosis of AML as defined by the World Health Organization (WHO) classification (Vardiman 2009)
  • Primary refractory AML (defined as a failure to achieve a CR or CRi after therapy with curative intent) or AML in first relapse
  • ECOG Performance status 0, 1 or 2
  • Age > 18 and < 70 years
  • For patients presenting with primary refractory AML, > 20% blasts on baseline bone marrow assessment
  • For patients presenting with relapsed AML, > 5% blasts on baseline bone marrow assessment

Exclusion Criteria:

  • An initial diagnosis of acute promyelocytic leukemia (as defined by French-American-British criteria (Bennett 1976))
  • Secondary AML, defined as AML evolving from antecedent hematological disorder or prior exposure to leukemogenic therapy or agent
  • Clinically active CNS leukemia
  • Previously received a total cumulative dose of cytarabine > 6g/m2 in the last 6 months
  • Previously received > 1 induction regimen (Defined as 1 or 2 cycles of a drug or a drug combination administered as remission induction therapy)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
To compare the response rate (CR + CRi) of AS1411 at 40 and 80mg/kg/day in combination with cytarabine therapy with the response rate (CR + CRi) of cytarabine therapy alone
Time Frame: Dec 2011
Dec 2011

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
To compare duration of remission, disease free survival and overall survival of AS1411 at 40 or 80mg/kg/day in combination with cytarabine therapy with that of cytarabine alone.
Time Frame: Dec 2011
Dec 2011
To compare the time to hematological recovery of AS1411 at 40 or 80mg/kg/day in combination with cytarabine therapy with that of cytarabine alone.
Time Frame: Dec 2011
Dec 2011
To compare the safety of AS1411 at 40 or 80mg/kg/day in combination with cytarabine therapy with that of cytarabine alone.
Time Frame: Dec 2011
