3-AP and Cytarabine in Treating Patients With Hematologic Cancer

July 17, 2013 updated by: Vion Pharmaceuticals

A Phase I Study of Triapine and Cytarabine in Patients With Hematologic Malignancies

RATIONALE: Drugs used in chemotherapy such as cytarabine use different ways to stop cancer cells from dividing so they stop growing or die. 3-AP may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth and may help cytarabine kill more cancer cells by making them more sensitive to the drug.

PURPOSE: Phase I trial to study the effectiveness of combining cytarabine with 3-AP in treating patients who have relapsed or refractory hematologic cancer.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

OBJECTIVES:

  • Determine the feasibility, tolerability, and toxic effects of 3-AP in combination with cytarabine in patients with hematologic malignancies.
  • Determine the maximum tolerated dose and phase II dose of cytarabine in this regimen in these patients.
  • Determine the biological effects of 3-AP and its interaction with cytarabine in these patients.

OUTLINE: This is a pilot, dose-escalation study of cytarabine.

Patients receive 3-AP IV over 6 hours followed by cytarabine IV over 18 hours on days 1-5. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients achieving a response may receive an additional course as consolidation therapy.

Cohorts of 3-6 patients receive escalating doses of cytarabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, an additional 10 patients receive treatment at that dose.

PROJECTED ACCRUAL: Approximately 20-25 patients will be accrued for this study.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers
