3-AP and Cytarabine in Treating Patients With Hematologic Cancer
A Phase 1 study testing cytarabine and triapine in people with Leukemia and Myelodysplastic Syndromes, run by Vion Pharmaceuticals at 1 site in United States.
Trial summary
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… Read more about this study

About this study
Official title: 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.
Read the 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.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing cytarabine and triapine in people with Leukemia and Myelodysplastic Syndromes, run by Vion Pharmaceuticals at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Jul 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jul 2013.
