  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • APML diagnosis based upon morphological, histochemical, and/or flow cytometric criteria, confirmed upon review by a central, study-designated hematologic pathologist;
  • OR
  • any relapsed acute leukemia bearing a t(15:17) translocation or variant APML translocations involving the retinoic acid receptor alpha gene on chromosome 15q22, based on cytogenetics or PCR.
  • disease in first or subsequent relapse, following standard induction and consolidation chemotherapy (with all-trans retinoic acid) and/or allogeneic bone marrow/stem cell transplantation;
  • OR
  • failure to achieve initial complete remission with ATRA and standard chemotherapy.

Who cannot join

  • Availability of a fully HLA-matched sibling donor for patients otherwise felt to be candidates for allogeneic bone marrow/stem cell transplantation; patients with only a partially HLA-matched sibling or matched unrelated donor will remain eligible for study entry.

Otherwise, there are no rigid exclusion criteria based upon age, performance status, or co-morbidity. Decisions regarding enrollment of patients for whom these factors may be relevant will be individualized and left to the discretion of the investigators.

About this study

Official title: A Phase I/II Trial of Infusional Arsenic Trioxide for Relapsed Acute Promyelocytic Leukemia

The purpose of this study is to evaluate both the efficacy and toxicity of infusional arsenic trioxide in the treatment of patients with relapsed or refractory acute promyelocytic leukemia (APML). In addition, correlation between pharmacokinetic data and both therapeutic response and therapy-related toxicities will be sought.

Read the detailed description

OUTLINE: This is a dose-escalation study.

Patients receive arsenic trioxide IV over 2 hours daily for 28 days followed by a 14 day rest period. Patients may receive up to 3 courses of treatment.

Dose escalation continues in cohorts of 3-6 patients until the maximum tolerated dose (MTD) or minimum effective dose (MED) is determined. The MTD is defined as the dose preceding that at which 2 or more patients experience dose limiting toxicity. The MED is defined as the dose at which 4 of 6 patients achieve a complete cytogenetic or molecular response. After the MTD or MED is determined, an additional 20 patients are enrolled at this dose level.

Patients are followed monthly for 6 months and every three months for an additional 1.5 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) or minimum effective dose (MED)

    Measured: 6 weeks

  2. Efficacy (response and survival) at the MTD - Phase 2 only

    Measured: 18 weeks

Secondary outcomes (3)
  1. Acute and chronic toxicities

    Measured: 18 weeks

  2. Evaluation of the pharmacokinetics and their correlation with toxicities and response

    Measured: 18 weeks

  3. Evaluation of PML/RARA and PML protein redistribution and degradation following treatment and their correlation with response

    Measured: 18 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing arsenic trioxide in people with Leukemia, run by Washington University School of Medicine 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?

The sponsor lists 6 inclusion and 4 exclusion criteria. 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 12 Apr 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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.

What does the primary outcome measure?

Maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) or minimum effective dose (MED) (time frame: 6 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

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 12 Apr 2013.
