About this study

Official title: A Phase 1/2 Study of ARRY-520 in Patients With Advanced Myeloid Leukemia

This is a 2-phase study during which patients with select myeloid leukemias or advanced myelodysplastic syndrome (MDS), who have failed, refused or are not eligible for standard treatment, will receive investigational study drug ARRY-520.

The study has 3 parts. The first phase of the study, Phase 1, has 2 parts. In the first part of Phase 1, patients with select myeloid leukemias or advanced MDS will receive increasing doses of study drug on different schedules in order to achieve the highest dose possible that will not cause unacceptable side effects. Approximately 30 patients (per schedule) from the US will be enrolled in Part 1 (Completed). In the second part of Phase 1, patients with advanced MDS will receive the best dose of study drug and schedule determined from the first part of the study. Approximately 10 patients from the US will be enrolled in Part 2 (Completed).

In the third part of the study, Phase 2, patients with acute myeloid leukemia (AML) or advanced MDS will receive the best dose of study drug and schedule determined from the first part of the study and will be followed to see what side effects the study drug causes and to see what effectiveness it has, if any, in treating the cancer. Approximately 40 patients from the US will be enrolled in Part 3 (Withdrawn).

What is being measured

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

  1. Establish the maximum tolerated dose (MTD) of the study drug.

    Measured: Part 1

  2. Characterize the pharmacokinetics (PK) of the study drug.

    Measured: Part 1

  3. Characterize the safety profile of the study drug in terms of adverse events, dose limiting toxicity, clinical laboratory tests, weight, electrocardiograms and physical examinations.

    Measured: Part 1 and Part 2

  4. Assess the efficacy of the study drug in terms of incidence of complete remission (CR) and hematologic improvement (CRp).

    Measured: Part 3

Secondary outcomes (2)
  1. Assess the efficacy of the study drug in terms of incidence of CR and CRp.

    Measured: Part 1 and Part 2

  2. Characterize the safety profile of the study drug in terms of adverse events, dose limiting toxicity, clinical laboratory tests, weight, electrocardiograms and physical examinations.

    Measured: Part 3

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing ARRY-520, KSP(Eg5) inhibitor; intravenous in people with Advanced MDS and Acute Myeloid Leukemia, run by Pfizer at 2 sites 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 5 inclusion and 7 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 8 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Establish the maximum tolerated dose (MTD) of the study drug. (time frame: Part 1). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00637052, which also lists 1 linked publication.

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 8 Feb 2021.
