About this study

Official title: A Multicenter Phase Ib Trial to Determine Whether a Gene Expression Signature Changes in Response to Treatment With Bcr-Abl Inhibitors in Patients With Blast Phase Philadelphia Chromosome Positive Chronic Myelogenous Leukemia or Philadelphia Chromosome Positive Acute Lymphocytic Leukemia

This study will evaluate a gene expression signature (Growth Factor Signature [GFS]) as a biomarker for response/resistance to BRC-ABL oncogene inhibitors.

Being tested
Comparator: Biomarker evaluation
Medical subject headings
Leukemia, Myelogenous, Chronic, BCR-ABL Positive, Precursor Cell Lymphoblastic Leukemia-Lymphoma

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Comparator: Biomarker evaluationOther

    Patients on standard of care treatment will have blood drawn to evaluate biomarker changes in response to treatment with BCR-ABL inhibitors over a ~3.5 month period.

    Part I will enroll patients who are beginning treatment with imatinib (recommended dose 400 mg every day [qd]), dasatinib (recommended dose 70 mg twice a day [bid]), or nilotinib (recommended dose 400 mg bid).

    Part II will enroll patients who are changing from imatinib therapy to either dasatinib or nilotinib. A decision to initiate Part II will be made based on analysis of the results of Part I.

What is being measured

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

  1. Growth Factor Signature (GFS) Variability at Baseline

    The GFS was measured by microarray analysis using the entire 101 gene signature. The GFS is quantified as the change in gene expression between two separate samples collected from the same patient. The signature has 101 genes in two oppositely regulated arms, which are pre-specified. The expression of genes in the UP arm goes up with increasing pathway activity, and the expression of genes in the DOWN arm goes down with increasing pathway activity.

    The GFS variability was represented by the GFS change between two baseline samples (Mean GFS Fold Ratio [Screening to Day 1 Predose]).

    Measured: Screening to Day 1 Predose

  2. Growth Factor Signature (GFS) Change From Baseline Measured by Time Weighted Average (TWA) for Days 1 to 22

    The GFS was measured by microarray analysis using the entire 101 gene signature.

    The TWA is the area under the curve (AUC) divided by the time interval (for this study it was the AUC of gene-expression divided by Days 1 to 22).

    Participants with blast phase Ph+ CML or Ph+ ALL were measured for change in the GFS post-treatment when treated with imatinib, dasatinib, or nilotinib, using Microarray. Change was represented as the GFS Fold Ratio of TWA for Days 1 to 22 to Baseline.

    Measured: Baseline to 22 Days After Initiation of Therapy

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Comparator: Biomarker evaluation in people with Blast Phase Philadelphia Chromosomes Positive (Ph+) Chronic Myelogenous Leukemia (CML) and Philadelphia Chromosome Positive (Ph+) Acute Lymphocytic Leukemia (ALL), run by Merck Sharp & Dohme LLC.

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 11 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: stopped early, as of the sponsor's last update on 30 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 10 Oct 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Growth Factor Signature (GFS) Variability at Baseline (time frame: Screening to Day 1 Predose). 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 30 Sep 2015.
