Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 15 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Diagnosis of chronic myeloid leukemia (CML) in chronic phase; clonal cytogenetic evolution alone does not exclude patients
  • Patients in whom a Philadelphia chromosome [t(9;22)] or a variant translocation is not detectable by cytogenetic studies are eligible if they meet one of the following criteria:
  • Polymerase chain reaction (PCR) positive fusion transcripts for BCR/ABL;
  • BCR/ABL translocation present by fluorescence in situ hybridization (FISH)
  • Patients must have received prior therapy with imatinib mesylate (>= 400 mg/day for > 8 weeks without a complete hematologic response or >= 400 mg/day for > 6 months without a major cytogenetic response) and must not have evidence of progressive disease (accelerated or blast phases)
  • Patients must have received a stable dose of imatinib mesylate >= 600 mg/day for at least 4 weeks without > grade 1 toxicities; the first six patients enrolled will be restricted to receiving an imatinib mesylate dose of 600 mg/day while on study
Show all 19Show fewer
  • No prior therapy with hydroxyurea, cytarabine, interferon, anagrelide, homoharringtonine, or any other investigational agent within 4 weeks of study enrollment
  • Patients may not have received other antineoplastic medications (e.g., busulfan)
  • No prior stem cell transplantation
  • Patients must not require oral anticoagulant therapy
  • Non-pregnant and non-nursing; treatment under this protocol would expose an unborn child to significant risks. Women and men of reproductive potential should agree to use an effective means of birth control throughout the duration of protocol treatment and for at least three months after the last dose of imatinib mesylate
  • No other serious illnesses which would limit survival to < 2 years, or a psychiatric condition which would prevent compliance with treatment or informed consent
  • No uncontrolled cardiovascular disease, diabetes, pulmonary disease, or infection, which in the opinion of the treating physician, would make this protocol treatment unreasonably hazardous for the patient
  • Patients with a "currently active" second malignancy other than non-melanoma skin cancers are not eligible; patients are not considered to have a "currently active" malignancy if they have completed therapy and are considered by their physician to be at less than 30% risk of relapse within one year
  • Bilirubin =< 2 mg/dL
  • Creatinine =< 2 mg/dL
  • AST =< 1.5 x Upper Limit of Normal
  • PTT =< 1.5 x Upper limit of Normal
  • BHCG Negative (if patient of childbearing potential)

About this study

Official title: A PHASE II STUDY OF G3139 (GENASENSE™, NSC # 683428 IND # 58842) + IMATINIB MESYLATE (GLEEVEC®, STI571) IN PATIENTS WITH IMATINIB-RESISTANT CHRONIC MYELOID LEUKEMIA

Phase II trial to study the effectiveness of combining oblimersen with imatinib mesylate in treating patients who have chronic myelogenous leukemia that has not responded to previous treatment with imatinib mesylate. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. Oblimersen may help imatinib mesylate kill more cancer cells by making cancer cells more sensitive to the drug.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To estimate the cytogenetic response rate of patients with CML who have had less than a complete hematologic response or less than major cytogenetic response to imatinib mesylate and who have been treated after two cycles of imatinib mesylate + G3139.

SECONDARY OBJECTIVES:

  1. To estimate the hematologic, cytogenetic and molecular response rate and duration in patients diagnosed with CML who have been treated after two and four cycles of imatinib mesylate + G3139.

II. To estimate the toxicity of these two drugs given in combination in a cooperative group setting.

OUTLINE:

Patients receive oblimersen IV continuously on days 1-10 and oral imatinib mesylate once or twice daily. Treatment repeats every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. Patients without a hematologic response after 2 courses go off study. Patients with complete or partial response after 4 courses may continue to receive oral imatinib mesylate daily.

Patients in cohort 2 receive an escalated dose of oblimersen; if well tolerated, subsequent cohorts receive oblimersen at the higher dose with the original dose of imatinib mesylate. If oblimersen is not well tolerated in cohort 2, subsequent cohorts receive the original dose of oblimersen with an escalated dose of imatinib mesylate. The first 6 patients accrued continue to receive the original dose (dose taken prior to study) of imatinib mesylate throughout the study.

Patients are followed monthly for 3 months and then every 3 months for 5 years.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing oblimersen sodium, imatinib mesylate and laboratory biomarker analysis in people with Chronic Myelogenous Leukemia, BCR-ABL1 Positive and Chronic Phase Chronic Myelogenous Leukemia, run by National Cancer Institute (NCI) 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 19 inclusion and 0 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 4 Jun 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 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?

Cytogenetic response rate in bone marrow (time frame: 42 days). 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 4 Jun 2013.
