Brief Summary:
This randomized phase II trial studies how well ruxolitinib phosphate and dasatinib or nilotinib work in treating patients with chronic myeloid leukemia. Ruxolitinib, dasatinib, and nilotinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Condition or disease Intervention/treatment Phase
Chronic Phase Chronic Myelogenous Leukemia, BCR-ABL1 Positive Drug: Dasatinib Other: Laboratory Biomarker Analysis Drug: Nilotinib Drug: Ruxolitinib Phosphate Phase 2

Detailed Description:

PRIMARY OBJECTIVES:

I. To compare the rate of molecular response 4.5 (MR4.5) after 12 months of combination therapy with ruxolitinib phosphate (ruxolitinib) plus a tyrosine-kinase inhibitor (TKI) (dasatinib or nilotinib) versus a TKI alone, based on local polymerase chain reaction (PCR) testing to measure BCR-ABL transcripts in chronic phase chronic myelogenous leukemia (CML) patients with molecular evidence of disease.

SECONDARY OBJECTIVES:

I. To estimate the frequency and severity of toxicities of each regimen in this patient population.

II. To estimate progression free survival and overall survival of each regimen in this patient population.

TERTIARY OBJECTIVES:

I. To describe patterns of MR4.5 and molecular rate 4.0 (MR4.0) attainment and failure over the 3, 6, 9, and 12-month time points of each regimen in this patient population.

II. To evaluate drug compliance based on patient reported drug intake calendars in this patient population.

III. To describe the kinetics of response in this patient population (as measured by quantitative BCR-ABL/BCR ratio) in both arms over the 3, 6, 9, and 12-month time points.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive dasatinib orally (PO) daily or nilotinib PO twice daily (BID) on days 1-90. Treatment repeats every 90 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive ruxolitinib phosphate PO BID on days 1-90 and dasatinib PO daily or nilotinib PO BID on days 1-90. Treatment repeats every 90 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for up to 5 years.

    Will be estimated using the Kaplan-Meier method.

  3. Incidence of adverse events assessed by National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 [ Time Frame: Up to 5 years ]
  4. MR4.5 attainment and failure [ Time Frame: Up to 12 months ]
    Will be summarized descriptively

  5. Molecular rate 4.0 (MR 4.0) attainment and failure [ Time Frame: Up to 12 months ]
    Will be summarized descriptively

  6. Drug compliance [ Time Frame: Up to 5 years ]
    Will be summarized descriptively

  7. BCR-ABL/BCR analysis [ Time Frame: Up to 5 years ]
    Linear regression models will be used to assess associations between treatment arm and the quantitative endpoint.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients must have a diagnosis of chronic phase chronic myeloid leukemia without any history of progression to accelerated or blast phase CML; no new bone marrow aspiration and biopsy is needed to prove diagnosis prior to randomization; however, documentation stating the patient is in chronic phase is required
  • Patients must have detectable BCR-ABL transcripts measured by reverse transcriptase (RT)-PCR at a clinical laboratory improvement act (CLIA)-approved laboratory and reported on the international scale (IS) with a value of > 0.0032% IS and =< 1.0% IS within 21 days prior to randomization; the RT-PCR assay must have the sensitivity to detect a 4.5 log reduction in BCR-ABL transcripts from baseline (at least 0.0032% IS)
  • Patients must be receiving treatment with dasatinib (within the allowable dose range of 70-100 mg daily) or nilotinib (within the allowable dose range of 200-400 mg BID) as first or second line therapy for a minimum of 6 months prior to registration
  • Patients must not have received > 2 TKIs for treatment of CML (hydroxyurea prior to initiation of TKI is allowed)

    • Patients must have been on their current TKI for a minimum of 6 months prior to randomization
    • If dasatinib or nilotinib is second-line therapy, the reason for stopping first-line treatment must not have been resistance to prior treatment or failure to achieve an adequate response on their first-line TKI (e.g., the patient could have stopped due to intolerance to prior TKI)
  • Patients must have been receiving TKI treatment for CML for at least one year and no more than 10 years prior to randomization
  • Patients must be expected to remain on the same TKI for the next 12 months
  • Patients must not be receiving any other investigational agents

  • Patients known to be human immunodeficiency virus positive (HIV+) are eligible provided they meet all other eligibility criteria and have undetectable HIV viral loads
  • Specimens (peripheral blood) must be collected and submitted to a CLIA-approved laboratory, within 21 days prior to randomization; BCR-ABL transcripts must be measured using RT-PCR and results must be reported using the international scale; the RT-PCR assay must have the sensitivity to detect a 4.5 log reduction in BCR-ABL transcripts from baseline (at least 0.0032% IS)
  • Patients must be offered participation in submission of specimens for central BCR-ABL quantification; this submission is highly encouraged as an important protocol endpoint; with patient?s consent, specimens must be collected and submitted, within 21 days prior to randomization
  • Patients must be offered participation in specimen banking for future research; with patient?s consent, specimens must be submitted
