Brief Summary:
The purpose of this study is to determine if adding Ruxolitinib to a Tyrone Kinase Inhibitor (TKI), prior to a second attempt at stopping a TKI will lead to prolonged treatment free remission (TFR).

Condition or disease Intervention/treatment Phase
Chronic Phase Chronic Myeloid Leukemia Chronic Myeloid Leukemia, Chronic Phase Drug: Ruxolitinib Drug: BCR-ABL Tyrosine Kinase Inhibitor (TKI) Phase 2

Detailed Description:

All participants will have a confirmed diagnosis of chronic phase chronic myeloid leukemia (CML) and must have previously attempted to discontinue TKI therapy. All participants must be restarted on a TKI at the time of relapse in order to be eligible for this trial.

After completion of 12 cycles of combination therapy, eligible participants will remain in the TFR phase of the study for up to 36 months, and will have central polymerase chain reaction (PCR) testing during the first 24 months. Therefore, the total duration of the trial will be approximately 48 months (12 months on combination treatment phase + 36 months in the TFR phase).

Estimated Enrollment : 40 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Treatment Free Remission After Combination Therapy With Ruxolitinib Plus Tyrosine Kinase Inhibitors in Chronic Phase Chronic Myeloid Leukemia (CP-CML) Patients Who Relapsed After a Prior Attempt at TKI Discontinuation
Actual Study Start Date : November 15, 2019
Estimated Primary Completion Date : January 2021
Estimated Study Completion Date : January 2022


Arm Intervention/treatment
Experimental: Combination Therapy + Remission Phase

Combination therapy followed by treatment free remission (TFR) phase.

Combination Therapy: Ruxolitinib plus BCR-ABL Tyrosine Kinase Inhibitors (TKIs).

All eligible patients will begin ruxolitinib in combination with their BCR-ABL TKI on cycle 1 day 1 of the combination phase. They will continue combination therapy for a total of 12 cycles. Each cycle will be 28 days. At the end of 12 cycles ruxolitinib will be discontinued and any patient who has met the criteria for the treatment free remission (TFR) screening phase will enter into the TFR phase. Once in the TFR phase, participants will discontinue their BCR-ABL TKI and be monitored off treatment.

Drug: Ruxolitinib
Ruxolitinib: 15 mg by mouth (PO) twice a day (BID).
Other Name: Jakafi®

Drug: BCR-ABL Tyrosine Kinase Inhibitor (TKI)
The BCR-ABL TKIs that will be used include imatinib, dasatinib, nilotinib or bosutinib.
Other Name: TKI




Primary Outcome Measures :
  1. 12 Month Treatment Free Remission (TFR) [ Time Frame: 12 months ]
    TFR rate after completion of 12 cycles of combination therapy.


Secondary Outcome Measures :
  1. Adverse Events Possibly Related to Study Treatment [ Time Frame: Up to 30 days post treatment, approximately 13 months per participant ]
    Establish the adverse event profile of ruxolitinib in combination with BCR-ABL TKIs: Adverse Events (AEs) and Serious Adverse Events (SAEs) according to Common Terminology Criteria for Adverse Events (CTCAE) V5.0, that are possibly, probably, or definitely related to study treatment.


Other Outcome Measures:
  1. Incidence of Improved Scores in Health Related Quality of Life Questionnaire [ Time Frame: Up to 48 months ]
    Number of participants with an improved score in 2 or more categories of the questionnaire at the end of the TFR phase, when compared to the score for the same questions when completed at the end of 12 cycles of combination therapy.

Criteria

Inclusion Criteria:

  • Willing and able to give informed consent
  • Diagnosed with CML in chronic phase and have either the b3a2 (e14a2) or b2a2 (e13a2) variants that give rise to the p210 BCR-ABL protein.
  • Must have a documented history of attempting only one prior TKI discontinuation under the guidance of a treating physician
  • Must have met ALL the following criteria prior to first attempt to discontinue their TKI:

    • Stable molecular response (MR4; <0.01% IS) for > 2 years, as documented on at least 4 tests, performed at least 3 months apart
    • Treatment with one of the following FDA approved TKI; imatinib, dasatinib, nilotinib or bosutinib, at any dose for a minimum of 3 years prior to discontinuing TKIs
    • Has been on any number of TKIs, but has not been resistant to any TKI (changes made for intolerance are allowed)
  • Must have relapsed (defined as loss of major molecular response (MMR), RQ-PCR for BCR-ABL > 0.1% IS after first attempted discontinuation of TKI
  • After first failed TFR attempt, must have a minimum duration of 1 year on a TKI, and must plan to remain on this same TKI for a minimum of 12 months during the combination treatment phase
  • Current TKI must be the same as the TKI being taken prior to the initial TFR attempt (e.g., if patient is on imatinib prior to first TFR attempt, they should be on imatinib at time of enrollment on this study)
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-3
  • Must have a RQ-PCR for BCR-ABL less than 0.01% IS reported at time of study enrollment
  • Must adhere to all study contraception guidelines

Exclusion Criteria:

  • History of accelerated or blast phase CML
  • History of TKI resistance
  • A second malignancy requiring active treatment
  • Have previously received treatment with a JAK inhibitor.
  • Platelet count less than 100 × 10^9/L or an absolute neutrophil count of less than 1 × 10^9/L or Hemoglobin less than 8 g/dL
  • AST and ALT ≥ 3 times the institutional upper limit of normal (ULN)
  • Creatinine ≥ 2 times ULN
