Brief Summary:
This phase I/II studies the safety and efficacy of ruxolitinib in combination with liposomal formulation of cytarabine and daunorubicin (CPX-351) for treatment of secondary acute myelogenous leukemia (AML) transformed from myeloproliferative neoplasms (MPNs). The phase I portion of the study will establish the maximum tolerated dose (MTD) for ruxolitinib in combination with a fixed dose of CPX-351. The modified Toxicity Probability Interval (mTPI) design will be used to determine the optimal dose of ruxolitinib in combination with CPX-351. Once the MTD is established and phase I objectives completed, the study will open for enrollment in the phase II portion of the trial. The phase II portion of the trial will assess the efficacy of the ruxolitinib and CPX-351 combination. Prior publications highlight the important role of the janus kinase inhibitor, ruxolitinib in the treatment of MPNs and its preliminary efficacy in combination with hypomethylating agents for the treatment of secondary AML.

Acute Myeloid Leukemia Acute Lymphoblastic Leukemia Drug: Ruxolitinib Drug: CPX-351 Phase 1 Phase 2

Detailed Description:

PRIMARY OBJECTIVES:

I. Phase I: To evaluate the MTD of ruxolitinib in combination with CPX-351 for treatment of post-MPN AML.

II. Phase II. To evaluate the rate of composite complete remission in patients with secondary AML transformed from MPNs (PV, ET and MF) following treatment with the combination of Ruxolitinib and CPX-351 (8 weeks at end of induction or re-induction). The composite complete remission (CRc) includes complete remission (morphologic CR) and complete remission with incomplete count recovery (CRi).

SECONDARY OBJECTIVES:

I. Phase I: To evaluate the safety and tolerability of ruxolitinib in combination with CPX-351 for treatment of post-MPN AML II. Phase II: Assess survival outcomes and proportion of patients receiving transplant associated with ruxolitinib in combination with CPX-351.

III. Phase II: Assess safety and incidence of adverse events as assessed by CTCAE v5.0.

EXPLORATORY OBJECTIVES:

I. Phase II: Assess the proportion of treated (completion of induction or re-induction) participants with sub-clinical levels of AML (i.e., minimal residual disease, MRD) as measured by flow cytometry and/or next generation sequencing of known mutations (e.g., JAK-2, CALR and other disease-specific mutations) at the end of 6 months. Cytogenetic and molecular remission will be measured.

OUTLINE:

Phase I. Eligible participants will first receive induction therapy consisting of intravenous CPX-351 (65 u/m2) administered on day 1, 3, and 5, which will be followed by a 23 day course of ruxolitinib (days 6 to 28) that will be given at a starting dose of 20 mg BID and will increase according to the mTPI dose escalation/de-escalation rule (up to the maximum dose of 25 mg BID). A bone marrow aspirate/biopsy will be performed between D14-D22 to assess disease status and possible need for re-induction. A recovery bone marrow aspirate/biopsy to assess response to induction will be performed between D35-D42 or when ANC>500 and platelet count > 50,000 per microliter; depend on which events occurs first. An enrollment of up to 24 participants is planned for the phase I portion of this study.

Phase II. Once the MTD is established and phase I objectives completed, the study will open for enrollment in the phase II portion of the trial. The phase II portion of the trial will assess the efficacy of the ruxolitinib and CPX-351 combination by evaluating the rate of composite complete remission in participants using a Simon's two-stage minimax design. Enrollment in phase II is planned for a total of 26 participants. The combination treatment regimen will be the same as described for phase I except that ruxolitinib dose will also be fixed per the recommended phase 2 dose (RP2D)(i.e., established MTD).

Participants are eligible to proceed to allogeneic hematopoietic stem cell transplantation (allo-HSCT) at any time after achieving complete remission (CR/CRi) if they have a suitable donor. In this case, participants will come off treatment and be followed for disease status and survival outcomes, including peri-transplant data

Arm Intervention/treatment
Experimental: Ruxolitinib in combination with CPX-351
Phase I, participants start with induction therapy consisting of intravenous CPX-351 (65 u/m2) administered on day 1, 3, and 5, which will be followed by a 23 day course of ruxolitinib (days 6 to 28) that will be given at a starting dose of 20 mg BID and will increase according dose escalation/de-escalation rule. A bone marrow aspirate/biopsy will be performed between day 14-22 and potentially again on day 35-42 to assess disease status and possible need for re-induction. Those with CR/CRi after induction will receive 1-2 cycles of consolidation therapy. Participants who completed consolidation therapy with CR/CRi and have not undergone allo-HSCT will complete 12 months of maintenance therapy with ruxolitinib according to established dose derived during phase I. For Phase II, drug regimen, schedule and assessments will remain the same as phase I except that ruxolitinib will be administered at the MTD or recommended phase II dose (RP2D).

Primary Outcome Measures :
  1. Dose Limiting Toxicity (DLT) of ruxolitinib given in combination with CPX-351. [ Time Frame: Day 1 to end of first induction (Day 28) ]
    DLT of ruxolitinib given in combination with CPX-351. DLT is defined as treatment related ≥ Grade 3 non-hematological or ≥ Grade 4 hematological toxicity.

  2. Rate of composite complete remission (CRc), morphologic CR, and CRi [ Time Frame: Day 1 to 8 weeks post induction or re-induction ]
    A Simon's two-stage minimax design will be used. The null hypothesis that the true composite complete remission rate is 0.35 (based on historical data) will be tested against a one-sided alternative of a composite complete remission rate of 0.60 with the combination of CPX-351 and ruxolitinib. In the first stage, 18 patients will be accrued. If there are 6 or fewer composite complete remissions in these 18 patients by the end of induction or re-induction therapy, the study will be stopped. Otherwise, 8 additional patients will be accrued for a total of 26 patients. The null hypothesis will be rejected and the combination therapy deemed promising if 14 or more composite complete remissions are observed during induction or consolidation cycles among the 26 patients.


Secondary Outcome Measures :
  1. Incidence of adverse events as assessed by CTCAE version 4.03 [ Time Frame: Up to 30 days after last on-study dose ]
    The incidence of treatment-related toxicity and the exact confidence interval will be measured. Each toxicity event will be tabulated and summarized by severity and major organ site according to the CTCAE v4.03.

  2. Progression Free Survival (PFS) [ Time Frame: 1 year post treatment ]
    Time-to-event analysis (e.g., Kaplan-Meier and cumulative incidence curves) will be used to evaluate event-free and overall survival. A point estimate and confidence interval will be computed for the proportion of participants who undergo an allo-SCT.

  3. Overall Survival (OS) [ Time Frame: 1 year post treatment ]
    Time-to-event analysis (e.g., Kaplan-Meier and cumulative incidence curves) will be used to evaluate overall survival.

  4. Proportion of patients proceeding to transplant [ Time Frame: Date of enrollment to time of transplant or end of follow-up (if no transplant), up to 2 years ]
    A point estimate and 95% confidence interval will be computed for the proportion of participants who undergo an allo-SCT (stem cell transplant).


Other Outcome Measures:
  1. Proportion of participants with minimal residual disease (MRD) at end of induction. [ Time Frame: End of induction, up to 2 months on study ]
    Detection of MRD will be achieved by either multi-color flow cytometry (MFC) or next-generation sequencing (NGS) technology and examined using regression based analysis (e.g., logistic regression and Cox regression).

  2. Proportion of participants with minimal residual disease (MRD) at end of re-induction. [ Time Frame: End of re-induction, up to 4 months on study ]
    Detection of MRD will be achieved by either multi-color flow cytometry (MFC) or next-generation sequencing (NGS) technology and examined using regression based analysis (e.g., logistic regression and Cox regression).

  3. Proportion of participants with minimal residual disease (MRD) at end of maintenance. [ Time Frame: Up to 12 months on study ]
    Detection of MRD will be achieved by either multi-color flow cytometry (MFC) or next-generation sequencing (NGS) technology and examined using regression based analysis (e.g., logistic regression and Cox regression).

  4. Frequency of each mutation (single nucleotide polymorphism (SNP)) [ Time Frame: End of induction or re-induction, up to 6 months on study ]
