Brief Summary:

Phase 1 Part (Complete): Open-label, sequential dose escalation study of CPI-0610 in patients with previously treated Acute Leukemia, Myelodysplastic Syndrome, Myelodysplastic/Myeloproliferative Neoplasms, and Myelofibrosis.

Phase 2 Part: Open-label study of CPI-0610 with and without Ruxolitinib in patients with Myelofibrosis.

CPI-0610 is a small molecule inhibitor of bromodomain and extra-terminal (BET) proteins.

Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1/2 Study of CPI-0610, a Small Molecule Inhibitor of BET Proteins: Phase 1 (in Patients With Hematological Malignancies) and Phase 2 (Dose Expansion of CPI-0610 With and Without Ruxolitinib in Patients With Myelofibrosis)
Study Start Date : June 2014
Estimated Primary Completion Date : August 31, 2021
Estimated Study Completion Date : December 31, 2021


Arm Intervention/treatment
Experimental: Arm 1: Prior JAKi (JAK inhibitor) Monotherapy Arm
  • Cohort 1A: Open to patients with MF who are Transfusion Dependent (TD) and who have previously been treated with a JAKi and are intolerant, resistant, refractory or lost response to the JAKi, or are ineligible to be treated with a JAKi.(CPI-0610 alone)
  • Cohort 1B: Open to patients with MF who are not TD and who have previously been treated with a JAKi and are intolerant, resistant, refractory or lost response to the JAKi, or are ineligible to be treated with a JAKi. (CPI-0610 alone)
Drug: CPI-0610
Experimental: Arm 2: Prior JAKi Combination Arm
  • Cohort 2A: Open to patients with MF who are Transfusion Dependent (TD) and are currently taking ruxolitinib but have disease that is not being adequately controlled by ruxolitinib. (CPI-0610 + Ruxolitinib)
  • Cohort 2B: Open to patients with MF who are not TD and are currently taking ruxolitinib but have disease that is not being adequately controlled by ruxolitinib. (CPI-0610 + Ruxolitinib)
Drug: CPI-0610
Drug: Ruxolitinib
Experimental: Arm 3: JAKi Naïve Combination Arm
• Open to patients with MF who are anemic (i.e., Hemoglobin (Hgb) <10g/dL) and who have not previously received a JAKi. (CPI-0610 + Ruxolitinib)
Drug: CPI-0610
Drug: Ruxolitinib



Primary Outcome Measures :
  1. Phase 2 Part: Evaluate spleen response [ Time Frame: By imaging after 24 weeks ]
  2. Phase 2 Part: Evaluate the RBC (Red Blood Cell) transfusion independence rate [ Time Frame: Absence of RBC transfusion and no hemoglobin level below 8 g/dL in the prior 12 weeks ]

Secondary Outcome Measures :
  1. Phase 2 Part: Evaluate the duration of spleen response by imaging [ Time Frame: By palpation and imaging after 24 weeks ]
  2. Phase 2 Part: Evaluate response category rate [ Time Frame: Rate of response by IWG-MRT after 24 weeks ]
  3. Phase 2 Part: Evaluate the change in patient reported outcomes [ Time Frame: Changes from baseline in the total symptom score (MFSAF v4.0) and PGIC after 24 weeks ]
  4. Phase 2 Part: Evaluate the rate of RBC transfusion and the RBC transfusion dependence rate [ Time Frame: Average number of RBC units per subject-month ]
  5. Phase 2 Part: Pharmacokinetic parameters of CPI-0610 and ruxolitinib: AUC and Cmax [ Time Frame: Assessed during cycle 1 (first 21 days on study) ]
