Study Description
Brief Summary:
Open-label, sequential dose escalation and expansion study of CPI-0610 in patients with previously treated Acute Leukemia, Myelodysplastic Syndrome, Myelodysplastic/Myeloproliferative Neoplasms, and Myelofribrosis. CPI-0610 is a small molecule inhibitor of bromodomain and extra-terminal (BET) proteins.

Condition or disease Intervention/treatment Phase
Leukemia, Myelocytic, Acute Myelodysplastic Syndrome (MDS) Myelodysplastic/Myeloproliferative Neoplasm, Unclassifiable Myelofibrosis Drug: CPI-0610 Phase 1

Study Design

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 75 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1 Study of CPI-0610, a Small Molecule Inhibitor of BET (Bromodomain and Extra-terminal) Proteins, in Patients With Acute Leukemia, Myelodysplastic Syndrome, Myelodysplastic/Myeloproliferative Neoplasms, and Myelofibrosis
Study Start Date : June 2014
Estimated Primary Completion Date : October 2018
Estimated Study Completion Date : January 2019

Arms and Interventions

Arm Intervention/treatment
Experimental: CPI-0610 Drug: CPI-0610

Outcome Measures

Primary Outcome Measures :
  1. Frequency of dose-limiting toxicities (DLTs) associated with CPI-0610 administration during the first cycle (first 21 days) of treatment [ Time Frame: DLTs asessed during Cycle 1 (first 21 days on study) ]

Secondary Outcome Measures :
  1. Safety and tolerability of CPI-0610 as assessed by: frequency of adverse events and serious adverse events; changes in hematology and clinical chemistry values; changes in physical examination, vital signs, electrocardiogram, ECHO and ECOG score [ Time Frame: Assessed from Day 1 of Cycle 1 through 30 days after patient's last dose of study drug ]
  2. Pharmacokinetic parameters of CPI-0610: AUC(0-t), AUC(0-inf), AUCtau,ss, Tmax, Cmax, Ctrough, T1/2, Vd/F, CL/F [ Time Frame: Assessed during cycle 1 (first 21 days on study); and on cycle 2, day 1 ]
  3. Pharmacodynamic effects of CPI-0610: Changes in the expression of MYC and other genes in leukemic cells; changes in cellular proliferation and in the extent of apoptosis [ Time Frame: Assessed during cycle 1 (first 21 days on study); and on cycle 2, day 1 ]
    This is a composite outcome measure

  4. Changes in the expression of a set of genes in peripheral blood mononuclear cells (PBMCs) that are sensitive to BET inhibition [ Time Frame: Assessed during cycle 1 (first 21 days on study) ]
  5. Anti-leukemia, anti-myelodysplastic syndrome, anti-myelodysplastic/myeloproliferative neoplasm, and anti-myelofibrosis activity associated with CPI-0610 treatment [ Time Frame: Assessed after every 2 cycles of treatment for the first 6 cycles, and after every 4 cycles thereafter; assessed up to approximately 12 months ]
    Leukemia, MDS and MDS/MPN will be assessed using the 2013 NCCN criteria for ALL, the 2003 Cheson criteria for AML, and the 2006 modified International Working Group (IWG) criteria for MDS, MDS/MPN, and MF,

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

Inclusion Criteria:

  • Adult (aged ≥ 18 years)
  • Histologically or cytologically confirmed diagnosis of one of the following hematologic malignancies: AML, ALL, acute undifferentiated or biphenotypic leukemia, CML in blast crisis, MDS or MDS/MPN, and Myelofribrosis
  • ECOG performance status ≤2.
  • Adequate hematological, renal, hepatic, and coagulation laboratory assessments
  • Patients must give written informed consent to participate in this study before the performance of any study-related procedure.

Exclusion Criteria:

  • Newly diagnosed acute leukemia that has not been treated with a standard induction chemotherapeutic regimen or with another anti-leukemic agent
  • Relapsed or refractory acute leukemia, where additional induction chemotherapy is considered to be of potential clinical benefit
  • Acute leukemia in relapse less than 6 months following allogeneic stem cell transplantation
  • CML in blast crisis and previously treated with only one bcr-abl TKI
  • Very low or low risk MDS without previous treatment
  • Central nervous system (CNS) (e.g., leptomeningeal) involvement by leukemia
  • Current infection with HIV, Hepatitis B or Hepatitis C
  • Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of CPI-0610, including any unresolved nausea, vomiting, or diarrhea that is CTCAE grade >1
  • Impaired cardiac function or clinically significant cardiac diseases, including any of the following:

    • Acute myocardial infarction or angina pectoris ≤ 6 months prior to starting study drug
    • Serum cardiac troponin (cTn) level ≥ 99% percentile of the upper reference limit
    • QTcF > 470 msec on the screening ECG
    • Left ventricular ejection fraction (LVEF) < 50%
  • Uncontrolled cardiac arrhythmia (patients with rate-controlled atrial fibrillation are not excluded.)
  • Any other concurrent severe and/or uncontrolled concomitant medical condition that could compromise participation in the study (e.g., clinically significant pulmonary disease, clinically significant neurological disorder, active or uncontrolled infection)
  • Systemic anti-cancer treatment with a small molecule therapeutic other than hydroxyurea or radiotherapy less than 2 weeks before the first dose of CPI-0610
  • Administration of a therapeutic antibody less than 4 weeks before the first dose of CPI-0610. A minimum 2-week period between the last treatment with a therapeutic antibody and the first dose of CPI-0610 may be permitted in patients with rapidly progressive disease, following discussion with the medical monitor
  • Treatment with an investigational small molecule less than 2 weeks before the first dose of CPI-0610. In addition, the first dose of CPI-0610 should not occur before a period equal to or greater than 5 half-lives of the small molecule investigational agent has elapsed
  • Treatment with medications that are known to be strong inhibitors or inducers of CYP450 enzymes
  • Treatment with medications that are known to carry a risk of Torsades de Pointes
  • Immunosuppressive treatment that cannot be discontinued both prior to study entry and for the duration of the study. Oral prednisone at a dose of 10 mg or less per day is allowed, as are other oral corticosteroids given at glucocorticoid-equivalent doses. Topical, nasal and inhaled corticosteroids are also allowed
  • Pregnant or lactating women
  • Women of child-bearing potential and men with reproductive potential, if they are unwilling to use adequate contraception while on study therapy and for 3 months thereafter
  • Patients unwilling or unable to comply with the study protocol
