Primary Outcome Measures:
  • safety and tolerance (Maximum Tolerated Dose, Dose Limiting Toxicity) and efficacy (Response rate (CR or PR)) [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Time to response, response duration, overall survival, relapse-free survival, event-free survival and remission duration, Pharmacokinetics (PK) and Pharmacodynamics (PHDY) following PXD101 combination therapy [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]

Enrollment: 41
Study Start Date: August 2007
Study Completion Date: May 2009
Primary Completion Date: May 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm A

PXD101 administered as a 30-minute intravenous (IV) infusion of 1000 mg/m²/d for five consecutive days every 3 weeks.

Idarubicin administered on day 5 (first steps) or days 4 and 5 (later steps). Patients will be treated in a 21-day cycle for a minimum of 2 cycles and a maximum of 6 cycles (depending on cumulated idarubicin dose).

 Drug: PXD101
Other Name: Belinostat
Drug: idarubicin
Other Name: Zavedos
Experimental: Arm B
PXD101 administered by continuous intravenous infusion over 24-48 hours and idarubicin (in the later steps) added after the first 24 hours. The second cycle will start on day 15 but under observation of possible toxicity. Further cycles will be administered q 14 d for up to 6 cycles. The first dose steps will be carried out with PXD101 alone for safety reasons.
 Drug: PXD101
Other Name: Belinostat
Drug: idarubicin

Detailed Description:

This trial is an open-label, multi-centre, dose-escalation Phase I/II study to evaluate safety, explore efficacy, pharmacodynamics, and pharmacokinetics of the combination of PXD101 with idarubicin administered in two different schedules in patients with AML. The PXD101 plus idarubicin treatment will be repeated at suitable intervals (target is every 3 weeks for schedule A and every 2 weeks for schedule B) depending upon toxicities or disease progression. Safety and efficacy assessments will be performed at every cycle.

Schedule A uses PXD101 by 30 min infusion daily for 5 days every 3 weeks with escalating doses of idarubicin.

Schedule B uses escalating doses of continuous infusion (48h) of PXD101 alone or in combination with idarubicin.

In both regimens the trial may be expanded at the Maximum Tolerated Dose (MTD).

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria: (abbreviated)

  1. Signed consent

  2. AML patients:

  8. Precautions for female patients with reproductive potential as defined

Exclusion Criteria:

  1. Treatment with investigational agents within the last 4 weeks
  2. Prior treatment with HDAC (Histone deacetylases) inhibitors including valproic acid
  3. Prior anti-leukemic therapy (except hydroxyurea) within the last 3 weeks of trial dosing
  4. Co-existing active infection (including HIV) or any co-existing medical condition likely to interfere with trial procedures, including significant cardiovascular disease
  5. Altered mental status precluding understanding of the informed consent process and/or completion of the necessary study procedures.
  6. Concurrent second malignancy.
  7. History of hypersensitivity to idarubicin
  8. Cumulative idarubicin dose exceeding 100 mg/m², or a (with respect cardiotoxicity) corresponding dose of other anthracyclines
  9. LVEF (left ventricular ejection fraction) below normal range (< 45% )
