Trial of PXD101 (Belinostat) in Combination With Idarubicin to Treat AML Not Suitable for Standard Intensive Therapy
A Phase I/II Clinical Trial of PXD101 in Combination With Idarubicin in Patients With AML Not Suitable for Standard Intensive Therapy

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).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
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). |
Other Names:
Other Names:
|
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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Maximum Tolerated Dose, Dose Limiting Toxicity
Time Frame: First Cycle
|
DLT (dose limiting toxicities): patients with any of the toxicities: 1.Haematological toxicity is not included in the definition due to bone marrow involvement by the disease except for following grade 4 ANC (absolute neutrophil count) and PLT (platelet count) for 6 weeks with less than 5% blasts in bone marrow.
2.Drug related non hematological Grade 3 or 4 toxicity except alopecia, brief nausea and vomiting, diarrhea, rash, arthralgias and myalgias.
Treatment interventions should palliate toxicity symptoms prior to concluding a DLT has occurred (e.g if nausea and vomiting to Grade 3 have been associated with the drug).
If despite standard treatment Grade 3 nausea and or vomiting persisted then a DLT was considered to have occurred.
Grade 4 diarrhea in spite of standard therapeutic measures was included in DLT definition.
3.Inability to tolerate full dosing cycle due to toxicity or any drug-related adverse event resulting in more than 14 day treatment delay in the next treatment cycle

First Cycle
|
Overall Response
Time Frame: Throughout study, after each cycle for the first two cycles, then after every second cycle
|
Efficacy measured as Response rate (complete response ([CR] and Complete remission with incomplete recovery of platelets [CRi]) and partial response ([PR])) using the response criteria of the International Working Group (Cheson et al 2003).
CR includes CRi, CRc (Cytogenetic complete remission), and CRm (Molecular complete remission).
