Selinexor (KPT-330) Plus FLAG-Ida for the Treatment of Relapsing/Refractory AML (FLAGINEXOR)

May 19, 2020 updated by: PETHEMA Foundation

An Investigator Sponsored Phase I Trial of Selinexor (KPT-330) Plus FLAG-Ida for the Treatment of Relapsing/Refractory AML

This protocol corresponds to a multicenter, open-label, non-randomized, phase I study designed to determine the safety of the combination of selinexor with chemotherapy in young patients with relapsed or refractory AML.

The clinical trial is divided into pre-treatment, treatment (induction and consolidation cycles) and follow-up periods and consists of a phase I design in which es-calating doses of selinexor will be given to 3 groups, each with 3-6 patients until achieving the maximum tolerated dose (MTD).

Detailed Description

Study Design:

This protocol corresponds to a multicenter, open-label, non-randomized, phase I study designed to determine the safety of the combination of selinexor with chemotherapy in young patients with relapsed or refractory AML.

The clinical trial is divided into pre-treatment, treatment (induction and consolidation cycles) and follow-up periods and consists of a phase I design in which es-calating doses of selinexor will be given to 3 groups, each with 3-6 patients until achieving the maximum tolerated dose (MTD).

Each cycle (second induction, consolidation or maintenance) of treatment will compromise 3 weeks of selinexor treatment, and at least one week off treatment. The new cycle will not start if there is an ongoing grade 3 or higher non-hematologic toxicity or persistent grade 3 neutropenia in patients achieving CR.

Study design allows a maximum of 18 patients.

Induction cycle (up to 2 cycles):

Treatment will consist of fludarabine 30 mg/m2/day intravenously on days 1 to 4, idarubicin 10 mg/m2/day intravenously on days 1 to 3, cytarabine 2 g/m2/day intravenously on days 1 to 4, G-CSF 300 mcg/m2/day subcutaneously from days -1 to 5. This schedule will be combined with oral selinexor (KPT-330) for three weeks at days and dose according to escalation level:

  • Level -1: Selinexor 40 mg/day, once weekly
  • Level 1: Selinexor 60 mg/day, once weekly
  • Level 2: Selinexor 80 mg/day, once weekly
  • Level 3: Selinexor 100 mg/day, once weekly If a partial response is obtained after the first cycle of treatment, an identical induction therapy will be administered.

If a patient achieves a complete remission after 1 or 2 cycles of FLAG-IDA plus selinexor, allogeneic stem cell transplantation (Allo-SCT) will be attempted. If Allo-SCT is not possible, this patient will receive consolidation treatment as described below.

Consolidation cycle (up to 2 cycles):

Treatment will consist of cytarabine 1 g/m2/day intravenously (3 hours) on days 1 to 6. This schedule will be combined with oral selinexor (the same dosage that was administered to the patient in the induction cycle).

At most, patients will receive up to 4 cycles of combined chemotherapy.

Maintenance cycle:

For patients in CR, and when an Allo-SCT is not feasible, a maintenance treatment with selinexor could be started for up to 6 cycles.

Selinexor will be given at the same level as during induction therapy in cycles of four weeks (3 weeks on selinexor and 1 week off).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Maximum tolerated dose (MTD) of selinexor in combination with FLAG-Ida regimen
Time Frame: At the end of Cycle 1 (each cycle is 56 days)

A standard 3 + 3 dose escalation schedule will be used for all escalations. Initially, three patients will be entered in each cohort at the scheduled starting dose level for that cohort. If a drug-related DLT (see Section 5.1.5.3) is not seen at the scheduled dose, the dose will be escalated for the subsequent group of 3 patients.

If 1 of 3 patients experiences a drug-related DLT, then 3 additional patients will receive that dose. If ≤ 2 of 6 patients experiences a drug-related DLT, the next scheduled dose level will be available. If, at a given dose level, > 2 patients experience a drug-related DLT, the MTD will have been exceeded, additional enrollment within that cohort will cease, and dose escalation will stop.

If a dose level proves intolerable (≥ 3 patients experience a DLT), enrollment will proceed at one dose-level lower.
