Official Title  ICMJE HDM201 and Midostaurin (HDMM) in Relapsed/Refractory AML With FLT3mut and TP53wt; a Phase I Study.
Brief Summary This is a non-randomized prospective open-label single-arm clinical phase I trial investigating dose finding, feasibility and safety of the combined treatment of HDM201 and midostaurin in patients with relapsed/refractory acute myeloid leukemia (AML) with FLT3mut applying an accelerated titration design.
Detailed Description

Background and Rationale:

Acute myeloid leukemia (AML) is a clonal hematopoietic malignant disease characterized by genetic and epigenetic alterations leading to inactivation of the tumor suppressor p53. This contributes to a block in normal differentiation of the various blood type lineages and to an accumulation of leukemic blasts in the blood and bone marrow. The disease variants have been grouped into favorable, intermediate and poor risk categories. The largest group of poor risk AML is characterized by the genetic alterations of the FLT3 receptor gene termed FLT3-ITD or FLT3-TKD. The prognosis for this specific subset which comprises 25-35% of all AML patients is generally poor, particularly in elderly or in relapsed patients, highlighting the unmet need for novel treatments.

Targeting the mutated FLT3 receptor is a promising approach to treat this specific poor risk AML subset. Midostaurin is particularly effective to induce cell death in FLT3-ITD/-TKD and TP53wt cells. Targeting MDM2 is a novel approach to restore the crucial p53 tumor suppressor function in AML cells. Preliminary data indicate that the MDM2 inhibitor HDM201 is active in AML cell lines in vitro and in vivo. Like midostaurin HDM201 is specifically effective to induce cell death in FLT3-ITD and TP53wt cells. The combination of midostaurin and HDM201 targets FLT3-ITD AML cells, with little effect on FLT3 wt cells and healthy blood cells. Both compounds induce apoptosis and cell death in a dose-dependent manner in FLT3-ITD TP53wt AML cells, with enhanced effects in the combination treatment. The combination treatment with midostaurin and HDM201 ought to be superior to the current best available treatment which utilizes intensive genotoxic induction therapy. In order to confirm inhibition of mutated FLT3 receptor and restoration of p53 tumor suppressor function, blood samples will be analyzed in this trial before, during and after treatment with HDM201 and midostaurin for changes in the expression of FLT3 and p53 target genes as well as induction of pro- apoptotic genes. These gene expression levels will be correlated with clinical response and outcome.

Objectives:

Primary objective:

The primary objective of this trial is to establish the recommended dose for a subsequent phase II (RP2D) of HDM201 in combination with midostaurin in patients with relapsed or refractory FLT3mut TP53wt AML.

Secondary objectives:

The secondary objectives are to determine the safety and tolerability of HDM201 in combination with midostaurin and to assess the preliminary antitumor activity of HDM201 in combination with midostaurin in patients with relapsed or refractory FLT3mut TP53wt AML and in newly diagnosed AML with FLT3mut and TP53wt.

Study Duration:

The trial study duration encompasses the time from when the first participant signs the informed consent until the last protocol-specific procedure of the last patient in the trial has been completed.

This phase I trial involves a minimum of 3 and a maximum of 24 subjects. Accordingly, the Investigator anticipate a duration of recruitment of between 3 and 18 months.

All patients will be followed up for up to 12 months after end of treatment, adding to a total study duration of between 15 and 33 months depending on the effective number of patients in the various dose cohorts.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • AML with FLT3-ITD or FLT3-TKD and TP53wt.
  • Age over 18 years
  • Patient must give written informed consent before registration indicating that the patient understands the purpose of the procedures required for the trial and is willing to participate in the trial.
  • Patients with relapsed/refractory disease must have morphologic proof (from bone marrow aspirate, smears or touch preps of bone marrow biopsy) of AML with >= 10% blasts within two weeks (14 days) prior to initiation of therapy.
  • Patients must demonstrate one of the following: Relapse after first complete remission or refractory to conventional induction chemotherapy (failure to respond to 1 or more cycles of daunorubicin and cytarabine) or to re-induction.
  • Patients with previously untreated AML are candidates if they are unable to receive an anthracyclin, and have documented AML with ≥ 20% blasts within one week prior to enrollment.

    • AST ≤ 3 times ULN
    • Alanine aminotransferase (ALT) ≤ 3 times ULN
    • Serum total bilirubin ≤ 1.5 times ULN, unless in case of hyperbilirubinemia due to an isolated Gilbert syndrome

  • Prior allogeneic bone marrow or solid organ transplantation
  • Any life-threatening illness, medical condition, or organ system dysfunction which, in the investigator's opinion,

    • could impair the ability of the patient to participate in the trial
    • could compromise the patient's safety,
    • could interfere with the absorption or metabolism of midostaurin or HDM201,

In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
    • Male sterilization (at least 12 months prior to screening). The vasectomized male partner should be the sole partner for that subject
    • Use of oral, injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception.
    • Midostaurin may reduce the effectiveness of hormonal contraceptives; therefore, females using systemically active hormonal contraceptives should add a barrier method of contraception.
