Outcome measures
Primary outcome
• Cumulative CR/CRi rate after 3 cycles
Secondary outcome
• Safety and tolerability (frequency and severity of toxicities and the
durations of neutropenia and thrombocytopenia).
• Efficacy profile (response rate (CR, CRi, PR), event free survival (EFS) and
overall survival (OS)).
• Days of staying in hospital and transfusion needs.
• Prognostic value of MRD (by flowcytometry or PCR).
• Gene mutations predictive of response, EFS and OS by exploratory analysis.
• Prognostic value of baseline physical and functional conditions using
comprehensive geriatric assessment tools (short physical performance battery
(SPPB) and activities of daily living (ADL) on treatment outcome.
Translational endpoints
• To determine the impact of 3 days ibrutinib monotherapy (pre-treatment) on
WBC count, circulating blast count, and kinome (using mass cytometry kinome).
• To identify potential biomarkers (using mass cytometry kinome; methylome) in
bone marrow and peripheral blood which are of prognostic importance in both
arms, and whether they are of predictive importance for response.
• To identify methylome profiles in CD34+ bone marrow blasts and stroma cells
which are of prognostic importance in both arms, and whether they are of
predictive importance for response.
Background summary
This trial aims to develop effective treatments for UNFIT (i.e. hematopoietic
cell transplantation co-morbidity index (HCT-CI) >= 3) in older (>= 66 yrs) AML
patients, for whom current treatment strategies are highly unsatisfactory.
Therefore new treatment modalities are introduced and evaluated in multiple
parallel randomized phase II studies that will be conducted within the frame of
a master protocol. The scheme of this new design consists of one arm with one
of the currently considered best available treatments for UNFIT older AML
patients (i.e. 10-day decitabine). After a maximum of 3 10-day courses, or less
in case of good response, treatment will be continued with 5-day decitabine
courses. This treatment will be compared to investigational treatments in
combination with decitabine.
The first competitor of the 10-day decitabine schedule will be 10-day
decitabine combined (sequential) with the BTK inhibitor ibrutinib. The
rationale for ibrutinib is:1) its high expression and phosphorylation in AML
cell lines and CD34+ AML blasts; 2) the central role of BTK within many
important signaling pathways in AML (e.g. CXCR4, TLR, Flt3-ITD); 3) the
in-vitro activity of ibrutinib against AML blasts; 4) extensive experience with
ibrutinib combined with chemotherapy in mantle cell lymphoma and CLL.
Study objective
Primary objectives
1. To assess in a randomized comparison the effect of Ibrutinib added to 10-day
decitabine treatment on the cumulative CR/CRi rate after 3 cycles.
Secondary objectives
1. To assess the safety and tolerability of Ibrutinib added to 10-day
decitabine treatment for AML (frequency and severity of toxicities and the
durations of neutropenia and thrombocytopenia).
2. To determine the efficacy profile: response rate (CR, CRi, PR), event free
survival (EFS) and overall survival (OS) associated with the two therapy
regimens (i.e. decitabine vs decitabine + ibrutinib.
3. To determine the impact of 3 days ibrutinib monotherapy (pre-treatment) on
WBC count, circulating blast count, and translational endpoints (mass
cytometry).
4. To measure MRD by immunophenotyping and PCR in relation to clinical response
parameters.
5. To identify potential biomarkers predictive of response, EFS and OS by
exploratory analysis (gene mutations, kinome, methylome).
6. To evaluate the prognostic value of baseline physical and functional
conditions using comprehensive geriatric assessment tools (short physical
performance battery (SPPB) and activities of daily living (ADL) on treatment
outcome).
Study design
This is a prospective, open label, multicenter study that is conducted in the
frame of a masterprotocol with multiple parallel randomized phase II arms.
Intervention
Patients in this study are treated with 10-day decitabine treatment with or
without ibrutinib. The starting dose of ibrutinib will be 560 mg once daily.
During the part A run-in phase the dose level of ibrutinib will be established.
Study burden and risks
The benefit of this study is that older AML patients with co-morbidities: 1) do
not receive toxic intensive chemotherapy (which has been shown to be associated
with an almost 30% day-28 mortality); 2) do receive treatment (instead of not
being considered for treatment at all).
The burden and risks associated with participation mainly involve an additional
bone marrow aspirate and blood draw at day+1 in arm B and taking off additional
material during routine examinations (blood draws/bone marrow aspirates).
Furthermore, a geriatric assessment will be performed.
