1. Overview


A randomized phase II multicenter study to assess the tolerability and efficacy of the addition of midostaurin to 10-day decitabine in unfit (i.e. HCT-CI ≥ 3) adult AML and high risk myelodysplasia (MDS) (IPSS-R > 4.5) patients.

A study in the frame of the masterprotocol of parallel randomized phase II studies in UNFIT- AML/high-risk MDS patients.

Study objectives

Primary objectives:
To assess in a randomized comparison the effect of midostaurin added to 10-day decitabine treatment on the cumulative CR/CRi rate during 3 cycles.

Secondary objectives:

To assess the safety and tolerability of midostaurin added to 10-day decitabine treatment for AML (frequency and severity of toxicities and the durations of neutropenia and thrombocytopenia) as regards to the selected dose level of the study.

To determine the efficacy profile: response rate (CRMRD-, CR, CRi, MLFS, PR), event free survival (EFS) and overall survival (OS) associated with the two therapy regimens.

To measure MRD by immunophenotyping and PCR in relation to clinical response parameters.

To identify gene mutations as potential biomarkers predictive of response, EFS and OS by exploratory analysis.

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.

2. Patient eligibility criteria

Inclusion criteria

•Patients with:
a diagnosis of AML and related precursor neoplasms according to WHO 2016 classification (excluding acute promyelocytic leukemia) including secondary AML (after an antecedent hematological disease (e.g. MDS) and therapy-related AML, or

•Adequate renal and hepatic functions unless clearly disease related as indicated by the following laboratory values:
Serum creatinine ≤ 221.7 µmol/L (≤ 2.5 mg/dL ), unless considered AML-related
Serum bilirubin ≤ 2.5 x upper limit of normal (ULN), unless considered AML-related or due to Gilbert’s syndrome
Alanine transaminase (ALT) ≤ 2.5 x ULN, unless considered AML-related
• WHO performance status 0, 1 or 2 (see Appendix D).
• Patient is willing and able to use adequate contraception during and until 5 months after the last protocol treatment.

• Blast crisis of chronic myeloid leukemia.
• Diagnosis of any previous or concomitant malignancy is an exclusion criterion:
• except when the patient completed successfully treatment (chemotherapy and/or surgery and/or radiotherapy) with curative intent for this malignancy at least 6 months prior to randomization. OR
• except for basal and squamous cell carcinoma of the skin or in situ carcinoma of the cervix
• Patients previously treated for AML (any antileukemic therapy including investigational agents), a short treatment period ( ≤ 5 days) with Hydroxyurea is allowed
• Current concomitant chemotherapy, radiation therapy, or immunotherapy; other than hydroxyurea
• Concurrent severe and/or uncontrolled medical condition (e.g. uncontrolled diabetes, infection, hypertension, pulmonary disease etc.)

• Patients known to be pregnant
• Patients with a history of non-compliance to medical regimens or who are considered unreliable with respect to compliance.
• Patients with any serious concomitant medical condition which could, in the opinion of the investigator, compromise participation in the study.
• Patients who have senile dementia, mental impairment or any other psychiatric disorder that prohibits the patient from understanding and giving informed consent.
• Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule
