Midostaurin

EFS was defined as the time from randomization to failure to obtain a complete remission (CR) or Complete remission with incomplete hematologic recovery (CRi) with adequate blood count recovery in induction, relapse after CR or CRi with adequate blood count recovery or death due to any cause, whichever occurred first as assessed by the investigator.

Safety of Midostaurin was represented by various types of AEs, SAEs \& death up to M24. AE: the appearance of (or worsening of any pre-existing) undesirable sign(s), symptom(s), or medical condition(s) that occur after patient's signed informed consent has been obtained. AE grades to characterize the severity of AEs were based on the Common Terminology Criteria for AEs ver. 4.03 with Grade (Gr) 1: mild; Gr 2: moderate; Gr 3: severe; Gr 4: life-threatening; Gr 5: death related to AE. AEs not related to hematological toxicities were generally of grade 1 or 2 severity. SAE: 1 of the following: is fatal or life-threatening, results in persistent or significant disability/incapacity, constitutes a congenital anomaly/birth defect, is medically significant, i.e. an event that jeopardizes the patient or may require medical or surgical intervention to prevent 1 of the outcomes listed above, requires inpatient hospitalization or prolongation of existing hospitalization with a few exceptions.

To perform two predefined subgroup analyses in the age-groups 18-60 years and 61-70 years evaluating the impact of midostaurin given in combination with intensive induction, consolidation including allogeneic hematopoietic stem cell transplantation and single agent maintenance therapy on event-free survival (EFS) in adult patients with AML exhibiting a FLT3-ITD.

Dose-limiting toxicity (DLT) is defined as any death due to toxicity related to study treatment (chemotherapy + midostaurin) and/or any CTCAE grade 4 non-hematological adverse event or abnormal laboratory value grade 4 related to study treatment unless the event improves sufficiently by day 42 and therefore does not further delay the next cycle of study treatment.

Safety profile includes type, frequency and severity of adverse events during the induction, consolidation and post consolidation phase. AEs are also collected during post treatment follow-up phase

Number of dose interruptions/reductions and discontinuations due to study drug

Percentage of Safety Events, defined as death or serious adverse event leading to treatment discontinuation that occurs on or before Day 21 of the first Consolidation cycle. This was determined by the Independent Safety Committee (ISC) to be definitely or probably related to midostaurin. Percentage was calculated based on the percentage of subjects with safety event out of 3 evaluable subjects in Part 1.

Event Free survival is defined as the time from the date of randomization until an EFS event is observed. An EFS event is defined as a failure to obtain a complete remission (CR) within an induction 2, relapse after CR, or death due to any cause, whichever occurs first. The objective was to evaluate the efficacy based on EFS of midostaurin versus placebo in combination with daunorubicin/cytarabine induction, with high-dose cytarabine consolidation, and with midostaurin single agent continuation therapy in newly diagnosed patients with FLT3-mutated AML.

Relapse-free survival assesses the clinical benefit of remaining in remission free from relapse or death due to the disease. It was defined as the time from transplant to relapse or death due to the disease. Relapse following complete response was defined as reappearance of leukemic blasts in the peripheral blood or finding more than 5% blasts in the bone marrow.

Overall Response Rate (ORR) was defined as the percentage of participants who classified as confirmed responders (Major Response (MR) or Partial Response (PR)) by the adjudication of the SSC and based on a Modified Valent Criteria. A major responder had complete resolution of at least one C-Finding and no progression in other C-Findings. A partial responder showed a measurable improvement in one or more C-Finding(s) without confirmed progression in other C-Findings. A C-Finding was a Clinical Finding, which was considered by the investigator and corroborated by the Study Steering Committee (SSC) Chairperson or designee, attributable to the mast cell disease component and not the associated hematological clonal non-mast cell lineage disease (AHNMD) component or any other cause.

Clinical Response \[PR + CR\] will be assessed after 2 cycles of treatment, with each cycle being 28 days (4 weeks) in length. Except as otherwise noted, the minimum criteria for PR is improvement by at least 50% from the baseline value towards the indicated value for one or more of the criteria below: BONE MARROW \& BLOOD * ANC \<1000/uL * Hb \<10 g/dL * Platelets \>100,000/uL LIVER * If hepatomegaly with ascites, decrease in frequency of paracenteses by 50% * Elevated enzyme levels \> upper limit of normal (ULN) * Hypoalbuminemia \< ULN * Portal hypertension \> ULN SPLEEN * If palpable splenomegaly with hypersplenism/thrombocytopenia, hypersplenism markers improved GI TRACT * If malabsorption with hypoalbuminemia and/or weight loss, albumin improved BONES * If huge osteolyses or/and severe osteoporosis with pathologic fractures, partial resolution of osteolyses Subjects with PR or greater continue, those without response discontinue.

In subjects with Child Pugh A, Child Pugh B (and matching healthy volunteers) Cmax will be measured at Day 1 and Day 7. In subjects with Child Pugh C (and matching healthy volunteers) Cmax will be measured at Day 1
