Summary:
This is a clinical study aiming to assess pharmacokinetics, pharmacodynamics and
preliminary efficacy of ZE46-0134 in patients with FLT3 mutated Relapsed or Refractory
Acute Myeloid Leukemia
Detailed description:
This is a Phase 1, open-label, multicenter, dose escalation, and dose optimization study
to evaluate the safety, tolerability, PK, PD, and preliminary efficacy of ZE46-0134 in
adult patients with relapsed or refractory AML with FLT3-ITD and/or FLT3-TKD mutations.
Patients with AML that are out-patients or hospitalized due to their AML can be enrolled
in the study..
The study will be run in 2 parts: Part 1 will be dose escalation and determination of
MTD, and Part 2 will be dose expansion.
In Part 1 of the study 3 to 6 eligible patients will be sequentially enrolled into each
of 5 planned dose level cohorts. Patients will receive up to 24 cycles (28 days each) of
study treatment. For patients that continued to derive benefit after 24 cycles of
treatment, continuation of ZE46-0134 therapy will be considered.
In Part 2, the dose expansion phase will involve enrolling up to 30 patients across 2
dose cohorts (i.e., 15 patients per cohort). ZE46-0134 will be dosed as described for
Part 1 of the study. The doses used in Part 2 of the study will be determined based on
the data from Part 1 of the study.
Indication background information:
Acute myeloid leukemia (AML) comprises a heterogeneous group of aggressive blood cell
cancers that arise from clonal expansion of malignant hematopoietic precursor cells in
the bone marrow (BM) and is the most commonly diagnosed adult leukemia with a median age
at diagnosis is 68 years, with an overall survival (OS) rate of 29.8%. As patients age,
there is a 10% decrease in 5-year OS for every additional decade of life, with a 5-year
OS of 0.4% in patients age >85 years1. Furthermore, remission rates and OS depend on a
number of other factors, including cytogenetics, previous BM disorders, and
comorbidities.
FMS-like tyrosine kinase-3 (FLT3) is a receptor tyrosine kinase (RTK) primarily expressed
on immature hematopoietic progenitors and hematopoietic stem cells. FLT3 signaling is
initiated when FLT3 ligand binds to FLT3, inducing the dimerization and activation of
FLT3 via autophosphorylation. This then activates downstream signaling of
phosphoinositide 3-kinase/protein kinase B (PI3K/PKB), mitogen-activated protein kinase
(MAPK), and JAK2/STAT5 which leads to cell proliferation and suppression of apoptosis2.
FLT3 kinase is directly implicated in the pathogenesis of hematologic malignancies,
particularly AML. FLT3 mutations are the most frequently identified mutations in AML
patients. Activating mutations in FLT3, which are FLT3-internal tandom duplication (ITD)
and FLT3 tyrosine kinase domain (TKD) mutations, account for 30% of all AML cases2. As a
result of these mutations, the FLT3 receptor is continuously activated leading to the
continuous activation of downstream signaling pathways, PI3K/AKT, MAPK, and signal
transducer and activator of transcription (STAT5), resulting in increased cell
proliferation and decreased apoptosis.
