Background summary
Nilotinib (AMN107) is a novel, oral ATP-competitive inhibitor of BCR-ABL
tyrosine kinase
with improved potency and greater target selectivity compared to that of
imatinib.
Nilotinib is currently approved for the treatment of adult patients with Ph+
CML in CP or
AP resistant or intolerant to prior therapy including imatinib and for the
treatment of adult
patients with newly diagnosed Ph+ CML in CP, at 400 mg bid and 300 mg bid,
respectively.
A Phase I dose-escalation study followed by a Phase II study [CAMN107A2101] in
adult
patients with imatinib resistant or intolerant Philadelphia chromosome positive
chronic
myelogenous leukemia (Ph+ CML), Philadelphia chromosome positive acute
lymphoblastic leukemia (Ph+ ALL), and other hematologic malignancies
demonstrated
that nilotinib taken at the recommended dose of 400 mg twice daily was
effective and
well tolerated. A Phase III randomized study [CAMN107A2303] ]in newly diagnosed
adult
patients with Ph+ CML CP showed superiority of nilotinib vs. imatinib. At the
12-month
analysis time point: the MMR rate was significantly higher with nilotinib
compared to
imatinib. By 36 months, the MMR rate as well as the estimated rate of patients
free from
progression to AP/BC remained higher with nilotinib than with imatinib.
Tasigna® is currently approved and marketed as an immediate
release hard gelatin capsule at the dose strength of 150 mg and 200 mg.
Despite the success of imatinib used as either a single agent for Ph+ CML or in
combination with chemotherapy for Ph+ ALL, resistance or persistence of disease
or
intolerance to imatinib occurs in many patients. Nilotinib is a TKI that was
designed to be
a more specific inhibitor of BCR-ABL than imatinib. Adult patients have
demonstrated a
benefit from switching to 2nd-generation TKIs such as nilotinib. The positive
benefit/risk
profile demonstrated by nilotinib in adult patients with newly diagnosed as
well as
imatinib resistant/intolerant Ph+ leukemias may also be demonstrated in
pediatric Ph+
leukemia patients as they are also characterized by t(9:22) and expression of
the BCRABL
oncoprotein.
The pharmacokinetics (PK) of nilotinib has been characterized previously in
adult
patients and healthy volunteers. However, limited information/data has been
obtained
regarding the PK profiles of nilotinib in patients of ages less than 18 years.
The
metabolism of nilotinib has been shown to be primarily mediated by cytochrome
P450
3A4 (CYP3A4), and to a very minor extent, by CYP2C8. Based on literature
reportreports, the CYP3A4 expression and activity reaches its adult level at
1-2 years
after birth (Johnson, et al 2006). Therefore no significant difference in the
metabolism of
nilotinib is expected between the pediatric (>=1 year) and adult populations.
The current study is proposed to evaluate the PK of nilotinib in pediatric
patients with
newly diagnosed CP Ph+ CML, with CP or AP Ph+ CML resistant / intolerant to
imatinib
and/or dasatinib, or with Ph+ ALL refractory /relapsed to standard
therapy.
Study objective
Primary: To characterize the PK of nilotinib in pediatric patients with newly
diagnosed CP Ph+ CML, with CP or AP Ph+ CML
resistant / intolerant to imatinib and/or dasatinib, or with Ph+ ALL
refractory/relapsed.
Secondary:
• To assess the safety and tolerability of nilotinib.
• To assess the pharmacodynamics of nilotinib by its activity (hematologic,
cytogenetic and molecular responses).
• To assess mutations in BCR-ABL at baseline and at the end of study.
Study design
This is a PK study with the assessment of nilotinib safety and activity as
secondary endpoints.
Intervention
The approved adult dose of nilotinib for the treatment of imatinib resistant /
intolerant CML is 400mg twice daily. The equivalent dose, based on an
average BSA of 1.73 m2 in adults, is 230 mg/m2 twice daily which will be
investigated in this trial.
Study burden and risks
Extra procedures compared to standard treatment are:
Hospitalisation/stay in the institute will be extended on the day of
pharmacokinetic sampling.

headache, tiredness, muscle pain, itching, rash, hives and hair loss ,vomiting,
abdominal pain, stomach discomfort after meals, flatulence, bone pain, pain in
joints, muscle spasms, pain in extremity, back pain, flank pain, skin
reddening, dry skin, acne, skin wart, decreased skin sensitivity, weight
decrease or increase, decreased appetite, insomnia, night sweats, excessive
sweating, hot flushes, voice disorder, eye itching and dry eyes.

Inclusion criteria
1. Male or female patients less than 18 years and more than 1 year of age at study entry.

a.
• Imatinib or dasatinib resistance in Ph+ CML is defined as:
• Increasing WBC or platelet count while on imatinib or dasatinib therapy indicative of a
hematological relapse or primary resistance to imatinib or dasatinib
• Cytogenetic or molecular response consistent with suboptimal response or failure criteria adapted from ELN (European Leukemia Net) recommendations
• Progression to accelerated phase or blast crisis while on imatinib or dasatinib therapy.
