Brief Title
A Study of Selumetinib in Chinese Paediatric and Adult Subjects With Neurofibromatosis Type 1 (NF1) and Inoperable Plexiform Neurofibromas (PN)
Official Title
A Phase 1 Open Label Study to Assess the Safety, Tolerability, Pharmacokinetics and Clinical Efficacy of Selumetinib, a Selective Mitogen Activated Protein Kinase Kinase (MEK) 1 Inhibitor, in Chinese Paediatric and Adult Subjects With Neurofibromatosis Type 1 (NF1) and Inoperable Plexiform Neurofibromas (PN)
Brief Summary
A Phase 1 Open Label Study to Assess the Safety, Tolerability, Pharmacokinetics and Clinical
Efficacy of Selumetinib, a Selective Mitogen Activated Protein Kinase Kinase (MEK) 1
Inhibitor, in Chinese Paediatric and Adult Subjects with Neurofibromatosis Type 1 (NF1) and
Inoperable Plexiform Neurofibromas (PN)
Detailed Description
Paediatric and adult patients with Neurofibromatosis Type 1 (NF1) and Inoperable Plexiform
Neurofibromas (PN) will be evaluated in the screening visit to confirm eligibility.
Approximately 16 paediatric and 16 adult qualified patients will receive oral selumetinib 25
mg/m^2 twice a day (approximately every 12 hours) continuously until disease progression or
unacceptable drug-related toxicity, whichever occurs first. Once a patient has discontinued
the study treatment then the patient will be followed for specified period for safety
assessment

Eligibility Criteria
Inclusion Criteria:
- Paediatric cohort: Chinese subjects ≥3 years and <18 years of age
- Adult cohort: Chinese subjects ≥18 years of age at the time of study enrollment
- Subjects must be diagnosed with (i) NF1 as per NIH Consensus Development Conference
Statement and（ii) PN is defined as a neurofibroma that has grown along the length of a
nerve and may involve multiple fascicles and branches. (iii) inoperable PN
- Subjects must have at least one measurable typical or nodular PN
- Absolute neutrophil count ≥1.5×10^9/L, haemoglobin ≥9g/dL, and platelet count
≥100×10^9/L. Subject must be without growth factor support and platelet transfusion
support 7 days before the screening assessment.
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2×upper limit of
normal (ULN), total bilirubin ≤1.5×ULN except in the case of subjects with documented
Gilbert's disease (≤2.5×ULN).
Exclusion Criteria:
- Evidence of malignant peripheral nerve sheath tumour.
- Clinically significant cardiovascular disease
- Prior malignancy (except for adequately treated basal cell or squamous cell skin
cancer, in situ cervical cancer, or other cancer from which the subject had been
disease free for ≥2 years or which would not have limited survival to <2 years) or
other cancer requiring treatment with chemotherapy or radiation therapy.
- Subjects with the following ophthalmological findings/conditions:
Current or past history of retinal pigment epithelial detachment/central serous retinopathy
or retinal vein occlusion; Intraocular pressure >21 mmHg (or ULN adjusted by age) or
uncontrolled glaucoma (irrespective of IOP); Subjects with known glaucoma and increased IOP
who do not have meaningful vision (light perception only or no light perception) and are
not experiencing pain related to the glaucoma, may be eligible after discussion with the
study physician; Any other significant abnormality on ophthalmic examination that would
make the subject unsuitable for enrolment into the study, as assessed by the investigator.
