Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In the main study, Cohorts 1 and 2 will all receive Trametinib intervention as follows:
Cohort 1: Neurofibromatosis Type 1 associated Plexiform Neurofibroma (NF1-PN)
Cohort 2: Neurofibromatosis Type 1 associated Optic Pathway Glioma (NF1-OPG)
Drug: Trametinib
Dose: 0.025mg/kg once daily for children 6 years and over, 0.032mg/kg once daily for children under 6.
Duration: 24 months
Mode of administration: Oral
Formulation: 0.5 or 2mg tablets; or Solution (for participants under 6 years old, or those 6 years old and over who are unable to swallow tablets).
Compliance to drug administration will be monitored by use of a participant drug diary and measurement of bottle returns.

In the sub-study, a suite of neurocognitive, quality of life and behaviour assessments and questionnaires will be evaluated in the treated Cohort 1 (NF1-PN) and Cohort 2 (NF1-OPG) and in a control group of untreated participants with Neurofibromatosis Type 1.
Intervention code [1] 316819 0
Treatment: Drugs
Comparator / control treatment
There will be no control group for the main study: tumour response, vision, safety and survival outcomes.

A control group of 60 participants will be used for the neurocognitive, behavioural and quality of life Substudy. This control group will consist of participants with NF1 and who are ineligible for the PN or OPG cohort. The control will receive no treatment and only participate in the assessments for neurocognition, behaviour and quality of life at the specified timepoints.

Efficacy
Statistical methods / analysis
Descriptive statistics will be used to show trametinib efficacy separately in the PN and OPG cohorts as the number and proportion of patients who have progressed, remained stable, or demonstrated a partial or complete response. The absolute percentage change in volume from baseline to 2 years within each group (mean and 95% CI) will be described. The difference in visual acuity from baseline to 2 years will be described (mean and 95% CI) for the OPG cohort only.

For the neurocognitive, pain and QoL substudy:

Neurocognitive/behaviour: For neurocognitive function and behaviour ratings, the two treated groups will be combined. Adjusted mean differences between groups and 2-sided 95% confidence intervals at 6, 12 and 24 months will be calculated using separate linear regression models for each time point adjusted for baseline and age. The key comparison of interest for all neurocognitive and behavioural outcomes will be the between-group difference at 24 months. We will also consider whether there is a linear trend over time in neurocognitive and behavioural outcomes by fitting a linear mixed model to the data from all four time points (baseline, 6, 12, and 24 months) simultaneously. The model will include a random effect for intercept (to allow for the clustering of repeated measures) and fixed effects for group, time (e.g. study visit), group by time interaction and matching factor (age). As additional exploratory analyses, we will also repeat the above analysis including group as a 3 level variable - PN, OPG and untreated controls.
As an exploratory analysis, we will examine the association between change from baseline to 24mths in QoL and in the primary outcome for each treated group (and pain for the PN group) using Pearson’s (or Kendall’s tau for non-parametric) correlations. For distress ratings, descriptive statistics (mean, standard deviation and proportion of participants with ratings above the clinical cut-off score) will be provided for each group.

QoL: Unlike the neurocognitive outcomes, for which we expect an equivalent effect of trametinib in both treated groups, it is possible that tumour-specific factors may result in cohort-specific treatment effects on QoL outcomes for the OPG and PN groups. Thus, to determine whether it is possible to combine treated groups (PN and OPG) into a single treatment condition, or whether we should analyse PN and OPG cohorts separately, we will first conduct linear regression examining mean between-group differences (OPG vs PN) at t each time point (6, 12, 24 months) adjusted for baseline and age on the following QoL outcomes: (1) PedsQL Generic Core, Psychosocial Health Summary Score; (2) PedsQL Family Impact Module, Family Functioning Scale; (3) Peds QL Multidimensional Fatigue Scale, total summary score; (4) PedsQL NF1 Module, Cognitive QoL score; (5) Quality-adjusted life years (EQ-5D/EQ-5D-Y); and (6) Parent distress. If there is strong evidence of a difference between OPG and PN groups on a specific outcome, treated groups will be analysed separately for that outcome. If there is little evidence for between-group differences, then treated groups will be combined for that particular outcome. Regardless of whether these treated groups are combined or analysed separately, each outcome will be compared to the untreated control group. Adjusted mean differences between groups and 2-sided 95% confidence intervals at 6, 12 and 24 months will be calculated using separate linear regression models for each outcome time point adjusted for baseline and age. The key comparison of interest for all QoL outcomes will be between-group difference at 24 months. at 24 months. We will also consider whether there is a linear trend over time in the QOL outcomes and whether this trend varies by group by fitting a linear mixed model to the data from all 4 time points (baseline, 6, 12 and 24 months) simultaneously. The model will include a random effect for the intercept (to allow for the clustering of repeated measures) and fixed effects for group, time (e.g. study visit), group by time interaction, and matching factor (age).

Pain: Descriptive statistics (mean and standard deviation) will be provided for change in pain measures from baseline in the PN group only, to each time point. Only the PN cohort will be described as we are primarily interested on the effects trametinib may have on PN-related pain.

Visual QoL: Descriptive statistics (mean and standard deviation) will be provided for the change in visual QoL measure in the OPG group only, at each time point. Only the OPG cohort will be described as we are primarily interested on the effects trametinib may have on vision-related QoL as a result of treating OPGs.

Summary
Brief summary
The purpose of this study is to determine if a targeted therapy (a drug called trametinib) has an effect on tumour response in children, teenagers and young adults with neurofibromatosis type 1 (NF1) associated Plexiform Neurofibromas and Optic Pathway Gliomas.

Who is it for?
You may be eligible for the treatment arm of this study if you are between 3 months and 25 years old and have NF1 associated plexiform neurofibromas or progressive optic pathway gliomas. You may be eligible for the control arm of the substudy if you are between 3 months and 25 years old with NF1.

Study details
All participants in the main part of this study will receive the targeted therapy (trametinib) and are expected to take this drug daily for two years. The medication will be provided as either an oral tablet or an oral solution.

Participants taking trametinib will be expected to complete some assessments at enrolment and attend monthly hospital visits for general health reviews. Additionally, every three months for two years, assessments will include MRI scans, and cardiac and vision testing. These assessments will measure whether trametinib is effectively treating the tumour and will also monitor any side effects.

There is also a sub-study occurring within this study to find out if trametinib can improve learning, behaviour and well-being for those with NF1. For this part of the study, an untreated control group will be enrolled to compare to the trametinib-treated group described above. The untreated control group will be children, teenagers and young adults with NF1 who do not have a tumour that requires trametinib treatment. All participants in the trametinib-treated and the control groups will attend four Neuropsychology Clinic Visits over a two-year period. During these visits they will complete a number of questionnaires and tests to measure their cognitive function (thinking skills), behaviour and quality of life.

It is hoped this research will help determine if trametinib has an effect on tumours and if there are any additional impacts to cognitive function, behaviour and quality of life.
