Summary

This trial, Treatment of NF1-related plexiform neurofibroma with trametinib; a single arm,open-label study with the goals of volumetric partial remission and pain relief (EudraCT 2018-001846-32, Sponsor protocol number BUS2018-1, related Novartis reference number CTMT212ASE01T) is a pediatric clinical trial that investigates the potential use of the drug trametinib (Mekinist®) as treatment for symptomatic or likely to become symptomatic NF1-related plexiform neurofibromas (PN) in children between 1 year and 17 year and 11 months of age. Trametinib is orally administered qd at 0.025 mg/kg up to a maximum of 2 mg from six years of age and 0.032mg/kilo up to 5 years of age, provided either as tablets or as oral solution. It is manufactured and distributed by Novartis under the trade name Mekinist®. The primary endpoint is remission of tumor volume ≥20%, evaluated using volumetric MRI at 18 and 30 months of treatment. The secondary endpoint is reversal of pain from NF1-related PN, evaluated monthly with agespecific pain scales; VAS scale (from 8 years) or Faces Pain Scale (from 3 to 8 years). As an exploratory measure, the potential effects of the treatment on the cognitive function will be assessed using well-established tests such as WISC-V (age range 6:0 - 16:11), NEPSY-II (age range 3:0-16:11), and CPT-3 (age range 8:0 - adult). Cognitive dysfunction is well described in patients with NF1, and the MAPK/ERK-pathway has been indicated to be involved in cognition.

Inclusion Criteria * NF1-related PN with severe - or with high suspicion of becoming severe - manifestations * Informed consent provided * Age 1:0-17:11 Exclusion Criteria * NF1-related PN does not fulfill characteristics for acceptable volumetric MRI assessments as outlined under Criteria for volumetric assessment. * Lactating or pregnant females. Sexually active females, who do not (agree to) use safe contraception or adhere to regular controls during study. Sexually active males who do not (agree to) use a condom during coitus. * A history of other malignancies than classic NF1-related WHO grade 1 tumors (i.e. PN or optic pathway glioma). * A history of NF-1 related cerebral vascular anomalies (such as Moyamoya). * Active pharmaceutical therapy for optic pathway malignancy/ies. * Any medication for treatment of left ventricular systolic dysfunction. * Use of any investigational drug within 30 days of the first dose of this study treatment. * Impaired renal function (GFR under 45 ml/min/1,73m2 - It is only required to analyze eGFR if creatine is above institutional reference value for corresponding age group). * A known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to the study drug or excipients that contraindicate their participation. * Active liver or biliary disease or moderate or severe liver impairment. If there are signs of liver disease (such as an increased prothrombin time or elevated transaminases),grading of the liver impairment has to be done in consultation with a hepatologist, since there is no universal definition. * A history of hepatic sinusoid obstructive syndrome (venoocclusive disease) within the last 3 months. * A history of heparin-induced thrombocytopenia. * A history of interstitial lung disease or pneumonitis. * A history of retinal vein occlusion (RVO). * A history of Hepatitis B Virus (HBV), or Hepatitis C Virus (HCV) infection. Subjects with a confirmed cleared HBV and HCV infection may be enrolled. * Presence of a condition that will interfere significantly with the absorption of drugs. * Evidence of cardiovascular risk, such as left ventricular ejection fraction (LVEF) below the lower limit of normal (LLN), a corrected QT-interval (Qtc) \>480 milliseconds, clinically significant uncontrolled arrhythmia, congestive heart failure, or acute coronary syndrome or history thereof.
